FTP From The Linux Terminal

Why would you want to use FTP from the Linux terminal? It’s quick, easy, consistent, and works well enough as an FTP client. If it’s not already installed, it’s just a quick installation command away. In my experience, it’s usually already there.

If I’m going to be transferring a bunch of files or editing files, I’ll just use a GUI FTP client. My choice FTP client has been Filezilla for quite a long time now. It does the trick and I just keep moving my profile/config to new computers as I get them. Being easy to migrate is a definite selling point for me.

So, what is FTP? It stands for File Transfer Protocol. It’s not encrypted, so many folks have moved to SFTP – which is actually not related to FTP at all. It just shares similar functionality. Even though FTP traffic isn’t secure, it’s still fairly widely used. 

An FTP server is probably not installed by default on your desktop Linux system. However, I’ve written how to Install An FTP Server With VSFTPD which should get you sorted if you need one.

The application will be using is “FTP” which describes itself like:

ftp — Internet file transfer program

And you may find that your version of terminal-based FTP is maintained by your distro maintainers. The FTP command and flagsr should still be pretty universal throughout. Still, be sure to check the man page – especially if things seem weird.

FTP From The Linux Terminal:

Obviously, this requires an open terminal.

Press CTRL + ALT + T and your terminal should pop right open.

Once you have the terminal open the command is basically this:

You can connect via domain name, hostname, or even IP address. It’ll look like this, or pretty close:

ftp from the terminal
See: You can use FTP from the Linux terminal.

There are many commands available, so you should probably check man ftp to see what’s on offer. We’re just going to cover a few of the more useful commands.

You’ll find that ‘ls’ works to list files, just like you’re used to, as does ‘cd’. If you want to change your local directory, that is your working directory on your machine and not the working directory on the server, you need to use the ‘lcd’ command – like so:

Note: Read More About Paths

After you’ve logged in and learned to navigate, it’s time to do something. If you want to download something, you use the ‘get’ command:

That will download the file from the server to the local directory. To do the opposite, that is upload something from your current local directory, you would use the ‘put’ command, like so:

If you want to get or put more than one file, the commands are ‘mget’ and ‘mput’ respectively. They look like this:

Note: It may give a warning about using passive mode. If that’s the case, add the -p flag to your connection command – like ftp -p hostname.

Just like with your regular terminal file management, you can ‘mkdir’, ‘rmdir’, and even use ‘pwd’ to be reminded of your present working directory. Files can also be deleted with the delete <file_name> command.


And there you have it, an article that explains how to use FTP from the Linux terminal. It is important to note that the FTP command transmits data without encryption. If security is a concern, use SCP or SFTP.

Install And Secure MariaDB In Ubuntu

I’ve recently purchased a couple of new VPSes (spelling?) and so today’s article is about how you install and secure MariaDB. As mentioned before, some articles are just going to be me scratching my own itch. In this case, I have a couple of virtual private servers that are doing nothing more than costing me money. I might as well put them to good use.

So, what is MariaDB? It’s a database management system that’s a fork of MySQL. Oracle purchased Sun Microsystems in early 2010 and MySQL went with it. Quite a few people didn’t trust Oracle’s stewardship of MySQL, they were already known for their own database management system, and so MariaDB was born.

MariaDB is actually a fork of MySQL. MariaDB is also permissively licensed, while the newer MySQL has an enterprise version with proprietary code in it. MariaDB is completely open and works just fine under a number of FOSS licenses.

MariaDB is just as fast, and faster in some operations. It supports the native languages used with databases. It’s well supported with a vast number of installs running some of the largest databases on the planet. MariaDB is one of many MySQL forks, which is to be expected. After all, MySQL was the first of its kinda – a free database management system that was released at a key  point (mid 1990s) of Internet development.

In my observation, and despite all its goodness, MariaDB a testament to exactly how much people dislike and don’t trust Oracle! So, then, why not…

Install And Secure MariaDB:

As this is server related, you’re likely to be doing this in a terminal and you’re likely to be using SSH to do so. So, I’m going to assume you already have a terminal open, saving us some time.

Make sure you’re fully updated before attempting this, so:

Now, we’ll go about installing MariaDB. It’s trivial, just run:

That’ll take a minute and, when done, you can verify that the MariaDB service is up and running properly. That needs this command:

MariaDB should be installed and running – but it’s woefully insecure. In order to secure the MariaDB installation, you will want to run the following command:

It’s going to first ask you for your root password. You’ll enter your default root (sudo) password. One of the questions will let you assign a different password for MariaDB and it’s strongly recommended that you do so. For the other few questions, you can read them or you can just answer yes to all of them, as all of them are the best choices for securing your databases.

That’s actually all there is to it. You’ve learned to install and secure MariaDB. It’s one of the many steps you might take if you wanted to set up your own server, so be careful when you’re doing so and opt for the best practices.


There you have it! It’s another article, this one tells you how to install and secure MariaDB. In some cases, rare cases indeed, you might want to open it up to connections outside of localhost. If you do that, be sure to open up the correct port in the firewall. Other than that, you’re good to go.

Guest Article: Kickstart Vol. III

Today is the third guest article in a row, and is one more article about Kickstart. There will be more Kickstart articles, but we’ll release those in time. This is the third one in a row, so we’ll try to mix it up a bit.

By now, we should all have at least a little familiarity with Kickstart. Frankly, I’ve still not had a chance to use it – but it does seem like it’d be fun to play around with it. If I were an admin of anything major, I’d definitely look to Kickstart as a solution. Again, if you read this on day one, be sure to check back later as the author may suggest some edits.

See the previous articles here:

Guest Article: Kickstart Vol. I
Guest Article: Kickstart Vol. II

Kickstart Vol. III

Now we need to create a menu for your Kickstart, so you can select which OS you want to install.

Now edit a new file named grub.cfg. It must be named grub.cfg. Here is an example of what it should look like.

The set-default lets you pick which is the default install, it starts at zero, so the options here would be 0, 1 and 2.

Note the IP address of my Kickstart server is here, the path to my extracted iso directory is here, and the location of my boot kernels is here.You can change all of these to fit your needs.

Now we need the actual anaconda-kickstart.cfg files, this is what actually does all the work.The location of these, is set in the grub.cfg file above. You will want these to be in the extracted iso directory, but not in the “dvd” sub-directory.

Here is an example of what one of these would look like. This one is fairly basic.

Again you see the IP address of my kickstart server here, you see the location of my extracted iso files here.Now there are a few things you will need to know in advance.

What I typically do, is install the OS from a USB the first time.In the case of fedora/redhat/CentOS there will be a file at /root/anaconda.cfg. You can copy this file as a starting template for your kickstart of this OS.

(Yes I am re-naming the file here.)

Also you will need the password has strings for your users.

(Or whatever user name you use.)

You will need to know the name of the LAN interface, and you will need to know the size of your hard, and how big the partitions should be.All of these things will be in your anaconda.cfg file

Now change and edit a few things in your fed35srv/fed35.cfg file now.

Change the graphical install to..testskipx This uses a cli interface, not a GUI when installing.

Change the url line to the location of your extracted iso directory in your web server. Note you don’t put the full path, only the path from your webroot.

I like to turn off seLinux, but you can delete that line if you like.

Change your timezone to whatever is appropriate for you.

Using the two example user lines above (those aren’t real hashes, I just typed a bunch of random characters to simulate what it looks like). Edit the user lines to be whatever your values are.

That’s it, you’re don! Now boot your test computer on the kickstart network. A Kickstart menu should appear. Select the appropriate OS.

I’ve found this usually works best with a few settings on the test computer. CSM should be disabled. Network stack should be enabled. Some UEFI settings let you pick PXEboot IPv4 as a boot option. This is preferred. I’ve found it works best with a freshly formatted hard-drive, that way it doesn’t try to boot into the installed OS.

Good luck!


And there you have it! You have a guest article, from dos2unix, about Kickstart. There are now three of them and there are a couple of others sitting in the potential queue. We’ll get to them. These few days off have been a very welcomed respite!

Guest Article: Kickstart Vol. I

This is an article about Kickstart written by guest author, dos2unix from the Linux.org Forum. It’s the first of a few articles from them, so let’s give them a warm welcome and enjoy their article!

Kickstart Vol. I

Kickstart is really Redhat/CentOS/Fedora-centric. There are some attempts for parts of this work on Ubuntu and SuSE, but so far there is really little support for this. Kickstart does a lot of the mundane work for you. It sets up the filesystems for you, you control this size and format of them. It creates user accounts for you, sets up your network for you, and installs the packages you want to be installed (or not installed). You can even run a shell script automatically when everything is done.

Now if you only have one computer, and you only install the OS once a year, this isn’t going to save you much time. However if you have quite a few computers, for example a data-center with dozens or hundreds of servers. Or even a few test systems that have to be rebuilt every day or every few days. Then this can save you a lot of time.

The Kickstart computer itself doesn’t have to be anything fancy. In fact, it doesn’t even have to run one of Redhat type OS’s listed above. It can be Debian, Ubuntu, or whatever you like. It’s best if it has two LAN (Ethernet) interfaces. Most computers cannot be Kickstarted over WiFi yet. You can use a single network interface, but it makes things a little more difficult. If you have a lot of computers to Kickstart, I recommend that you get a small un-managed switch. 5 or 8 ports should be plenty, unless you’re at a data-center.I have worked in data-centers, but now I work at a place that writes software, and we test it over and over again, so I have to “rebuild” the OS sometimes several times a day.

Obviously you’ll need a computer to do this. If possible you’ll want a second computer to test on. One that will be the computer that’s being “Kickstarted”. You’ll need about 20 GB of free space on your Kickstart server to install .ISO images of the OS(es) you want to install.

Your Kickstart server will need three items installed. There are multiple ways to do this. We will discuss a couple of the most common ones. Perhaps a follow-up article will offer more options if there is enough interest.

First you need a web server like Apache httpd, or NGINX, you could even use the simple Python web-server, it doesn’t matter that much.

Second you’ll need a DHCP server, again you could use either BIND or dnsmasq, we will discuss both ways. Finally you’ll need a tftp server. If you use dnsmasq,it has a tftp server of sorts built-in.

It’s beyond the scope of this article to teach you how to install these items, it is assumed you already know how to install software.Note that this will have to be on a different network that your normal home/work/datacenter network.

You don’t want Kickstart erasing, wiping out, and re-installing the OS’s on your every day driver. This is why I recommend one with two interfaces. Otherwise, you’ll have to re-configure your network to download packages, install updates,and add more packages if necessary, and then re-configure it back to your Kickstart network. That gets old in a hurry, trust me.

I’m using Fedora as my Kickstart server. I currently have configurations to install Redhat 8, Redhat 9, CentOS 8, Fedora 33, Fedora 34, and Fedora 35. I install all of these on 3 different computer hardware types. You don’t have to install the same OS that your Kickstart server is running. For this first example, I’m going to use NGINX as my web server, dhcpd (BIND) as my DHCP server, and tftp-server, as well… My tftp server. My Kickstart has two LAN interfaces, it doesn’t really matter too much how you have the first interface configured.

Again, it’s beyond the scope of this article to tell you how to configure your network interfaces, it is assumed you already know how to do this. You’ll want a static IP on your second interface.A gateway isn’t required, for this article, we can just, try to pick something obscure that no one else will use in the environment you are in. I will go ahead a use a /24 subnet or for those who aren’t familiar with CIDR subnet masks.

Remember this IP address, it will be used in quite a configuration files. Again you can use any IP you like,but remember what it is, because you’ll need it several times.

So for Fedora, it’s a simple dnf install -y nginx dhcpd-server tftp-server, other OS’es may vary.

Once they are installed we will need to configure them.

The first one here is NGINX. On most Linux’s I have used, the nginx.conf file is located in /etc/nginx/nginx.conf. You have a “server section” in this file.It’ll say server with a { after it. Replace the contents of your server section with the content below. This assumes your web content will be at /usr/share/nginx/html you can adjust this accordingly. This will be where your extracted .iso images will live. So make sure you have space here (or do a soft link to another directory that has space). You can use SSL/HTTPS, but again that’s beyond the scope of this article.

I also recommend adding these two lines, below your access_log section. The other lines will likely already be there.

access_log /var/log/nginx/access.log main;

Now enable and start your web server. For Fedora it’s 
systemctl enable nginx
systemctl start nginx

Now we need to configure your DHCP server. For BIND (dhcpd) the conf file is usually located at /etc/dhcp/dhcpd.conf (not to be confused with dhcpd6.conf )

Just mv the dhcpd.conf to something like dhcpd.conf-original or whatever you like, just make sure it doesn’t end with “.conf”. Now make a new files and copy the following to it.

I’m using the entire 192.168.7.x subnet here. The IP address of my Kickstart server is this file and replace the values of your server/network accordingly. The range tells my DHCP server to only give out IP addresses between 10 and 120.

Now you may be wondering about that last line, what is the “next-server” and why does it have the same IP address as my Kickstart/DHCP server? The “next server” after I receive a DHCP address is the tftp server, it’s located at the same IP address. You could run it on a different server, but most people run it on the same server.

Again just like NGINX, let us enable and start the service.
systemctl enable dhcpdsystemctl start dhcpd

For the tftp server, you really don’t have to do much, by default tftp wants tftpboot to be at /var/lib , so…

Note this is a listening socket, not really a server per se.If you want to make sure that your tftp server if pointing to /var/lib/tftpboot you can run..
systemctl cat tftp.service

You should see a line like this somewhere:

ExecStart=/usr/sbin/in.tftpd -s /var/lib/tftpboot

I would recommend not changing this, as several configuration files will like in this directory.


Honestly, I edited the above the best that I could – given that I know nothing about the subject. I appreciate the articles, but it means trusting dos2unix – and I’m perfectly willing to do that. If you have any questions, you can post them here or you can post them on the linux.org forum where I share this article (as that’s where dos2unix lives).

Either way, stay tuned – as this is just the first part of a series of articles handily written on this subject. I, for one, am going to probably use the break to get a few articles ahead so that the new year starts off right.

How To: Start A Quick Python Server

Today’s article is going to show you how to transfer files between computers by using a quick Python server. It’s remarkably easy! It’s a temporary server (usually) and lasts only as long as you need it to.

Why would you do this? Well, you can transfer files from one computer to another. It also functions as an HTTP server which makes it easy to test things like simple web pages quickly and easily.

Are there better options? Quite probably. If you want to transfer a single file, then SCP is a good way to go about it. If you want to transfer multiple files, you could setup SFTP. If you want to test web pages, you can likely just write the files locally and then open them up with the browser of your choice.

You have options! And, thankfully, Linux provides all sorts of options – including setting up a quick Python server. As I said, it’s actually pretty easy.

A Quick Python Server:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

The first command I want you to run will let us know what version of Python you have installed. Many distros have (at present) moved onto version 3, but some still have Python 2 installed. So, for that information you just run:

Now, if you have Python v. 2.x, you would use this command:

If you’re using Python v. 3.x then the command you’d use is:

(If you’re curious, the -m is telling Python which module to open.)

Anyhow,  you can now connect to your server with the following command:

Read how to find your IP address. Instead of an IP address, you can also use your hostname.

Anyhow, you  now have a server running on port 8000. If you want to, you can also change the port number. This is the same for both commands. In both cases, just append your chosen port number to the command. Like this:

It’d look a little like this:

See? It's a different port number.
Note the changed port number. You should probably avoid reserved ports.

When you’re done with the quick Python server, you can just close it by pressing CTRL + C. If you’re planning on running it long term, you can always run the command with nohup. If applicable, you may also need to open the port in your firewall.

Like I said, it’s a quick and easy server in Python. You definitely wouldn’t want to use this as a public facing server, but it’s fine for quick tasks. Feel free to leave a comment letting folks know how you use this in  your day-to-day tasks.


There you have it, another article said and done! The site is going well and the schedule seems to be working well enough. It’s a bit demanding to write one every other day, but that’s what I said I’d try to do. So far, so good!
