[bwm-tools-tech] Not shaping anymore (Where to troubleshoot)

[Andrew N. <and...@gm...>]

I had bwm-tools running in production for about 5 months. I had a
harddrive go bad in the box last night. So lucky for me I had backups.
I run my server in bridge mode so traffic continued to to flow so I
don't think I made any stupid mistakes restoreing the backup because I
was in a rush. Here is what I have found so far no shaping is occuring
for any IP's listed, bwm-monitor will not work over ssh and traffic is
for sure flowing through the bridge again.

The box is bridged and has an IP of 192.168.100.10. The clients all
connect using the 10.1.1.x subnet. The client "Office" should be
limited to about 256k both directions and total bandwidth usage should
 be about 256k.

What is wrong? What won't bwm_monitor work? bwm_montior will just sit
there when I run it no user interface appears, the only way to get
back to the console is to 'ctrl c' which causes a segmentation fault.
Where do I start to troubleshoot? It appears that everything starts
fine. I did upgrade from Fedora Core 4 to CentOS 4.3 on the new drive
but other than that everything should be identical.

My once working config is pasted below (minus some unimportant data):

While definitely not qualified to speak for BWM-Tools, I highly suspect (from 
doing similar myself) that you are going to have to actually compile the 
bwm_monitor, bwmd, etc on the new OS (Centos) versus just copying it over 
from backups (if this is actually what you did).

If you compiled bwm from source on the Centos box, and simply copied your 
configs in, then something did not go right in the compile, go back and do it 
again and pay particular attention to the configure logs and the output of 
the make, make install.

I did compile from source on the new box and then just copied over the
config files. I will do some more testing and see what I can see. It
worked on the bench before I put it in. The only difference was on the
bench it was shaping traffic from the same subnet as the bridge. Could
this be a problem?

[bwm-tools-tech] Not shaping anymore (Where to troubleshoot)

[someone k. <gun...@gm...>]

Hi Andrew,

You can try either of the steps,

In you running configuration just add the iptables rules

  iptables -A INPUT -i lo -j ACCEPT

      OR you can append this firewall.xml tags and reload the bwm_firewall
-l

#in the acl classes
<class name="loopback">
  <address src-iface="lo"/>
</class>

# In control lists inside the filter table in input chain add a rule

<rule name="loop" target="ACCEPT">
  loopback;
</rule>


After trying one of the following steps try running bwm_monitor.
Check for the traffice shaping and make sure of it.
