I found a documentation that it’s interesting.  You can find it here

Server availableServer disponible

After my freebox upgrade to the new version revolution, my network has been unavailable and my domain too ! With the new version of firmware, the system seems to be accessible now. Sorry for the inconvenience.

Note for the future, do not change hardware with a new version as soon as it is available. What ? It’s not possible. Why ???
It’s impossible to wait 🙂Après la mise à jour de ma freebox vers la freebox révolution, mon domaine n’était plus joignable. Avec la nouvelle version du firmware le problème semble résolu (avec une réorganisation de mes routeurs).Désolé pour les problèmes.

Note pour plus tard, ne pas changer vers une nouvelle version dès qu’elle est disponible. QUOI ??? C’est pas possible ???
Pourqoui??? Parce que c’est impossible d’attendre. 🙂

I have encountered an issue. I have tried to remove one package without success.
Another package was using it.

pkgrm SUNWnfssu

The following package is currently installed:
SUNWnfssu Network File System (NFS) server support (Usr)
(i386) 11.10.0,REV=2005.01.21.16.34

Do you want to remove this package? [y,n,?,q] y

## Removing installed package instance

This package contains scripts which will be executed with super-user

Do you want to continue with the removal of this package [y,n,?,q] y

So it tried to remove the SUNWnfssr package without success. the SUNWnfssu was using it too. Damned.

To force the removal you can use


pkgrm -a none SUNWnfssr

J’ai rencontré un problème sous Solaris. J’ai essayé d’enlever un paquet sans succès. Un autre paquet l’utilisait.

Que cela tienne, je décide d’enlever le paquet l’utilisant, mais ce dernier utilisait aussi le précédent paquet.
Damned. Un deadlock sur les dépendances.

Pour pouvoir forcer la désinstallation, vous pouvez utiliser:


pkgrm -a none SUNWnfssr
