NDP Table Data Missing (GUI)

@cmcdonald

I guess that is on me but I've no real idea how to install this or recover back to normal again.

I've downloaded the file I can see that a couple of move files / mv command's are needed but don't presume I know what I am doing - both pfSense and BSD are new to me. Oh and I only have my in-production Netgate devise to test with (gulp!).

That said, my NDP table has vanished again this evening...

...so perhaps that is a sign I should crack-on with this.

1. Download the ndp.full file from Redmine (this is the ndp binary built without compiler optimizations and with debugging symbols).
2. Navigate to Diagnostics > Command Prompt and upload ndp.full to pfSense, it should report Uploaded file to /tmp/ndp.full.
3. Still on Diagnostics > Command Prompt, enter mv /usr/sbin/ndp /usr/sbin/ndp.orig , This just renames your existing ndp binary so that the next step doesn't clobber it.
4. Now run mv /tmp/ndp.full /usr/sbin/ndp and then chmod +x /usr/sbin/ndp. The first command moves the new binary into the well-known location and the second command ticks the execute bit so that it can be, well, executed.

I would go ahead too and purge any existing core files with rm -f /root/*.core. Once you get an empty NDP Table again, there is a great chance that you've hit the issue and a new ndp.core file will be at /root/ndp.core, download this file and share it with me cmcdonald<at>netgate<dot>com

Perfect.

@RobbieTT Any updates? We are eager to obtain a core dump from anyone who can replicate using the debugging build of ndp binary

@cmcdonald

Not yet as this is my only pfSense device so I have to wait until the dark hours of the weekend to attempt it (remote working and all that).

I've kinda got used to having 2 routers when I was running EdgeRouters; it's more difficult to test things with only 1. I'm sure I will get another device at some point.

You should now have 2 emails - first with the core dump as per instructions and the second taken after a system reboot.

Good luck.

@RobbieTT Thanks for the core. We were able to track this one down!

@RobbieTT Has this happened since the fix?

@marcosm
No, the NDP table has been fully populated in the GUI since the fix.
