That's not the setting that I was thinking of. But, yes, it's within
the group of settings.

tcp_fin_timeout seems to be one of the values I was thinking of.

There are a number of TCP related sys controls.

Link - IP Sysctl - /proc/sys/net/ipv4/* Variables
- https://www.kernel.org/doc/html/latest/networking/ip-sysctl.html

Admittedly, I've so rarely needed to change any timeout settings.
Plenty of other settings, but not timeout related.
