I have been having a difficult time with gnome-ppp ever since I went from Dreamlinux 3.5 to Debian 6.0.3. At first it was not a problem because I had dsl and dialup was just a backup, but now that I have moved AT&T has not been able to successfully set up my uverse (still working on it though), so I am now dependent on dialup, and it is super slow if I access gnome-ppp through sudo instead of the correct way.
I figured out that the reason I could not access the modem was because I did not have permission. So I used
chown myusername /dev/ttyACM0
to change ownership to me. That works fine... until the following day; when I log into my computer, I no longer own the modem and have to change ownership all over again. This has been going on for nearly a week now. What can I do to make my ownership of the modem permanent?
