I am running Debian / KDE 3.3 / and 2.6.8 Kernel
I was wondering if someone could give me some help. I recently used the Shields Up service on www.grc.com and it detected several of my ports as open. I was wondering if anyone could tell me how to close or at least stealth them. The list of open ones i got is:
Port 9 - Discard
Port 13 - Daytime (RFC 867)
Port 22 - SSH Remote Login Protocol
Port 37 - Time
Port 111 - Sun Remote Procedure Call
Port 113 - auth/ident
I have heard that stealthing 113 can cause some problems with IRC and FTP. And i think i will be able to close 22 by shutting down sshd (unless i need it for something, but i don't think i do). I have iptables installed, but don't know how to configure it.
Any help would be greatly appreciated. Thank you.
