I have a fairly high bandwidth exit node running for about a month

now

that I'm having difficulty keeping off of the

http://cbl.abuseat.org/

blacklist and have been informed of this listing by the VPS

provider.

The relay is running with a reduced exit policy -- and additionally

I've

blocked common mail ports, etc via IPFW so I know that no spam is actually being sent out of the relay. Still, various botnets

connections

are connecting to abuseat.org botnet sinkholes via port 80 Command&Control connection attempts. I'm at a loss at how to stop

this

or somehow detect and filter botnet traffic.

I've informed the VPS provider that I'm on top of it and have the machine configured to not actually allow this sort of malicious

traffic

out and they seem to be generally happy with that explanation, but

a

better solution if one exists would be appreciated.

Thanks,

Julian Plamann

Don't know if this will help, but maybe:

ExitPolicy reject 85.159.211.119 # Cryptolocker ExitPolicy reject 212.71.250.4 # Cryptolocker ExitPolicy reject 54.83.43.69 # Cryptolocker ExitPolicy reject 192.42.116.41 # Cryptolocker ExitPolicy reject 192.42.119.41 # Cryptolocker ExitPolicy reject 198.98.103.253 # Cryptolocker ExitPolicy reject 208.64.121.161 # Cryptolocker ExitPolicy reject 142.0.36.234 # Cryptolocker ExitPolicy reject 173.193.197.194 # Cryptolocker

In general, I see complaints about abuse from the exit relays we run due to someone using Tor to try to exploit remote web server scripts and databases and the like. I don't think there's anything that can be done about it? I would say that it's just part of what you get coming out out of Tor exit nodes.

If anyone else has any better advice feel free to correct me but, I think it might be accurate to explain to the upstream that Tor exits will generate certain kinds of abuse complaints as part of normal operation. They open proxy web-related ports out, and some people abuse Tor for web hacking types of activity.

I would say that it is normal for Tor exits to live permanently on certain kinds of blacklists. They do not need to be on the spam email related ones (reject *:25 and other email ports), but they will land on other types of blacklists, and I don't think it can be helped.
