Hello everyone!

We have GVM 22.4 running on Ubuntu 22.04. Installation went without issue, and my question pertains to scans.

When I perform a scan against my target with All TCP and Nmap top 100 UDP, the scan completes as expected.
When I perform a scan against the same target using All IANA assigned TCP and UDP, the scan stays at 0%

Checking gvmd.log shows the following:

Here you can see again that QA Test #8 (the lighter All TCP and Nmap top 100 UDP scan) was created, started, and run. There were some errors (“Failed to parse client xml: Command unavailable”/“write_to_client_unix: failed to write to client: broken pipe”) but the scan completed.

Beneath that you can see the creation/execution of QA Test #9 (All IANA assigned TCP and UDP). The same errors previously mentioned are there - but after an hour of run time, the scan is still at 0%.

Finally, here’s the tail -f /var/log/gvm/*log:

Any ideas what’s going on here? Happy to supply any additional information - thanks in advance for your time and assistance!

Missed this one:

@Renevant well. scans can take long time, just wait. how much memory and cpus are installed on machine?

The scanner in question is a VM using 8 vCPUs and 16GB of memory - but you’re right - the scan did finish, it just took some time - approximately 2.5 hours before it started. I don’t recall v20.8 taking that long, but I could be wrong.

This should be expected when scanning all 65535 UDP ports due to the nature of the UDP protocol. More info from 17 Managing the Performance — Greenbone Enterprise Appliance 22.04.17 documentation :

In some situations with port throttling, scanning all TCP and UDP ports can take up to 24 hours or more for a single system.
