Nice video.
The -v option is verbose not for version but it did work to show the version.
However if you want nmap to show the version then exit, use the -V or --version option .
Does his shirt say "AD &HD"?! That's funny. I like it
simple and amazing tutorial
Hi Jay, Great video on nmap, very clear and informative, 1st class.
It would be so helpful if you could do a similar type of video, of you showing how to Secure Apache2, installed on Linode from malicious attacks.
Great video! This is truly an awesome tool
awesome as always Jay
Thx for another great video. I've been using Linux at a very low level for many years, but your vids challenge me to up my game!
Btw, what model speakers are those on your desk?
Great video!
Great work! Thank you
Glad you liked it!
A useful command to show would be nmap --script vuln public_ip where it shows as the option unveils, possible vulnerabilities
The circuit board wipe animation is nice.
Running even a ping sweep can raise an alarm in a business environment. I second the "get permission" advice even if you don't think you will need it. I once scared the crap out of the ops team manager by scanning for a lost machine from an unexpected place on the network. I apparently tripped an alarm that hadn't been there before.
a real world test, it worked, everyone should be happy ;-)
was looking for this !! New bee of Linux (rhel)
i am a poor man so i can not help you , but i can thank you for the great content you made for all the ppl no matter of !!! peace !!!
Thank you.
Intro should be the outro, imo
Other fun tools are ipcalc or sipcalc for learn about netmask etc.
Thanks!
Very lucid explanation. nmap is underrated.
For the hackers here, can you show how to do an idle-scan?
Can you scan some public machines (internet), that are vulnerable?

What video editor you are using? Thanks
Hello Jay , can you come up with a series on linux troubleshooting , where you break something in linux and then try to fix it . You can team up with some linux TH-cam content creator on this. This wil be great
I literally can’t live without nmap
Hey ,please make deployment series in depth
Anybody know how to learn deployment
nmap ipv6 demo would be nice, example babe::20 is an acceptable address.
could be used to manage wifi access points thru their ethernet ports, wifi clients only get ipv4.
nmap(1) support IPv6 too, basically in the same way.
👍👍
Nifty
👍
it won't play on firefox somehow, chromium plays it fine, other videos play on firefox too, but not this one
"Hey Jay how many women are you currently seeing?"
Jay: 6:45

As always your videos are great
every redirect link in every video of yours is broken
too much videos since too many years on nmap nothing new tho
Oh man, that shirt is cringe.
