How FTP works.

FTP is based on a client-server configuration. Therefore, it allows you to transmit information regardless of the operating system you use. Even the system used by the hosting provider (Windows, Linux, MAC, etc.) is not relevant. To be able to use it, it is necessary to have a server and also a client. Check our tutorials to learn more about each type.

The communication is initiated when a connection is made from the client to the server. In addition, this connection is negotiated through the network port 21, also called control port. However, this will not be the port through which the information will be sent or downloaded. Indeed, this depends on the FTP mode selected.

FTP modes

Active mode: the server opens the initial connection. Consequently, it opens the connection on its port 20 and connects to the client on a random port greater than 1024. Moreover, this port is specified by the FTP client itself. Note that this is the least recommended option. Indeed, its use implies having a fairly wide range of ports open on your computer. It certainly carries many security risks.

Passive mode: the client opens the initial connection. In addition, it is the server that indicates which port to open. It will always be done on a network port greater than 1024 of the servers. Therefore, it is not necessary to have open ports on the computer. This is logical, since it will be the server that will open the connection.

We have already mentioned that the FT protocol was created several years ago. Even before hackers existed. Therefore, it was not recognized as a secure protocol. In fact, the information that travels between computer and server is in plain text. That is, without any kind of encryption.

What does the lack of encryption imply?

Well, this implies a considerable risk that the data will be captured. Indeed, an attacker could see our connection data and even view the information we are uploading. Even worse, they could download it using a Sniffer type software. These tools are capable of scanning the network for vulnerabilities.

Suppose you make a connection using plain FTP. As a result, you will see a warning that the connection is not secure. We have established that the FTP connection is not secure at all. Because of this, two secure versions were subsequently born: FTPS and SFTP. Although they are almost the same acronym, they are not at all the same. Let’s take a look at what each one consists of.

Secure versions of FTP: FTPS and SFTP

What is FTPS?

FTPS works in the same way as conventional FTP. However, the main difference is that it has an SSL/TLS encryption layer underneath. Also, this layer is provided by a security certificate. It is known as Secure FTP and there are two types of connection:

• Explicit FTPS: This is the month used. In addition, we also recommend its use. A normal, unencrypted connection is made. However, before sending any sensitive data, TLS negotiation is required to encrypt the connection.
• Implicit FTPS: It is in disuse. In fact, it is not available on most servers. The negotiation of the secure connection is done before any FTP command is sent.

What is SFTP?

SFTP is a wholly different protocol from conventional FTP. Indeed, it is based on the SSH (Secure Shell) protocol. In addition, the entire connection is encrypted and made through network port 22. They differ not only in encryption. Additionally, it is a protocol with more functionalities than conventional FTP. For example, we have the execution of CLI (Command Line Interface) commands.

SFTP stands for Secure File Transfer Protocol. Through it, we can exchange encrypted data between the client and the server. It uses Secure Shell (SSH) for this purpose. In addition, we can not only transfer files via SFTP. Indeed, we can view directories, rename them or limit rights. An SFTP program allows you to upload files for your website to your webspace. We can even create a backup of the website with SFTP. With a SFTP program, you can also delete entire files and folders. Indeed, if you delete contents, they will no longer appear to visitors of your website. In short, SFTP is the successor to FTP. The major difference is greater security. This is indicated by the addition Secure.

Conclusion

Security is a fundamental concern in any technology environment. Certainly, in the world of hosting, it is an element that also depends on the provider. However, it is primarily an element to be taken care of by the user. Today we talked about the differences between FTP and SFTP. Logically, you may have noticed that the main difference is related to security. Therefore, it is not currently recommended using a conventional FTP connection to connect. There are certainly exceptions. For example, we can use them for specific cases for reasons of urgency. Mostly when we need a fast connection and do not have much time to configure it. Moreover, when the data to be shared is not sensitive.

Consequently, when you connect via FTP to upload or download data, remember to always do it via FTPS or SFTP. This way, we are taking care of our data. Please keep in mind that hackers are always on the prowl. Therefore, it is our duty to make things more difficult for them. See you soon!

What is an FTP server

The first thing we will do is to define what an FTP server is. It is a service used to transfer files. That is, to upload and download data between two remotely connected computers. Usually, it is between a client’s local computer and a provider’s server. For this to be possible, it is necessary to have an FTP client and an FTP server. It is actually the software that allows the transfer of files between two computers. Note that the connection is bidirectional. That is, we can receive and send data at the same time. In addition, we can upload all kinds of files. For example, you can upload images, video files, text documents, etc.

We can increase the security of the service by using username and password. This allows us to authenticate ourselves. In addition to verify a specific account to access a server and transfer files. However, it is also possible to access as a guest, which could be anonymous.

How to use Google Drive as an FTP server. Step by step.

We have briefly explained what the FTP protocol is and how the client and server work. Now we are going to explain how we can use Google Drive for it. With this in mind, we will use google-drive-ftp-adapter, which is the application needed to achieve this. In addition, we will have to download it to our computer and configure it. Finally, we will start using it with our user to start uploading and downloading files.

Download google-drive-ftp-adapter

Logically, the first thing you have to do is to download google-drive-ftp-adapter. This is a free, open-source software, and we can download it from GitHub. Kindly note that it is imperative to have Java installed for it to work flawlessly. In the GitHub page we will see all the information related to the project. Previously, we had to download the ZIP file and from there look for the files needed to run. However, the author has simplified the download and use of the tool. In fact, it has brought together, in a single file, the tool itself together with its dependencies. Therefore, you only have to scroll down and download the file that I indicate in the following image:

It is likely that the system will warn you about the alleged dangerousness of the download. Please be advised that you can download without any problems. It is actually a false positive. The tool is perfectly safe and harmless to system security. It simply fulfills its mission of using Google Drive as an FTP server. Undoubtedly, it widens even more the range of possibilities of this cloud storage service.

Execute the jar file

We have mentioned that the procedure has been modernized. Previously you had to download the ZIP file. Then you had to unzip it. Then go to the google-drive-ftp-adapter-master folder. And from there, run the homonymous jar file. It was certainly a bit more tedious. However, the methodology has been simplified to the extreme. In fact, you just have to double-click on the google-drive-ftp-adapter-jar-with-dependencies.jar file.

As mentioned above, it is likely that the execution of the file will throw an error. This error occurs because the system detects it as potentially dangerous. But we have already told you that it is perfectly safe. So if it says that it cannot be read or executed, don’t worry. Just run it again. Most likely it will run without problems.

Linking Google Drive account

We are going to work with Google Drive. Therefore, it is necessary to add our user credentials. Don’t worry, this is something that the program handles automatically. Once we double-click on the file, we will be redirected to the Google Drive website. Please log in. Furthermore, we have to give the necessary permissions for it to work properly.

It is necessary to grant the necessary permissions for the program to work correctly. In addition, Windows Defender is likely to display a warning message. You have to accept it, otherwise the program is likely to have problems. Similarly, access to the Google Drive account with username and password is essential. In this way, we can access the content we have already saved or upload new files we want to the platform.

From this point on, Google Drive is already configured as an FTP server. The best thing is that the tool automates the whole process. From now on, we only need an FTP client. In this case, we will use WinSCP, which works very well. However, the process is the same with any other client. Have a look at this list of FTP clients we prepared for you.

Configuring the FTP client.

The configuration is elementary, you only have to add some data to be able to connect to Google Drive. We have to put in host name Localhost. In the user section we put user and password also user. Regarding the port we will use, we put 1821. This is the port that google-drive-ftp-adapter configures by default. In the options that will appear above, we have to select FTP and without encryption.

All that remains is to press the connect button. Please wait a few seconds while the tool synchronizes. As a result, we will see all files present in our Google Drive. From now on, we will be able to upload and download data at our convenience. Ultimately, we have seen how to use Google Drive as an FTP server. Another use you may not have known about for this popular storage service. See you later!

FileZilla

FileZilla is one of the most popular FTP applications. It is a free, open-source, cross-platform program. Its main advantage is that files are easily exchanged as soon as the connection is established. It also allows the exchange of large files. Additionally, it is possible to resume interrupted transfers. Users can determine the upload and download speed. Furthermore, it is possible to store information from the FTP server. Optionally it is possible to enable SSL / TLS or SSH protocol.

WISE-FTP

WISE-FTP is a paid FTP program for Windows operating systems. However, it offers a 30-day free trial period. The software supports all common protocols such as FTP, SFTP, FTPS, or FTPES. Therefore, it allows connection to any FTP server. It even allows you to fully automate the file transfer process. Simply name a target server and establish when and how often an activity is to be executed. Both authentication and file transmission are highly secure thanks to the SFTP or FTPS protocols. In addition, data can be encrypted using various protocols. For example, Rijndael, BlowFish, or TripleDES. Without any doubt, it is solution-oriented for professional use.

Cyberduck

This is a free FTP client, available for Windows and macOS. It easily connects to FTP, SFTP, WebDAV servers. It also enables connection to cloud storage services such as Amazon S3, Azure, or OpenStack. The user interface is intuitive and user-friendly. As an advantage, it allows you to add a new server quickly. In addition, it is possible to limit the number of simultaneous transfers. It is also possible to resume interrupted transfers. This open-source program allows organizing bookmarks. They can be imported from other programs.

SmartFTP

This FTP client is paid. However, it is possible to test it for 30 days. It supports FTP, FTPS, and SFTP protocols. Additionally, it allows connection to services such as WebDAV, Amazon S3, Google Drive, and Microsoft OneDrive. It also allows connection to multiple servers. Therefore, data can be moved from one server to another via FXP. The integrated search function is a great advantage for large FTP servers. All in all, if you are looking for a professional option, then it is worth the price.

WinSCP

WinSCP is open-source software for Windows. It supports several protocols, such as FTP, SFTP, and the SCP security protocol. When connecting to an SSH server, users enjoy encrypted data exchange. In addition to encrypting access data. WinSCP allows synchronizing directories and copying, moving, or deleting files. In addition, it is possible to choose between two program interfaces. It is also possible to bookmark frequently used links as favorites.

Very well, at the end of the day, we have seen the best FTP clients for Windows. Of course, there are other options available. However, we believe these are the best. In addition, there are free and paid options. Okay, that’s it for now. See you later.

The post The best FTP clients for Windows. appeared first on Linux Windows and android Tutorials.

The File Transfer Protocol is a protocol that allows two remote computers to share files over a network. Usually, this happens from a server computer to a client computer. Usually, this happens through ports 20 and 21

Companies that have an intranet for daily work, usually have an FTP server configured to make files available to everyone and in Ubuntu 20.04 it is easy to do so.

Creating an FTP server on Ubuntu 20.04

Several daemons allow you to create the FTP server, however, I consider the easiest and fastest to VSFTPD. Besides all this, it works without problems and without making too many strange configurations.

So, open a terminal and update the system.

:~$ sudo apt update
:~$ sudo apt upgrade

And now, install the VSFTPD daemon.

:~$ sudo apt install vsftpd
Reading package lists… Done
Building dependency tree
Reading state information… Done
The following additional packages will be installed:

0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 132 kB of archives.
After this operation, 402 kB of additional disk space will be used.
Do you want to continue? [Y/n

Like all services in Debian, it will start by default. To see if it is running correctly, use systemctl.

:~$ sudo systemctl status vsftpd
● vsftpd.service - vsftpd FTP server
Loaded: loaded (/lib/systemd/system/vsftpd.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2020-05-17 02:34:40 UTC; 1min 17s ago
Main PID: 1337 (vsftpd)
Tasks: 1 (limit: 506)
Memory: 844.0K
CGroup: /system.slice/vsftpd.service
└─1337 /usr/sbin/vsftpd /etc/vsftpd.conf
May 17 02:34:40 osradar systemd[1]: Starting vsftpd FTP server…
May 17 02:34:40 osradar systemd[1]: Started vsftpd FTP server.

The demon already has a default configuration, but we have to modify it to our liking.

Let’s go for it.

Configuring the FTP server

All the VSFTPD configuration is in the /etc/vsftpd.conf file, so before modifying it is convenient to make a backup of it. In case something goes wrong, we can go back to the original and reverse any wrong we have done.

:~$ sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak

If you display the contents of the file, you will see that it is very extensive. But that’s because it’s so well documented, it’s quite easy to understand.

Let’s start by having the server actively listen.

listen=YES

If you are not going to use IPv6 then you should disable the support:

listen_ipv6=NO

It is also not advisable to allow access to anonymous. Although sometimes it can be useful.

anonymous_enable=NO

By default, on an FTP server, a client can only download files and not upload them. However, it is a good idea to leave it active.

local_enable=YES
write_enable=YES

By default, FTP works by 20.

connect_from_port_20=YES

Although you can change it with this directive:

listen_port=XX

You can use the key combination CTRL + W to go directly to the line you are looking for.

When you are ready, save your changes with CTRL + O and close the file with CTRL + X.

Omitting the comments in the file should look like this:

listen=YES
listen_ipv6=NO
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
ssl_enable=NO

To display the file without the comments, run the following command:

:~$ sudo cat /etc/vsftpd.conf | grep -v "^#"

Creating a new FTP user

Now there is a new user for the FTP server. This user can be created from the same terminal.

:~$ sudo useradd -m user1

And then, assign him a password:

:~$ sudo passwd user1

So,now we can test the new FTP server on Ubuntu 20.04.

Testing the FTP server on Ubuntu 20.04

Now the moment of truth has arrived. Let’s try the FTP server.

One way is to open a terminal and try to access it with the ftp command and the server’s IP address.

:~$ ftp 192.168.250.20
Connected to 192.168.250.20.
220 (vsFTPd 3.0.3)
Name (192.168.250.20:angelo): user1
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp>

Once the connection to the server is established, you will be asked for the username and password.

If the login is correct you will already have access to download and upload files.

Another way is from the web browser of your preference to access the FTP server. In my case, I access the following address ftp://192.168.250.20 and it is required immediately to log in.

By writing correctly the credentials created, I can access the folder that this user has dedicated.

To take better advantage of FTP, it is convenient to install a tool such as Filezilla.

So, that’s it. The FTP server is alive.

Conclusion

An FTP server can be a great way to share files on a network. Especially if it’s for an organization or on an intranet. You saw that setting one up in Ubuntu 20.04 is a pretty simple thing.

Set up vsftpd on FreeBSD 12

Before starting with this installation, it is convenient to have sudo enabled for your regular user. It is not mandatory, but this will avoid working directly with the root user.

So, read our post about it:

How to enable sudo on FreeBSD 12?

We will also have to install the nano text editor to make file editing easier:

:~$ sudo pkg install nano

With this, we’ll be able to work quietly.

1.- Install vsftpd on FreeBSD 12

First, you need to install vvsftpd on FreeBSD 12.

So, open the terminal and navigate to the folder where the port is.

:~$ cd /usr/ports/ftp/vsftp

Then, install it with the following command:

:~$ sudo make install clean

During the installation process, you will see a screen as in the image above. You can leave everything as it is.

At the end of the installation, you will see an image similar to this:

Now install another port to increase the security of vsftpd.

:~$ cd /usr/ports/security/pam_pwdfile
:~$ sudo make install clean
===>  Staging for pam_pwdfile-1.0
===>   Generating temporary packing list
install  -s -o root -g wheel -m 444   -S  pam_pwdfile.so /usr/ports/security/pam_pwdfile/work/stage/usr/local/lib/
====> Compressing man pages (compress-man)
===>  Installing for pam_pwdfile-1.0
===>  Checking if pam_pwdfile is already installed
===>   Registering installation for pam_pwdfile-1.0
Installing pam_pwdfile-1.0...
===>  Cleaning for pam_pwdfile-1.0

As in the vsftpd installation, you will see an image where you can add a feature or not. Just keep it as it is.

To authenticate vsftpd users correctly, we have to add some lines to a pam.d configuration file

:~$ sudo nano /etc/pam.d/vsftpd
auth required /usr/local/lib/pam_pwdfile.so pwdfile /usr/local/etc/vsftpd_login.db
account required /usr/lib/pam_permit.so

Save the changes and close the file.

2.- Configuring vsftpd to work properly

Once vsftpd is installed, you have to make settings so you can start and work properly.

First of all, you have to create a new user on the system so you can use the server.

:~$ sudo adduser -v

And then, complete the information with the values you want.

Username: angeloftp
Full name: angelo
Uid (Leave empty for default): 
Login group [angeloftp]: 
Login group is angeloftp. Invite angeloftp into other groups? []: 
Login class [default]: 
Shell (sh csh tcsh nologin) [sh]: nologin
Home directory [/home/angeloftp]: 
Home directory permissions (Leave empty for default): 
Use password-based authentication? [yes]: 
Use an empty password? (yes/no) [no]: 
Use a random password? (yes/no) [no]: 
Enter password: 
Enter password again: 
Lock out the account after creation? [no]: 
Username   : angeloftp
Password   : *****
Full Name  : angelo
Uid        : 1003
Class      : 
Groups     : angeloftp 
Home       : /home/angeloftp
Home Mode  : 
Shell      : /usr/sbin/nologin
Locked     : no
OK? (yes/no): yes
adduser: INFO: Successfully added (angeloftp) to the user database.
Add another user? (yes/no): no
Goodbye!

So, you can modify the user and password parameters. The rest you can keep the same.

Now, let’s modify the vsftpd configuration file. In this file are all the settings we can have. Before modifying it, let’s make a backup of it:

:~$ sudo mv /usr/local/etc/vsftpd.conf /usr/local/etc/vsftpd.conf.bak

And now, yes, you proceed to modify it:

:~$ sudo nano /usr/local/etc/vsftpd.conf

In my case, the configuration that works for me without problems is the following:

anonymous_enable=NO
anon_upload_enable=NO
anon_mkdir_write_enable=NO
local_enable=YES
write_enable=YES
listen_port=21
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_file=/var/log/vsftpd.log
xferlog_std_format=YES
secure_chroot_dir=/usr/local/share/vsftpd/empty
max_clients=200
max_per_ip=100
chroot_local_user=YES
text_userdb_names=YES
force_dot_files=NO
anon_root=/home/ftp
async_abor_enable=YES
use_localtime=YES
listen=YES
background=YES
allow_writeable_chroot=YES

Of course, this is an example. You can always explore other options and for that we refer you to the vsftp official documentation.

Again, save the changes and close the file.

Now you have to add users to vsftpd, but first you have to create the file where the users and their passwords will be. To do this, we’ll use a tool called htpasswd. And use this command:

:~$ sudo htpasswd -c -b /usr/local/etc/vsftpd_login.db [username] [password]

Changes the permissions of the created file:

:~$ sudo chmod 0600 /usr/local/etc/vsftpd_login.db

In username and password replace it with the user we created earlier.

In case htpasswd is not available, you can get it by installing the apache web server.

:~$ sudo pkg install apache24
Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
The following 8 package(s) will be affected (of 0 checked):

New packages to be INSTALLED:
	apache24: 2.4.41
	libnghttp2: 1.40.0
	libxml2: 2.9.10
	expat: 2.2.8
	pcre: 8.43_2
	apr: 1.7.0.1.6.1
	gdbm: 1.18.1_1
	db5: 5.3.28_7

Number of packages to be installed: 8

The process will require 92 MiB more space.
20 MiB to be downloaded.

Proceed with this action? [y/N]:

If you want to add new users, you can do it with the following command:

:~$ sudo htpasswd -b /usr/local/etc/vsftpd_login.db USERNAME PASSWORD

Configure vsftpd to start with the system by editing the following file

:~$ sudo nano /etc/rc.conf

And in it he adds the following:

vsftpd_enable="YES"

Finally, the vsftpd service starts.

:~$ sudo /usr/local/etc/rc.d/vsftpd start

Now the creature is alive.

Access to the FTP server

Now that the service is working, we have to test it. Open your favorite web browser and go to ftp://server-ip.

First you will need to enter your username and password and then you will see the following:

You can also use a graphic client on your computer like Filezilla.

Add a new connection and type in your credentials:

After accepting the connection and entering the password, it will connect. And as you can see, everything has been successful:

So, everything’s in order.

Conclusion

An FTP server on FreeBSD can be a secure alternative for sharing files on a network. It is as easy to set up as you have seen it today.

Installing Wget in Windows 10

Wget is a free tool and relatively simple to install in a Linux environment. Just type the appropriate commands to each distribution, and you’re done. However, when it comes to Windows, the situation changes. There are many installers and options that end up with installation errors. However, we’ve got this version that works properly. Go to this link and download version 1.11.4-1

Next, we proceed to run the installer. Just double click and the wizard will start, press next to continue:

Then accept the license terms, and click Next to continue the installation.

Select the folder where the program will be installed. Click next to continue the installation.

Next, select the components to install. To ensure proper operation, check both boxes and press Next to continue the installation.

Next, you can create direct access to the application and its respective location

You can install additional icons. Click Next to continue

Verify the installation options and press Install to finish the process.

Once the installation is finished, we will see the following screen.

Using Wget in Windows 10

Please note that Wget does not have a graphical interface, so you will have to use it through command in the CMD. To check that the program is actually installed, please go to the installation directory. Depending on the installation options selected, it should be as follows:

C:\Program Files (x86)\GnuWin32\bin

What we need to do is open a command prompt. With this intention, press the Win+R combination and type CMD

Once there, use the CD command to navigate to the file location mentioned above. Then type Wget to use the program.

Add environment variable

We have correctly installed Wget. However, to be able to use it we always have to navigate to the installation folder of the program. This is cumbersome, so if we want to use Wget from any directory, we need to add an environment variable. With this in mind, please follow this path: Control Panel>System and Security>System>Advanced system settings

On the next screen, choose Environment Variables

Next, we are going to create a new environment variable. With that intention, please select Path and press Edit.

On the next screen first select New, then Browse. You must select the address where the program is installed.

Press ok in each of the open windows, and we can run Wget every time we open a Command Prompt. It doesn’t matter which directory we’re in. Let’s test the Wget command, downloading its executable for windows 10. With this intention, we enter this command in the CMD

wget https://sourceforge.net/projects/gnuwin32/files/wget/1.11.4-1/wget-1.11.4-1-setup.exe/download

Using Wget in Windows Subsystem for Linux

We have already seen how to use bash in windows 10. Through WSL we can also use Wget natively. To do this, we’ll open ubuntu and run the following command:

 sudo apt-get install wget 

Enter your password, and wait while the program is installed. Now we are ready to use wget in Windows 10.

Finally, we have seen how to install Wget in Windows 10. We can do it natively or using the Windows Subsystem for Linux. Both methods are valid for using this powerful download tool. Not only will we have access to files, but also to complete pages so that they can run offline. All right, that’s it for now, if you have any questions, don’t hesitate to ask. We are here to serve! until next time!

Configuring an FTP Server on Debian 10

First of all, you need root access. Either the user is active and has the password, or your user is enabled to use Sudo.

In any case, we also require you to establish a connection to the Debian server using SSH or locally with a terminal session.

1.- Upgrade the system

Before any installation, the main thing is to update the system. This way it will be safer to continue:

:~$ sudo apt update && sudo apt upgrade

This way your Debian 10 system will have the necessary security patches installed.

2.- Install VSFTPD on Debian 10

Now we will install the FTP daemon that we have chosen. In this case, it is VSFTPD. The advantage of using it is that it is easy to configure and is in the Debian 10 repositories.

:~$ sudo apt install vsftpd

Next, check the service status:

:~$ sudo systemctl status vsftpd

So, the service is running.

3.- Configure the FTP server

The VSFTPD configuration can be found at /etc/vsftpd.conf. Before modifying the contents of the configuration file, it is recommended to make a backup. If something goes wrong we will be able to restore and nothing bad will have happened.

:~$ sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak

Now, we can start with the work.

:~$ sudo nano /etc/vsftpd.conf

The file is somewhat extensive but it is because it is very well documented. The truth is simple to manipulate. First, make the service “listen” and if you don’t use IPV6, disable it.

listen=YES
#listen_ipv6=NO

By default, VSFTPD does not let you change the assigned folder. That is, it will only allow the download but not the upload. If you want to change this, leave the following directive like this:

write_enable=YES

The default port is 20 but you can change it:

#connect_from_port_20=YES
listen_port=21

Here comes a slightly delicate matter. It is normal that when we use an FTP server we have to create users who use it. The problem is that some users can upload and delete files from other users. This should be avoided. It is necessary to define what each user has his folder and that he cannot modify or see the others.

chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list

Now you have to create the file with the list of users. Note that in this step, I have added a user called test1. That is the name of the user I will create later.

:~$ sudo nano /etc/vsftpd.chroot_list
angelo
test1

The pasv_min_port and pasv_max_port directives define the range of ports that will passively work FTP. These ports must be accessible if you use a Firewall.

At the end your configuration file will look like this:

:~$ sudo cat /etc/vsftpd.conf | grep -v "^#"

Next, create the new user:

:~$ sudo adduser test1

Next, reload the VSFTPD service.

:~$ sudo systemctl restart vsftpd

And check the status:

:~$ sudo systemctl status vsftpd

4.- Test the FTP server on Debian 10

Open a web browser and go to ftp://your-server/ and you will see this.

It is anonymous access if you do not want it, open your configuration file and define this:

anonymous_enable=NO

Save the file and restart the service.

So, you can also install Filezilla which is an FTP client.

:~$ sudo apt install filezilla

Once the program is open, go to the File menu. Next, click on the Site Manager option. Then define your configuration:

So, you can enjoy your FTP server on Debian 10.

Configure a FTP server with vsftpd

vsftpd is a daemon that allows you to install and configure an FTP server. It is quite used for being very flexible in its configuration and secure. For example, it is the default in OpenSUSE and CentOS 7 but can be used in almost any Linux distribution.

Its configuration files are quite easy to understand because they are well documented. So this makes it the main option for our purpose.

So let us start.

Install and configure vsftpd on OpenSUSE 15.1

First, we must install it. The big advantage is that vsftpd is in the OpenSUSE repositories so we can install it using zypper.

:~$ sudo zypper in vsftpd

Now comes the configuration for everything to work properly.

The configuration file is this /etc/vsftpd.conf. If you open it you will see that it is very extensive, but it is because it has many commented lines. It is very well documented.

Before we edit it, let’s create a backup.

:~$ sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak

There are several things we need to edit.

:~$ sudo nano /etc/vsftpd.conf

Firstly, we must make the service “listen”. IPV4 and disable IPV6.

listen=YES
#listen_ipv6=NO

Then, allow writing.

write_enable=YES

There is a clause that defines port 20 as the default. I have commented on it and used the listen_port clause to define another port. For example, port 21. It can be the one you want.

#connect_from_port_20=YES
listen_port=21

It is very likely that if you work with FTP you will need to create users. To do this, it is necessary to cage them before creating them. That is to say, that each user cannot upload or download files from other users and even less from the system. In other words, they are isolated to their folder. To do this, add the following lines.

chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list

Then, create the file specified in chroot_list_file and add our system user there

:~$ sudo nano /etc/vsftpd.chroot_list
angelo

The pasv_min_port and pasv_max_port clauses define which ports FTP can use to be in passive mode. You have to work in the Firewall with them.

We can use the grep and cat commands to make the file more readable. With them I will show all the lines except the ones that start with a #.

:~$ sudo cat /etc/vsftpd.conf | grep -v "^#"

At this point, the configuration file would look more or less like this.

Now you have to open the necessary ports for vsftpd to work.

:~$ sudo firewall-cmd --add-port=21/tcp --permanent
Success
:~$ sudo firewall-cmd --add-port=30000-30100/tcp --permanent
Success
:~$ sudo firewall-cmd --reload
Success

Now let’s create the test user service.

:~$ sudo useradd -d /home/user1 -m -s /bin/bash user1
:~$ sudo passwd

Finally, you start the service and check its status.

:~$ sudo systemctl start vsftpd
:~$ sudo systemctl status vsftpd
● vsftpd.service - Vsftpd ftp daemon
   Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; disabled; vendor preset: disabled)
   Active: active (running) since Wed 2019-06-05 10:44:50 -04; 32min ago
 Main PID: 2888 (vsftpd)
    Tasks: 1 (limit: 4915)
   CGroup: /system.slice/vsftpd.service
           └─2888 /usr/sbin/vsftpd /etc/vsftpd.conf

The anonymous user is enabled by default. Its folder is /srv/ftp/ you can create alli files for download. You can even access it from your web browser. ftp://your-server/

Now, it’s time to install an FTP client. In this case I will use Filezilla.

Using Filezilla as the FTP client on OpenSUSE

First you have to install it.

:~$ sudo zypper in filezilla

Then you have to create the connection. To do this, go to the File menu and click on the Site Manager option. In the window that appears, configure your connection. I’ve done it this way.

And this is it. Now you can start enjoying the FTP server. Note that I’ve already uploaded a test file.

Enjoy it.
