Mandrake 9.1, kernel 2.5.74. Started kmail, started kppp, connected, attempted
to send or receive - nothing happened. Run netstat -an - and got

this happened more than once; previous stack (I do not know actually what
triggered it - I did not run netstat for sure) looked like:

Just tried and when connection is done while kmail is not started it works. I

forget it - with or without kmail, with or without connection established
