forwarding port 22 safe? (alien.top)

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?

I would not do this, people port scan all the time and thats an easy one to look for. Try using an at home vpn like openvpn or in the very least change the ssh port to something odd like 6854 or whatever.

I have a port 22 ssh process that denies everything, and a separate ssh process on a different port that accepts logins as normal. So someone could obviously find the hidden one, but it won't be the apparently-functional one that they can hit day and night and never get any results from.

Fair enough. If you can run firewall rules then great. But opening up something like ssh to the internet is a risky risk. Cert auth is not a bad way to go in that scenario.

I agree entirely. The box I have this on is my piddle-around server. A long time ago I used to administer a medium-sized cluster of Linux boxes and they were all cert auth, and I wouldn't have had it any other way. Mostly, I think it's fun to see what usernames and passwords the scripts and bots and hackers try on my neutered SSH.
