# Comprehensive Linux Troubleshooting Tools Guide
This guide provides an overview of key packages and their included tools for effective troubleshooting in Linux environments, specifically tailored for RHEL and Debian-based distributions.
## Tools Commonly Included in Most Linux Distributions
- **GNU Coreutils**: A collection of basic file, shell, and text manipulation utilities. Key tools include:
- `df`: Reports file system disk space usage.
- `du`: Estimates file space usage.
- **Util-linux**: A suite of essential utilities for system administration. Key tools include:
- `dmesg`: Examines or controls the kernel ring buffer.
- **IPUtils**: Provides tools for network diagnostics. Key tools include:
- `ping`: Checks connectivity with hosts.
- `traceroute`: Traces the route taken by packets to reach a network host.
## RHEL (Red Hat Enterprise Linux) and Derivatives
- **Procps-ng**: Offers utilities that provide information about processes. Key tools include:
- `top`: Displays real-time system summary and task list.
- `vmstat`: Reports virtual memory statistics.
- **Net-tools**: A collection of programs for controlling the network subsystem of the Linux kernel. Includes:
- `netstat`: Shows network connections, routing tables, and interface statistics.
- **IPRoute**: Modern replacement for net-tools. Key utility:
- `ss`: Investigates sockets.
- **Sysstat**: Contains utilities to monitor system performance and usage. Notable tools:
- `iostat`: Monitors system I/O device loading.
- `sar`: Collects and reports system activity information.
- **EPEL Repository** (for tools not included by default):
- `htop`: An interactive process viewer, enhanced version of `top`.
## Debian and Derivatives
- **Procps**: Similar to procps-ng in RHEL, it provides process monitoring utilities. Key tools include:
- `top`: For real-time process monitoring.
- `vmstat`: For reporting virtual memory statistics.
- **Net-tools**: As with RHEL, includes essential networking tools like `netstat`.
- **IPRoute2**: A collection of utilities for controlling and monitoring various aspects of networking in the Linux kernel, featuring:
- `ss`: A utility for inspecting sockets.
- **Sysstat**: Similar to its usage in RHEL, includes tools like `iostat` and `sar` for performance monitoring.
## Conclusion
This guide emphasizes the importance of familiarizing oneself with the tools included in standard Linux packages. Whether you are operating in a RHEL or Debian-based environment, understanding the capabilities of these tools and their respective packages is crucial for effective troubleshooting and system monitoring.
