How To Install Paros Proxy In Ubuntu
In this tutorial, we will learn how to install and configure the squid proxy and caching server on Ubuntu Linux. The term proxy is generally combined with two different terms, one is forward proxy and the other is reverse proxy.
Jul 17, 2011 - I'm not sure if this is in the right categories but anyway. I am trying to get paros proxy running for a security class that i am taking. Feb 12, 2018 - The OWASP Zed Attack Proxy (ZAP) is one of the world's most popular free security tools and is actively maintained by hundreds of.
Most of the time when we talk about proxy it generally refers to forward proxy. A forward proxy server works on behalf of clients and hide the client IP address from the internet.
A reverse proxy server is the exact opposite of a forward proxy server. Reverse proxy server is worked behalf of the server and protects servers from the outside world.
Today we are going to configure forward proxy on Ubuntu using Squid3. To install and configure Squid on Ubuntu Server 16.04, we have to take the following steps:
- Install the squid3 package.
- Configure web caching.
- Configure Access Control List(ACL).
We can easily install Squid as usual from the Ubuntu software repositories. Open the command line and install squid3 package.
Open the /etc/squid/squid.conf file:
Uncomment the cache_dir directive to add a disk cache directory:
Restart the Ubuntu squid server:
Squid server by default listens to TCP port 3128, So Make sure that you have allowed the TCP port 3128 on your firewall.
The default cache size is 100MB. To change cache size edit the cache_dir directive. The following example sets squid cache size to 500MB:
Control Access to the Ubuntu Proxy server with Access Control List (ACL)
You can limit users’ ability to browse the Internet with access control lists (ACLs). by default, the Ubuntu Squid.conf file is configured with ACL lines that will deny access to everything except the localhost. So now we need to set the list of IP addresses allowed to use squid.
Following example will allow IP address 192.168.1.10 to connect to the internet through the proxy server.
Add the following line at the bottom of the acl section of /etc/squid/squid.conf (under the TAG: acl):
Then, add the following line at the top of the http_access section of the /etc/squid/squid.conf (under the TAG: http_access):
Finally, Restart the squid server:
In the above example, we added IP address 192.168.1.10 to the ACL group called allow_clients.
Then, we enabled http access to the allow_clients group.
Now the client with IP address 192.168.1.10 can browse the internet through the Ubuntu proxy server.
You can add multiple IPs to the ACL group as follows:
Manage Squid Proxy Server
You can manage squid on Ubuntu with systemctl command. To view server status, Type:
To start the squid service, Type:
Set squid server to start at system reboot (default):
Run netstat command to make sure that the squid is listening on port 3128:
Summary
In this tutorial we learned squid proxy server configuration in Ubuntu step by step.
- We start by installing the Squid3 package on Ubuntu.
- Once the squid3 is installed, we edit the configuration file to enable web caching by uncommenting the cache_dir directive.
- Then, we learned how to control access to the proxy server with Access Control List (ACL).
I've got an Ubuntu 11.10 system connected via a proxy to the internet, and I would like to install packages via apt-get. When I try to do that I get this error message:
Any ideas?

This method worked for me.....just have a try...
check the file /etc/apt/apt.conf
Paros Proxy Server
The contents were,
This was the reason why you could reach proxy but couldn't get past it, since there is no username password information. So just put that info into it..
save the file and you are done...
BROTIP: More better add these lines in another file, /etc/apt/apt.conf.d/80proxy
. This will ensure that after a version upgrade changes won't be lost.
To configure a proxy temporary, set the http_proxy
environment variable. If the proxy is proxy.example.com
on port 8080
and you need to authenticate with username user
and password pass
, run:
To set such a proxy permanently, create /etc/apt/apt.conf.d/30proxy
containing:
The changes are immediately visible the next time you run apt.
An alternative is to use Synaptics Package Manager, setting in its Preferences the proxy to which you want to connect. You can find the configuration using this path:Settings -> Preferences -> Network
