When work tasks pile up into mountains, management networks and systems become very stressful. No one can know how long it will take to complete today's tasks, rather than doing yesterday's things today! In the face of many network system tasks that are not completed today, we would like to have any emergency tools that can be used.

1. Server configuration and script

◈ NixCraft

Use the search function of the site. After more than ten years of regular updates, it is everywhere in gold! Useful scripts and handy tips can solve your problem right away. This is the second option I use when I use Google.

◈ Webmin

It gives you a nice web interface to help you edit your configuration files remotely. It reduces the amount of time spent in processing directory paths and sudo nano, which is handy when you're working with multiple clients.

◈Linux subsystem under Windows

The reality in modern workplaces is that most employees run Windows, and the growing devices in the server room run Linux. So sometimes you will find an attempt to perform administrative tasks on the Windows desktop.

What do you do? Install a virtual machine? If you install the compatibility layer of the Linux subsystem that is currently available for free in Windows 10, it is actually much faster and much less configuration.

This gives you a Bash terminal window where you can execute Bash scripts and Linux binaries on your local computer, full access to Windows and Linux file systems, and installation of network drives. It includes Ubuntu, OpenSUSE, SLES, Debian, and Kali distributions.

◈mRemoteNG

This is an excellent SSH and remote desktop client when you have more than 100 servers to manage.

Setting up the network

◈ Expandable IP addressing scheme

The scary thing about IP address exhaustion is that when the IP address is exhausted, the network has become large enough, and the new addressing scheme is known to be expensive and painful.

At some point, IPv6 will come to save the world. But before that, no matter how many wearables, tablets, smart locks, lights, security cameras, VoIP headsets, and espresso machines the world threw at us, these unchanging IP addressing solutions should make us move on.

◈ Linux Chmod permission memo

A short but useful Bash command memo can help you set permissions over the network. So, when the customer service department's bill falls into the ransomware scam, you can just restore their files, not the entire company's files.

◈VL VLSM Subnet Calculator

Just enter the number of networks you want to create from the address space, and the number of hosts each network needs, and it can calculate what all subnet masks should be.

Single-purpose Linux distribution

◈ Porteus Kiosk

This tool is used to help you lock a computer to a browser. With a few tweaks, you can even lock your browser to a specific website. It is very convenient for public access machines. It can be used with a touch screen or keyboard mouse.

◈ Parted Magic

This is an operating system that you can boot from a USB drive that can be used to partition disk drives, recover data, and run benchmarking tools.

◈ IPFire

It is a very reliable software suite that is easy to set up and configure and has a range of plugins that can be extended
