Red Hat Bugzilla – Bug 388701
RFE: integrated PPP support
Last modified: 2009-01-09 02:26:52 EST
Description of problem:
ppp connections are no longer shown in nm-applet - regression
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. open up nm-applet and dialup/ppp connections are not shown
no ppp connections in drop down menu
ppp connections were listed in dropdown, worked fine in F7
yum upgrade from f7 to f8
Is there any information I can provide to progress on solving this regression?
it looks like this is the same bug i reported at 380771 2 weeks ago
still no answers there either...
and of course no alternatives to network manager
The PPP support in NM never worked well (didn't allow VPN overlays because it
was really just calling "ifup <connection>" underneath); it's been ripped out
and replaced with a more robust mechanism which will be coming along soon. It's
already in uptsream SVN and works with 3G connections. What specific type of
PPP are you using? 3G card? serial modem? ISDN? PPPoE?
It is a 3G card.
Specifically a Sprint EX720 which Linux sees as /dev/ttyUSB0 (thinks it is a GSM
3G card here as well that Linux sees as /dev/ttyACM0.
Mobile broadband cards are the current target of the upstream PPP work that
landed last week. It's currently GSM-based cards only, but since I have access
to CDMA cards only (and they are less complicated than GSM-based cards) it won't
be hard to add support for CDMA cards too.
@dan: which specific card do you have? Sierra? Novatel? What bus does it use,
PCMCIA, CardBus, etc? I don't immediately recognize what bus creates devices
with the ACM prefix...
It's a Verizon Wireless PC5750, which appears to be manufactured by Audiovox
based on this link: http://www.evdoinfo.com/content/view/863/40/
EV-DO Rev. A. It's extremely simple; With Verizon cards I have always just
addressed the device (be it ttyUSB0 or ttyACM0) as a modem and for Verizon
dialed #777. No special init string is required like for the GSM cards.
Let me know if you need more info.
That looks good, I have a Sierra Wireless Aircard 860 which is also PCMCIA which
I'm using for testing, so PCMCIA support should work fine when we're all said
I'm going to use this bug as a tracker for the well-integrated PPP support
that's coming soon. There will be another bug for Mobile Broadband card support
specifically (bug 296851). Please put all 3G type stuff in that bug, and we'll
keep this one as a general PPP tracker (on which the 3G support obviously depends).

Dan W., I have a Sierra Wireless Aircard 875 through Cingular/At&T. Using F8 on
a Thinkpad T60. Let me know if I can be of any assistance testing or whatever.
Should have todays update for F8
0.7.0-0.6.6.svn3109 done anything for this issue?
@kevin: no, the upstream PPP stuff dropped after 3109 was rolled.
I can confirm no change of behavior with regard to PPP in the 3109 version;
other issues with this version documented under other tickets (411411) as well.
Note that while I will work on PPP bugs in _Fedora_ NM as I have time and when
more important things aren't breathing down my neck, the PPP functionality is
present in the latest builds. You can try it out by doing the right thing with
a .fdi file to attach the modem capability to your card.
Can you explain what these .fdi files are and where they go. I got the latest
version of NM from Koji and I still don't see NM picking up my 3G card and I
don't see any .fdi files in the package so I don't have anything to see as an
Same problem here. NM in FC7 automatically offered ppp connections created
using system-config-network but the FC8 version lacks ppp support
I'm using latest rawhide and NetworkManager doesn't recognise my PPPoE
connection made by system-config-network with enabled NM control .
It's not in the DSL tab in NM "Edit Connections...".
@nikolay: NM does not recognize PPPoE system connections yet.
@miroslav: is this for normal modems, 3G cards, Bluetooth DUN, or PPPoE?
for any generic (/dev/modem) modems
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
