I spent what felt like a long time trying to find documentaiton on the net.ipv4.tcp_fin_timeout parameter. It’s easy enough to change it; but, finding out what things it might affect - not so much.
Turns out, there are a couple of options. First and best is to install kernel-doc rpm then examine the files under /usr/share/doc/kernel-doc#/Documentation. To find the specific file that had the info, I ran a simple find:
# find . -name \*.txt | xargs -i grep -<li> tcp_fin_timeout {}
./networking/ip-sysctl.txt
If, for whatever reason, you can’t install that rpm, a google search for your kernel rev should help. Specific to ip-sysctl.txt, the url below has an extensive list of kernel versions:
