This may be related to my question on security when using slack 14.1 as a production server. I do my development on a workstation running slack 14.1. There may be a couple hundred devices on the network, mostly windows boxes, plus a handful of printers and such. My config is the same as our Slack servers - custom configuration for php and apache, and everything else is default slack configs. Is there anything that can/should be done to make the box more secure, or more hidden from prying/probing eyes? I'm more concerned of people out there scanning/probing me, then on anything on the box getting out. I'd be very happy if the presence of the box was as hidden as much as possible.

I'd look for suggestions on the Security forum, but for starters, you could run the usual network intrusion tools to try to detect and break into your machine, from one of the servers. For example, for more hidden: try running nmap and make sure there aren't any services or ports showing that aren't necessary (probably not with default slack).

There are some very basic things to do to secure your PC, like editing /etc/hosts /etc/hosts.deny /etc/hosts.allow files; plus a few more *.conf files. Here is a link:

Also must see http://www.slackbook.org/

There are easy to follow instructions here. Hope its not too basic.

One thing I always do is disable listening on port 6000

Create the file /etc/X11/xinit/xserverrc (not present in default Slackware)
and put inside...Does not need to be executable, btw.
