X connection issues with Solaris CDE 1.6

X connection issues with Solaris CDE 1.6

This apparently is a 1.5+ issue that still persists:

I start an X session to connect to a Sun server and it takes 10-15 minutes 
to get the login prompt. I can login OK and can then work within an 
existing xterm session. However, if I try to do anything on the CDE 
desktop, the X session freezes.

I have attached the log file.

Does this mean that the issue has been present since X server 1.5.0?
Or do you mean since Cygwin 1.5?

This is pretty likely to be waiting for something on the host you are trying
to login to.  Google's favourite answer is that host is spending that time
trying to rDNS the address you are connecting from.

The X server doesn't seem to be able to connect to the fontserver you are
pointing it at, so you should be able to drop the -fp option, although I don't
think that can be the cause of the delay.

This X server release was superceded by 1.9.0-2 on 2010-10-23.  The current X
server release is 1.10.0-1.

Your CDE freezing problem sounds a lot like upstream bugs [1] and [2], which I
believe are resolved since 1.9.0, so you might like to try upgrading your X
server.
