Using ipv6 and Pi-Star 4.0.0.RC4?

How can I accommodate ipv6 addressing on Pi-Star? My Router and ISP are configured for ipv4 and ipv6.

It should just work. Have you checked with ifconfig to see if it has a ipv6 address ?

Code: Select all

pi-star@pi-star-rptr(ro):~$ ifconfig

Ok, perhaps. Mine has both address's and uses IPV6 (at least some times).
Maybe its not getting any IPv6 address's in response to DNS queries. So maybe it's more of a DNS issue

I not an expert at all IPv6. Just making observations.

On mine my router is setup for IPv6 passthrough, and my Pi's have both IPv4 and IPv6 addresses, but it doesn't ever seen to use IPv6 when I ping addresses or anything. From what I can see most of the information out there with Pi's and IPv6 is how to disable it not enable it. lol.
Did you try the option to /ping/ telling it to use IPV6 only?

Is that for LAN and WAN or only WAN targets? Does traceroute/tracert get anywhere before failing?

If you can ping LAN targets with IPV6 mode, but not WAN targets, then something in your router or ISP is blocking IPV6.

Interesting... my Pi-Star system -- 3.4.17 -- has separate ping and ping6 commands, AND does not have an IPV6 address on any interface (including loopback), and no address on eth0 since the box is only using WiFi.

My web-server (running Debian Stretch) does have IPV6 addresses, and uses "ping -6" option. IT can reach my desktop machine.

No surprise that it can't reach the pi-star using IPV6 given mine doesn't have IPV6 addresses

Interestingly -- my desktop can not ping the server machine on IPV6, and gets time outs on IPV4. Suspect that's firewall -- the server is pretty much locked down to just HTTP (port 80) and SSH

Pi-Star v3.x has ipv6 disabled by default, v4.x has ipv6 enabled. If you want ipv6 on your v3.x then it's easy to enable it in the last line of /etc/sysctl.conf, just change the one "1" to a zero "0":

Code: Select all

...
# Turn off IPv6
#net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.all.disable_ipv6 = 0

Hello, I apologise in advance if my question is in the wrong place.

I have upgraded and setup V4 RC4 and although DStar works perfectly, when I look at the live log files for DMR it consistently reports "Login to Master has failed - retrying DMR Network" and never connects - if I put the card back in that has V3.4.17 everything works perfectly. I am "assuming" (probably wrongly) that it has something to do with IPV6 which Vodafone, My home broadband ISP, does not yet support. The router (Billion 8800NL R2) does support it but not much use if the ISP doesn't. Is this my problem please or am I looking at completely the wrong place - any help or advice would be appreciated.

Thank you
Mark.

I don't know the direct answer to your question, but have you tried using a different DMR Master? Also, if you're using BrandMeister, another thing that might help is to set up a Hotspot Security password. There are instructions for that on the Pi-Star Wiki: http://wiki.pistar.uk/Pi-Star_Brandmeis ... t_Security

Hello and thank you both very much. As soon as I am back at home I will read the article you sent Toshen and try the security. I haven't changed any settings other than those which you need to configure when the image is first created. I shall report back, thank you. as i say, 3.4.17 works perfect. V4 RC4 runs much warmer than V3 I notice.

Regards,
Mark.

Hello again, just a quick update to say that appears to have done the trick and changing the security V4 connected first time - thank you so much for your help, advice & assistance.

I note V4 runs at a little over 50 degrees and is orange in colour as opposed to around 45 degrees and green in V3.4.17 so I shall keep an eye on that. No doubt the software will receive an update if it is an issue from it's developer in time.

Regards,
Mark.
