        are not password protected 2) password protect your private keys

8/29    There was once a CSUA web page which runs an SSH client for logging
        on to soda.  Does that page still exist?  Can someone remind me of the
        URL please?  Thx.
        \_ what do you mean? instruction on how to ssh into soda?
           \_ No I think he means the ssh applet, which, iirc, was an applet
              that implemented an ssh v1 client.  I think this page went away

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

10/1    I am thinking of installing firefox on soda under my home directory.
        Will this make me a hozer?
        \_ Possibly. I wonder if we should have another VM for that...btw,
           I remember someone saying they're glad we're not on FreeBSD
           anymore, but last I checked, a bunch of our stuff is on FreeBSD,
           but our login server is not.

7/7     what happened to our web presence? http://www.csua.berkeley.edu
        not working
    \_ That would be because we've yet to set them up afaik. Steven *does* have
    a job after all. The idea is that we want a separate computer mounting the
    web directories, so that if an exploit compromises the webserver, the shell
    server (soda) itself will be insulated from the attack.

3/8     I'm reading about an old exploit where someone used a buffer overflow
        in a printer daemon to get "daemon privileges," which allowed them
        to use another exploit on the mail delivery program to get root.  I'm
        not sure what daemon privileges are.  Is there some set of priveleges
        that most daemons run on that is higher than user but lower than root?
        What are they?  I've never heard this before.

9/20    How do I change my shell? chsh says "Cannot change ID to root."

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.
