Hi All!

I've got an interesting problem. My pppd started with demand option and 
sometimes it brings up phone line with no network activity. I'm tried to 
recognize this but I can't do it with tcpdump - open connection longs too 
small amount of time. My modem keeps connection alive for 3 minutes (idle 
180) and this is not good. I suppose this happens because of DNS updates. I'm 
trying to start pppd with option:

active-filter 'not (src port 53)'

to disable dns demand dialing, but starting pppd causing error message:

pppd[2073]: Couldn't set active-filter in kernel: Inappropriate ioctl for 
device 

What does it mean? How can i set pppd active-filter?

Thanks!
