/* more to it. Cycle through a range of ports - and see what */
/* happends. It doesn't appear to matter if the port is */
/* opened or closed :-) Since NT won't let this happen again */
/* on the same port, you simply change ports, and you can */

/* If using, VI, tab=3 (press ':', then set ts=3) */

Subject: new TCP/IP bug in win95
hi,
i recently discovered a bug which freezes win95 boxes. here's how
it works: send a spoofed packet with the SYN flag set from a host, on an open
port (such as 113 or 139), setting as source the SAME host and port
(ie: 10.0.0.1:139 to 10.0.0.1:139). this will cause the win95 machine to lock
up.
the piece of code included in this message does that, so... have fun!
i haven't tested this bug on other platforms, i don't have the
ressources. please feel free to do so.
