Problem in DHCP Server no free leases Error

[Rajiv Rajaian]

Hi Simon

In my dhcp server the dhcp version was (OS: Scientific linux 4.0)
[root at g40 ~]# rpm -q dhcp
dhcp-3.0.1-12_EL.i386


In my dhcp client , the dhcp version was (OS: Fedora Core 4 )

[root at g152 ~]# rpm -q dhcp
dhcp-3.0.2-34.FC4

Is there anything causing trouble with these versions..


Thanks/Regards
Rajiv
