These 11 must-have practical software for network engineers, don’t say Lao Yang is keeping it secret and not telling you

What useful software do network engineers usually use to improve efficiency?

In fact, there are many recommendations on the Internet, but it depends on personal opinion. You will know whether it is good or not after using it.

Lao Yang lists some software that he likes to use, hoping to recommend them to friends in need to improve your work efficiency.

1. SecureCRT

It is indispensable for device debugging and is a software that is frequently mentioned on the Internet. Secure CRT is an ideal tool for connecting to remote systems running Windows, UNIX, and VMS, and is also a must-have software for remote login to switches.

SecureCRT supports serial (console), telnet, ssh debugging logging and other functions, or putty open source software, most of the functions of crt are supported, but the interface is not very friendly.

It supports SSH, telnet, serial and other protocols, and the use of the Activator tray greatly reduces desktop clutter.

2. eNSP Simulator

eNSP (Enterprise Network Simulation Platform) is a free, scalable, graphically operated network simulation tool platform provided by Huawei.

Before the project is implemented, you can simulate the network configuration of the project, so that you can have a clear idea when implementing the project. It is a very practical software. Basically, all the people engaged in network-related projects will use it.

eNSP supports topology creation, modification, deletion, and saving, as well as device dragging and interface connection operations. It can preset a large number of engineering cases, which can be opened directly for practice and learning.

It can also simulate most of the features of Huawei AR routers and x7 series switches; simulate PC terminals, Hubs, clouds, frame relay switches, etc.

The advantage of this simulator is that it has a relatively comprehensive range of device types, a large number of device models, and provides usage examples and related documentation.

3. cisco packet tracer

Packet Tracer is a simulation software developed by Cisco for the Cisco Networking Academy for its CCNA (Cisco Certified Network Associate) certification to design, configure and troubleshoot networks.

It is very suitable for beginners of network. Not only can it efficiently build a network experimental environment, but its simulation working mode can also provide you with the composition and transmission of data at each layer of the network, and the processing process of various frames or packets.

It supports many devices, and each device provides many models of devices. This is still helpful for people who have never seen the real device.

However, its user interface is a bit complicated and the fonts are small. If you are not familiar with it, you will need to spend some time to adapt to it.

4. xshell

Xshell is a powerful and secure terminal emulator that supports SSH, SFTP, TELNET, RLOGIN and SERIAL. Xshell can be used to access remote servers in different systems under the Windows interface, so as to better achieve the purpose of remote control of the terminal, which is generally called remote control.

The users are mainly network administrators of large enterprises, network server managers of research institutions and universities, and technical geeks. Girls generally don't use it because the interface is too ugly.

If you can't find the free version of xshell, FinalShell is also okay, it is a domestic software.

5. Wireshark

Wireshark is a network protocol detection program that supports Unix and Windows. It can detect network communication data in real time and detect the captured network communication data snapshot files.

Network administrators use Wireshark to detect network problems, network security engineers use Wireshark to check information security related issues, developers use Wireshark to debug new communication protocols, and ordinary users use Wireshark to learn about network protocols... So, it is really popular.

6. Tmux

tmux is an excellent terminal multiplexing software, similar to GNU Screen, licensed under BSD, and generally used for Terminal window management.

The most intuitive benefit of using it is that after logging in to the remote host through a terminal and running tmux, you can open multiple consoles in it without "wasting" extra terminals to connect to the remote host.

However, tmux has a bug that causes the copy and paste shortcut keys of vscode launched from it to become invalid.

7. FileZilla

FileZilla is a free and open source FTP client software, divided into client version and server version, with all FTP software functions. The controllability, organized interface and simplified way to manage multiple sites make FileZilla client a convenient and efficient FTP client tool, while FileZilla Server is a small and reliable FTP server software that supports FTP&SFTP.

8. Cacti

Cacti is a network traffic monitoring and graphical analysis tool developed based on PHP, MySQL, SNMP and RRDTool.

Its main function is to use the snmp service to obtain data, and then use rrdtool to store and update the data. When the user needs to view the data, rrdtool is used to generate charts and present them to the user.

However, using cacti requires some knowledge of using net-snmp and rrdtool. If you want to customize the monitoring indicators, you also need some shell scripting or XML language skills.

9. winscp

WinSCP is an open source graphical SFTP client that uses SSH in Windows environment. It is also an open source file transfer software that supports multiple protocols.

It also supports the SCP protocol. Its main function is to copy files securely between local and remote computers. WinSCP can also link to other systems, such as Linux systems.

It also supports SFTP, SCP, FTP and other protocols for easy use. If you need to transfer files with your hands via FTP or use SCP to connect to a server, this is the right choice. It is open source, free and ad-free, so it is recommended.

10. Edraw

Many people are using Visio, so Lao Yang recommends a new software here.

Edraw is similar to Visio, a vector-based drawing tool that includes a large number of case libraries and template libraries. It can easily draw various professional business process diagrams, organizational charts, business charts, program flow charts, data flow charts, engineering management diagrams, software design diagrams, network topology diagrams, etc.

It uses full drag-and-drop operation, combined with a library of more than 4,600 commonly used graphic templates and a user-defined instance library to simplify your workload to the greatest extent.

Edraw is perfectly compatible with the advantages of Visio. If you get tired of Visio, you can switch to Edraw, you might find surprises.

11. CAD Mini Viewer

CAD Mini Viewer is a tool for quickly viewing CAD drawings. It has Android, iOS and PC versions. The software can view, mark, measure distance, take photos and record CAD drawings. It can be used offline, which is very convenient.

CAD quick viewing only requires about 20M of disk space, and DWG drawings open the fastest and display the smoothest.

In addition, the interface is extremely simple and easy to operate, so many people are using it. Chinese and steel bar fonts are displayed correctly without installing any fonts.
