how to use socks proxy from wget

Warning : This post is my own note, you may believe on it or not.

Before continue read this post, I recommend you to read this post as preface.

Linux / BSD user usually familiar with shell, and wget is very usefull tool for download from shell. In this post I will explain how can wget use SOCKS proxy.

What is socks ?
From wikipedia “SOCKS is an Internet protocol that facilitates the routing of network packets between client–server applications via a proxy server. SOCKS performs at Layer 5 of the OSI model—the session layer (an intermediate layer between the presentation layer and the transport layer).”

Ok, this is the step.

1. Create the tunnel (from another tty or ttyv or terminal). I use ssh to create tunnel on localhost port 9999. You may create the tunnel with ping tunnel (ptunnel) or another tools.

lqman@development:~$ ssh -D 9999 -C lqman@180.247.xxx.xxx
lqman@180.247.xxx.xxx's password : xxxxxxxx

-D : bind on spesific port
-C : compress the connection [optional]

2. Check wheather the tunnel successfully created or not.

lqman@development:~$ sudo netstat -atupln | grep 9999
tcp 0 0 127.0.0.1:9999 0.0.0.0:* LISTEN 13680/ssh
tcp6 0 0 ::1:9999 :::* LISTEN 13680/ssh

if the LISTEN state appear, it means the tunnel has created successfully (on locahost port 9999) and ready to use.

3. install tsocks

lqman@development:~$ sudo aptitude install tsocks

4. configure tsocks, uncomment every line, except three lines below, and

lqman@development:~$ sudo vim /etc/tsocks.conf
server = 127.0.0.1
server_type = 5
server_port = 9999

5. Try to download with wget

lqman@development:~$ tsocks wget google.com
