### Adds Static Mapping for WINS from /etc/samba/samba.static file to /tmp/lib/samba/wins.dat file | |||
'''wins.dat Format Explanation''' | ###### There is no need to stop or start the Samba Service because the OpenWRT StartUp Script (rc.d) has a start position of 95 and the Samba4 Service has a start position of 98, so the SMB service isn't even started when this script runs. The samba4 stop and start lines were put in to note this because according to Samba documentation, the samba service must be stopped to modify the wins.dat file with static entries. | ||
# /etc/init.d/samba4 stop | |||
###### The samba directory and wins.dat file do not yet exist when these commands run during the startup process, so create them and make sure the permission are correct (the permissions should be correct, but explicitly make sure with the chmod command). | |||
mkdir /tmp/lib/samba | |||
touch /tmp/lib/samba/wins.dat | |||
chmod 644 /tmp/lib/samba/wins.dat | |||
###### Append Static Mappings (that the Microsoft term) for WINS in the samba.static file into the /tmp/lib/samba/wins.dat file that is dynamically updated by the SAMBA / NMBD Service, and also created if it doesn't already exist. And as noted, wins.dat file will be deleted when the router is restarted). | |||
cat /etc/samba/samba.static >> /tmp/lib/samba/wins.dat | |||
###### /etc/init.d/samba4 start | |||
