tar a directory and send it to netcat

tar's directory and sends to netcat listening on port 10000

On the client end:

netcat [server ip] 10000 | tar xfvz -

This will send it over the network and extract it on the clients machine.

What others think

This is useful. It can also be done securely over ssh: tar cfz - /home/user | ssh 127.0.0.1 "tar xfz -" Over ssh is a little easier because you don't need to be on the other end to invoke netcat.

Nice ssh tip.

I like netcat for the fact that it's good for 'quick and dirty' solutions.

If you wanted to encrypt it:

tar cfz - [directory] | openssl bf -salt | netcat -l -p 10000

Then enter your encryption password.

Then on client do the reverse:

netcat [ip address] 10000 | openssl bf -d | tar xfz -

Then enter the password to decrypt.

Like you mentioned though, it does require someone on the other end to invoke it... maybe you could set a a remote shell over netcat to do this :)
