While TCP controls the movement of packets across a network, IP controls the movement of packets across the internet. It’s like having a wider, longer, and more travelled super highway… called the internet. In the case of the IP you have a wider area (the Internet) to transmit packets. Internet Protocol is commonly referred to by its acronym, IP. This is why the protocol is called Transmission Control Protocol (TCP). It also controls network traffic and directs the transmission of packets of information (like folders of data moving from one place to another). TCP directs the Linux operating system on how packets should move from one place to another. See below for an explanation of various tools, including the Linux tool called Traffic Control (tc). Transmission Control Protocol, more often referred to as TCP, is a protocol used for the transmission of packets, just as the name describes. The two protocols that are primary to this article are TCP and IP. There are many different protocols to consider when discussing Linux.

In cases where “sudo” is used and prepended to the command, Linux will request the su password in order to authenticate the superuser identity and permissions. That’s because many of these utilities and apps are sensitive enough that they’re restricted for security reasons.Īn alternative solution to logging in as root or triggering superuser access (su) is to prepend a command with “sudo” telling the Linux machine that that particular command needs to be run as superuser/root, but that subsequent commands do not (unless also prepended with the “sudo” directive). Root Access on a Linux Server (and su and sudo)įor many of the tasks that need to be completed, root access (a.k.a. Just as we generally have a different first name compared to our last name, the IPv4 “name” will be different from the IPv6 “name” even though they both point to the same machine.Ĭarla Schroeder has written an easy-to read and useful article about IPv4 and IPv6. Both names point to the same person (or in this case, a computer).

One is like the first name and the other is the last name. So what are the differences between IPv4 and IPv6? Think of it like a network name. The bottom line is this: If you can’t find what you need, try using different combinations until you get the desired man page.

When you type that particular phrase, you’ll see the correct man page for replacing the ARP man page (or replacing the ARP protocol). You might try typing “ man ip-neighbour” (note the British spelling). You could add a dash (even though that isn’t what shows in the man page when referencing the replacement tool)… So, if you add a dash and type “man ip-neigh” that also works fine but it isn’t correct either. While it’s true that you’ll get a man page if you type “man ip neigh,” unless you are paying close attention, you may miss that it’s not actually what you were looking for. Instead, it’ll look up two man pages… one for “ip” and the other for “neigh.” However, typing “ man ip neigh” does not look up the man page for “ip neigh”. It would seem, by that notation, that one may want to type “ man ip neigh” to access information about the replacement tool/protocol. In the image below, the man page for ARP indicates that ARP is obsolete (under the “notes” section) and that one should look up ip neigh instead. Let’s illustrate those caveat(s) via images. Man pages are easy to use and accurate, but there are a couple of caveats. For example, if you are logged into a Linux server that’s 10 years old, the man page displays information relative to that version (and age).

If there’s no man page for a particular topic Linux will tell you that.įor the most part, man pages are reasonably accurate for the software version on which they appear. Just start typing a couple of words and the Linux OS will begin returning the information to you.

You will learn how to do this later in this article. If you pick a topic you want to research, like a Linux utility, tool, daemon, script, you can look that up by typing “man” and then the word. Those resources are known as, “man pages.” When you are logged into a Linux server (or Linux-based operating system), you can open the command-line application and type in what you would like to research, like typing in a search term in an interactive documentation file. Much like Google, Linux has its own set of search and research tools that enable users to find the resources they need. Man Pages – Information at Your Fingertips The result of these parallel innovations is that once you learn how to perform installations on one server via the command line, you’ve learned a skill that’s likely compatible with many other tasks on a variety of Unix or Linux servers.
