David,

Just a short note to say that I passed my CCNA qualification yesterday.

This would not have been possible without your excellent classroom instruction on the ICND course and the Knowledge Verifier application.

My next goal is CCDA qualification and I will shortly be purchasing your Knowledge Verifier for the CCDA.

I would not hesitate to recommend your services to anyone who is serious about gaining Cisco accreditation.

Thank you once again.

This is my first newsletter, I came across your IOS tips ebook searching through google, and didn't mind getting the newsletter. Now, I'd like to say wow!

Its awesome, I'm really glad I signed up--kron jobs on IOS? I didn't know you could do that! The information is incredibly well presented.

When I can tear myself away from study, I'll update my blog, and give your site a plug, you provide some fantastic resources that you don't really see anywhere else, thanks!

Greets!

Thanks for the answer, it's been getting to me for months, and I just keep forgetting to ask you for a solution. You have no idea how much time that little command is going to safe me. I'm working on a huge security network which has over 80 firewalls some of which have over 3000 lines of access-lists.

It's a pain in the neck trying to find a single host with a certain port to see if the access-list exists, so this is going to safe me a stack of time :)
