  • Nine Raspberry Pis power this entire office

    You can set up a Pi-Hole (DNS sinkhole) and Pi-VPN (Wireguard installer and CLI-frontend for small deployments) very quickly. And you can do it on any debian VM or computer, not just Pi.

    Once you have the base OS ready to go, it will take you less than 30 minutes if you know how to muck with your DHCP/firewall settings in your router.



  • PiVPN - Router/WIFI stopped workign after Pi was unplugged
    My PiVPN setup for openvpn as per https://pivpn.io/ wouldn't pull the router over, but I agree that if your setup is doing dhcp or dns that could make it look like the router is failing.

    reddit.com/r/pivpn | 2021-10-07
    pivpn update is supposed to take care of it, but old enough install can be buggy so probably just remove and reinstall if it's possible to re-deploy the configs.
  • I am tired of people in this sub treating VPN as "the golden hammer"
    Thus ss you'd have to be complete in that sense as otherwise you'd have nothing to connect to. Also to prevent the whole world to connect to it and start brute forcing it, you should have things like fail2ban, connection whitelists or whatever setup to reduce the attack vector somewhat. So for more most who are unexperienced, a vpn is easier to achieve... especially with a solution like https://pivpn.io to have a wireguard or openvpn setup using server and client certs on a raspberry pi for example.

    Try pivpn, easy to setup a Wireguard or OpenVPN server.

    reddit.com/r/VPS | 2021-09-25
    This is the best option for you. You can actually setup wireguard faily easily with pivpn although you may need to tinker around for a bit in order to expose your local network on the VPN's subnet.

    https://pivpn.io/ Really simple to setup. Also, I found this instructions: https://www.wundertech.net/setup-wireguard-on-a-raspberry-pi-vpn-setup-tutorial/

  • How many of you use SSH to manage your server?
    I'm using Slack Nebula as a simple VPN mechanism. Nebula is how I network all of my computers together. It works 90% of the time (until you have other VPNs on, like work VPNs, then it can get confused, but hey).
  • I am tired of people in this sub treating VPN as "the golden hammer"
    You should add Nebula to the list, essentially zerotier but open source.
  • Smb over wireguard/tailscale/openvpn slow try nebula
    reddit.com/r/sysadmin | 2021-10-02
    I currently have reasons for using smb over long distances which introduces latency and was struggling to get speeds faster than dialup. Every forum and reddit posts suggest MTU and optimizing things.. I couldn't get it work no matter what I did. So I setup my own Nebula lighthouse node mesh network (a lot like tailscaile but self hosted) and tried smb over that network instead. I was instantly able to saturate my bandwidth. Hope this helps

    news.ycombinator.com | 2021-10-01
    Have you looked into https://github.com/slackhq/nebula? It uses X509 cert for auth.

    Although for my home lab, using X509 is more of a minus than a plus due to complexity involved.

  • Headscale: Open-source implementation of the Tailscale control server
    news.ycombinator.com | 2021-09-17
    Another similar project to Tailscale, for those in the market:


    Crazy simple, fully open source, trivial to self-host. Maybe not as featureful as Tailscale, but imo that can be a feature unto itself.

  • Tailscale free for open source projects
    news.ycombinator.com | 2021-09-17
    As other have suggested, Nebula (https://github.com/slackhq/nebula) is pretty elegant. It has groups-based access built in which is extremely convenient.

    You can bolt-on SSO fairly easily - just create a certificate signing service. I created https://github.com/unreality/nebula-mesh-admin in a weekend, so its fairly easy to add a SSO flow in.
