ppp compression issues
 

Hello all,
I recently configured an EVDO usb modem on my linux box and had to disable ppp compression control protocol (ccp) to be able to browse the internet effectively. since then I have installed linux in another box and decided to try browsing without disabling ccp. The initial internet connection worked fine but the subsequent connections gave me the same problem where the connection starts fast then dies quickly. I then disabled ccp and every thing was fine.

Problem: With the initial connection the output of /var/log/messages was "device ttyACM0 is locked by pid 611". with this output repeating every few seconds I was able to browse with cpp loaded. On subsequent conections this output was not seen and no browsing was achieved.

Could someone shed some light on what this output means. Is there any setting that can fulfill this output so that I can reload ccp?

Thanks in advance.

Guessing here. (K)PPP has a config file in /etc/ppp/config and creates a log file in /var/log/ppp.log. There should be the path to the lock file somewhere therein. Go to the relevant directory and have a look whether the lock-files don't get erased after the termination of your connections. If so, delete them by hand and try again.

Sorry, cannot find file ppp.log in location indicated. Is there another path to the lock files in FC5

Is there any benefit in having ccp load??

In that case do a search of your system, I don't know where Fedora stows logs. You might as well start KPPP and search for the lock files as well. As to ccp I honestly don't know, never had that problem...
