<p>For information regarding configuring and building GNU/Linux
kernels, see

<p>Here's a screen shot of my Network Options Configuration:</p>
<blockquote>
  <p>&nbsp;<img border="0" src="images/netopts.jpg" width="609"

</blockquote>
<p>While not all of the options that I've selected are required, they
should be sufficient for most applications. Here's an excerpt from the
corresponding .config file (Note: If you are running a kernel older
than 2.4.17, be sure to select CONFIG_NETLINK and CONFIG_RTNETLINK):</p>
<blockquote> <font size="2">

<p>Note that I have built everything I need as modules. You can also
build
everything into your kernel but if you want to be able to deal with FTP
running
on a non-standard port then I recommend that you modularize FTP
Protocol
support.<br>
