This won't work too well if LCP or IPCP fail to negotiate though. > TIA. > --- > Khetan Gajjar (!kg1779) * khetan@iafrica.com ; khetan@os.org.za > http://www.os.org.za/~khetan * Talk/Finger khetan@chain.freebsd.os.org.za > FreeBSD enthusiast * http://www2.za.freebsd.org/ > Stupidest quote heard : Who is this BSD, and why should we free him ? -- Brian <brian@Awfulhak.org> <brian@FreeBSD.org> <http://www.Awfulhak.org>; <brian@OpenBSD.org> Don't _EVER_ lose your sense of humour ! <brian@FreeBSD.org.uk> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
