Onion Service Monitoring

Dear fellow Onion Service operators, I'm curios how you monitor the availability of your onion services? I implemented a solution with icinga2 check commands. It basically queries the onion service via torsocks and check_tcp command [1]. > > object CheckCommand "check_tor_onion" { > command = [ "torsocks", PluginDir + "/check_tcp" ] > timeout = 6m > arguments = { > "-H" = "$hostname$" > "-p" = "$port$" > "-t" = "$timeout$" > } > } This solution is kind of flaky and produces a lot of mail noise, even if I run it with large timeout value (360s), check attempts and retry intervals. Recently I came across the tool called hsprober [2], which looks like a more compelling option. though it requires a prometheus setup. Since it is a network, where connections constantly looses connections, I would like to know how you treat this flakyness. Regardless of which software stack you use, I'm interested in your concept for monitoring your onion services from the outside (user side) and from the inside (server side). And also which tools do you use. Thank you for any answers and opinions. Have a happy new year. shadow [1] - https://www.monitoring-plugins.org/doc/man/check_tcp.html [2] - https://git.autistici.org/ale/hsprober -- best regards | viele Gruesse, shadow(a)systemli.org receive my key: gpg --keyserver zimmermann.mayfirst.org --recv-keys 0x5C6B6ED4248C1F32

Matrix/Synapse as Onion Service
by shadow 10 Jul '21

Hey all fellow list members, does anyone of you has been able to set up Matrix / Synapse / Element as an onion service? There are are open tickets regarding this: * https://github.com/matrix-org/synapse/issues/5152 and also a Cloudflare level implementation: https://blog.cloudflare.com/cloudflare-onion-service/ But I wonder if anyone of you already set it up and what your experience have been with it. To me it looks like, that there are multiple problems and several layers (depending on your Matrix Setup). For example if you use the ansible roles for setting up matrix in a docker environment (https://github.com/spantaleev/matrix-docker-ansible-deploy) Have a nice sunday afternoon, shadow // systemli.org
