Do you have a dhcp client and/or server that could be interfering with
this? check_dhcp need either one of the dhcp port open for
communication, and won't work is a daemon is already bound to the port
you're trying to use.
BTW, having a SUID binary world-writable is a bad idea; anyone could cat
another executable into it to gain root access.
