no route to host but ping

Post by frelacia »

Hi,

I´ve installed sabnzbd+ v0.5.6. I´m already connected to gogonet ipv6. I´m able to ping the newsserver:

Code: Select all

ping6 reader.ipv6.xsnews.nl

but after starting sabnzbd+ I get the message "no route to host" like this:

Two possible causes:

1) usenet traffic over your IPv6 tunnel is blocked, OR
2) your python/sabnzbd does not understand IPv6

But first: is this a full Debian/Ubuntu on a PC, or on a NAS/small device?

Things to check:
What does "telnet reader.ipv6.xsnews.nl 119" give you?
What happens when you add newszilla6.xs4all.nl (no account needed) to SAB's servers?

yes, it is a full Debian/Ubuntu on a PC.

the telnet request gave: 

Code: Select all

telnet reader.ipv6.xsnews.nl 119
Trying 2001:67c:174:101::2...
Trying 2001:67c:174:101::3...
Trying 2001:67c:174:101::4...
Trying 2001:67c:174:101::5...
telnet: Unable to connect to remote host: No route to host
The behavior with the other server is the same like reader.ipv6.xsnews.nl :

Code: Select all

OK. Let's check whether gogonet is blocking NNTP traffic:

disable gogonet (via /etc/init.d/???)
enable teredo/miredo: sudo apt-get install miredo
check gogonet is disabled (see your ifconfig), check teredo/miredo is working via http://test-ipv6.com/ ; you should have a 2001:0: address
If everything is OK, restart SABnzbd and check if it works ....


Here's the proof that xsnews works over teredo/miredo:

Code: Select all

sander@quirinius:~$ telnet reader.ipv6.xsnews.nl 119
Trying 2001:67c:174:101::2...
Connected to reader.ipv6.xsnews.nl.
Escape character is '^]'.
201 reader.ipv6.xsnews.nl NNRP Service Ready (no posting).
quit
205 Transferred 60 bytes in 0 articles, 0 groups.  Disconnecting.
Connection closed by foreign host.

PS:

If disabling gogonet is too difficult for you, here's a nice-to-know:

if you have multiple (ipv6) interface because of multiple ipv6 tunnels (miredo AND gogonet), you can specify the ipv6 tunnel you want to test with telnet using the parameter -b:

telnet -b 2001:0:abcd: ipv6.google.com http

telnet -b 2001:0:abcd: newszilla6.xs4all.nl nntp

You have to fill out your local IPv6 address, which of course depends on the tunnel (interface)

ok, now it works.

I disabled the gogonet tunnel via ifconfig:

Code: Select all

sudo ifconfig tun down
(tun is the name of the gogonet interface)

After installing the other tunnelclient (miredo) it works
Thank you very much!

OK. Conclusion: gogonet is blocking nntp 119 traffic.  :(

One thing to check: after a reboot, check the gogonet tunnel is not back again. Maybe better to deinstall gogonet.
