I run CentOS 4.1 on a remote server and did a minimal installation. My problem is that I can not login using the HOSTNAME, must use the IP.

1. edited the - /etc/sysconfig/network
2. changed - HOSTNAME=a266
3. restarted the network

Looks ok, hostname appears when logged on via IP, but can't use the HOSTNAME to log on from client.

I can't figure out where I missed out.

In /etc/hosts on host 192.168.0.102 add a line

192.168.0.101 a266.<whatever your domain part is> a266

This said when not running an own DNS. If a name server for the own domain is running, then be sure /etc/resolv.conf has the "search" entry for the domain, to be able to reach the other host by short hostname.

Correct this is a private network, works perfect Thank you Alexander.

The server receives the ip from a router and therefore I'd like to use a host name, since ip can change when rebooting router or server.

That would be the next issue since the 192.168.0.100/200 did not do it.

Do I have to enter all the ip addresses given from router to solve this or is there a one line solution?

Yes, thank you very much Scot. My router could assign static address to the server. I didn't check, believed that it could do one way or the other. Problem solved.:)

Unless your router assigns the same IP address each time you should consider using static addressing. Some routers are able to assign reserved IP addresses to devices based on the MAC address of the network interface in the server.

Without that capability assign static IP addresses then the entries in your /etc/hosts file will always be correct.

For a small home network maintaining /etc/hosts files is not a problem.
