That sounds like an excellent idea. if the site nowot.com is available, someone could register it.

How's your relay doing? Reporting Bad Relays
by Matthew Finkel 08 Nov '14

08 Nov '14

Hi Relay Operators, A few months ago[0], we announced the bad-relays(a)lists.torproject.org mailing list and asked everyone to send reports to that list if they suspected a relay was...bad. We've already received many reports, so please keep them coming. We also want to ask all of you to use that list, as well. If at anytime you think your relay is no longer safe for use, please tell us. Roger tweeted about this yesterday[1][2], too. The Tor network exists because of all of you and we can only keep it safe with your help. Let us know if you have any questions. Thanks! Matt [0] https://blog.torproject.org/blog/how-report-bad-relays [1] https://twitter.com/RogerDingledine/status/530878388605423616 [2] For those who don't want to open Twitter: If your #Tor relay is stolen or you lose control of it, please report it so we can blacklist it: https://blog.torproject.org/blog/how-report-bad-relays @TorProject

That would not cover people who compile and use upstream Tor. Ideally, the Tor client could check for any system parameters it feels are critical before running, or simply delegate them and/or any parameters of lesser importance to platform specific guides on the Tor wiki. > On 7 November 2014 00:20, grarpamp <grarpamp(a)gmail.com> wrote: >> On Thu, Nov 6, 2014 at 8:52 AM, Philipp Winter <phw(a)nymity.ch> wrote: >>> >>> FreeBSD still seems to use globally incrementing IP IDs by default. >>> That's an issue as it leaks fine-grained information about how many >>> packets a relay's networking stack processes.

Re: [tor-relays] Adding relays with a click
by Nan 04 Nov '14

SiNA Thank you -- that looks like the script we need. Even though it was written for Ubuntu it should work just as well on debian. We probably can simplify it because every GoodCrypto server is already a tor proxy. Thanks again, Nan ----- On Nov 4, 2014, at 17:41:37, SiNA Rabbani sina(a)redteam.net wrote: > You mind find this script interesting: > > https://gitweb.torproject.org/tor-cloud.git/blob/ce98487e1174bff3a76c1f9f03… > > --SiNA GoodCrypto warning: Anyone could have read this message.

Adding relays with a click
by Nan 04 Nov '14

04 Nov '14

We're considering trying to make it a single click for a sysadmin to add their GoodCrypto server to tor as a bridge or non-exit relay. Any experience with anything like this, especially responses from sysadmins? Nan GoodCrypto warning: Anyone could have read this message. Use encryption, it works.

CMU exit node IP address will change
by Zack Weinberg 02 Nov '14

02 Nov '14

CMU network operations has decided to move the Tor exit node that my group operates (tor-exit.cylab.cmu.edu) to an isolated subnet in order to minimize consequences for the rest of the campus network. For instance, apparently there have been several cases where third parties blacklisted the entire CMU IP space in response to malicious traffic from the exit node. This is currently scheduled to happen Tuesday (Nov. 4). The new IP address will be 204.194.29.4. I'm sending this message primarily as an assertion that nothing nefarious is going on, but also because I haven't had to change the IP address of a running node before and I would like to ask if there's anything in particular that should be done to minimize downtime. Thanks, zw
