a ssh x11 problem

[Hudson Delbert J Contr 61 CS/SCBN]

is it absolutely neccesary to forward X. i never do so
as any machine i can access via ssh doesnt require X
and i would never do it on some one else's system w/out
permission. its not a harmless connection as the opens the 
for all sorts of keyloggers, addy and connection hijacking
ip stack coding violations and corruption by java and others
like it. its not clever it dangerous if we are talking an enterprise.
i cant think of a single firm of any size that would allow this type
shenanigans.

Hi,

ssh should really be setting the DISPLAY variable for you. To set this up,
check the following items.

/etc/ssh/sshd_config on the remote computer should have the following line
present in it somewhere

X11Forwarding yes

If not, then enter the line in and then run the following command as root to
restart your ssh server (don't worry, it won't kill your running
connection)
/etc/init.d/ssh restart

Next, on your local machine, edit ~/.ssh/config, and make sure it has the
following lines present in it as well.

ForwardX11 yes
Compression yes

The ForwardX11 variable informs ssh to always set up X forwarding. You can
skip this if you like, and just use the -X flag when connecting to a remote
machine ie ssh -X username at remote.machine.com, when you want to forward X.

So, that should have you all up and running. If it's another Ubuntu or
X-based machine that your ssh-ing to, then it all should work. You can
check to see if it's worked by running 'echo $DISPLAY' and it should
respond with something like "localhost:11.0" If it doesn't, then it's
usually because xbase-clients isn't installed on the remote machine (maybe
because it's a server or for some other valid reason)

Hope this help, let us know how you get on.

Regards
Kyle
