[SABnzbd 0.7.9] [Errno 61] Failed to connect [IPV6]

Postby fabtax » January 20th, 2013, 8:33 am

Hello,

I'm having problems with SABnzbd with newszilla6 and weathergirl ipv6 nntp server.
I can't connect to ipv6 nntp server.
I run FreeBSD 9.1.

ping6 worked for both.
ping6 weathergirl-ipv6.tele2.net
PING6(56=40+8+8 bytes) 2a01:e35:2e45:xxx:xxx:xxx:xxx:xxx --> 2a00:801:103:10::35

Logs after trying to load a nzb with newszilla6 enable:

I found posts about special config ipv6-server set to "2", but this workaround didn't work either.

What kind of IPv6 connection do you use? Some IPv6 tunnel providers block News / NNTP traffic. Easy check: a telnet session to port 119, like this:

Code: Select all
[email protected]:~$ telnet newszilla6.xs4all.nl 119
Trying 2001:888:0:18::119...
Connected to newszilla.ipv6.xs4all.nl.
Escape character is '^]'.
201 dreader37.news.xs4all.nl NNRP Service Ready - [email protected] (no posting).

DATE
111 20130120151948

LISTGROUP
481 No group specified

QUIT
205 Transferred 130 bytes in 0 articles, 0 groups.  Disconnecting.
Connection closed by foreign host.

Hello,
That's what i tought...
I already checked via telnet without sucess :|

telnet newszilla6.xs4all.nl 119
Trying 2001:888:0:18::119...

telnet: connect to address 2001:888:0:18::119: Operation timed out

But which provider is your IPv6 provider? Your ISP, or an IPv6 tunnel provider?

I guess you're not using Free.fr, because they provide (almost-)native IPv6 using the great 6RD...

Free.fr is my ISP right now and yes im using 6RD via free.fr :)
ipv6 free nntp were working like a charm few weeks ago.
I don't why it's not working now.
A telnet on news.free.fr (in ipv4) works well.
I tested weathergirl and newszilla6

Oh. Strange. Is your IPv6 working at all? Test with:

Code: Select all
wget -6 http://www.google.com

and visit http://test-ipv6.com/


Another possibility is that newszilla6 is blocking traffic from free.fr ... but I don't think that is something newszilla6's owner xs4all would do ... So this possibility is just theoretical.

ping6 is working for ipv6.google.com but not a wget -6...
I don't understand at all...
i'm checking my packet filter settings but my pseudo device pflog0 don't drop anything of ipv6 stuff...

Try to disable then enable ipv6 support on my provider interface, still the same problem :/

ipv6 conf in rc.conf:
ipv6_prefer="YES"
ifconfig_nfe0_ipv6="inet6 accept_rtadv"

I don't know what pflog0 is ... a Packet Filter log?

Do you have a firewall turned on? If so, turn it off and see what happens.

I you have another system on your LAN, check if IPv6 works on that system. Or live-boot a Linux (Ubuntu?) CD/USB-stick and see if that works.

pflog is a pseudo device that allow it to tcpdump to see what kind of packets are rejected with your packet filter rules.
I checked it and my firewall allow ipv6 traffic well.

I'm gonna try with another system like GNU/Linux to test if it's a FreeBSD problem or not.

Thnaks for your help.

Regards.
