After that check from which ip it was logged in. This probably would be ip of the exit node.

Re: [tor-relays] Feedback wanted: letter to my university's library
by Alison Macrina 08 Oct '17

Hi AJ, Thank you for supporting Tor! I think it's a great idea to try to work with your university library to run a relay. I run the Library Freedom Project which helps libraries understand and use privacy tools (libraryfreedomproject.org) I can give you some advice based on my experience.

William's advice is good. You definitely need to begin by building a relationship with the library. Don't be discouraged by the amount of work this may take; the payoff might end up being a cultural shift wherein the library, university IT, and CS departments all work on this as a project together! You'll want to approach the library by showing that Tor is an excellent way to uphold the values of librarianship, which are privacy, intellectual freedom, and access. Really, be explicit about it; don't assume that they'll just get why you think it matters. Here's something I wrote about intellectual freedom + Tor Browser a while ago and you can borrow the arguments I've made: https://www.scribd.com/document/272919852/Alison-Macrina-The-Tor-Browser-an… As William said, libraries are mostly risk-averse, so you also need to be ready to answer their questions about legal and technical concerns. LFP has collected some resources to help with all of that here: https://github.com/LibraryFreedom/tor-exit-package/blob/master/resources.md. Before you email the university librarian, I'd start by talking to some of the regular academic librarians about your ideas and gauge their responses. Ask them if they've heard of the Library Freedom Project and feel free to send them any of our resources. See if they think the administration would be receptive to you offering a presentation about Tor to library staff (even better if you can make it open to students and faculty, too, because that can get you more support). You are welcome to adapt these slides for that presentation: https://libraryfreedomproject.org/allabouttor/. Make sure to show them this academic library that has used their Tor relay as a teaching tool for students: https://boingboing.net/2016/03/16/first-ever-tor-node-in-a-canad.html. LFP is fairly well known and respected in libraries and so if it can be beneficial to involve me further, I'm happy to assist! Alison

About relay size
by IPonU 08 Oct '17

08 Oct '17

Hi Tor list, I'm already running a small exit node (100Mbps bandwidth) and I'm ready to spend more money on it, so have a question for you guys : Is it better if I run other small ones (100Mbps too) or only 1 big exit relay (1 Gbps) ? What's best for the network stability/security ? Thanks a lot IPonU

anonymaid tor relays: MyFamily configuration
by nusenu 07 Oct '17

Hello anonymaid Relay Operator, thanks for running relays. Since you recently added more relays you are now in a position that can potentially harm tor users if you do not set MyFamily (torrc) on all your relays. Please have a look at you MyFamily configuration. https://nusenu.github.io/OrNetStats/endtoend-correlation-groups some more background: https://hackernoon.com/some-tor-relays-you-might-want-to-avoid-5901597ad821 Let us know if you need help with configuring MyFamily. thanks, nusenu -- https://mastodon.social/@nusenu twitter: @nusenu_

More recent rpm somewhere?

Hi folks, I'm running a few relays on CentOS 7 As I'm sticking to the ease of rpm distributions, I'm left behind on 0.2.9.10 from EPEL Does anyone know of another rpm repository with a more up to date version ? Thanks! Patrick

Blocking outbound 22 or no?
by AMuse 06 Oct '17

06 Oct '17

Hi all! I'm getting a number of ISP Abuse complaints around outbound ssh brute-forcing from our exit relay. I'm personally of the opinion that people should run fail2ban (or equiv) and get on with life and I generally ignore the complaints - but wondered, what are other operators doing? Is anyone exit-policy blocking outbound 22 to make the internet a kinder place? Is anyone refusing to on principle?

Re: [tor-relays] AU Relays and data retention
by Paul Templeton 05 Oct '17

05 Oct '17

Thanx Teor, I did speak to a lawyer and there is no requirement to retain any data if you run a node. It's treated as a VPN. My question that I sent was more about whether a service (non commercial service) was exempt. They don't delineate. Paul

AU Relays and data retention
by Paul Templeton 05 Oct '17

05 Oct '17

Hi All, I have asked the Attorney Generals Department about data retention and got the following response. If you run a relay/bridge here you seem to be exempt from retaining data. If your not an ISP and you run a service from home the ISP/carrier will retain the data though. This just general information. Regards, Paul UNCLASSIFIED Dear Mr Templeton Thank you for your enquiry to the Office of Communications and Cybercrime. I am re-sending our reply to your original enquiry that we sent on 12 September 2017 that seems to have not arrived. The extent of data retention obligations for your relevant service would relate to the extent to which elements of the data set “visible” to you. For example, where a provider does not have “visibility” of a customer’s IP address, it is likely that the IP address was assigned as part of a different relevant service. For example, if you have a record of the MAC addresses of users who access your network then this information must be retained for the required period. You are not obliged to retain the identity of the user if this is not information to which you have access. Whether the service is being offered on a commercial basis or is free is irrelevant in determining a service provider's obligations. In your email you noted that "The true origin of a connection and the true destination will never be known and there will be no way of obtaining the information. That also pertains to the ports used in the circuit and all data passing through the circuit will be encrypted." This sentence appears to suggest that you may be looking to offer some kind of an internet access service, in which case the destination is not required to be retained. Your reference to encrypted content suggests a VPN. If this is the case and this service is not operated you, obligations do not apply. Also, data retention would not require you to store the contents of the communications. Please do not hesitate to contact our office if you require further information. Regards Kerry Office of Communications Access & Cybercrime Intelligence and Identity Security Division T: (02) 6141 2884 The information contained in this email is intended as guidance only. It does not constitute legal advice and should not be relied upon as such. If you require legal advice, you should consult an independent legal adviser.

SSH Bruteforce Attempts

Hi, I have been running one tor exit relay for about 51 days and i recently got this abuse report: Good afternoon, Your Ip address (212.47.239.73) has been reported to us by profihost because it seems to have attempted to bruteforce.
