NM must override all essential ppp options from /etc/ppp/options (Was: System lockup with Network Manager with CDMA Verizon V620)

[Michael W.]

Binary package hint: network-manager

NetMannager has no problem identifying or connecting with the network using a Verizon Aircard V620, but the system freezes after about 2 minutes of use. A hard reboot is required.

I tested my configuration using Gnome-PPP and the card is recognized and runs without a problem.
When the freeze takes place and there is no dump of log entry produced.

Thanks!

I am using Ubuntu 8.10
NetworkManager 0.7~~svn20081018t105859-0ubuntu1

I had this same problem with my KPC680 card. I am using a slightly newer version of NetworkManager with 8.10. I was able to resolve the problem by modifying the /etc/ppp/options file. The following lines should be changed to 0:

lcp-echo-interval 0
lcp-echo-failure 0

That stopped my machine from locking up when signal was weak or non-existent. I hope this helps you.

please test the test package available here: http://launchpad.net/~network-manager/+archive

(just upgrade to latest). AFAICT that should properly set the ppp options. Please check carefully. I would like to put this fix in a stable update.

No joy. I upgraded to the latest test package, and I'm still getting to 2 minute in freeze. The text of my ppp/peers/wvdial options file follows with hope that it may bring some insight. This works fine with gnome-ppp. Pardon my lack of knowledge, but where can I check to see if the options file in use by network-manager is being correctly updated?

/etc/ppp/peers/wvdial:
noauth
name wvdial
usepeerdns
defaultroute
debug
crtscts
lock
noproxyarp
novj
novjccomp
lcp-echo-interval 0
lcp-echo-failure 0

thanks again,

Michael

I did add the lines:

lcp-echo-interval 0
lcp-echo-failure 0

to my /etc/ppp/options file, and it looks like I'm up and running. (Thank you Andrew!)

If the patch will fix this, I can test it out. Please keep me in the loop.

Thanks,

Michael

yes, we have to add a patch for those ppp options for intrepid update. we already have a similar patch in the -pptp package in network-manager PPA.
