If you log the traffic with pflogd, you can read the logfiles
with tcpdump -o which will lookup from /etc/pf.os to guess the
OS type.
Thanks. I got a good suggestion that look like might do the job. Will
know latter:
sudo tcpdump -o -lvvvnr /var/log/pflog 'tcp[13] &0x12 = 2'
I need first to increase the "snap len" for pflogd and then enter all
these IP's in a table and start logging.
Not sure if the results will be any use, but without doing it, I will
never know.
Last, as for the signature that may be different on the same computer if
control by a webbot, is that possible? I guess not as the TCP stack
isn't changed, but anyone know for sure? I am curious on that part.
