Why does webmin place a bunch of TIME_WAIT's in my netstat? It seems to slow
the box down. Is this normal?? Please email me directly if you have
suggestions on why this is doing this and how I can fix it. Thanks.

Hehehe...Not a Webmin question, Darkoth. This is more of a...um...TCP
question, I reckon.
Every connection made to your system follows certain rules. These are
the standards set down by the TCP protocol definition. One of them is
that when a connection is ended, the socket will be put into TIME_WAIT.
This is not a problem (unless by a bunch you mean several thousand),
and is normal operating procedure for any TCP server. The recommended
minimum for standards compliance is 60 seconds, or maybe it's 120...I
don't recall offhand.
And Webmin has nothing to do with setting up or breaking down those
primitive parts of the TCP connection. If you've got a problem with the
protocol, or your OS implementation of it, take it up with the protocol
authors, or the network coders of your OS.
And, again, unless you have thousands of them appearing in your netstat
with only one or a few users using Webmin, you don't have a problem.
You should see probably about 10 for a normal Webmin session with a
couple of windows open and logged in. Also, it should not slow the box
down, although I have noticed that when I use Netscape 6.01 on Linux,
Webmin does lead to a storm of PSM processes to be loaded (when SSL is
enabled) leading to very slow responses from the box.
