Calculating TCP/IP MTU for VPN traffic

Situation: Calculate optimum MTU for TCP/IP traffic in a VPN. It took me quite awhile to track all this down.

Resolution: The best solution is to have the router adjust the TCP for the Maximum Send Size. Continue reading ‘Calculating TCP/IP MTU for VPN traffic’

Setup Favicon on Website

I know this is covered all over the internet already, but I keep forgetting myself…

Situation: Want to add a Favicon to website (that little icon next to the URL in the address bar of Browsers like FireFox, and in bookmarks of sites in IE6). Continue reading ‘Setup Favicon on Website’

Setup SSL Certificate on Cisco 3000 Series VPN Concentrator

Situation: In this case we went with a SSL Certificate from GoDaddy.com because of price, and the hot chick in their advertisements. The problem arose from the fact that the CSR (Certificate Signing Request) wasn’t generated from the Cisco VPN Concentrator itself.

Apache mod_radius_auth to Active Directory

Situation: Setup Apache on Linux to authenticate to an Active Directory Domain based upon some unique identifier of the site (the server hosts multiple sites).

New Section & Updates

There’s a new section of the site, I’ve affectionately called Technical Tidbits. It is a space, where I can ‘give back’ to the Internet. A spot to write-up all those things (problems, jobs, and projects) that I either have to come up with a solution to myself, or have an exceptionally hard time finding answers to online. This is something I’ve wanted to do for quite awhile now, but have finally gotten around to doing.

I start off the series with something I don’t think exists anywhere else online:
How to set and use Custom resolutions in Warcraft III on a Mac.

All the posts will be tagged with the ‘technical tidbits’ category, and can be browsed via the ‘Technical Tidbits’ page tab.
