autobahn-testsuite support for IPv6

[Pioter44]

Hi,

I'm testing Websocket client and server using 'autobahn-testsuite':

• I've tested Websocket client and server with 'autobahn-testsuite' for IPv4 and everything is working

When I want to test Websocket client with 'autobahn-testsuite' for IPv6 then the Websocket client cannot connect with 'autobahn-testsuite' fuzzing server.

• Is any one faced similar issue?
• Does 'autobahn-testsuite' support IPv6?
• is my fuzzingserver.json file for IPv6 correct?
  My IP settings was:
  user@user-VirtualBox:~$ ifconfig
  enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
  inet 192.18.32.6 netmask 255.255.255.0 broadcast 192.18.32.255
  inet6 fd53:7cb8:383:4::11c prefixlen 64 scopeid 0x0
  ether 02:84:cf:3b:be:00 txqueuelen 1000 (Ethernet)

I did some investigation and it seems that 'autobahn-testsuite' fuzzing server is not working for IPv6:
a) Checking if Autobahn-testsuite is working for "localhost" IP settings in fuzzingserver.json file
I. fuzzingserver.json file
{
"url": "ws://localhost:7681",
"options": {"failByDrop": false},
"outdir": "./reports/clients",
"webport": 0,

"cases": ["1.1.1", "1.1.2", "1.1.3", "1.1.4", "1.1.5", "1.1.6", "1.1.7", "1.1.8", "1.2.1", "1.2.2", "1.2.3", "1.2.4", "1.2.5", "1.2.6", "1.2.7", "1.2.8", "2.1"],
"exclude-cases": [],
"exclude-agent-cases": {}
}

I'm not against IPv6 support. But I also don't see any meaning in testing against it if the test over IPv4 already was a success, it's not like anything should behave different. You can easily test the IPv6 connectivity without using Autobahn, e.g. connect to your server with the browser and if that works then connect to it with your client.
