Oh... Well, what's a 'whoops' between hackers? (the good olde
fashioned kind)<br>
<br>
I went to the web page and, of course, understood the working
solution to put the 'disappeared' host names into the <font
size="4"><tt>/etc/hosts</tt></font>. That's a standard thing to
do on Windows and any Unix flavor I can think of. Personally, I
think it is a win. The one place where you <i>can't</i> do it as
easily is on a PANDA Tops-20 distribution, which will check the
domain <u>first</u> and wait for that resolve to time out before
checking the local hosts file (<font size="4"><tt>SYSTEM:HOSTS.TXT</tt></font>).<br>
<br>
So that means you have to <i>wait</i> for the time out, which,
whatever duration that happens to be is far too long for me. It's
quite infuriating, actually. <tt>SYSTAT</tt> immediately knows,
yet <tt>finger</tt> appears to hang and mail delivery slows to a
crawl. You can't know how to remediate unless you happen to be
familiar with the source code. Humph...<br>
<br>
Avoiding the time out means you have to put whatever host you want
into the domain files, the format of which is both arcane and poorly
documented. And then whack the resolver. Now you have two files to
keep in sync. That was one argument that I never won with MRC as
having it the other way around seemed to me to be easiest for
everyone.<br>
<br>
I finally edited my local copy of <font size="4"><tt>HSTNAM</tt></font>
to not drive me crazy and also gave DECnet hosts priority, which
then turned up a gap in Tops-20. <font size="4"><tt>HSTNAM</tt></font>
<i>really</i> wants the node number, even though the average user
can't do a blessed thing with it. If it doesn't get a number, then
it...well, makes something up. Of course, fixing all this broke
something else in MMAILR, which is another rabbit hole I have yet to
get myself out of.<br>
<br>
This all being said, would the correct assumption be that HP is
looking to pull its Stratum-1 server or just cut down traffic? I
can't remember where I read this, but apparently Stratum-1 servers
get <b>a lot</b> of traffic, so maybe HP didn't want to burn that
bandwidth any more. Or...?<br>

<p>Getting time on TCP port 37 is <i>old</i>. I only do it
because that is all I have until such time as I port
something smarter. Note the following from NIST: "We will
continue to support the "TIME" protocol that uses TCP port
37 for the forseeable future." So not responding on port 37
might not be a false negative, if only NTP is supported.<o:p></o:p></p>
