I am using FC3 on x86_64. Modem is external USB Intracom NetMod ISDN. After spending a looot of time to configure my modem in order to dialout, I managed the following:
* kppp connects fine but no DNS server is found, although /etc/resolv.conf is writeable and kppp writes its temp entries with my actual dns servers! I tried linking /var/run/ppp/resolv.conf to /etc/ppp/peers/resolv.conf but didn't work.
* wvdial works fine, DNS problems solved but it works only as root, which means that I have to open a terminal, su root and then wvdial.
* I overwrite ~/.wvdial.conf with /etc/wvdial.conf and gnome-ppp tries to dialout, but hangs up right after "Dialing 893847283...", and then (obviously overwrites my .wvdial.conf file), it is unable to open my modem. This happens both as a user and as root.
* system-config-network is unable to find my modem.
Everything is set as it is mentioned in the manuals. (suid /usr/sbin/pppd, etc)
I would like to be able to use gnome-ppp as non-root user to connect. Remember that it is not pppd's fault because wvdial connects (even as root), but gnome-ppp fails both as user and root....
