your explanation match perfectly to my observation :-)
I just tried to disable any ipfilter on the failing host. that changes
Also I guess the failing host don't support TCP FASTOPEN at all:
# cat /proc/sys/net/ipv4/tcp_fastopen
cat: /proc/sys/net/ipv4/tcp_fastopen: No such file or directory
# uname -r
Even if compiled in, can I control TCP FASTOPEN usage on application level?
I've other hosts with an without kernel support for TCP FASTOPEN.
Both classes can resolve the domain in question.
On a plattform with broken TCP FASTOPEN support ( even if noct
supported by the kernel)
I currently cant disable it, I would need an other unbound binary - right?
