CRON

I wasn't able to sleep last night, trying to make my script work. Actually, it works manually but if ran through cron it doesn't work. It was a very painful, and yawning, debugging. My only clue is, that cron can only run commands with complete path. But to simplify my job I was using other existing tools and utilities. And debugging means going inside every one of them, making sure every command was called using their complete path. In the end, I decided to give up the tools/utilities and write them myself.

Finally, IP forwarding works.

It's hard to find a good tutorial for IP forwarding even using my favorite search-engine google. No tutorial to discuss the intricacies of IP forwarding, just do this or do that. I think I found one good site, http://www.faqs.org/docs/iptables/, authored by Oskar Andreasson. It's a good read. I also found a more application-type tutorial but I forgot the site. Anyway, to give credit to the site owner, I'll try to llok it up and post it here later. Again.
Up next for me is Double NATing.

IP Forwarding

Having a hard time making my IP forwrding work. The problem actually lies in determining to what extent we should expect IP forwarding to work. Is it stand-alone or do we need to set routing.
We need to discuss about this tomorrow.
I am very thankful to the online IP forwarding tutorial which I will gladly post here on my next blog.
