If your linux machine is running on a dhcp enabled network , how do you identify the dhcp server name ?
Check out the file /var/run/dhclient-eth0.lease , replace the eth0 with you network interface name . The tag “dhcp-server-identifier” tells you the dhcp server name.
[root@linux-cloud ~]# cat /var/run/dhclient-eth0.lease
lease {
interface “eth0”;
fixed-address 192.170.1.3;
option subnet-mask 255.255.255.0;
option routers 192.170.1.1;
option dhcp-lease-time 86400;
option dhcp-message-type 5;
option domain-name-servers 192.170.1.1;
option dhcp-server-identifier 192.170.1.1;
renew 0 2008/11/23 18:02:45;
rebind 1 2008/11/24 03:55:08;
expire 1 2008/11/24 06:55:08;
}
[root@linux-cloud ~]#
