Scans end with "no hosts available" (ICMP error at the target firewall)

GVM versions

gsad: (‘gsad --version’)

Operating system:
Ubuntu 20.04.3 LTS
Kernel: (‘uname -a’)
Linux v22019091542698153 5.4.0-91-generic #102-Ubuntu SMP Fri Nov 5 16:31:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Installation method / source:

The installation was fine without any errors.
Now, when trying to scan a target, the scan ends with “no hosts available”.
I can see, that our firewall is reporting an icmp error. Although a manual ping out of the ubuntu console is possible without any problem against the scan target.

Im out of ideas. The older gvm version 20 ran without any problem. From the same host against the same target just a few days ago. I reinstalled ubuntu 20.04 completly and followed the tutorial at to install openvas.

Even if i set the alive test to “consider alive”, the firewall is reporting an incoming icmp error.

Can anyone help me please? The available log files at /var/log/gvm arent reporting any helpful information. Why is “consider alive” still ending in icmp requests? Is something wrong with the scanner?

Thanks in advance

Hi @kmuc and welcome to the forum :slight_smile:

Just to see if the scanner itself is working correctly, what happens when you scan localhost?
