Redis is configured for the UNIX socket, and so the ospd-openvas. When starting the ospd-openvas, it complains about the redis ctx isnt provided. The NVT’s are successfully loaded and are correctly into redis. Resetting the nvt’s and restarting ospd-openvas loads the NVT’s correctly, but after a few minutes the same error arises.

ospd-openvas -s /usr/local/etc/openvas/ospd.conf -f -L DEBUG

What could be the cause of this error?

I had a similar issue with gvmd installed alongside of openvasmd, while redis db wasn’t flushed properly. Stop gvmd & ospd-openvas completely, then flush redis database with “redis-cli flushall” then restart everything.

In my case that fixed the issue.


Unfortunately, in my case this doesnt solve the issue. Meanwhile I’ve build a second VM and followed someone else’es manual, and I’ve got this up and running. So I will mark your anwser as the correct one.

The new install does however have a problem which until now I’m unable to solve. Gvmd stuck at 100% with no CVE's and CPE's

It is very likely that this an redis issue. Please check your redis config.

Hi Bricks,

For someone who is completely new to Greenbone systems / OpenVAS, what would your recommendation be for redis config (or redis-openvas.conf, I have both) as I am having the same issue even though my config is stock standard?


An example redis config can be found here https://github.com/greenbone/openvas/blob/master/config/redis-openvas.conf

This config should work in most cases for SOHO networks.


Thank you so kindly Björn, much appreciated!

Check also you’re using strictly the same gvmd / ospd / openvas git version. Having different git revision talking to each other may produce this issue also.
