Snippet

I recently had an issue where one of my Mac’s would not go to sleep whatever you tried.

It used to be something that couldn’t really be done on a Mac but I have just read through the documentation and it turns out that anything 10.

Whilst I have been studying for my CCIE I have been lucky enough to have access to a rack of equipment at my workplace which pretty much (apart from some different WIC’s etc) matches the INE topology.

Earlier today there was an issue raised on one of our new(ish) ME3400 switches that we have started to deploy to customer sites.

Earlier today Network World posted an article regarding a vulnerability that had been discovered in the OSPF (Open Shortest Path First) routing protocol.

After the last post when I had built up and installed my new Dynamips server along with a set of Sun Quad NIC cards (501-4366, HME or Happy Meal as they are also known) I started to run into some issues.

If you are having issues with your PIX/ASA firewall (or people believe that there is) there are a couple of checks that you can do just to make sure that the issue isn’t the firewall (as the server guys usually point at the firewall first!

Just as a quick note that over the next few months I will be posting a number of ‘snippet’ posts on various technologies and things that I have learned.

In the example below we have three BGP autonomous systems (AS1, AS2 and AS3) each with one router in it.
