Dargslan Toolkit: 15 Free Python Tools for Linux Sysadmins (2026)

Managing Linux servers requires a diverse set of tools — from checking system resources and parsing logs to scanning networks and auditing security configurations. While powerful tools like Nagios, Zabbix, and Datadog exist, they require complex setup, agents, and often expensive licenses.

dargslan-toolkit takes a different approach. It bundles 15 lightweight, dependency-free Python tools that you can install with a single command and use immediately. No agents, no configuration files, no external services — just practical CLI tools and Python APIs for everyday sysadmin tasks.

Install Everything with One Command

pip install dargslan-toolkit

This single command installs all 15 tools. Each tool is also available individually if you only need specific functionality. Every tool has zero external dependencies — they use only Python's standard library, making them safe to install on production servers.

The Complete Tool List

1. dargslan-sysinfo — System Information

Get comprehensive system information including CPU architecture, memory usage, disk space, network interfaces, kernel version, and uptime.

dargslan-sysinfo
dargslan-sysinfo cpu
dargslan-sysinfo memory

2. dargslan-log-parser — Log File Analyzer

Parse and analyze syslog, auth.log, nginx, and Apache log files. Filter by severity level, find failed logins, and extract statistics.

dargslan-logparse /var/log/syslog
dargslan-logparse /var/log/auth.log --level error

3. dargslan-net-scanner — Network Scanner

Perform ping sweeps and port scans across your network. Discover live hosts and open services without installing nmap.

dargslan-netscan ping 192.168.1.0/24
dargslan-netscan ports 192.168.1.1 -p 22,80,443

4. dargslan-firewall-audit — Firewall Auditor

Audit iptables and nftables rules. Detect overly permissive configurations, missing default deny policies, and conflicting rules.

5. dargslan-docker-health — Docker Health Checker

Monitor Docker container health status, resource usage, and detect unhealthy or restarting containers.

dargslan-docker-health report
dargslan-docker-health unhealthy

6. dargslan-ssl-checker — SSL Certificate Checker

Check SSL/TLS certificate expiry dates, cipher suites, and protocol versions across multiple domains.

dargslan-ssl google.com github.com
dargslan-ssl myserver.com -p 8443 --json

7. dargslan-disk-cleaner — Disk Usage Analyzer

Analyze disk usage, find large files, scan temp directories, and identify cleanup opportunities.

dargslan-disk report
dargslan-disk large /home -m 50

8. dargslan-process-monitor — Process Monitor

Monitor running processes, detect zombie processes, track top CPU and memory consumers.

dargslan-proc summary
dargslan-proc zombies

9. dargslan-cron-audit — Crontab Auditor

Audit crontab entries for security issues, missing output redirection, and misconfigured schedules.

10. dargslan-backup-monitor — Backup Monitor

Monitor backup freshness, verify file integrity with checksums, and track backup storage usage.

dargslan-backup report /backup
dargslan-backup check /backup --max-age 24

11. dargslan-user-audit — User Account Auditor

Audit user accounts for security issues — sudo access, empty passwords, duplicate UIDs, and home directory permissions.

dargslan-users report
dargslan-users sudo

12. dargslan-service-monitor — Systemd Service Monitor

Monitor systemd services, detect failed units, and verify critical services are running.

dargslan-svc report
dargslan-svc failed

13. dargslan-port-monitor — Open Port Monitor

Monitor listening ports, detect externally exposed services, and find unexpected network listeners.

dargslan-ports report
dargslan-ports exposed

14. dargslan-log-rotate — Log Rotation Analyzer

Audit logrotate configuration, find large unrotated log files, and analyze log directory disk usage.

dargslan-logrot report
dargslan-logrot large -m 100

15. dargslan-security-scan — Security Scanner

Comprehensive security scan: SSH configuration, SUID binaries, kernel parameters, file permissions, and a 0-100 security score.

Python API — Consistent Pattern

Every tool follows the same simple pattern for Python integration:

# Import the main class
from dargslan_sysinfo import SystemInfo
from dargslan_ssl_checker import SSLChecker
from dargslan_security_scan import SecurityScanner

# Create an instance
si = SystemInfo()
checker = SSLChecker()
scanner = SecurityScanner()

# Use print_report() for formatted output
si.print_report()

# Or call specific methods for programmatic access
cpu = si.cpu_info()
score = scanner.score()
cert = checker.get_cert_info("google.com")

JSON Output for Automation

Every tool supports JSON output, making it easy to integrate with monitoring pipelines, CI/CD scripts, or custom dashboards:

# CLI: Add --json flag
dargslan-sysinfo --json
dargslan-secscan json

# Python: Use to_dict() or json methods
import json
from dargslan_security_scan import SecurityScanner

ss = SecurityScanner()
data = ss.to_dict()
print(json.dumps(data, indent=2))

Why Zero Dependencies Matter

Production servers should have minimal attack surface. Every additional package installed is a potential security vulnerability and maintenance burden. The dargslan toolkit uses only Python's standard library:

• socket — Network scanning and SSL checking
• ssl — TLS certificate inspection
• os/pathlib — File system analysis
• subprocess — System command integration
• json — Structured output
• re — Log parsing patterns

No requests, no click, no rich — just the stdlib that ships with every Python installation.
