I have a working install of unimus (great platform, BTW) but I am seeing some strange inconsistencies. A number of the devices I need to manage are only manageable via IPv6. I have the "prefer ipv6" option checked, but it does not appear to use v6 but works fine over v4. I can ssh into all of the devices manually from the unimus system over v6. I suspect it's the java version, but I don't know enough to tell.

Code: Select all

Raspbian GNU/Linux 9 (stretch)

Unimus version : 1.7.2. 

java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) Client VM (build 25.171-b11, mixed mode)

Native dual stack
Any insight appreciated.

Hi,

Which of these cases is not working for you?

1) IPv6 address as the device address
Here, Unimus should communicate over IPv6 directly

2) DNS hostname that resolves only to an IPv6 address as the device address
Here again, Unimus should communicate over IPv6 directly

3) DNS hostname that resolves to both IPv4 and IPv6 addresses as the device address
Here, the checkbox "Prefer IPv6..." should control how Unimus connects to the device

I have failure in both #2 and #3. I have verified connnectivity via ssh from the unimus host using v6.

Another data point, I don't see an attempted connection on the remote device over v6 for either case, #2 or #3.

I will test these cases here and update as soon as I have any news.

I apologize for the delay, we have been focusing on a rewrite of the discovery logic for 1.8.0 for the last 2 weeks.

The rewrite is almost finished, I will get to testing IPv6 as soon as we ship a 1.8.0 Beta with the new discovery algorithms :)
