Slackware 13.37slackware-13.37
Mon Apr 25 13:37:00 UTC 2011
Slackware 13.37 x86_64 stable is released!
Thanks to everyone who pitched in on this release: the Slackware team,
the folks producing upstream code, and linuxquestions.org for providing
a great forum for collaboration and testing.
The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a
dual-sided
32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware
project by picking up a copy from store.slackware.com. We're taking
pre-orders now, and offer a discount if you sign up for a subscription.
As always, thanks to the Slackware community for testing, suggestions,
and feedback. :-)
Have fun!

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.
