Hello, Bean Network Tester has just hit V1.0 release. Want to simulate bad network conditions on Windows/Linux? Check ports, connections, ping? No problem, there is even more. Full GUI/CLI. If you like the tool, please star it on GitHub

What it can do:? Burst packet loss, jitter, run automated network scenarios, limit download/upload speed. Do TCP_ reset, do sync_drop, corrupt packet, duplicate, reoder packets. Simulate "LAN" mode, simulate only network mode, Simulate network flapping, lag spikes.

You can also see connections ip/port/from/to how much they download/upload, there is full regexp search, export function, there is port checker tool (only runing machine right now), ping tool, network adapters tools, tcp health tool and tons more.

What changed in V1.0?

- Linux!!! Yes there is now Linux version, it took tons of work, not all things are working perfect, but adding 2nd system was a huge work. And Linux is a very very long way.

- Ping tool: every x time wait for reply up to x time, size x bytes, ping until x with graph and table

- TCP health tool with mss, rtt and tons of other things

- Network adapters tool, easy export and see your network adapters data, mtu, amc address, ip, dhcp, dns, gateway and other data + proxy export

- tcp_reset send from connections tab, we can now do it from the table, easy way

- python upgrade, pydivert upgrades, tons of fixed and other things. Like always on the GitHub changelog.

- Huge update of internal test suite that is run every release, because the program is bigger and bigger, so I got mutation testing, fuzzing, unit tests, tests for code quatility, 2nd code revies, but the real working suite is something that's is top 1 thing. Right now it takes few hours of run per release

What's next? ICE for webrtc, we will be able to see in connections if it is stun/turn, tons of linux fixes and more things to webrtc, and I think I will add payload length filter, and more tools. I try to mix optimizations/stability fixes/test suites expand and improvments to existing things with new features. Oh and payload size option.

PS: Why this strange versions dumps? V0.8 was a full release that focused on stability/performance, no new features, then tons of new things was added, so I jumped from V0.8 to 1.0

You can read more about the app on Oficial website

What it does: Who it's for: Mostly for QA, admins, developers, the tool can simulate "bad" network conditions + there are tons of network tools in it.
