To: =?UTF-8?Q?Ren=C3=A9_van_Dorst?= Content-Type: text/plain; charset="UTF-8" Cc: WireGuard list List-Id: Development discussion of WireGuard List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , This is pretty strange looking, and appears like it's a userland issue -- like the versions of ncat or ss or whatever weird scripting hacks in netns.sh aren't working well with the tools installed or some networking sysctl I forgot to toggle... Maybe one quick way of testing if it's an ss issue (old RHEL tools, or the like) would be to change the function body of waitncatudp into just `sleep 2` or something.
