    What do you mean by this?

    A running sshd will fork() a child process to handle each connection
    that comes in. So you can connect as many times as you wish to a
    given server.

    On the client side, you can run as many instances of ssh as you need,
    one for each connection.

    An ssh tunnel set up between a client and a server will allow multiple
    connections. I currently run a tunnel from my workstation here at
    work, which is on a 10.* address behind a NAT, to my OpenBSD server
    at home. I'm tunneling port 8888, the Freenet web interface. When
    I point my web browser at 127.0.0.1:8888 I can establish multiple HTTP
    connections simultaneously.
