It's probably good practice to regenerate them pretty frequently. I did a brief audit of my /var/log/auth and noticed an increased number of ssh-scans. From a simple regional ISP, 4 a day seems pretty excessive. Of course I've got my honeypot set to give them 4 shots to log in before rejecting them for good, so I'd love to know how much they'd be hitting it if they were trying to brute force it.

I don't have any linux servers at home anymore and I'm not responsible for any professionally, so I haven't looked into the issue other than the basics.
