JANOS 1.9 Release February 3, 2020

Release Notes

We have released JANOS v1.9 which has several changes and bug fixes. Most notably with TCP packet generation. While it is not wrong to send data in multiple TCP packets, many devices incorrectly implement TCP clients and fail when this case arises. This version adjusted the release of socket data to reduce the chances that a message might be split across separate TCP packets. This had been a recent issue with some MODBUS client devices.

  • Added support for Reverse LLMNR allowing network scanners to label IP addresses with hostnames
  • Adjusted the release of socket data to reduce the chances that a message might be split across separate TCP packets
  • Corrected Sockets race condition that caused occasional reception delays and blocking
  • Fixed the incorrect signed display of large input counter values in JRMON and JMP Protocol
  • Adds a BEACON announcement in the event of an IP conflict
  • Improved NONCE management eliminating possible issues in the presence of port scanners
  • Eliminated chance of buffer overrun occurring in FTP transfer
  • Beacon REBOOT now works in all cases
  • Eliminated potential difficulty in obtaining network capture file

JANOS 1.8 Released June 17, 2019

Release Notes

We have released JANOS v1.8 which adds the JMP Protocol. The JANOS Management Protocol (JMP) is essentially the JSON message interface utilized by JANOS Websockets. The JMP Protocol has been exposed on its own TCP/IP port. This encloses the JSON messaging in a JSON array along with the JSON Object length making reception of the messages easy. The JMP Protocol will be used by the QSC Q-SYS JNIOR component.

  • Implements the JANOS Management Protocol JMP
  • Adds "Block" command to JSON interfaces
  • Web Server limits the effects of extremely slow connections.
