i4b - FreeBSD 3.1-STABLE (Feb/March) communicating problems

Guckux Hellmuth

So, heute Abend mal einiges rumgespielt...
Configuration:
Teles 16.2

Configuration mit:
isp versucht zu connecten zu einer remote-Site mit dyn-IP: "keine
Kommunikation" möglich, wenige Bytes tröpfeln über die Leitung.
isp versucht mit ner CISCO AS5200 zu connecten, gleiches Ergebniss.

interessant sind die tcpdump Ausgaben beim listening. Ich glaube ich
brauche Dir dazu nichts weiter zu erläutern.

Bei ersterer Connection kann ich Dir jetzt nicht sagen, was auf der remote-
Site steht, bei zweiterer ebend ein CISCO, bei beiden kamen auf pings
keinerlei Antwort seitens ping, tcpdump spuckte aber aus, daß Pakete
zurückgekommen wären...
Bei telnet zB klappte ab und an es, den login zu sehen, den Usernamen zu
sehen, aber ein paar Zeichen später war dann der Ofen aus.
Die Verbindung existierte weiter, blieb aufrecht, es wurden weiterhin
fleissig Pakete rausgeschickt (ping >>isdnd-monitoring) und es kamen auch
rein (siehe auch tcpdump).

Bye
