Linux and Mac OS X support X Forwarding with no extra software. Any terminal on Linux should do X Forwarding, Mac users need to run " Applications > Utilities > XTerm ". In a command line terminal run " ssh -Y jdoe@compute.example.edu matlab " and you'll be running matlab on " compute.example.edu " but seeing it on your desktop. Windows users need two pieces of software: an secure shell program (ssh) to establish the remote connection and an X Server to handle the local display. Prerequisites Putty  for SSH Xming  for the XServer Configuring Putty Add Unix hostname Switch Protocol to SSH Type name of session in saved sessions Click 'Save' Expand the 'SSH' tab from the 'Category' list Choose 'X1...

Host key verification failed. Solution #1: Remove keys remove the entery from /.ssh/known_hosts and try connecting again. 1.Open up /etc/ssh/sshd_config and set "PermitRootLogin" to "yes". (Your ISP probably set it to "without-password") 2.You also need to restart the sshd process. This is done by killing the existing one (use ps -aux|grep sshd to get the process ID, then use kill to zap it), then restarting /usr/sbin/sshd #################################################### By default, Fedora Core 6 systems come with an old Java software installed...
