udpipe is a UDT data transfer device based off of the functionality of netcat.

TO MAKE

make -e os=XXX arch=YYY 

XXX: [LINUX(default), BSD, OSX]
YYY: [IA32(default), POWERPC, IA64, AMD64]

Dependencies:

OpenSSL (libssl and libcrypto)

udpipe has only been tested for Linux.

USAGE

udpipe follows the same model as netcat. The server side establishes a listener, and awaits an incoming connection. The client side connects to an established server or times out. Encryption is off by default. The encrypted option uses a multithreaded version of OpenSSL with aes-128.

Basic usage:

Server side: up [udtcat options] -l port

Client side: up [udtcat options] host port

udpipe Options:

 -l							start a server
 -n n_crypto_threads 		set number of encryption threads per send/recv thread to n_crypto_threads
 -p key				    	turn on encryption and specify key in-line
 -f path			        turn on encryption, path=path to key file
 -v							verbose
 -m packet_size             sets the max packet size (defaults to 1500)
 -t timeout					force udpipe to timeout if no data transfered
 -i local_ip                server only: specify which local ip to bind the server to 

Basic exmple (unencrypted)

Client side:

   up localhost 9000 < source/file

Server side:

   up -l 9000 > output/file

Basic exmple (encrypted)

Client side:

   up -n 4 -p key localhost 9000 < source/file

Server side:

   up -n 4 -f file/contains/key -l 9000 > output/file

This examples creates a connection to trasfer "source/file" to "output/file" over an encrypted stream on port 9000 which uses 4 threads to encrypt/decrypt each block with a specified key.
