In my tc configuration (shown below) in one class all bandwidth is shared among connections equally, but I want to share bandwidth among all IP addresses equally.

Now:

192.168.0.2 - 38KB/s
192.168.0.2 - 38KB/s
192.168.0.2 - 37KB/s
192.168.0.3 - 39KB/s
192.168.0.4 - 40KB/s

Expected:

192.168.0.2 - 23KB/s
192.168.0.2 - 21KB/s
192.168.0.2 - 22KB/s
192.168.0.3 - 63KB/s
192.168.0.4 - 65KB/s

Is it possible without creating class for each IP address? Because I have big subnets to manage like 10.0.0.0/8.

These are my iptables rules

ipset add src_set 10.0.0.0/16
ipset add dst_set 192.168.0.0/16

-A FORWARD -m set --match-set src_set src -m set --match-set dst_set dst -j CLASSIFY --set-class 0001:0011

These are my tc rules

~# tc class show dev eth1
class htb 1:10 parent 1:2 leaf 10: prio 3 rate 1000Mbit ceil 1000Mbit burst 126375b cburst 126375b
class htb 1:2 root rate 1000Mbit ceil 1000Mbit burst 126375b cburst 126375b
class htb 1:11 parent 1:2 prio 3 rate 1000Kbit ceil 3000Kbit burst 1725b cburst 1974b

~# tc filter show

~# tc qdisk show
qdisc htb 1: root refcnt 2 r2q 10 default 10 direct_packets_stat 0

On my Ubuntu 12.04 when I plug in usb device, under dev directory tree usb device is added like this:

/dev/bus/usb/001/001

On my CentOS 5 added like below:

/dev/bus/usb/devices/2-1.4/

lsusb needs usb devices to be created under /dev like first one. To solve it when I try to link them manually, OS gives 'No such file or directory error.', but linking same directory can be done under ubuntu without a problem.

CentOS:

ln -s /dev/bus/usb/devices/2-1.4/descriptors /sys/bus/usb/001/001
ln: creating symbolic link `/sys/bus/usb/001/001' to `/dev/bus/usb/devices/2-1.4/descriptors': No such file or directory

In ubuntu creating under /dev/bus/usb is not giving errors.

When I plug in my usb device under CentOS logs are like this:

What can be the cause and how can I solve it?

After I upgraded from kernel 2.6.18 to 3.5.3 modeswitch started not to work for me. Although lsusb shows my usb modem, usb_modeswitch does not switch it. My system information is like below. I ran lsusb, dmesg, usb-devices and usb_modeswitch their output is like below. usb_modeswitch instead of switching my modem it says "No devices in default mode found. Nothing to do. Bye.". Can you offer a solution?

I have 3com 4500 switch. I can got ram and CPU info with these:

1.3.6.1.4.1.43.45.1.6.1.1.1.3 - 1 Minute CPU AVG
1.3.6.1.4.1.43.45.1.6.1.1.1.4 - 5 Minute CPU AVG
1.3.6.1.4.1.43.45.1.6.1.1.1.2 - 5 Second CPU AVG
1.3.6.1.4.1.43.45.1.6.1.2.1.1.3 - Free Memory Remaining

But I could not find other information that I need, neither I could find MIB of 3com 4500.

I need:

  • Bandwidth rating of ethernet interfaces
  • Usage density of ethernet interfaces

And also some info from logs like:

  • Collision
  • Unexpected acts on ports

Can you give me some advices for these and from where can I find MIB of 3com 4500 switch?

switch mib 3com
