Am rather disappointed that mbuffer isn’t shipped in CentOS 7. Easy enough to install, but seriously useful to have updated software in this day in age.

Anyhow, to use mbuffer for a long transfer where an outgoing connection was the only option, I finally found a situation where I wanted to use a fifo.

dmzhost$ mkfifo /tmp/tarfifo

lanhost$ ssh dmzhost "cat /tmp/tarfifo" | mbuffer -P90 -m512M | tar xf -

dmzhost$ tar cf - pub | mbuffer -P90 -m128M > /tmp/tarfifo

And there we have it.
