How can I block internet ports that are hackable (ftp,telenet) ???
I'm using Slackware Linux 7.1

ipchains if you're using the 2.2.x kernel

iptables if you're using the 2.4.x. kernel


-----

for 2.2.x refer to http://linux-firewall-tools.com/linux/firewall

its great for setting up a quick firewall with ipchains.


As for iptables, there are also numerous programs/scripts which will setup a firewall script for you. The only one I know off hand is gShield, I think it's available at http://muse.linuxmafia.org

Also, refer to the how-to's on http://linuxdoc.org (for firewalling) and http://netfilter.samba.org
