Unfortunately Cloud Discovery has an issue in 4.0.0. If you need Cloud Discovery and cannot wait for 4.0.1, please perform the below.
Linux
mysql -u openaudit -popenauditpassword openaudit -e "ALTER TABLE networks CHANGE gateways gateways VARCHAR(250) NOT NULL DEFAULT '';"
Windows
c:\xampp\mysql\bin\mysql.exe -u openaudit -popenauditpassword openaudit -e "ALTER TABLE networks CHANGE gateways gateways VARCHAR(250) NOT NULL DEFAULT '';"
Then patch the file open-audit/code_igniter/application/models/m_discoveries.php
In the "create" function, at about line 78, find the below lines
if ($data->type !== 'subnet' && $data->type !== 'active directory') { $data->type = ''; }
and change them to
if ($data->type !== 'subnet' && $data->type !== 'active directory' && $data->type !== 'cloud') { $data->type = ''; }
Apologies for the inconvenience.
