'host isbd.biz' returns the correct IP address for isbd.biz so why
does ssh not work using the name rather than the IP address?
Check your ssh client config file (should be at /home/chris/.ssh/config)
You probably didn't setup it for the host isbd.biz, or didn't put the
IdentityFile directive correctly.
The host entry in your case should look like this:
Host isbd.biz
HostName isbd.biz
Port 22
User chris
IdentityFile ~/.ssh/my-ssh-key-for-isbd-biz.key
But that's all default settings. Sites work without entries in
~/.ssh/config if the configuration is as you've shown above.
SSH client uses password authentication by default, so if you want to
authenticate with private key then you need to explicitly setup
"IdentityFile" directive or use "-i" command line parameter to select a
key file.
It is a good practice, at least for me, to explicitly setup separate
entries for each host, because different hosts might have different
keys, different ports and protocols, different users, different
encryption algorithms, etc.
If you have one-ssh-key-for-everything and always use the default port,
then you can use "Host *" directive to choose default settings, but
doing this might complicate things in the future.
