2.12.6 (2021-01-22)


  • Adding more feedback to the user during initialization and validation operations. These can take a while.


  • Fixed a bug that caused ICMP ping replies to sometimes be sent to the wrong destination. (Fixed for both IPv4 and IPv6.)
  • The ByteBlower configurator did not save the fixed network configuration¬† (1x00, 2x00, 3x00 and 4x00 series
  • The ByteBlower configurator did not save the DNS configuration when configured statically (1x00, 2x00, 3x00, 4x00 series)
  • The ByteBlower configurator did not apply the new DNS configuration when it was altered (1x00, 2x00, 3x00, 4x00 series)
  • When the server could not determine whether an update is available, the system was not able to generate the message of the day. This caused a crash in the ByteBlower configurator. (5100 series only)

2.12.4 (2020-12-07)


  • The ByteBlower 5100 server can now also update from the console

  • The login banner (console/ssh) was never updated with the recent information (5100 only)
  • The login banner (console/ssh) was always showing that the updates couldn't be retrieved (5100 only)
