Using nmap to scan networks (Awesome Linux Tools)

nmap is a network mapping utility that you can use to gather information regarding the nodes on your network. With nmap, you can perform port scanning, OS fingerprinting, and more! In this tutorial, you'll learn the basics of using nmap.

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 .

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 !!!

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.

Does his shirt say "AD &HD"?! That's funny. I like it

[Handelsbilanzdefizit]

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?

[dimitristsoutsouras]

A useful command to show would be nmap --script vuln public_ip where it shows as the option unveils, possible vulnerabilities

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 YouTube content creator on this. This wil be great

[anoldslowhorse]

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.

[AndersJackson]

Other fun tools are ipcalc or sipcalc for learn about netmask etc.

[seanunderscorepry]

Great video! This is truly an awesome tool

[PhrozenN]

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?

[behindthescene]

was looking for this !! New bee of Linux (rhel)

[jyvben]

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.

[joseloeza]

What video editor you are using? Thanks

[_priyankrai]

Hey, please make deployment series in depth
Anybody know how to learn deployment

[madkvideo]

"Hey Jay how many women are you currently seeing?"

where I can buy this shirt? what to buy it I also have ADHD
As always your videos are great

[samwork]

it won't play on firefox somehow, chromium plays it fine, other videos play on firefox too, but not this one

[theonewhowas]

every redirect link in every video of yours is broken

[Jango]

too much videos since too many years on nmap nothing new tho
