-s checks for the IP address of the dhcp server that provided the
response.
e.g. - my dhcp server is 192.168.0.4
[root at calcutta contrib]# ./check_dhcp -s 192.168.0.4 -t 2
DHCP ok: Received 1 DHCPOFFER(s), 1 of 1 requested servers responded, max
lease time = 18000 sec.
[root at calcutta contrib]# ./check_dhcp -s 192.168.0.5 -t 2
DHCP problem: Received 1 DHCPOFFER(s), 0 of 1 requested servers responded,
max lease time = 18000 sec.
