This tutorial is for Ubuntu & Squid3. Use AWS, Google cloud, Digital Ocean or any services with Ubuntu to follow this tutorial.
sudo apt-get update
sudo apt-get install squid3
sudo apt-get install apache2-utils
Choose a username/password. Example:
username: abc
password: 123
Type in console:
sudo touch /etc/squid/passwords
sudo chmod 777 /etc/squid/passwords
sudo htpasswd -c /etc/squid/passwords [USERNAME]
Replace [USERNAME] with your username, in this example: abc
.
You will be prompted for entering the password. Enter and confirm it. This example password: 123
.
/usr/lib/squid3/basic_ncsa_auth /etc/squid/passwords
After executing this line the console will look like its hung, there is a prompt without any text in it. Enter USERNAME PASSWORD
(replacing these with your specific username and password) and hit return. You should receive the response "OK".
If not, review the error message, your username/password might be incorrect. Its also possible basic_ncsa_auth is located on a different path (e.g. lib64).
Backup default config file:
sudo mv /etc/squid/squid.conf /etc/squid/squid.conf.original
Make a new configuration files
sudo vi /etc/squid/squid.conf
Enter this in the config file

: remove the forwarded_for http header which would expose your source to the destinationvia off
: remove more headers to avoid exposing the source.http_port 8888
: port 8888 is used for proxy. You can choose any port.
Save the file in vi with [esc]:wq
Start squid: sudo service squid start
To check service status: service squid status
Restart squid service
sudo service squid restart
or sudo systemctl restart squid.service
.
Use your proxy with your ip:port
. Example: 111.111.222.333:8888
and login with your user/pass.
You might need to create inbound firewall rule first before using the proxy.
For Google cloud: Firewall. Create an Ingress rule, Target Apply to all, IP range of 0.0.0.0/0
, allow TCP:8888, UDP:8888
for all traffic.
Not working in my case. I am on Debain vps of Vultr. Following the steps ended up with invalid url error while trying to access the proxy by typing ip:port in my browser
It was a bad request 400 error code...
