[FreeNX-kNX] strange problem with freenx

[Antonis Tsolomitis]

Hello all.

I have a strange problem with freenx.

Everything goes well with nxclient up to the point that says 
"Established X server connection".

It stays there for 30 seconds and then times out.

I have freenx-0.6.0 and nx-2.1.0 (I could not find an rpm of the 0.7 
version of freenx).
System is RHEL5.

I tried to change the DISPLAY=unix:$display in nxnode to localhost:$display
but no luck.

Does anyone knows this problem?

Thank you very much,

Antonis.
