I am still experiencing problems with Linux Networking. Telnet sessions from the
same host are
stalling others are still moving along. Can anyone shed any light on why
there is a huge send-queue for one telnet session and not for the other?
Setup: Dialin from Linux System at home (2.0.8) into Modem Server (2.0.8).
Telnet session is from the home system to another host on the network which
runs a full Usenet feed. Two systems are running Debian 1.1 one Slackware 3.0.
In both of these cases the stalling session was running tin to read news.
I have removed diald for these tests. Just ppp-2.2.0f is involved.
