Tech FAQ
Scan process very slow
The performance of a scan depends on various aspects.
-
Several port scanners were activated concurrently.
If your are using a individual Scan Config please take care to select only a single port scanner in the famility "Port Scanner". Of course "Ping Host" can still be activated.
-
Unused IP addresses are scanned very time-consuming.
In a first phase for each IP address it is detected whether a active system is present. In case it is not, this IP will not be scannned. Firewalls and other systems can prevent a sucessful detection. The NVT "Ping Host" (1.3.6.1.4.1.25623.1.0.100315) offers to fine-tune detection.
On scanned target systems appears a VNC dialog
When testing port 5900 or configured VNC port, a window appears on scanned target system that asks the user whether to allow the connection. This was observed for UltraVNC Version 1.0.2.
Solution: Exclude port 5900 or other configured VNC port from target specification. Alternatively upgrade to a newer version of UltraVNC would help (UltraVNC 1.0.9.6.1 only uses baloons to inform users).
After Factory Reset neither Feed-Update nor System-Upgrade works
(This is not relevant for virtual appliances where no factory reset is integrated anyway)
A Factory Reser deletes the whole system including the subscription key. The key is mandatory for Feed-Update and System-Upgrade.

Reactivate subscription key:
A backup key is delivered with each GSM appliance, usually stored on a USB Stick and lebelled with the key ID. Use this key to reactivate the GSM. The activation is described in the SetUp Guide of the respective GSM type.
-
Update system to current version:
Depending on the age of the factors emergency system you now need to execute the respective upgrade procedure. Details can be found here: GSM Upgrade.
