It serves a crucial function in helping Chooser loadbalance. It was created by members of the Pedagogical Tools Group under the supervision of Computer Science professor James Rogers, but its authorship slot was left blank. Its contents can be viewed below. </ins></div></td></tr> <tr><td colspan="2"> </td><td class='diff-marker'>+</td><td style="color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">==Script Contents==</ins></div></td></tr> <tr><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.TH &quot;NWD&quot; 8  </div></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.TH &quot;NWD&quot; 8  </div></td></tr> <tr><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.SH NAME</div></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.SH NAME</div></td></tr> <tr><td colspan="2" class="diff-lineno" id="mw-diff-left-l61" >Line 61:</td> <td colspan="2" class="diff-lineno">Line 64:</td></tr> <tr><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.SH &quot;AUTHOR&quot;</div></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>.SH &quot;AUTHOR&quot;</div></td></tr> <tr><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"></td></tr> <tr><td class='diff-marker'>−</td><td style="color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del class="diffchange diffchange-inline">Also don't know about this.</del></div></td><td class='diff-marker'>+</td><td style="color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins class="diffchange diffchange-inline">Unknown</ins></div></td></tr> </table> Mafero10 https://wiki.cs.earlham.edu/index.php?title=NWD&diff=14226&oldid=prev Aareid10: Created page with ".TH "NWD" 8 .SH NAME nwd \- New Wheel Daemon .SH "DESCRIPTION" .PP NWD monitors the CPU, memory, and network loads for a given machine, and keeps track of the number of open d..." 2013-02-06T20:02:56Z <p>Created page with &quot;.TH &quot;NWD&quot; 8 .SH NAME nwd \- New Wheel Daemon .SH &quot;DESCRIPTION&quot; .PP NWD monitors the CPU, memory, and network loads for a given machine, and keeps track of the number of open d...&quot;</p> <p><b>New page</b></p><div>.TH &quot;NWD&quot; 8 <br /> .SH NAME<br /> nwd \- New Wheel Daemon<br /> <br /> <br /> .SH &quot;DESCRIPTION&quot;<br /> .PP<br /> NWD monitors the CPU, memory, and network loads for a given machine, and keeps<br /> track of the number of open displays, as well as the number of displays it has<br /> committed to serve.<br /> .PP<br /> NWD performs logging in /var/log/nwd/<br /> .SH &quot;INTERACTING WITH NWD&quot;<br /> Remote hosts can interact with NWD by sending UDP packets to port 49177, the list of packets NWD responds to are as follows:<br /> <br /> \fBr &lt;display&gt;\fP<br /> .PP<br /> Make reservation for &lt;display&gt; where &lt;display&gt; is X displayname<br /> .PP<br /> \fBx &lt;display&gt;\fP<br /> .PP<br /> Cancel reservation for display<br /> .PP <br /> \fBs &lt;display&gt;\fP<br /> .PP<br /> Select reservation for display.
