Water is one of the major requirements for human survival. During the past decade, water needs have risen exponentially to an unprecedented scale in India. The rapid urban development, increasing human population, climate change and wasteful usage have led to severe water shortages. The solution lies largely in areas of effective mechanisms for conservation, distribution, efficient use and management of this resource. Ensuring access to safe and clean water is another issue that requires attention. In this paper, we present an IPv6 network connected design for real-time water flow metering and quality monitoring system. Design of v6 engine for sale in india Flow Meter System for India.Our prototype implementation uses the emerging HTTP-compatible CoAP based monitoring and control approach for seamless web integration, thus supporting internet based data collection. The system addresses new challenges in the water sector - ease of billing, fair billing and the need for a study of supply versus consumption of water in order to create awareness to curb water wastage and encourage its conservation.

MFG: ABB:AX25-30-10-80 2From within the host i have a global ipv6 address which is working fine but i can’t get access to ipv6 hosts from within any docker container.
These are my current settings to my docker deamon:v6 engine for sale in india
Adding --ip-forward=false or the google ipv6 DNS servers doesn’t help either
Only if I add --net=host it works so I think I’m missing a fundamental network configuration part.iconfig from within an ubuntu:latest docker container shows this:

You might need to pass in a smaller subset of your /64 in to the --fixed-cidr option, set sysctl net.ipv6.conf.default.forwarding=1, sysctl net.ipv6.conf.default.all=1, and run an ndb proxy announcing your smaller subnet.
Alternatively, you could give docker its own /64 subnet (not the same subnet that your eth0 is in), and set up routes for that subnet to your docker host.
Way more details on getting ipv6 set up can be found here: https://docs.docker.com/engine/userguide/networking/default_network/ipv6/
kannix (Kannix) April 27, 2016, 6:19am #3
I’ve read the docs but for me this part:
With the --fixed-cidr-v6 parameter set Docker will add a new route to the routing table. Further IPv6 routing will be enabled (you may prevent this by starting Docker daemon with --ip-forward=false):

sounds like docker will setup these options for me? and setting them manually doesn’t seem to make a difference
the last part of the first paragraph seems to be an optional info
Often servers or virtual machines get a /64 IPv6 subnet assigned (e.g. 2001:db8:23:42::/64). In this case you can split it up further and provide Docker a /80 subnet while using a separate /80 subnet for other applications on the host

If your Docker host is only part of an IPv6 subnet but has not got an IPv6 subnet assigned you can use NDP proxying to connect your containers via IPv6 to the internet.Design of v6 engine for sale in india Flow Meter System for India.so all in all i think i did everything stated in the docs :sweat:
What happens if you look at your routing table and look at the current value of those sysctl values?
The sysctl settings are active, even after a reboot. My routes are:
@programmerq do you know if there is anything obvious wrong with that routing table? I would guess it could be a problem that there are equal routes for eth0 and docker0?
schinzelh (Schinzelh) May 9, 2016, 1:47pm #7
I ran into a similar problem, maybe it is of help:
My host has a public routable /64 ipv6 subnet assigned. I’ve added
DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4 --fixed-cidr-v6=2607:5300:60:a7bc:2::/80 --ipv6"
to my docker deamon settings to assign a /80 subnet to Docker. The docker container ended up with
eth0
with 2607:5300:60:a7bc:2:242:ac11:3 being pingable from host machine, but the container not being able to reach outside world. I finally gave the NDP proxy you mentioned above a try, and it did the trick for me:
$ sysctl net.ipv6.conf.eth0.proxy_ndp=1
and$ ip -6 neigh add proxy 2607:5300:60:a7bc:2:242:ac11:3 dev eth0
Hope that helps,Holger
kannix (Kannix) May 9, 2016, 5:03pm #8
Thx for the input but a solution where i have to add each ipv6 address by hand is a no go for me :sob:
schinzelh (Schinzelh) May 9, 2016, 7:38pm #9
Fair enough. Maybe using a NDP proxy daemon (ndppd) like mentioned in the documentation could do it as workaround:
Linux have a limited support for proxying Neighbor Solicitation
messages by simply answering to any messages where the target IP
can be found in the host’s neighbor proxy table. To make this work
you need to enable “proxy_ndp”, and then add each single host to the
neighbor proxy table by typing something like:
ip -6 neigh add proxy <ip> dev <if>v6 engine for sale in india
Unfortunately, it doesn’t support listing proxies, and as I said,
only individual IPs are supported. No subnets.
‘ndppd’ solves this by listening for Neighbor Solicitation messages
on an interface, then query the internal interfaces for that target
IP before finally sending a Neighbor Advertisement message.
You can create rules to query one interface for one subnet, andanother interface for another. ‘ndppd’ can even respond directly to
Neighbor Solicitation messages without querying anything, should you need that.Design of v6 engine for sale in india Flow Meter System for India.The primary motivation for IPv6 deployment by service providers and enterprises is the steady exhaustion of the IPv4 address pool.

I have used ndppd for testing, but it is less than ideal in my opinion. I’ve noticed a few seconds delay before newly created containers seem to have good ipv6 connectivity. Design of v6 engine for sale in india Flow Meter System for India.This causes things to fail since not all packets seem to get through. Maybe I simply didn’t have ndppd configured quite right.
The best solution, in my opinion will be to give your docker daemon an entire /64 subnet, and your docker host will act as a router for that. If you can get a /48, that seems to be a good clean solution.
