Useful to get network access to a machine behind shared IP NAT. Assumes you have an accessible jump host and physical console or drac/ilo/lom etc access to run the command.
Run the command on the host behind NAT then ssh connect to your jump host on port 2222. That connection to the jump host will be forwarded to the hidden machine.
Note: Some older versions of ssh do not acknowledge the bind address (0.0.0.0 in the example) and will only listen on the loopback address.
Useful when you have multiple files or binary files that you need to transfer to a different host and scp or the like is unavailable.
To unpack on the destination host copy paste output using the opposite order:
openssl enc -d -base64 | gunzip | tar -x
Terminate openssl input using ^d
Note: gzip is outside of tar because using -z in tar produces lots of extra padding.
