The two DHCPd servers should have different ranges, ie:

DHCP A: 192.168.2.1  - 50
DHCP B: 192.168.2.51 - 99

This isn't an answer, it's a recommendation. – joeqwerty Jul 24 '11 at 18:32

The host that you log in to (I'm assuming you mean "connect to") isn't dependent on the server that you got your DHCP assigned ip address from (unless the server you're connecting to is on another network, in which case the router information that you got from DHCP will determine how your traffic is routed to the destination host), it's dependent on which server answers the ARP query for the ip address that you're connecting to.

Also, many OSes will pickup the duplicate IP and stop using it... – Chris S♦ Jul 22 '11 at 16:39
