[et-mgmt-tools] DHCP Troubleshooting

[Ole Ersoy]

I tried changing the range to 192.168.1.10 - 192.168.1.254.  Same result:

[root at localhost yum.repos.d]# vi /etc/cobbler/dhcp.template (Did the change)
[root at localhost yum.repos.d]# cobbler sync
Shutting down dhcpd:                                       [  OK  ]
Starting dhcpd:                                            [  OK  ]
[root at localhost yum.repos.d]# tail /var/log/messages

Jun  2 14:56:02 localhost dhcpd: DHCPDISCOVER from 00:16:ec:cc:d1:f6 via eth0
Jun  2 14:56:02 localhost dhcpd: DHCPOFFER on 192.168.1.253 to 00:16:ec:cc:d1:f6 via eth0

The client asks, DHCP offers, and the client asks again....weird right?
