[HamWAN PSDR] Recently connected... Now being attacked?

[Jason Maher]

Hi folks,

I have recently connected to the PSDR from my QTH in Suquamish via the 
Capital Park node. My Metal 5SHPN is fed from a Puynting 31dBi Grid 
antenna. I have a 16.2 Mbps connection at 21.4 Kilometers!

My concern is that it appears that someone is attempting to log into my 
router as root via SSH. There are multiple log entries every day citing 
"login failures". A whois on any of the IPs show up as originating from 
China.

A few examples:

58.215.56.110
120.105.81.190
49.203.248.133
202.119.236.121
95.211.8.134

I have applied the suggested scripts to blacklist an IP after several 
failed attempts. I also have a hardware firewall between the router and 
my LAN.

Are these just normal internet hacking attempts from bots, or is there 
something else going on?

Thanks!
