thanks for the many thoughtful replies, especially Trevor Benson for the detailed list of suggestions. I've everything suggested but still get authentication that times out before a gnome session comes up. I tried scraping things out on the server side, reinstalling, rebooting, make a completely new test user account, restarting the X on the client side. I try to connect to the new account, and still get authenticated but no gnome for centos 5. from the same nxclient I can connect to a centos 4.4 box, and vnc connects fine to centos 5 and gives me a gnome desktop. looks to me like it might be a quirk of the new mac client interacting with the centos 5 nxserver (but not 4.4), based on other folks connecting just fine to centos 5.
there was a note about "known issues" on the wiki, so I also installed the NX client for linux and installing on the server:
rpm -i nxclient-2.1.0-17.i386.rpm
this gives me new stuff in /usr/NX which I also copied to the freenx style directory for good measure and restarted things
cp /usr/NX/bin/nxclient /etc/nxserver/
nxserver --restart
I tried connecting from client, authenticates but no gnome.
the nxclient I am using (mac OS X) I downloaded within the last week, the nomachine site says its release 2.1.0-17. and using this same installation of nxclient on my mac I get a gnome session when connecting to a centos 4.4 box
in case its useful to have more of a play-by-play in the archives, here what I tried:
#on centos 5 server machine, I removed, reinstalled, rebooted:
su
yum remove nx freenx
# the remove succeeds, I do the following for good measure
rm -Rf /etc/nxserver
rm -Rf ~<me>/.nx
reboot
# server comes up
su
yum update
yum install nx freenx
# output looks good, includes:
# Stopping sshd: [ OK ]
# Starting sshd: [ OK ]
# Installed: freenx.i386 0:0.5.0-13.el5.centos nx.i386 0:2.1.0-6.el5.centos
# Complete!
nxserver --adduser me
nxserver --passwd me
# manually copy /etc/nxserver/client.id_dsa.key --> client nxviewer
reboot
# server comes up
nmap -p 1-65535 localhost
# the only open port is
# 22/tcp open ssh
# and I have ssh forwarding enabled, even though it should not make a difference
nxserver --status

# so at this point I try to connect from the client, I get authenticated and then nothing more, times out after a minute
# now I add a new user account to the system, testuser, a completely new account, and add this account to the nx users
nxserver --useradd testuser
# from the client, I try connecting to account testuser, get authenticated, no gnome desktop (or anything else),
# and the connection times out. the error in the client "details" window is
