Thanks pppd! lcp-echo-* are always written in svn r4209, including when they are 0.

Re: Mobile Broadband - disconnect after 2 mins.
Thanks for the reply, Dan. I didn't see these replies until after I submitted comments on the bug report. In those comments I gave you the appropriate syslog entries showing that pppd logged four unsuccessful LCP echo requests and terminates the connection after 2.5 minutes. B! Your work towards overriding pppd's default options looks like it should do the trick.

If the box in the connection editor is unchecked, NM will _not_ send lcp-echo-interval or lcp-echo-failure to pppd. However, if those options were specified in /etc/ppp/options at all, it appears that pppd will read that file no matter what, and thus you'll get lcp echos turned on even if NM didn't tell pppd to turn them on. I will modify NetworkManager to always pass lcp-echo-interval and lcp-echo-failure as "0" whenever the box is unchecked in the connection editor, to ensure that /etc/ppp/options gets overridden, and that people don't get whiplash from stupid pppd config hierarchy... > Yes, well spotted!

It's probably the LCP echo thing. NM does print out the PPP command line being used in the logs, can you see if the lcp-echo-* stuff is on it? I do see the checkbox bug, but it's always unchecked for me, indicating that lcp-echo-interval is never sent to pppd. On latest SVN, even with the checkbox bug, ppp connections use: nodetach lock user blahblah ttyS1 noipdefault usepeerdns ipparam /org/freedesktop/NetworkManager/PPP/0 plugin /usr/lib/pppd/2.4.4/nm-pppd-plugin.so and thus no LCP echo. Could you reply with the PPP command line that NM executes pppd with so we can see what you've got?

Thanks, I'd forgotten about default ppp options, that tweak works for me too. So the problem is 2-fold: 1. The "PPP echo" option in the UI is not implemented, and stays off. 2. Nothing overrides the default PPP (LCP) echo options, so even though the UI says off, if the default is on, echos are still sent. Is it a common feature of broadband modems not to handle LCP echo properly? I guess it's not really needed anyway.

Re: Mobile Broadband - disconnect after 2 mins.
I just submitted this bug, which was noted as resolved... but I can confirm that the problem still exists. http://bugzilla.gnome.org/show_bug.cgi?id=556781 I had been testing NM from PPA for Ubuntu Hardy... and now I'm testing NM 0.7.0 included in Ubuntu Intrepid, and I still see the same behavior. The CDMA connection does not have the "Send ppp echo packets" checked... which was explained to me as LCP echo. In the bug report, I also noted a work around, which is to disable LCP echo requests and interval setting in the global PPP options file: /etc/ppp/options: lcp-echo-interval 0 lcp-echo-failure 0 This resolves the issue for me. Perhaps you can also comment on the bug report. -- Gilbert Mendoza PGP: 0x075DBCA9 Email: gmendoza at gmail.com http://www.savvyadmin.com https://launchpad.net/~gmendoza https://wiki.ubuntu.com/GilbertMendoza On Wed, Oct 22, 2008 at 10:18 AM, Rick Jones <[EMAIL PROTECTED]> wrote: > Having hacked a binary patch into NM (just for the init string) so my Palm > modem will connect, I now find that it systematically disconnects after > exactly 2 minutes. > > In the log, the modem state suddenly goes from 8 -> 7, and then everything > unwinds.
