[opennms-bugs] Bug 782

[Derek Chen-B. <db...@cp...>]

Hi,
     I was looking at bug 782 and I think there may be a better way to 
poll SSH. I guess the issue is how far do we want to test the SSH 
connection. I looked at the code for SshMonitor and I think there are 
two issues:

1. We send an invalid client ID string (1.99 is only to be used by the 
server)
2. We don't need to send the ID string at all unless we want to move 
forward with key exchanges.

I think if we remove the code for us sending the banner that would be 
sufficient to test that the daemon is responsive. The only reason to 
send the banner is if we would want to test key exchanges, auth, etc, 
and that would involve creating or finding a java SSH library. Another 
possible change is that the default port is -1 instead of 22 and we may 
want to change the code to actually parse the returned banner instead of 
just doing a pattern match.

Derek
