Network Management

Hello,

I'm strugglig to buid an IMC Backup adapter for Palo Alto Networks firewalls (PAN-3220 & PAN-220 with PAN-OS 9.x). I have tried to buld it with both CLI and TFTP, but without success.

If someone in the community has ever try to perform this exercice, I would be gald to receive any guidance or suggestion.

Thanks

Ray

Hello,

Which existing adapter scripts are you basing your Palo Alto adapter on? I would suggest checking out the existing adapter for F5 Networks, as they should be fairly similar in terms of backing up a file (.gzip) instead of a plaintext configuration.

When you test your adapter on your devices, you should make sure that imccfgbakdm process is set to DEBUG (via System Configuration > Log Configuration page). After the backup fails, you would hopefully be able to see details about why it failed in the respective logfile, under iMC\server\conf\log\imccfgbakdm<current-date>.txt. If iMC was able to log in and then failed at some point, it will generally provide you with the CLI output up until the failure happened, so you have some hint as to what went wrong.

As for guidance on how to build adapters, I guess you are already aware of the section on Customizing iMC in the Administrator Guide. There is also a very helpful third-party doc called "HP iMC 7 customization" that you can find online which may help.

If you are getting some particular error with the backup, you could post it here, and perhaps we can help you out if it's something we've seen before.

Thanks for the advice and sorry for the delay ...

I seems the problem was related the parser, and I took me a while tring to uderstand how this works.

Nervertheless I have rebuild the adapter from scratch and now it seems to work fine, despite ERRORs in the log (see extract below):

It looks like the system is looking for a ... adapter\Custom ... directory that I do not have.

Is there something wrong with my setup, or can I just ignore therse errors.

Hello Ray,

Sorry for the delayed response here as well. I think you could generally ignore such errors - though you may need to delete and re-add your Palo Alto device to iMC after making changes to adapter-index.xml SysOIDs for Palo Alto. I've seen some issue where iMC does not automatically re-detect the adapter to use when such changes are made.

Looking through that log extract, it seems the backup process does start with the CLI method - Begin to run by cli. - so I wonder if there may be more relevant errors further along in the log? If the iMC backup fails at some point after logging in to the device, it will generally provide the CLI output up to the point where it failed/timed out in the log. Do you see anything like this?

Thanks for your reply.

As I said currently it works fine, but it took me a while to make it work.

I had to rebuild the adapter, delete and re-insert the device.

The original adapter version from IMC did not work with my version of FW (PAN-OS 9.x), and that’s the reason why I’m using a new adapter with CLI exclusively.

Concerning the errors I posted, I have already seen those with a number of working adapters.

As it is always nasty to have useless errors, especially when you troubleshoot something and are not aware of a correct behavior, I was just asking if there is clean way to remove them.

So as it seems not possible, we will just continue to live with them.

Thanks

Ray
