Setup SSL Tunnel Using Stunnel on Ubuntu

The Stunnel program is designed to work as an SSL encryption wrapper between remote client and server. It can be used to add SSL functionality.

What Stunnel basically does is that it turns any insecure TCP port into a secure encrypted port using OpenSSL package for cryptography.

1.Update & Upgrade Ubuntu

apt-get update && apt-get upgrade

2.Install Stunnel on VPS

apt-get install stunnel4 -y

3.Create SSL Certificate

openssl genrsa -out key.pem 2048
openssl req -new -x509 -key key.pem -out cert.pem -days 1095
cat key.pem cert.pem >> /etc/stunnel/stunnel.pem

4.configure Stunnel on VPS

vim /etc/stunnel/stunnel.conf

So overall the “stunnel.conf” file must contain the lines below:

client = no
[squid]
accept = 8888
connect = 127.0.0.1:3128
cert = /etc/stunnel/stunnel.pem

Note: The client = no part isn’t necessary, Stunnel by default is set to server mode.

Also, enable Stunnel automatic startup by configuring the “/etc/default/stunnel4” file

ENABLED=1

Finally, restart Stunnel for configuration to take effect, using this command:

/etc/init.d/stunnel4 restart

5.Install Squid Proxy

apt-get install squid3 -y

Configure Stunnel in Client

Using a SFTP client such as Filezilla, connect to your server and download the “stunnel.pem” file located in “/etc/stunnel/” directory to the client.

Install Stunnel on your choice of OS. Then go to the Stunnel folder and move the downloaded certificate “stunnel.pem” to Stunnel folder.

So “stunnel.conf” file in the client should look like this:

cert = stunnel.pem
client = yes
[squid]
accept = 127.0.0.1:8080
connect = [Server’s Public IP]:8888

Save and close the file and run “stunnel.exe”.

That’s it. Now when we want to connect to Squid proxy on our cloud server, we must configure our client to connect to 127.0.0.1:8080, and Stunnel automatically connects us through a secure tunnel to the service specified for that port.

+stunnel di rancang untuk menjadi wrapper SSL encryption antara client dan server. Bisa digunakan untuk menambahkan fungi SSL dalam sebuah sambungan. Pad dasarnya, stunnel membuat sebuah TCP port yang tidak secure menjadi sebuah port encrypted yang secure menggunakan package cryptography OpenSSL.
-The Stunnel program is designed to work as an SSL encryption wrapper between remote client and server. It can be used to add SSL functionality.
+Dalam bahasa yang lebih sederhana stunnel adalah proxy server SSL untuk berbagai proxy traffic yang tidak secure, agar menjadis secure. Sekedar gambaran, proxy yang normal seperti Squid biasanya tidak akan mem-proxy traffic SSL.
