Hi Matthew,<br>
<br>
The subnet variable is not needed in switch mode. You can remove
this line from your laptop's hosts file.<br>
<br>
"Error while writing to Generic BSD tap device /dev/tun0:
Input/output error"<br>
This means that tinc cannot write to the network interface. It
usually means that the interfaces don't exist (i.e. tuntaposx isn't
installed) or it isn't configured.<br>
<br>
If you have installed tuntaposx try this:<br>
<br>
Open a terminal, and run tinc in debug mode:<br>
:# tinc -n <vpn> -d5 -D<br>
When tinc is running, try to bring up the tap0 adapter. Open another
terminal and run the command:<br>
:# ipconfig set tap0 dhcp<br>
<br>
Hopefully, you should not see the Input/Output error anymore.<br>
<br>
Kind Regards,<br>
Mike<br>

<div>Hi Folks,</div>

</div>
<div>This has been driving me nuts all day. I've been unable to
google myself out of it. Maybe someone here can help?</div>

<div>The error pops up after I try to get DHCP going over the
link. (ipconfig set tun0 DHCP). Not that it works before I try
and do that. </div>
<div><br>
</div>
<div>Both sides seems happily connected before issuing the DHCP
command.</div>
<div><br>
</div>
<div>I've tried just about everything I can think of for the
configs. Switch on, off, bridging on and off on the server
side.. nothing seems to work. I do find it odd that under linux
the virtual device looks like this: </div>
