When ever i try "ssh -T [email protected] " OR "ssh root@" OR push my branch it shows me this error

So i got the solution,I completely messed up the ssh_config and sshd_config files... Man pages for sshd_config (the server-side config, which includes the AcceptEnv, AuthorizedKeysFile, Subsystem, and UsePAM keywords) vs ssh_config (the client-side config, which doesn't have any of those -- although it does have some related ones, like SendEnv, SetEnv, and SessionType ).

I took the latest files of ssh_config and sshd_config from github and also updated the config file by entering...

sudo nano ~/.ssh/config

and updated my host settings

CodePudding user response：

This may look similar but there is another issue, files are different ... is there any way to reset my whole ssh folder ?

First, as explained here, you can add any setting you need for sshd_config to a file in /etc/ssh/sshd_config.d/*.conf.

The file 100-macos.conf comes with MacOS Monterey.

Editing that file would likely get reverted upon the next patch, so it is best to leave it alone, and add a new conf file if you need custom settings.

Check if Time Machine is activated to restore the original content of 100-macos.conf (unless you can upgrade your OS, which would reset its content)
