Hi people; i hope someone can help me with this.
Well in fact i am asking more to learn than to my concern of haveing some few open ports;
the thing is that I've got a Red Hat 6.0 box, with a 2.2.16 kernel (really stable; this is the secound year that the PC stays non stop with no clashes at all); and have it programed to be a "router"; I've programed it with IPchains because IPtables had not been released yet; and have the IP masquerading service.
Well the question is this one:
which are the ports that need to be open so that i can run ip_masquerade service?
I've got the 53, 443, 515, 1080, 5190, and 8080 ports open and i am sure that not all of them need to be opened to have the IP_masquerading service working; for example the 515 (spooler port; which I supouse has nothing to do with masquerading doesn't need to be open).
The second question; is how do i close those ports; which services should i kill to close those ports; or should i touch the inet.d file?
Well i hope someone can help me with this...
thanks.
