#Script written by Eric Jodoin
\ No newline at end of file

Hi guys! Sorry I am still a Linux noob and just can't find the problem with the script.

I was using the latest script, however I keep on getting the following error:

Please enter an existing Client Name:
client1
[ERROR]: Client Public Key Certificate not found: client1.crt

However, the client1.crt file is located in the /keys folder.

Any ideas? Thank you very much!

I'm busy following the tutorial now, and encountered the same problem you did - the key existed in the folder, but ./MakeOVPN.sh returned Client Public Key Certificate not found.

I ended up succeeding, but I don't know what of the following worked. In order -

1. Replace the code above with this newer version, save and commit - https://gist.githubusercontent.com/coolaj86/4120d90e57d1d01cd59f/raw/MakeOpenVPN.sh

2. Reboot the Pi

3. Open a terminal or go in with ssh

4. sudo su

5. cd /etc/openvpn/easy-rsa/keys/

6. Execute the script

I suspect I was either no in the right directory, or that the Pi needed a reboot for something to take effect.

Hope it works for you!

@riazarbi

It was step 5 that did if for you. If you weren't in the right directory, it wouldn't be able to find those files since the script is set up to look in the current working directory only for those files. You could hardcode the full path if you wanted to be able to run the script from elsewhere.

Hi Lauren and others

Thank you very much for your code and tutorial!!!
I was not able to get OpenVPN working on a new Jessie install, but did find an auto-install fork (not actually a fork, but which credits your work). I ran it and it performs the install, server cert and client cert. I thought you and others may be interested in this approach, so I am linking to it here:

Thanks

Commented out 2 lines that kept throwing an error.
https://gist.github.com/Trumpy/9a1326a2992028a5a8e3

just followed this, i think using the latest script posted by trumpy

got "PolarSSL cert certificate is undefined" from my iphone

its because my Default.txt file needed a line break at the end (Or another script update)

basically <ca> needs to be on its own line in the ovpn file

This is what got me passed the ta.key not found problem. Little weary that the first part of the installation did not do something it should of, but now I have a .ovpn file.

For some reason I did not have a ta.key file in the first place so I ran this

openvpn --genkey --secret /etc/openvpn/easy-rsa/keys

this will create the ta.key...

Using the scripts changes from coolaj86 and running the script from /etc/openvpn/easy-rsa/keys worked.

It created my .ovpn file.

On to the next step, hope that helps...

How would I make this so I am able to use my VPN from any outside network?

I'm getting ta.key not found, this error exactly: [ERROR]: tls-auth Key not found: ta.key

I think in the line 46 a "#" is missing.
