SSH
SSH stands for Secure SHelland is the protocol to send your data over the internet in a safe way. The precursor of SSH, Telnet, was and is more unsafe and that’s why SSH is often used. .
You can log in true SSH on our shell server: shell.nxs.nl
You can use SSH in many ways. We often use PuTTY, a free program which you can download on: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html.
You don’t have to change anything, except the location where you want to want to SSH to. Don’t forget to select the protocol "SSH".
PuTTY
If you open PuTTY you can log in immediately.
You are now logged in. Next you can change some things. We have installed some helpdesks on our server, the so-called editors as stipulated below:
