This is probably an idiotic question, but I'll try and provide as much information as possible. If you need any extra details, then please let me know.
I have a Mac running Ventura and an AlmaLinux virtual machine running in VMWare Fusion Pro 13. AlmaLinux is version 9.1.
First I created my SSH keypair on macOS:
ssh-keygen -t ed25519 -f ~/.ssh/localdevonly
Then I made a config file in ~/.ssh/config also on macOS.
That file contains this:
Host localdev
HostName 172.16.91.137
User simon
IdentityFile ~/.ssh/localdevonly
Then I uploaded the SSH public key:
scp ~/.ssh/localdevonly.pub simon@localdev:/home/simon/.ssh/authorized_keys
I changed the permissions on the authorized_keys file in AlmaLinux:
chmod 444 ~/.ssh/authorized_keys
Then I added the SSH key to the SSH Agent on macOS:
ssh-add ~/.ssh/localdevonly
Then I try to login from macOS:
ssh localdev -v
Which gives the following output:
OpenSSH_9.0p1, LibreSSL 3.3.6

I have no idea how I can fix this problem. I'm stumped. If someone could point me in the right direction I would really appreciate it!
