That configuration stanza expects to find your private key in


but you said you copied it to your desktop. Did you *move* it to your
Windows desktop, so it is no longer in ~/.ssh/id_rsa2?

It's trying to use ~/.ssh/keys/frewlynx.rsa as the key. Is there more in
your ~/.ssh/config file that specifies this? Or maybe in
/etc/ssh_config? Maybe a "Host *" stanza somewhere before your "Host f1"

You can get the ~/.ssh/config file out of the way to see if you can get
this to work:

$ SSH_AUTH_SOCK= ssh -F /dev/null -i ~/.ssh/id_rsa2 \

If that works, the problem is in your ~/.ssh/config (or possible
/etc/ssh_config). If that doesn't work, check the -vvv output again to
see which key it's trying to use.
