So I setup ssh on a server so I could do some work from home and I

What's a good way to deal with this?

1. Change the default port
2. use only SSH protocol 2
3. Install some brute force protection which can automatically ban an IP
on say 5 / 10 failed login attempts
4. ONLY allow SSH access from your IP, if it's static. Or signup for a
DynDNS account, and then only allow SSH access from your DynDNS domain
Fail2Ban is a good brute force protector. It works in conjunction with
IPTables to block IPs that are "attacking" for a said duration of time. :)
