  • This week moved all my vps’s to nixos, so am now able to use one flake for my desktop and all my vps’s which significantly lowers down the time I need to manage my vps’s.

    Nowto move my proxmox homelab server ( an old desktop pc I bought recently ) and all my server’s/devices witll be running nixos.

    EDIT: An issue I’m thinking about is getting a “proper” server. Not a server like a server rack server, but a mini pc or something along those sides wbich would be a lot stronger and a lot more power efficient than the current 10+ y/o desktop pc I’m using currently.

    So would like some reccomendations on that front, like what are some good mini pc brands and mini pc’s that I could have raid seted up on for nas or good budget parts and case to make one myself.

  • I’m using the default list alongside Firehol BotScout list and Firehol cybercrime tracker list set to ban.

    Also using the Firehol cruzit.com list set to do captcha, just in case it’s not actually a bot.

    I’m also using the cs-firewall-bouncer and a custom bouncer that’s shown on crowdsecs tutorials to detect privilege escalation for if anybody actually manages to get inside.

    Alongside that I’m using a lot of scenario collection’s for specific software I’m using like nextcloud, grafana, ssh, … which helps a lot with attacks directly done on a service and not just general scraping or both path traversing.

    All free and have been using it for a year, only complaint I have is that I had to make a cronjob to restart the crowdsec service every day because it would stop working after a couple days because of the amount of requests it has to process.

  • Yes, agree that they are situational. In case if my laptop I’m unervolting mycou because if I won’t it will just crash when used at max speed.

    Edit: in case of my brother pc, the temps were just horenderous for the perforformance he was getting. Plus the fans were barelly on even at 85C. Undervolting and making the fan curve more agresive allowed him the get much better temps at same fan speed, and lets him play some games he wasn’t able to before cause of themps. And the fans even at 100% are quieter than my laptops at 50% so he doesn’t mind them at all.

  • I followed a random guide I found on the internet for amd.

    In amd case you can do it from their driver by going to performance tab and choosing tuning.

    There you will find gpu setting, set them to manual and from there you can start changing fan speed and voltage. Voltage you change by 50mv first time and if stable by 25. When you come to a point where your game/program crashes you use the value from before that didn’t crash the game and that’s it.

    As for nvidia I don’t know because I don’t own one and don’t have the money to own one ( they are 1k euro on average here for 4070 and 2.5k for 4090 on average ) only thing I know is that you will need msi afterburner.

Today I undervolted my brother’s amd rx 6950xt by 120mv ( at 125mv a game we tested would crash at 100% usage and max power draw ).

Also made his fan curve more agressive cause by default it never wen’t over 55% fan speed which is just stupid.

This in total lowered his temps across in mist games from average 80C to 55-60C and lowered power draw on average by 20W.

It also allowed him to play supraland at max settings with gpu not going over 70C instead of lowest setting 80C on average.

So yeah, if you never tried or bothered with undervolting try it and post your results. Or if you did it before post your story and results.

So I’m migrating stuff from my old server to a new provider and only thing left is email.

The problem is I used luke smith’s emailwiz script ( the script and setup itself isn’t a problem ) because it uses system users for managing users with dovecot and friends to setup a mail server.

So now I’m looking for a new email server to selfhost (preferably docker/podman) that in the future I can easilly migrate.Would also love if somebody has a reccomendation on how I could backuo and import emails from the old server.

NOTE: I use caddy as webserver, so the server should have a simple way on getting ssl certs, or abikity to easilly make use if caddy one’s.

  • I got tagged in one called “N***er balls”.

    Imagine waking up and seeting that email notification.

    PS: Picture just to confirm:

    NOTE: I have also seen since yesterday that my crowdsec instance has been blocking way more ip’s for bots trying to crawl and shit like that so I think that this all might be a more general uptake in bots and that sites that never really had great protections against it are now taking the fall.

    Just from yesterday to today I got over 100k more blocks.

    Dec 15 14:14:33 arch systemd[1]: Mounting /mnt/nfs...
    

    According to log’s it’s a systemd-networkd-wait-online.service issue, which shouldn’t be an issue because I’m using ethernet and share get’s automaunt request when I login into my user and load my xorg server.

Hello, I have been having issues where when I just boot my system nfs share takes up to a whole minute to mount, this problem doesn’t exist when I manually run command:

sudo mount -t nfs -o vers=4 192.168.0.4:/mnt/nfs /mnt/nfs

It mounts in max 2 seconds, after a fresh boot with fstab entry removed.

The fstab entry look’s like this:

192.168.0.4:/mnt/nfs    /mnt/nfs    nfs4         _netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=10,timeo=14,x-systemd.idle-timeout=1min    0 0

Is there any way to fix this?

I have tried looking into the arch forums related to this issues and tried to do things like change nfs versions, adding _netdev, even backlisting module rpcsec_gss_krb5.
