Some notes about installing Linux on a Dell minitower with a GPU and user policy. Note: this file is evolving into the following collaborative set of notes on CoCalc:

Swan Policies

Disk

  • /home/${USER}: Your home folder. Keep the size of your home directory minimal (<2GB). I would like to implement automatic backups of these (not yet implemented), so important information should be kept here, but no working or temporary data.
  • /data/users/${USER}: Your personal user space on the main hard-drive. Keep this as small as possible. I would also like to keep this backed up (not yet implemented).
  • /data2/users/${USER}: Your personal user space on the large external hard-drive. This will not be backed up.

In addition there is shared space which should be accessible to everyone in the :student group.

  • /data2/shared/: Shared space (not backed up).

To find out which directories are taking up space, the following command is useful:

du -sh * | sort -h

Please symlink your ~/.conda directory to /data2 so that when you create environments, you don't overuse space:

mkdir -p /data2/users/${USER}
mv ~/.conda /data2/users/${USER}/      # If you already have ~/.conda
mkdir -p /data2/users/${USER}/.conda   # If you do not have ~/.conda
ln -s /data2/users/${USER}/.conda ~/

Install

To install, I used a USB:

  1. Download the Lubuntu ISO
  2. Check for corruption (18.04 Release notes):
    md5 ~/Downloads/lubuntu-18.04-alternate-i386.iso
  3. Make a bootable USB drive. (From my Mac I used Disk Utility to erase the drive,

OS

Decide which version of Linux you want.

Distribution: The first choice is which Linux Distribution you want to use. I chose [Ubuntu] since it is the most popular, and has lots of support. Another good option might be openSUSE.

Flavour: The next choice is Flavour, which mostly affects the GUI. Since I run a (mostly-headless) server, I chose to start with Lubuntu which I initially installed from a thumb-drive. This is fairly lightweight, and minimal.

Release: The next choice is which version of Ubuntu to upgrade to. As discussed here: "How do I decide what version of Ubuntu to install", you should basically choose either the highest revision or highest LTS revision as listed on Official Ubuntu Releases site. The LTS versions will have Long Term Support, and hence will require fewer updates. Another consideration might be which versions are supported by CUDA which would probably favour an LTS release.

After a few upgrades (18.04.2 LTS -> 18.10) I have the following:

There were a few things I had to do:

  • Manually configure the network interface (static IP in the department).
  • Install an ssh daemon:
sudo apt-get install openssh-server

Configuration

I added some modification to the default bash initialization files. These will apply for all users and add the following features (see the Config Files section for the exact implementation).

  • Alias source with source_if_exists which does not fail if file does not exist.
  • Allow for tracing of init files by touch ~/.trace.
  • Provide some useful bash completions (tab completion of various commands).
  • Sets up the modules system (see the Modules section).
  • Adds the system conda environments for the user and provides the alias j for starting Jupyter notebooks with appropriate port forwarding.
  • Use etckeeper to keep track of configuration:
    sudo apt-get update
sudo apt-get install hg etckeeper
sudo etckeeper init

Software

For (un)installing software use apt, apt-get, or aptitude:

  • aptitude: Needs to be installed, but provide more support and some more user-friendly features.
  • apt: A nicer interface than apt-get that is apparently recommended over apt-get, but maybe can't do all the little things apt-get can.
  • apt-get: The low level too. I heard that apt-get apparently has better dependency resolution than apt, but I cannot find this reference now.

These all use dpkg under the hood to do the actual installation. The latter is also useful if you want to see what is installed (see below). The list of sources is in /etc/apt/sources.list which may need to be updated.

I created a user admin for managing software (which is installed in /data). This directory is owned by admin.

sudo adduser admin
sudo mkdir /data
sudo chown admin /data

Now I install conda as follows

su admin
mkdir -p /data/src/
wget http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh /data/src/
bash Miniconda-latest-Linux-x86_64.sh -p /data/apps/conda -b -f
export PATH="/data/apps/conda/bin:$PATH"

I install Mercurial in this root conda environment so I can also install a few other tools with pip:

su admin
export PATH="/data/apps/conda/bin:$PATH"
conda install mercurial
conda update -y --all
pip install hg-git python-hglib
hg clone https://bitbucket.org/marmoute/mutable-history -u stable /data/src/hg/mutable-history
pip install /data/src/hg/mutable-history

Now create the environments

su admin
export PATH="/data/apps/conda/bin:$PATH"
conda env create mforbes/work

module load cuda  # See below - install cuda and the module files first
for _e in work; 
  do . activate $_e
  pip install pycuda \
              scikit-cuda
done

Modules

I manage the software with modules. In particular, I provide the conda modulefile.

Note: Ubuntu also has update-alternatives. see here: https://askubuntu.com/a/26518

Users and Groups

To list groups:

$ groups
mforbes adm cdrom sudo dip plugdev lpadmin sambashare students

Details about who belongs to which group can be found in the file /etc/group.

To create new users:

  • sudo useradd -m <name>: The -m option creates their home directory.
  • Give the user a unique port in /etc/nbports for them to use when running jupyter.

To create a new group:

  • sudo addgroup students

To add users to a group:

  • sudo usermod -a -G students <name>

To make a shared directory for a group:

sudo mkdir /data/shared
sudo mkdir /data2/shared
sudo chown :students -R /data/shared
sudo chmod a-rwx,g+rwsX -R /data/shared
sudo chown :students -R /data2/shared
sudo chmod a-rwx,g+rwsX -R /data2/shared

Similarly, to make user folders, but which are not shared by default:

sudo mkdir /data/users
sudo mkdir /data2/users
sudo chown :students -R /data/users
sudo chmod a-rwx,g+rwx -R /data/users
sudo chown :students -R /data2/users
sudo chmod a-rwx,g+rwx -R /data2/users

Notes: Users need to log out and log back in to enable these permissions to become effective. The +X here sets execute permision for directories but not files. The +s will cause users who make new files etc. to create them from the appropriate group.*

Update Kernel

The recommended way to update your kernel is:

do-release-upgrade

During the upgrade to, I was asked to choose between LightDM and SDDM. I chose the former.

Difficulties

Apparently, upgrading your release is difficult. The recommended do-release-upgrade command only works in certain cases while the end version is current.

If you run into difficulties, here is a more systematic way to proceed. I was having difficulty because my release was not supported. I am following the discussion here to upgrade from 18.10 to 20.04LTS:

$ sudo do-release-upgrade 
Checking for a new Ubuntu release
Your Ubuntu release is not supported anymore.
For upgrade information, please visit:
http://www.ubuntu.com/releaseendoflife
...
An upgrade from 'cosmic' to 'eoan' is not supported with this tool.

Note eoan is 19.10 which I don't want. See Ubuntu Releases for the name you want. I want 20.04LTS which is called focal fossa.

  1. (optional) Backup:
$ screen -S Backup

    $ sudo rm -i /boot/*22*

After this, I did a cleanup:

$ sudo apt autoremove

This removed some important packages, so I reinstalled them after. Then rebooted.

$ sudo shutdown -r now

After this was done, I was still getting an incorrect MOTD and had to remove the cached file:

$ sudo rm /var/lib/ubuntu-release-upgrader/release-upgrade-available

Old

I used the following notes to upgrade 2 Ways to Upgrade From Ubuntu 18.04 To 18.10:

sudo apt update && sudo apt dist-upgrade
sudo vi /etc/update-manager/release-upgrades  # Change Prompt=lts to Prompt=normal
sudo apt install update-manager-core
do-release-upgrade

Note: My /boot partition is small, so I needed to remove old kernels first. Be sure to uninstall the packages rather than just deleting the files.

CUDA

The simplest solution is to use Conda to install the appropriate toolkit:

conda install cupy

This will bring in the best supported version of [CUDA], needed if you want to use CuPy, which does not always support the latest toolkit.

If you need to install it for your operating system, then the next easiest might be

sudo apt-get install nvidia-visual-profiler nvidia-cuda-toolkit

but, this might install an older version of the toolkit though.

You can add the NVIDA repository as:

sudo add-apt-repository ppa:graphics-drivers/ppa

Another option is to try to get the driver directly from Nvidia, but I have found some conflicts with this. Here is my attempt:

I installed the CUDA toolkit as follows as directed on the CUDA Website. Note: you must choose a version compatibile with your kernel corresponding to the table listed there:

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.10
Release:	18.10
Codename:	cosmic
$ uname -a
Linux swan 4.18.0-22-generic #23-Ubuntu SMP Tue Jun 4 20:22:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

This means I have Ubuntu 18.10 with kernel 4.18.0. Follow the instructions on the CUDA Toolkit Download page to figure out which version you should get:

# As of 12 May 2022
# Optional: remove old versions
sudo apt-get purge "^cuda" "^nvidia" "^libnvidia" "^libcuda"
sudo apt-get autoremove

# Optional: Update packages
sudo apt-get update
sudo apt-get upgrade

# Current instructions for 20.04 LTS
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/3bf863cc.pub

# The following adds line sto /etc/apt/sources.list
sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"
sudo apt-get update
sudo apt-get -y install cuda

Older still

Note: CUDA does not work with this by default since it requires ``gcc-4.9``.  See the instructions here:

* http://askubuntu.com/questions/693145/installing-cuda-7-5-toolkit-on-ubuntu-15-10

Here is what I did:

```bash
sudo mkdir -p /opt/compiler_cuda
cd /opt/compiler_cuda
sudo ln -s /usr/bin/gcc-4.9 gcc
sudo ln -s /usr/bin/g++-4.9 g++
sudo ln -s /opt/compiler_cuda/gcc cc

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 50 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9
sudo sh cuda_7.5.18_linux.run --silent --toolkit --override
sudo sh cuda_7.5.18_linux.run --silent --samples --override

Even Older

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1410/x86_64/cuda-repo-ubuntu1410_7.0-28_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1410_7.0-28_amd64.deb
sudo apt-get update
sudo apt-get install cuda

The correct version of GCC etc. were already installed.

Now install the various python tools:

su admin
module load cuda  # See below - install cuda and the module files first
for _e in work2 work3; do
  . activate $_e
  pip install --upgrade ipdb pycuda scikit-cuda
done

Now you can check which version you have:

$ dpkg -s cuda
Package: cuda
Status: install ok installed
Priority: optional
Section: multiverse/devel
Installed-Size: 25
Maintainer: cudatools <[email protected]>
Architecture: amd64
Version: 10.1.168-1
Depends: cuda-10-1 (>= 10.1.168)
Description: CUDA meta-package
 Meta-package containing all the available packages required for native CUDA
 development. Contains the toolkit, samples, driver and documentation.

Daemons

The service wrapper allows you to inspect and control services or daemons such as Docker docker or your HTTP server apache2. This adds entries to /etc/init.d.

sudo service --status-all

Most linux servers are run with systemctl. To see which services are enabled:

systemctl list-unit-files | grep enabled

Config Files

The user's default shell is specified in /etc/passwd and can be set with

sudo usermod --shell /bin/bash mforbes

The default is /bin/bash but /bin/sh might be useful for users such as docker which are intended to run services. To provide a sane initial environment, I define the following initialization files which go in

/etc/profile
/etc/bash.bashrc

These then source files in /etc/profile.d/. One feature of these files is that they look for a .trace file in the user's home directory and show the startup sequence.

$ touch ~/.trace

Upon login, I now see:

$ ssh swan
Welcome to Ubuntu 18.10 (GNU/Linux 4.18.0-22-generic x86_64)
...
Welcome to Swan.

* To debug your startup configuration:
  $ touch ~/.trace    # rm ~/.trace when done
* To run jupyter use the j function:
  $ j MyNotebook.ipynb 
* For detailed instructions run
  $ j --help            # Show port and instructions
* Remember to activate the appropriate conda environment such as
  $ conda activate cugpe2

Usage: j Notebook.ipynb

This will run the notebook with --port ${NBPORT}.
To view this on your laptop, use ssh to forward this port.
I.e. add this to your '~/.ssh/config' file on your laptop:

Host swannb
  HostName swan.physics.wsu.edu
  User ${USER}
  ForwardAgent yes
  LocalForward 10001 localhost:10001
  LocalForward 10002 localhost:10002
  LocalForward 10003 localhost:10003
  LocalForward ${NBPORT} localhost:${NBPORT}
  # The following is for snakeviz
  LocalForward 8080 localhost:8080

If you subsequently connect with 'ssh swannb', then you can 
view the notebook on your laptop at 

http://localhost:${NBPORT}/tree

(but use the link specified by Jupyter as it contains a required
security token.)

Conda Environments
==================
Please create your own conda environments for your work
from an environment.yml file for reproducible computing.
These environments will be stored in ~/.conda/envs/ and
will appear as special Kernels when Jupyter notebooks are
run.  Here is a sample environment.mpl3.yml file that
creates an environment with matplotlib and Python 3:

cat > environment.mpl3.yml <<EOF
name: mpl3
channels:
  - defaults
dependencies:
  - python=3
  - matplotlib
EOF

This can be installed with:
    
    conda env create --file environment.mpl3.yml

Now you can activate it (and should see it as a valid Kernel):
    
    conda activate mpl3
    
This is stored in the following directory:

    ~/.conda/envs/mpl3
    
Simply delete this to remove the environment:
    
    rm -rf ~/.conda/envs/mpl3
    
For more examples see

Conda Environments

In install a base conda environment as the admin user for everyone to use. This is a Python 3 environment with the following packages installed:

  • mercurial: Now supports Python 3 (as of version 5.2)
  • git-annex: Support for archiving large files.
  • nbstripout: Cleaning notebooks - will replace with jupytext soon which needs to be installed in the jupyter environment.
  • argcomplete: Conda tab completion. Add the following to your .bashrc file:
    eval "$(register-python-argcomplete conda)"
  • conda-devenv: Allows including environment.yml files.
  • conda-tree: Allows you to visualize dependenices.
  • conda-verify, conda-build, anaconda-client: Building conda recipes and uploading them to anaconda cloud.
conda deactivate   # Make sure you are in the base environment
conda install python=3 mercurial git-annex \
              nbstripout                   \

Web Server

To host a website I followed the instructions on this page:

To start I just installed apache:

sudo apt-get install apache2

As pointed out in the comments, if you need the full LAMP stack, the configuration process can be simplified:

sudo apt-get update
sudo apt-get install tasksel
sudo tasksel install lamp-server

This points the server to /var/www/html. I then created a personal space:

sudo mkdir /var/www/html/forbes
sudo chown mforbes /var/www/html/forbes
ln -s /var/www/html/forbes ~/www-forbes

The server can be restarted using service:

sudo service apache2 restart

Apache Configuration

The configuration files for Apache are in the following location:

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
`-- sites-enabled
        |-- 000-default.conf
        |-- 000-default-le-ssl.conf
        `*.conf

Let's Encrypt and Certbot

Let's Encrypt uses Certbot as a tool for enabling free site certification. This requires using a supported Ubuntu release.

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository universe
#sudo add-apt-repository ppa:certbot/certbot
sudo apt update
sudo apt install certbot python3-certbot-apache
sudo certbot --apache
#sudo apt-add-repository -r ppa:certbot/certbot

The commented out commands were needed earlier (pre Ubuntu 19.10) but should no longer be needed. Without removing this repo I ran into the following error) during apt update:

E: The repository 'http://ppa.launchpad.net/certbot/certbot/ubuntu focal Release' does not have a Release file.

Once the certificates are created, we might like to make them accessible to other applications like murmerd. To do this, we add the appropriate users (which run the services) to the ssl-cert group and change the permissions of the certificates. I did this following the suggestion here by modifying /etc/letsencrypt/cli.ini.

#/etc/letsencrypt/cli.ini
...
post-hook = chmod 0640 /etc/letsencrypt/archive/*/privkey*.pem && chmod g+rx /etc/letsencrypt/live /etc/letsencrypt/archive && chown -R root:ssl-cert /etc/letsencrypt/live /etc/letsencrypt/archive

To add the user running mumbled to this group:

sudo usermod -a -G ssl-cert mumble-server

To find the user, look in sudo cat /etc/passwd.

References

I would like to be able to host files that can be served by other sites like https://viewer.pyvista.org. This requires enabling cross-origin resource sharing (CORS) which can be done by:

  1. Make sure that mod_headers is loaded:

    sudo a2enmod headers

  2. Adding the Header set Access-Control-Allow-Origin "*" to the appropriate directories in /etc/apached2/mods-enabled/headers.conf or the corresponding /var/www/html/Public/.htaccess file (the former is recommended):

    <!--/etc/apached2/mods-enabled/headers.conf-->
<Directory "/var/www/html/Public">
  Header set Access-Control-Allow-Origin "*"
</Directory>

  3. Checking the configuration and restarting the service:

    sudo apachectl -t
sudo service apache2 reload

This allows the following to work for example:

https://viewer.pyvista.org/?fileURL=https://swan.physics.wsu.edu/Public/papers/Mossman_2021/fig1.vtkjs

Version Control Hosting

With BitBucket "sunsetting" their support for Mercurial, we needed to find a new option. Here we explore options for self-hosting.

Kallithea (incomplete)

Kallithea needs a database, so we make a directory for this in /data/kalithea and store it there.

sudo apt-get install npm
su admin
sudo apt-get install build-essential git python-pip python-virtualenv libffi-dev python-dev
hg clone https://kallithea-scm.org/repos/kallithea
cd kallithea
conda create -n kallithea python=2
conda activate kallithea
pip install --upgrade .
mkdir -p "${CONDA_PREFIX}/etc/conda/activate.d"
echo "export LC_ALL='C.UTF-8'" >> "${CONDA_PREFIX}/etc/conda/activate.d/env_vars.sh"

su admin
conda activate kallithea
mkdir /data/kallithea
cd /data/kallithea
kallithea-cli config-create my.ini
kallithea-cli db-create -c my.ini  #Created with root path `/data/kallithea`, user `mforbes` etc.
kallithea-cli front-end-build
gearbox serve -c my.ini

This runs Kallithea on port 5000 which could be accessed by users with ssh tunelling.

Heptapod

Another alternative is Heptapod. This is a mercurial interface to a friendly fork of GitLab CE intended to ultimately bring mercurial support to GitLab. This can be installed with Docker as discussed below.

As of 1 July 2020: This is my primary alternative to Bitbucket hosted as discussed below. We will probably ultimately host this on an AWS instance.

As of 14 March 2020:

Docker

Several packages (such as Heptapod and CoCalc) require a rather complete system, so are easiest to install using Docker containers. Here we discuss how to set these up. We are using Rootless mode which seems to work well and prevents the need for providing docker with root access.

Note: Be sure to completely purge any previous root-enabled version of Docker before proceeding.

ssh swan
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install uidmap
sudo apt-get purge docker docker.io  # Remove old root-version of docker.
sudo apt-get autoremove --purge

sudo useradd -m docker
sudo usermod -aG sudo docker         # Enable sudo for docker.
sudo su docker
chsh -s /bin/bash
bash
curl -fsSL https://get.docker.com/rootless | sh

This allows the docker user to add processes to start services that will start at login.

sudo loginctl enable-linger docker
systemctl --user start docker

Add the appropriate environmental variables to ~docker/.bashrc:

...
# Docker install (rootless)
export PATH=/home/docker/bin:$PATH
export DOCKER_HOST=unix:///run/user/1017/docker.sock

Docker Cheatsheet

Here are some useful commands:

  • docker pull: Pulls an image.
  • docker create: Creates a container from an image.
  • docker start: Starts running a container.
  • docker stop: Stops ...
  • docker attach: Attach to a running container.
  • docker ps -a: List all containers (both running and stopped).
  • docker images: List all images.
  • docker rm: Remove a container.
  • docker rmi: Remove an image.
  • docker inspect: Lots of information about a container.
  • docker exec -it <name> /bin/bash: Connect to the specified container and run bash (like ssh-ing into the VM).

These appear in documentation, but I do not use them:

  • docker run: This is equivalent to docker create + docker start + docker attach. This can only be executed once. After the container is created, one cannot use subsequent calls to run to change, for example, port assignments. It is probably most useful for short foreground processes in conjunction with the --rm option.

Issues: I originally had a bunch of errors because of interference with the previously installed docker version (not rootless). These went away once I did sudo apt-get purge docker docker.io.

  • Aborting because rootful Docker is running and accessible. Set FORCE_ROOTLESS_INSTALL=1 to ignore.
  • Failed to start docker.service: Unit docker.socket failed to load: No such file or directory.

So I stopped the root docker service (from a previous install) and removed this file:

sudo service docker stop
sudo systemctl disable docker
sudo apt-get remove docker 
#sudo rm /var/run/docker.sock /lib/systemd/system/docker.service

After resolving these issues, I was having the following issue when trying to run the server with systemctl:

$ systemctl --user start docker
$ docker run hello-world
docker: Cannot connect to the Docker daemon at unix:///tmp/docker-1017/docker.sock. Is the docker daemon running?.
See 'docker run --help'.

Heptapod

Heptapod is a service providing Mercurial access to GitLab CE. When running the public server, we host it here:

Here we describe how to run Heptapod in a Docker container. This is a service based on GitLab CE that provides a backend with issue tracking etc. for Mercurial. As above, I have created a docker user account on swan. First I login to this, then make some directories for the server data in /data2/docker/heptapod. Then I pull the docker image.

ssh docker@swan                         # Login to swan as docker
echo 'export GITLAB_HOME="${HOME}/srv/heptapod' >> ~/.bashrc
sudo mkdir -p /data2/docker             # Make the data directory for docker
sudo chown docker /data2/docker         # Change owner...
sudo chmod a-wrx,u+rwxs /data2/docker   # ...and give appropriate permissions
mkdir -p /data2/docker/heptapod         # Now create the heptapod directory.
sudo ln -s /data2/docker/heptapod /srv/ # Link it to /srv/heptapod...
ln -s /data2/docker ~docker/srv         # ...and to the docker home directory.

Now we pull the heptapod image and start a couple of containers:

  • heptapod-local: Only listens on local ports. To use this, users must login with ssh and forward ports appropriately so they can connect (see below).
  • heptapod-public: Listens on public ports. This exposes Heptapod to the world, which may be a security risk. We do this to allow "weak" collaborators access, or to enable transferring repositories from Bitbucket.
docker pull octobus/heptapod
docker create                                            \
       --name heptapod-local                             \
       --restart always                                  \
       --hostname localhost                              \
       --publish 127.0.0.1:11080:80                       \
       --publish 127.0.0.1:11443:443                      \
       --publish 127.0.0.1:11022:22                       \
       --volume ${GITLAB_HOME}/config:/etc/gitlab        \
       --volume ${GITLAB_HOME}/logs:/var/log/gitlab      \
       --volume ${GITLAB_HOME}/data:/var/opt/gitlab      \
       octobus/heptapod

docker create                                            \
       --name heptapod-public                            \
       --restart always                                  \
       --hostname swan.physics.wsu.edu                   \
       --publish 11080:80                                 \
       --publish 11443:443                                \
       --publish 11022:22                                 \
       --volume ${GITLAB_HOME}/config:/etc/gitlab        \
       --volume ${GITLAB_HOME}/logs:/var/log/gitlab      \
       --volume ${GITLAB_HOME}/data:/var/opt/gitlab      \
       octobus/heptapod

Now we can run whichever one we want:

docker start heptapod-local       # Use this in general.
#docker start heptapod-public      # Use this when needed.

Once started, I initialized a mercurial repository in the configuration directory so I can keep track of configuration changes:

cd ~/srv/heptapod
# For some reason, the following file is given rw permission only
# for the user in the docker image, so we can't back it up...
sudo chgrp docker config/heptapod.hgrc
sudo chmod g+rw config/heptapod.hgrc
hg init
cat > .hgignore <<EOF
syntax: glob

data/
logs/
EOF
hg add
hg com -m "Initial commit"

Debugging

Look at the current logs with the following:

docker exec -it heptapod-public gitlab-ctl tail

Heptapod Backup (incomplete) 

docker exec -t heptapod-public gitlab-backup create

This will put a file on the image which we exported:

  • /var/opt/gitlab/backups/1593678341_2020_07_02_12.10.11_gitlab_backup.tar
  • ~/srv/data/backups/1593678341_2020_07_02_12.10.11_gitlab_backup.tar

Optionally, the backup program can upload this to a remote storage location.

Another option is to backup the repositories, I use rclone to copy these to my Google Drive to a remote called gwsu_backups from my docker account on swan using the root_folder_id corresponding to a folder My Drive/backups/RClone/swan/repo_backup.

screen -S RCloneBackup
rclone sync -Pl repo_backups gwsu_backups:

HTTP Redirect

Note: SSL does not yet work with non-standard ports... so I am using HTTP only. I have randomly chosen ports 11080, 11443 and 11022 for HTTP, HTTPS, and SSH access. These are not very memorable, so it would be nice to redirect https://swan.physics.wsu.edu/heptapod to https://swan.physics.wsu.edu:11443. To do this, we simply add a Redirect /heptapod https://swan.physics.wsu.edu:11443/ statement to one of the Apache config files:

#/etc/apache2/sites-enabled/000-default.conf 
<Virtualhost *:80>
    ...
    Redirect /heptapod http://swan.physics.wsu.edu:11080/
    Redirect /discourse http://swan.physics.wsu.edu:10080/    
</VirtualHost>

#/etc/apache2/sites-enabled/000-default-le-ssl.conf 
<Virtualhost *:443>
    ...
    Redirect /heptapod https://swan.physics.wsu.edu:11443/
    Redirect /discourse https://swan.physics.wsu.edu:10443/    
</VirtualHost>

Don't forget to restart the server:

sudo service apache2 restart

Bitbucket Import

  1. Enable OAuth2 integration on Bitbucket. I used my public settings http://swan.physics.wsu.edu/heptapod/users/sign_in.

Note: I had issues resulting in redirect_uri issue because I was using my alias http://swan.physics.wsu.edu/heptapod/users/auth but in my configuration, I used the http://swan.physics.wsu.edu:9080/users/auth form. If you look at the URL sent, it includes the redirect_uri which must match.

  1. Edit the /etc/gitlab/gitlab.rb file on the server. Since we mapped /etc/gitlab to ~docker/srv/config, we can edit it there without connecting.
vi ~docker/srv/heptapod/config/gitlab.rb

#/etc/gitlab/gitlab.rb
gitlab_rails['omniauth_enabled'] = true
...
gitlab_rails['omniauth_providers'] = [
  {
    "name" => "bitbucket",
    "app_id" => "Rc...",
    "app_secret" => "hA...",
    "url" => "https://bitbucket.org/",
  }
]
  1. Start the public server, or reconfigure GitLab:
ssh docker@swan
docker start heptapod-public

or

docker exec -it heptapod-public gitlab-ctl reconfigure
  1. Register for an account on our Heptapod instance.
  2. Login.
  3. Import new project from Bitbucket Cloud.

Issues

  • Some imports are broken.
  • Cloning links are incorrect: http://swan.physics.wsu.edu/mforbes/mmfutils mmfutils_heptapod. Probably need to update the hostname to include the port and/or the /heptapode alias.
  • Cloning from http://swan.physics.wsu.edu:9080/mforbes/mmfutils mmfutils_heptapod does not work.
  • Cloning from ssh://[email protected]:9022/mforbes/mmfutils works on swan but not from outside.
  • Cloning from ssh://git@localhost:9022/mforbes/mmfutils works with SSH tunnel.

Discourse 

ssh docker@swan
mkdir repositories
cd repositories
git clone https://github.com/discourse/discourse_docker.git
cd discourse_docker

Edit the generated containers/app.yml file. I am trying to use Gmail with a custom alias [email protected] which I registered under my Gmail account settings.

DISCOURSE_DEVELOPER_EMAILS: '[email protected]'
  DISCOURSE_SMTP_ADDRESS: in-v3.mailjet.com
  DISCOURSE_SMTP_USER_NAME: ******
  DISCOURSE_SMTP_PASSWORD: *********

## The Docker container is stateless; all data is stored in /shared
volumes:
  - volume:
      host: /home/docker/srv/discourse/shared/standalone
      guest: /shared
  - volume:
      host: /home/docker/srv/discourse/shared/standalone/log/var-log
      guest: /var/log

...
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  - exec: rails r "SiteSetting.notification_email='[email protected]'"

Mailjet: I managed to

Notes:

  • I could not use [email protected] as the SMTP user here since I cannot login to gmail with this.
  • Gmail did not work: probably have to use an App password since two-factor authentication is enabled.
  • I had to use an absolute path for the host /home/docker: ~ did not work.
  • I also tried using Mailjet with - exec: rails r "SiteSetting.notification_email='[email protected]'" but this did not seem to activate either (I was expecting Mailjet to send me an activation email to make sure...)

After editing these, I was able to continue after making these directories:

rm -rf ~/srv/discourse
mkdir ~/srv/discourse

./launcher rebuild app

Not Working: Discourse is running, but not able to send emails.

HTTP Redirect

I have randomly chosen ports 10080 and 10433 for HTTP and HTTPS access. These are not very memorable, so it would be nice to redirect https://swan.physics.wsu.edu/discourse to https://swan.physics.wsu.edu:10443. To do this, we simply add a Redirect /discourse https://swan.physics.wsu.edu:10443/ statement to one of the Apache config files:

#/etc/apache2/sites-enabled/000-default.conf 
<Virtualhost *:443>
    ...
    Redirect /heptapod https://swan.physics.wsu.edu:11443/
    Redirect /discourse https://swan.physics.wsu.edu:10443/    
</VirtualHost>

CoCalc

CoCalc can also be installed with docker. I created the images with the following file:

#!/bin/bash
# initialize_cocalc.sh
docker create                                            \
       --name cocalc-local                               \
       --restart always                                  \
       --hostname localhost                              \
       --publish 127.0.0.1:9443:443                      \
       --volume ~/srv/cocalc:/projects                   \
       sagemathinc/cocalc

docker create                                            \
       --name cocalc-public                              \
       --restart always                                  \
       --hostname localhost                              \
       --publish 9443:443                                \
       --volume ~/srv/cocalc:/projects                   \
       sagemathinc/cocalc

These listen on port 9443. Note: you must connect with https://localhost:9443, not with HTTP.

Issues

New project stuck on "Loading..."

Nextcloud (incomplete)

Open source replacement for Google Cloud etc. There is a docker image.

Incomplete because this needs MySQL etc. and I don't want to figure this out yet.

ssh swandocker

AWS Command Line

Related to docker: if you need to build images for deployment on AWS, you will need the aws-cli:

su admin
sudo apt-get update
sudo aptitude install awscli

Partition Scheme

There are some important partitions and issues related to choice of partitions.

  • /boot: This is where the kernel lives. I originally made it 256MB, but then ran into issues when upgrading the kernel because I did not have enough space to download the new kernel while keeping the old kernel. I recommend using 512MB or 1GB if you have space instead so you can keep a few backup kernels. See What is the recommended size for a linux boot partitiona? for a discussion.
  • /: This is the root partition for the OS. It is where all of the operating system files get installed.
  • /swap: Ubuntu recommends that you include a swap partition that matches your RAM, but it seems that this recommendation is for systems that need to hibernate. For a desktop, swap files might be better since they can grow.

Installing a New Drive

I installed a new internal hardddive and decided on the following partition scheme:

  • /boot: 1GB. I intend to use this to tryout OS upgrades and so that this drive can be used as a bootable backup.
  • /mnt/hdclone: 256GB. Intended to be a backup clone of the internal harddive with the OS and home directories.
  • /mnt/data2: Remaining data partition.

To do this I first ran parted and created the partitions. Then ran mkfs.ext4 to format the partitions:

  1. Identify the appropriate disk
$ sudo fdisk -l
Disk /dev/sda: 238.5 GiB, 256060514304 bytes, 500118192 sectors
...
Device     Boot  Start       End   Sectors   Size Id Type
/dev/sda1  *      2048    499711    497664   243M 83 Linux
/dev/sda2       501758 500117503 499615746 238.2G  5 Extended
/dev/sda5       501760 500117503 499615744 238.2G 8e Linux LVM
...

Disk /dev/sdb: 5.5 TiB, 6001175126016 bytes, 11721045168 sectors
...

Here we see the two internal drives: the original 256G drive /dev/sda and the new 6TB drive /dev/sdb. (Other drives are also listed but have been omitted.)

  1. Create the partitions
$ sudo parted /dev/sdb

Remote Drives (NFS etc.)

Backup

One should always create backups of one's computer. This includes backups of the data and bootable backups. Here are some options.

OneDrive Free Client (incomplete)

This client is like Dropbox but integrates with OneDrive. It is currently approved for use at WSU.

sudo aptitude install -y libcurl4-openssl-dev libsqlite3-dev
sudo snap install --classic dmd && sudo snap install --classic dub
su admin
. /etc/profiled         # Path to /snap/bin set here: needed for dmd
cd ~/repositories
git clone https://github.com/skilion/onedrive.git
cd onedrive
make
sudo make install

This installs the following files:

install -D onedrive /usr/local/bin/onedrive
install -D -m 644 onedrive.service /usr/lib/systemd/user/onedrive.service

Users then configure it as follows:

mkdir -p ~/.config/onedrive
cp ~admin/repositories/onedrive/config ~/.config/onedrive/config
mkdir ~/data2/OneDriveSync
ln -s ~/data2/OneDriveSync/ OneDrive
echo > ~/.config/onedrive/sync_list <<EOF
OneDriveSync/
EOF

This makes a shared folder in my home directory to ~/OneDrive (which is the default configuration in ~/.config/onedrive/config. At this point, one should apparently be able to sync with a command like onedrive --resync. This appears to work, but ends up just returning a blank webpage rather than an appropriate "response uri":

$ onedrive --resync
Authorize this app visiting:

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=22c49a0d-d21c-4792-aed1-8f163c982546&scope=files.readwrite%20files.readwrite.all%20offline_access&response_type=code&redirect_uri=https://login.microsoftonline.com/common/oauth2/nativeclient

Enter the response uri:

Duply/Duplicity

Duply is a frontend to Duplicity, which is recommended here.

TL;DR

  • Identify your partitions and drives.
    sudo fdisk -l
  • Copy:
    sudo rsync -vaxhWE --no-compress --progress --delete --ignore-errors / /mnt/data2/swan_backup/14Mar2020

To partition the hard drives, you can use fdisk.

Timeshift (incomplete)

Timeshift: is a GUI application for backuping system files (only the OS). Does not seem to work headless.

sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install timeshift

Mounting External Drives 

sudo mkdir -p /mnt/Khalids_usb_drive
sudo mount -t ntfs /dev/sdb1 /mnt/Khalids_usb_drive
sudo mkdir -p /data/external_data
sudo mount -t ext4 /dev/sdc5 /data/external_data/

Duplicity (incomplete)

Duplicity is a command-line backup tool that works with Google Drive and Onedrive (though probably not without enable apps for the latter). If you want a GUI front-end, install Déjà-Dup.

  • Enable a Google Drive API app.

    • Log in to console.developers.google.com with the appropriate account.
    • Create a new project. (I called mine Duplicity Backup.)
    • Select and Enable the Google Drive API.
    • Create Credentials:
      • Select OAuth client ID from the Create credentials menu. (Do not create a Service account key.)
      • Give your project a name as needed. (I use Duplicity Backup Client.)
      • Copy the credentials.

  • Create a .duplicity configuration directory. I am doing this as the admin user:

    su admin
cd ~
mkdir .duplicity
cd .duplicity
touch ignore
touch credentials

  • Create an appropriate credentials file:

    # Duplicity Credentials file; -*-Shell-script-*-
# dest = ~/.duplicity/credentials  # Keep this as the 2nd line for mmf_init_setup

client_config_backend: settings  
client_config:  
   client_id: xxx.apps.googleusercontent.com
   client_secret: yyyy
save_credentials: True  
save_credentials_backend: file  
save_credentials_file: gdrive.cache  
get_refresh_token: True

  • Install duplicity. I do this with a conda environment:

    yml
# Environment for Duplicity
# dest = ~/.duplicity/environment.yml
name: app_duplicity
channels:
  - defaults
  - conda-forge
dependencies:
  - python
  - setuptools_scm
  - pydrive
  - pip
  - pip:
    - duplicity

    sudo apt-get install librsync-dev
unset CFLAGS
conda env update -f environment.yml --prune

  • Create a backup script. This one backs up my home directory to my google drive.

    #!/bin/bash
# dest = ~/usr/local/bin/duplicity_backup_home  # Keep this as the 2nd line for mmf_init_setup
export GOOGLE_DRIVE_SETTINGS=~/.duplicity/credentials
duplicity --exclude-filelist ~/.duplicity/ignore ~/ gdocs://[email protected]/backups/swan_mforbes_current

  • Run the backup. I do this in a screen session:

    conda run -n app_duplicity duplicity_backup_home

    This will prompt you for a passphrase which will be used to encrypt your data.

RClone

Unlike Duplicity, RClone does not encrypt your data. This has the advantage that you can browse it online, but the disadvantage of lacking privacy. Apparently, Rclone v1.46 supports symlinks by copying them to text files (since Google Drive does not support symlinks).

Cheatsheet

  • rclone config: Configure remotes.
  • rclone listremotes: Show which remotes you have configured.
  • rclone ls <remote>:: List files on remote.
  • rclone sync -Pl <src> <dest>: Make <dest> match <src> changing only <dest>. Preserve/restore symlinks (-l).

Users

  • As a user, configure your backup. Here will copy my home directory ~ to my Google Drive.

    rclone config
    • I used a simple name (since you need to type this): gwsu.
    • For optimal performance, use a Google Application Client Id (see below).
    • I use permision 1, Full access (so rclone ls works).
    • I created a folder and specified the root_folder_id from the last part of the folder URL.

  • Backup:

    screen -R RClone   # Optional, but prevents hangup when you logout
rclone sync -Pl --exclude ~/_trash ~ gwsu:swan/mforbes_current

    The -P flag shows progress, and the -l flag copies symlinks as files with .rclonelink as an extension. These will be restored when you copy back.

  • Restore: (Here I am restoring to /tmp so I don't clobber my actual home directory by mistake!)

    screen -R RClone   # Optional, but prevents hangup when you logout
rclone sync -Pl gwsu:swan/mforbes_current /tmp/restored_home_directory

  • Here is an example of a script I include with a project to sync the contents of a mercurial repo to a team drive:

    # sync_to_google_team_drive.bash
hg clone . /tmp/paper_soc_soliton
rclone sync -Pl --exclude ".hg/**" /tmp/paper_soc_soliton \
         gwsu_EngelsForbesCollaboration:paper_soc_soliton

    This will pull the contents from the drive, allowing you to compare it with the version control.

    # sync_from_google_team_drive.bash
hg clone . /tmp/paper_soc_soliton
rclone sync -Pl --exclude ".hg/**"                 \
  gwsu_EngelsForbesCollaboration:paper_soc_soliton \
                            /tmp/paper_soc_soliton

Performance (Google Application Client Id)

Google limits the rate at which certain applications can query their systems. Since all RClone users share the same application by default, it is strongly encouraged for you to create your own authenticated client rather than using Rclones. Do this by following the instructions below:

Note: I could not do this with my WSU account since it has been disabled, so I had to do this with my personal Google account or my UW account. For Team Drives you do not need to specify the Root ID: it will default to the drive.

This improved my download performance from ~300KB/s to ~3MB/s.

Admin

  • Install for everyone:

    curl https://rclone.org/install.sh | sudo bash

Microsoft Teams

It is a little non-obvious how to connect to a Teams drive. I had to run the rclone authorize "onedrive" command on my Mac where I was authenticated to my teams folder.

$ rclone config
...
name> mswsu_Phys521
...
Storage> onedrive
...  # Blank client_id and client_secret. No advanced config.
Remote config...
y/n> n
For this to work, you will need rclone available on a machine that has a web browser available.
Execute the following on your machine:
    rclone authorize "onedrive"
Then paste the result below:          # Not sure when this will expire with MFA
result> {"access_token":"eyJ0eXAiO...","expiry":"2021-04-21T11:47:35.052577-07:00"}
Choose a number from below, or type in an existing value
 1 / OneDrive Personal or Business
   \ "onedrive"
 2 / Root Sharepoint site
   \ "sharepoint"
 3 / Type in driveID
   \ "driveid"
 4 / Type in SiteID
   \ "siteid"
 5 / Search a Sharepoint site
   \ "search"

Network

To test connectivity, making a little echo server can be useful. This can be done with the netcat utility:

(server) $ nc -l 12345
(client) $ nc -c swan.physics.wsu.edu 12345

Now you can type on one or the other and should see messages if they are connected.

nc -l -p 2000 -c 'xargs -n1 echo'. Differences in versions (traditional vs BSD) make these solutions fragile (they don't work with the default versions installed in Ubuntu for example). Another answer demonstrates how to do this with socat:

socat TCP4-LISTEN:12345,fork EXEC:cat

Installing ncat, you can make a server that will accept multiple connections:

ncat -l 2000 -k -c 'xargs -n1 echo'

Fail2Ban

The fail2ban package implements a rather draconian policy of banning IP's that fail to authenticate properly. This greatly improves security by limiting the ability of hackers from brute-force trying to break in if users have not used secure passwords.

Unlocking

If a legitimate user accidentally triggers a ban, they can either wait, or an admin and unban them with the following commands:

fail2ban-client status  # See if anyone is banned, and get the jailname
fail2ban-client set <jailname> unbanip <ipaddress>  # Unban them

You will need to know the IP address of the person attempting to login. They can find this with ip a or ifconfig -a or similar. You can also look on the server with iptables -n -L.

Example

As an example, I trigger a ban here from our cluster called kamiak:

(kamiak)$ ssh [email protected]
[email protected]'s password: 
Permission denied, please try again.
[email protected]'s password: 
Permission denied, please try again.
...  # Repeat until ban is triggered
(kamiak)$ ssh [email protected]   # Now connections are refused
ssh: connect to host swan.physics.wsu.edu port 22: Connection refused

Check to see if a ban is in effect:

(swan)$ sudo iptables -n -L
...
Chain f2b-sshd (1 references)
target     prot opt source               destination         
REJECT     all  --  198.17.13.7          0.0.0.0/0            reject-with icmp-port-unreachable
...

See if 198.17.13.7 is our server (kamiak).

(kamiak)$ ip a 
... inet 198.17.13.7...

It is. Check which jail - should be the sshd jail:

(swan)$ sudo fail2ban-client status
Status
|- Number of jail:	1
`- Jail list:	sshd

Okay, now unban.

(swan)$ sudo fail2ban-client set sshd unbanip 198.17.13.7
1
(swan)$ sudo iptables -n -L
...
Chain f2b-sshd (1 references)
target     prot opt source               destination         
RETURN     all  --  0.0.0.0/0            0.0.0.0/0

git clone ssh://[email protected]/gabrielw/cold-atoms.git ~/repositories/WSLDA_cold-atoms

Mumble/Murmer

Mumble is an open source, low latency, high quality voice chat application, but needs a server running somewhere (called murmer). Here we install muble:

ssh swandocker
sudo add-apt-repository ppa:mumble/release
sudo apt-get update
sudo aptitude install mumble-server
sudo dpkg-reconfigure mumble-server

As discussed above, I added the user mumble-server to the ssl-cert group so that it can use the Let's Encrypt certificates. In the end, I have the following active lines in /etc/mumble-server.ini:

Remote VNC

Running applications over X11 is painful if your network is slow. Remote desktop control with Tiger VNC provides a much better experience in most cases. This can be installed with:

sudo aptitude install tigervnc-standalone-server tigervnc-common

Then I created a password and set my configuration to listen locally:

vncpasswd

This will be the password you give to your VNC Client to connect. (Note: I think it should be possible to run without a password but my Mac OS X VNC client does not seem to work without one.)

Now create a ~/.vnc/config file:

# VNC Server config file; -*-Shell-script-*-

Finally, ssh into your computer, forwarding port 5901:

# ~/.ssh/config
...
Host swanvnc
  Compression yes
  LocalForward 5901 localhost:5901
...

and start the server. Here I am running firefox:

ssh swanvnc    # Forwards port 5901
tigervncserver -xstartup firefox

On my Mac, I then connect with:

(Mac OS X)$ open vnc://localhost:5901

Eventually, I kill my server:

tigervncserver -kill :*

Disks

Here is my working /etc/fstab. Note:

  • Use UUID's as listed by blkid since /dev/sd* values may change from run to run depending on how the devices are detected.
  • Make sure that the USB drives have nofail so they do not halt the boot process if they are missing.
# /etc/fstab: static file system information.
# 
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Issues

22 Mar 2020: "failed to connect to lvmetad"

After upgrading the 18.10 kernel (Linux 4.18.0-25), the computer failed to reboot with the error message "failed to connect to lvmetad". Some searching suggested that the NVIDIA drivers might be an issue, so I tried removing them. sudo apt-get purge nvidia-* This did not help.

To debug this, I removed the splash screen and quiet option from grub by changing the following in /etc/default/grub:

# /etc/default/grub
...
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT=""

then: sudo update-grub.

After inspecting the logs, I noticed that there we issues with trying to mount the new disk and it turns out that the PARTUID's I had in /etc/fstab were incorrect. These are now fixed.
