AnyWhereUSB/2 and port scanning

We have just noticed that if you port scan an AnywhereUSB/2 device, with nmap for example, it goes into an endless reboot cycle. The only way out is to pull the power cord!

Is this behaviour expected?


What is the exact syntax you’re using with nmap?


We have been using the Zenmap GUI in two modes:

Intensive Scan:
nmap -T4 -A -v -PE -PS22,25,80 -PA21,23,80,3389

This causes a single reboot.

Slow Comprehensive Scan:
nmap -sS -sU -T4 -A -v -PE -PP -PS21,22,23,25,80,113,31339 -PA80,113,443,10042 -PO --script all

This is the one that puts the AnyWhereUSB/2 into an endless reboot cycle!

FYI the Firmware version on the device is 1.32.0626

Hope this helps!
