[aklug] Nerdy cross-machine file transfer methods.

I'd love to start a method on nerdy terminal based file transfer
methods. I have two to get started.

First is base64, tar, and a copy/paste buffer like seen in X11 or screen.

Source Machine (run command then copy output of base64 to a clipboard
of some sort):

--------
spencersr@undertow:~$ sudo tar cj /etc/default/ | base64
tar: Removing leading `/' from member names

Destination Machine (run command then paste into the terminal, finish
with ctrl-d):

--------
spencersr@lateralus:/tmp$ base64 -d | sudo tar xfvj - -C /tmp/
QlpoOTFBWSZTWSknZqgAIBN////wBEZe////v///+v////XIQEgAoIAGQAohiAhCEcAYYC77vvN9

Second is using screen and z-modem.

Start up screen on the local machine after making sure the lrzsz
package is installed on both machines. Once screen is started press
'ctrl-a' then ':' and type 'zmodem catch' to enable automatic zmodem
transfer detection.

Then secure shell to another box and run 'sz' on a file you want
transfered, the output should look a little like this:

--------
spencersr@undertow:~$ sz googleearth_5.0.11733.9347+0.5.4.1-1_amd64.deb
rz
:!!! rz -vv -b -E
Receiving: googleearth_5.0.11733.9347+0.5.4.1-1_amd64.deb.0
Bytes received: 25913236/25913236 BPS:8793256

Transfer complete
--------

I wanna know what the rest of you do. I often operate this way when I
need to do a root to root transfer when the root user is not
accessible via SSH due to security limits but I can get a root shell
on both machines.
