Network operation and maintenance is the key to ensuring the stable operation of network systems. It requires the use of a variety of software and tools for monitoring, management, and maintenance. The editor of Downcodes will introduce to you in detail the necessary software and tools for network operation and maintenance, covering the five aspects of network monitoring, configuration management, security protection, fault diagnosis and automated deployment, as well as related questions and answers, hoping to help you better Understand and apply these tools to improve network operation and maintenance efficiency.
Network operation and maintenance is an important part of ensuring the normal operation of the network system. The necessary software and tools involved include but are not limited to: network monitoring tools, network configuration and management tools, security protection software, fault diagnosis tools, and automated deployment tools. Among them, network monitoring tools are the eyes to ensure the healthy operation of the network. They can monitor network equipment status, service quality and traffic changes in real time, helping operation and maintenance personnel find problems in time and deal with them.
Network monitoring is an indispensable part of network operation and maintenance. It can provide real-time and comprehensive network status information. There are many mature network monitoring tools such as Nagios, Zabbix, PRTG Network Monitor, etc., which can help operation and maintenance personnel discover and solve network problems in a timely manner.
Nagios: It is an open source network monitoring system that can monitor network services (SMTP, POP3, HTTP, NNTP, ICMP, SNMP, FTP, SSH), host resources (processor load, disk usage, etc.) and more complex transactions (Such as remote script execution, etc.). Nagios has extremely rich plug-ins and can easily expand various functions.
Zabbix: Provides an easy-to-use graphical interface that supports distributed monitoring, agentless monitoring, automatic discovery, real-time monitoring and other functions. It also has good scalability and customization, and can adapt to the needs of network environments of different sizes.
Network configuration and management are key to ensuring that the network executes according to established policies and responds quickly to changes. Tools such as Cisco's Network Assistant and SolarWinds Network Configuration Manager can manage network device configuration, simplify the configuration process, and speed up deployment.
Cisco's Network Assistant: This is a network configuration and management tool provided by Cisco. It supports the configuration management of a series of Cisco switches and routers. Features a graphical interface that simplifies many network setup and configuration tasks.
SolarWinds Network Configuration Manager: This tool is used to automate configuration management, allowing network administrators to back up, manage and quickly update network device configurations. It can also monitor configuration changes, audit compliance, and more.
Network security is the core part of network operation and maintenance, so accordingly, tools such as firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and comprehensive security management platforms are indispensable.
Firewall software: such as Cisco ASA, pfSense, etc., is responsible for protecting network boundaries, preventing unauthorized access, and controlling traffic in and out of the network.
Intrusion detection and prevention systems: Such as Snort and Suricata, they can identify various attacks and suspicious activities and help enhance network security protection.
Diagnosing network problems quickly and effectively is the key to improving network operation and maintenance efficiency. Fault diagnosis tools such as Wireshark, Ping, Traceroute, Tcpdump, etc. can help operation and maintenance personnel locate and solve problems.
Wireshark: It is a popular network protocol analysis tool that can capture and analyze real-time data packets, helping to detect network problems, network intrusions, etc.
Tcpdump: It is a command line packet capture tool used for network fault diagnosis and network learning. Although it does not have a graphical user interface, it is powerful and capable of capturing and analyzing network traffic.
In modern network environments, automated deployment has become a trend in order to improve efficiency and reduce human errors. Automated deployment tools such as Ansible, Puppet, Chef, etc. can help network operation and maintenance personnel automatically manage network devices and services.
Ansible: It is a simple and easy-to-use automation platform that can be used to automatically deploy applications, manage system configurations, and orchestrate complex workflows.
Puppet: It is a configuration management tool that can help system administrators automatically manage the configuration and deployment of multiple servers.
Network operation and maintenance tasks span a wide range of tasks, and using appropriate tools can greatly improve work efficiency and accuracy. These necessary software and tools are just the tip of the iceberg. As network technology continues to develop and evolve, network operation and maintenance tools will also continue to be updated and developed. Operations and maintenance personnel need to continue to pay attention to the latest tools and technologies to be suitable for increasingly complex networks. environment.
1. Which software and tools are necessary for network operation and maintenance?
Network operation and maintenance work requires the use of some necessary software and tools to manage and maintain network equipment. The following are some common essential software and tools for network operation and maintenance:
Network monitoring tools: used to monitor network equipment and service status in real time, such as Zabbix, Nagios, etc. These tools can help operation and maintenance personnel detect and resolve network faults in a timely manner. Network configuration tools: used to configure and manage network devices, such as SolarWinds Network Configuration Manager, Cisco Prime, etc. These tools can improve the efficiency and accuracy of network management. Network performance testing tools: used to test and evaluate network performance, such as iperf, Wireshark, etc. These tools can help operation and maintenance personnel discover network bottlenecks and optimize them. Remote management tools: used to remotely manage and maintain network devices, such as SSH, Telnet, TeamViewer, etc. These tools make it easier for operation and maintenance personnel to manage and troubleshoot network equipment anywhere.2. How to choose suitable network operation and maintenance software and tools?
Selecting suitable network operation and maintenance software and tools requires considering the following factors:
Functional requirements: According to the specific needs of network operation and maintenance, select software and tools with corresponding functions. For example, if you need real-time monitoring, you need to choose a tool with real-time monitoring capabilities. User-friendliness: Choose software and tools with friendly interfaces and simple operations to facilitate operation and maintenance personnel to use and learn. Compatibility: Consider whether the software and tools you select are compatible with current network equipment and services to ensure they work properly. Support and maintenance: Choose software and tools with good technical support and maintenance services to solve problems encountered in a timely manner.3. In addition to the necessary software and tools, are there any other useful network operation and maintenance resources?
In addition to the necessary software and tools, there are some other useful network operation and maintenance resources that can help operation and maintenance personnel better manage and maintain the network. Here are some common network operations resources:
Online communities and forums: Join online communities and forums related to network operation and maintenance to exchange experiences and solve problems with other operation and maintenance personnel.
