    On OmniOS r151014 I use ssh with rsa-keys to allow my storage systems to
    communicate and launch things like 'zfs receive'

    Periodically the connection fails with "ssh_exchange_identification:
    Connection closed by remote host"   When this happens about 1/2 the
    connection attempts will fail this way for about 10-20 minutes then thing
    return to normal.

    root at mir-dr-zfs01:/root# ssh -v mirpool02
    OpenSSH_6.6, OpenSSL 1.0.1p 9 Jul 2015
    debug1: Reading configuration data /etc/opt/csw/ssh/ssh_config
    debug1: Connecting to mirpool02 [10.28.125.130] port 22.
    debug1: Connection established.
    debug1: permanently_set_uid: 0/0

    debug1: identity file /root/.ssh/id_rsa-cert type -1

    ssh_exchange_identification: Connection closed by remote host
    root at mir-dr-zfs01:/root# echo $?
    255

    I've not been able to get logs out of the SunSSH server, turning things on
    in /etc/syslog.conf, doesn't seem to work.   What am I am missing in trying
    to get more information out of the ssh server?

    I used OpenSSH client from OpenCSW, using the SunSSH client and the problem
    happens nearly twice as often.

    Any suggestions on how to make these connections robust?

    Thanks!
