Description

Hello,
I'm running Rudder 6.0.2 on a CentOS8 server and I'm using the centreon plugin.
First, I encountered the following error when trying to apply a Centreon template :

E| compliant DeploiementGlobalR Monitoring template Global_R Host follows Global_R monitoring template was correct
error: Command related to promiser 'echo | cat /var/rudder/tmp/rudder_monitoring.csv.sign - /var/rudder/tmp/rudder_monitoring.csv | /opt/rudder/bin/curl' returned code defined as promise failed 22
error: Method 'sharedfile_to_node' failed in some repairs
E| repaired Common Monitoring Share Rudder monitoring information with the server was repaired
error: Method 'monitoring_hook_post' failed in some repairs

Then thanks to your help I got to patch this error by doing the following actions :
I applied the patch showed on https://github.com/Normation/rudder-techniques/pull/1578/files/7a5675ac060c97fd9f548a8f4aea74363104443b on the file /var/rudder/configuration-repository/techniques/system/server-roles/1.0/relayd.conf.tpl, then run cd /var/rudder/configuration-repository, git add techniques/system/server-roles/1.0/relayd.conf.tpl && git commit -m "Fix 16549", and rudder server reload-techniques.

The issue is still present and i got the following error on my relayd service:

#11

Updated by Alexis Mousset about 4 years ago

Finally this required a lot of changes.

The problem were that there was some confusion between sent file hash and public key hash, and that consequently the key-hash from the nodeslist file was ignored. Support for forwarding to parent policy server was also missing.

General changes

Added a proper representation of the key hash in nodes list (to parse the algorithm and the hash value separately). This is the most impacting change as it is shared with the reporting code, but it's very small.

For shared-folder API

Refactored hashing code to use an Hash struct containing the algorithm and the hash value. This improves the consistency with shared-files.

For shared-files API:

Replaced the shared-files test data with smaller files (it was an image which is was hard to compare).
Added a simplified version of rudder-sign to the repo to allow easily adding other test cases (it also has more parameters to allow using custom keys, and does not support 1.0 format which is not usable with shared-files)
The shared-files implementation is now now split between a file describing the base data structures (Metadata and SharedFile) in src/data/shared_file.rs and the implementation the the api in src/api/shared_files.rs.
Added the support to forward calls to parent policy server (it was previously missing)
Added 3 tests cases for shared-files PUT API. It was the only call missing tests.
Added more validation of the API parameters (check that things supposed to be hexadecimal really are, check the node id and file id only use alphanumeric chars, check that the public key is parseable by openssl)
