I have my SSH client configured to multiplex my sessions:
Host * ControlMaster auto ControlPath ~/.ssh/sockets/%r@%h-%p ControlPersist 600
I'm occasionally bumping into the default OpenSSH server side
MaxSessions limit of 10. The obvious answer is to increase
MaxSessions to a number significantly larger than I'd ever need.
Is there a reason to not just set it to 1000000? The default of 10 suggests this is some reason not to.
All I can come up with is perhaps past 10 or so, busy connections might be less efficient, but seeing as the harm would be limited to myself, I'm not sure this is the reason.
