DHCP server


Greetings
Simple question:
How can I check the ip address of the DHCP server from the DHCP client machine?

It depends on the DHCP client you are using. With pump use -s:
Code:
# pump -s 
Device eth0
         IP: 192.168.xxx.yyy
         Netmask: 255.255.255.0
         Broadcast: 192.168.xxx.255
         Network: 192.168.123.0
         Boot server 192.168.xxx.zzz
         Next server 192.168.xxx.zzz
         Gateway: 192.168.xxx.zzz
         Gateways: 192.168.xxx.zzz
         Nameservers: 192.168.xxx.zzz 204.52.135.2

If you're using dhcpcd or dhclient, RT(F)M, I presume they have an equivalent option.

DHCP clients

Start with:
Code:
$ man dhcpcd
BTW, if you don't know what DHCP client you're using, try:
Code:
$ dhc<TAB>
As long as tab completion is working, it will show dhclient or dhcpcd. If it does not complete to either of these, then you probably (99%) have pump.

DHCP client list

Update:

Yesterday I ran across a reference in a mailing list archive to "4 Linux DHCP clients in common use". "4?", I said to myself, "I only know 3, WTF is the 4th?"

I did a variety Gooles, the 1 that worked is:
"linux dhcp clients" dhcpcd dhclient pump

& the 4th is dhcpxd. Notice that dhc<tab> will still detect it. So the list, possibly in chronological order, is:
  • pump
  • dhcpcd
  • dhcpxd
  • dhclient

Notes
SimplyMEPIS now uses dhclient (was pump).

Obviously, I have never seen dhcpxd on a system, since I just heard about it today.

It, dhcpxd, may be a Mandriva creation.
