RTM sniffing device not found

I am trying to configure capture and communication ports for my clients AMD. After i go through the rtminst menu configuration (set custom driver, set capture mode as normal) and apply to save the changes i am presented with this error:

Applying changes... ERROR: RTM sniffing device not found!

Restoring original configuration...


Ive looked through the documentation and community to try and find out more about this error, but with no luck. Can anyone clarify what this error means when you are trying to apply configuration settings to an interface? Thank you in advanced for looking into this.  




Ive only run into this issue when trying to set the drivers to custom. I am able to do full configuration with native drivers, but once i try and apply to custom drivers i am given this error. I have checked the documentation and the NIC card is supported for custom drivers. Ive added the requested output files as well. In this case we are interested in eth0 and eth1.


Requested noNIC.txt

Requested noNIC.tar.bz2

Either rtminst was unable to save your changes of your NICs are somehow not visible in the system.

Please execute the following command on the AMD:

ifconfig -a > /root/noNIC.txt ; ifconfig >> /root/noNIC.txt ; lspci -n >> /root/noNIC.txt ; lspci -v >> /root/noNIC.txt ; tar -cvjf /root/noNIC.tar.bz2  /root/noNIC.txt /usr/adlex/config/rtm.config /usr/adlex/log/rtm.log

and provide us with the output.

This is know issue when AMD software is unable to compile customized drivers when Linux kernel is 2.6.32-504.el6.x86_64 and the remedy is to upgrade to build or stay on native driver. Are you permitted to upgrade so we can provide you with a fix?

P.S. The technical alert is about to be released very soon.


I have a similar issue with the same card. Linux version is 2.6.32-358.el6.x86_64. Where can I get the new build that fixes this issue?


Would you please verify the problem is the same by looking into:


file that shoudl contain entries similar to:

/usr/adlex/rtm/drivers/linux-2.4/linux-2.6.32-504.el6.x86_64/../pldos3/ixgbe/ixgbe_main.c: In function ‘ixgbe_clean_rx_irq’:

make[1]: *** [_module_/usr/adlex/rtm/drivers/linux-2.4/linux-2.6.32-504.el6.x86_64] Error 2

The message may differ as you're using different kernel and you may be using different driver, but please let us know.

If /usr/adlex/rtm/drivers/linux-2.6/linux-2.6.32-358.el6.x86_64/log.txt file does not contain such files you should rather provide us with lof files pack we requested from Nathan at 11/18.



So I understand your /usr/adlex/rtm/drivers/linux-2.6/linux-2.6.32-358.el6.x86_64/log.txt file has no errors like above (that would indicate you run into the same issue as Nathan) and the next step would be to check your rtm.log, but unfortunately the one inside provided  noNIC.tar.bz2 package is empty. I think we need another copy of /usr/adlex/log/rtm.log.

The previous files were taken from a identical AMD but not used yet. Here is the rtm.log from an AMD that has traffic.


Your Linux kernel looks to be OK.

The root cause you cannot use customized driver is that one of your sniffing cards is not supported:

L0 2014-11-18 21:10:32 rtm.setup:1000: Ethernet cards found: 
L0 2014-11-18 21:10:32 rtm.setup:1014: card 8086:1521 - RTM support - igb driver will be used.
L0 2014-11-18 21:10:32 rtm.setup:1012: card 8086:154d - no RTM support
L0 2014-11-18 21:10:32 rtm.setup:1424: I: p1p1 P: 0000:41:00.0 😧 8086:154d ND: ixgbe CD:
L0 2014-11-18 21:10:32 rtm.setup:186: rtm is configured to use native drivers

You can mix unsupported NICs with supported NICs as long as they all use the native driver.

  Thanks for your reply and information regarding this custom driver. Since this DCRUM deployment is in the building process I believe we should be able to apply that upgrade. Please let me know if i can provide any more information or what i can do to help in this process. Thanks again.


We already know you're on RHEL6, 64 bits, so all we need know more is the SSL engine you use for decryption.

You can verify this by executing:

grep "ssl.engine" /usr/adlex/config/rtm.config


Base on this we will be able to decide which kind of upgrade bin file you need.



Here is the output from that command: 



Let me know if you need anymore information. Thanks again.



That's all - you're ready to get the fix.

Let us know if you need instructions how to apply it.



I get the same error that Nathan when I try to configure the Capture port.

How can I fix the problem?






I believe you hit AMD on RHEL 6.6 won't start following Linux kernel upgrade to version 2.6.32-504 or newer known issue, please read the article that talks how to fix it.

Hi Adam,

It's fixed the problem.

Thanks a lot,



Thanks a lot Adam.

I'm downloading the fix and I'll install it.

I hope it fixes the problem.

Thanks again.

I have the same issue with  a customer and I have a question about the other DCRUM components.

I've downloaded the AMD 12.2.3 but I didn't find the binaries 12.2.3 for CAS, CSS, console RUM, etc.

Do they exist? If not, which version of these components works with an AMD 12.2.3?


FYI, the customer DCRUM platform is in version 12.2.1.

Thank you for your reply.

We're encountering the same issue. We use AMD version

We cannot upgrade our AMD version for now, so we need a fix.

When I try to donwload the fix from AMD on RHEL 6.6 won't start following Linux kernel upgrade to version 2.6.32-504 or newer I receive an error saying there is no releases available for the selected product.

As it been moved?

Thanks in advance for your help!
