You don't want a duplicated UDP packet to crash your application. Though nowadays it seems everybody have high speed broadband Internet connection, it's still important to face the fact that network transportation isn't always reliable.

Tamper, nudge bits of packet's content.Out of order, re-arrange the order of packets.Duplicate, send cloned packets right after to the original one.Throttle, block traffic for a given time frame, then send them in a single batch.Lag, hold the packets for a short period of time to emulate network lagging.When started clumsy will only capture packets based on the filter, leaving others untouched.Īfter packets are captured, you can choose to enable provided functions to worsen perspective network condition: If you figured out what's going on then go to Download page and give it a try! If not, scroll on:Ĭlumsy will choose which packets to capture by given filter, in which in can specify whether it's inbound or outbound, tcp or udp, socket port or ip, or a logical combination of many of those criterias. Here's a demo of clumsy working on a netcat listening for localhost udp packets, illustrated as animated gif. Interactive controll how bad the network can be, with enough visual feedback to tell you what's going on.Your application keeps running, while clumsy can start and stop anytime.Works even if you're offline (ie, connecting from localhost to localhost).Support not only HTTP, any protocol based on TCP/IP is supported.System wide network capturing means it works on any application.No need for proxy setup or code change in your application.Whether you want to track down weird bugs related to broken network, or evaluate your application on poor connections, clumsy will come in handy: the packets on demand, then send them away. Leveraging the awesome WinDivert library, clumsy stops living network packets and capture them, lag/drop/tamper/. Clumsy makes your network condition on Windows significantly worse, but in a managed and interactive manner.
