Let's see I have a similar box (laptop - P233MMX with 192 mb of RAM) and it is currently performing the following duties on my home network:
- CUPS print server
- bittorrent client - for those long downloads when I don't want to leave my power-hungry desktop running.
Enhanced CTorrent is a nice command line bittorrent client. Plus I can start torrents from work (via SSH - see below) and they're done by the time I get home.
-
Privoxy proxy server. I route all my other comp's internet traffic through this one in order to get the benefit of Privoxy while only having to maintain and run one instance of Privoxy.
- SSH server for remote access to my home network
- End point for an SSH tunnel that I use for web browsing when I'm on potentially unsecure networks or networks I don't control (work, airports, hotels, coffee shops etc.) If you've already got the SSH server and Privoxy working properly, it doesn't require any further config on the server end. There is a nice writeup on how to do it
here. The author uses a Windows server, but it is even easier to set up the server on a Slack box.
- And finally, even though I don't use it very often, I also have a
Tor client installed. It has to be used in conjunction with Privoxy (or another similar proxy), but it works nicely.
The box has plenty of power to handle all that. Hell, I probably could do more with it, but right now that's all I need it to do.
Hope that's given you some ideas.
