NSCA-ng Release History

Changes in Release 1.6 (2019-03-19)

  • Work around TLSv1.3 PSK bug in (at least) OpenSSL 1.1.1b.
  • Fix static linking against recent OpenSSL versions.
  • Update our copy of libev from version 4.22 to version 4.25. The new release provides a few platform compatibilty fixes and small enhancements.
  • Apply a few minor improvements.

Changes in Release 1.5 (2016-11-15)

  • Include an experimental NSCA-ng client module for Perl.
  • Link against libsystemd instead of libsystemd-daemon when using systemd version 210 or newer, where the latter library has been merged into the former.
  • Include the systemd.service(5) and systemd.socket(5) files with the release tarball.
  • Update our copy of libev from version 4.15 to version 4.22. The new release provides a number of bug fixes and small enhancements.

Changes in Release 1.4 (2014-10-14)

  • Fix NSCA-ng's systemd support: Actually send the keep-alive packets expected by the watchdog.
  • Include an experimental NSCA-ng client module for Python.

Changes in Release 1.3 (2014-07-15)

  • Make the server play nicely with systemd by providing a systemd.service(5) file and adding optional support for socket activation as well as other systemd features, such as watchdog supervision. When compiled with systemd support, the server enables these features automatically if it was socket activated.
  • Fix an issue that prevented compilation on (at least) Solaris and FreeBSD and caused a fatal startup error on (at least) NetBSD and OpenBSD.
  • Make sure our copy of FreeBSD's pidfile(3) code isn't used if the system provides it. The Autoconf test got this wrong in certain cases.
  • Don't buffer log output written to the standard error output.
  • Accept CRLF-terminated client configuration files.
  • Apply a few minor fixes.

Changes in Release 1.2 (2013-11-06)

  • Let nsca-ng.cfg(5)'s include directive and nsca-ng(8)'s -c flag accept directory path names. If a directory is specified, read the server configuration from all *.cfg and *.conf files in the specified directory and all subdirectories.
  • Let the client's -d and -e flags accept C-style escape sequences, so that e.g. -e '\n' can be specified. Octal and hexadecimal numbers are also accepted.
  • Allow for specifying authorization settings outside of the authorize sections in nsca-ng.cfg(5) files. They will then serve as a fallback for authorize sections that don't define these settings.
  • Fix a race condition in the case where the command file is recreated after the NSCA-ng server had opened it.
  • Fix a crash of the client on 32-bit platforms that use 64-bit timestamps.
  • Don't use half-broken POSIX AIO implementations such as the one provided by Debian GNU/kFreeBSD 7.
  • Apply test suite fixes for GNU Hurd.
  • Update our copy of libev from version 4.11 to version 4.15. The new release provides a number of bug fixes and minor enhancements.
  • Apply some minor cleanups.

Changes in Release 1.1 (2013-04-12)

  • Add chroot(2) support to the server.
  • Let the server accept hosts patterns in authorize sections. They're syntactic sugar for allowing host checks to be submitted (analogous to the services patterns for service check submissions).
  • Let the client ignore empty input lines. This fixes some corner cases where NSCA-ng's client didn't accept the same input as the client provided with the original NSCA package.
  • Add the -e client option, which allows for specifying a delimiter to use instead of the ASCII ETB character for separating check results.
  • Let the invoke_check script (provided in the contrib directory of the source tarball) survive plugin return codes other than zero. This should make the script slightly more useful :-)
  • Apply a few minor improvements.

Changes in Release 1.0 (2013-03-06)

  • Actually use the POSIX AIO API if it's provided by the target system. The corresponding Autoconf test was broken since version 0.2.
  • When opening the command file, check whether it's a named pipe. If it's not, log a warning message and retry opening it later on.
  • Use the PSK-AES256-CBC-SHA cipher suite (instead of PSK-RC4-SHA) by default.
  • Apply various minor fixes and improvements.

Changes in Release 0.3 (2013-02-25)

  • First public release.
  • Fix the server's -s and -S options. They were effectively ignored.
  • Mention the session ID in all log messages related to the TLS communication in order to ease debugging.
  • Apply a few minor cleanups.

Changes in Release 0.2 (2013-02-19, Unpublished)

  • Accept non-numeric service check result status when matching against service patterns.
  • Don't accept spurious service check results. This could have happened when service patterns without host name part were specified.
  • Mention the session ID when refusing data.
  • Fix the client's -s option. It was effectively ignored.
  • Don't link the client against the libraries used only by the server.
  • Apply various minor cleanups.

Changes in Release 0.1 (2013-02-08, Unpublished)

  • Initial release.
