Hi, when choosing the category for a topic please try to have a look at the category description for each category first:
The current used category is/was Vulnerability Tests - Greenbone Community Forum (Description: About the Vulnerability Tests category - Vulnerability Tests - Greenbone Community Forum) which is about vulnerability tests (the so called “NASL scripts”).
Based on your questions it seems to be relevant to the OpenVAS/GVM setup and not a vulnerability test itself. For such questions the https://community.greenbone.net/c/gse (Description: About the Source Edition (GSE) category) needs to be chosen.
I have moved the topic to the correct category for now. It could be possible that the info above is made more prominent / easier to find in the future.
Comparing this versions with the latest ones of GVM-9 (end-of-life, initial release 2017-03-07) - Greenbone Community Edition - Greenbone Community Forum those are quite outdated.
Please update to the recent releases and try again.
