Netcat question / Port redirection?

[sana2005]

hello guys

i am running ncat (netcat's new version from nmap) on centos . I am listening on different ports. My question is , is it possible that when a connection is received on a port say 123, i redirect this connection to a different port and use the 123 port again for listening connections.

ncat has an option -k which u can add with -l , it will force fully listen on the port. It can accept multiple connections on a single port but i want that once a client connects on to 123 port, he is forwarded to some other port and no longer on 123 .

can any one give a solution to this problem?

how doesn't it? once someone connects, you pipe that connection to another port.

because the port 123 will still be occupied.
