Package: ppp Version: 2.4.4rel-10.1 Severity: important With a UMTS connection to o2 Germany, connections sometimes dropped. Looking into that issue with wireshark, I found out that the connection drops because a TCP package of length 187 + k * 240 bytes (with k in 0,1,...) never makes it to the TCP stack of the receiver (i.e. the computer where PPP is running). This can be reproduced using netcat and a 187 byte file. Analyzing the ppp recording itself using wireshark there are three ppp frames displayed for that TCP packet: one frame of length 240, one frame of length 241 and one frame of length 1. I wasn't able to reproduce this bug using Windows, however I only tried it with a 187 byte packet, I did not run extensive tests with variable packet sizes yet.
