Bonjour, j’ai le même problème :  UNKNOWN: Command error: Host key verification failed.

Seulement j’ai suivis les consigne indiquer sur cette page pour l’échange de clé ssh :https://docs.centreon.com/pp/integrations/plugin-packs/procedures/applications-monitoring-centreon-central/#ssh-key-exchange

J’ai également changer l’extra option : --verbose --ssh-username=centreon.

 

Mais mon problème reste le même.

 

Quelqu’un peut m’aider ?

Merci d’avance.

su - centreon-engine
ssh-keygen -t ed25519 -a 100
ssh-copy-id -i ~/.ssh/id_ed25519.pub centreon@localhost

 

j’utilise actuellement un poller qui est lui même sur le même serveur que mon application WEB Centreon

(je n’ai qu’un serveur pour toute ma supervision et mon application web et en générale pour tout si jamais j’ai oublier quelque chose)

et ma ligne EXTRA OPTION a comme valeur : --verbose --ssh-username=centreon

car si j’utilise les valeurs : --verbose --remote --ssh-option='-l=centreon'

J’ai une erreur qui ressemble a cela : Unknown option: remote at /usr/lib/centreon/plugins//centreon_centreon_central.pl line 2248.

t cat -n /usr/lib/centreon/plugins//centreon_centreon_central.pl | grep 2248
   = 2248                    warn "Unknown option: $option" if ($warn_message == 1); ]

 

je n’arrive pas a cerner ce qui ne fonctionne pas, sachant que j’ai suivis la procédure a la lettre :(

Encore merci a vous.

En cherchant je suis tombé sur ton topic , j’ai donc suivi la doc idoine .
