# chroot_manager
|
||
|
||
**chroot_manager** is a fully featured tool for managing chroot environments on Debian‐based systems. It provides a simple command-line interface for creating, connecting to, disconnecting from, and monitoring a chroot jail. The tool supports daemon mode—using `strace`—to log all system calls made within the chroot environment, along with installation and uninstallation support for easy deployment.
|
||
|
||
## Features
|
||
|
||
- **Create** a minimal Debian chroot jail using `debootstrap`.
|
||
- **Connect** to the chroot, automatically mounting necessary filesystems (e.g., `/dev`, `/proc`, `/sys`, `/tmp`).
|
||
- **Daemon mode:** With the `--daemon` flag, run the chroot session under `strace` so that all system calls (and those of forked child processes) are logged to separate files.
|
||
- **Disconnect** from the chroot and unmount all bind mounts.
|
||
- **Status** command to display the current mount status for the chroot jail.
|
||
- **Verbose/debug mode** for detailed logging.
|
||
- **Install/Uninstall:** Easily install the tool (and its man page and bash completions) to system directories.
|
||
- **Extensible:** Designed to be further enhanced with configuration file support, advanced logging, and additional completions.
|
||
|
||
## Requirements
|
||
|
||
- A Debian-based system.
|
||
- Root privileges are required for creating, connecting, disconnecting, and installing/uninstalling the tool.
|
||
- Required commands: `debootstrap`, `chroot`, `mount`, `xhost`, `xauth`, `sudo`, and `strace`.
|
||
|
||
## Installation
|
||
|
||
To install **chroot_manager** system-wide, run:
|
||
|
||
```bash
|
||
sudo ./chroot_manager.sh install [--verbose]
|
||
```
|
||
|
||
This command will:
|
||
- Copy the script to `/usr/local/bin/chroot_manager` and set the executable permission.
|
||
- Install the man page (if `chroot_manager.1` exists in the current directory) to `/usr/local/share/man/man1` and compress it.
|
||
- Install the bash completion file (if `chroot_manager.bash_completion` exists) to `/etc/bash_completion.d/chroot_manager`.
|
||
|
||
## Uninstallation
|
||
|
||
To remove **chroot_manager** and its associated files, run:
|
||
|
||
```bash
|
||
sudo ./chroot_manager.sh uninstall [--verbose]
|
||
```
|
||
|
||
This command removes:
|
||
- The binary from `/usr/local/bin/chroot_manager`.
|
||
- The man page from `/usr/local/share/man/man1/chroot_manager.1.gz`.
|
||
- The bash completion file from `/etc/bash_completion.d/chroot_manager`.
|
||
|
||
## Usage
|
||
|
||
**Basic Syntax:**
|
||
|
||
```bash
|
||
sudo chroot_manager [--verbose] [--daemon] <command>
|
||
```
|
||
|
||
**Commands:**
|
||
|
||
- **create**
|
||
Create the chroot jail using debootstrap.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager create
|
||
```
|
||
|
||
- **connect**
|
||
Mount necessary filesystems, set up X access, and enter the chroot environment.
|
||
With `--daemon`, the session is traced via `strace`, and system calls are logged to files in the daemon log directory (default: `$(pwd)/chroot_daemon_logs`).
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager --daemon connect
|
||
```
|
||
|
||
- **disconnect**
|
||
Unmount the bind mounts from the chroot and revoke X server permissions.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager disconnect
|
||
```
|
||
|
||
- **status**
|
||
Display the current mount status for the chroot jail.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager status
|
||
```
|
||
|
||
- **help**
|
||
Display a detailed help message with usage and command descriptions.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager help
|
||
```
|
||
|
||
- **install**
|
||
Install the tool to `/usr/local/bin` along with its man page and bash completion.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager install
|
||
```
|
||
|
||
- **uninstall**
|
||
Remove the installed tool and its associated files.
|
||
Example:
|
||
```bash
|
||
sudo chroot_manager uninstall
|
||
```
|
||
|
||
## Configuration
|
||
|
||
By default, **chroot_manager** assumes:
|
||
- The chroot jail is located at `/var/chroot`.
|
||
- The Debian mirror used is `http://deb.debian.org/debian`.
|
||
- Daemon logs (when in daemon mode) are stored in a directory in the current working directory named `chroot_daemon_logs`.
|
||
|
||
Feel free to modify these defaults directly in the script or extend the tool with configuration file support in future versions.
|
||
|
||
## Bash Completion
|
||
|
||
If installed, bash completions will allow you to auto-complete the available commands and options when using **chroot_manager** in your shell.
