Speed Up WAN File Transfer With Compression

If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...
