Hey guys, love the podcast, as always...
The answer to the question is -sV Version scan probes open ports determining service & app names/versions

Additionally, I am glad Syngress is supporting a security podcast. I have spent quite a bit of money with that company, and I currently own and have enjoyed much of what they have published.

What does nmap v4 -sV option do?

It's the version scan option. Utilizes the nmap service fingerprints to discover the service a particular port is offering.

nmap -sV
Version scan probes open ports determining service & app names/versions

The answer to the question is -sV turns on "Versions Scan" which will try to gather the versions of software running on open ports.

Love the podcast been listening since episode 1.

Not that we in differnet time zones have much chance of posting first, but I'm a sucker for compos with books at stake ;-)

Nmap Q
-sV: Probe open ports to determine service/version info

Since I just listened to the podcast on my drive in, here is my submision. BTW, you misspelled Ed's last name in this post but got it right in the other post. Skoudis

-sV is not a new feature in version 4. It has been around since version 3.4. It hasn't changed in functionality, only quality, since it was first introduced. We have been using the feature and writing our own custom service fingerprints for quite some time. It was a great feature when first added because at the time, we were using amap to do version detection after finding open ports with nmap, but now, it could all be done with one tool. Fyodor and service version detection rock!
