[2.4.0] Checkmk Werk 16617 created: Use session specific key for ValueSpec encryption

by Checkmk werks level 1

[//]: # (werk v2) # Use session specific key for ValueSpec encryption key | value ---------- | --- date | 2024-03-15T15:28:00+00:00 version | 2.4.0b1 class | feature edition | cre component | wato level | 1 compatible | yes When a user edits a configuration e.g. for a special agent with an explicit password the complete configuration is transfered to the user. To not reveal the password in cleartext this field is encrypted. The key for that encryption was previously to this Werk shared amongst all users (a salt was used though). With this Werk every user session has now a secret dedicated to this encryption so the key is rotated often and not shared amongst other users.

[2.1.0] Checkmk Werk 16379 adapted: Allow disabling of bulk walks on inline SNMPv3 hosts

by Checkmk werks level 1

Werk 16379 was adapted. The following is the new Werk, a diff is shown at the end of the message. Title: Allow disabling of bulk walks on inline SNMPv3 hosts Class: fix Compatible: compat Component: checks Date: 1710141228 Edition: cre Level: 1 Version: 2.1.0p42 It was impossible to disable bulkwalks for SNMP version 3 hosts using the inline SNMP backend. It is fixed now in the sense that it works as in the classic backend: In order to disable bulkwalks for SNMP version 3 hosts, you need to make sure they do not match the ruleset "Enable SNMPv2c and bulkwalk for host". A more thorough fix for this bug and the related phrasing in the rulesets is implemented in for Checkmk 2.3, but it was too risky to port into the stable releases. See <a href="https://checkmk.com/werk/16382">Werk #16382</a> for more on that. ------------------------------------<diff>------------------------------------------- Title: Allow disabling of bulk walks on inline SNMPv3 hosts Class: fix Compatible: compat Component: checks Date: 1710141228 Edition: cre Level: 1 - Version: 2.1.0p41 ? ^ + Version: 2.1.0p42 ? ^ It was impossible to disable bulkwalks for SNMP version 3 hosts using the inline SNMP backend.
