External SSH Access to ISIMA/LIMOS Computing Resources✯
To access the computing resources of the IIA and LIMOS via SSH, the following prerequisites must be met:
- Have an account
- Have submitted your public key via the ticket manager
If you are unsure what a public key is, please consult the Public/Private Key Authentication section.
SSH Connection to ext.limos.fr✯
The SSH server is located at ext.limos.fr and listens on port 2225.
Attention
The server ext.limos.fr is not intended for storing your files. You may use it as a temporary zone for a few dozen minutes to transfer data to/from the computing servers.
Connecting from Linux or Mac✯
To establish such a connection on Linux or macOS, you can use the following command:
ssh your_identifier@ext.limos.fr -p 2225
If you wish to connect to Linux resources in graphical mode (X), you can use the command:
ssh -Y your_identifier@ext.limos.fr -p 2225
If you are using a Mac, this assumes you have previously installed XQuartz.
Once connected to the bastion host, you will need to initiate another SSH connection with X forwarding enabled using the command:
ssh -Y your_identifier@final_server
Connecting from Windows✯
You can use PuTTY to connect via SSH from a Windows machine. Ensure the following settings are configured:
- The server address in the field labeled "Host Name (or IP address)"
- The port must be set to 2225 as shown below
- Specify the path to your private key file that corresponds to the public key you previously sent to cri-commun@isima.fr. This setting is found under "Connection/SSH/Auth" and then "Private key file for authentication".
To connect in graphical mode using PuTTY, you must enable X forwarding in the X11 configuration panel of PuTTY. This requires that you have previously installed an X server for Windows. A popular X server for Windows is Xming.
