Title: Self Diagnosis
|
||
|
|
|
||
|
|
|
||
|
|
Windows
|
||
|
|
-------
|
||
|
|
|
||
|
|
*Before anything, make sure you have started OpenVPN as Administrator and that your
|
||
|
|
config files exist in `C:\Program Files\OpenVPN\config\`.*
|
||
|
|
|
||
|
|
### netsh.exe error
|
||
|
|
|
||
|
|
If you find lines like those in your OpenVPN log:
|
||
|
|
|
||
|
|
NETSH: C:\Windows\system32\netsh.exe interface ipv6 set address Local Area Network
|
||
|
|
ERROR: netsh command failed: returned error code 1
|
||
|
|
|
||
|
|
This error is really frequent on Windows and seem to happen because of
|
||
|
|
a OpenVPN problem with netsh.exe and IPv6.
|
||
|
|
To fix it, rename your network connection to avoid spaces,
|
||
|
|
for example "Local Area Network" to "lan".

### Multiple TAP-Windows adapters
|
||
|
|
|
||
|
|
Error: When using --tun-ipv6, if you have more than one TAP-Windows adapter, you must also specify --dev-node
|
||
|
|
Exiting due to fatal error
|
||
|
|
|
||
|
|
That one can happen when you have multiple TAP-Windows adapters, most of the
|
||
|
|
time because of another software using TAP.
|
||
|
|
|
||
|
|
To fix it, open a command prompt (Shift+Right click) in your OpenVPN directory
|
||
|
|
(where openvpn.exe is), and run:
|
||
|
|
|
||
|
|
openvpn.exe --show-adapters
|
||
|
|
|
||
|
|
This will list your TAP adapters.
|
||
|
|
Then, open your ccrypto.ovpn configuration file with notepad and add this on a
|
||
|
|
new line:
|
||
|
|
|
||
|
|
dev-node [name]
|
||
|
|
|
||
|
|
Replace [name] by your TAP adapter name.
|
||
|
|
|
||
|
|
|
||
|
|
### Still doesn't work
|
||
|
|
|
||
|
|
If you still cannot use the VPN, please go to the [Support page](/page/help)
|
||
|
|
and we'll do our best to help you.
|
||
|
|
Please also send us your OpenVPN logs.

GNU/Linux
|
||
|
|
---------
|
||
|
|
|
||
|
|
### I have a ".ovpn" file but I need a ".conf"!
|
||
|
|
You just have to change the extension by renamming the file.
|
||
|
|
.conf is more commonly used on GNU/Linux, but it's the same as the .ovpn file.
|
||
|
|
|
||
|
|
|
||
|
|
### I'm unable to use your VPN with Network-Manager.
|
||
|
|
First, check that you have properly created the profile (tutorial to come).
|
||
|
|
If it's the case, before anything else, let's make sure that OpenVPN itself is working with the following command:
|
||
|
|
`sudo openvpn --config ccrypto.conf`
|
||
|
|
(make sure to replace "ccrypto.conf" by the actual name of your configuration file)
|
||
|
|
|
||
|
|
### I'm connected but cannot ping google.com
|
||
|
|
Try to `ping 8.8.8.8`: if it works then your computer doesn't use the right DNS server.
|
||
|
|
Add `nameserver 10.99.0.20` at the beginning of /etc/resolv.conf **once the connection is made**.
|
||
|
|
Else, continue reading.
|
||
|
|
|
||
|
|
|
||
|
|
### It still doesn't work!
|
||
|
|
Using the `ip route` command, make sure you have, alongside with other lines, the following:
|
||
|
|
|
||
|
|
0.0.0.0/1 via 10.99.2.1 dev tun0
|
||
|
|
10.99.0.0/24 via 10.99.2.1 dev tun0
|
||
|
|
10.99.2.0/24 dev tun0 proto kernel scope link src 10.99.2.18
|
||
|
|
128.0.0.0/1 via 10.99.2.1 dev tun0
|
||
|
|
199.115.114.65 via 192.168.1.1 dev wlan0
|
||
|
|
|
||
|
|
These values might (and for some, will) change a little depending on your configuration (for example: wlan0 → eth0, 192.168.1.1 → 192.168.42.23, etc.).
|
||
|
|
If you don't have every one of these lines, kill OpenVPN and fire it again or add the routes by hand using `ip route add`.
|
||
|
|
If you don't know how to do it, it would be best to come ask on IRC (we will need the output of both `ip addr` and `ip route`,
|
||
|
|
please paste them into https://paste.cubox.me and just give us the link to the paste).
|
||
|
|
|
||
|
|
|
||
|
|
### I've tried everything but nothing seems to work! T_T
|
||
|
|
Ok… I guess now you can come [ask us on IRC](/chat) (but remember to stay a while, we're not payed professionnal, we might not be around at a given time but we will answer later on).
