No I did it manually. I know exactly, that I first ran tcpdump and then inititated a callout via ping ;-) Yesterday the yearly year++ counter increased, but I think I got the above task still managed properly ;-) > > Something special needed ??? > > Try to run tcpdump, and then establishing the connection.

Well all we want to see is what goes wrong in some cases, when the line goes up. Why the callout happened is of no interest, I don't see the logic (-n thingie) in this special case ;-) > Also ask your provider for hints from the dial-in server's log, why > authentication might be failing. Radius log shows, that I properly logged in... Might IP header compression cause a race condition ???
