  • Auto kill memory leaking processes before swap death loop

    Jump

  • Well that's technically correct, but if you're so dependent on disk cache for system performance that you can't live without it then you really need to look at doing an upgrade.

    When a box swap deaths, it usually struggles to actually fill swap enough to have the kernel still OOM kill it at any point. Generally the massive performance impact of swapping just slows the app down to the point of being useless, along with the entire rest of the box. Disk cache should not be a concern during these abnormal events.

  • Just turn off swap? You don't really need it, and the kernel wiil just oom kill without it.

  • Gluetun: The Little VPN Client That Could

    Jump

  • A lot of reasonably competent geeks just never get deep into networking, and VPNs can be overwhelming. It doesn't really help that for a long time it was all IPSec which basically you need to learn voodoo to manage. Thankfully we have much better tools now, but it's still just a tech layer that many people don't touch frequently.

  • [Tailscale] Can't connect VPS to local network?

    Jump

  • The tailscale client should have created an interface, but I've never used it on a box also running wg. You don't have a tailscale specific interface in ip addr show at all? That's.... odd.

    Do you have a device at /dev/net/tun?

  • How do I do this?

    Run ip route show table all

    I would expect to see a line like:

     
        
192.168.178.0/24 dev tailscale0 table 52

    Out of curiosity on a remote node do tcpdump -i tailscale0 -n icmp and then do a ping from the other side, does tcpdump see the icmp packets come in?

  • Relay "ams" means you're using tailscales DERP node in amsterdam, this is expected if you don't have direct connectivity through your firewall. Since you opened the ports that's unusual and worth looking into, but I'd worry about that after you get basic connectivity.

    So to confirm your behavior, you can tailscale ping each other fine and tailscale ping to the internal network. You cannot however ping from the OS to the remote internal network?

    Have you checked your routing tables to make sure the tailscale client added the route properly?

    Also have you checked your firewall rules? If you're using ipfw or something, try just turning off iptables briefly and see if that lets you ping through.

  • Can your nodes ping each other on the tailscale ips? Check tailscale status and make sure the nodes see each other listed there.

    Try tailscale ping 1.2.3.4 with the internal IP addresses and see what message it gives you.

    tailscale debug netmap is useful to make sure your clients are seeing the routes that headscale pushes.

  • That should be all that's required. Are you using ACLs? If so you need to provide access to the subnet router as well as a rule to the IP behind it

  • I'm facing segfaults with waybar and have come up with a ridiculous solution, is there a better way of doing this?

    Jump

  • Yeah you would need to use a ; instead of &&

  • I guess waybar still returns 0 on segfault. Seems weird.

    Can you un-smart a smart tv?

    Jump

  • This doesn't work on the latest firmware FYI.

    I use this to run an instance of Hyperion on the tv to run leds on the back of it, that dynamically change color to match the show. Since it's native on the tv it works in jellyfin or my pc hdmi cable.

    For me running jellyfin in the tv works so well, it's worth giving it network access.

  • What are your thoughts on E-motorbikes using bike lanes?

    Jump

  • If you can't pedal it and it's faster than a bike bring pedaled, it doesn't belong in a bike lane.

  • Do you host anything specific for tracking house plants and gardening?
