The OpenSSH client tries keys in a certain order. running `ssh -vvv
<host>` will show you the order.
You can change the order with the use of IdentityFile in your SSH
config file. OpenSSH will try keys in the order specified by
IdentityFile's in the config file.
$ cat ~/.ssh/config
Host *.fsffrance.org fsffrance.org
User noloader
Host *.opencsw.org
User jwalton
Host *.home.pvt
User jwalton
Host *
User jwalton
IdentityFile ~/.ssh/id_ed25519
IdentityFile ~/.ssh/id_ecdsa
# IdentityFile ~/.ssh/id_dsa
IdentityFile ~/.ssh/id_rsa
Protocol 2
PreferredAuthentications publickey,password
OpenSSH will parse and expand the tilde (~).
