ppp-on and ip-up are two different things. you use ppp-on to start your ppp connection. /etc/ppp/ip-up is starting automatically by the ppp daemon (pppd) whenever a ppp link comes up. btw, pppd also runs /etc/ppp/ip-down whenever a ppp link goes down. pppd even passes useful arguments to the ip-up/ip-down scripts. i listed these in my last message. common uses for the ip-up script are to: setup routes, ip masquerading, firewalling, ip accounting, login/user accounting, register for dynamic dns (e.g. a .ml.org domain), start sendmail/fetchmail/whatever, swap /etc/resolv.conf for one that works with your ISP, and so on. ip-down is generally used to turn off or undo the stuff done in ip-up...e.g. terminate accounting, shutdown sendmail, etc. > If I had a way to make the ppp-on script wait until the connection was > established before going on past > > exec /usr/sbin/pppd debug lock modem crtscts /dev/ttyS1 38400 \ > asyncmap 20A0000 escape FF kdebug 0 $LOCAL_IP:$REMOTE_IP \ > noipdefault netmask $NETMASK defaultroute connect $DIALER_SCRIPT > > to the rest of the script, I could just put tail in after the line above > and it wouldn't be run until the connection was established (and the > information was in /var/log/messages). this is exactly why the ip-up is there...so you can run things immediately after the ppp link comes up. craig -- craig sanders -- Unsubscribe? mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
