|
||
<a href="boot.html"><i class="glossterm">boot</i></a>) code, periodically sent out from a working
|
||
computer to infuse the ‘breath of life’ into any computer on
|
||
the network that has happened to crash. Machines depending on such packets
|
||
have sufficient hardware or firmware code to wait for (or request) such a
|
||
packet during the reboot process. See also
|
||
<a href="../D/dickless-workstation.html"><i class="glossterm">dickless workstation</i></a>.</p><p>The notional <span class="firstterm">kiss-of-death
|
||
packet</span>, with a function complementary to that of a
|
||
breath-of-life packet, is recommended for dealing with hosts that consume
|
||
too many network resources. Though ‘kiss-of-death packet’ is
|
||
usually used in jest, there is at least one documented instance of an
|
||
Internet subnet with limited address-table slots in a gateway machine in
|
||
which such packets were routinely used to compete for slots, rather like
|
||
Christmas shoppers competing for scarce parking spaces.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="break-even-point.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../B.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="breedle.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">break-even point </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> breedle</td></tr></table></div></body></html>
