I will use environment variables for the interfaces value in my smb.conf file. The use of environment variables works fine some values, but the interfaces value is not be expanded.

The part of my smb.conf is:

   log file             = %$(SAMBA_CONF_DIR)/log/log.%m
   private dir          = %$(SAMBA_CONF_DIR)/private
   pid directory        = %$(SAMBA_CONF_DIR)/locks
   lock directory       = %$(SAMBA_CONF_DIR)/locks
   smb passwd file      = %$(SAMBA_CONF_DIR)/private/smbpasswd
   bind interfaces only = yes
   interfaces           = %$(SAMBA_VIF)

I got following error message:

sys_gethostbyname: Unknown host. %$(SAMBA_VIF)
can't determine netmask for %$(SAMBA_VIF)
WARNING: no network interfaces found


The SAMBA_VIF variable is set. To a logical hostname for the current host.

Christian.
