I have a network of 100 machines, all with ubuntu Linux.
Is there a limit to the number of machines that can connect to one single machine (at the same time)?
For example, can I have 99 of my machines maintain continuous ssh connection to the 100th machine? Can I have every one of my machines (every one of the 100) maintain a continuous ssh connection to all other 99 machines?
How much memory does each such a connection take?
