Ive recently been playing around with netcat and setting it up as a server and noticed that if u have some sort of authentication(so u need to enter a password) but enter no password and quit (through the CTRL+C control)then netcat goes into an infinite loop and you cannot connect again :|

It also happens if u dont have any authentication - ie u connect, press CTRL+C and then enter.

Any1 else have same problem or is it me being an idiot

have you try cryptcat
WEBSITE

Yup cryptcat is based on netcat and has the same flaw

i think he is not listining any more (not active)u have to active in 1more time
