As part of my testing, I do a backup of my live system, then try to restore to a standby system in case of a need for disaster recovery.   I made a post-upgrade backup of my 7.0 live system, and installed 7.0 from the ISO on a standby system.

However, I'm getting an error when it gets to the Samba restore part.   In the log it appears that there is an extra / being put into the path, but I can't figure out where that is coming from.  Here is the output of the zentyal.log file for the error:

Installation and Upgrades / Possible to configure IPv6?
« on: March 05, 2017, 05:17:20 am »
Hello all,

I have a 4.2 installation, and was wondering if it is possible to use stubs to configure IPv6.  I realize that none of the GUI tools will work with IPv6, and everything will have to be done command-line.

I seem to have it working from the Zentyal instance itself out to the Internet.  But so far no luck with machines on the LAN segment behind the Zentyal box. 

I've used the interfaces.mas file in the stub directory to manually set the IPv6 addresses for eth0 and eth1.  I was delegated a /56 address, so I used one /64 subnet for the outside eth0 interface and another /64 for the inside.  I configured radvd to send info to the internal network on eth1.   I set sysctl.conf to forward ipv6, and there is a default route going out eth0.   I can successfully run the tests at test-ipv6.com from the browser of the Zentyal machine.  But on any LAN machine if I run a traceroute it ends at the link local address of eth1.

I've check ip6tables, and they are empty at the moment.  I'm sure I'm probably missing something simple and obvious, but I can't for the life of me figure out what it is.  Has anyone else had any luck getting native IPv6 (not tunneling) work when using a Zentyal box for internal machines?
