Out of curiosity...why run this as a service?

EDIT: I misread this and though it was only a client. Geez. If it's a server, then of course it should be a service.

How else would you expect an SSH server to run? As a desktop application?

[angersock]

Oh, I thought this was just a client.

So that you can ssh into a machine without manually starting sshd (or ssh-service) first.

Probably so that it can keep running even if no user account is logged in.

sshd on unix runs as a daemon, similar to a windows service.
