My home RELENG_7 box: # pkg_info | grep dhcp isc-dhcp3-server-3.0.5_2 The ISC Dynamic Host Configuration Protocol server # grep dhcp /etc/group _dhcp:*:65: dhcpd:*:1502: # grep dhcp /etc/passwd _dhcp:*:65:65:dhcp programs:/var/empty:/usr/sbin/nologin dhcpd:*:1502:1502:DHCP Daemon:/nonexistent:/usr/sbin/nologin # ps -auxw | grep dhcp dhcpd 699 0.0 0.1 3088 1756 ??
