On Windows cmd you can use ssh by default!

I noticed that it doesn't have the cool shortcuts that Linux does though. For example ssh-copy-id which is pretty annoying.

I have ssh installed on windows (I can just use it in the terminal) and I can't remember ever having to install it so windows users: maybe you don't even have to install it. Just check by typing ssh into the command prompt and if it gives no error, it is installed.

In Windows we use the terminal (cmd) or PowerShell and we don't need Putty at all. It's 2 years or so, since Windows natively supports ssh connections through PowerShell.

Jay, this was very helpful to me in getting RSYNC working to move data from Linux to Linux. I looked at lots of other video and written tutorials, got confused enough to hit lots of subtle roadblocks along the way. What you prove here is this topic is not that complex if you stay focused on the essentials.

Windows 10 and 11 do include ssh installed by default. Just open cmd or powershell and type ssh. The config files are located under C:\Users\\.ssh. No need to use Putty anymore.

Windows 10 has a built in option to install the OpenSSH client from Windows Apps and Features. It would be cool to show using that client as it is accessible from the Windows cli and ssh-keygen works from there as well - storing it in the Windows equivalent user/home folder/.ssh structure. However, it doesn't seem to work from there when using the ssh connection - unless I'm setting it up wrong - but that's why it would be nice to see a video using this method and going through setup - using the native Openssh tools.

To anyone fairly new like me, don't forget to leave the id_ at the start of the filename. Pretty sure that's probably something I was supposed to know but it just caused me an hour or two of headache before realizing... If it isn't common knowledge or something you're supposed to do, it at the very least appears to be default behavior with Windows' OpenSSH implementation. It appears like it won't try user generated keys upon connecting unless you have id_ at the start of the filename.

Hi great video, but I'd like to see tutorial with Ed25519. Today, the RSA is the most widely used public-key algorithm for SSH key. But compared to Ed25519, it’s slower and even considered not safe if it’s generated with the key smaller than 2048-bit length.

hi, thanks a lot for your useful TV 👍 i've watched several of you're videos and i want to thank you for the help you're providing to the rookie i am 😄 it's my fist message here to ask for the correct command when using a another user, if wanting to do this for several users, and use a different port than 22 (which is 'the wrong way to do it' ; )

I do have a number of Raspberry Pi devices on my home network plus manage an Ubuntu system remotely for a friend. Initially I confused myself a wee bit by actually naming the private and public keys but strangely it all worked fine, seems the actual name of the file is irrelevant, just the contents important.

Very good video, thanks you. Just wondering, if I followed your instructions and uploaded my public key to a server does that mean anyone with access to that public key can access that same server?

@inuyashacoolieo Жыл бұрын

No, because the private key is stored on the client machine. You created the key pair on your machine and then added just the public key to the server (using the real password for the server). So you still need to know the login credentials for the server to set up the key pair for the first time. Even if someone else had the public key it would be useless to them.

I followed the advice but it hasn't worked :/ when I try and ssh in it still asks for my password. i can see the public key in the authorized keys file. Do I need to make changes to ssh_config or something?

@disasterarea9341 4 ай бұрын

I managed to get things working by redoing the ssh-keygen process without specifying a file when prompted with "Enter file in which to save the key (/home/user/.ssh/id_rsa)" I noticed when doing ssh -v user@host, there were a number of lines of the form Will attempt key: /home/george/.ssh/id_rsa Will attempt key: /home/george/.ssh/id_ecdsa ... but did not check the key I had made. I assume there's some config file somewhere which tells it what keys to check - and you'd have to add a new entry if you save your key in an unusual place. it's so easy to trip up :)

You shouldn't show your public key just like you shouldn't show your password. If someone knows your IP and username, then the public key is akin to a password (unless you also use a password, then they can attempt to brute force that).
