If you are using dhclient, you should try:
man dhclient
man dhclient.conf
This will depend on what flavour of Linux you're on, different ones might
not use the ISC client.
Here is a config example which shows how to run a script:
timeout 60;
retry 60;
reboot 10;
select-timeout 5;
initial-interval 2;
reject 192.33.137.209;
interface "ep0" {
send host-name "andare.fugue.com";
send dhcp-client-identifier 1:0:a0:24:ab:fb:9c;
send dhcp-lease-time 3600;
supersede domain-name "fugue.com rc.vix.com home.vix.com";
prepend domain-name-servers 127.0.0.1;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, host-name;
require subnet-mask, domain-name-servers;
script "/etc/dhclient-script";
media "media 10baseT/UTP", "media 10base2/BNC";
}
alias {
interface "ep0";
fixed-address 192.5.5.213;
option subnet-mask 255.255.255.255;
}
Hope that helps!
