I've just installed Ubuntu 6.10 and have hit this problem having used System -> Administration -> Networking to configure the modem. /etc/ppp/peers/ppp0 doesn't contain noauth, unlike a much older version of Ubuntu I used to use, probably 5.04. Consequently, pppd complains during `ifup ppp0' as described above. The vanilla 6.10 install has left me with gnome-system-tools 2.15.5-0ubuntu2.
** Changed in: gnome-system-tools (Ubuntu) Status: Needs Info => Confirmed -- [network-admin] creates /etc/ppp/peers/ppp0 without noauth https://launchpad.net/bugs/82378 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
