Hi, All, I implemented the following qos scripts in my Linux gateway (redhat7.3, kernel 2.4.18), put ftp server (10.10.3.49) on one side (eth0 nic) and ftp client (10.10.5.3) on the other side (eth1 nic). I tried to up load a file (211kbytes) from client to ftp server. I wanted to see a 22kbps transmission rate. Quite surprise, the ftp client showed transmission rate as 6.8e+02 kbytes/s (211k transmitted in 0.3 seconds). It was the same as it without qos implementation. So the conclusion is the QoS was not working at all. Could anybody tell me what's wrong with the setting? Thanks,
James
