Failed to initialize connection to IPv6 server

Post by sander »

SABnzbd says "Failed to initialize" to IPv6-only newsservers:

Code: Select all

sander@flappie:~$ cat ~/.sabnzbd/logs/sabnzbd.log | grep newszilla6 | tail -5

sander@flappie:~$
This seems to happen after my computer has reconnected to the network (with IPv6), and/or has connected to a new network (with IPv6).

A restart of SABnzbd 'solves' the problem.

So: does SABnzbd save the (old?) state of the connections to newsservers ("not working") instead of setting up a fresh connection?

IPv4 and IPv6 are treated exactly the same, unless the Python libraries do otherwise.
Does traffic resume after about 10 minutes?
(This is the lock-down period for unwilling servers.)

I don't think so, but I'll try.

Thanks.

I can't reproduce it; so far SABnzbd behaves well.

See logging. First: network with no IPv6, then network with IPv6, and SAB nicely picks. And "sudo netstat -apon | grep 119 | grep tcp6" shows IPv6 connections.

So ... false alarm from my side ...

Re: Failed to initialize connection to IPv6 server

Post by sander »

Still the same problem: IPv6 is working system wide, but SABnzbd thinks it's not. I think this happens after the network interface has been down or after some IPv4-only was there for some time.
Pausing SABnzbd does not solve it.
Restarting SABnzbd does 'solve' it, so to me it feels some state (of non-working IPv6) is saved by SABnzbd or python

I think I'll put my own connect-to-ipv6-code into downloader.py to verify and show IPv6 is working

Code: Select all

                        try:
                            logging.info("%s@%s: Initiating connection",
                                              nw.thrdnum, server.id)
                            nw.init_connect(self.write_fds)
                        except:
                            logging.error(T('Failed to initialize %s@%s'), nw.thrdnum, server.id)
                            logging.info("Traceback: ", exc_info = True)
                            self.__reset_nw(nw, "failed to initialize")

Re: Failed to initialize connection to IPv6 server

Post by sander »

I searched for "Set planned server resume" in my sabnzbd.log's, and this is the result:
in SAB 0.7, "Set planned server resume" does appear for eweka (ipv4), but not for newszilla6 (ipv6)
in SAB 0.8, "Set planned server resume" does occur for both eweka and newszilla6

Is there a difference between 0.7 and 0.8 regarding the detection of failing servers and server resuming?

Code: Select all

$ cat ~/.sabnzbd/logs/sabnzbd.log* | grep  -e resume -e "rev=" | sort

There should not be, but 7 and 8 have been in parallel for too long.
I'll have a look at it.

Re: Failed to initialize connection to IPv6 server

Does init_connect() set up a real new connection, or does it re-use an existing connection? If it re-uses, it could the connection is already gone 'below its feet'?

Code: Select all

    def init_connect(self, write_fds):
        self.nntp = NNTP(self.server.hostip, self.server.port, self.server.info, self.server.ssl,
                         self.server.ssl_type, self.server.send_group, self,
                         self.server.username, self.server.password, self.blocking, write_fds)
        self.recv = self.nntp.sock.recv

        self.timeout = time.time() + self.server.timeout

Re: Failed to initialize connection to IPv6 server

Post by sander »

Another possibility I'll investigate (long shot): I have IPv6 privacy extensions on, resulting in more than 1 IPv6 address. Maybe Python/SAB gets confused by that? Maybe an open connection on one IPv6 session, and trying a session on the another IPv6 address?

I'll turn off privacy extentsions and see what happens.

EDIT:

turned them off in /etc/sysctl.d/10-ipv6-privacy.conf, and now just one IPv6 address on WLAN0. I'll report back if that changes anything
