Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

Bean Network Tester v0.6.0

👉 Simulate slow, unreliable, or broken network conditions on Windows to test how applications respond.

Bean Network Tester is a free and open-source network testing and emulation tool for Windows designed for software testers, developers, QA professionals, and power users. It deliberately introduces poor network conditions such as latency, jitter, packet loss, bandwidth restrictions, connection resets, outages, and other problems so you can see how an application behaves when its connection is less than perfect. Traffic can be targeted by process name, PID, IP address, port, or address family, allowing one application to be tested without necessarily disrupting the rest of the computer.

The program uses the WinDivert driver to intercept and manipulate network traffic and provides both a graphical interface and a command-line interface suitable for scripts and CI/CD testing. Along with network impairment, it includes live statistics, throughput monitoring, a searchable connections table, event logging, configurable profiles and presets, reproducible seeded tests, CSV exports, and reproduction reports. Bean Network Tester is portable, requires administrator privileges to manipulate network traffic, and contains no telemetry or update-checking network client. It is released under the GNU General Public License v3.0.




Features:
• Add fixed or random network latency and jitter
• Introduce latency spikes to simulate unstable connections and packet reordering
• Drop packets randomly or in bursts to reproduce real-world wireless network failures
• Corrupt or duplicate packets
• Limit download and upload bandwidth in KB/s
• Simulate network buffering and queuing delays
• Tear down existing TCP connections using TCP resets
• Prevent new connections from being established
• Simulate a completely dead network link
• Flap the connection on and off to reproduce intermittent outages
• Simulate MTU black holes and NAT-style idle timeouts
• Block selected IP addresses or ports with the built-in firewall controls
• LAN mode allows local network traffic while blocking Internet access
• Internet-only mode blocks local network traffic while allowing Internet access
• Target traffic by process name, PID, IP address, port, IPv4, or IPv6
• Supports lists, ranges, exclusions, wildcards, regular expressions, and CIDR notation in traffic filters
• Includes ready-made connection presets such as 3G, weak Wi-Fi, cafe Wi-Fi, satellite, in-flight Wi-Fi, train/metro, DSL, 56K modem and others
• Create and save custom network profiles
• Run timed scenarios that automatically change network conditions during a test
• Schedule repeating bandwidth changes without creating a complete scenario
• Use a reproducible random seed to repeat the same packet loss and jitter behavior
• Live Statistics view displays packet counts, loss, corruption, reordered packets, throughput and other activity
• Connections view shows the IP addresses and ports the computer is communicating with and how much traffic is transferred
• Search, sort, freeze, and inspect connection information
• Export session statistics and connection information to CSV files
• Generate reproduction reports containing settings, counters and the command line needed to repeat a test
• Event log records starts, stops, setting changes, scenarios, bug markers and resets
• Full command-line mode for scripting and CI/CD automation
• CLI supports exit codes and machine-readable JSON output
• Simulation mode can validate a command without modifying actual network traffic
• Portable ZIP version requires no installation
• No account, telemetry or external network communication

Supported operating systems:
• Windows 10 64-bit, Windows 11 64-bit

Supported languages:
English, Polish, Simplified Chinese

Changes:
v0.6.0 09-04-26
Added burst packet loss with the new "Losses in a row (burst)" setting and --loss-burst command-line option.
Wireless presets now use burst loss to more closely reproduce real wireless connection failures.
Added a Loss runs statistic to the Statistics tab, CSV statistics and reproduction reports.
Added IPv4-only and IPv6-only targeting in both the graphical interface and command line.
Added a complete Simplified Chinese interface translation alongside English and Polish.
Added a Reordered packet statistic and packets_reordered field to statistics CSV files.
Added selectable display units of KB/s, Mbit/s or MB/s for speed statistics.
Improved Control page layout, search behavior and descriptions for latency, packet ordering and burst loss settings.
Expanded documentation to cover additional network impairment and testing features.
Fixed possible saved-file corruption when multiple copies of the program were running.
Made running-session setting changes atomic for more reproducible tests.
Fixed stale process-targeting information after connection-list errors.
Fixed scenarios occasionally applying another step after being stopped.
Improved crash reporting and handling of repeated errors.
Fixed saving errors that could previously close the program.
Connection CSV exports now run without freezing the interface.
Improved connection-table search performance and recovery from refresh failures.
Fixed interface timers remaining active after changing languages.
Prevented repeated interface faults from opening large numbers of error dialogs.
Fixed failed start or stop operations potentially leaving the START button unusable.














Note:
This file has three hits on VirusTotal. We have confirmed these to be false positives. The file is safe.

Note from The Older Geeks:
VirusTotal shows 3 detections out of 65 security vendors, while the remaining 62 report the file as clean. The detections specifically reference WinDivert, a legitimate network packet interception driver used by Bean Network Tester to manipulate traffic for latency, packet loss, throttling, firewall, and other network simulations. Because this type of driver can also be used by malicious software to alter network traffic, some antivirus products classify it as a risk tool, PUA, or rootkit-like component. The small number of detections, combined with their focus on WinDivert, is consistent with the program's intended network-testing functionality rather than, by itself, evidence that Bean Network Tester is malicious.
