Exclamation Application delay when ppp is up

Hi !!

I installed a Mdk 10.0 distro with Kde on my Asus notebook (L5820).

Everything was running fine with the "default" kernel.

Then I compiled a 2.6.7 with "standard" options in PPP networking, using the same modem driver (SmartLink).

Now when I connect to the internet (Kppp) and I try to launch any application the system sits there doing nothing for 5 seconds (the icon blinks and jumps, but the hd is idle) and then gets to work.

When ppp is down everything works like a charm, with very impressive performances.

I looked for help in /log/messages, but there are no errors or warnings at all.

I think that this delay is a sort of NETWORK TIMEOUT, or something like this, resulting from some funny option I didn't set in the PPP kernel configuration.

Please help !!!

Thanks a lot, Nanni

Are you using KDE by any chance? If so, then it sounds like your connection to the dcopserver process (used to increase start-up times in KDE programs) is blocked somehow, or the process is being killed.

The first thing to do is to check if dcopserver is working when ppp is up, with the command
/sbin/pidof dcopserver
which should output one or more numbers if it's running.

Secondly, check your firewall configuration. Are you blocking on the lo (loopback) device? If so, check which ports are being blocked.

Hope that helps,
