12/5    We have a Sun E4000 that was upgraded to Solaris9.  At some point
        "soon" after the upgrade the machine began to semi-crash each day
        right after midnight.  You still had a console prompt, but it
        loses its nis binding/domainname, loses the default route [cant
        ping it from another subnet], and all the daemons stop listening.
        Any ideas?
        \_ do you have all the latest Sol9 cluster patches installed?
        \_ did you turn off power management?
           \_ What would that do?  What should I look at?
              does something magic happen at midnight?
           \_ This would be my first guess too.  Take a look in /etc/rc*.d
              for S85power or something like it.  if it's there, take it
              out and run /etc/init.d/power stop.  It could be trying to
              drop to a different init level on some odd schedule.  kill
              vold while you're at it.  grr... --scotsman
              \_ What's wrong with vold?
                 \_ Its a pos.
                    \_ It is but it won't kill his computer like this.
                        \_ Yeah, but you might as well turn it off and
                           dtlogin.
                           \_ gasp! you'd disable the world's best GUI?!
                    \_ never had problems with it but the dtlogin should
                       certainly go on a server.
        \_ You have a bad cron job that runs at 00:00?
           \_ There are some accounting-related cron jobs, but I
              cant think of a "normal userland process" that can
              cause all of this.
              \_ Maybe it can if it runs as root.  I don't know.
                 \_ root's cron jobs run as root and thus can fuck up the
                    entire system the same as root @ the keyboard.
                    \_ Let me put it another way: There was no new cronjob
                       added after the upgrade.  Maybe some file isnt being
                       found but something like that cant cause you to lose
                       your default route.  I'll try checking the run level
                       via who -r before rebooting it again.
        \_ We had something like this.  It was system accounting runnning
           the machine out of memory.  Sometimes it rebooted, sometimes
           it hung as described.  No memory == can't fork new proceses
           from inetd == no telnet, ftp, etc. -ax
           \_ but non-inetd stuff dies, like the domain binding and
              default route being lost.
           \_ ooh.. Good one. --scotsman
           \_ system accounting and /var/adm/messages are for weenies.  Real
              men read the pretty lights and feel the hum.

5/8     Hello everyone!  This is Josh Hawn, CSUA Tech VP for Spring 2012.
        About 2 weeks ago, someone brought to my attention that our script
        to periodically merge /etc/motd.public into /etc/motd wasn't
        running.  When I looked into it, the cron daemon was running, but
        there hadn't been any root activity in the log since April 7th.  I
        looked into it for a while, but got lost in other things I was

        years*. Mail forwarding, specifically .forward mail forwarding, is
        officially supported and was never deprecated.

6/5     In an effort to stabilize our services, we'll be rebuilding parts of
        the CSUA infrastructure over the course of this summer.  To give us
        some wiggle room, I've temporarily decreased soda's allocated RAM from
        8GB to 2GB.  If you need to run something that requires large amounts
        of memory, please send mail to root@csua.org and we'll try to
        accommodate your request.  --jordan

7/25    What's up with that moving bit pattern that Win7 displays when it
        boots up?  (It's the one that's like in the Apple II days when you
        use the graphics memory for code or data while it's still in HGR
        mode.)  Is there a way to disable that?  It slows things down a lot
        every time I reboot my Win7 VM on my office machine if I RDP to the
        machine via DSL.  Thanks in advance.
