This is why I made sliplogin, pppd and ppp (thanks Brian) generate a file in /var/run which gives the sl/ppp/tun interface of the daemon attached to a particular tty. e.g. /var/run/ttyd0.if contains "ppp0". Since 'w' tells you the tty the user is on (from /var/run/utmp), it is a simple hop to get the sl/ppp/tun interface they are using. /* Daniel O'Callaghan */ /* HiLink Internet <http://www.hilink.com.au/>; danny@hilink.com.au */ /* FreeBSD - works hard, plays hard... danny@freebsd.org */
