"Error in host specification" when creating a Target with larger than /24

[Barry Gould]

Hi,

I'm trying to create a scan target for 10.40.0.0/16 or /15 or /14, and it keeps failing with 'Error in host specification' unless I change it to /24.

Why?!

This is on CentOS 6, with current packages.

Thanks,
Barry

/24 is the largest net you can use for target. You will have to split up
anything larger into /24 subnets. Since a /14 will be end up being quite
a few /24 nets you may want to look at the OMP protocol
http://www.openvas.org/omp-5-0.html#command_create_target and create the
targets and tasks via script instead of typing them in manually.

Hi,

Thanks for your reply.

Is this for a technical/performance reason, or could it be fixed to allow larger network specifications?

Thank you,
Barry
