Lanfile is a nice program for sending and receiving files with many features: MD5 hash, multiplatform, large file support, listen and connect mode for using it when is not possible to receive connections (NAT/router), file resuming, compression through LZO, password (APOP-like), execution of commands when each file is received, allowed hosts, stdin, encryption, xor and others.

The most interesting feature of the tool is probably the possibility of accepting or doing connections, so it can be used also on computers behind firewalls or routers. Its just enough that one of the two computers is able to accept connections.

Lanfile Features:
1. MD5 hash comparison, so the received files are ever corrects
2. easy to use: interactive mode and examples
3. multiplatform, tested on Linux and Windows and on both little and big endian architectures
4. large file support, files bigger than 2 gigabytes
5. simultaneous uploads/downloads
6. recursion, so is possible to send entire folders
7. works behind firewalls/NAT/routers in both the directions
8. file resuming
9. password support (like APOP)
10. compression (LZO)
11. can be used as file server for both sending and receiving files
12. possibility to execute a command for each file that has been received
13. options for automatic overwriting and file skipping
14. list of allowed IP which can connect to Lanfile

Usage: lanfile.exe [options] <host> [file/dir1] ... [file/dirN]

Options:
-p PORT server or local port to use (6969)
-b IP IP of the interface to bind (any interface)
-d DIR incoming folder (current: F:\SoftSea.com)
-o automatic files overwriting
-k automatically skip all the existing files
-r automatic file resuming
-m MD5 hash verification only, no files transfer
-f fast mode useful with many files, it automatically activates -o !
-1 one full incoming transfer/client only and then exit
-a I1,In list of IPs and hostnames which are allowed to connect to you when you are in listening mode, use a comma for separating the hosts
-x "EXE" launch a command for each file received. EXE is the command-line, use the #FILE pattern which will be substituited with each file
-w PASS set a password valid only in listening mode, in connect mode this password will be used when connected to a passworded server
-z enable compression
-c rc4 encryption using the filename as key
-C simple XOR obfuscation
-l no limit size, use this option with devices and special files
-q quiet output, no file percentage
-i interactive mode, you must simply answer to some questions
-e some practical examples of how to use this tool

Use the <host> 0 for the listening mode (accept incoming connections) If you specify files or folders they will be sent to the other host, specify no files for enabling the recvfile mode for receiving files. You can also use wildcards (*file*) if your OS supports them or - for stdin.
