After the transfer you can add the path to the private part of the key to the session preferences inside x2goclient. x2goclient should now establish the connection without asking for a password by simply clicking on the session card view. | After the transfer you can add the path to the private part of the key to the session preferences inside x2goclient. x2goclient should now establish the connection without asking for a password by simply clicking on the session card view. | ||

+ | Start a command prompt and navigate to the x2goclient folder, in this example it is **C: | ||
+ | |||
+ | First we generate a DSA key pair (use an empty password phrase if you want SSO): | ||
+ | <code dos> | ||
+ | C:\Program Files\x2goclient> | ||
+ | </ | ||
+ | |||
+ | :!: ssh-keygen.exe prints the path to the key file(s), you will need that in the next step. | ||
+ | |||
+ | You'll need to transfer the public key file to the wanted server. You can do this using the scp.exe command with the path that ssh-keygen.exe printed (make sure you transfer the id_dsa**.pub** file): | ||
+ | |||
+ | <code dos> | ||
+ | C:\Program Files\x2goclient> | ||
+ | </ | ||
+ | |||
+ | When the file has been transferred, | ||
+ | <code dos> | ||
+ | C:\Program Files\x2goclient> | ||
+ | </ | ||
+ | |||
+ | Go to your .ssh folder, add the contents of the public key file to your authorized_keys file and then remove the public key file: | ||
+ | <code bash> | ||
+ | cd ~/.ssh | ||
+ | cat id_dsa.pub >> authorized_keys | ||
+ | rm id_dsa.pub | ||
+ | </ | ||
+ | |||
+ | You can now add the path to the id_dsa file (the private part of the key) to the session preferences inside x2goclient. x2goclient should now establish the connection without asking for a password by simply clicking on the session card view. | ||

+ | You can also create a desktop shortcut which starts the session with the client window hidden; in x2goclient select Session -> " | ||
