Le nom d'hôte local change toutes les quelques secondes lorsqu'il n'est PAS connecté à un réseau.

Situation réelle de la question

Lorsque je réveille mon ordinateur portable, mais avant d'être connecté à un réseau, je reçois des messages similaires à ceux qui suivent :

This computer's local hostname
"sojourner-896.local" is already in use on
this network. The name has been changed
to "sojourner-972.local"

Si je ne me connecte pas à un réseau et que je ne clique pas sur le bouton "OK", les noms d'hôtes continuent de s'incrémenter. Si je me connecte à un réseau (avec ou sans fil), les noms cessent de s'incrémenter.

Je réinitialise le nom d'hôte dans le panneau de préférences "Partage" lorsque les noms d'hôtes se situent entre 5 000 et 6 000 (tous les 2 ou 3 jours).

Une idée de la cause de ce problème ?

J'ai consulté les journaux via l'application console et j'ai constaté que les journaux suivants sont générés chaque fois que je suis déconnecté d'un réseau :

J'ai réactivé le réseau à la seconde 10:08:14.

Le processus actuel qui a changé le nom d'hôte est le suivant configd . La page de manuel de configd déclare que

The configd daemon is responsible for many configuration aspects of the
local system. configd maintains data reflecting the desired and current
state of the system, provides notifications to applications when this data
changes, and hosts a number of configuration agents in the form of loadable
bundles.

et

At the present time, the majority of the configuration agents (or bundles)
hosted by configd are used to establish and maintain the network
configuration.

Les pages du manuel énumèrent les fichiers connexes suivants :

 /Library/Preferences/SystemConfiguration/preferences.plist
 /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
 /Library/Preferences/SystemConfiguration/VirtualNetworkInterfaces.plist

Le dossier preferences.plist semble avoir les préférences réseau telles que spécifiées par le panneau de préférences réseau dans les Préférences système. J'ai fait une sauvegarde, je l'ai supprimée, j'ai tué configd et a effectué un redémarrage de bas niveau :

cd /Library/Preferences/SystemConfiguration/
cp preferences.plist ~/Desktop/preferences.plist
sudo rm -f preferences.plist
sudo killall configd
sudo killall configd
sudo reboot

Après le redémarrage du système, le système ne change plus le nom de l'hôte toutes les quelques secondes lorsque PAS connecté à un réseau.

En cherchant un peu, j'ai trouvé un fil de discussion sur SuperUser qui pourrait vous aider.

https://superuser.com/questions/49891/how-can-i-stop-mac-os-x-overriding-my-hostname-when-i-receive-a-dhcp-request-on

C'est très étrange que cela se produise alors que vous n'êtes PAS connecté à un réseau. J'aimerais avoir une meilleure réponse.

Il me semble me souvenir d'une préférence cachée quelque part dans les Préférences Système qui permet au Mac d'obtenir un nom d'hôte dynamique à partir du serveur DHCP, mais je ne parviens pas à la trouver. trouver ce fichu réglage. Donc soit je me souviens mal, soit c'était quelque chose d'une incarnation précédente de Kitty.
