Free secure ftp overview 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.

Secure Back Door (SBD) is a tool that provides ultra-secure and minimal access to a computer, which allows you to run a single command based on a one time key. It is good if you dont want to have an SSH server running all the time, and only want to start it when needed. Because it has only a few lines of code, it is hoped that it will be less susceptible to security exploits than a program like SSH.
The protocol is detailed to an extent in the text file PROTOCOL, I will update it with more details as I have time, but the most important details are included already.
If you are a crypt analysis, or just like a challenge, I appreciate anyone who is willing to look through the protocol and/or code and point out possible security implications and flaws in design!
Enhancements:
- Fixed a few minor compiler warnings
- Updated license year to 2005
- Uncommented execution code in sbdd, so now sbdd will execute incoming commands
- Updated README documentation for compilation

Cheyenne Secure Web Server (SWS) is a comprehensive enterprise solution for Apache server. Cheyenne Secure Web Server combines http firewall, JAVA, PHP, PERL and a domain control system with Apache HTTPD platform.

Secure Login provides a login extension similar to Operas Wand login.

It uses the built-in password manager, but deactivates the prefilling of login forms.
Instead, you are now able to login with one click or a keyboard shortcut (ALT+N).
Just add the Secure Login toolbar button to your toolbar, or use the provided statusbar icon.
If you hover over one of the icons, a tooltip is shown, displaying the login url and the number of available logins (users).
For more than one user or login forms on the current page a selection prompt is displayed on login.
You have the option to play sound notifications (*.wav) for found login data on the current page or when logging in.
All the options can be changed using the Secure Login settings menu or the statusbar icon context menu.

Secure Login provides you with a number of Security enhancements and helps protecting you from phishing:

Disabling the prefilling of login forms prevents malicious JavaScript code to automatically steal your login data.
This is due to the fact that no login data is inserted in form fields before the user clicks on the login button or logs in using the keyboard shortcut.
To make sure you login to the right website, the second level domain of the login url is compared to the second level domain of the current page.
If they do not match a dialog prompt is displayed before login.

SecureLogin provides you with an optional setting to protect you from all JavaScript code during login.
This can prevent cross-site scripting (XSS) attacks without having to deactivate JavaScript completely.
If you enable this option, your login data will never be inserted in any form fields nor will the login form be submitted.
Instead your credentials will be sent to the login page using internal Firefox methods.
Not all login forms will work this way, e.g. not those using JavaScript routines.
Therefore, you can add such websites to an exception list.

CrossFTP for Firefox is a versatile Cross-Platform FTP client extension.

This plugin contains two FTP tools: CrossFTP Client and Server. which will appear in the Firefoxs Tools menu:

- CrossFTP Client is a versatile GUI FTP client for multiple platforms. It uses a familiar, Explorer-like interface that even the most novice user can master in minutes.
- CrossFTP Server is a professional FTP Server for multiple platforms. It offers you a high-performance, extremely configurable, and most of all a secure FTP server.

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

Net::FTPServer is a secure, extensible and configurable Perl FTP server.
SYNOPSIS
ftpd [--help] [-d] [-v] [-p port] [-s] [-S] [-V] [-C conf_file]
[-P pidfile] [-o option=value]
Net::FTPServer is a secure, extensible and configurable FTP server written in Perl.
Current features:
- Authenticated FTP access.
- Anonymous FTP access.
- Complete implementation of current RFCs.
- ASCII or binary type file transfers.
- Active or passive mode file transfers.
- Run standalone or from inetd(8).
- Security features: chroot, resource limits, tainting, protection against buffer overflows.
- IP-based and/or IP-less virtual hosts.
- Complete access control system.
- Anonymous read-only FTP personality.
- Virtual filesystem allows files to be served from a database.
- Directory aliases and CDPATH support.
- Extensible command set.
- Generate archives on the fly.
Installation:
A standard ftpd.conf file is supplied with the distribution. Full documentation for all the possible options which you may use in this file is contained in this manual page. See the section CONFIGURATION below.
After doing make install, the standard ftpd.conf file should have been installed in /etc/ftpd.conf. You will probably need to edit this file to suit your local configuration.
Also after doing make install, several start-up scripts will have been installed in /usr/sbin/*ftpd.pl. (On Debian in /usr/bin or /usr/local/bin). Each start-up script starts the server in a different configuration: either as a full FTP server, or as an anonymous-only read-only FTP server, etc.
The commonly used scripts are:
- /usr/sbin/ftpd.pl
- /usr/sbin/ro-ftpd.pl
The first script is for the full FTP server.
These scripts assume that the perl interpreter can be found on the current $PATH. In the rare situation when this is not the case, you may need to edit these scripts.
