ipv6 servers "Incorrect parameter"

[The_Great_Beast]

my server is reader.ipv6.xsnews.nl or 2001:67c:174:101::1337
entering it in sab > config > servers it will say
"Incorrect parameter
Server address "2001:67c:174:101::1337:119" is not valid. "

although i can ping it fine

What happens when you fill out:

reader.ipv6.xsnews.nl
newszilla6.xs4all.nl
newszilla.xs4all.nl

What happens when you fill out:

reader.ipv6.xsnews.nl
newszilla6.xs4all.nl
newszilla.xs4all.nl

same as above except for newszilla.xs4all.nl it works

My guess it that something is wrong with IPv6 resolving from within python. (Python seems to have it's own name resolving setup, which can be different from the OS name resolving setup).

Do you have python installed? Can you run "python.exe" from the commandline?

it was not installed. I have it installed now to C:\Python33 and have python.exe

Python 3.3 ... ouch. That's not used by SABnzbd. Let's try anyway:

Start python. Then in python, type:

Code: Select all

import socket
socket.getaddrinfo('www.google.com', None)
socket.getaddrinfo('ipv6.google.com', None)

and post the full output here. See mine below.

So IPv6 name resolving does work in Python. Not what I expected.

Can you find and open sabnzbd.ini, and in there find the line "ipv6_servers =". What's the value filled out?

[The_Great_Beast]

ipv6_servers = 1

[sander]

ipv6_servers = 1

That's good.

I had at a look at the SABnzbd code (check_server() and GetServerParms()), but I can't reproduce the *correct* working so far...

[sander]

OK: with newszilla6.xs4all.nl correctly resolving and ipv6_servers = 1, I can only reproduce the "Server address ... is not valid." with "_EXTERNAL_IPV6 : False"

And that's set / defined as:

Code: Select all

_EXTERNAL_IPV6 = test_ipv6()

Can you copy-paste the code below into a file testing-ipv6.py, and then let python run it? Can you post the output here?

Code: Select all

import socket

def test_ipv6():
    """ Check if external IPv6 addresses are reachable """
    # Use google.com to test IPv6 access
    try:
        info = socket.getaddrinfo('www.google.com', 80, socket.AF_INET6, socket.SOCK_STREAM,
                                  socket.IPPROTO_IP, socket.AI_CANONNAME)
    except:
        return False

    try:
        af, socktype, proto, canonname, sa = info[0]
        sock = socket.socket(af, socktype, proto)
        sock.settimeout(6)
        sock.connect(sa[0:2])
        sock.close()
        return True
    except:
        return False

print "hello!"
print test_ipv6()
print "bye..."

[sander]

Ah ... the difference between python2 and python3. Change the last three lines to:

print("hello!")
print(test_ipv6())
print("bye...")

To be sure: the file is here: http://www.appelboor.com/dump/testing-ipv6.py . Download it, and run it with python.

Stop SABnzbd, in sabnzbd.ini, can you change ipv6_servers to 2? Then start SABnzbd again and try again.
