network sysctl in jails

[Scheffenegger, Richard]

Hi,

I wanted to check with you here, if there is a way to set up a bootup configuration similar to /etc/sysctl.conf, for each jail / vnet, to configure TCP stack options like ECN for example..

Doing a jexec <n> sysctl net.inet.tcp.ecn.enable=1 works as expected manually, and I could script that somewhere, but wondered if there is a  builtin-method / recommended config file for this.

Best regards,
  Richard
