Ya can't just go around tell the normies about elite hacker tools like ssh. This is gonna get you another strike. Don't you know the first rule about ssh is shh.
legendary commentary
It's a scp
Elite hacker tool wtf, i like this comment because it sits on the line of it being either 8 layers of irony or being made by a 6yo thanks for this masterpiece lmao
"Elite hacker tool" boy what

I didn’t know how SSH works. Now I do. Thanks Mr Outlaw.
I didn’t even know it existed. Thank you Mr. Outlaw.
Yes, now for the other mystery in the life..does anyone know what a woman is?
@@Contractor48 they're a myth
@@Contractor48 is that some sort of forbidden torrent technique?
@@AshleyRiot I don’t know, I am not a biologist.
It would be great if you could do more of these informative style videos. I suppose the majority of your viewers are probably technically proficient so perhaps it wouldn't be worth it but I think you have an excellent way of explaining a topic without being condescending. It's nice to watch someone explain something without stopping for every tiny detail, but covering the concept in a way that people can understand and develop as a platform for their learning. Either way, great video Outlaw.
I agree! His style of presentation is informative and enjoyable. Perhaps a second channel would be good?
I'm still new to computer science topics and am trying to get out of the 'I don't know what I don't know' phase by absorbing as much as I can, so this video was great.
I also like this
I started watching this channel because of the technically informative videos. Now I watch this channel for multiple kinds of informative videos. I just hope Mr. Outlaw keeps churning out videos for us to learn stuff
I work in the industry and don’t know a lot of this as it’s not immediately related to my role, so, totally agree!
SSH is one of those concepts I've struggled with a bit in my IT studies. This video explained it perfectly for me. Thanks Mental Outlaw.
ssh is a life safer. My use cases
- Managing my servers.
- ssh config file is super helpful. Instead of remembering multiple ip's and ports, I can assign it a simple name.
- Public-private key authentication is super easy. More secure and much convenient, instead of typing password each time you ssh.
- Port forwarding with ssh to use a vnc viewer on my local desktop. Even tho servers are not meant to have a desktop environment, sometimes it is required (I use them with docker or lxd containers)
- Port forwarding with ssh to test/configure the website before making it public.
- Using sshfs, to mount a server directory on local machine. Kinda works like network storage.
I already knew a bit abt ssh so this video was more of a fun time killer. Super cool to hear examples of its versatility because when learning new topics I have a hard time grasping just how many places you can apply them.
ssh tunneling is fucking brilliant
@@TurkeyOW same. Learning the application of a topic is a bit tough when you're starting out. It's the fun-est bit tho... applicability is key 🔑👌
Another use: logging into a local vm in your regular terminal
another fun thing: proxy jump through a bastion host
In late 1990's, network was simple. PC's were connected to 'HUB', and it was very easy to 'sniff' connections. With Slackware Linux, I used program called 'sniffit' and I able to 'see' every connections in the network. IRC was very popular, and I able to 'see' all the chats and sometime I pranked them. :)
SSH not just replaced the rsh or rlogin, but also ftp and rcp too.
Thank you.
Aside from the bloat free, direct, and well articulated information you present every time... That creepy Joe meme at 2:38 is why you’re my favorite person on CZcams
And it's a lot more cursed if you know the character in that meme
Creepy Joe sniffing that poor unencrypted packet 😥
😅
Maybe a better idea of what padding would represent in your analogy would not to mix in decoy packages, but to use the same package size for each item you receive, so you could not theoretically infer information about the object inside by its size
This.
How does it do that? I was thinking it’d be more like putting rocks in the packages. But is this standard weight large enough so that no packet will need to be greater than it?
I am needing to use this with my Raspberry pi for a class project, having one of my favorite youtubers in this field explain how it works makes it even better
You've probably used ssh-keygen to create a private and public key file, right? I also assume you need to input your password when you log into your pi?
Use ssh-copy-id to copy your public key to the pi. You'll probably have to change your local config, but it's sooo nice not to type your password every time! :D
@@NostraDavid2 thanks for the tip, I’ll definitely be sure to try that
Thanks to SSH, SFTP exists. It's the same as FTP but through SSH. And it doesn't need the other server to run a FTP server!!!!
scp and rsync are both very helpful.
You are doing great, I highly appreciate videos of content creators like you. Sending Praise and Love to you, keep going
I learned about SSH by jailbreaking my Apple products years ago. Thanks for spreading the love
Not only did I really enjoy this, but I also learned a lot. Started from the creation of ssh to modern ssh, all while being super concise. Thanks a lot man!
I would really appreciate more videos like this
A bit calmer and more focused than usual.
use it every day, still learned something, the sign of good content!
Perfect video for me as an ongoing systems engineer. Thanks!
Just wanted to drop by and say your videos helped me get SEC+ certified. Thanks 👍
this is the content corporate youtube wants!
Very important tool that one just uses without stopping to appreciate what a nice thing it is!
watch out man youtube might decide that controlling another device from your computer is encouraging hacking.
Wow, this was really well done. Concise and to the point.
Thanks as always for this. Love learning about this kind of thing even though I already know a lot about tech didn't know much about SSH except is was secure thanks!!!
Ay G ion dub I didnt even know what u on till I saw this video thanks dawg u da real one G keep it up and stay up.
Just learned about SSH but very informative of the in depths, thank you mental outlaw
thank u, been dealing with some crazy stuff lately this helps
Pleasant narration. Keep up the good work. 👌🏻
You made me discover the -X argument for SSH, thank you, this is amazing
I knew a few use cases for ssh but what it is is often glossed over. Thanks for the video!
This vid looks nice and inoffensive, sure, but also it's useful and informative in its own right. Thanks for making it.
Thanks a lot, and the video has (almost) prefect timing personally for me.
I was wondering about how secure the secure shell is, and you helped me get rid of most of my worries. 👍🏻
Though, I'm still unsure if the initial credentials can be intercepted - if an attacker sniffs packets as I perform the very first thing: establishing connection (and, later, providing my credentials).
a good topic to follow would be to teach what are ssh tunnels and how to use them.
they are very useful for the management of local network resources and yet most linux users i talked so far never used them.
There's a specific reason for why compression is added last due to how compression before encryption introduces some recognizable patterns, even though it might even be detrimental to the achievable level of compression. But safety first! :)
I usually read stuff about this but i might start checking out more videos like these, look very interesting, Thanks!
And again, thank you for educating us, normies, my humble king. Love you 💕
Another really nice use of SSH is debugging software, especially interop software where more than one programming language and runtime is used. Got a lot of mileage out of it for debugging some C# interop recently when the existing debuggers for that just weren't giving low enough level of information. Kept an SSH session open monitor the specific portions of the logs involved on another machine but could have just as well done it from the machine itself since SSH works the same locally as it does remotely.
Why do you need ssh for that?
@@kreuner11 basically TeamViewer for command line
Yeah there are other options but watch or inotify over ssh works very well for this use case (monitoring logs)
@@satibel I mean, for local logs you can use tail -f
An here I thought I knew a thing or two about SSH. Nope. Learned a ton from this video. Many thanks!
Well-presented and engaging.
I laughed so hard at 2:38.
Well done, my friend, well done.
Very nice explanation. As a linux ssh newbie I found your explanation very informative. I followed ya on Odysee just in case the algorithym gets ya. . .
Those photos and graphics sure take me back!
This was a great video. You should do more of these. Maybe one about how asymmetric encryption is used to negotiate the connection and exchange the symmetric key?
Finally, useful video! This is better than biased rant like what Kenny usually did, tbh
The TCP/UDP water analogy was hilarious.
"Sniffing it.". Chef's kiss.😁
0:25 ah yes, SHH
everybody's favorite remote shell protocol
SSH is my favorite function of linux. It's the best way to manage a server rack all the way down to the router.
Thanks for the video Mr. Outlaw! Have a good one 😃
It's great to have you back!
Thanks for the video!
Outstanding video, great work Mental sir
please do more of these style of this videos along with your normal stuff!!
the matrix background behind the packet breakdown had me rolling
Thx. Its go to understand how what your doing works
Fantastic video! It was easy to follow and didn't' bore me at any point.
lol love the memes, I'm subscribing
That TCP UDP picture was spot on. Funny lol
Nice job explaining this
In 1997 I had a direct ethernet connection from my apartment to the university network. I used some aplication (can't remember the name) to get the X from the university unix computers to my linux computer. It was all unsecure telnet connections. We had hundreds of students with their computers sharing pics, music and whatever in their unsecure FTP connections. Damn, those were crazy times, haha.
Great explanation and illustration.
0:30 SHH graphic
Damn how do you put out so many vids. My fave channel!
Very informative
I recently just installed bitvise to host an ssh server for file sharing, works great, I recommend that if you Wana host ssh on windows
Good evening, Mr. Outlaw. Any chance you could do a video about port forwarding? My suddenly stopped seeding and supposedly my port is not forwarded. I'm too smooth-brained about networking to figure it out properly.
Port forwarding is done on your router and might be called something different depending on what router you have.
There's a website that breaks it down pretty simply.
Also: on some ISP supplied routers, it's very difficult or even impossible to port forward. I ended up buying my own equipment because of it.
@@whitewolf262 Yeah, on my sky router you need to pay for static ips and port fotwarding
@@sunglocto Thats insane you would need to pay for static IP's! Next thing to happen is force /30 instead of the standard /24 for the subnet.
@@tworiversfolk923 in the last 10 months i took two networking classes at my university and now i know what that means!
I've used Linux since more than 12 years ago, however I've never read how SSH works. Thank you for making this!
Nicely put, thanks.
The first time I heard about ssh I remember saying: Surely I should abuse it
Do one on the Nym network. They use sphinx packets like the lightening network, reorder the packets, use decoy traffic and adjustable timing delay to defeat timing correlation
Hey Mental Outlaw!
What's your opinion on Godot? I'm jumping from Unity to Godot because it's free and open software and it runs better on Linux than Unity.
Thanks!
I’m basically a boomer, with only enough computer smarts to be safe. I don’t normally really care about the minutiae of computers. So why do I really like your videos explaining it?
thank you for the video its really good could you make a video talking about ssh tunneling?
I was looking for a good explanation of the protocol yesterday, get out of my walls
This video is outstanding and packed with knowledge, but is no one going to talk about the Nagisa cameo? MentalOutlaw trutly is a man of culture.
this is the type of information that needs to be taught in school
Haha you wish. They aren't even teaching standard stuff that every single person will have to know. The school system is a failure in everything but the intention behind it.
American schools don't want to mold utilitarians, they want lap dogs.
@@ghosthunter0950 absolutely, but there isn't a whole lot we can realistically do about it
It already is lol
Thanks bro🤝
Bro explained this better than all my instructors 💀
Great explanation! Thanks
I never know if I should expect some useful tech info, or how to cook chicken...
Happy either way. 🖥+🔑+🖥 = ⚖
0:25 it says SHH on the graphic, instead of SSH ^^
You could have mentioned scp which allows file copies between hosts via ssh, and is super useful for those times you want to move files but can't be arsed setting up nfs.
Oooooh and authorized_keys versus password authentication, once you have a key you can zip between loads of hosts without ever having to type your password again :D
What I hoped to learn (which I can't find anywhere) is how do both parties exchange keys without outsiders listening in which will allow to however listening in on the key exchanges to decrypt everything.
I know I can read how X11 works on Wikipedia, but having Mental Outlaw explain it would be way cooler
Could you possibly do a video on setting up X11 remote login? Akin to what we see in universities where you have a dumb graphical login page and it starts and connects to a session running on the server.
Great video. Just wanted to say that websockets also use TCP
In simple word.
The main afocus on 2 keys..
Public key send on remote machine then the key will match the the Linux remote connection established..
This is simple way to understand....
Suppose access denied then check on sshd configuration file..
Very good video man, thanks
Doesn't terminal multiplexing refer to having a single shell instance spawn a bunch of different shells? Example I'm used to is making a single SSH connection to a remote and then opening screen or tmux on the remote
Do you have a video explaining what proxies do/are and the different types?
You can do X11 forwarding on windows if u download an X server for windows
I'd love to know more about how terminals/shells work on Linux in general, remote and local.
SSH is amazing, especially ssh tunneling. Saves so much headache.
great video. thank you
Wow. This is the perfect SSH primer. -- a Grey Beard who would have picked you up on the tiniest mistake, but found none
very helpful, thanks :)
Nice video ! I still don't quite understand how the encryption key is shared between the sender and receiver.
please make a video on the vulnrabilities of the xwindow system
Great Video
I really like your videos
Hey did you create that table at 6:14 yourself? Or did you get it from somewhere
How do the client and server know how to use the same encryption/decryption methods? Is that info sent, and what stops a man-in-the-middle getting that info then intercepting packets unencrypting them and then reencrypting them? 😕
