ppp and sharutils are installed. 9menu and xosd are not in the repos and do not appear to be necessary. When I run the script, it asks for a root password, then doesn't recognize the modem, but allows me to choose it, then errors that it can't find the device.
I have an option 3g using AT&T's wireless (formerly Cingular). The apn is isp.cingular, the login is firstname.lastname@example.org
, password is cingular1. (The password is the same for everyone and there is no PIN).
It used to work with kppp until kernel upgrades about 3-4 months ago. (Still does, if I use the 2009.2 Livecd and build the module, etc.)
