Well, I’m a huge fan of SecureCRT. It is great when connecting to two gate keepers, two gateways, etc and keeping all it’s information tabbed and saved for quick access. However, this fine piece of software does come with, what I believe to be, a steep price. However, thanks to Ciscoblog.com I have an alternate solution. I just started playing with it, but so far it looks great.
