I honestly just want to take a second to appreciate how well you explain stuff. If you were to make a course i would almost certainly buy it!
Recommending your channel to all my classmates at university!
Thanks man! I appreciate it.
Good video, I'm teaching myself SSH pretty much with UA-cam. I'll give it a try.
Awesome. I have a video that will drop in the morning about an application to help protect your ssh server.
finally got around to setting up ssh with the server I setup thanks to you! Greatest Of All Techies! The GOAT for real! Sharing so much knowledge on Linux through UA-cam! again thanks!
Awesome thank you!
Thank you! Your tip to be logged in to the server via cmd while beeing in powershell helped me. Thanks!
Glad I could help!
that was really good. I've heard this explained in so many different ways, but really heard you
Your channel is awesome thank you so much for all the time you spend in making them, you're a fantastic in the way you explain things were others make it difficult to understand. I hope you have a super weekend.
Thanks man! I try to keep it simple! 😉💪🏾💯
Thank you so much! This was really well explained. I'm new to Linux and I understood your video very well. Keep up the awesome content! 😃👍
No problem. I have a free course on my channel if you need more help.
Bro I just wanna say thank you. This is very helpful and very succinct.
the best video about configuring ssh on YT. well done dude!! Thumbs up and sub
Wow, thanks!
great tutorial! thanks for sharing your knowledge in such a useful way!
No problem bro! Thanks for checking my channel out!
Thank you so much Josh.
I just had my first linux instalation on my laptop.
The way to create and configure the ssh key on this operating system is new for me.
Your tutorial is fantastic and the way you explain all details are very good.
I just subscribe to your channel and set the bell notification on All
Respect and appreciation!
Mr. fumdfum
Glad it helped! Thanks for subbing!! I appreciate it!
Aswesome video bro! Just the one I needed. Thank you
No problem 👍
Yes! It worked!! Thank you 😊
Slowly setting up my home server. Thanks Josh!
Salute!
great video! thanks for the help
Good explanation. Thanks.
Useful, good idea to have good OpSec and lock down all your systems. If you're able to login with just an ip and password, a hacker can do it too. One tip for using nano is hit Ctrl+W and type in whatever you're looking for, so for example PasswordAuthentication and it'll take you right to it. Saves me a lot of time.
Great tip! I always forget Ctrl+W is the search! Thanks bro!
Great info. Thank you SIR!
Thanks!
From VietNam. Thanks pro
Awesome tutorial content!
Thanks man!!
Thanks for your tutorial but I have the question that
How to get a password at 5:51?
I have tried user password when sign in to the device but it not work
Another good one!! Need to setup an OpenVPN on my lab and see if yo can get in.
Thanks man! I got you. I need to do a video on OpenVPN too. I have one setup on a raspberry pi on my network as a test.
Really good video ❤️
A++ thank you thank you!!
You're very welcome!
Very well done video! Couple quick questions though. I have multiple devices and want to set up ssh from each device to the ssh server. When I create the ssh keys should I do so on the server and then send the public key to the device or should I be creating the keys on the device then sending the public key to the server. Also do I need to disable password authentication on each device?
Thanks! Yes and yes. Its best that you disable password authentication after you install the keys. Make sure you test it all before making the change in the SSH config. I've locked my self out of a remote server before. That is no fun. LOL
@@KeepItTechie Thank you!
great video!!!
Thanks
Can you SSH outside of your LAN network? Like SSH from my Mac at work to my Ubuntu computer at home?
Yes you can. You have to setup port forwarding on your router to point to your server. I talk about it in the video.
I can't believe you make this question. :)
hi bro..can we use the same publickey for differenr servers
Yes you can. Just copy to all the servers you want to connect to.
How to move file between 2 Ubuntu?
Actually the name of file is an variable the extension is fix. There is no option on scp that delete the file u just copy?
rsync is the most secure way of transferring files between Linux computers. It also has a delete option.
@@KeepItTechie how is the command line like?
I want create a script that automatically transfer the files to one macchine to other... In windows is easy but Linux performs much better
@@brunognoato8016 I'm currently working on a video of a application called syncthing. This will be perfect for the situation you are facing. You basically install it on both systems and setup the sync between two folders based on your settings. Otherwise I have a video on how to use rsync, that can help you accomplish the same thing. ua-cam.com/video/XCjK2nwmAmg/v-deo.html
so we need to use command on windows like this?*correct me please.
ssh -"ssh server keys"(SHA:blablabla) -b "ssh server ip"
and then write the pasword. like that?
Starts at 2:02
i tried to copy by ssh-copy-id but its showing connection refused
Check to make sure the firewall on the server isn't blocking port 22.
AM GETTING THE ERROR BELOW WHILE RUNNING IT ON JUPYTER NOTE BOOK
client_id = 11
ib = IB()
ib.connect('127.0.0.1', 7496, clientId=client_id)
THEN ERROR COMES OUT AS
ConnectionRefusedError: [Errno 111] Connect call failed ('127.0.0.1', 7496)
YOUR INPUT IS HIGHLY APPRECIATED
lost access to a remote rack server last week. had to rebuild.
Dang bro! What exactly happened? You should have been able to access the server directly to reset the SSH config. Was it on a cloud platform ie AWS, Azure, etc? No need to rebuild if you can get to it.
@@KeepItTechie it's hosted on a vps. the emergency console wouldn't work and support was confused. i had to act.
I got a question i dont have a linux client how can you do this with a windows client i used putty gen made the keys used ftp to copy the key over when when i try to connect it says Server refused our key
Sorry for the delay! If all else fails put the key on a usb and physically put it on the server, unless it's in the cloud. Let me know if this helps!
@@KeepItTechie yeah that's what I ended up doing that's the only thing I could think of as well
Just one question - i have tried generating with puttygen the keys (manually and I store the private key in my PC, and load in into Putty at log in), and paste it manually in the authorized_keys and it works...
but I want to do the same for a regular user as well (non-root)...
I have added the key code in the same file but I was unable to log in with my public key - 'server refused your key"... I have also tried adding the pub key code logged in via the regular user as well, so the root folder is /myuser/etc/ssh/authorized_keys but same problem.... not sure what I am doing wrong it's driving me insane :(
