Slackware 13.0 x86_64 is released as stable! Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits. The ISOs are off to the replicator. This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com. Please consider
picking up a copy to help support the project. Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy! -P.

The network can be as +simple as a few computers connected in your home or office, or as complicated as a large +university network or even the entire Internet. When your computer is part of a network, +you have access to those systems either directly or through services like mail and the +web.</p> + +<p>There are a variety of networking programs that you can use. Some are handy for +performing diagnostics to see if everything is working properly. Others (like mail +readers and web browsers) are useful for getting your work done and staying in contact +with other people.</p> + +<div class="SECT1"> +<h1 class="SECT1"><a id="BASIC-NETWORK-COMMANDS-PING" +name="BASIC-NETWORK-COMMANDS-PING">13.1 <tt class="COMMAND">ping</tt></a></h1> + +<p><tt class="COMMAND">ping</tt>(8) sends an ICMP <var class="LITERAL">ECHO_REQUEST</var> +packet to the specified host. If the host responds, you get an ICMP packet back. Sound +strange? Well, you can “ping” an IP address to see if a machine is alive. If +there is no response, you know something is wrong. Here is an example conversation +between two Linux users:</p> + +<a id="AEN4428" name="AEN4428"></a> +<blockquote class="BLOCKQUOTE"> +<p class="LITERALLAYOUT"><span class="emphasis"><i class="EMPHASIS">User +A</i></span>: Loki's down again.<br /> +<span class="emphasis"><i class="EMPHASIS">User +B</i></span>: Are you sure?<br /> +<span class="emphasis"><i class="EMPHASIS">User +A</i></span>: Yeah, I tried pinging it, but there's no response.</p> +</blockquote> + +<p>It's instances like these that make <tt class="COMMAND">ping</tt> a very useful +day-to-day command. It provides a very quick way to see if a machine is up and connected +to the network. The basic syntax is:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ping www.slackware.com</kbd> +</pre> +</td> +</tr> +</table> + +<p>There are, of course, several options that can be specified.
