<title>system moodss module</title>
</head>
<body>
<p>This is a view of miscellaneous information for a Linux system, as the following example shows:
<pre><img src="system.gif"></pre>
<p><b>Module options:</b>
<ul>
<li><i>-C</i> <i>(only available for ssh on UNIX client)</i>
<br>Whether data compression is used on all data between client and server (useful on slow connections, see <i>ssh</i> manual for detailed information).
<li><i>-i file</i> <i>(only available for ssh on UNIX client)</i>
<br>Selects a file from which the identity (private key) for authentication is read (useful if an authentication agent is not running). It must not be protected by a passphrase.
<li><i>-p port</i> <i>(only available for ssh on UNIX client)</i>
<br>Port to connect to on the remote host.
<li><i>-r (--remote) [[rsh|ssh]://][user@]host</i>
<br>remote monitoring using <i>user</i> as logname on remote host <i>host</i> (<i>rsh</i> or <i>ssh</i> facilities must be properly setup). If <i>user</i> is not specified, current user is used as logname on remote host. The protocol is either <i>ssh</i> or <i>rsh</i> (used by default). The module title is set to <i>system(host)</i>.
<br>When there is a communication error with the remote host, the data cells in the <i>CPU speed</i>, <i>CPU MIPS</i>, <i>users</i> and <i>processes</i> rows are set to the numeric void value (displayed as <i>?</i>), while the other cells are emptied. A descriptive error message is also generated in such a case.
</ul>
<p><b>Notes on remote monitoring:</b><ul>
<li>Using <i>ssh</i> is strongly recommended, as <i>rsh</i>, while being much less secure is also less efficient, as it requires creating a new session for each poll.
<li>On a Windows client, you must use the <i>putty</i> software package (see <i>install.txt</i>), which does not support <i>rsh</i> in non interactive sessions. Consequently, the <i>-r (--remote) ssh://session</i> syntax is required to remove any confusion (where <i>session</i> has been added to the running <i>pageant</i> application).
</ul>
<p><b>Examples:</b>
<pre>$ moodss system -r jdoe@foo.bar.com
$ moodss system -r ssh://jdoe@foo.bar.com
$ moodss system --remote foo.bar.com</pre>
