  • Infuriating double MOTD

    I have just 2 servers that display the MOTD messages twice when either
    logging in or when ssh in. One is running 20.04 and the other 22.04, but
    I have others servers that do not do this.

    Also comparing confs for often posted "remedies" I have found in forums:
    /etc/pam.d/login, /etc/pam.d/sshd, and /etc/ssh/sshd_config and my /etc/ssh/sshd_config.d/local.conf are identical for the servers that
    double the MOTD to those that properly only display it once. PUZZLED

    I was able to replicate the *default* motd behavior on the two wayward
    servers by editing both the /etc/pam.d/login and /etc/pam.d/sshd by
    commented out the noupdate option as so:

    # This includes a dynamically generated part from /run/motd.dynamic
    # and a static (admin-editable) part from /etc/motd.
    session optional pam_motd.so motd=/run/motd.dynamic
    #session optional pam_motd.so noupdate

    The MOTD does update with each login, but now just displays once.
    However I am unable to determine why this is necessary, since the other
    servers require no such edit. If anyone can enlighten it would be welcomed.
