Gnome PPP Must Run as Root!
Posted: Mon Apr 04, 2011 8:50 pm
This is the output I got when trying to dial-out with the included Gnome PPP (GUI front-end to WvDial) in LMDE (201101):
(ttyACM0 is the location of my USR 5637 USB modem. See the recent posts in the thread Dial-Up GUI: In Which Editions?! for more info on analog dial-up modems and Linux)
I then proceeded to run GPPP as root by opening it from a terminal in which I had first invoked root privileges* and it worked! I was able to establish a successful PPP dial-up connection.
(*I used the su option:, then two separate commands, but the "Ubuntu way", using a single sudo command, also seems to work: )
(I got the idea from my experience with GPPP in antix 8.5; there GPPP would connect but then immediately afterward disconnect with the message,
Thanks to the kind folks at the antiX forums, I learned that the workaround is to run GPPP as root. In antix, I did this by using the "Run" box to open GPPP, checking "run as root". In LMDE, I did not find a "Run" box, so I decided to try using a terminal to run GPPP as root and the rest is history...
Note that KPPP in SimplyMEPIS has a different problem-- along with a different solution; see this post (esp. the very last part) at the MEPIS Community Forum.
I should point-out that I'm way out of my league with LMDE but when I learned it came with GPPP, I was so surprised that I decided to give it a try and see what happens and I actually fumbled my way through installing it just hours ago. This is my first boot-up after installation and, after the turbulence I encountered trying to update, I fear it may prove to be my last as well....
