Moving from Centos 5.5 to SL Linux 6.1 DHCP does not appear to register itself in DNS. You get a DHCP address but the system will not resolve to the dns name, only IP address. Any Ideas?

Hi, as i understand, there is: 1. SL6 DHCP server (config moved from CentOS 5x?) 2. client(s) wanting to get IP address and DNS IP address to resolve .... what i'd do: 1. check the dhcpd.conf - and see if your DNS server is stated there 2. check the client network setup - /etc/resolv.conf (if it is linux) But anyway, most likely, problem is in the dhcpd.conf. If you'd posted it here, it would help us to see what you have .. cheers, -------------------- |

[here is the contents of resolv.conf
; generated by /sbin/dhclient-script search mayo.edu nameserver ###.###.###.### nameserver ###.###.###.### It wasn't that the system was not getting an address, it was other systems could not resolve its DNS name. I disabled networkmanager and rebooted. On the reboot as su I ran "dhclient -4 -H "myhostname" That forced my DNS name to register and now other systems can resolve my system. It has survived several reboots so I think I am good now. Thanks for your response. If this does not make sense please feel free to comment.
