I think it's probably revision 1.48 of src/usr.bin/w/w.c that you want. : revision 1.48 : date: 2001/07/26 19:20:13; author: brian; state: Exp; lines: +40 -41 : When -n is specified, don't attempt to turn hostnames found in utmp : into addresses as we have no idea what address family they belong to. : : When -n is not specified, resolve IPv6 as well as IPv4 addresses found : in the host field of utmp. Use realhostname_sa() to resolve addresses : (the old code was wrong). : : Rename ``x'' to ``x_suffix'' to avoid confusion. : : Hard code the host column width to 16 (against the imminent increase : of UT_HOSTSIZE in utmp.h). I don't have a 4.X installation nearby to test this & merge it though :( - Giorgos
