<div class="moz-cite-prefix">As you seem to have his ear, could I
suggest three things:<br>
<br>
1. Reset the timer if he receives *any* data.<br>
2. Increase the timer to something reasonable like 5 minutes.<br>
3. Use the command 'ping' with no arguments (not too frequently).
It will return a string "Not Allowed' on older versions and 'PONG
nn' (where nn is an incrementing counter on later versions). Later
versions will also allow 'ping <string>' which will return
'PONG <STRING>' if software wants to maintain their own
counter or whatever. The PONG (and any string) is always sent back
in upper case. <br>
<br>
Please, gently, point out to the author that failure to do
something reasonable may result in measures to prevent his stuff
from filling the logs with useless data. Please pass my email
address to him and encourage him to contact me for any help he may
need. <br>

<div dir="ltr">I believe he says, "and cranking up the timeout to
5 minutes". So wouldn't that mean he calls it every 5 minutes
and not every 15 seconds?<br>
<div><br>
</div>
<div>Regardless, he's obviously willing to change his code
to minimize the impact to our systems. He's obviously also not
a DX Spider expert. So, he asked a question of the people that
are supposed to know our systems the best - us - and all we do
is ridicule his guesses of what he should do? How about
instead someone who really understands the DX Spider code
works with him to modify his code for least impact?</div>
<div><br>
</div>
<div>Obviously even we're not sure of the answers. I saw a
comment from our own group about timeouts and I saw Mike
mention that "firewall/routers running NAT will sometimes
expire or otherwise lose NAT connection" so I'm not even sure
we know how to help him.</div>
<div><br>
</div>
<div>So again, how about we approach this from the positive side
and work with him to minimize the impact of HamClock on our
systems instead of walling them off?</div>
