pfatt - ngeth0 interface disappears

stephenw10

Hmm, potentially. Though I can see no reason that would remove the ngeth interface entirely. I guess netgraph itself could be hitting a resource limit. that we don't normally see.

SeaMonkey

I should have mentioned in my updated posts that I realized the ngeth0 interface disappearing was only happening when I ran the commands under the "Reset netgraph" section of the pfatt README and then failed to manually run the script to bring it back up afterwards.

Ah, I think you did mention that. Too many threads!

Hmm, so if it just stops passing traffic it could be something in netgraph overloaded. Though I would expect to see some log entries.

Can you see any debug info using ngctl status?

SeaMonkey

ngctl status returns No status available for all <path>. Did you mean ngctl show?

Here's what it looks like when everything's working.

Once I'm home again, I'll intentionally break things and see if the results are different.

Hmm, no I meant status but I'm also seeing the same output...

The status data might show more. If I could work out the syntax!
