Key Authentication for PuTTY and WinSCP 

That looks very useful. Thanks for mentioning it

There can be various reasons so here goes... If the server refused the key chances are the public key has not been copied to it or it isn't in the right place You have to make sure the public key is associated with the user account that's logging in There's no point logging in as Jane for instance if the key was uploaded to John's account Or maybe WInSCP isn't using the correct private key when it authenticates or isn't using one at all so you need to check it's configuration And do make sure the correct key pairs are being used

Applications like Putty and WinSCP are configured with the key as part of the stored session so there is no directory structure as such But as BahadirM pointed out, Pageant is a useful tool for managing SSH keys It's supplied as part of the Putty and WinSCP packages and works with both Putty and WinSCP

Thank you for the feedback. It is really appreciated. And I'm glad to hear this was a useful video for you

Thanks for the feedback and glad to hear the video helped

There can be many reasons for a network error so unfortunately I can't say what the problem is

@@TechTutorialsDavidMcKone okk thanks

To use something like WinSCP you would need a VPN service which is beyond the scope of this video Assuming this will be over the Internet, you could also use a shared cloud service like DropBox You can then both upload and download files using the same account There are other providers and it really depends on how big your files are Each provider offers different storage amounts for free but charge for amounts above that

@@TechTutorialsDavidMcKone what about something like a source and destination, I don't want to complicated to much, something like point to point or synchronization, I don't know if I said it right, I'm not a IT guy, any other advice will be appreciated

@@carloscastroquintosa3598 I haven't used WinSCP for that purpose but there are details to be found here winscp.net/eng/docs/task_synchronize_full As long as two computers can reach other that should work

Good to know the video was useful And thanks for the like and sub

Thanks for the feedback and good to know the video was helpful

Did you upload your public key and store it in the authorized_keys file for the user you are logging in as? Have you configured PuTTY to login with that user account e.g. fred@192.168.1.1 ? And have you configured PuTTY to use the correct private key?

@@TechTutorialsDavidMcKone i aploaded it but not worked i want to configure ubuntu 20.04 server on windows i used vmwareworkstaion16 using pUTTY but not work i dont know why Permission denied Please help me {passeword access denied}

Check the permissions of the authorized_keys file As well as being in the user's .ssh directory, the user that is logging in needs access to it So if it was created by the root account for instance then it won't work

@@TechTutorialsDavidMcKone Thank you for the explaining Do u hav any video about that

I don't have a video but if you login to the console and change to the user's .ssh folder you can change the file permissions sudo chown user:user authorized_keys Although you'll need to replace user in that command with the actual user name

Thanks for the feedback, always appreciated it
