Must-Have Tools for Network Engineers

1. Putty / Super Putty (free)

2. Notepad++ (free)

3. Wireshark (free)

4. NMap (CMD) / ZenMap (GUI) (free)

  : network device scan하는 툴

5. Python (free)

  : Python script를 만들어 자동화 가능. notepad++사용하거나 다른툴로 사용

6. GNS3 (free)

7. Oracle VirtualBox (free)

8. Microsoft Visio

  : NW diagram, Rack diagram, flowchart만들때 유용. alternate툴로 draw.io를 사용하면 web에서 바로 사용가능

9. IPerf (free)

  : command라인을통해 bw를 측정가능. 설치할필요없이 두개의 디바이스에서 run하면 하나는 서버, 다른하나는 클라이언트로 동작

10. MultiPing

  : 여러대의 서버로 동시에 ping 할때 유용

11. Cisco Packet Tracer (Free)

  : GNS3와 비슷하지만, cisco에서 만든 프로그램. 기본적인 Cisco 기능 시뮬레이션하기 좋음

12. SolarWinds Engineer's Toolset (ETS)

  : SolarWinds ETS is an industry favorite, delivering 60 essential network engineering tools. This is truly an all-in-one solution built to eliminate the need for network engineers to adopt and use multiple tools, which can be time-consuming and costly. With ETS, every network engineering tool you could possibly need is available through a centralized dashboard. The key features of ETS include automated network discovery, real-time monitoring and alerting, powerful diagnostic capabilities, enhanced network security, and integration with SolarWinds Network Performance Monitor (NPM). NPM중 Wan Killer Traffic Generator를 통해 실제 트래픽테스트가능.

13. Paessler PRTG

  : 네트워크 관리하는 툴로 많은 회사에서 사용됨

14. iReasoning MIB Browser 

  : SNMP테스팅하는데 사용되며, Windows/Linux/Mac에서 사용가능

15. WinMTR/MTR

  : WinMTR is used to capture packet drops for a particular path in extended period of time. It uses traceroute and keeps on running for a defined duration, at the same time also captures the number of packets dropped in that path. Very useful in case you are troubleshooting performance issues in a certain path.

16. Multicast Hammer

  : Multicast hammer is an excellent tool to test multicast, it works in both client and server mode. I found it very useful when to practice multicast or while testing it in a production network or while troubleshooting some weird multicast issue.
