I am trying to remote into the login node using VNC (specifically Real VNC and Ultra VNC). I am using Putty for ssh tunneling. With Real VNC I get "read: connection reset by peer (10054)" after entering my password. With Ulra VNC I get "Write extract: Socket error while writing" I am using "L5901 localhost:5900" as my tunneling parameters for putty. My understanding is that this means that if I VNC into localhost:5901 I will get forwarded to 5900 on the login node. Are there any detailed instructions available for this. Thanks.
