11/6    What's the easiest way to resolve a name to an IP on a machine
        that doesn't have bind. Is there a shell function?
        \_ ping
        \_ nslookup?
        \_ many os's have "host", but ping is probably most universal.
        \_ The machine doesn't have BIND installed?  Or doesn't use a
           nameserver?  Check /etc/hosts (hostname.hme0 or whatever interface
           on solaris.)  Some Windows boxes have a file called lmhosts or
           lmhosts.sam.  There are web-based nslookups available for boxes
           on the internet.  If your machine doesn't use a DNS server, ping
           won't return a remote machine's hostname, will it?  Otherwise just
           port scan it and see if it has any services running that might
           return a host name (http, smtp) when you telnet to that port. -John
                \_ Doesn't have BIND installed. It's a linux laptop.  ping
                   does just what I originally needed, but I'm going to try
                   to install nslookup and dig (both of which are part of
                   the BIND distribution) without installing named.
                   -- I just copied the two files "dig" and "nslookup" from
                   the /usr/bin of a linux box I trust, and copied them
                   into the /usr/bin/ of my laptop. That was easy.
        \_ vi /etc/hosts
        \_ on solaris/BSD, you can just "arp hostname" to get IP.
           Faster than ping.
           Don't have linux near me to see if behaves the same way.
           There are also web-sites that do nslookup for you as mentioned
           above, but only if it's an Internet IP.

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

11/7    Need help on http proxy. After I VPN to work, I'd like to tunnel
        all the traffic to my machine. How do I setup my machine (Linux)
        as a proxy server so that my home computers can route through it?
        I'm asking because the site we're testing on requires that we
        come from the same IP. If I use VPN, the server will reject me
        based on the fact that it's a different IP than my work Linux.

8/5     It looks like my company has started blocking HTTPS tunneling.
        I used to do this by tunneling SSH through the HTTP/HTTPS proxy
        server, but this seems to have stopped working. Does anyone know
        how the implementation of tunneling detection works, and whether
        there are widely available implementations? We run a bunch of MS
        stuff, so I imagine we're running an MS proxy server or something.

        We are deeply, deeply sorry to say that due to licensing constraints,
        we can no longer allow access to Pandora for most listeners located
        outside of the U.S. We will continue to work diligently to realize
        the vision of a truly global Pandora, but for the time being we are
        required to restrict its use. We are very sad to have to do this, but

10/31   A friend of mine said he's loving Microsoft again because Bill G
        is starting to donate all of his money to charity. He's boycotting
        Google, Yahoo, and other mega companies because they're too big and
        too power and thinks they're all becoming the old Microsoft, whereas
        Microsoft has recently done a lot of good things like investing in
        education and charity. He just paid for a copy of Microsoft Windows

2/18    My DSL modem's ip address is 192.168.0.1, my internal network
        behind my router is 10.0.0.x. Is there a way I can configure
        the router so I can access the DSL modem from my 10.0.0.x
        network directly without re-wiring? Static routes? I tried it
        but no much luck. I also tried changing my internal network to
        192.168.0.x, but still does not work. Thanks.

1/21    I am trying to setup a small network for my girlfriend's
        mom's company.  They just bought an accounting package
        which requires windows 2003 server.  And they want internet
        access from each computer.  How should the network be setuped?
        Would it be dumb to use static IP for each computer and a
        computer as internet gateway?

8/29    What's the difference between a hub, a switch and a router?  Thx.
        \_ AFAIK, probably be corrected by someone:
           hub: Allows communication on a LAN with bandwith shared amongs all
                the nodes on the hub and maxing out at the max line speed.
           switch: Allows communication on a LAN with bandwith greater than
                the max line speed (point to point)

6/2     I've been to many places and almost every place I go to have
        802.11b/g. However, almost all of them have protected access,
        which I presume they use because they don't want people stealing
        their bandwidth. So here is one idea I think will really
        revolutionize 802.11X... an option in the router that allows you to
        specify the percentage of unprotected bandwidth you are willing to

2/25    What is the smallest (physical and price) cisco router that can
        handle BGP?  It should be able to have more than 256 ram.
        \_ When you say ``handle BGP'', do you mean supports the bgp
           protocol or supports enough ram to keep a reasonable (what do you
           consider to be reasonable) number of routes in memory?  Do you want
           to be peering at PAIX, or do you just need a router to run the T1

1/13    I need help fixing someone's Win2K box.  Setup:  Win2K box -> D-Link
        router -> DSL modem.  The Win2K box cannot obtain a DHCP address
        (other computers can).  So, I assign a static IP, and set the default
        gateway and DNS server to be the D-Link router.  After this, the Win2K
        box can access web pages on the Internet as long as you specify the
        web site IP address directly -- but DNS doesn't work.  Computer used
