Troboushuting Network issues from Linux

I'm a network administrator and I recently switched to Linux (Mint 19.1) In the past couple of weeks I gathered the best tools and commands that helped me do my job without having to go back to windows. I was wondering what other Linux tools and commands I may need in my job as a network admin. Some of the tools and commands that I'm using now:

TOOLS

Angry IP Scanner

PuTTY SSH Client

KRDC

FileZilla

yEd Graph Editor

Zenmap

Wireshark

COMMANDS

sudo tcpdump - shows network trafficker

sudo netstat -tupln

netstat -nr - shows IP addresses

netstat -i - shows who many bites each network is using

netstat -tan - shows all the established connections

netcat - program lets you listen to the network on a specific port

nmap -A 192.168.0.0-255 - scan the network

nmap -v

Iwconfig - wifi channels

tranceroute - shows you the route that traffic takes and where these links break

lsof - lets you see what processes open which files

route - command both displays where the system sends traffic, and gives you the ability to change how the system delivers traffic

host - let you peek at the Domain Name Service, which maps hostnames to IP addresses.
