You can check with netstat: $ sudo netstat -n4lp|grep ':67 ' udp 0 0 0.0.0.0:67 0.0.0.0:* 22466/dhcpd On my system, there's a /proc/net/udp which carries this information. Everything's in hex, so port 67 is shown as 0043: $ grep :0043 /proc/net/udp 5755: 00000000:0043 00000000:0000 07 00000000:00000000 00:00000000 00000000 0 0 8334454 2 ffff880403e60b40 0 You'd have to check your own system to know what's truly reliable and worth using.
