NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver ...

this indicates a mismatch between the installed nvidia driver and the current kernel version. the solution involves using dkms (Dynamic Kernel Module Support) to rebuild the nvidia driver against the new kernel.

]]> managing frp with systemd: a best-practice approach https://blog.zayx.me/2024/10/31/managing-frp-with-systemd-a-best-practice-approach/ Thu, 31 Oct 2024 22:15:39 +0800 xxxx https://blog.zayx.me/2024/10/31/managing-frp-with-systemd-a-best-practice-approach/ frp is a fantastic tool for intranet penetration, but managing it effectively can be a challenge. systemd provides a robust and elegant solution for automating frp’s startup and ensuring its resilience. this post will guide you through creating a best-practice systemd unit file for frp, focusing on clarity, efficiency, and robustness.

here’s the optimized unit file:

[Unit]
Description=frp server
Requires=network-online.target
After=network-online.target

[Service]
ExecStart=/usr/bin/frpc -c /path/to/your/frpc.ini
Restart=on-failure

[Install]
WantedBy=multi-user.target

let’s break down the key components:
