UDP tracert ?

[seste]

hi,

i got a problem, when i wanna play (counter-strike) i got loss etc. all few minutes on every counter-strike server.

i allready talked to my provider but they, told me the usual stuff :) like, virus ping depends on server etc. i reinstalled my system, and im a advanced pc user, so it´s for sure clean :)

im wondering, couse when i ping, tracert or download i got no packetloss but ingame there it is, so i try to figure out where the problem is.

is there a programm which tracerts UDP ? couse when i ping with cmd.exe theres no packet loss, but ingame it is. its also when i ping with cmd.exe its about 200 ping and ingame its 30. so i guess the provider routes the udp packets different then the http icmp.

maybe my setup helps:

location: austria
dsl: ADSL 2mbit/384 up
router: thomso speedtouch 546

TCP properties for IP = 212.183.43.81 ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 0204055001010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1360
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your TCP Window limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 122 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

maybe anyone of you get a clue :) thanks in advance for a tip. :thumb:

why havent you blanked out your ip mate ????? silly

[seste]

its dynamic :) so it´s not important :P

I've seen UDP-Ping for *nix but not for windows.

Lotsa other factors that can affect loss beyond net traffic.

You may want to post something in the gaming forum. In the business world UDP is really used for streaming and the like only. Too unreliable for much else.

imo it´s for sure a udp problem. couse, when i ping its 200ms and ingame its 30. so i believe that the provider roots the udp different then the icmp request.

k is there any good network testing tool for windows for free to test my connection ? you know stuff like hops, loss, etc. which can help me to detect the problem ? :) would be fantastic.

Are you sure that the 'ingame pings' are accurate? I would trust a ping.exe from the shell much more that what a game's gui would tell me...

In any case - try nmap - http://www.insecure.org/nmap/install/inst-windows.html

k thx :) and yes im sure. couse i know how it feels to play with 30 ping or with above 50 or like the ping.exe says 200 =P

and the counterstrike netgraph is as far accurate, couse you see also spike lags.

it was a modem bug with the speedtouch 546 - new firmware or using the modem in multiuser solve the bug.
