3/12    What's with http://berkeley.edu?  Up and down for the last hour...
        \_ From http://ucb.net.announct:

        From: lindahl@ack.Berkeley.EDU (ken lindahl)
        Subject: unexpected service outage today
        Newsgroups: http://ucb.net.announce
        Date: Wed, 12 Mar 2003 22:43:53 +0000 (UTC)
        Organization: Communication & Network Services

        the campus border router that connects to our ISP service failed
        around 1:30pm today. there is some evidence that the failure was
        preceeded (and perhaps caused) by an incoming packet flood; CNS
        is investigating this possibility.

        usually when this router fails, there is an automatic routing
        change that shifts the traffic to different border router in
        roughly a minute or so, so that the disruption is short-lived.
        for some reason, this did not happen gracefully in today's
        incident. traffic is moving across the backup router at this
        time, while we check the condition of the primary router. for
        reasons unknown, one of the interior interfaces on the primary
        router also failed in this incident; CNS has not seen this hap-
        pen before.

4/26    I see that soda has an ipv6 address but ipv6 traffic from this box
        doesn't actually work (ping6 <DEAD>ipv6.google.com<DEAD>, ping6 http://www.v6.facebook.com
        Is this expected to work?
        \_ Soda doesn't have a real IPv6 address.  The IPv6 addresses you see
           in ifconfig are just link-local addresses; any IPv6-capable machine
           will autogenerate these, whether or not it's connected to an IPv6

4/25    I have an Airport Express.  is there some way to let computer
        1 ping computer 2?  both computers are connected to wireless network
        successfully.  I can get to internet on both of them.  I just can't
        ping each other.  weird.  maybe they think that's a feature?
        \_ Sounds like your router is enforcing client isolation. If you can't
           change the setting on the router you're probably SOL.

3/12    I spent a whole day on this to no avail.  Using the Nortel Contivity
        client, logging into work suddenly stopped working (gets stuck on
        "banner text").  Rebooted laptop, checked with the VPN administrator,
        checked with the cable company, check the belkin router -- no changes
        anywhere, just stops working.  Laptop works fine from a different
        network, and a different machine on the same network can't get in

12/15   ausman, maybe this can help form your views on net neutrality:

11/11   Dumb question. My apartment has a bunch of inter-computer file
        exchange going on. Should I get a switch instead of a router to
        minimize traffic? Does it really make a difference? Let's say
        two computers exchanging info with each other are on the switch
        and the switch is connected to the router. The router will never
        know about the transfer between the two computers right?

9/29    I'm looking for a new wireless router / firewall, preferably
        something that supports 802.11n. Any recommendations?
        \_ Which 802.11n?
           \_ Draft 2.0 or whatever version is supported by the the
              MacBook and iMac.

6/16    What the minimum you can get away with paying for cable modem,
        in the South Bay?  Slowest available speed should be ok.
        Everythings seems to go to +$40/mo after teaser rates end.
        I need something faster than 56k modem but nothing really fast.
        Wondering if possible to keep under $20, since I'm out of town
        maybe 25% of the time.

5/31    I have a slow wireless router and slow fileserver on my network.
        Is there a video or media player (windows or unix) that is smart
        about caching content while playing it?  I would like to be able
        to hit play on a file from a file share, wait for it to catch
        up for a while because my connection is so slow, walk away for
        a while and come back and view my movie with no annoying skips. thanks.

3/13    I have an actual technical question for the motd. Where can I find
        the generic Cisco-style symbols for Visio 2003? For some reason,
        M$ pulled them from the recent edition and replaced them with
        their own crappy non-standard ones. I don't mean the icons at:
        http://www.cisco.com/en/US/products/prod_visio_icon_list.html
        I mean the generic circle with four arrows for a router, etc. -ausman
