I just made another attempt some six hours later, this time logging the
network traffic in ethereal. The log seems to indicate that the problem
was with the server, but I know nothing about the protocol.
In the packet description lines below only the lowest protocol level is
shown. So, packets carrying AOL data are shown without TCP details.
Licq sends a UIN request, the server sends a TCP ack counting the bytes
of the UIN request (so it has received it)
My PC sets up the TCP connection by sending the first SYN packet
7 TCP 54129 > 5190 [SYN] Seq=0 Ack=0 Win=5840 Len=0
8 TCP 5190 > 54129 [SYN, ACK] Seq=0 Ack=1 Win=16384 Len=0
9 TCP 54129 > 5190 [ACK] Seq=1 Ack=1 Win=5840 Len=0
The server is the first to transmit data over the connection:
10 AIM New Connection
My pc tcp-ack's the packet but sends its own New Connection:
11 TCP 54129 > 5190 [ACK] Seq=1 Ack=11 Win=5840 Len=0
12 AIM New Connection
Thew server tcp-ack's the last data from the pc, then my PC requests an
UIN:
13 TCP 5190 > 54129 [ACK] Seq=11 Ack=11 Win=16384 Len=0
14 AIM Signon AIM Signon, Request UIN
Again the server tcp-ack's the data from my PC, but then the server
sends a refusal. The details further down show a reason for the refusal.
15 TCP 5190 > 54129 [ACK] Seq=11 Ack=88 Win=16384 Len=0
16 AIM Close Connection
Here are the details of the UIN request. The hex dump at the end

This seems (to me, anyway :) to indicate the reason is with the server,
not with licq. What I find strange is that i could use gaim between
failed attempts to use licq. I did a dns lookup at the time of the first
failure, and got an ip address different from the one used here.
