4/13    I have an SGI Indy that someone gave to me.  Is there a way (like
        in Linux) to boot up in single user mode and change the root
                \_ You probably mean "RedHat Linux". Sane distributions like
                   Debian will not just give you a free root shell when you
                   boot to single user mode.
                   \_ if you can pass the kernel the "single" parameter,
                      you ought to be able to pass it "init=/bin/sh"
                      instead.
                      \_ are you talking about a buffer overrun exploit here?
        password?  If not, how in the world do you install a new OS?
        There's no floppy drive and no CDROM drive.  The only thing that
        exists is a NIC but I thought you at least need a boot floppy for
        an FTP/NFS install. The machine has IRIX 6.4 btw.
        \_ No... if i remember correctly.. you don't need a boot floppy
           the hardware has a built in booter for doing nfs/ftp installs
           or you can get a cdrom for it :)  or i could be wrong..but i
           remember doing clean installs on boxes with no cdrom/floppy
        \_ Are you talking about changing the prom password?  It is
           possible to boot a miniroot and change the OS password.  You
           will need a cdrom or a network connection with a SGI (the
           cdroms, I believe, are in EFS format)

9/20    How do I change my shell? chsh says "Cannot change ID to root."
        \_ /usr/bin/chsh does not have the SUID permission set. Without
           being set, it does not successfully change a user's shell.
           Typical newbie sys admin (on soda)
           \_ Actually, it does: -rwsr-xr-x 1 root root 37552 Feb 15  2011 /usr/bin/chsh

9/24    How come changing my shell using ldapmodify (chsh doesn't work) doesn't
        work either? ldapsearch and getent show the new shell but I still get
        the old shell on login.
        \_ Scratch that, it magically took my new shell now. WTF?

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

2/9     Reminder: support for mail services has been deprecated for *several
        years*. Mail forwarding, specifically .forward mail forwarding, is
        officially supported and was never deprecated.
        \_ There is no .forward under ~root.  How do we mail root and how do
           we get responses?
           \_ root@csua.berkeley.edu is and always has been an alias.

9/12    We've restored CSUA NFS to something vaguely resembling normal
        functionality -- plus, with some luck, we should now have something
        vaguely resembling normal uptime, too!  Ping root@csua.org if you
        notice any problems.  --jordan

10/24  What's an easy way to see if say column 3 of a file matches a list of
       expressions in a file? Basically I want to combine "grep -f <file>"
       to store the patterns and awk's $3 ~ /(AAA|BBB|CCC)/ ... I realize
       I can do this with "egrep -f " and use regexp instead of strings, but
       was wondering if there was some magic way to do this.
       \_ UNIX has no magic. Make a shell script to produce the ask or egrep

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

           \_ An anachronism from a bygone era, when computers were hard to
