[LUGSB] Remote desktop from SINC site?

[William Joseph Lahti]

I have used X tunneling from SINC site desktops. However, I've never tried 
to connect to a machine that's off-campus (outside sunysb.edu) from a SINC 
site system.

Go to start->programs->Network tools->X-Win32 8.1->X-Win32. You can 
configure your connection from there. Just make sure the other end is 
properly configured.

I should mention the the iMacs that run Linux in the Math SINC site are 
NOT SINC site computers. That half of the room is the "Mathlab", and is 
controlled by the Math department. You need a seperate account to access 
these machines.
