[Bug 805423] Re: pam_motd needs a module option to disable in-line dynamic updates

[Andreas Hasenack]

Do you have any reason to believe "who" would stall? Do you have network
users, stored in ldap or nis? Doesn't look like it, but it doesn't hurt
to ask.

sysinfo uses this to get the logged in users:

def get_logged_in_users():
    result = getProcessOutputAndValue("who", ["-q"], env=os.environ)

So basically it calls "who -q".

What are all the scripts you have in /etc/update-motd.d/*?

  3) Login on systems with high load/a lot of io wait via ssh should
  still be possible.

  4) On servers with high load or a lot of io wait login times out,
  because pam_motd does io intensive calculations. This hurts even more
  when using nagios check_by_ssh. There should be a way to use a cron
  job again (like update-motd did). Logging into a system is more
  important than motd.
