I usually don't cross-post information about articles my other sites, but this one has some information that might be useful for network professionals.

I've just posted an article that shows how to use Nmap to get an accurate perspective of network response time. If you're just using a ping command to check for response time, you're missing an opportunity to gather more accurate network response time measurements. Have a look and let me know what you think!

Ok, not really. http://www.networkuptime.com/archives/2007/09/its_flattering.html I'd like to thank everyone for their "heads-up" email messages regarding an article that Slashdot.org featured recently. I tend to agree with most of you, there are shocking similarities to Kirby "Kev" Tucker's article and my Nmap ebook. Shocking, I say.

That said, the management of the site-in-question is already in touch with me, and they're handling things well thus far. Thanks again for your support!

Who says you can't mix work with pleasure? I've done both in my latest article, Under the Surface of Azeroth: A Network Baseline and Security Analysis of Blizzard's World of Warcraft.

Do you know someone at work who runs a few raids during lunch? Does this World of Warcraft activity on a public network pose a security risk for the end user? Should the usage of World of Warcraft across the network be a concern for an enterprise network administrator? Does the World of Warcraft game client pose a risk to enterprise security?

I've analyzed the operation of World of Warcraft, step by step. How does the World of Warcraft upgrade process work? How much bandwidth does World of Warcraft use? I've included trace files and utilization graphs for the complete story. Read it all here:

]]> Nmappers james_messer 2007-02-08T08:48:47-05:00 The Countown is Underway! http://www.networkuptime.com/archives/2007/01/the_countown_is.html One of my readers sent me an email last week and asked where I’d been, so I thought I’d post an update. I’ve not posted anything on Network Uptime lately because we’ve been extremely busy with a new Nmap-related project. Although it’s taken a long time to complete this project, I know that many of my Network Uptime readers will be interested in what we’ve created.

This new project was the result of feedback I received from the owners of my Nmap book, “Secrets of Network Cartography: A Comprehensive Guide to Nmap.” My book owners have provided some great feedback, and I’ve sorted through months of survey results and email messages to create an end result that’s been designed in part by the Nmap community.

So, here’s the big announcement. On February 21st, ProfessorMesser.com will release the Internet’s first Nmap training course, “Nmap Secrets.” Right now we’re busy behind the scenes, putting the finishing touches on “Nmap Secrets” and working on some additional suprises. You’re going to love what we’re doing next month!

If you’d like to learn more about “Nmap Secrets” and get on our insider list for some special free events, be sure to sign up to our mailing list today.

I have been assigned a project within my organization to perform OS Fingerprinting on subnets. What I find is that end-users that do not use Windows Firewall (have it disabled or not installed), I am able to detect their OS with no problem. The problem lies that many new users have Windows SP2 Firewall enabled which are limiting my scan results. I am using the following nmap command in Linux. (# nmap -sS -O -PI 192.168.0.1/24)

What should I do to accurately perform an OS Fingerprint scan on my subnet? If not 100% accurate, what nmap commands would your suggest?

It's the feel good hit of the moment!

I was traveling this week, and I found myself doing some late-night research in my hotel room for an upcoming nmap project. I wanted to do a quick scan, so I picked a device on my local subnet and performed a default nmap scan. I was expecting the results in a few seconds, but I was surprised when I didn't get a response back after ten seconds had passed.

In the new Enterprise Software category, I've added Business Process Management (BPM), Customer Relationship Management (CRM), and Storage Software sections.

If there are other sections you'd like to see, or you want your favorite program shared with others, let me know!

There's also an important group of nmap enthusiasts that have purchased my book, Secrets of Network Cartography: A Comprehensive Guide to nmap. To support their efforts, I've started a mailing list specifically for book owners.

Not only will this list keep book owners up-to-date with the latest nmap information, but I've also put together some exclusive bonus nmap information!

As a book owner, I won't add you to this list without your permission. I've already sent an email that must be confirmed to be added to the list, but I've already seen that some of those messages didn't get through some spam filters.
