This page contains the changelog for version 2.12 of the ByteBlower. How to update your ByteBlower server is explained in following article:

2.12.12 (2021-04-28)

Enhancements

  • Adding new byteblower-support-tool with functionality for ByteBlower 5100 series

Fixes

  • Fix occasional spikes in latency measurements on the ByteBlower 4100.
  • Fix crash that occurred when running a HTTP flow with a maximum segment size of less than 12 bytes.
  • The ByteBlower Configurator could crash when a DNS server was configured on interface level.
  • The ByteBlower Configurator could crash when more trunking interfaces were configured than allowed by the license.

Misc

  • Adding console utilities so users can configure the keymap (5100 series only)
  • Updating kernel from 4.19.0-13 to 4.19.0-16 (5100 series only)

2.12.10 (2021-03-17)

Fixes

  • Fixes occasional crashes of the MeetingPoint related to checking the license. This was caused by a race condition while locking a Wireless Endpoint when the license was queried.

2.12.8 (2021-02-18)

Enhancements

  • Re-introducing the post-update mechanism.
    This provides the ByteBlower support team with the following information: the current license, the port configuration, the software version from which the update was initiated and the software version the ByteBlower server is updated to.
    This information will only be used for support purposes.

Fixes

  • Fixed TCP performance on the ByteBlower 4100 series' trunking interfaces.
  • The ByteBlower traffic generator tried to start before the network interfaces were up, this caused the traffic generator to crash. (5100 series only)
  • Improve accuracy of latency measurements on 5100 series

Misc

  • Updated Linux kernel from 4.19.0-9 to 4.19.0-13

2.12.6 (2021-01-22)

Enhancements

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

Fixes

  • 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)

Wireless Endpoint support

  • Testing was completed for iOS 14 and macOS Big Sur. The ByteBlower MeetingPoint will not mark these Wireless Endpoints as unsupported anymore

2.12.4 (2020-12-07)

Enhancements

  • The ByteBlower 5100 server can now also update from the console
  • The ByteBlower configurator will warn on an invalid port configurations. Such configurations are mostly encountered during installation of the system.
  • The ByteBlower configurator now also checks the port configuration against the Security license on the server. A warning is given in case of a mismatch, the ByteBlower Server software wouldn't run for such configs.

Fixes

  • Fixed an issue where the ByteBlower configurator did not start when using PTP as a time synchronisation source (2100 and 4100 series only)
  • Fixed an issue where the ByteBlower configurator did not start when an invalid ByteBlower port configuration was set.
  • 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)
  • The OS sometimes provisioned the traffic interfaces with an IP address, even when the configuration told not to. This is fixed (5100 only)


2.12.2 (2020-12-01)

Enhancements

  • The ByteBlower License now supports more than 255 ports on a trunking interface
  • Performance improvement on stateful TCP testing when using IPv6 ports.
  • Improved filtering performance for triggers with a BPF filter containing multiple payload content checks.

Fixes

  • An incorrect timezone configuration could crash the ByteBlower configurator
  • On recent ByteBlower 1300 series servers, ARP failed on trunking interfaces


2.12.0 (2020-11-04)

Warning: This release marks the ByteBlower 1200 server as end-of-life.  The last version supporting this server is 2.11.8

Enhancements
