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>
<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>

search the listserver archives. A few of us were actually in

<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>
