[arm-allstar] Trouble with Supermon

[Andy KB7B]

Tony,
You can also add another account and easily disable root logins 
for ssh making all attempts at the root account fail.

While some people would criticize such alternate ports for wks 
(well-known services) as "security by obscurity", it does work.

I had a repeater owner ask for my help, as one of his irlp nodes seemed 
to not respond to ssh client requests; he couldn't log in remotely. It 
was difficult, but I eventually found a prompt. I immediately looked at 
/var/log/* and found some very large syslog files. Looking at their 
contents showed an ssh attack on port 22, so I changed the port to 
something in a different range, re-started the sshd and the problem stopped.

Using simple system tools such as grep, sort, awk, uniq and wc, it was 
easy to find that > 3.7 million ssh attempts in 4 days from 4 east-Asian 
IP addresses had essentially crippled the system.

It did speak well for his choice of passwords though.
