Transfer files with ethernet cable

How To Transfere files any Ethernet cable in GNU/Linux

Imagine we have two hosts, A and B, we want to send a file or more from A to B

it's actually easy as cake and faster than using usb

• plug the cable to both hosts

• make a subnet mask and give each host an IP address in the subnet

  in host A:

  ip address add 10.0.0.10/24 dev <device_name>

  in host B:

  ip address add 10.0.0.20/24 dev <device_name>

  you can choose whatever IPs you like but make sure they are in the same subnet.

  to get the device name just run ip addr show

• connect B to A while A is listening to a port and sending the files into it

  in host A:

  tar cz /path/to/send | nc -q <timeout_seconds> -l -p <port>

  in host B:

  nc -w <wait_seconds> <ip_given_to_A> <port> | tar xz --directory /path/to/save

And thats it after the transfere is done the connection will close, because we specified the -q option.

Avoid typing to stdin in both terminal while transfering, if you are using a terminal emulator you are free to open another terminal and do whatever you want while the files are being transfered.
