How safe is it (as a normal user) to open a specific tcp port to the world for gtk-gnutella to use?
If this is a major hazard then is there any other way to let it see the world?
I am using arno's (
http://freshmeat.net/projects/iptabl.../?topic_id=151 ) firewall at the mo and have changed a line in "/etc/iptables-firewall.conf" thus:
#################################################################################################### #############
# Put in the following variables which ports you want to leave open to the whole world #
#################################################################################################### #############
OPEN_TCP="xxxx" # TCP port(s) the whole world is allowed to connect to
OPEN_UDP="" # UDP port(s) the whole world is allowed to connect to
OPEN_IP="" # IP protocol(s) (non TCP/UDP) the whole world is allowed to connect to
OPEN_ICMP=0 # Enable ICMP reply for the whole world (not recommended)
ie. OPEN_TCP="port number"
seems to work but is it the best way of doing things?!
edit: the truth is, I have read up on iptables but still don't fully understand how to control it!
