Unbound can't start after snapshot update (new thread!)

wagonza

ok all fixed - reinstall. Also fixed some other startup errors.

iFloris

Sorry wagonza, but unbound still doesn't fully work for me.

Unbound is reporting the following error over and over again:```
php[2147483647] : The command '/usr/local/sbin/unbound-control forward ' returned exit code '1', the output was '[1314033304] unbound-control[45855:0] debug: address 127.0.0.1 port 953 [1314033304] unbound-control[45855:0] error: connect: Operation timed out'


Also, when clicking save in the webconfigurator, everything php-related seems to lock up for a while.
Ssh still works.
After a while, the webconfigurator starts working again and I see the following line in the syslog:```
kernel: pid 62904 (php), uid 0: exited on signal 11 (core dumped)

Removing the testing v6 redirects helps unbound start again.

wagonza

You did reinstall the package right?

iFloris

To be certain I just reinstalled Unbound again, although I think I did.
When I have v6 overrides in dns forwarder, unbound fails to start without error messages.
It's not a big deal, as the v6 overrides are merely out of curiosity and to drive global v6 traffic a bit higher.

wagonza

Hrmm odd if i add a v6 override, for example:

v6 google.com 2800:3f0:XXX:XXX::1014

And restart unbound it is fine.
Do me a favour please, log in via ssh and execute a unbound-checkconf - it should return "unbound-checkconf: no errors in /usr/local/etc/unbound/unbound.conf"

iFloris

Unbound gives me a no errors reply, just as you said it should. I'll try and enable my testing v6 forwards one by one to see if there is a specific scenario which causes unbound to stop working. Thanks for your help so far!

Have you managed to test the v6 forwards?

iFloris

Hello Wagonza,

Unbound still gives me errors in the log but works with the forwards.
Adding the forwards one by one and reloading unbound in the ssh-console has helped unbound start properly.

Thanks for all your help!

What error did you see in the logs, the same timeout one? Can you do me a favour please and pm me the xml of the unbound section of your config.xml?

Thanks

iFloris

The very same. I will send you the unbound section(s) of my config.xml.

Edit: Sent.

wagonza

Thanks, got it - will go through it a little later and let you know.

wagonza

Problem sorted with host over rides that have empty host values. So just reinstall the package. Otherwise any other problems, please open up a new thread.

iFloris

Having set some v6 forwards yesterday, I can confirm that the new fixes work as expected.
Thanks a lot wagonza!

wagonza

wicked! Only v6 ACLs now left…

johnpoz

Sweet!! ipv6 ACLs are NEXT ;)

wagonza

Finally committed support for IPv6 acls :P I have also updated the package to latest Unbound version 1.4.13. So give it a couple of hours while the package builder is building the new port.

johnpoz

Sweet! Can remove them from my custom options section, which is how I have been adding them now.

See it listed already, installing now

Looks like you forgot a _ in the allow_snoop

php: /unbound_acls.php: The command '/usr/local/sbin/unbound-control start' returned exit code '1', the output was '/usr/local/etc/unbound/unbound.conf:67: error: unknown keyword 'snoop' /usr/local/etc/unbound/unbound.conf:68: error: unknown keyword 'snoop' /usr/local/etc/unbound/unbound.conf:69: error: unknown keyword 'snoop' /usr/local/etc/unbound/unbound.conf:70: error: unknown keyword 'snoop' read /usr/local/etc/unbound/unbound.conf failed: 4 errors in configuration file [1317328224] unbound[30144:0] fatal error: Could not read config file: /usr/local/etc/unbound/unbound.conf'

So I have an ACL that allows snoop, but in the .conf file its put in as "allow snoop" which killed my unbound now it can not start. Trying to manually edit the ubound.conf now so I can get unbound to start.

wagonza

Cool let me know if you get any problems.

johnpoz

just edited my last post – looks like a problem ;)

wagonza

bah! and i did test that specifically. hang 5.
