Hi David,

Been having a look at your “Cool IOS commands ebook”, great collection of tips, only wish I had found it before my CCIE lab!

Thanks for the great tips, i knew it was possible but could not recall the command for this and other tips  like sending messages via TTY etc... can be helpful when in a sensitive area no mobile etc... with voice / unified comms developing so fast more tips in this area would be very welcome.

Thanks again.

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.

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!

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 :)
