dns resolver - unbound

doblezero

After I upgraded to 2.4.3 unbound stopped working. I've upgraded to 2.4.4 since but the issue persists.

Version 2.4.4-RELEASE-p2 (arm)
built on Wed Dec 12 14:40:29 EST 2018
FreeBSD 11.2-RELEASE-p6

When i try and start unbound the following happens.
The following input errors were detected:

The generated config file cannot be parsed by unbound. Please correct the following errors:
/usr/local/lib/libpython2.7.so.1: unsupported file layout

Below are the involved library files.

Is there any way to get unbound working again.

Thanks,

Looks no good to me.

It should be

Re install.

doblezero

Thanks for the reply Gertjan.

I'm guessing the ".libpython2.7.so.1-gdb.py.pR2774s34cMN, .libpython2.7.so.1.RCQFTgPFRLn6, and .libpython2.7.so.tYm3wvvdOyvF -> libpython2.7.so.1" files are remains from the 2.4.2 to 2.4.3 upgrade that led to the loss of unbound functionality.

My unit is a Netgate SG-1000. I was really trying to avoid re-flashing to get full functionality back.

I'll attempt to reinstall once I get an OTG cable and report back.

Good Evening,

It took me a long time to get around to this, but I've finally re-flashed my SG-1000 in hopes of getting unbound to work. Unfortunately the process was unsuccessful. As I understand it, unbound is built into the firmware itself. Since a reflash did not address the issue, what other solutions can I attempt?

Thank you,

doblezero

My apologies. The image reinstall did resolve the issue. I forgot that as a work around for unbound not working, I installed dnsmasq. I forgot to turn off dnsmasq before starting unbound. Thanks for listening.
