This software needs a working network adapter. You can install a Microsoft Loopback adapter.
|
||||
(Windows XP users: remeber to reboot after the installation procedure).
|
||||
(remeber to reboot after the installation procedure).
|
||||
|
||||
In order to install this kind of device in Windows 7, use
|
||||
devcon utility (you can download it from Microsoft website).
|
||||
|
||||
> devcon.exe install %windir%\inf\netloop.inf *msloop
|
||||
|
||||
|
||||
This utility can be used in conjunction with the uip6-bridge or the rpl-border-router
|
||||
(the latter on Windows Vista and later only).
|
||||
|
||||
|
||||
An example of usage with the RPL border router:
|
||||
wpcapslip6 -s COMXX -b aaaa:: -a aaaa:1::1/128 02-00-00-00-00-01
|
||||
|
||||
where 02-00-00-00-00-01 is the MAC address of the local network adapter.
|
||||
-a aaaa:1::1/128 can be omitted if an IP address is already set
|
||||
to the network adapter.
