Cisco service configuration boot error

Are you getting one of these errors on a Cisco Device?

%Error opening tftp://255.255.255.255/network-confg (Socket error)
%Error opening tftp://255.255.255.255/cisconet.cfg (Socket error)
%Error opening tftp://255.255.255.255/3620-confg (Socket error)
%Error opening tftp://255.255.255.255/3620.cfg (Socket error)

Well, here is how you fix it.

Router#config terminal

Router(config)#no service config

Router(config)#exit

Router#copy running-config startup-config

And you are done! You will not see that error again!

Cisco - Regular Expressions

I have used regular expressions for years when configuring Cisco routers. However, the bulk of my use of them has been when configuring BGP. However now that I am using them for dial-peers in our Cisco routers used for our VOIP system, I have decided that I need to commit this information to memory. Up until now every time I write an regular expression I have to refer to the documentation.

For those of you in the same position as I am I have included some links.

Firefox Add-on - Ad Blocker

I have been using the Ad Blocker add-on for Firefox for a few days now and I must say it is one of the more useful ones I use. It allows you to subscribe to a list of sites to be filtered. You can customize that list as you see fit. However, my favorite feature of this add-on is the ability to simply right-click on an "image ad" and block it. This is really handy for me since most of the sites that host their own ads that aren't listed in the filter list provided with the add-on.
