You can pick up the current sources from ftp://ftp.freebsd.org:/pub/FreeBSD/FreeBSD-current/src/usr.sbin/ppp if you want to have a look at the "current" version, but I don't think it'll compile on 2.1*. If you're interested in *just* the patches, have a look on http://www.freebsd.org/~brian. -- Brian <brian@awfulhak.demon.co.uk> <brian@freebsd.org> <brian@utell.co.uk> <http://www.awfulhak.demon.co.uk>; Don't _EVER_ lose your sense of humour
