>Description:
ipfw pipe for localhost causes machine to hang.
>How-To-Repeat:
I executed the following ipfw commands
ipfw add prob 1 pipe 1 tcp from 127.0.0.1 to any in
ipfw pipe 1 config bw 100MByte/s
Then I "telnet localhost 25" which causes the machine to hang. Not even CTRL-ALT-DELETE works. I have to do a hard reset to reboot the machine. All network connections to the machine is also lost.
