Gargoyle Forum

Hi,
I have just upgraded my Linksys WRT54G v1.1 router from stock Linksys firmware to version 1.1.2 of Gargoyle and everything appears to work fine except I get no bandwidth monitoring information at all. If I upload the bandwidth data I get a csv file full of an error message as follows:
------------------
ERROR: Bandwidth query failed make sure rule with specified id exists and that you are performing only one query at a time.
------------------

I have static IP's assigned for my hosts though DHCP is enabled. I have not enabled any QoS functions.

Can anyone point me tpo what I have done wrong in my setup?

That is strange. It sounds like you're doing everything right (though as of 1.1.X releases you don't need to set static IPs, but it shouldn't make a difference if you do).

The only question I have is regarding your claim that you uploaded bandwidth information even though you say you installed Gargoyle straight from the linksys stock firmware. The only way to upload bandwidth information is by restoring a backup generated by Gargoyle, but you never used a previous version. So... can you be a little more clear what you did in terms of "uploading" bandwidth data?

I have tried and cannot replicate this problem, so in order to debug it I will need more information from you.

Can you please ssh into your router (if using windows use putty), and either post the output of the following commands below or send them to me via PM. These shouldn't reveal any critical information about your network, but some people feel more comfortable not posting this information in public and prefer to use PM:

Hi,
I should have used the word 'download' rather than upload. I pressed the button "Download Now" in the section labeled "Download Bandwidth Data" at the bottom of the screen for the bandwidth dispay options.

Ok, given the info you sent me, I still can't figure out what's going on -- it looks like the rules are getting inserted into iptables properly.

This is a bit tricky to debug, since I can't replicate what you are seeing.

Have you tested whether a reboot fixes the issue? The error you report seeing happens when a semaphore isn't released properly. This gets reset after a reboot. (Of course, that begs the question, how it got locked up in the firstplace, which is worrying).

Hi Eric,
Yes I have tried rebooting and also a complete power cycle. Nothing appears to make any difference. I have looked through the dmesg output (having logged in via ssh) and nothing jumps out at me as being wrong - though to be honest I would not know what to look for.

Are there any other log files I can check for correct functioning? Should I try executing a "Restore Default Configuration" from the web interface?

Thanks Paul

Try logging in via ssh as before, and running this, and then post the output:
No guarantees that will tell me what's wrong (based on what you've already told me, I suspect this command to give you an error), but it might help me figure out what to test next.

Hi Eric, As expected the command gives an error ...

This is going to be tricky to debug unless I can replicate the issue. The problem seems to be somewhere in the bandwidth module/iptbwctl library, which means in order to test I need to adjust and recompile some code written in C.

One last thing you might try: ssh in and then first turn off the bandwith monitor completely ( and make sure you don't have any quotas defined), and then reboot & exit: Wait a few minutes, and then log back in again with ssh. Then run the following, and tell me what the output is. Try visiting a website or something right after you execute the first command listed below, so that there is some data in the monitoring rule you're inserting. Then execute the second and third: If you want to turn the bandwidth monitor scripts back on afterwards (even though it's not working for you), you can run these commands:

Hi Eric,

Here is the result of issuing the commands as suggested. Sorry about the formatting:
