Openvpn

Steps to setting up a VPN on a Ubuntu server

1. First install the openvpn software with the command.

aptitude install openvpn

all of the files will be located in the:

/etc/openvpn

2. to make things easier you can copy the dir "easy-rsa" from the samples dir to the current dir of "/etc/openvpn".

cp -R /usr/share/doc/openvpn/examples/easy-rsa/ ./

3. after copying the easy-rsa dir switch to easy-rsa/2.0/ where we will build the Certificates of Authority with some scripts provided.

4. edit the vars file and add in information for KEY_COUNTRY, KEY_PROVINCE, KEY_CITY, KEY_ORG, and KEY_EMAIL parameters. save and exit out back to easy-rsa/2.0/.

Nano vars

then after you edit the file use the command source vars

5. now we are going to run some scripts starting with the clean-all

./clean-all

followed up by the

./build-ca

the text showing up should look somewhat like this

this picture will not look 100% like your printout based on the facts that you changed the country, city etc from the vars file, and the CA key is finished.

6. time to make the server key with the script

./build-key-server server

you will be prompted the same message as above but you will have the added Sign the Certificate which you want to say yes.

7. the last key required is the client key and is created by doing

./build-key client1

this will create a key for the first client and if you want more just name it "client2" for the next one. also don't forget the get the client key signed.

8. the DH(Diffie Hellman) parameters need to be genterated for the OpenVPN server

./build-dh
