Hello, When I try to install DSMARK, I have : # tc qdisc add dev eth0 root handle 1:0 dsmark indices 64 set_tc_index Unknown qdisc "dsmark", hence option "indices" is unparsable all the qdisc are compiled as modules the module sch_dsmark.o is loaded but unused May I ask again the questions i have already asked in case of someone see them in this mail ? About DSMARK, I don't understand the way it works: - What is the (mask, Value) ? What is it used for ? - Does it mark the packet or the structure in the kernel ? - If i can mark the packet, how is it done ? Can i put only 'minimize delay', 'maximize throughput' and so on, or can i put what i want in the TOS field (for exemple 10110111) ? - Does it exist a howto only about DSMARK ? Thanks in advance for your help Manu
