Sorted. Nice One. I'm still using 110 seconds as i keep on getting this line every 2 minutes 17:29:56.721278 cvx1a.bre.ntl.com > ALL-SYSTEMS.MCAST.NET: igmp query [ttl 1] As i'm not using NetBSD, my machine screams when i use the 'active-filter' option on pppd. Now what am i to do. Leaving it on 110 means that i have to keep on dialing up e.g. when i'm reading an article that takes more than 2 minutes to read. However, if i increase it, my link will never go down when a 'cronned' process brings it up. e.g. batch FTP at 2 am. Ohhh Woe is me that i have to suffer so. Woe! Woe!! :-) Any ideas?

I noticed that using multiples of 30 seconds allows the link to go down. Try 120 seconds rather than 110 seconds. Don't ask me why but it worked for me.

No matter what i've tried my ppp link refuses to obey it's timeout time. I've been using the 'tcpdump -i ppp0' command to monitor the interface for any packets that may be keeping the line up but to no avail. The command line that's used for setting up the PPP link - via wvdial.dod start - is

I believe what keeps up the line is the multicast igmp query - shown below - which i get every 2 minutes. If the timeout is left at 120 is doesnt go down. But when set to 110, it does. My reasoning is that the multicast query from ntl is what keeps it up. Iv'e tried using the 'active-filter' option of pppd but this can only be used by NET-BSD based systems. Anytime i use it pppd screams about the option. I'll just have to see how i can work around the packet query i receive. Reject it at the firewall perhaps. Hmmmmmmm....

Very strange. You could try 300 seconds, which was what I had before and it work quite well. I think there something else going on with your system. My "ultimate" solution was getting a DSL line and using PPPoe with a 24/7 connection. ;)
