2/9     What would be the most efficient way to check if a DNS server is
        still up (i.e. still resolving names)?  Does nslookup help?
        \_ nslookup http://blah.com your_dns_server.
                \- you need to define exactly what you want to test. i mean
                you can do anythign from a ping, to seeing if someone answers
                port 53 to doing a zone xfer. i would just do a zone xfer if
                allowed and see if it seems to be about the right size.
                [i am assuming you mean from a remote machine] --psb
                \_ The guy is having trouble with nslookup.  You want him to
                   do a zone xfer?  He'll be happy when nslookup returns.
        \_ To just make sure the daemon is running and getting your queries:
           "dig @ns1.domain.com version.bind chaos txt". *Then* start making
           sure it can answer queries on real domains.
        \_ ;; ANSWER SECTION:
           VERSION.BIND.           0S CHAOS TXT    "Surely you must be joking"
           Real admins use protection.
                \_ Any answer means the name server is working,  the actual
                   string reported is irrelevant in this case.  Real admins
                   know how to read what they're replying to.

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

11/4    Holy cow, I got a warning from my ISP that they were notified
        by BSA/baytsp.com that I was copying music/video/software.
        Do they do port scan or something? That's a first for me.
        \_ They hang out on P2P networks and track IP addresses.  -tom
           \_ I believe they are paid by content providers to perform this
              monitoring service, so you should only run this risk with content

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.

9/25    What's a nslookup equivalent to look up "set type=all"? I don't
        have nslookup anymore.
        \_ I think nslookup is deprecated and you're supposed to be using
           dig and host now.  Do you want the equiv 'host' acommand?
           \_ is it host -av <host>?

9/9     What should outbound mail server be when reading mail from soda

           \_ "The message could not be sent because connecting to SMTP
               server <DEAD>mail.csua.berkeley.edu<DEAD> failed. The server may

7/27    I have an actual technical question here. My MySQL DBA tells me
        that I can't expect a MySQL port to be able to run effectively
        on more than a two CPU box, he says that the extra CPUs will
        sit there unused. Is this true? I have a bunch of new quad core
        servers that I would like to use as Database machines. -ausman
