Hello guys,
I don't know if I choosed a right section for this topic.if not please one of admins move it to a right place.

anyway I've found something intersting.
I've installed metasploit framework 2.3 on a remote box and I connect via telnet. it worked nice (not colored offcourse). then I started a netcat to listen and bind a shell to it and log off telnet. (start nc -d -L -p 8080 - e cmd)
then connect to that port (nc -vv IP 8080) and run metasploit. but it had problem.
I didn't got the prompt of Msf. just see the banner. it seems that commands does not parse to Msf console and echo's does not come back.

what is wrong here ?
