<div class="moz-cite-prefix">I am struggling to understand why
HamClock requires a "keepalive" timer. It's a TCP based connection
that will have ICMP turned on (unlike certain TCP connections in
day$ job). This means that he *will* get notified if his
connection goes away ("connection reset by peer"). But, in any
event, if there is no output for a user for more than 11 minutes
(extremely tight filtering perhaps), the he will get a prompt. <br>
<br>
But, getting traffic - by itself - *should* reset his "keepalive"
timer. <br>
<br>
This has reminded me that I needed to have a method of changing
this "idle timer" prompt interval from 11 minutes. This will
appear in a release RSN. <br>

<div dir="auto">Thanks for the detailed information you provided
regarding HamClock. Based on your description and the reply
email Michael received from the author (Elwood), it's clear
that nothing has changed since he and I exchanged emails last
year. I brought up the same concerns with him that Michael
shared with examples and got the same overall response. Yes,
HamClock is really cool and displays lots of information on
your monitor screen. However, it gets all that data by
querying whatever cluster it's connected to. Elwood's reply
confirms these facts of this intense "resource hog" in action,
especially when multiple node users are running this software.
I read through the HamClock manual last year to get familiar
with it, especially the user settings. It was then that I
decided not to allow HamClock anywhere near my nodes. I don't
need to run HamClock myself, since I can see it in action on
the cluster window.</div>

<div dir="ltr">I use HamClock. In HamClock, there are three
panes that can display different information like SFI,
images of the sun, POTA/SOTA activations, VOCAP, Current
DXpeditions, and DXSpider spots among many others (see pages
5 & 6 <a

class="moz-txt-link-freetext">https://www.clearskyinstitute.com/ham/HamClock/HamClockKey.pdf</a>).
You can also set the panes up to rotate through that
information if you want to display more than three pieces of
information.
<div><br>
</div>
<div>Unfortunately, DXSpider spots is not one I run since my
logging program, CQRLog, is always displaying a window of
my spots.</div>
<div><br>
</div>
<div>I did look at the settings for you and the only
settings are the address, port, login, and up to four
custom commands. The custom commands default to blank, so
it could be that your users are adding commands that take
a lot of bandwidth. I'm not currently running a cluster so
unfortunately I can't look at the traffic for you.</div>
<div><br>
</div>
<div>One last thing. You can run HamClock on any linux
machine. You do not have to have his hardware. I'm not
running his hardware, only the software on an old netbook
I had laying around running Puppy linux. You too can run
it on any linux box in a window and test the traffic
yourself.</div>
<div><br>
</div>
<div>Here are some quick instructions if you want to quickly
run it on your local linux box.</div>
<div>1. Download the zip or tgz file from <a
href="https://www.clearskyinstitute.com/ham/HamClock/"
target="_blank" rel="noreferrer" moz-do-not-send="true"
class="moz-txt-link-freetext">https://www.clearskyinstitute.com/ham/HamClock/</a></div>
<div>2. Unzip/untar into a local directory.</div>
<div>3. cd into that directory.</div>
<div>4. Run "make -j 4 hamclock-800x480" where you
substitute one of the supported sizes (800x480, 1600x960,
2400x1440, 3200x1920). That will be the size of the fixed
window it will run in.</div>
<div>For example, on my big Ubuntu 22.04.02 machine, I did
"make -j 4 hamclock-1600x960"</div>
<div>5. Then run the executable you created. On my Ubuntu
machine it would be: "./hamclock-1600x960"</div>
<div>6. If you want to create a .desktop file so you can
have it integrated into your apps with an icon you can
click on, just let me know and I'll give you those
instructions.</div>
<div><br>
</div>
<div>It's actually a neat app that I'll run when I'm away
from my shack to see what's going on in the ham world
since it has news, propagation maps, and a ton of other
things.</div>
<div><br>
</div>
<div>Lastly, if I ever bring my node back up I'd be happy to
test.</div>

He is very responsive (he's added two

<div dir="auto">I'm glad you brought
this topic up. I have been planning
to voice my opinion. What you
tolerate as a SysOp is completely up
to your individual threshold level.
But, I have basically outlawed any
user on my nodes from connecting if
using HamClock. At one point, I had
6 users running the software 24/7. I
refer to this software as a
"resource hog" because of how much
data it requests for every spot,
then resends the users Name, QTH and
QRA every 15-30 seconds (which is
probably the default). I have a
modest computer and cable modem
setup for the cluster and home
network usage. If the connected user
callsign appears like this (AA4U),
they are probably using HamClock. I
will usually ask the user to connect
to a larger scale node, after
explaining why it's a resource hog.
