Klein probleempje

Ga naar: *klink hier* download Dr. TCP

Dan selecteer je de interface (netwerkaart) waarover je jouw internet ontvangt van jouw server.

Dan doe je dit:

How to check your ideal MTU setting:

First set your MTU to 1499 (Use for example the DrTCP utility by DSLReports http://www.dslreports.com/), then reboot your pc.
Now you can start to ping your ISP by using this command: ping -l 1400 -w 5000 -f http://www.???.???
(Replace the "?" with a valid URL preferably your ISP).

What does this command mean?:
-l 1400 : The MTU size in bytes with witch you are testing.
-w 5000 : Wait time in ms (If your host is far away you might want to raise it a bit)
-f : Adds a bit in the IP header so that the packet will not be segmented.

Start pinging with -l 1400 and raise or lower it until you stop getting the message "Packet needs to be fragmented but DF".
After you found your ideal MTU value add an ICMP-Header of 28 to the found value and you have your ideal MTU value.

Now set your found MTU value (Use for example the DrTCP utility by DSLReports http://www.dslreports.com/), then reboot your pc.
Now do NOT try to find your ideal MTU value again cause this won't work anymore (That's why you initially had to set the MTU value to 1499).

En zet je TCP RWIN op 32767

Dan zou het moeten lukken... dit moet dus op elke client!
