Running into what i think is a docker networking issue

Featured Replies

Setting up a SABNZBD Docker after dropping the Phaze plugins. The docker installs and I get to the Wizard and enter in my usegroup providers site address and I get:

 [Errno 111] (110, '[Errno 101] Network is unreachable')

Tried multiple (i know are good) addresses and i get the same. 

 

Tried deleting the ini files and have it recreate.. Nope same. Tired the same on NZBGET docker... Same issue... so it makes me think Docker Networking??

Details about my network: ATT Uverse Gigapower Fiber -> Hardwired into DMZd Google WIFI where all it goes into a switch to the rest of the house, and the wired devices (including unraid) and wifi. All machines including UNraid (plex docker) are functioning as expected.

add network details

The container is set to use the host network, which means it is directly accessing the interface, similar as Unraid itself. When Unraid has network/internet access so should have the container.

 

Do you have any other containers running or configured with the same ports 8080 or 8090?

 

  • Author

I do not. Only 5 dockers and none on that port. AND the UPNP automatically added those 2 ports to the firewall in google wifi app.  Even if I skip and get into the settings of SAB, whenever an attempt is made to validate the link for a Usenet, I get that error immediately, behaving like it doesn't have DNS or Internet.

I don't see anything wrong in your network settings.

A minor thing, you have enabled IPv6 but your router is not giving out IPv6 addresses, though this should not be an issue.

 

You can use the 'console' function of the failing container and do the following. What is the result?

ping 8.8.8.8

 

I'm using the 'bridge' settings in Unraid. Working for 8 dockets or something

response as expected (ping reply) from that container... hmm. when I try to ping https://api.NZBPROVIDER.info/ or api.NZBPROVIDER.info/ it returns nothing. I paste that same thing in lookup tool on the web and it works fine. 

 

When i resolve the IP of the above address and then ping that IP, it works from the container. So DNS?

 

What is next step in troubleshooting?

Do you have the "--dns" parameter set for this container (see extra parameters field in advanced view) ?

  • Author

I don't, see attached, what should I have in there?

I expect no DNS setting here (extra parameters)

Here it is in advanced view, Umask? Doesn't seem to be any DNS entries. I can add, just need to know what to fill in.

Two things to check first

  1. Open a terminal session and type
    cat /etc/resolv.conf

     

  2. Open a console session of the container and type
     

    cat /etc/resolv.conf

     

Post the results.

@Mothership:~# cat /etc/resolv.conf
# Generated DNSv4 entries:
nameserver 8.8.8.8
nameserver 192.168.86.1

 

then in container..

 

sh-5.0# cat /etc/resolve.conf
cat: /etc/resolve.conf: No such file or directory
sh-5.0#

Duh :) 

 

sh-5.0# cat /etc/resolv.conf
# Generated DNSv4 entries:
nameserver 8.8.8.8
nameserver 192.168.86.1

Inside a container, you should see something like this

root@b142de55abf9:/# cat /etc/resolv.conf
nameserver 127.0.0.11
options ndots:0

sh-5.0# cat /etc/resolv.conf

nameserver 192.168.86.1

 

Ok, so mine doesn't, what does that mean?

Sorry, I was mixing up things.

In case of a host network your DNS settings are okay.

I am puzzled why it isn't working.... maybe change your DNS to a single entry and see if that works?

Not sure how to change that? Command line? Variable? suspect you think I a bit more advanced than I really am.
