How to set up SOCKS5 proxy in Ubuntu?

How to setup SOCKS5 proxy server?

I am trying to setup socks5 proxy on my linux machine, and I need to forward internet connection on the basis of socks5 protocol.

Can any one help in this regard? Is there any specific steps or procedure need to follow to create proxy server? Thanks for your precious help! I have used OpenProxyD to set up a custom socks proxy before: It's simple, and it just requires you set up the proxy for the DNS entries you want to proxy and then you just point all your browsers at the proxy IP and they will connect. It's just an old version but it's quite good. There's a list of proxies available at the homepage which should help.

EDIT. The OP had some additional constraints and needed this to be done on a Mac. There is this neat tool called "NetSocks" that can be used to setup the proxy. It is free and is open source and it's written in Python so this makes installing it pretty easy. Here are the instructions on how to install it:
For Linux, it also has an OSX package (from the above link) and you can use the following commands to setup the proxy on OSX Mavericks. You may need to tweak the hostname to something like "localhost". You can also have it run as a daemon by default and it will work fine as a socks5 proxy, just check the documentation on NetSocks to see how to do that.

Brew install netmink # Install homebrew with OS X package manager. Brew cask install netsocks # Install the NetSocks package from Brew. Brew edit netsocks # Edit the file and modify the hosts entry to your host.

How to configure SOCKS proxy in Linux?

SOCKS is a connection-oriented protocol used for communication between the application and some remote web server.

SOCKS supports tunneling TCP streams from an application onto an SOCKS 5 server, and back from an SOCKS 5 server to another application. The standard provides limited configuration options, which are typically used by those wishing to implement dynamic NAT traversal or to make SOCKS proxies less visible to local network administrators. This article presents the details of how to configure Linux as a SOCKS proxy server for your LAN, with full options for configuration and access control.

If you are interested in tunneling the Internet traffic of one application to another application (usually to another computer), you need a SOCKS proxy server on your LAN (Local Area Network). SOCKS 5 is a connection-oriented protocol for encapsulating TCP streams and was defined in RFC 1928. It may be used for both data channel setup and data channel tear down, but this document focuses on data channel setup.

The main concept behind SOCKS is a protocol tunnel used for encapsulation. An application establishes a SOCKS connection with a SOCKS proxy server. This tunnel makes it possible to route the Internet traffic of an application to another application on a different computer, without the users being aware of the SOCKS proxy. In other words, the local proxy server can act as a transparent tunnel between the source and destination applications.

Most clients use SOCKS to connect to the remote webservers. But in this example we will configure the server to act as a SOCKS proxy to tunnel Internet traffic from an Android client to our desktop PC. You will not need to use any mobile or desktop application for this experiment. All the traffic is simply routed through the server, which acts as a SOCKS 5 proxy. We only need the server application on the desktop.

In this tutorial, we are going to use a Linux OS to act as a SOCKS 5 proxy, which will be used to secure data from one application to another. The idea here is that one app should have an active session, and you can easily route the Internet traffic through the proxy. If you want to protect certain Internet applications, then you need to create a VPN tunnel for all the applications.

ADVERTISEMENTS.

How to setup SOCKS5 proxy server in Ubuntu? Set up SOCKS5 proxy on Ubuntu using Squid is fairly simple. This post shows how to set up SOCKS5 proxy on Ubuntu or Linux desktop system. It covers using SSH and Tor networks as SOCKS5 proxy method. You can use any supported SOCKS5 proxy server method instead of SSH or Tor. We will see How to configure SOCKS5 proxy in Ubuntu.I do not recommend that you expose your computer/Linux router/mobile device to the public internet by using a SOCKS5 proxy. If you want to bypass firewall, proxy, parental control or censorship in your country, then you need to use an SOCKS5 proxy server.

SSH and SOCKS5 proxies are one of the most common SOCKS5 proxy setup methods used on the Internet. We can use SSH, DNS over HTTPS (DoH), Network Information Service (NIS) server, ProxyDNS, Tor and etc. I highly recommend use VPN instead.

SOCKS5 proxy is basically a TCP or UDP connection that sends data from the client to a SOCKS proxy server. The SOCKS proxy then relays that data to the destination server. In other words SOCKS5 protocol provides tunnelling, forwarding and relaying for your TCP or UDP traffic via internet.

Use Tor or SOCKS5 proxy over SSH, DNS or TOR relay? We should use SOCKS5 proxy over a secure tunnel such as SOCKS5 over SSH, SOCKS5 over DNS or SOCKS5 proxy over Tor for online traffic. I do not recommend a SOCKS proxy on mobile, phone, tablet or laptop.

We might be blocked by ISP or government if we use SOCKS proxy servers. There are many ISPs and countries that block SOCKS5 proxy or Tor proxy or VPN protocols such as OpenVPN, PPTP or L2TP/IPSec.

How to install a SOCKS5 proxy on Ubuntu, Linux? I highly recommend use a SOCKS5 proxy instead of Tor browser add-on. Install SOCKS5 proxy - Prerequisites. Make sure that your firewall permits remote connections from the internet via SOCKS5 proxy server.
