Thanks. I just could not see how Fail2ban would work on an ORport. What log would it look at? What criteria for the jail? The fai2ban on my non-tor VPS does not yet work with IPv6, which is partly the nature of IPV6 rather than a programming issue. I did not realise IPV6 was ignored until a weak email account was found. So I firewalled off most IPv6 ports instead.

Gerry, At this point I have no working scripts for Tor/fail2ban. Be happy to share if they ever materialize. Fail2ban is sorely lacking documentation--or at least I can't find detailed docs. I downloaded fail2ban on current debian and ubuntu VPS and got different version numbers--none were the current release. Stay tuned or give a hand. -potlatch

Can we have your fail2ban scripts for the OR port? The jail and rules?

passage. If you're trying to prevent too many connections, you can adjust the DoS torrc options: DoSConnectionEnabled 1 DoSConnectionMaxConcurrentCount 1 DoSConnectionDefenseType 2 If that works, try adjusting DoSConnectionMaxConcurrentCount a bit higher: 10 or 25 are good values.
