I once got hold of some small server flood tool, and since I lost that I wrote a crude Perl script that just sends these empty UDP packets to a given address. I can mail it if its any use to you.

When sending about 50 packets per second (probably something close to the tick frequency) it will introduce heavy lag on the server.

But a good server admin usually has patched this up, for example via DoS Attack Fixer or something.

Thus I'm still using a patch that covers this up.

Why the engine replies to empty packets with a full update? Is there

Every frame, the engine will sleep until it’s time for the next tick.
However, the Sleep system call may be imprecise and wake the process up
slightly later than intended. Setting host_timer_spin_ms will reduce
the
value passed into Sleep by that many milliseconds, but will cause the
process to busy wait for longer while it waits for the next tick and
thus
increase CPU usage. The var will not improve your framerate if you’re
constantly below 66 (i.e. a bogged down server), but may improve
consistency
on a sub-second scale.

Can anyone from Valve comment about host_timer_spin_ms?

This seem to make the FPS more consistent when enabled, it always
stay at
66. When it's disabled, it's mostly between 60-70.

Yes, I am very relieved that this Major Update is not one of Valve's
infamous Friday Updates.

Well, at least they're doing a major update on Wednesday instead on
Friday

thanks for the heads up

Im guessing we'll need to change this on our prophunt servers, or does
anyone know if the ph mod takes care of it?

I'm guessing the default is that it will show the icons. But if your

work because they changed it...

Hi there,

What if I don't have mp_show_voice_icons in my server.cfg ?

We’re going to have a mandatory TF2 update coming Wednesday
afternoon/evening. This is just a heads-up that it’s coming so that
you can
be prepared.

There is one change that might require a change to server configs:
tf_show_voice_icons has been renamed to mp_show_voice_icons so that
it’s
more generic.

Thanks,
Tony
