Remote X apps

This is a follow up to my other thread, where I had problems starting X apps remotely after successfully making a PPTP connection to my LAN at work.

After checking everything it seems as though the X client (the app I'm running off my work computer) is able to connect to my X server (the computer on my desk at home). I checked with 'netstat -a' and saw a connection on my x11 port (TCP6000) with the work machine that I 'telnet'ed into. I ran xclock, and didn't get any "Can't open display" messages. However, even though the X client -> server connection is there I still don't see xclock on my screen.

Anyone have any ideas? I thought everything would work given the X client is able to make a connection to my server, yet I don't see the X app.

Thanks for the help!

try invoking xhost + on that server machine so that it will allow connections to it.

That may be a good starting point.

I solved this problem!!! It turned out to be the MTU issue with ppp0. For all those people who encounter the bizzare problem that I had, try setting your MTU for ppp0 lower, to say like 400. My default of 1496 didn't work, giving me headaches until I turned the MTU down, and everything WORKED! You can do this temporarily by doing 'ifconfig mtu xxx ppp0'.

Thank you to Vincent Zweije (author of "Remote X apps mini How-To") for his insight into the problem, it was he who suggested lowering my MTU value. I give him all the credit
