I’m trying to debug some issues with an application, but as part of this I noticed some odd networking behaviour macOS ventura (also occurs on monterey) rancher 1.5.1 containerd

Copy code

nerdctl run -it --rm alpine

then run

ping 8.8.8.8

. I see:

Copy code

/ # ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=254 time=3166643.804 ms
64 bytes from 8.8.8.8: seq=0 ttl=254 time=3167642.102 ms (DUP!)
64 bytes from 8.8.8.8: seq=0 ttl=254 time=3168662.359 ms (DUP!)
64 bytes from 8.8.8.8: seq=0 ttl=254 time=3169650.931 ms (DUP!)
64 bytes from 8.8.8.8: seq=0 ttl=254 time=3170643.970 ms (DUP!)

This looks like a networking issue. Any ideas? A colleague is seeing the same. We originally saw within an app container

I tried on a Windows host (uses wsl) with Rancher desktop. Same local network. No issues, pings are normal at ~8-9ms and no DUPs. So some issue with the setup of the mac networking stack?

I can open up a github issue if it’s not obviously user error
