The Kindle and the XS

The Kindle 3’s default networking stack doesn’t support the XS’s network scheme, so DHCP won’t work.  However, we can manually connect with a static IP.  Tested and verified on a Kindle 3 (wifi and 3G) running Firmware 3.1.

I was a bit stymied at first, as I could see the DHCP offer in /var/log/messages, but some googling around told me this is a common issue.

From Menu -> Settings, look at the Device Info to get the Kindle’s MAC address.  Mine is 28:ef:01:32:bc:88

Edit this file:


On XS 0.6, the range is outside of DHCP, so this step really isn’t necessary.  However, I have other devices on this range and I like to keep notes about what’s where.  So, I’m going to go ahead and specify the kindle’s static IP in the DHCP configuration file.

The hostname doesn’t have to be kindle, but try to be descriptive.  Simply put this line at the bottom of the dhcpd.conf.1 file, making sure to supply the correct MAC address.  And make sure the static IP you specify isn’t being used by anything else.

host kindle {hardware ethernet 28:ef:01:32:bc:88; fixed-address;}

Restart dhcpd after the edit.

service dhcpd restart

On the Kindle, try to connect to the XS’s wifi AP.  After a minute or so it’ll fail to connect and then give you the option to manually configure the network.  Here’s what I put:

IP Address
Subnet Mask

I’m using OpenDNS, but you can use your ISPs or (probably, I haven’t tested) the XS’s  The two opendns IPs are:

Try to connect again and it should work.  The Kindle doesn’t respond to ping, but you can verify connectivity server side by getting a response from

nmap -sS

It should look like:

[root@schoolserver ~]# nmap -sS

Starting Nmap 4.53 ( ) at 2011-03-26 19:36 CDT
All 1714 scanned ports on are filtered
MAC Address: 28:EF:01:32:BC:88 (Unknown)

Nmap done: 1 IP address (1 host up) scanned in 63.603 seconds

When you go to http://schoolserver from the Kindle, this is what the user agent looks like in the Apache log. – – [22/Mar/2011:16:36:13 -0500] “GET / HTTP/1.0” 200 1850 “-” “Mozilla/5.0 (Linux; U; en-US) AppleWebKit/528.5+ (KHTML, like Gecko, Safari/528.5+) Version/4.0 Kindle/3.0 (screen 600×800; rotate)”
