i want to remotely ssh to my home server, and I was wondering if I could just forward port 22 with disabling password login and use pubkey authentication will be safe enough?

If you are going all out, may as well add hosts.deny and hosts.allow.

Add port knocking, if we go all out, let's go all out!

Easy to do with known internal networks.

Difficult to manage when roaming.

Absolutely, just sometimes people forget those tools even exist. Of course, you can easily do the same thing with firewall rules as well.

Also, that was a great tidbit about the pam email notification on successful logon. I haven't seen that one before, thank you!!
