Have you tried typing the whole IPv6 address instead?

Sanmilie · Answer 2 · 2016-07-28T00:05:38.000Z

Same Issue .... say connecting but nothing.

Xinayder · Answer 3 · 2016-07-28T00:06:23.000Z

Is the server set to bind to all IPs (::)?

Sanmilie · Answer 4 · 2016-07-28T00:06:54.000Z

try ipv6.google.com as adress .. it say not DNS Host not resolve.

Sanmilie · Answer 5 · 2016-07-28T00:07:10.000Z

Yes ... i connect server with Telnet client.

Xinayder · Answer 6 · 2016-07-28T00:07:48.000Z

Could you upload your KSP.log please?
EDIT: it's located at your KSP install directory

Xinayder · Answer 7 · 2016-07-28T00:16:56.000Z

Why are you using a custom compiled version of DMP? Also, the log doesn't contain the part where you try to connect to the server.
EDIT: if you're trying to connect to ipv6.google.com it's obvious that it won't work...

Sanmilie · Answer 8 · 2016-07-28T00:17:42.000Z

Nop release version. 0.2.3.1

Sanmilie · Answer 9 · 2016-07-28T00:19:36.000Z

same issue in 0.2.3.0 with KSPV1.1.2

oldmud0 · Answer 10 · 2016-07-28T00:23:09.000Z

I don't think your network infrastructure supports full IPv6 or DNSv6.

Sanmilie · Answer 11 · 2016-07-28T00:26:20.000Z

All my network is ipv6 ..
my server is located at this ipv6 address
2620:ac:4000::39 : 6703
i can connect server with Telnet with this address
i can connect ipv6.google.com with my browser

Sanmilie · Answer 12 · 2016-07-28T00:27:58.000Z

i have ARIN entry...
I have all ipv6 block 2620:ac:4000::/48

Xinayder · Answer 13 · 2016-07-28T00:30:21.000Z

If you're saying that you can connect to your server with this address, what's the output? A bunch of random characters?

Sanmilie · Answer 16 · 2016-07-28T00:33:42.000Z

this is the Telnet side

StollD · Answer 17 · 2016-07-28T00:37:05.000Z

Seems like your DMP Client sends invalid messages (heck, it reports itself as a custom build). Redownload the client from here and try it again?

Xinayder · Answer 18 · 2016-07-28T00:38:46.000Z

Have you tried connecting to your local IPv6 address instead of your public one?

Sanmilie · Answer 19 · 2016-07-28T00:40:54.000Z

I am:

sure that everyone understood that it works with telnet
unsure whether your telnet connection is able to get to a state that triggers the error mentioned above.

Sanmilie · Answer 23 · 2016-07-28T00:45:18.000Z

no problem with ipv4

Xinayder · Answer 24 · 2016-07-28T00:45:33.000Z

Can you upload the logs again? The previous one did not contain the line with the error trying to connect to your server.

Xinayder · Answer 25 · 2016-07-28T00:49:17.000Z

Can you please click connect and don't press disconnect until it gives an error, and upload the log again?

Sanmilie · Answer 26 · 2016-07-28T00:49:55.000Z

It never give error .. wait indefinitly

Xinayder · Answer 27 · 2016-07-28T00:50:40.000Z

Just wait, it will throw an error eventually.

Xinayder · Answer 30 · 2016-07-28T00:59:50.000Z

Have you tried what @ThomasKerman suggested, that was downloading the 0.2.3.1 release version from godarklight.info.tm/dmp?

EDIT: just a note here, you say that it can't resolve your IPv6 but it can resolve your AAAA record. In case you don't know, the AAAA record is a DNS record for IPv6 addresses.

Sanmilie · Answer 31 · 2016-07-28T01:01:53.000Z

ok i Retry immediatly with this version

Xinayder · Answer 34 · 2016-07-28T01:11:21.000Z

I just issued a DNS lookup for your address and it says there was an error looking it up. If you have just added that record, wait a few hours for the change to propagate.

in ipv4 it's work
-snip-

but not in ipv6

Xinayder · Answer 40 · 2016-07-28T01:40:55.000Z

It's something wrong with your install then. The error is no host found. I'm afraid we can't help more.

Sanmilie · Answer 41 · 2016-07-28T01:50:31.000Z

IPv6 is not ready, code review is need for client connetion.

Sanmilie · Answer 42 · 2016-07-28T01:53:05.000Z

i found this on codesource ....
DNS resolver in .net not resolve actualy IPv6 address
Client Application

Again, an IPv6 client application is very similar to an IPv4 application.

Xinayder · Answer 43 · 2016-07-28T01:58:33.000Z

You're wrong, IPv6 is supported by DMP, and we are not responsible for a faulty setup you may have. I just tried a sample project that uses the same methods as DMP uses to lookup host names, and could confirm that if you have a problem in your v6 setup (in mine I don't have v6 on the router, so I can only use v4), it returns "no such host is known".

However, I'm not so sure about the method working flawlessly with v6 in .NET 3.5, which may be the case, and we can't help because Unity won't update their Mono version, leaving us stuck with .NET 3.5.

Sanmilie · Answer 44 · 2016-07-28T01:59:51.000Z

Solution : refactor code with socket.. tcpclient not work in ipv6

Sanmilie · Answer 45 · 2016-07-28T02:00:41.000Z

my setup is good .. framwork have some limitation Telnet is build in C not in c#

Xinayder · Answer 46 · 2016-07-28T02:05:31.000Z

Can you try running this ipv6 tester? It'll just try to call .GetHostEntry for ipv6.google.com and share a screenshot with the result?

Sanmilie · Answer 47 · 2016-07-28T02:21:14.000Z

Sanmilie commented 8 years ago

Xinayder · Answer 48 · 2016-07-28T02:25:12.000Z

Right, so your setup is working, sorry. What is wrong is .NET 3.5 then,
which unfortunately we can't do anything about it. Use IPv4 for now.

Sanmilie · Answer 49 · 2016-07-30T04:48:16.000Z

Usage of winsock2 api directly can make connection working in ipv6
i have try this and it's work well...

-snip-

Xinayder · Answer 50 · 2016-07-30T12:46:10.000Z

Can you please post any code you have to Pastebin or similar?

And we are not going to use an external library to fix Unity's problem. Winsock2 is Windows only and if we used it, DMP would become Windows only, because it would depend on a Windows only library. And we are also not using any library for networking, because the Client is using .NET 3.5 and we can't upgrade because Unity is stuck in this version.
