You need to add yourself to the dip group, not the dialout group. The dip group is for those who dialout using pon / pppd. The dialout group is for those who need full access to the raw serial port. And yes, the group naming convention certainly does suck. How it works : If you are in group dip, you have read and execute permission to the /usr/sbin/pppd script, so you can run it. Since the program is setuid-root, it runs with root's priviledges. This allows it to grap the serial port, at which point it drops the priviledges. HTH. -- Regards, Paul
