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
        either, so it's the home network.  Tried rebooting router, checking
        all the settings in the router, outgoing connections (VPN uses UDP
        port 500) not blocked.  Tried putting the machine in the DMZ, didn't
        work either.  Just will not work.  Did I miss anything? -eric
        \_ What happens if you try using the cable connection directly
           (i.e., without the router)? If that works, maybe your router is
           dying.
            \_ Forgot to mention that EVERYTHING works except using the VPN.
               \_ Well clearly, something somewhere has changed. The admins
                  aren't always aware of changes either; you'd probably be
                  giving them too much credit if you assumed they were
                  authoritative. Also, Nortel VPN (among others) uses
                  non-TCP/UDP packets, so likely these are getting blocked or
                  mishandled somewhere. It would not be immediately obvious
                  since the majority of traffic is either TCP or UDP.

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.

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

11/1    I'm moving from a home in Fremont to another home within the same ZIP
        code in Fremont, and AT&T customer service says I cannot transfer my
        DSL service because DSL is not available at my new home.  Is that BS?
        Are they just trying to push me to subscribe to their more expensive
        U-verse service?  I'm not asking for any lightening-speed connection.
