How to install VPN service server?

frenchn00b · 09-04-2009, 03:30 PM

Debian Lenny, Stable:

So I followed this procedure:

Step 1:

* Copy files to the /etc/openvpn/easy-rsa/ directory

sudo mkdir /etc/openvpn/easy-rsa/
sudo cp -R /usr/share/doc/openvpn/examples/easy-rsa/2.0/* /etc/openvpn/easy-rsa/

Step 2:

* Edit /etc/openvpn/easy-rsa/vars

sudo vi /etc/openvpn/easy-rsa/vars

Change these lines at the bottom so that they reflect your new CA.

export KEY_COUNTRY="US"
export KEY_PROVINCE="CA"
export KEY_CITY="SanFrancisco"
export KEY_ORG="Fort-Funston"
export KEY_EMAIL="me@myhost.mydomain"

. ./vars
./clean-all
./build-ca

chmod og-rxw /etc/openvpn -R

./pkitool --initca ## creates ca cert and key

./build-key-server server

/etc/init.d/openvpn start

openvpn is into the ps aux

but nmap ip

gives no port

what is wrong?

cd keys
openvpn --genkey --secret ta.key ## Build a TLS key

# create the dh1024.pem
openssl dhparam -check -text -5 1024 -out dh1024.pem
I copied this file to /etc/openvpn

cd /etc/openvpn/easy-rsa
cp server.crt server.key ca.crt dh1024.pem ta.key ../../

what is done not well, what I forgot?

I can login with my other machine to my server

but wehen I start hte server it does not fail. seem sto work,
but windows see nothing.

How to give the passwords to my users?

Please Help

Hello,

Do you mean that you cannot connect from a Windows based computer to your OpenVPN server when you say Windows see nothing? You have to configure your Windows machine also, for example check out this Howto1 or Howto2 tutorial for how to set up Windows to communicate with your OpenVPN server.

Also can you verify that you have your TUN device installed/configure/up?

Kind regards,

Eric

setup openVPN server?
You are going to want to set up a bridged vpn server, something I've never done. However, I can walk you through the steps to set up the server/client keys if you would like. Mine is routed and I only use it to access files via a samba share. Unless I'm mistaken the differentiation between routed and bridged server is in the server/client config files...so lets get you there and hopefully someone else can add to this, or we can struggle through it.
Additionally, I only did the basic server installation so I'm working from command line only.

Most of the posts available in the forums advise people to follow the How-To on the openvpn.net site. I agree but will try to make it a bit more simple. I hope I'm not wasting your time with the simplicity of my instructions. Also, I'm assuming you are vaguely familiar with vi. If not use gedit or whatever you like. Also here is a nice concise vi guide:

http://www.eng.hawaii.edu/Tutor/vi.html

First you need to install openvpn and openssl to do so from the command line:

Code:

sudo apt-get install openvpn

and

Code:

sudo apt-get install openssl

Next you need to change directories to the easy-rsa directory:

Code:

cd /etc/openvpn/easy-rsa

If there are no subdirectories in the openvpn directory copy the easy-rsa directory from /usr/share/doc/openvpn/examples/easy-rsa to the /etc/openvpn directory

First go to the examples directory

Code:

cd /usr/share/doc/openvpn/examples

Then copy the easy-rsa directory to the /etc/openvpn location

Code:

sudo cp -r easy-rsa /etc/openvpn

You should now edit the vars file located in this newly created easy-rsa directory:

Code:

sudo vi vars

Change the fields mentioned in the openvpn.net site. Next, while in the easy-rsa directory enter the following:

Code:

. ./vars

Note the space between the periods. Next enter:

Code:

sudo ./clean-all

Then enter:

Code:

sudo ./build-ca

Note that when you do this you must enter something for the "common name."

Now enter the following inserting your server's name:

Code:

sudo ./build-key-server yourserver's name here

When it asks for the common name enter your server's name. Next build your client key (again while in the easy-rsa directory).

Code:

sudo ./build-key client name here

If you want the server to prompt you for a password before you can connect to the vpn server enter:

Code:

sudo ./build-key-pass client name here

Repeat the step you used to create the client key for the number of keys you want to create, chagning the client name for each

Now you build the Diffie Hellman parameters:

Code:

sudo ./build-dh

All the server keys and client keys are in the keys directory which is in the easy-rsa directory. You will need to be root to gain access to the keys directory:

Code:

sudo su

Copy the client keys: ca.crt, client.key, client.csr, client.crt to the client computer. You will always have a ca.crt file, the client files will be named whatever name you gave the client.

You now need to create the server configuration file. To do this (I doubt it is the best way but it worked) I copy/pasted the sample server config file from the openvpn.net site into a newly created file named server.conf inside the /etc/openvpn directory.

Code:

sudo vi /etc/openvpn/server.conf

This will open an empty file, you can then paste the copied sample server.conf into it.

From here you need to edit the server.conf file for a bridged server...which I haven't ever done.

For the initial start of the daemon do the following while in the directory containing your server config file:

Code:

openvpn --daemon --config configfilenamehere

If this was helpful and you want/need help with setting things up on the client side let me know.
If there is anything that is unclear please let me know. If I get some time I'll look up things for the bridged server part and see if I can offer any further help. Additionally, here are a few websites that may offer help:

# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have VPN access,
# use the subdirectory "ccd" for client-specific
# configuration files (see man page for more info).

# EXAMPLE: Suppose the client
# having the certificate common name "Thelonious"
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
;client-config-dir ccd
;route 192.168.40.128 255.255.255.248
# Then create a file ccd/Thelonious with this line:
#   iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN.  This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.

# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
#   ifconfig-push 10.9.0.1 10.9.0.2

# Suppose that you want to enable different
# firewall access policies for different groups
# of clients.  There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
#     group, and firewall the TUN/TAP interface
#     for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
#     modify the firewall in response to access
#     from different clients.  See man
#     page for more info on learn-address script.

# (The OpenVPN server machine may need to NAT
# the TUN/TAP interface to the internet in
# order for this to work properly).
# CAVEAT: May break client's network config if
# client's local DHCP server packets get routed

#   iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN.  This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.

# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
#   ifconfig-push 10.9.0.1 10.9.0.2

# Suppose that you want to enable different
# firewall access policies for different groups
# of clients.  There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
#     group, and firewall the TUN/TAP interface
#     for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
#     modify the firewall in response to access
#     from different clients.  See man
#     page for more info on learn-address script.
;learn-address ./script

# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the VPN, causing
# all IP traffic such as web browsing and
# and DNS lookups to go through the VPN
# (The OpenVPN server machine may need to NAT
# the TUN/TAP interface to the internet in
# order for this to work properly).
# CAVEAT: May break client's network config if
# client's local DHCP server packets get routed
# through the tunnel.  Solution: make sure
# client's local DHCP server is reachable via
# a more specific route than the default route
# of 0.0.0.0/0.0.0.0.
;push "redirect-gateway"

# Certain Windows-specific network settings
# can be pushed to clients, such as DNS
# or WINS server addresses.  CAVEAT:
# http://openvpn.net/faq.html#dhcpcaveats
;push "dhcp-option DNS 10.8.0.1"
;push "dhcp-option WINS 10.8.0.1"

# Uncomment this directive to allow different
# clients to be able to "see" each other.
# By default, clients will only see the server.
# To force clients to only see the server, you
# will also need to appropriately firewall the
# server's TUN/TAP interface.
;client-to-client

# Uncomment this directive if multiple clients
# might connect with the same certificate/key
# files or common names.  This is recommended
# only for testing purposes.  For production use,
# each client should have its own certificate/key
# pair.
#
# IF YOU HAVE NOT GENERATED INDIVIDUAL
# CERTIFICATE/KEY PAIRS FOR EACH CLIENT,
# EACH HAVING ITS OWN UNIQUE "COMMON NAME",
# UNCOMMENT THIS LINE OUT.
;duplicate-cn

# The keepalive directive causes ping-like
# messages to be sent back and forth over
# the link so that each side knows when
# the other side has gone down.
# Ping every 10 seconds, assume that remote
# peer is down if no ping received during
# a 120 second time period.
keepalive 10 120

# For extra security beyond that provided
# by SSL/TLS, create an "HMAC firewall"
# to help block DoS attacks and UDP port flooding.
#
# Generate with:
#   openvpn --genkey --secret ta.key
#
# The server and each client must have
# a copy of this key.
# The second parameter should be '0'
# on the server and '1' on the clients.
tls-auth ta.key 0 # This file is secret

# Select a cryptographic cipher.
# This config item must be copied to
# the client config file as well.
;cipher BF-CBC        # Blowfish (default)
;cipher AES-128-CBC   # AES
;cipher DES-EDE3-CBC  # Triple-DES

# Enable compression on the VPN link.
# If you enable it here, you must also
# enable it in the client config file.

# By default, log messages will go to the syslog (or

how to make it so that my new client gets the ip, a new ip in my network internal from my routeur ?

I would like also that ipconfig displays this connection

how can it be possible?

frenchn00b · 09-09-2009, 03:40 PM

any help what is the tun and tap?

Quote:

Naming Linux/Windows vs. RouterOS

There are two interface types within OpenVPN, that are used.

* tun, RouterOS defines this as ip.
* tap, which is needed for bridge mode gateways. RouterOS defines this as ethernet.

I still dont understand
sorry
