10/17   I'm using linux with a broadband router for the first time. The linux
        machine gets all the proper info through DHCP, but DNS doesn't work.
        How does the DHCP client set the name servers? By writing directly to
        /etc/resolv.conf or something? I'm just manually inserting entries in
        there to get it working for now.
        \_ man dhcpclient
           \_ if you had a clue, you'd at least know it's man dhclient. and
              have you actually tried reading that page?
              \_ real men use static ips.
        \_ Actually you want to look at dhclient.conf(5).  Normally, you
           should be able to have an empty config file--your client gets its
           DNS servers by DHCP, just like its default gateway, and puts them
           in resolv.conf.  If this doesn't work, you can override a lot
           of things in dhclient.conf, such as 'prepend domain-name-servers
           <IP>; which will put <IP> before whatever you get from the dhcp
           server every time.  -John
           \_ the problem is just that it's not doing any of these things.
              it is getting the proper info since it shows up in the leases
              file, but it's not writing resolv.conf. i'm using an empty
              dhclient.conf.
              \_ Try a new OS.  It's obviously a linux problem that no one
                 here is qualified to answer.
                 \_ o-kay. at least you, anyway.

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

12/6    I'm running 64bit VMWare 2.0 in debian lenny/testing.  I have 18
        guest VMs running, all in bridged mode.  Works great.  the 19th VM
        I turn on has no working network.  No net, dhcp/tftp doesn't work,
        nothing.  Can anyone think of a network or kernel setting in Linux
        that would prevent any more VMs from getting network access?

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?

10/15   Has anyone else used dnsmasq for DHCP and PXE booting?  Have you found
        a way to specify the 'next-server' option with dnsmasq?
        conventional DHCP daemons let me specify 'next-server', I can't
        figure out how to do it with dnsmasq.  Thanks - danh
