Free ftp servers software for linux

Pure FTP Server is a fast, production quality, standards-conformant FTP server based on Troll-FTPd. Pure FTP Server has no known vulnerability, it is trivial to set up, and it is especially designed for modern kernels.
Features include PAM support, IPv6, chroot()ed home directories, virtual domains, built-in ls, FXP protocol, anti-warez system, bandwidth throttling, restricted ports for passive downloads, an LDAP backend, XML output, and more.
Beginners can install a Pure-FTPd server in 5 minutes. It can be as simple as installing the package, typing "pure-ftpd &" and... thats all. You already have a running server, and clients can start to connect.
Theres no need to review any long and complex configuration file, where possible mistakes could have security and reliability implications. Pure-FTPd uses simple command-line switches to enable the features you need.
You can limit the number of simultaneous users, limit their bandwidth to avoid starving your ADSL or cable-modem link, hide system files (chroot), have upload/download ratios, and moderate new uploads.
Custom messages can be displayed at login-time (even changing fortune files) and when an user enters a new directory. Also, to avoid your disks being filled up, you can defined a maximal percentage, and new uploads will be disallowed once this percentage is reached.
The FXP (server-to-server) protocol is implemented. It can be available for everyone, or only for authenticated users.
Kiddies are using common brute-forcing tools that are trying to discover hidden directories. Pure-FTPd provides a protection against this. Anonymous access is secure by default. For instance, users cant access dot-files (.bash_history, .rhosts, ...) unless you explicitely enable this.
And to watch whos doing what, the pure-ftpwho command shows a table with currently active sessions, how much bandwidth is taken by every user, what files they are uploading or downloading, where they are coming from, etc.
Enhancements:
- User names can now be up to 127 characters long.
- Compilation with PAM support has been fixed on Mac OS X, and the MySQL PASSWORD() function can now be used with MySQL >= 4.1.
- Logging now has the correct timezone.
- Support for charset conversions (RFC2640) has been implemented. Large files are now handled by default, using sendfile64() if possible. SITE UTIME and OPTS MLST have been implemented.
- MySQL queries can now include multiple statements and call MySQL 5 stored procedures.
- Transferring a lot of small files is now much faster than in previous versions.

ftpcluster provides a system which integrates several FTP servers into one.
ftpcluster integrates a number of individual FTP servers into a single large server. You can think of it as a network disk array with FTP as the access protocol.
Main features:
- FTP protocol
ftpcluster speaks enough FTP to upload, download, delete and rename files. You can also create, delete and rename directories.
- The cluster is working
Files can be distributed over your cluster nodes. ftpcluster knows how to handle files on your nodes.
- Replication
Files can be replicated to two or more node for fail-over situations.
- User authentication
Version 1.0.3: Users must authenticate against a local password file. Password are actually stored in cleartext.
- Filenames
Version 1.0.3: Filenames are not limited to a certain set of characters. Theres optional support for blanks and/or arbitrary characters in filenames. You can however restrict your users to usual UNIX filename conventions.
- Partial support for FTP REST command
Version 1.0.7: The cluster supports the REST command for downloads, for uploads only if the file is stored on the cluster.
- System checker
Since version 1.0.9 there are programs to check and repair cluster nodes.
Enhancements:
- Programs to check and repair the cluster were added.
- The FXP configuration documentation was started.

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

mjhservers is a project which consists of event-driven servers for FTP, POP3, LMTP, TACACS+, and others.
mjhservers is a set of highly configurable event-driven servers for FTP, POP3, LMTP, TACACS+, and other protocols. These servers feature a modular authentication sub-system, SSL, and IPv6 support, and are very scalable and efficient.
The software should compile out of the box for recent versions of Linux, FreeBSD, NetBSD, OpenBSD and Solaris.
Daemons provided by "mjhservers":
- spawnd is a broker with load-balancing functionality that listens for incoming connections on IP, UNIX or possibly IPv6 sockets, accepts them and finally forwards them (using ancillary messages over UNIX domain sockets) to the spawned server processes.
- ftpd is a highly configurable event-driven FTP daemon with TLS/SSL and IPv6 support, and much more.
- pop3d is an event-driven POP3 daemon. The manual has a short description on required Postfix patches, too (alas, these are quite out of date, and may or may not apply cleanly to current versions).
- lmtpd is an event-driven LMTP daemon, useful only in conjunction with pop3d.
- mavis and mavisd implement the modular authentication sub-system used by ftpd, pop3d et al.
- mod_auth_mavis is an Apache module for MAVIS based authentication.
- tac_plus is an event-driven TACACS+ daemon which utilizes the MAVIS backend for authentication and authorization (and may get its user data from LDAP, a suitable minimalistic tacacs.schema for OpenLDAP is included).
- tcprelay is an event-driven TCP connection forwarder.
- tcpmapd is an experimental daemon that interfaces the MAVIS system to Postfix.

proFXP provides a command-line fxp (server-to-server FTP) client.

proFXP is a command-line FXP (server-to-server FTP) client written in Perl. It features tab-completion of remote file/dir names, SOCKS4 firewall support, and a powerful interface right down to the FTP protocol layer.

proFXP is a FXP (server-to-server FTP) client written in Perl. It features TAB completion, site management, idle timers, SOCKS support, active and passive mode, different listing modes and a very powerful "down-to-the protocol metal" 2-char-command command line interface, pleasing newbies and hardcore hackers alike.

The binary below should work on libc6 Linux systems. The crash with multiple instances should be worked around now.

If you get the sources, youll need to get some perl modules off CPAN to make it work. If youre not root, or you dont know what CPAN is, you may get into trouble.
