NDP Table Data Missing (GUI)
-
I have built ndp with debug symbols for testing. It would be great to get a core dump from this version
-
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.

- Download the
ndp.fullfile from Redmine (this is the ndp binary built without compiler optimizations and with debugging symbols). - Navigate to Diagnostics > Command Prompt and upload
ndp.fullto pfSense, it should reportUploaded file to /tmp/ndp.full. - 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. - Now run
mv /tmp/ndp.full /usr/sbin/ndpand thenchmod +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 newndp.corefile will be at/root/ndp.core, download this file and share it with me cmcdonald<at>netgate<dot>comThanks

Perfect.

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

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.️
