[tutorial] ssh tunneling and socks proxy

[Yann.Sagon]

Hi @Erica.Lastufka

Are you connecting with ssh keys and ssh agent?

An important thing is to remove in $HOME/.ssh/ any private key and public key.

See here for more details:

ProxyJump ssh not working on Baobab

No, unfortunately it’s still producing the same error: it requests a password when attempting to connect to an allocation. My Unige password does not work. In this case cpu205 is where I have a job, and the following config in ~/.ssh/config Host baobab HostName login2.baobab.hpc.unige.ch User gercek RequestTTY force Host cpu* Hostname %h User gercek ForwardX11 yes ProxyJump baobab results in a successful proxy jump into baobab but prompts password for gercek@cpu20…

Also, is there a possibility to request the same cpu in launchJupyterLab so that I don’t have to update .ssh/config every time?

This is not the way to go. Instead modify your .ssh/config file as indicated in the previous link.

You may be interested to use JupyterLab from our new openondemand server? No need to use a tunnel at all.
