Best Linux Command-Line Tools For Network Engineers

Instead of going one by one, which generally would take a long time, you can apply a new configuration or changes to multiple devices. SolarWinds Network Automation Manager is an integrated network automation tool designed for highly scalable or enterprise networks. Other routine tasks – Network automation tools can also schedule automatic network config backups and scans.

If you think we missed any important commands, let us know in the comments section. To capture packets on all the interfaces, use the any flag as shown below. Use the following command to list all the interfaces. To check port connectivity using telnet, use the following command. The telnet command is used to troubleshoot the TCP connections on a port.

Scanning results can be saved to CSV, TXT, XML or IP-Port list files. When I worked full-time as a network engineer, my Linux skills helped me with the tasks of design, implementation, and support of enterprise networks. Here is a list of some of the command-line utilities I recommend to network engineers. Network information can be obtained using utilities such as ping, finger, traceroute, host, dig, nslookup etc.

This job requires you to want to automate and/or standardize network configuration management. You will make use of open-source platforms and tools where possible. A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands. The author shows you an example using Cisco, Arista, and Cumulus Linux.

Network Scanning and Performance Analysis Tools

Tools such as Ansible, Netmiko, NAPALM, and others are well used and maintained on Linux linux network engineer operating system. Install and configure RPM-based and Debian-based distributions.

• A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands.
• Wireshark is an unparalleled network protocol analyzer, and honestly, one of the best free network tools ever made.
• This can also help us to find devices that have mistakenly been configured with incorrect or duplicate IPs.
• You must have a feature rich terminal software for SSH or Telnet.
• While many monitoring systems separate network performance monitoring and server monitoring out into two separate packages, OpManager combines the two in one purchase.

Traceroute can also help to diagnose routing issues, especially when we have more than one network connection to the outside world. A network or system administrator needs to have the right skills required to manage and maintain a network.
