3proxy Combined proxy server may be used as
executable or service (supports installation and removal).
It uses config file to read it's configuration (see
3proxy.cfg.sample for details).
--install installs and starts proxy as Windows service
(config file should be located in the same directory)
--remove removes the service (should be stopped before via
'net stop 3proxy').
3proxy.exe is all-in-one, it doesn't require all others .exe
to work.
See 3proxy.cfg.sample for examples, see man 3proxy.cfg
proxy HTTP proxy server, binds to port 3128
ftppr FTP proxy server, binds to port 21
socks SOCKS 4/5 proxy server, binds to port 1080
ftppr FTP proxy server, please do not mess it with FTP over HTTP
proxy used in browsers
pop3p POP3 proxy server, binds to port 110. You must specify
POP3 username as username@target.host.ip[:port]
port is 110 by default.
Exmple: in Username configuration for you e-mail reader
set someuser@pop.somehost.ru, to obtains mail for someuser
from pop.somehost.ru via proxy.
smtpp SMTP proxy server, binds to port 25. You must specify
SMTP username as username@target.host.ip[:port]
port is 25 by default.
Exmple: in Username configuration for you e-mail reader
set someuser@mail.somehost.ru, to send mail as someuser
via mail.somehost.ru via proxy.
icqpr ICQ/AIM proxy. Maps some TCP port to TCP port of ICQ
server and performs packets translation. Example:
icqpr 5190 login.icq.com 5190
tcppm TCP port mapping. Maps some TCP port on local machine to
TCP port on remote host.
udppm UDP port mapping. Maps some UDP port on local machine to
UDP port on remote machine. Only one user simulationeously
can use UDP mapping, so it cann't be used for public service
in large networks. It's OK to use it to map to DNS server
in small network or to map Counter-Strike server for single
client (you can use few mappings on different ports for
different clients in last case).
mycrypt Program to obtain crypted password fro cleartext. Supports
both MD5/crypt and NT password.
mycrypt password
produces NT password
mycrypt salt password
produces MD5/crypt password with salt "salt".
dighosts Utility for building networks list from web page.


Run utility with --help option for command line reference.
