Checkmk Werk 14607: cmk_update_agent: Fix fetching root certificates from server

by Andreas Umbreit

ID: 14607 Title: cmk_update_agent: Fix fetching root certificates from server Component: agents Level: 1 Class: Bug fix Version: 2.2.0i1 This Werk is only incompatible for users that actually tried to use the broken <i>trust-cert</i> option of the agent updater. This is a regression since Checkmk 2.0. When invoking cmk-update-agent with <tt>--trust-cert</tt> or <tt>-t</tt> option, you can trust and save the root certificate needed for the HTTPS connection to the Checkmk server directly from the server's certificate chain (if it's stored there). Previously, the fetched certificate got saved in a wrong format (python <tt>bytes</tt> instead of <tt>str</tt>), leading to a crash when the agent updater tries to import it in subsequent calls. You can fix your broken installations by editing the host-local file <tt>/etc/cmk-update-agent.state</tt> or <tt>%ProgramData%\checkmk\agent\config\cmk-update-agent.state</tt>, respectively: Please remove all occurring <tt>b</tt> prefixes from the <tt>local_certificates</tt> entry. Alternatively, you can update the agent once manually by calling the agent updater with <tt>--insecure</tt> option. This will skip the certificate handling entirely; the updated agent updater can then fix the malformed values by itself.

Checkmk Werk 14712: <tt>check_http</tt>: Consolidate host and proxy settings

by Joerg Herbel

ID: 14712 Title: <tt>check_http</tt>: Consolidate host and proxy settings Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The active check <tt>check_http</tt>, which monitores HTTP services, is configurable via the ruleset <i>Check HTTP service</i>. Before this werk, users could configure three host addresses there: LI: A hostname or IP address LI: A virtual host LI: A proxy server However, <tt>check_http</tt> has only two arguments to specify host addresses: <tt>-I</tt> for the actual address to be contacted and <tt>-H</tt> for the virtual host. Hence, specifying an address, a virtual host and a proxy server in the ruleset did not make sense. In fact, before this werk, if all three of them were specified, the virtual host was simply ignored. As of this werk, users can configure two options instead of three: the address to contact (either directly or a proxy server) and a virtual host. In case users select to configure a proxy server, they can optionally provide the corresponding port and credentials, as before. Furthermore, using a proxy most likely requires the HTTP method <tt>CONNECT</tt>. This method is now used automatically if a proxy is configured, unless a different method is explicitly selected. Previously, this was only the case for the certificate checking mode, but not for the URL checking mode.

by Lukas Lengler

ID: 14149 Title: Crash: Clustered services using predefined cluster modes Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Using Clustered services with predefined cluster mode certain services would crash if no summary (therefore only notice) was available for a node result.
