Subject: Mac TCP/IP Stack glitch.
Hello,
Recently I found an interesting problem with the macintosh tcp/ip
stack with system 7.1 and 7.8. It seems that if your send a large
quantity of tcp syn's at a high rate Mac tcp 7.1 crashes and 7.8 uses ALOT
of cpu. To recreate this bug just get a copy of strobe and portscan a mac
until it hits all 65535 ports, they will see the effects. If this is
already a known problem let me know, or disregard this message, but i
haven't seen anything on it yet.
Even more stack problems from,
