I hope this blog post provided some useful Linux tricks that will make your life easier. If you have other Linux command line utilities in your toolbox, please feel free to share them in the comment section below. You can choose between TCP or UDP traffic and set the destination port, bandwidth rate (if UDP is selected), DSCP marking, and TCP window size. The UDP iperf test can also be used to generate multicast traffic and test your PIM infrastructure. Tcpdump is a great utility to troubleshoot network and application issues. For example, at remote sites connected with IPsec tunnels back to the main site, I was often able to figure out why some applications would make it through the tunnel and some wouldn’t.
Fedora is an open-source distribution that serves as a community equivalent to Red Hat Enterprise Linux (RHEL). RHEL itself is commonly chosen as the operating system for enterprise-level systems.

These include multiple SDN courses and HP ASE certification courses (4 day Instructor led training). 2) Network Automation tools such as Ansible don’t run the command node on Windows. You can pick between TCP or UDP traffic and set the destination port, bandwidth rate (if UDP is selected), DSCP marking, and TCP window size.
Specifically, I noticed that applications using the entire IP payload and also enabling the DF (don’t fragment) setting, would fail. This website is using a security service to protect itself from online attacks. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. Get ready with one of these options and in the next post we’ll talk how to access your Linux box remotely and without a password (but securely) with ssh. The list will keep expanding, but for now let’s discuss how you can get your hands on a Linux box with as little cost as possible. There are a few free options if you are comfortable with working on the cloud.
Linux Security and Hardening, The Practical Security Guide
Knowing which TCP/IP ports of a host are listening for incoming connections is crucial, especially when you’re hardening a server or locking down network equipment. Nmap allows you to quickly verify that; just run the Nmap command followed by the hostname or fully qualified domain name. In this series of posts we will try to make a smooth introduction to Linux for network engineers that have zero to very little knowledge of Linux. The monetary investment will be of minimal cost to you since you will only need to spend $60 (at most) to buy a Raspberry Pi (this includes the board, power supply, SD card, enclosure).

Learn how to configure Linux networking, how to create users and assign permissions, how to install and run Linux services such as DNS and DHCP. 1) A lot of network operating systems are based on Linux, or have a Linux shell you can access, or use Linux type commands. As it is a lightweight Linux distro, it works effortlessly even on older computers and laptops.
How Data Center Infrastructures Must Change to Support AI
If you happen to have an old laptop collecting dust, you can install Linux on that and avoid buying any additional hardware. While some Linux distributions are better suited to network engineers, almost any Linux distribution can be used with the right software and configurations. Not all of the software packaged with Kali Linux is useful for network engineers, but luckily, new Kali installations are completely customizable. You should plan out what packages you intend to use in advance so that you can avoid installing useless packages and keep your Kali system minimally cluttered.
With iperf you can also generate multicast traffic and test your PIM infrastructure. When I was a computer science student I spent a lot of time playing around with Linux. My home network was routed by a Pentium 2 workstation running linux network engineer Slackware and configured with IP forwarding and IP tables. In 2003, I attended a CCNA boot camp; the other students and I practiced routing protocols (RIP and OSPF) by building an overlay point-to-point network between our houses.
