 +====== PuTTY ======
 +This page explains how to connect to our frontends using [[https://www.chiark.greenend.org.uk/~sgtatham/putty/|PuTTY]].
 +
 +**If you want to use graphical applications on our cluster, PuTTY is not the right choice, please have a look at [[en:services:application_services:high_performance_computing:connect_with_ssh:mobaxterm|MobaXterm]].**
 +
 + ===== Creating an SSH Key with PuTTYgen =====
 +  - Open PuTTYgen
 +  - Click 'Generate' and follow instructions
 +  - Enter a passphrase for the key
 +  - Save private key
 +
 +===== Upload Key =====
 +To upload a key, please log into your account on the [[https://www.gwdg.de|GWDG Website]], go to "My Account". Then scroll down to "Other Settings" and click "edit". You can now add a **public** key. \\
 +You have to use the contents of the top box in PuTTYgen, which is the correctly formatted public key.

 +
 +===== Using PuTTY without Agent (insite GÖNET)=====
 +  - Open PuTTY
 +  - Put in Hostname
 +  - Go to "SSH"
 +  - Select "Auth"
 +  - Browse to your key
 +  - Click Open
 +  - If you secured your key with a passphrase (which we highly recommend), you will be asked to enter it

 +
 +===== Using PuTTY with SSH agent =====
 +If you are outside the [[en:services:network_services:goenet:start|GÖNET]], e.g. not on campus and are not able to connect to the [[en:services:network_services:vpn:start|VPN]], you need to use SSH-Agent forwarding to be able to move from login.gwdg.de to one of our frontends.
