tor middle relay issue
by theyarewatching 22 Jul '24

22 Jul '24

I have had two ubuntu based tor middle relays fail.I am using a proxmox server and have tried both ubuntu server 20.04 and a fresh download of ubuntu 24.04. I follow the tor website install instructions. The results show the same no matter what version of ubuntu. "failed to start Tor(a)default.service. This is the same result with the original install and a brand new VM install on Proxmox. Any input would be greatly appreciated Thank you SDS

OOM at relay with small RAM if statistic configs are enabled

Regarding to https://gitlab.torproject.org/tpo/core/tor/-/issues/40958 I do wonder if that issue happened for stable Tor versions too - I do run myself git HEAD only. FWIW at my bare metal relay the RAM consumption per Tor process decreased by about 0.7 GiB. -- Toralf

Hardware sizing for physical exit node
by Osservatorio Nessuno 10 Jul '24

10 Jul '24

Hi everyone, we are planning to get some hardware to run a physical Tor exit node, starting with a 1Gbps dedicated, unmetered uplink (10Gbps downlink). We will also route a /24 on it, so we will have large availability of addresses to run multiple instances. We have been running a few exit nodes so far, but never on our own hardware. Which is the bandwith limit per core/Tore instance? Or what can we expect to be the bottleneck? Due to some other requirements we need for some experiments (SFP ports, coreboot support, etc) we can mainly choose between these 2 CPUs: Intel i5-1235U Intel i7-1255U The cost between the two models is significant enough in our case to pick the i7 only if it's really useful. In both cases with 32GB of DDR5 RAM (we can max to 64 if needed, but is it?). Should this allow us to saturate the uplink? To summarize, with this bandwith, this hardware and a /24 how many Tor exit nodes should be ideal to run considering that each of them could have their own address? Thanks!

Seeking Advice on Running Multiple Tor Relays or A Bridge
by Alessandro Greco 07 Jul '24

07 Jul '24

Hello Tor Community, I have some experience running a Tor relay, and I am now interested in setting up another one. I plan to do this using my home internet connection, which is an FTTH line with bandwidth up to 2 Gbps. I have read that it is possible to run multiple relays on the same node, but I am unsure how to configure this. Additionally, I am curious about what would be most beneficial for the Tor network today: a highly resilient bridge or multiple relays managed from the same node? Is it feasible to operate both at the same time? This is probably not the best idea since the bridge's IP address would be public, right? I am looking for guidance on the best course of action to support the Tor community. Thank you in advance for your assistance,Aleff.

For what it's worth, in addition to my Tor Bridge Relay, I also run two Snowflake Proxies on my home LAN. Malcolm On 6 July 2024 19:14:23 GMT-03:00, "Gary C.
