• For logins use an ssh client, for example putty.exe.
• For file transfer use an sftp client, for example winscp.exe.

To connect from Linux, you can simply use the ssh command for an interactive connection, and the sftp command for file transfer.

   $ ssh gul3.bim.gantep.edu.tr

   $ sftp gul3.bim.gantep.edu.tr

Sending graphical displays from Gul3 to your office PC
To send graphical (X11) displays to your office computer, first you need an X-server to be running on your PC, and then you need to use the X11 forwarding feature of your ssh client.

X Server
The X server accepts graphical data from the remote host and presents it on your desktop.

• If you are using Unix/Linux then you will already have an X server running (you might need to configure its security settings to allow displays from remote hosts).

• For Windows, xdeep seems to be a good choice for an X-server: http://pfs.gantep.edu.tr/windows/X-server/

X11 Forwarding
Once you have an X server running, you need to enable X11 forwarding in your ssh client:

• For Linux/Unix switch on X11 forwarding with the -X option when you connect to Gul3, any X11 output will be automatically forwarded through your ssh connection to your local X server. (there is no need to set the DISPLAY variable).

       $ ssh -X username@gul3.bim.gantep.edu.tr

  You can also add data compression with the -C option if you have a slow connection.

• For Windows using the putty client, enable X11 forwarding in the Connection-SSH-Tunnels menu.
