Vielleicht liegt das Problem wirklich auf meiner Seite, aber die runden
Zeitspannen die eine Verbindung aufrechtgehalten werden konnte sind
dennoch auffallend. Vielleicht habe ich mir wirklich einen der seltenen
linux-Viren eingefangen (ich kann mir nicht vorstellen wo), aber ich
weiss nicht wo ich nachschauen muss -- ps ax ergibt nichts ungewohntes.
hier mal ein Ausschnitt der logs der letzten Woche (|grep 'pppd'):

am Samstag (alle Zeitangaben sind auf korrekte Zeit in Wien korrigiert worden).
Da also die Verbindung recht lange stabil war nachdem 1 Minute ohne Hangup
verstrichen ist, scheint es doch etwas mit der Verbindung und weniger mit
der Software zu tun zu haben. Als meine Telefonleitung noch nicht 56k erlaubte
hatte ich keine solchen Probleme, leider weiss ich noch nicht wie ich mein
Modem auf niedrigere Geschwindigkeiten umstellen kann -- denn auffallend
sind die vielen Kompressions-Fehler die bei einer Verbindung auftreten...
