Sharing my initial config

This is not an issue. I'm just sharing my initial config for ubuntu 16 LTS

Thanks, I've added a link to this in the readme

Here's a setup script for Ubuntu:

Thanks for the script 👍

I've just tried your script, and generally it works well.
However, with the rc.local, the line appears after the exit 0, which I think it needs to go before.

@hackzilla @claytondukes

Assuming that "exit 0" will always be the last line:

Remove last line
sed -i '$ d' /etc/rc.local;

Add Transmit Queue Length
echo "/sbin/ifconfig ${netIF} txqueuelen 10000" >> /etc/rc.local;

Add exit 0
echo "exit 0" >> /etc/rc.local;

Or in one line:
grep -q "/sbin/ifconfig ${netIF} txqueuelen 10000" /etc/rc.local || { sed -i '$ d' /etc/rc.local; echo "/sbin/ifconfig ${netIF} txqueuelen 10000" >> /etc/rc.local; echo "exit 0" >> /etc/rc.local; /sbin/ifconfig ${netIF} txqueuelen 10000; }
