<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>> * * * Release notes for Xymon 4.3.24 * * * <<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>> This documents the important changes between Xymon releases, i.e. changes you should be aware of when upgrading. For a full list of changes and enhancements, please see the Changes file. Changes for 4.3.24 ================== Fixes a bug introduced in 4.3.22 where the non-excepted HTTP status codes were always seen as Critical instead of OK/Warning as intended. All users are urged to upgrade. Changes for 4.3.23 ================== Fixes a bug in 4.3.22 where RRD tracking of number of matching processes or ports open on a client was not being performed. Changes for 4.3.22 ================== The default rules for HTTP response codes have been simplified and made more generic: 1xx = Warning (when the final code received) 2xx = OK 3xx = Warning (except 302/303/307 = OK) 4xx = Critical 5xx = Critical The specific changes from previous versions are: - 401 and 403 response codes are now considered Critical (were OK) - 301 Permanent Redirect response code is now considered a Warning (was OK) - "Extended" or new HTTP status codes in the 4xx and 5xx range are now considered Critical (unknown codes were previously a Warning) In the case of 301, 401, and 403 HTTP codes, if you're expecting to receive this HTTP status from a URL query, you should add the code explicitly to the check by using the "httpstatus" syntax (see hosts.cfg(5)). Basic HTTP Authentication is supported for testing logins to a site. *** Special note: Many vendor-supplied default "Welcome" pages on unconfigured apache servers are actually generated by a 403 error handler. Generically testing for these pages will now show a red status instead of a green one. To fix, simply place an index.html page at the root of the site so that 403's are not generated. The 'sslcert' test will now indicate the signature algorithm and cipher that was actually used in the connection, instead of a list of all ciphers. Use --showallciphers to restore the previous behavior. On new installs, the default apache configuration no longer requires a trailing slash when accessing the xymon pages. http://www.example.com/xymon will work. NTPDATEOPTS, FPINGOPTS, and TRACEROUTEOPTS variables are now present in xymonserver.cfg and will override the default options for the associated xymonnet calls. Note: The suggested options to 'traceroute' were never actually used as the default on a standard installation. In a future release, '-n -q 2 -w 2 -m 15' may be used unless overridden or otherwise specified. Darwin clients (Mac OS X) now exclude AFS and read-only volumes (which are usually just mounted disk images) from processing, properly handle volumes with spaces in their names, and correctly process inode details. A chpasswd.sh file is now provided which allows a logged-in user to change their own .htpasswd password (after verification). Because it verifies their existing password first, it requires the '-v' option to htpasswd, which is only available in Apache 2.4.5 or higher. By default, it is installed in the /xymon-seccgi/ directory, but can be moved to the /xymon-cgi/ directory to allow all users to change their password. Basic input validation is provided, but this CGI should be used with caution and only with relatively-trusted user bases. xymongen used to skip over host groups on pages when it calcuated that there were no test results to be displayed in that table. These groups are now displayed, but you can restore the previous behavior by passing it the --no-showemptygroups option.
