I've got dude set up and running. I can consistently replicate this crash.
Add an address list, call it 'Customers'
Add to the address list the following blocks:
- 125.254.2.0/24
125.254.10.0/24
202.168.40.0/24
202.168.57.0/24
202.191.8.0/22
- Scan networks: 172.16.0.0/24
Add Networks to Auto Scan: checked
Black List: Customers
Device Name Preference: DNS to SNMP to NETBIOS to IP
Discovery Mode: fast (Scan by ping)
Recusrive Hops: checked, 3
Layout Map after Disvcovery Complete: checked
I've also tried
- Scan networks: 172.16.0.0/24
Add Networks to Auto Scan: unchecked
Black List: Customers
Device Name Preference: DNS to SNMP to NETBIOS to IP
Discovery Mode: fast (Scan by ping)
Recusrive Hops: checked, 3
Layout Map after Disvcovery Complete: checked
However
- Scan networks: 172.16.0.0/24
Add Networks to Auto Scan: checked
Black List: Customers
Device Name Preference: DNS to SNMP to NETBIOS to IP
Discovery Mode: fast (Scan by ping)
Recusrive Hops: checked, 3
Layout Map after Disvcovery Complete: unchecked
If I do the same scan without the blacklist it returns all the hosts correctly and does not crash
