ProxyBound v5.60
================
ProxyBound force any unix application to use a specific proxy and prevent it from leaking the original ip; Technically, ProxyBound is a UNIX program, that hooks network-related libc functions in dynamically linked programs via a preloaded DLL and redirects the connections through SOCKS4A/5 or HTTP proxies. This project is based on proxychain by [netcreature](https://sourceforge.net/u/netcreature/profile/), proxychains-ng by rofl0r, proxychains by haad and torsocks by dgoulet
Features:
=========
- Proxify applications (like mainstream proxychains)
- Works with tcp (like mainstream proxychains)
- No leaks over udp/icmp/etc... (INET & INET6)
- Unsupported protocols are blocked
- Support chrome/chromium/skype/similar
- Incompatible applications are terminated with a proper message
- Many additional settings over environment variable
- etc.
Used environment variable:
==========================
```
- PROXYBOUND_CONF_FILE: Path to config file (default ./proxybound.conf then /etc/proxybound.conf)
- PROXYBOUND_QUIET_MODE: Quiet mode (1 or 0, default 0)
- PROXYBOUND_SOCKS5_HOST: Specify unique socks 5 proxy to use (default not used)
- PROXYBOUND_SOCKS5_PORT: Socks 5 port (default not used)
- PROXYBOUND_FORCE_DNS: Force dns resolv requests through (1 or 0, default 1)
- PROXYBOUND_ALLOW_DNS: Allow direct dns, allow udp port 53 and 853 (1 or 0, default 0)
- PROXYBOUND_ALLOW_LEAKS: Allow/Block unproxyfied protocols "UDP/ICMP/ETC", blocked by default (1 or 0, default 0)
- PROXYBOUND_WORKING_INDICATOR: Create '/tmp/proxybound.tmp' when dll is working as intended (1 or 0, default 0)
```
How it works:
=============
Proxybound hook libc functions like connect(), dynamic loader facilities are used, namely dl_sym() and LD_PRELOAD thus dynamically linked programs are required.
Install:
========
```
./configure
make
[optional] sudo make install
```
If you dont install, you can use proxybound from the build directory like this: `./proxybound -f src/proxybound.conf telnet google.com 80`
Install debug version :
=======================
```
./configure
make debug
[optional] sudo make install
```

Limits :
========
- IPv6 is blocked and not supported (currently partially supported)
- Some applications are incompatible (they will be explicitly terminated 2 sec after startup, to avoid leaks)
Configuration:
==============
Proxybound config file in following order:
```
1) File listed in environment variable ${PROXYBOUND_CONF_FILE} or
provided as a -f argument to proxybound script or binary.
2) ./proxybound.conf
3) $(HOME)/.proxybound/proxybound.conf
4) /etc/proxybound.conf
```
Usage Example:
==============
In this example it will run telnet through proxy without using proxybound binary
```
$ export PROXYBOUND_QUIET_MODE="1"
$ export LD_PRELOAD=/usr/local/lib/libproxybound.so
$ export PROXYBOUND_CONF_FILE=/etc/proxybound.conf
$ telnet targethost.com
```
In this example it will run telnet through proxy(or chained proxies) specified by proxybound.conf
```
$ proxybound telnet targethost.com
```
In this example it will use different configuration file then proxybound.conf to connect to targethost2.com host.
```
$ proxybound -f /etc/proxybound-other.conf targethost2.com
```
In this example it will resolve targethost.com through proxy(or chained proxies) specified by proxybound.conf
```
$ proxyresolv targethost.com
```
