Hi,

It looks like perhaps in your copy of blocking-write.pkt you have removed the line:

../common/set_sysctls.py /proc/sys/net/ipv4/tcp_min_tso_segs=10

Is that so?

If that is not the issue, then can you please share the output of the following commands, so we can see exactly which version of the scripts you are using, and what OS distribution and kernel:

git remote -v | grep packetdrill git log --oneline | head -2 cat /etc/lsb-release uname -r

Thanks!

Hi Neal,

I didn't remove the line. Below is the verbose output of command.

Below are git version, OS distribution and kernel:

BTW, I found if I add a blank link. `../common/defaults.sh ../common/set_sysctls.py /proc/sys/net/ipv4/tcp_min_tso_segs=10

` I could execute the script succeed.

The blocking-write.pkt script works for me as-is with an Ubuntu 20.04 machine with a kernel based on v5.13.12. I'm not sure why it's not working in your environment. If you are able to find a root cause, please feel free to submit a patch. Thanks!
