[Succ: successful conversation; Fail: failed conversation]
The first point of departure is at packet 8:
Succ: HTTP/1.1 304 Not Modified
Fail: HTTP/1.1 200 OK (text/plain)
Both responses from debian.org
Then at packet 14:
Succ: GET /dists/squeeze/updates/Release HTTP/1.1
Fail: [TCP Previous segment lost] Continuation or non-HTTP traffic
(text/html)
The succ is a request from me; the fail is a debian.org response. The
corresponding line on the fail seems to be at packet 16. Packet 15 is a
dup ack in response to 14 (dup of 13).
The debian.org response to packet 16 is:
Fail: HTTP/1.1 304 Not Modified
The failed conversation then ends with a dup-ack, a fin-ack, a dup-ack,
a fin-ack, and a ack, in alternating directions exc. for 2nd fin-ack.
