Ya, my mistake, I wasn’t clear. I don’t mean that sshd doesn’t log if it’s on a 
different port, I mean that only the worst bots won’t find it, cutting down on 
the amount of noise in the logs. If ssh is configured correctly (disable 
password, 2fa, keys etc.) password attempts are just noise.

Using an obscure port only prevents attempts being logged, nothing else. And if 
you’re going to use an alternate port, pick one under 1024. Make it so an 
attacker needs to be root before they replace your sshd process.

[tor-relays] Relay bandwidth accounting

2018-06-17 Thread Sean Brown
I just set up a new non-exit relay and in going through information to set up, 
I came across the T-shirt for contributing and in addition to running for 2 
months it says "if you're not an exit but you average 500 KBytes/s traffic."



What would be the best way to keep accounting of the traffic my relay is 
passing? I know of the metrics.torproject.org, is that all the project would 
need?
