This issue only crops up on certain systems, and I'm not sure why (mine is also affected)

One of the services pulls in nfnetlink_queue during startup which conflict with the IMQ virtual interfaces... Snort/DAQ was patched to avoid this issue but it's still occurring. The work around simply removes it

Forum is a bit quiet at the moment over the holiday period! However we are just other users trying to help where we can...

hmmm I've gotta take back what I said on this specific issue

I just tried to workaround and YES, it works for bandwidth manager.

Thanks TIM

Hi. Did you try the workaround Tim provided above? Once I entered in the commands, traffic was restored and limited to the speed I entered. Can you provide the steps you've performed so far and where it's still failing?

I also see Tim noted there's an open bug on this issue now.

Yeah so same thing here...

Fresh install of latest ClearOS, did all the updates.

Whenever I start

Bandwith manager

OR

QoS

both completely disable internet connectivity.


They're just completely broken, and there is absolutely no fix to be found anywhere.


Off topic but: for the life of my I can't establish connexion with the built in OpenLDAP server

Forum as been completely useless on all the problems I've run into... no help whatsoever...


I'm highly disappointed with this...

When I installed ClearOS I was CHARMED.

Just loved everything about it!

It had all the features I was looking for, with a clean GUI.

The problem is that the features don't work and they're ain't no support or community to help...


I'm about to switch back to PfSense

I haven't tried the blacklisting yet, but the modprobe command resolved it for me for now. Thanks so much for your help!

Please try running 'modprobe -r nfnetlink_queue' and then 'firewall-start -d' - everything should work normally again....

There is a known issue with the nfnetlink_queue module that prevents the QOS IMQ modules from working

To blacklist it permanently add it to /etc/modprobe.d/app-base.conf

EDIT: PS reopened the bug report relating to this issue

I've run into the same issue.

I'm able to run the firewall-start -d command but unable to grab the output since enabling QOS prevents me from connecting via ssh and outputting the command to a file "firewall-start -d > /tmp/firewall.txt" doesn't work.

I can see that when I make changes, they are taken. I've tried many different values as low as 32 and as high as 8000. They reflect in the lines below using a value of "2000" in this instance.

firewall: /sbin/tc class add dev imq0 parent 1: classid 1:1 htb rate 2000kbit prio 0 = 0
firewall: /sbin/tc class add dev imq1 parent 1: classid 1:1 htb rate 2000kbit prio 0 = 0
firewall: /sbin/tc class add dev imq0 parent 1:1 classid 1:2 htb rate 250kbit ceil 2000kbit prio 7 = 0
firewall: /sbin/tc class add dev imq1 parent 1:1 classid 1:2 htb rate 250kbit ceil 2000kbit prio 7 = 0

Output of "lsmod | grep net"
nfnetlink_queue 6330 0
nfnetlink_log 6694 0
nfnetlink 3180 2 nfnetlink_queue,nfnetlink_log

Setting 'BANDWIDTH_QOS="off"' in the /etc/clearos/bandwidth.conf file resolves the problem. I can't disable via the GUI since enabling the service prevents connections.

Hi Tim

Thanks for looking at this; however I ended up installing a pfsense gateway instead - not as easy to install/configure as ClearOS, but I already know how to set bandwidth throttling there and I needed a quick fix.

I have 2 other boxen to fiddle with and will try Clear again, but I am taking a couple of weeks away, so will not have feedback for you until sometime in September.

cheers
Ken

QOS should not be required no

After you have enabled the bandwidth manager, can you post the output of 'firewall-start -d'?

Also output of 'lsmod | grep net' would help too

I ran into this same problem.
