Nomachine on RHEL 4/5

nsx241 · 01-04-2010, 07:40 PM

I've installed the latest no machine rpms from nomachine. Status shows that nx server is running:

Code:

[nisong@dadvml0117: ~]$ sudo /usr/NX/bin/nxserver --status
Password:
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.

However, connecting from a windows client, I get the following:

Code:

NX> 203 NXSSH running with pid: 4460
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options

NX> 280 Exiting on signal: 15

So I get past authentication, but it then times out during session download. And here's the output from /var/log/messages on the server:

The only strange thing I've noticed (other than the error messages) is that the log messages for NXServer/NXnode have a date of Jan 5, yet the correct system time should be Jan 4 as seen in the first message.

Any suggestions appreciated. Note this is happening on both my RHEL 4 and RHEL 5 machines.

Some additional info from the nx session file:

Code:

So it looks like it's looking for the "Connected" message for nxnode, but instead it's receiving '?0a' (?) and some other weird characters. What could be causing this? Missing fonts?
