Hello Sir, I want some help from you. I have my configuration like this. I have three machines. PC1,PC2,PC3. hub hub PC1--------------------PC2-----------------------PC3 eth0 eth0,eth1 eth0 I want to work my configuration like diffserv. I am generating traffic from PC3 and sending it to PC1 via PC2(as a router)and from PC2 to PC1 also. So i have two kinds of traffic. I want to do these things: 1. Mark the packets going out from PC3 towards PC1 via PC2. 2. I have my rules and filters with tc in PC2. Means i want to contol the traffic from PC2. Based on the mark which i put on the traffic going out from PC3 i want to put the traffic in different-differnt classes. Means i want to filter the traffic based on the mark on traffic. It would be helpful if i am able to mark the TOS bits so that i can see it in tcdump or ethereal. 3. Traffic going out from PC2 and generated by PC2 itself should have different differnt mark so that the traffic can be filtered based on the mark. Please suggest sthing related to this. Waiting for your reply. Anish Mehta.
