Re: [Openvpn-devel] CreateFile failed on TAP device

2004-11-06 Thread Hans Fugal 
Ahh, well now I know what that error means if someone accidentally
disables the TAP device in the future.

BTW is there a command-line way to rename the tap device to something
like OpenVPN TAP Device N or something, rather than Local Area
Connection N? It would make it easier for phone support. I ask for
command-line because that could be done automatically in my installer.

Attached is her full log. She was connecting just fine yesterday. I've
had her stop and start via openvpn gui, with the same results (this
log file is from the start after the stop)

I don't know what to tell her, other than to uninstall, reboot, and
reinstall. Does anyone have any other advice?


Ahh, now I remember. This was asked a few weeks ago, and then someone gave 
the tip to check if the TAP device had misstakenly been disabled.


I just checked, and you do get exactly that message if the device is 
disabled.


I guess reinstalling openvpn re-enables the interface, so that explains 
why that would solve the problem.

Yes, and that's what we ended up doing.

# Her config file:
dev tun
client
remote 204.96.22.195

ca wencor-cacert.pem
cert user.pem
key  user.pem

keepalive 10 60
comp-lzo
mute 5
verb 4

In addition, I'm pushing a route and a few dhcp-options.

> Does she have multiple tun/tap interfaces installed?

She shouldn't, if she followed my instructions properly.

> If she run ipconfig can she see the device with the GUID listed above?

She had a hard time finding All Programs in the Start Menu. :-)

> Does it fail evert time she tries to connect now?

Yes, it was failing every time.

> Did she make any changes when it stopped working? Any new patches applied?

She claimed she didn't make any changes, and she certainly wouldn't
have been applying patches or reinstalling components. She may have
run the original installer again, that's a possibility. I believe she
was trying to start another openvpn gui instance, FWIW.

It's a windows system, right? Reinstall and reboot is always a solution on 
such a beast ;-)


Is she using --dev-node to specify the tun/tap interface?

Does she have multiple tun/tap interfaces installed?

If she run ipconfig can she see the device with the GUID listed above?

Does it fail evert time she tries to connect now?

Did she make any changes when it stopped working? Any new patches applied?
