Dear friends,

I’m trying to use openvas-nasl to run/debug a single nasl file. However it always report redis connection error as below even if to run the very simple hello.nasl, which has only one display line.
(openvas-nasl: 5915): lib kb_redis-CRITICAL **: get_redis_ctx: redis connection error: No such file or directory.

To be commented, the same system runs well for the normal scan with openvassd/openvasmd.

So my question is: to run openvas-nasl, is there any special configuration or settings required?

Thanks and BRs,

Hi Eero,

Thank you very much for your reply!
I’m using an old version of openvas-nasl (9.0.3). After further investigation and trying, it is found that the possible reason is redis.sock was not properly configured. When I configured it to the same redis.sock as the one openvassd uses by softlink, it runs.

BTW, what do you mean “adding strace”?

Thanks again!
