Remote SSH

There is package called Remote Development in VSCode which includes

  • Remote SSH
  • Remote WSL
  • Remote Containers
  • Remote Explorer

Although all might be useful, we try to make use of the first one Remote-SSH. This allows to connect with your locally installed VSCode to connect to a remote environment, offering a shell and access to the file system on that host.

Information on:

Kernel version is too old?

Update 2023

Not relevant anymore. All our servers have been upgraded.

What happens if the server has a too old kernel. We are going to use a singularity container to run a more recent version of node and allow VSCode to use srvx8 as well. It will complain a bit, but work.

Here is how:

  1. Login to srvx8
  2. run /opt/containers/vscode-server/setup.sh
  3. Look inside $HOME/.vscode-server/singularity.bash and make sure that path that you require are available in SINGULARITY_BIND variable. Your Home directory is always available. Other system path are not.
    • Maybe it is necessary to change the user shell of your account to bash. Run chsh -s /bin/bash on remote host (srvx8, ...)
  4. Switch remote.SSH.localServerDownload to off in the Remote SSH package.
  5. Setup a new host in Remote SSH on your VScode and connect to srvx8.

Configure a Python interpreter in VSCode according to the installed module: - SRVX8 : /home/opt/spack/opt/spack/linux-centos6-haswell/gcc-5.3.0/anaconda3-2020.07-opjqtspow2mjqthtdxvx7epz6rntkv2p/bin/python

Updates

Whenever the vscode-server reports an error, it might have happened that it automatically updated and a new version has been installed on the remote host. if so run ~/vscode-server/fix.sh to make the changes to the run scripts. Then it should work again.
