The sh/h result will be user specific so you see simultaneous

<div style="overflow-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">I’m
in regular conversation with the author of HamClock.
He’s aware of this and is very open to suggestions.
<div><br>
</div>
<div>He’s already made a number of changes over the last
few versions following my feedback to reduce the
amount of traffic that HamClock generates, a big one
last year was switching from regular keep-alive
commands every few minutes down to just sending a ping
if there’s no activity for ten minutes.<br>
<div><br>
</div>
<div>I have around twenty HamClocks connected to my
node with only an FTTC connection (80Mbps down,
20Mbps up) and it’s not swamping my connection at
all. I use HamClock myself and find it a very
useful tool so I personally don’t have a problem
with people connecting to my node using it.</div>
<div><br>
</div>
<div>
<div>At the moment, when a HamClock is connected to
a DX Spider and receives a spot, it sends a
show/heading command so it can plot the received
spot on the map. If there’s any alternative to
this, I’m happy to pass it on to him.</div>
<div><br>
</div>
<div>If anyone has any suggestions as to how he can
reduce this but still provide the same
functionality, I’m very happy to pass them on and
I’m sure he’ll look into it.</div>
<div><br>
</div>
<div>But describing HamClock as sh*t software and
being abusive isn’t the way to go here. </div>
<div><br>
</div>
<div>I’m wondering if he can somehow cache the cty
file locally on the HamClock and use that as a
lookup.</div>
<div><br>
</div>
<div>I will mention to him that this subject has
been raised again.</div>

An alternative should be agreed upon.
Let's not condemn the author of clock.
It's a very useful application and does

with him to see what we can do to make it
work within acceptable limits.<br>

Hi Steve<br>
<br>
Let us know how to take down this s**t
piece of software.<br>
The command sh/head is only traceable in
the debug file as I know.<br>
<br>
@Dirk<br>
Is there a way to create/make a log file
that contains this type of commands on a
month bases? (like log/01.dat)<br>
Then we can create a fail2ban filter for
it (and other cmds).<br>

Steve, I have a couple of ideas I may
try to discourage the abuse. I'll post
results if they work.<br>
And another solution may be to encourage
the author of hamclock to start his own
node just for hamclock. He could then
add all the features he wants.<br>

<div> Steve, It depends on what
data hamclock is seeking. Why
all the show/heading requests by
every hamclock user every
second? It makes little sense.
Does someone know the originator
of hamclock who may be able to
offer a solution? For dxspider
could there be an automatic
rejection of some or all
commands by those hiding behind
set/nohere? Before I start the
pain of rejecting multiple ips,
I'll wait patiently to see if
another solution is offered. .<br>
