port used by a chatserver -> how to make it stealth?
hello,
I'm running on my rh 7.2. box a chat server which opens a port. There is no security related problem with that, but for other reasons (prevent to access chat with certain programs) I'd like to have this port running in stealth mode.
Is something like this possible (mostly because its the port used by a chat)?
f.eg. If I do a portscan I see that this port connects... is there a way to block this but without having problems with the chat itself?
thanks a lot,
chris

If the program is active, it has to listen to a port, even if you change the port, it will have to listen to some port, or it won't be able to respond to incoming queries.

Hello!
hemm thanks a lot! This confirms that I really have to buy a good TCP/IP book for dummies asap :-D
could I ask you something related? F.eg. I've zonelabs running on my wincoz pc... and there are some sites around trying to portscan the pc you are connecting from ... just to see if your machine is exposed to some exploit.
Well usually this sites say that my wincoz pc is running in stealth mode on all the ports... even if I'm running icq or I'm inside some chatroom.
Isn't it therefore possible to run a chat server in stealth mode?
Sorry for reasking the same stuff, trying to understand and learn :-D
cheers!
Chris
