Why do TorProject support the removal of RMS?

DISCLAIMER: I tried to find a more suitable list, but this one seems to be the closest to the topic. Tor Project is listed on https://rms-open-letter.github.io/ -> What is the motivation to sigh this letter?

The onion-location HTTP header is already tracked. Added propublica configuration in tracking as example configuration, thanks! One-hop non-anonymous onion service noted in tracking. OnionScan noted in tracking and recommended to be adapted as Continuous Integration. Personal tracking updated in https://github.com/Kreyren/kreyren/issues/60 peer-review appreciated. About the (D)DoS -> i was told that they are not a concern over onion routing due to the hard delay used for encryption. Can you confirm? Overall the (D)DoS is part of a threat model as FSFE has been (D)DoSed in the past where the main concern is Gitea as the static pages require an unreasonable amount of resources to be taken down atm. About Apache -> This is currently used by the webserver and needs to be implemented with priority in https://git.fsfe.org/fsfe-system-hackers/webserver-bunsen/src/branch/master… (currently tracked in https://git.fsfe.org/fsfe-system-hackers/webserver-bunsen/pulls/7) Any relevant information to the implementation is appreciated as i am currently struggling with making the TLS-over-onion work there where apache should strip the TLS when the website is accessed over onions. Any relevant information appreciated. About Nginx -> Currently not an option as the website is already using Apache. About EOTK -> I would like to implement this as an alternative configuration for system hackers to have a choice and do their research more efficiently and I assume that being a better implementation here as we currently want to onionize gitea service which based on my experience on https://git.dotya.ml requires changing of non-relative links within the webapp (which can be done in nginx/apache, but seems to be painful to maintain?). FWIW i am also considering decentralization for the static pages where the theory is to reduce the system load, make the websites less vulnerable to (D)DoS and make the websites to load faster as the webserver would be closer to the client in question. I am not aware of sane configuration for this over onions, but any relevant info appreciated. -- - Krey

Run onion on boot
by Amuza en Hackea 22 Mar '21

22 Mar '21

Hello, With software like dropbear-initramfs, cryptsetup-initrafs and others you can remotely unlock a server that has a LUKS-encrypted root partition. That is possible because there is an SSH server running in its unencrypted boot partition. I would like to have an onion service running in the boot partition too, that way I could remotely unlock the root partition without caring about ports, DNS, etc. How could I make it? Any advise, suggestion or step-by-step guide would be very much welcome, but please have in mind that I am not a developer... Thank you very much!

Referencing https://codeberg.org/Codeberg/Community/issues/50 Any relevant info to the implementation is appreciated (ideally submitted in the issue). TLDR: Upstream wants to outsource the onion router in VM to be maintained by 3rd party, i find that insane for privacy reasons. -- - Krey

Borg SSH could not resolve hosname
by anan 22 Feb '21

22 Feb '21

Hello! I'm trying to run BorgBackup through Tor for some small backups. Borg uses SSH for remote backups. I installed Tor on my local and remote computers. I configured an onion SSH service in the remote one, where my Borg server is. I can SSH the remote computer through Tor without a problem. To run Borg, in my local script I have BORG_REPO=ssh://iamusininthismessagethisfakeversion3onionaddressinsteadofmyrealone.onion:2222/path/to/repo and have "torsocks" before the "borg create" command. That does the job, the backups are done, however I am getting some name resolution error (please see below). Do you have any advice? Thank you! ------ ERROR torsocks[]: Unable to resolve. Status reply: 4 (in socks5_recv_resolve_reply() at socks5.c:677) Remote: ssh: Could not resolve hostname iamusininthismessagethisfakeversion3onionaddressinsteadofmyrealone.onion: Name or service not known Connection closed by remote host. Is borg working on the server? terminating with error status, rc 2

The problem of finding hidden Tor service after server restart
by Mariusz Otlewski 01 Feb '21

01 Feb '21

Hi All, I have several Raspberry Pi with hidden Tor service - I use this to connect to Raspberry over ssh. It works very well. I noticed that after restarting the raspberry, I have to wait a while for the hidden service to be found in the Tor network again. It's okay if I wait a minute, but sometimes I have to wait 5, 10 or even 15 minutes before the .onion address is found in the Tor network and I can connect to it. While waiting, I have a message in TorBrowser: *Onionsite Not Found*, in Torify: *Host unreachable* So I have a few questions. What determines the time after which I can find a hidden service on the Tor? Is it possible somehow to force a faster propagation of the availability of .onion address on the network? I've done a lot of testing but it looks very random. Could you please help clarify this point? Best Regards Manieck

Onion-routing of The Free Software Foundation Europe
by Jacob Hrbek 22 Jan '21

As a member of The Free Software Foundation Europe (web team) [<https://fsfe.org/>](https://fsfe.org/) i would like to formally request help with implementing onion-routing for our websites and gitea instance. The current effort is being tracked at https://git.fsfe.org/FSFE/fsfe-website/pulls/1756 with my public tracking on https://github.com/Kreyren/kreyren/issues/60 where any relevant information is greatly appreciated! -- - Krey
