# server-scripts
|
|
|
|
Useful scripts for managing servers written in Bash. Supported OS includes only Ubuntu/Debian and Alpine.
|
|
|
|
In the past I was using it more for maintaining my home servers, bare metal with Docker, however when I changed to k3s, I started using it less. Now I'm using this as a collection of useful scripts that I can use when needed. Also `clean.sh` is still useful.
|
|
|
|
### `clean.sh`
|
|
|
|
This script is used to clean some of the files, docker dangling images, and docker stopped/unused containers.
|
|
|
|
### `windows-backup.ps1`
|
|
|
|
This PowerShell script is used to backup files from a Windows machine to a remote Samba server. It uses `7zip` to create the zip file, and then sends over the network using SMB protocol.
|
|
|
|
### `dns-override.sh`
|
|
|
|
Aggressive, best-effort DNS override script for Linux hosts with support for multiple resolver stacks (`systemd-resolved`, `NetworkManager`, `resolvconf/openresolv`, `dhclient`, `systemd-networkd`, and `ifupdown`) plus direct `/etc/resolv.conf` writes.
|
|
|
|
It prompts for:
|
|
- 2 required DNS servers
|
|
- 1 optional third DNS server
|
|
|
|
Validation/features:
|
|
- Accepts IPv4 and IPv6 literals
|
|
- Rejects invalid or duplicate entries
|
|
- Performs reachability checks (warn-only, does not block execution)
|
|
- Can optionally lock `/etc/resolv.conf` with `chattr +i`
|
|
|
|
Run with `curl | bash`:
|
|
|
|
```bash
|
|
curl -sSL https://git.ivanch.me/ivanch/server-scripts/raw/branch/main/dns-override.sh | bash
|
|
```
|
|
|
|
Important notes:
|
|
- Requires interactive TTY input (prompts are read from `/dev/tty`)
|
|
- Requires root privileges (`sudo` is used/re-execed when possible)
|
|
- Script is intentionally aggressive and may restart/reload network services
|
|
- On heavily managed systems (custom agents, immutable images, enterprise policy), behavior is still best-effort
