1/09    There is both a wired and wireless network at work.  My laptop has
        a built in 802.11b Orinoco card and 10/100 ethernet adapter.  I have
        access (get IP addresses for) to both networks.  Question: How does
        my applications know which network to use?  How does my browser
        know how to go to Intranet sites via the wired (corporate) network?
        The wireless network is a DSL connection only.
           \_ I'm running both XP and RH8 on it.  ipconfig in XP lists
              the wireless connection first, then the local area connection,
              but I don't think that's necessarily the order for the routing.
              Is there a way to specify, say Opera to use the wireless
              interface, and IE to use the wired ntework?  (I haven't figured
              out how to use the wireless in RH8 yet; 'ifconfig eth1 up' gets
              it up, but I don't know how to get an IP ... it's a D-Link AP).
              -op
              \_ I'm almost certain that there's no easy way to have
                 browser-based connection choosing, unless you write a
                 wrapper script around your browsers that
                 a) records existing network options
                 b) changes them for that browser
                 c) removes the changes on browser quit.
                \_ You could probably do this with a local proxy.  I haven't
                   played with anything under XP, but I believe squid can be
                   told what interface to listen on.  If you gave it one of
                   your specific interfaces, I suppose it ought to work with
                   that one.  Then just point your browser at it.  As for the
                   IP, is the AP running in gateway or bridging mode?  I
                   assume you also have to run dhclient or something similar
                   on the interface (assuming you're using DHCP.)  Look at

8/9     Is there an automated way to change the IP of an XP machine? I have
        tests that need to get run on two separate sub-nets that now require
        me to physically go in and change the IP address of the test box.
        Cygwin is also installed if that helps any. Thanks
        \_ There are a few sort of hackey ways to do it:

4/19    After installing Logitech wireless mouse, my friend cannot connect from
        his PC to his wireless broadband router via a USB wireless network
        device.  It said that it cannot obtain IP address from the router.  Even
        uninstalling the Logitech wireless mouse doesn't help.  Do you know how
        to fix the wireless LAN problem, so that his PC can obtain IP address
        again?

8/29    What SMTP settings should I be enabling/disabling for soda?  I can
        receive csua mails over IMAP on my treo just fine, but I always
        get relay denied errors when sending outside http://csua.berkeley.edu.
        \_ Dunno the answer, but I have the same problem.  I ended up
           using Gmail's SMTP server.  The only thing is that you'll have

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

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

1/3     So I installed Debian (Sarge) on a home server for various reasons
        (including learning about Apache 2) and have a question:  how do I get
        all the useful information about my machine that I get in Windows with
        ipconfig /all?  And how do I turn DHCP on or off?  Set the host

4/7     What startup script or configuration file can be modified to set
        the ip address of a unix (actually Mac OS X) box to a particular

        \_ you can try running ifconfig or ipconfig *after* startup.

1/14    I am getting DSL for the first time.  The instruction from SBC says
        that I have to install stuff from their CD and leave the modem on for
        10 days for them to "maximize the speed."  I don't really want to
        install their custom browser and god-knows-what.  Can I just ignore
        their instructions and still get the highest speed possible?

9/22    I'm looking to expand my lan to include wireless.  The thing is, I
        like the linux-box router/firewall I already have set up.  Can I
        configure a wireless router station to run with a DHCP IP so I can
        continue to route everything through my hardwired linux-box?
        Many thanks.  --erikred

9/11    Hypothetical situation: Drive-By Filesharing  [format was here]
        I have a wireless access point.  I don't know how to stop people from
        connecting to me.  A P2P user connects to me to download files.  My
        ISP identifies my IP as downloading files.  Will RIAA sue me?  Is
        there an onus on all users who have wireless access points to secure
        their networks?  Can blame be shifted to makers of wireless access
