This trend doesn't appear to -be slowing down. Unfortunately, wireless networking isn't yet as strongly supported in -Linux as traditional wired networking.</p> - -<p>There are three basic steps to configuring an 802.11 wireless Ethernet card:</p> - -<ol type="1"> -<li> -<p>Hardware support for the wireless card</p> -</li> - -<li> -<p>Configure the card to connect to a wireless access point</p> -</li> - -<li> -<p>Configure the network</p> -</li> -</ol> - -<div class="SECT2"> -<h2 class="SECT2"><a id="AEN2033" name="AEN2033">5.5.1 Hardware Support</a></h2> - -<p>Hardware support for a wireless card is provided through the kernel, either with a -module or built in to the kernel. Generally, most newer Ethernet cards are provided -through kernel modules, so you'll want to determine the appropriate kernel module and -load it through <tt class="FILENAME">/etc/rc.d/rc.modules</tt>. <tt -class="COMMAND">netconfig</tt> may not detect your wireless card, so you'll probably need -to determine the card yourself. See <a -href="http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/" -target="_top">http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/</a> for more -information on kernel drivers for various wireless cards.</p> -</div> - -<div class="SECT2"> -<h2 class="SECT2"><a id="AEN2044" name="AEN2044">5.5.2 Configure the Wireless -Settings</a></h2> - -<p>The vast majority of this work is done by <tt class="COMMAND">iwconfig</tt>, so as -always read the man page for <tt class="COMMAND">iwconfig</tt> if you need more -information.</p> - -<p>First, you'll want to configure your wireless access point. Wireless access points -vary quite a bit in their terminology, and how to configure them, so you may need to -adjust a bit to accommodate your hardware. In general, you'll need at least the following -information:</p> - -<ul> -<li> -<p>The domain ID, or name of the network (called the ESSID by <tt -class="COMMAND">iwconfig</tt>)</p> -</li> - -<li> -<p>The channel the WAP uses</p> -</li> - -<li> -<p>The encryption settings, including any keys used (preferably in hexadecimal)</p> -</li> -</ul> - -<div class="WARNING"> -<table class="WARNING" width="100%" border="0"> -<tr> -<td width="25" align="CENTER" valign="TOP"><img src="./imagelib/admon/warning.png" -hspace="5" alt="Warning" /></td> -<td align="LEFT" valign="TOP"> -<p>A NOTE ABOUT WEP. WEP is quit flawed, but it's much better than nothing. If you wish a -greater degree of security on your wireless network, you should investigate VPNs or -IPSec, both of which are beyond the scope of this document. You might also configure your -WAP not to advertise its domain ID/ ESSID. A thorough discussion of wireless policy is -beyond the scope of this section, but a quick Google search will turn up more than you -ever wanted to know.</p> -</td> -</tr> -</table> -</div> - -<p>Once you've gathered the above information, and assuming you've used <tt -class="COMMAND">modprobe</tt> to load the appropriate kernel driver, you can edit <tt -class="FILENAME">rc.wireless.conf</tt> and add your settings. The <tt -class="FILENAME">rc.wireless.conf</tt> file is a bit untidy. The least effort is to -modify the generic section with your ESSID and KEY, and CHANNEL if required by your card. -(Try not setting CHANNEL, and if it works, great; if not, set the CHANNEL as -appropriate.) If you're daring, you can modify the file so that only the necessary -variables are set. The variable names in <tt class="FILENAME">rc.wireless.conf</tt> -correspond to the <tt class="COMMAND">iwconfig</tt> parameters, and are read by <tt -class="FILENAME">rc.wireless</tt> and used in the appropriate <tt -class="COMMAND">iwconfig</tt> commands.</p> - -<p>If you have your key in hexadecimal, that's ideal, since you can be fairly confident -that your WAP and <tt class="COMMAND">iwconfig</tt> will agree on the key. If you only -have a string, you can't be sure how your WAP will translate that into a hexadecimal key, -so some guesswork may be needed (or get your WAP's key in hex).</p> - -<p>Once you've modified <tt class="FILENAME">rc.wireless.conf</tt>, run <tt -class="FILENAME">rc.wireless</tt> as <tt class="USERNAME">root</tt>, then run <tt -class="FILENAME">rc.inet1</tt>, again as <tt class="USERNAME">root</tt>. You can test -your wireless networking with standard testing tools such as <tt -class="COMMAND">ping</tt>, along with <tt class="COMMAND">iwconfig</tt>. If you have a -wired interface you may wish to use <tt class="COMMAND">ifconfig</tt> to turn those -interfaces off while you test your wireless networking to ensure there's no interference. -You may also want to test your changes through a reboot.</p> - -<p>Now that you've seen how to edit <tt class="FILENAME">/etc/rc.d/rc.wireless</tt> for -you default network, let's take a closer look at iwconfig and see how it all works. This -will teach you the quick and dirty way of setting up wifi for those times when you find -yourself at an Internet cafe, coffee shop, or any other wifi hot spot and wish to get -online.</p> - -<p>The first step is to tell your wireless NIC what network to join. Make sure you -replace “<tt class="FILENAME">eth0</tt>” with whatever network interface your -wireless card uses and change “<var class="REPLACEABLE">mynetwork</var>” to -the essid you wish to use. Yes, we know you're smarter than that. Next you'll have to -specify the encryption key (if any) used on your wireless network. Finally specify the -channel to use (if needed).</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">iwconfig eth0 essid "<var -class="REPLACEABLE">mynetwork</var>"</kbd> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">iwconfig eth0 key <var -class="REPLACEABLE">XXXXXXXXXXXXXXXXXXXXXXXXXXX</var></kbd> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">iwconfig eth0 channel n</kbd> -</pre> -</td> -</tr> -</table> - -<p>That should be all on the wireless end of things.</p> -</div> - -<div class="SECT2"> -<h2 class="SECT2"><a id="AEN2101" name="AEN2101">5.5.3 Configure the Network</a></h2> - -<p>This is done in the exact same way as wired networks.
