1/25    Question: when I log into soda and telnet to another machine, am I
        slowing down the processors?  In other words, do my commands go
        directly out to another ethernet port or do they pass through the
        CPU and then go out?  -tawei
        \_ ObLameAnswer: yes.
           \_ Would this be a serious answer? Inquiring minds want to know.
             \_ You are using mostly memory.
        \_ Let's see.  You're slowing down the CPU, you're taking up memory,
           and you're slowing down the network.  In addition, you're making
           your own, remote login session slower, and you're creating a
           dependency on soda.  All in all, it's a stupid thing to do.  Think
           for a moment about why the annex boxes might have an attention
           character, and why rsh and telnet have escape sequences.
         \_ I'll bite. What is the attention character on annex?
                      \_ Usually marked "break" on your kybd.  Sometimes you
                         have to do ctrl-break.

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?

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.

4/22    ok, here's a little networking puzzler. I haven't been able to access
        youtube for a couple weeks. Couldn't figure out why. Happened on all
        browsers. traceroute did weird stuff and then timed out. Finally I
        got so frustrated I setup firefox to ssh tunnel through soda.csua,
        which worked great. Then, I kill the ssh proc, quit FF, and now,
        I can access youtube just fine from any browser. wtf? any

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.

12/31   SOMEONE PLEASE FIX KEG!  Why does it keep crashing?
        \_ It's hard to tell. The risk of crashing seems to increase with
           disk activity, or so it seems, but debugging the kernel doesn't
           seem to yield much info. Email root for detailed info; I don't
           have a deep understanding of the problem --t

1/1     Is email still down?  My outgoing email seems to be not working.

12/4    A question to you old crufy alumni: So lately we've suggested
        VMs, and been asked why it's necessary. We've suggested top-of-the-line
        hardware and been told we don't need that much power. So I'd like to
        ask -- what exactly do you think the CSUA is supposed to _be_?
