DHCP Release/Renew

Are there any UNIX commands that will release and renew a DHCP lease? If not, is there a third party utility that would do this?

Depends on which dhcp client you are using -- check the man page for your particular client software. If there is no "renewal" feature built in, you will just have to stop and restart it.

That's true.... use something like dhclient eth0 to acquire an IP address and then you use something like ifconfig eth0 down to release the IP address.

Insert your actual interface for eth0 Smilie

On solaris u can use
ifconfig hme0 dhcp release to release the ip address and the same can be verified using ifconfig -a and the ip address should be and to get the ip address use
ifconfig hme0 dhcp start.

Substitute the apropriate interface name if it is not hme0
