IO Ninja Programmable Terminal/Sniffer - free download

IO Ninja is an all-in-one scriptable terminal, sniffer and monitor. It's aimed at system administrators, network security experts and developers of communication software. IO Ninja is free for non-commercial usage.



Out-of-the-box IO Ninja provides:

* Serial terminal

* TCP terminal (client/server)

* UDP terminal (client/server; UDP broadcast support)

* SSH terminal

* TCP proxy (man-in-the-middle-style monitoring)

* Windows named pipe terminal (client/server)

* Serial monitor

* Network sniffer

* Windows named pipe monitor



The latest version of IO Ninja has excellent support for binary data -- both editing binary packets before sending as well as displaying both incoming and outgouing (RX/TX) binary data in a communication log:

* Text editor with support for escape sequences (n, xFF, u2661 etc)

* Modern hex editor with support for all UTF encodings

* Template packet editor -- define a packet structure in C-language and then edit the fields with property grid

* Binary data is interleaved with informational textual messages thus providing a clean single-sheet log

* Display binary data as hex-view or plain text, merge incoming packets together, etc

* Multiple modes of binary data copy (copy-as-text, copy-as-hex, copy-as-C-array, save-as-file etc)



IO Ninja features Session Linking which turns it to a universal redirector. Create two sessions (e.g. Serial and TCP), configure them and then link them together. All the data will be passed-through from one end to another and vice versa.



IO Ninja is programmable with Jancy language and it turns IO Ninja into a universal IO debugger. With scripting you can:

* Modify any standard session

* Write custom protocol analyzers and syntax highlighters

* Write testing utilities (e.g. wait for incoming packets, analyze, send something in return)



IO Ninja has an IDE to assist you in exploring and making use of IO Ninja scripting.
