setting up an anonymous filetransfer service

I tried setting up a anonymous file transfer service using tor, and came to the following setup:

using these tools:

receiver

in torrc, add a hiddenservice, with this port:
```
HiddenServicePort 4242 127.0.0.1:4343
```
in rsyncd.conf
```
[ftp]
        path = /home/ftp
        comment = ftp export area
        read only = false
        use chroot = true
```
this sets up a rsync target named 'ftp', you have to make sure that rsync has permissions to write /home/ftp, and that the directory exists.

then start rsync as follows:

rsync --daemon --address 127.0.0.1 --port 4343

after tor has created the hiddenservice, find its hostname, by reading the [hiddenservicedir]/hostname file.

start socat, to forward requests to tor:

socat TCP4-LISTEN:4141,fork SOCKS4A:localhost:targethost.onion:4242,socksport=9050

i created some perl scripts to make it easy to do filetransfers via a tor hiddenservice.
needed:

windows xp ( it should not be very difficult to modify the scripts to work under a unix )
tor : http://tor.eff.org - version 0.1.2.14
activestate perl version >=5.7 http://www.activestate.com/Products/activeperl/

download http://nah6.com/~itsme/torx.zip
unzip it to some directory, for instance c:\torx
add c:\torx\bin to your search path.
set path=%path%;c:\torx\bin
then if you want to receive a file, type in the directory where you want to receive the file:
```
	perl torreceive.pl
```
this will print the hiddenservice name:
```
	listening on sad98ad08a0d8jui.onion:873
```
tell the person you want to send you a file anonymously to do this:
```
	perl torsend.pl somefile sad98ad08a0d8jui.onion:873
```
after doing 'torreceive' for the first time, it may take quite a while ( like 5 - 10 minutes ) before you can use the hidden service.
performance is not very high, like 10 kbyte/sec
aborted transfers can be restarted, it uses rsync to do the actual filetransfer.
