port question
 

i am installing red hat and by default opens this port...
631/tcp open ipp does anyone can said to me how i can close this port?

To close this port you could either stop the process which has opened the port, or you could firewall the port. I think stopping the process is probably the idea, as you probably do not need the Internet Printing Protocol. So, I would look to either kill or remove that process. Voila, fixed.

Hope that helps, p.s. 'ps ax' and 'kill' would be useful in this situation.

J.J.E.

i can't find any proccess with ipp name

This port is connected to the CUPS printer system. When you point your webbrowser to http://localhost:631, you will see the CUPS setup pages. Disabling CUPS should close the port ... and disable printing (if you were using it).

:-)

Oops, in my system it is connected to CUPS, but perhaps you've got another printing system listening to the same port...
