Filezilla Ubuntu

Filezilla is an open-source and free, cross-platform application of FTP, consisting of Filezilla server and Filezilla client. Clients are present for macOS, Linux, and Windows, Servers are present only for Windows. Both client and server support FTPS and FTP, while the client could in inclusion connect to the servers of SFTP.

The source code of Filezilla is hosted over SourceForge and this project was provided in November 2003 as the Project of the Month.

History of Filezilla

Filezilla was begun as a class project of computer science in January 2001 second week by Tim Kosse and the other two classmates. Before they began to specify the code, they explained under which license they must publish it. They decided for making Filezilla the open-source project due to several clients of FTP were already present and they did not think that they will sell one copy if they enabled Filezilla commercial.

Features of Filezilla

There are a few advantages of using the Filezilla client:

• Send files with the help of an encrypted FTP and FTP like FTPS (client and server) and SFTP
• Supports IPv6 (the latest internet protocol version)
• Supports resume which specifies that the file transfer process could be continued and paused
• The ability for overwriting existing files just if the source file is new
• The ability for overwriting existing files only when the size of a file doesn't match
• The ability for preserving transferred file's timestamps provided supported by target server (uploading) or local system (downloading)
• Tabbed user interface for the process of multitasking, to permit browsing multiple servers or even send files between more than one server simultaneously
• Site manager for managing transfer queue and server lists to order the tasks of the file transfer
• Bookmarks for convenient access to almost all frequent uses
• Directory comparison to compare server files and local files within a similar directory. It will highlight the file in color when the file does not have similar information (size does not match or name does not match).
• Drag and drop option for downloading and uploading process
• Configurable limits of transfer speed for limiting the file transfer speed which supports decreasing transferring error
• Many filename filters, users are able to filter only particular files that include some conditions they wish
• Network configuration wizard supports configuring confusing settings of the network in the step-by-step wizard
• Keep alive, when the connection has been best for a long time it would inspect by transferring the command, i.e., keep alive.
• Remote file editing, for faster edit file over server-side. No need to edit, download in the system, and re-upload to the server.
• Supports 1.1/HTTP, FTP-Proxy, and SOCKS5
• Logging functions to files to debug saved on the custom location.
• The ability for exporting queues (finished, failed, pending) into a format file, i.e., XML
• Synchronized browsing of directories
• Remote file search for remotely searching files over the server
• Cross-platform. Execute on macOS X, *BSD, Linux, and Windows.
• Supports transfer and resume of large files (bigger than 4GB)
• Protect password storage secured with a master password
• Present in 47 languages around the world (Vietnamese, Ukrainian, Turkish, Thai, Spanish, Slovenian, Slovak, Serbian, Russian Romanian, Polish, Persian, Occitan, Nepali, Norwegian, Macedonia, Latvian, Lithuanian, Kyrgyz, Kurdish, Korean, Khmer, Georgian, Japanese, Italian, Icelandic, Indonesian, Hungarian, Hebrew, Galician, French, Finnish, Estonian, Greek, German, Dutch, Danish, Czech, Croatian, Corsican, Chinese, Catalan, Bulgarian, Basque, Armenian, Arabic)

There are a few advantages of using the Filezilla server:

• IP filters
• Permissions system with groups and users
• Remote administration
• Supports large files (bigger than 4GB)
• Speed limits
• Supports IPv6
• FTP and FTP over FTPS (TLS)

Reception

Chris Foresman negotiated with the clients of FTP for Ars Technica in May 2008, specifying of Filezilla, "Some friends in the tech support world often recommend the free and open-source Filezilla, which offers a Mac OS X version in addition to Windows and Linux. But I've never been thrilled about its busy interface, which can be daunting for novice users".

In August 2008 specifying for Ars Technica Emil Protalinski specified, "this week's free, third-party application recommendation is Filezilla... This FTP client is very quick and is regularly updated. It may not have a beautiful GUI, but it certainly is fast and has never let me down". National Capital FreeNet and the Go Daddy Clarion University of Pennsylvania suggest Filezilla upload files on their web hosting services.

Filezilla application is available inside the repositories of several distributions of Linux including Ubuntu, Debian, Linux-libre/Parabola GNU, and Trisquel. CNET provided Filezilla their largest "spectacular" rating- five stars out of five stars in January 2022.

Since the participation of the project in the program of SourceForge for creating revenue via adware, many reviewers began warning of downloading Filezilla and confused users from utilizing it.

Criticism of Filezilla

Bundled adware problems

In 2013 the hosting site of the project, i.e., SourceForge.net, gave the primary Filezilla download along with a download wrapper, providing extra software for all users to install. Several users reported that a few of the adware downloaded without permission, despite declining every install request or applying deception for obtaining the acceptance of the user to install.

Many reported effects are: search engines and start page being changed forcibly, web browsers being hijacked, popup windows, restart events and sudden shutdown, or privacy issues leading to lost the latest work. A few of the adware was reported for resisting restoration or removal of old settings or were said for reinstalling after apparent removal. Users also proclaimed adware programs for downloading and installing more undesired software, a few causing alerts for being malware from security suites.

The webpage of Filezilla provides additional options of download without installs of adware, but the connection to the adware download occurs as the main link, marked and highlighted as "recommended".

Filezilla shows ads (known as sponsored updates) if activating the application as of 2016. These ads occur as a part of the dialog, i.e., "Check for updates". A future controversy of Filezilla's use of an installer of bundled adware caused concern in 2018.

Plain text password storage

Filezilla stored every saved password and username as plain text until the 3.26 version, permitting any malware that had captured even restricted access to the system of the user for reading the data. The author of Filezilla, i.e., Tim Kosse was hesitant for adding encrypted storage. He specified that it provides a false security sense because well-crafted malware could contain a keylogger that will read a master password used for securing the data.

All users have debated that reading a master password for decrypting the encrypted storage is harder as compared to only reading unencrypted storage. A fork which is known as Filezilla secure was begun in 2016 November for adding encrypted storage. Also, encrypted storage was included in the primary version, which is 10 years after it's first requested in May 2017. Kosse managed that the feature didn't increase security as far as the operating system isn't secure.

Server of Filezilla

Filezilla server is a Filezilla client's sister product. It's a server of FTP supported by a similar project and offers support for FTP and FTP on TLS/SSL. Currently, the Filezilla server is available on the Windows platform only. Filezilla server is an open-source and free FTP server. The source code of Filezilla is hosted over SourceForge.net.

Advantages of Filezilla Server

Filezilla server provides its support for FTPS (FTP on TLS/SSL) and FTP. Some other advantages include:

• Speed limits
• GUI configuration tool
• Per-user permissions over an underlying file system
• Encryption with TLS/SSL for FTPS
• Compression with MODE Z (DEFLATE)

Issues of Filezilla Client

Filezilla Client doesn't operate a workaround for any error within the IIS server which leads to file corruption if resuming bigger file downloads, unlike a few other clients of FTP

Support of operating system

Connect to the Remote FTP Server with Filezilla

It is not difficult to connect to any remote FTP server with Filezilla. All we require is to launch the application of Filezilla. Then, we need to give IP address or hostname, password, username, and a port number to which the server of FTP is listening. After that, we need to press Quickconnect.

Now, a dialog box may pop up alerting us that our FTP connection isn't secure or the certificate of the server isn't recognized. If we are fine with it, then we need to press Ok to continue. We will be connected to our FTP server and can transfer files from and to the server respectively if everything is ok.

Installing Filezilla in Ubuntu 20.04
