To run an App, it’s best to have your own resource (see https://icm-institute.atlassian.net/wiki/pages/resumedraft.action?draftId=1358725121). The first step to set up you resource is to connect to a remote server of the UI ( carbonate, bigred3, …).

To connect to the remote system you have to use ssh. When you first try to connect via ssh , you will be asked for your password and then you will be able to copy your public key to your account on the remote system.

To connect via ssh, I write:

$ ssh abussalb@carbonate.uits.iu.edu

but after 2 minutes, I get this error:

ssh: connect to host carbonate.uits.iu.edu port 22: Connection timed out

Meeting with Soichi

  • Test if the version of my OS is the problem

→ Soichi created a virtual machine with my OS and ssh versions and he can connect to the remote system

  • Maybe there is a firewall set up by ICM that prevents me to connect to a computer hosted outside the lab (an egress firewall)

→ ask the IT team at the ICM

  • Maybe there is a firewall internal to my computer

→ ask the IT team at the ICM

  • Try to connect to the remote via my Windows machine

From my Windows machine, when I enable the VPN, I can connect to my remote computer at work via ssh, and it works fine. So, Soichi asked me to enable my VPN and then connect to the remote.

In my command prompt, I run:

ssh abussalb@carbonate.uits.iu.edu

and I was asked for my password, so the problem seems to be the firewall, and it was confirmed by Laurent H.
