From 2e84dd5c03a9e8b75cd66f5c7a4cacc93ef3fa9c Mon Sep 17 00:00:00 2001 From: umerfarok Date: Sat, 29 Mar 2025 16:34:11 +0500 Subject: [PATCH 1/3] Enhance platform-specific functionality for network monitoring - Refactored launcher.py to include OS-specific imports and logging for Windows, macOS, and Linux. - Added LinuxNetworkMonitor class for Linux-specific network functionalities, including interface management and device control. - Introduced MacOSNetworkMonitor class for macOS-specific network functionalities, including interface management and device control. - Updated monitor.py to utilize platform-specific network monitor classes for better modularity and maintainability. - Improved error handling and logging throughout the codebase for better debugging and user feedback. - Added new dependencies for macOS and Linux in requirements.txt to support platform-specific features. --- networkmonitor/cli.py | 2 +- networkmonitor/dependency_check.py | 234 +++++++++++++- networkmonitor/launcher.py | 109 ++++++- networkmonitor/linux.py | 229 ++++++++++++++ networkmonitor/macos.py | 213 +++++++++++++ networkmonitor/monitor.py | 474 +++++++++-------------------- networkmonitor/npcap_helper.py | 2 +- networkmonitor/splash.py | 2 +- networkmonitor/windows.py | 2 +- requirements.txt | 9 +- 10 files changed, 917 insertions(+), 359 deletions(-) create mode 100644 networkmonitor/linux.py create mode 100644 networkmonitor/macos.py diff --git a/networkmonitor/cli.py b/networkmonitor/cli.py index c449531..802945d 100644 --- a/networkmonitor/cli.py +++ b/networkmonitor/cli.py @@ -39,7 +39,7 @@ def start(host, port, check_only): # Keep the server running controller.wait_for_shutdown() except KeyboardInterrupt: - click.echo("\nShutting down...") + click.echo("\nShutting down...") controller.stop_monitoring() @cli.command() diff --git a/networkmonitor/dependency_check.py b/networkmonitor/dependency_check.py index b746eaa..c5afb95 100644 --- a/networkmonitor/dependency_check.py +++ b/networkmonitor/dependency_check.py @@ -17,9 +17,20 @@ def __init__(self): ("Python Version", self._check_python_version), ] - if platform.system() == "Windows": + # Add OS-specific checks + os_type = platform.system() + if os_type == "Windows": self.checks.append(("Npcap", self._check_npcap)) + elif os_type == "Darwin": # macOS + self.checks.append(("Admin Rights", self._check_admin_macos)) + self.checks.append(("pfctl", self._check_pfctl_macos)) + elif os_type == "Linux": # Linux (Ubuntu) + self.checks.append(("Admin Rights", self._check_admin_linux)) + self.checks.append(("iptables", self._check_iptables)) + self.checks.append(("tc", self._check_tc)) + # Check Python packages for all platforms + self.checks.append(("Python Packages", self._check_python_packages)) def check_all_dependencies(self): """ @@ -70,19 +81,143 @@ def _check_npcap(self): return False, "Npcap is not installed.
