Yes, it's normal. Just people scanning for SSH ports to attack. What I did was take the IANA IPv4 address space list[1] and add firewall rules to drop packets to port 22 coming from /8's that I would never connect from. I'm in the US, so it made sense for me to drop connections from subnets assigned to RIPE, APNIC, etc. It didn't eliminate the problem, but it reduced the connection attempts considerably. 1. https://www.iana.org/assignments/ipv4-address-space/ipv4-add... |
