port listener

[Warzovsky]

Hi!
I'm using RedHat 7.2 and I want to know if there is a port listener available with the standard distribution...
Thanks.

Hello

You can use the old netcat (nc).
The nc (or netcat) utility is used for just about anything under the sun
involving TCP or UDP. It can open TCP connections, send UDP packets,
listen on arbitrary TCP and UDP ports, do port scanning, and source rout??ing. Unlike telnet(1), nc scripts nicely, and separates error messages onto standard error instead of sending them to standard output, as tel??net(1) does with some.

For more info see the "man nc".
