timeout

timeout

[tony.chamberlain]

I am using pptp which calls pppd.  I use ip-up.local to add routes.

Problem is, when connecting, after only 10 or 15 seconds the link gets dropped
by the peer due to inactivity (I think it is the peer and not me).

Anyway I can make a stupid script to ping the other side every 5 seconds, which keeps the link up.  But there should be a better way.  I thought lcp-echo-request set to 5 would do it, but that sends only if it hasn't heard from the peer in 5 seconds, and by then it is too late.

Any suggestions?

Who is the peer? Are you sure you do not have a timeout where you thought
the time was in minutes but really is in seconds?

If you have added routes that change the route used by pptp for the GRE
packet stream, then the peer will drop the connection because the LCP
echo requests are not replied to.

Does the same problem occur without your route changes?

Which version of pppd?  Which version of pptp?

I'm surprised.

It would be more useful to see a "debug dump" log posted on a web page
for us to look at.
