    Count how many sshd daemons are running. If more than one then there are
    external connections.
    ps -ax|grep sshd
    Since sshd forks a new version for each connection, you can kill and
    restart the original with impunity. It will not affect existing
    connections.
    However do not do killall sshd since that WILL kill existing connections.
    Rather if on a sysv type system do something like
    service sshd restart.

    Alternatively just send a
    kill -HUP
    to the main original daemon.
    That will tell it to reread the config file.
