There is a general How-to on using Linux Firewalling tools here :


(as well as lots of other places on the net).

If you don't need a service running, or port open, then close it :)

Welcome to WebmasterWorld, badm4n.

Port 135 is for the Microsoft Remote Procedure Call (RPC) service and port 445 is for SMB. Are you running an open Samba share? In both cases, because you are running Linux, your machine is not vulnerable to the worms which attack these ports, but your ISP may have detected that your machine is responding on the two ports in question. As already mentioned, you need to ask yourself whether you need these services running - if you need Samba for networking to local Windows machines on your network, then you should secure it.

My recommendation over IPTables is to get an external router with NAT translation and an integrated firewall. They are incredibly cheap these days, and they protect the whole network with one device.

Go to System => Yast2 => Security and Users => Firewall

Activate, select external interface, use default settings

I used to use slackware exclusively... This site helped me quite a lot. It comes as quite the shocker, I'm sure, but:

[slackware.com ]
[slackware.com ]

and for package management/updating use:

[swaret.org ]

I left the Linux world before swaret had come out, so I've never used it, but apparently it's a life-saver.

And, for an all-in-one Gnome setup:

[dropline.net ]
