Question about the check_dhcp plugin

[Manuel Michalski]

Hello guys 

 

I have a short question regarding the check_dhcp plugins - have you removed the "Rogue" option? I can't find it inside to check for rogue dhcps:

 

/check_dhcp --help
check_dhcp v2.3.1 (monitoring-plugins 2.3.1)

This plugin tests the availability of DHCP servers on a network.

Usage:
 check_dhcp [-v] [-u] [-s serverip] [-r requestedip] [-t timeout]
                  [-i interface] [-m mac]

Options:
 -h, --help
    Print detailed help screen
 -V, --version
    Print version information
 --extra-opts=[section][@file]
    Read options from an ini file. See
    https://www.monitoring-plugins.org/doc/extra-opts.html
    for usage and examples.
 -v, --verbose
    Show details for command-line debugging (output may be truncated by
    the monitoring system)
 -s, --serverip=IPADDRESS
    IP address of DHCP server that we must hear from
 -r, --requestedip=IPADDRESS
    IP address that should be offered by at least one DHCP server
 -t, --timeout=INTEGER
    Seconds to wait for DHCPOFFER before timeout occurs
 -i, --interface=STRING
    Interface to to use for listening (i.e. eth0)
 -m, --mac=STRING
    MAC address to use in the DHCP request
 -u, --unicast
    Unicast testing: mimic a DHCP relay, requires -s

 

I downloaded the plugins via Git, did an "./configure", "make" and "make install" with no special options on a Debian 11 system. 

 

Thank you for your anwer!
