Perl check dhcp

If you get " No response from server" make sure Nagios Server is in DHCP

byrob2791, August 15, 2021

If you get the error "No response from server", make sure your Nagios server is registered in DHCP (hopefully as a reservation). Even if your linux box is static, you still need to make a reservation for this plugin to work.

Besides that, this plugin works good. You may only request 1 DHCP at a time, so you need to call this plugin multiple times, which means multiple services in Nagios.

This is because this plugin uses perl module Net::DHCP::Watch. A limitation of this module is that the requesting mac address already be in the DHCP server. Module info: https://metacpan.org/pod/Net::DHCP::Watch
