Re: Microsoft Windows ME and TCP/5000

I found "Backweb Server" running on my "New" HP
Pavillion and determined it was "factory" installed
for some kind of automatic updates.  HP tech support
didn't know anything about it.  You could install some
tcp port monitor like TDImon to determine what app is
running on the port.

Cheers,
Jeff

Quite commonly when you setup a multi-player FPS
type game they will
install a web-server that allows you to change
maps, kick players, etc
on the game server.  I know that this is the case
with Unreal
Tournament.  As for Quake3 I am pretty sure it
doesn't do this as it has
the ability to allow control of these game aspects
via the game itself.
You may want to check the docs for Halflife to see
if this is true.

Your right, UT installs a webserver on port 80 if
explicitly told so,
however you can change the port.
Youre right Q3a doesnt and the same is right for HL.
If you want to control
HL through a webserver you have to install some kind
of mod but normally
thats only feasible for a dedicated server, because
when ingame you can
change everything by means of the console(same goes
for UT, BTW). Even the
dedicated one can controled locally.
As for the port 5000, I also have ME running and
never seen any port 5000
listening. What about ICQ? ICQ tends to sometimes
open funny ports for
listening.
Good luck!

Hello,
  I've seen only a handful of unanswered
questions when researching this
subject on Google, but I've found what seems to
be a webserver running
on
port 5000 of my WinME box.  A "netstat -a" shows
UDP/1900 listening and
TCP/5000 listening.  ICS is not installed, F/P
Sharing is not enabled.

On this box I have installed Halflife & QIII
Arena off OEM CD's, and
LimeWire (a gnutella type client).  The Limewire
has since been removed
and
no references seem to appear for it the
registry.  Telnetting to port
5000
and trying a properly formatted http GET command
(or using a web
browser)
returns HTTP 1.1/400 Bad Request.  I've seen
references indicated
UDP/1900
is normal for ME (something to do with IP
multicast & PnP detection),
but
TCP/5000?  I'm bringing home my Network
Associates VirusScan software
from
work today.   (Shame on me, running w/out
protection for two weeks --
what
was I thinking!)   I was just curious if anyone
knew of a Trojan that
camps
an HTTP server on TCP/5000.  Perhaps I caught
something...
