I am a CCIE R&S & read your newsletter for quite some time now.

I think it is a very nice way of knowing sometimes not so difficult but hidden utilities in the Cisco IOS.

Keep it up !!

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!

I think the new version of the command memorizer is brilliant and has been a massive help during studying for the exams

Thanks for the quick response. Feel free to use the comments. If you’d like to add something else I will tell you that I found your proof-readers to be particularly good.

This is my 8th certification test in the last year and frequently the answers that are given are just blantantly wrong.

It was a good feeling to not find myself confused.

Hi David,

Your apps are some of the best I’ve seen.

I’m contemplating getting a my CCIE in routing and will be looking at purchasing your memorization tool. Thanks.

Hi David,

Just to let you know, I passed the IPTD exam last Friday.

Many thanks for a most enjoyable and productive course, I appreciate you went off track to cover the items I asked for (CCM 5.x and 6.0..etc) it was really appreciated.

Cheers,

Hi David,

I've only just scratched the surface with the CCENT Sims and they are just superb.

The Sims are exactly what I needed to pass and are therefore a godsend.

Many thanks to yourself for putting something so brilliant together.

I think the news letter is great! - Fantastic and useful information.

Not the normal junk I get in my inbox.

Great work !!

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 :)
