Hello, Since 2 weeks I investigate in my whole homelab the cause of an issue. Let me explain it :

I experience slow network speed when accessing my services from outside (outside local network without a VPN to connect directly into it).

Context :

My local network is all in 1Gb, my ISP download and upload speeds are 500Mb each.

Setup :

Since a while I set up a Librespeed server to be able to benchmark speed to my homelab from everywhere. When doing a direct connection from GbE pc to server, I get perfectly 1000Mb (more or less) symmetric speeds.

I was running caddy to reverse proxy it, and basically when connecting trough the domain (therefore trough the proxy) locally I got 980Mb (Surely the overhead that is caused by https and having one more hope).

(And I need to mention that when doing fast[dot]com, speedtest[dot]net or even librespeed[dot]org speedtests I got roughly 500Mb symmetric speeds, my ISP wasn’t lying)

So for now all of it is okay and working as intended.

Issue :

Here comes the problem when doing a speed test to my server (so trough speed.example.com) from a friend computer (who got 450 and 400 Mb on librespeed[dot]org servers), he got around 100Mb download (so homelab upload) and 400Mb up.

Tried other scenarios, from my home (the same where is located the homelab), I connect to the internet trough protonVPN or windscribe (all free tier).

While I was getting around 300-400Mb from librespeed[dot]org servers. I was sometimes getting 7-8Mb from speed.example.com (my libre speed install).

Even when working better I only got something like 80 down and 200 up, better but I was always really lower than popular speedtests or just a bit that could be somehow be margin error (around 40Mb on 400Mb), but was always here, it was not able to get right speeds.

Potential issue with librespeed :

Thinking that librespeed was not working good, so I tried to make a file transfer in file browser service, (Tried going trough and around caddy), getting around 100-110MB per sec without any VPN, going down to 8MB when transferring from the VPN.

Iperf got the same results around 100Mb of transfer speed going from VPN instead of 500Mb.

Maybe this isn’t really clear but I’d be really happy and respectful if someone could help me with this. Feel free to ask questions. :)

EDIT : tried to use nginx but this was even worse as even locally the speeds are not stable at all (not able to have full gigs local speeds) But don’t worry this is an other problem I will maybe resolve later

And little question, does WAN 500/500 speeds means that I can use 500Mb up and down at the same time, or that I can only use 250 each a the same time?

I found about Usenet and the sort of "hype" relative to it and I wonder some stuff.

Maybe I'm a bit old school but is this process not against the spirit of piracy,

• be generous to share
• fight against censorship and DCMA takedown
• work in a decentralized way

Just wondered it, if someone wants to give his opinion

I need your opinion on this problem:

My personnal infos are on the web, is it better to try to have them removed or simply ignored it?

Basically I'm wondering if trying to remove it would not make me shine outside of the crowd more than juste leave it and act as simple citizen

And, warning, these infos are not compromising but they are personnaly infos

Hello, I want to install searxng without using Docker on my homeserver so I basically run the install script from the official documentation. Already tried to use the automatic script for setting up apache and it basically worked by exposing /searxng. But I would like to do something simpler as I like that apache would only expose localhost:80 (for example) to use a reverse proxy later to point to it. Just wondering how this configuration work and how I could do something that applicates to my use case :

Any help here? Thank you very much

This is again a big win on the red team at least for me. They developed a "fully open" 3B parameters model family trained from scratch on AMD Instinct™ MI300X GPUs.

AMD is excited to announce Instella, a family of fully open state-of-the-art 3-billion-parameter language models (LMs) [...]. Instella models outperform existing fully open models of similar sizes and achieve competitive performance compared to state-of-the-art open-weight models such as Llama-3.2-3B, Gemma-2-2B, and Qwen-2.5-3B [...].

As shown in this image (https://rocm.blogs.amd.com/_images/scaling_perf_instruct.png) this model outperforms current other "fully open" models, coming next to open weight only models.

A step further, thank you AMD.

PS : not doing AMD propaganda but thanks them to help and contribute to the Open Source World.

Are VPN good for privacy today, should we used them to protect our privacy?

Not free, none have all advantages and wouldn't let my ISP only know my traffic so these times I'm really overwhelmed by all of this

Used Tor for a bit but it's not practically useful, slow (okay but not the main problem) and blocked by a lot of websites..

Maybe a chain of VPN could be good? I really don't know, can you help me?

Basically I don't want to have no protection but don't think VPNs are really the solution...

PS: maybe a rented machine with self hosted like VPN could be good?

I've an UPS but it's not working fine. Disassembled it a bit and tested components that I could without unsoldering, everything seems good. Then the problem is :

• Normally I should be able to connect the batteries and the UPS would just be in "sleep" mode, the screen would be fully light up but the UPS should be off

• The problem here is that firstly when I plug batteries the fan turns on, it should not and only turned on when on batteries but when the UPS is on

• The second problem is that the screen doesn't work as intended. This is a screen that has prewritten zone that just have to be lighted up (don't know the name of this kind of screens, the type like in digital clock), here only the backlight is lighted up (normally all the possible drawing are lighted up too), but quickly it begins to drop in lightness to turn black at the end (the fan continues running)

Check the batteries they are 2 x 12V at 12.6V here

Thanks for your answer

EDIT : on the photo the two blue and brown cable at right are the power plant electricity going to the UPS

Is matrix good to use, seen a lot of drama around it. For example hackliberty.org left it because of lacking of security and moderation, do you still recommended it?

I have an UPS with two 12v 7ah lead batteries. If I want to change the batteries I would typically go with lead batteries but here's my question, can I use some portable mobile power banks to use it?

Because I have a 20000mah "INUI" lithium power bank that is rated for 12v at 1.5A, is it a good practice to buy several of these (since they are about 20 bucks) disassemble them and use them as ups batteries?

EDIT : clarifications

I've got a used riello ups recently and it was not working since the beginning. The UPS was switching to batteries most of the time, but sometimes it just don't switch to batteries and makes a continuous beep (riello manual tells that it's a UPS fault anything except an overload).

I left it 2 weeks without using it. But know it won't start at all. Don't have the materials to test components for now but what are your ideas? (Even when plugged in the wall it wouldn't start)

Maybe batteries or faulty ups

Thx

Since the recent Proton events I need to change providers and I found RiseUP.

I would like to know how good is this service and if I should consider it.

Moreover as I know that it is no open to sign up how to get a RiseUP account? THX for all

Hey I need your help.

Recently I bought a Riello NPW 2000 that output a "pseudo-sinusoidal" wave when running on battery the fact is that I read on the web that modern servers could have problems with it.
Mostly right, as I found that my server (poweredge t430) is not running good with it. When unplugging the power to test the UPS sometimes it make the server just power off and reboot (as said in the bios, turn on when power goes on again) or it put the ups in safety mode (continuous beep).
Tried disabling the PFC in IDRAC settings, as far I haven't noticed power off issues but only safety mode issues with the UPS... (So in fact the server power off, but will never go on battery)

In both cases the server is running fine on battery the issues are just happening when switching.

If anyone has an idea.. Thank you

After research I found that the server never turns off when disabling PFC but will eventually make the UPS goes into fault, I fought it was the fault of the PC that was putting the UPS in protection mode, but it was not the case as I tried to power a TV and it did the same thing.... So I'm good to buy another one...

EDIT : some clarifications & partly resolving the issues
