I upgraded to RedHat 9 last weekend and ran into the same problem. Â The server which used to work on RedHat 7.1, did not work on RH9.0
It took me a while, but I figured it out... Â Yes, the server does indeed work on RedHat Linux 9.
Your linux box needs to be running the nscd (name service cache daemon), have a properly configured hostname in /sysconfig/network, and also, your hostname must appear with the appropriate address in /etc/hosts.
That's all. L8r,
