I've installed x2go (SQLite) with PXE boot and everything looks like it went ok. The server is an HP DL-385 G7 with 16GB ram, 1TB drive and AMD Opteron Model 6128 HE 8 core, 2.0 GHz, 12MB L3 processor. Runing with a Wyse S50 thin client at 100Mbps on a switch directly to the server. The server is doing nothing other than hosting this x2go project. PXE boots and I'm presented with a logon screen but the response is extremely slow. Even as I type in my password the characters are echoed to the screen several seconds after I type them. Nothing ever happens after I enter the password, the screen goes blank and there it sits. I've left it for hours and nothing changes. The nic light blinks like crazy so I watched with tcpdump and posted it below if that helps (sorry about the wrap). Loads of nfs traffic for some reason. Never ending. Not sure where to look at this point. Any help is appreciated.
