proxychains 使用指北

proxychains新的版本已经称为proxychains-ng由rofl0r托管在GitHub中维护,一般使用proxychains用于加速更新和下载国外的一些开源组件,比如yum和pip。proxychains使用十分简单,甚至都不必编译安装

3proxy简介

ProxyChains is a UNIX program, that hooks network-related libc functions in DYNAMICALLY LINKED programs via a preloaded DLL (dlsym(), LD_PRELOAD) and redirects the connections through SOCKS4a/5 or HTTP proxies. It supports TCP only (no UDP/ICMP etc).

The way it works is basically a HACK; so it is possible that it doesn’t work with your program, especially when it’s a script, or starts numerous processes like background daemons or uses dlopen() to load “modules” (bug in glibc dynlinker).

It should work with simple compiled (C/C++) dynamically linked programs though.

If your program doesn’t work with proxychains, consider using an iptables based solution instead; this is much more robust.

Supported Platforms: Linux, BSD, Mac.

proxychains 安装配置

# needs a working C compiler, preferably gcc
yum install gcc -y
./configure --prefix=/usr --sysconfdir=/etc
make
[optional] sudo make install
[optional] sudo make install-config (installs proxychains.conf)

# if you dont install, you can use proxychains from the build directory like this:
./proxychains4 -f src/proxychains.conf telnet google.com 80

# 一般编辑proxychains.conf添加socks5地址即可立即使用
vim /etc/proxychains.conf

[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
#socks4 127.0.0.1 9050
socks5 172.28.70.26 1080

proxychains.conf 配置文件

[root@centos7 ~]# cat /etc/proxychains.conf
# proxychains.conf VER 4.x
#
# HTTP, SOCKS4a, SOCKS5 tunneling proxifier with DNS.


# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
#dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#round_robin_chain
#
# Round Robin - Each connection will be done via chained proxies
# of chain_len length
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped).
# the start of the current proxy chain is the proxy after the last
# proxy in the previously invoked proxy chain.
# if the end of the proxy chain is reached while looking for proxies
# start at the beginning again.
# otherwise EINTR is returned to the app
# These semantics are not guaranteed in a multithreaded environment.
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see chain_len) from the list.
# this option is good to test your IDS :)

# Make sense only if random_chain or round_robin_chain
#chain_len = 2

# Quiet mode (no output from library)
#quiet_mode

# Proxy DNS requests - no leak for DNS data
proxy_dns 

# set the class A subnet number to use for the internal remote DNS mapping
# we use the reserved 224.x.x.x range by default,
# if the proxified app does a DNS request, we will return an IP from that range.
# on further accesses to this ip we will send the saved DNS name to the proxy.
# in case some control-freak app checks the returned ip, and denies to
# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
# of course you should make sure that the proxified app does not need
# *real* access to this subnet.
# i.e. dont use the same subnet then in the localnet section
#remote_dns_subnet 127
#remote_dns_subnet 10
remote_dns_subnet 224

# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000

### Examples for localnet exclusion
## localnet ranges will *not* use a proxy to connect.
## Exclude connections to 192.168.1.0/24 with port 80
# localnet 192.168.1.0:80/255.255.255.0

## Exclude connections to 192.168.100.0/24
# localnet 192.168.100.0/255.255.255.0

## Exclude connections to ANYwhere with port 80
# localnet 0.0.0.0:80/0.0.0.0

## RFC5735 Loopback address range
## if you enable this, you have to make sure remote_dns_subnet is not 127
## you'll need to enable it if you want to use an application that
## connects to localhost.
# localnet 127.0.0.0/255.0.0.0

## RFC1918 Private Address Ranges
# localnet 10.0.0.0/255.0.0.0
# localnet 172.16.0.0/255.240.0.0
# localnet 192.168.0.0/255.255.0.0

# ProxyList format
# type ip port [user pass]
# (values separated by 'tab' or 'blank')
#
# only numeric ipv4 addresses are valid
#
#
# Examples:
#
# socks5 192.168.67.78 1080 lamer secret
# http 192.168.89.3 8080 justu hidden
# socks4 192.168.1.49 1080
# http 192.168.39.93 8080
#
#
# proxy types: http, socks4, socks5
# ( auth types supported: "basic"-http "user/pass"-socks )
#
[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
#socks4 127.0.0.1 9050
