По умолчанию Problem with 5030/74

Нello All,

Can one of you Russian speaking guys please help this guy? The problem appears to be that his firewall blocks the binkp port on IPv6.

% nc -6 cats-home.net 24554

with

# tcpdump -nlvv host 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a

in parallel, results in:

20:45:51.832045 IP6 (hlim 64, next-header: TCP (6), length: 32) 2a01:4f8:221:3dc1:900d:f001:dead:f001.37076 > 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a.24554: S, cksum 0x61f7 (correct), 101011674:101011674(0) win 14400 <mss 1440,nop,nop,sackOK,nop,wscale 7>

So, most likely the binkd there simply listens only at IPv4.

Maybe. But in that case I would expect a time-out rather than a connection refused.

So maybe you can contact him to help solve the problem?

The Ipv6 list now counts 58 nodes. It would be nice if we could make it 60 by the end of the year.


Cheers, Michiel

Answer with TН_RST flag set is a normal way for the OS kernel to reject connection to a port nothing listens on.

Unlikely.

I'll write in R50.SYSOP.DRUNK with this idea.
Possibly, there would be 64...

So your theory is that his binkd listens on IPv4 only.

MvdV>> So maybe you can contact him to help solve the problem?

AV> Unlikely.

Why? Нe advertises IPv6 connectivity. Won't you help him to get his function to perform as advertised?

У меня сложилось такое же впечатление.

19 Dec 13:13:58 [2823] session closed, quitting...

Если кто подскажет, куда копать -- было б здорово. С маху не увидел настроек IPv6 для входящих соединений в шаблоне конфига BinkP.
IPv6 завёлся относительно недавно, пока не всё на домашнем сервере настроено.

С наилучшими пожеланиями, Michael.
