Exits behind a next-gen firewall? Opinions please
by Jesse Victors 11 Jul '14

11 Jul '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hey guys, I've been running some exit nodes for some time now, and they're doing well. They've burned through many terabytes of bandwidth, and thanks to Tor's recommended reduced exit policy, complaints have been minimal. Clearly the vast majority of the Tor traffic is not malicious, but I have received some reports from other companies and from my ISP of hacking attempts: SQL Injection, XSS, botnet C&C, basic things like that. My ISP now tells me that they could reduce the reports even further by routing the exits through a "next-generation firewall" which apparently can detect an obvious clearnet attack and drop that connection a few milliseconds after the attack occurs. I don't know how the firewall works in detail, perhaps it has the ability to drop a specific connection rather than drop all access to the destination IP for a while, nor do I know how it would interact with Tor's traffic patterns out of an exit. I'm posting here for opinions. My question is, is this a good idea, and if so, any advice? Does anyone have any experience with such a setup? - -- Jesse V. /PGP 0xC20BEC80/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQF8BAEBCgBmBQJTvyBdXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQxMjgyMjhENjEyODQ1OTU1NzBCMjgwRkFB RDk3MzY0RkMyMEJFQzgwAAoJEK2XNk/CC+yAbrcH/2IG+Z6jVNhj9j5EpvHkzl0V XXn1Fbkw7EV8P+cRfQwgmouGQZ4IhuD9QP21ql7wvAIHIkIeaKNtXDb1jELL6F3z b1r8IRm2ePOJNl3X3m/5NIbqbz2utdaRqLglo9vhmr26zx+VMJBfzE5AvVLUhq9B CzBYjJujJcASH9KWN08hhjxu81mS0xUmUnFJIfoV7sJto2y3EmJuCQXauMBsxDsf 1rNQFcoxfKS1YI1v1MdBA/xHNO+UaLUShFQR1mw7RIW8jaPNLTGE157nPXMq9xiX nTzOjkgZ3RI+qrmhcjwJEcV9BAAO86C6HXJvflbhkVPZkCBB43LFCeUKf+SGRR4= =98Se -----END PGP SIGNATURE-----

Parliamentary inquiry about legal status of running Tor in Austria
by MacLemon 09 Jul '14

09 Jul '14

Hoi! This is a cross posting tor-talk/tor-relays (Due to the current attention on the recent events in Austria. Thanks for understanding.) Niko Alm (of Austrian political party NEOS) has made an official parliamentary inquiry to the Austrian ministry of justice about the legal status of Tor. Blog posting: http://alm.at/tor/ (in german language) Inquiry: http://neos.eu/klub/20140708_AF-TOR-BMJ.pdf (in german language) In theory running a relay/exit _should_ be covered by Austrian E-Commerce law §13. It's just not legally proven that Tor also falls under the definition of a “communications network” from a legal point of view. Technically everyone would certainly agree that this is the case. From what I understand the goal is to get an official statement by the Austrian ministry of justice that Tor falls under the legal definition of a communications network. Which would mean, that Relay-Ops are not liable for the traffic passing through their relays given they do not initiate the traffic by themselves do not select the recipient of the information do not select or alter the transmitted information This includes caching. Austrian E-Commerce law, §13 legal text (german language) http://www.jusline.at/index.php?cpid=ba688068a8c8a95352ed951ddb88783e&lawid… Best regards MacLemon

Unprompted HUPs
by kingqueen 09 Jul '14

09 Jul '14

hi, Checking the log of my relay, I see that sometimes it reloads its configuration from what it says is a HUP signal. An example: "06:40:57 [NOTICE] Received reload signal (hup). Reloading config and resetting internal state." I don't understand, as I was asleep at that point and didn't interact with the relay or the server at all, I haven't set up anything to automatically issue a HUP. Does Tor automatically trigger its own HUP every so often? Thanks --- This email is free from viruses and malware because avast! Antivirus protection is active. http://www.avast.com

Google captcha
by kingqueen 09 Jul '14

09 Jul '14

Hello Since running a relay, I have frequently had the notice akin to "Google has detected unusual activity from your computer or network" and had to do the captcha, when I have connected via the server that the relay is running on; both by Chromium over VNC and by Firefox over OpenVPN. The thing is, I am not, and have never been, an exit node. I was a middle node and am now a guard node. So I am somewhat confused as to why Google is getting unusual activity from my server? I guess it could be a coincidence and somebody else from the server farm has tripped it, but it seems a remarkable coincidence, as I have run the dedi for nearly a year and didn't have the Google notice until after the Tor relay was started in the last three weeks or so. But I don't understand how being a Tor relay could have tripped it, as I've never been an exit node. Thank you --- This email is free from viruses and malware because avast!

"excessive bounces" on tor-relay list
by Kali Tor 09 Jul '14

09 Jul '14

Hi, I keep getting the warning once in a while that there are excessive bounces from my email address and that my membership to this list has been disabled until I click on a link to re-enable it. Is there any reason why something like this would happen? I use yahoo mail, as you can see but I just don't know why Yahoo Mail would bounce any message. I have not received any warnings from Yahoo about such an action. Thanks, -kali-

Re: [tor-relays] different torrc and fingerprint when rebooted

In my experience yes, you should be able to move those files to the current working directory and it will just work.

Re: [tor-relays] Reliable way to gauge tor throttling?
by tor＠t-3.net 09 Jul '14

09 Jul '14

Assuming the Tor service is running on a dedicated host, you could use an SNMP-aware switch and query it with Cacti for graphs on the switchports, or maybe run an snmpd on the node and use Cacti to build graphs against the node's ethernet card stats. http://www.cacti.net . It can also be pulled down as an RPM from some repositories, such as epel.

Re: [tor-relays] Hits againast GFC hex--string fingerprint in IPTables yesterday
by tor＠t-3.net 09 Jul '14

09 Jul '14

This has happened again, to the same node. The 4 hits came between approx. 16:39:57 and 16:40:27 EST on July 8. 4 offending IPs, one hit each: 1.50.251.122, 210.72.140.17, 119.4.5.55, 115.200.236.120 (they are all from China, per Apnic). They hit against the same hex-string rule as before.
