Fixes for FreeNAS

There is an error trying to install Plugins, It mentions Jails but it has NOTHING to do with the jails. 

See the issue here....

https://bugs.freenas.org/issues/4680

On a command line this is the fix.....

• echo '64.62.136.38 cdn.freenas.org' >> /etc/hosts

Once you have upgraded to the latest version you cannot turn CIFS on and off. And consequently not change permissions. 

Fix for CIFS Share

As root and in SSH do the following commands:

• cd /tmp
• fetch https://bugs.freenas.org/attachments/download/768/fixup.sh.txt
• chmod +x fixup.sh.txt
• mv fixup.sh.txt fixup.sh
• ./fixup.sh
