Free ftp server software for linux

vsftpd 2.1.2 is an efficient GPL licensed FTP server for UNIX systems, including Linux. vsftpd is an FTP server, or daemon. The "vs" stands for Very Secure. Obviously this is not a guarantee, but a reflection that I have written the entire code base with security in mind, and carefully designed the program to be resilient to attack.

The only reason you might prefer a different FTP server to vsftpd is if you really need the configurability of one of the more bloated FTP servers. Having said this, note that vsftpd caters for the vast majority of use cases.

Even if vsftpd appears to be missing a feature, it is often satisfied by an external component such as PAM or xinetd / tcp_wrappers. In this regard, vsftpd is being a small modular component in the proper spirit of UNIX. Finally, consider moving to vsftpd even if it means sacrificing some whacky feature of your current FTP server. The security, performance and stability gains are waiting for you.

Chestnut FTP Search is a web application to search for files on FTP servers. Files can by searched only by file/directory names, nor be file contents. Users can query files by part of the file name, the entire file name, a regular expression, or a shell pattern.
The program is written in Python using web.py framework. To store file indexes PostgreSQL or MySQL is use.
Main features:
- Four search modes: partial match, exact match, regular expression, shell pattern. Every mode can by case sensitive or case insensitive
- Character set can by specified for particular server to allow non ASCII file names.
- Multi-threaded indexer
- i18n support

bftpd program is a small, easy-to-configure FTP server. It strives to be fast, secure and quick to install/configure.
Main features:
- Easy configuration
- Speed
- Support for most RFC FTP commands
- tar.gz on-the-fly compression/archiving
- Security with chroot without special setup
- No need for files (sh, ls...) in a chroot environment
- Logging to wtmp and to a logfile or syslog
- PAM and passwd/shadow support
- Support for SITE CHOWN/CHMOD
Running the server:
bftpd runs in either standalone or inetd mode.
If you want inetd mode
Add the following to your /etc/inetd.conf:
ftp stream tcp nowait root /usr/sbin/bftpd bftpd
Give inetd a HUP or reboot your system. Your FTP server should work now.
If you want inetd mode with xinetd
Add the following to your /etc/xinetd.conf:
service ftp
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/sbin/bftpd
log_on_success += DURATION USERID
log_on_failure += USERID
nice = 10
}

wzdftpd is a modular and portable FTP server, which supports SSL, IPv6, multithreading, and external scripts. It uses Unix-like permissions and ACLs, with virtual users and groups.
wzdftpd project also supports bandwith limitation (per user, per group, or globally), group administrators, and per command authorization.
Main features:
- Simple configuration file, supporting inclusions
- Online administration, using SITE commands
- Backends to store users/groups in different structures
- Modules: internal, using shared librairies, or external (scripts/applications), and protocols
- Extensions scripts can be written in TCL or Perl
- Powerfull event system
- Jobs scheduler, also known as crontab
- Users are virtual: you do not need to create users in system
- SSL/TLS support
- IPv6 support (Experimental)
- Server is designed to run as a non-privileged user to enforce security
- Server can detect ip changes (dynamic ips) and set ip and passive ip accordingly
- Cross devices operations (copy/move) (though can be slow)
- Logging support (compatible with the wu-ftpd standard)
- Designed for high performances: coded with C, multithreaded
- Portable: runs on linux, BSD and windows
Moreover, wzdftpd is based on a particular philosophy:
- free software: wzdftpd is, and will remain free software, meaning you have complete access to the source code, the right to modify it, and the right to redistribute it.
- transparency: source code is documented, and available to everyone. The bug-tracker database is also freely accessible, and any bug report will be considered appropriately.
- designed for users: any idea/suggestion is welcome, and even if all will not be implemented, they will be taken into consideration.
- respect of licenses: all libraries or code fragments used by wzdftpd are used in proper respect to the authors license. Any file/feature/library in contradiction with this idea will be removed immediatly.
Enhancements:
New features
- SQLite backend has been added
- Brand new Windows installer
- Extra SITE HELP documentation added for various commands
- SQL backends can connect to SQL servers using TLS encryption
Bugfixes
- Lots of spelling errors and ambiguities have been corrected in server responses
- Event triggers now work correctly on Windows when specifying full paths for the scripts
- First entry in a directory list is now correctly sent to the client
- MLST/MLSD command was missing the PERM= field
- Can now set the passive port range to just one port without the server crashing
- syslog output now works correctly
- Users can no longer CWD into a directory they dont have list/read permissions for
- Cookies code is now thread-safe, fixing some stability issues
- Dozens of other bugfixes and stability improvements
- Server will no longer randomly crash when using the "site shutdown" command

Secure FTP is a client application that allows for a 128-bit encrypted secure connection to be made to a server that supports FTP over SSL (or FTPS).
The application can be run via its graphical user interface (GUI) or from the command-line interface (CLI), allowing for headless (scriptable) operation. This makes Secure FTP a great option for both novice and advanced users.
The client is fully RFC 2228 compliant and offers both types of SSL connection options: explicit and implicit, which means more server compatibility.
Secure FTP is free to use for noncommercial use. Those wishing to use the client for commercial purposes are granted a license free of charge for 30 days.
The client is supported on Windows, Mac OS X, and any Unix platform where a Java 2 runtime environment (version 1.4+) is present. It was written in 100% pure Java.
Enhancements:
- The software was translated into French.
- Minor bug fixes and library updates were done.

pro-search is a crawler for FTP servers, SMB shares, HTTP servers, and DC++ networks.

Ftpmap enables you to find what software/version a FTP server is running according to its fingerprint.
Ftpmap scans remote FTP servers to identify what software and what versions they are running.
It uses program-specific fingerprints to discover the name of the software even when banners have been changed or removed, or when some features have been disabled.
IPv6 is fully supported.
Install>/b>
./configure
make
make install
Usage
Usage : ftpmap [-h] [-P ] [-u ] [-p ] -s
-h : help
-P : connect to port (default=21)
-u : login to the server as (default=ftp)
-p : use this password (default=mickey@disneyland.com)
-s : connect to FTP server running on (IP or name)
Whats New in This Release:
- Check for ESTP/ESTA.
- Dont give up when a command times out.
- More fingerprints.
