• New I2C/SPI Tap plugin

  Support for the upcoming I2C/SPI Tap is already here!

• New Replay Log plugin

  Replays TX/RX records from a log file with respect to timestamps, thus preserving time intervals between packets.

• HTTPS for communications with ioninja.com

  All the communications with our server (usage reports, crash reports, and evaluation requests) are now performed using encrypted HTTPS connections. See the updated PRIVACY statement for more details.

• Support for async/await in the Jancy language.

  The convenient and (rightfully) popular asynchronous programming paradigm is now fully supported in Jancy (the scripting language of IO Ninja). As usual, we went an extra mile — and made all async functions schedulable.

• Support for BREAK condition in the Serial and Serial Monitor plugins.

  Now the Serial plugin allows you to manually trigger BREAK condition on a serial line while the Serial Monitor plugin will show you when other processes are doing so.

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

2019-02-01

IO Ninja 3.10.2 is out!

Service Release

Download IO Ninja 3.10.2

• Fixes persistency for sessions and logs with layers

  This release resolves the issue of not being able to reopen sessions or logs — when saved with an attached layer.

• New option for auto-showing the terminal console on connect

  For many sessions, once a connection is established, you want to switch into the terminal mode — now it's possible to do automatically.

• New option for reopening a serial port on disconnect

  If this option is ON and the currently opened serial port disappears (e.g., a device with a USB-to-Serial peripheral controller reboots), the Serial session will keep attempting to reopen the port (with a configurable delay between attempts).

• New option for maintaining TCP connections

  If this option is ON and a remote node drops the connection, the TCP session will keep attempting to reconnect (with a configurable delay between attempts).

• Updates for IO Ninja IDE

  IO Ninja IDE is now compatible with the new plugin design introduced in 3.10.0.

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

2018-12-14

IO Ninja 3.10.1 is out!

Service Release

Download IO Ninja 3.10.1

Notable updates in v3.10.1 and v3.10.0:

• Fixes for plugins broken in v3.10.0

  Along with many updates, v3.10.0 introduced a few regressions affecting the following plugins: TCP Flow Monitor, Named Pipe Monitor, Mailslot Monitor, Regex Colorizer. These regressions are fixed in v3.10.1 and all plugins are functional again.

• Raspberry Pi support

  Many users contacted us asking for a Raspberry Pi build of IO Ninja. Your wish is our command — now you can run both IO Ninja and the Device Monitor service on your Raspberry Pi!

  

• New plugin: Serial Monitor over SSH

  With this plugin, it's possible to monitor serial ports on remote machines. For example, run IO Ninja on your MacBook Pro and see what a script on your Raspberry Pi is sending over /dev/ttyS0 — in real time!

  

• The half-duplex mode in Modbus Analyzer

  Often Modbus over RS-422 or RS-485 operates in half-duplex mode — both parties transmit data over the same pair of lines. This effectively makes data bytes of requests and replies indistinguishable from one another. However, it's not a problem anymore — the Modbus Analyzer plugin now has a special decoding mode to combat this.

• New 64-bit log record code architecture and log representer plugins

  Log record codes in IO Ninja v3.10.0 and above are globally-unique 64-bit numbers (previously, log record codes were 32-bit and unique only within a specific plugin). This change has many long-run consequences such as eliminating log record code collisions once and for all, ability to easily and safely share log representers between plugins, dramatically decreased compilation time when opening logs (only a representer has to be compiled, not the whole plugin), etc.

• New implementation of Jancy reactors

  Reactors in the Jancy language are workhorses of spreadsheet-like reactive programming. You write a block of expressions (or formulas), and the runtime automatically re-runs those formulas whenever any referenced value changes — just like in Excel, only it's your program! The new design alleviates most of the previous limitations, and now you can write practically any formulas — intuitively and without any performance penalty. This is perfect for UI programming!

• Crash reports on Linux and Mac OS X

  Now it's easy for you to help us find and fix problems — but only if you choose to, of course! IO Ninja uses libunwind to collect stack backtraces on application crashes; these backtraces together with some basic system information can be automatically submitted to our web server over an encrypted channel. You can skip sending, inspect and delete crash manifests, or completely disable crash report submission.

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

IO Ninja 3.9.2 is out!

Download IO Ninja 3.9.2

• Critical fixes in Ninja Scroll and Jancy

  A few critical bugs were discovered during fuzz-testing. This release should eliminate many opportunistic crashes in both ioninja and ioninja-server.

• Delayed cache update feature in Ninja Scroll

  Now plugins can choose thresholds for lowering cache update rate so that frequent UI updates don't slow the data acquisition down. This feature is critical for high-throughput logging, such as in the upcoming I2C/SPI sniffer which is capable of capturing SPI data at 50MHz.

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

2018-09-05

IO Ninja 3.9.1 is out!

Download IO Ninja 3.9.1

• Script transmit pane

  Convenient scriptable transmission is finally here! Now you can write a loop which would keep re-transmitting packets with some delay. Or programmatically set-up a complex packet with a checksum or signature. Or generate packets containing random bytes. Or iterate through a predefined list of targets and send a packet to each one. Or other non-trivial transmission scenarios — you've got the idea.

• Redesign of packet templates

  Packet templates always was a cool and unique feature of IO Ninja — but the one which only a few knew about and used... This release brings a few significant improvements to the packet template feature which make it easier to find and much more convenient and intuitive. The idea is to copy-paste C-language definitions of packet structs and then edit packet fields using the property grid.

• Support for Modbus ASCII & Modbus TCP

  Previously, IO Ninja could only handle Modbus RTU. Now, the improved Modbus Analyzer plugin also supports Modbus ASCII and Modbus TCP. It also provides much more polished output (dense vs verbose view, colorized sections of Modbus frames, etc).

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

2017-08-08

IO Ninja 3.9.0 is out!

Download IO Ninja 3.9.0

• Major redesign of the Ninja Scroll logging engine

  Now it's much more responsive under high-load and with huge (multi-gigabyte) logs due to the fully parallel processing of indexing, representing, converting, searching, etc.

• New USB Control Endpoint plugin

  Allows low-level communication with USB control endpoint #0 — great for testing and debugging the USB devices under development.

• New TX Modifier plugin

  Appends prefix and/or suffix, re-transmits with the specified interval, inserts inter-character delays.

• New TX/RX Filter plugin

  Allows to filter out (exclude) TX or RX streams out of the log — extremely helpful when local echo clutters the view.

• Custom serial baud rates

  Your wish is our command! As per your requests, we added editable combo-box properties — now you can specify arbitrary baud-rates in all serial-based plugins.

• Hung server process detection and termination

  Now potential problems with the ioninja-server process should not affect the main GUI process — just terminate a hung session and start a new one.

• Unicode support for TEMP path on Windows

  Previously, having non-ASCII characters in TEMP (e.g. when your username includes non-English letters) would result in the error: A device attached to the system is not functioning. Not anymore!

• Lots of BUGFIXes and other improvements — as usual!

  For a full list of changes see changelog.txt (also included in all installation packages).

IO Ninja 3.8.6 is out!

Download IO Ninja 3.8.6

• New EZ-Tap Pro plugin

  EZ-Tap Pro and Versa-Tap are popular serial tap cables from Stratus Engineering Inc. With the addition of this new plugin, IO Ninja can be used as a powerful and feature-rich alternative client for working with these great sniffer devices!

• Colors in the "Information" pane

  Checking serial line states is easier now as there is a visual hint — "on" is red, "off" is gray.

• COM-port device descriptions in drop-downs

  With the new property gui.ComboBox.m_isDualItemText it is now possible to have an editable combo box, but have descriptive texts in the drop-down. Fits perfectly for showing COM-port device descriptions in serial port drop-downs — while still being able to type a device name directly!

• Plugin scripts and issue tracker are on GitHub now!

  The sources for all the official plugins have been put to a public GitHub repo. Now, whenever you find a bug in a script you can fix it yourself and send us a pull-request. The same goes for new features — and maybe even new plugins!

IO Ninja 3.8.5 is out!

This release introduces the following new features:

• Dramatic (~20x) performance boost in find-in-log and save-log-as-text

  Thanks to the new server-side range processors feature in the Ninja Scroll logging engine, searching through multi-gigabyte logs (collected, for example, over a weekend) is no longer a problem. The same goes for saving log as text — the speed of these operations increased by an order of magnitude compared to versions prior to 3.8.5!

• New Informational pane with throughput calculator, checksum calculator, session stats, etc

  IO Ninja features a pane on the right of the main window with all kinds of useful information: throughput, total TX and RX byte counters, session time, checksums of the selected range (CRC-16, CRC-32, IPv4, etc). Of course, you can always hide it — if it's too much information for you.

• New Tibbo Modbus Gateway Monitor plugin

  IO Ninja provides a native plugin for monitoring a line of Modbus Gateway devices from Tibbo — conveniently relay, decode and analyze Modbus traffic flowing through our Modbus gateways!

• Support for ARP/InARP protocols in the Network Sniffer plugin

  Of course, this had to be done long time ago... but it was waiting for some real-world incentive — which presented itself during a recent debugging session over one tricky ARP-cache related issue. And voila, support for ARP/inverse ARP is finally here!

• Lots of BUGFIXes and other improvements -- as usual!

IO Ninja 3.8.4 is out!

This release introduces the following new features:

• Serial Tap Cable monitoring plugin

  IO Ninja can now be used with serial tap cables such as EZ-Tap from Stratus Engineering Inc.

• Streaming mode in Tibbo Device Monitor for improved performance & scalability

  With streaming mode it's possible to simultaneously pass multiple buffers to the kernel device filter driver, thus increasing overall throughput. Low-level details such as parallelism, buffer sizes, pending queue limits, etc — are all configurable!

• All the Tibbo Device Monitor-based plugins have been re-written using the generic io.DeviceMonitor class

  Check the sources of Serial Monitor or Named Pipe Monitor to see how to process and log serial-specific or NPFS-specific IOCTLs — then extend those or roll out your own new device monitoring plugins for Windows and Linux!

• Detection and workarounds for buggy USB-to-serial drivers

  Certain serial drivers just... do not play nice — some can't handle simultaneous read IRPs, some don't process COMMTIMEOUTS properly, etc. IO Ninja falls back to conservative (although slightly less performant) settings when it detects an unreliable driver.

• Lots of BUGFIXes and other improvements -- as usual!

IO Ninja 3.8.0 is out!

This major release introduces the following new features:

• New terminal emulator console

  The terminal emulator console in IO Ninja can now be free-floating or tabbed (next to the log). New settings were added for making the console auto-sized or fixed-sized, for controlling various terminal compatibility options, etc.

• Regular expression-based log colorizer

  The new Regex Colorizer layer plugin allows you to highlight your log according to regular expressions of your choice. Write a regex, select text attributes to apply when its found in data stream(s) and — voila! The pattern will be found and highlighted even if it spans across inter-packet boundaries! You may add as many highlighting rules as you want without performance drop!

• Improved layer and custom plugin support

  This release adds layer persistency when saving log files or sessions with layers. Another important addition is the add-on plugin manager. Now IO Ninja can be configured to use custom-written add-on plugins without modifying the configuration files!

• Key authorization support in the SSH client plugin

  Finally, IO Ninja can be used for connecting to SSH servers which require key authorization. The key file must be PEM-encoded (the most widely used key file format). It goes without saying, that the password authorization is also available like before.

• Lots of BUGFIXes and other improvements -- as usual!

  For a full list of changes see changelog.txt which is included in all installation packages.

Service release IO Ninja 3.7.8 + tdevmon 3.2.3

This release contains two important BUGFIXes in tdevmon:

• read-beyond-end-of-buffer in tdevmon for Windows

  This bug could cause occasional BSODs when monitoring named pipes with particularly long names (a big thanks to Gil Cohen from Comsec Group for the crash dumps).

• MSI upgrade/repair/remove issues in tdevmon for Windows

  If tdevmon was used for monitoring any devices, both upgrade and repair via the MSI installer would return errors; reboot was never really requested (even when needed). Refer to this KB article for more details.

Besides these bugfixes, the new release also features:

• Clickable fields in decoded ModBus RTU messages in the ModBus RTU Analyzer;
• Extra keyboard compatibility options in the terminal settings;
• Support for the alternative line-drawing character set in the terminal widget;
• More minor BUGFIXes and improvements!

IO Ninja 3.7.7 is out!

What's new?

• Serial monitor for Linux

  And yes, this is a real serial monitor — not one of those pipe-redirect/termios-proxy type of applications confusingly calling themselves "serial monitors" (the ones you normally find on the Internet when searching for a "Linux serial monitor").

• Improved Linux inter-distro compatibility

  We distribute IO Ninja in form of pre-compiled binaries on Linux, and it caused us problems in the past — due to the vast number of Linux distros. We have significantly reduced the dependency set and the chances of IO Ninja running on your Linux are much higher now.

• Dual WHDC SHA-256 EV & SHA-1 driver signatures for Windows 10 v1607+ compatibility

  Starting with Windows 10 v1607 it is necessary to submit drivers to Microsoft WHDC (Windows Hardware Developer Center) for verification and signing. We comply with these strict requirements — our drivers carry both WHDC-supplied SHA-256 EV (extended validation) signatures for Windows 10 and legacy SHA-1 signatures for Windows 7 and Windows XP.

• Support for monitoring of remote named pipe/mailslot connections on Windows

  Previously IO Ninja only allowed monitoring the local NPFS/MSFS filesystems on Windows. It was a major source of confusion — why not all the named pipe communications are displayed in my log? Well, now you will see remote connections as well!

• Dynamic structures in the Jancy language

  Everyone who has ever programmed low-level network IO knows how often network protocols use variable-sized packet headers, where the size of a field depends on some other "length" field. From now on Jancy allows describing such headers in the most natural way — using variable-lengthed arrays, thus yielding dynamically laid-out structs.

• Lots and lots of BUGFIXes!

  These include two rare, but critical BSOD conditions in the device monitoring service on Windows.
