Re: Help on RedHat 7.2

By default, RedHat 7.2 uses gdm, not kdm.
So you should configure gdm.conf file.

I had made all of the changes as suggested in that FAQ but they did not help at all. Any other suggestions would be greatly appreciated.

More information required


If you configured Linux box correctly and xdm is running well, some other reasons might cause the problem. Please check the followings:

  • Network configuration (LAN or ADSL or LAN with a gateway). If your PC and the Linux exist in the same subnet, we can narrow the problem area.
  • Firewall between the PC and Linux.
  • Dual IP addresses in your PC.
  • A private IP is used for your PC and a public one for Linux.
  • Incorrect DNS(Name server) entry. Your PC name should be correctly entered in the name server. You can verify it using "nslookup" command in Linux. Forward and reverse lookup should be consistent.

We hope this could help you.

Re: More information required

The problem was the linux box was reporting a different host name for the client machine than was being reported by the windows client. Both machines were using a DNS server which is on a Win2K advanced server. I just added a host table entry on the linux box for the client, and that corrected the problem. I will have to go investigate what is up whit the DNS.
