Pure-FTPd
Pure-FTPd

Pure-FTPd free (BSD) is a secure, high-quality, and standard FTP server. It does not provide useless ringtones and whistles, but focuses on efficiency and ease of use. Simple answers to general needs also offer useful features that are unique to personal users and hosting providers.

Safety First

Pure-FTP gets continuous support and is always designed with consideration of security and efficiency. The server can work by allocating privileges for paranoid security. The chroot () emulation and default virtual accounts can run 100% rootless. Transferring passwords and clear text commands can be avoided: Pure-FTPd has optional support for the SSL / TLS encryption layer that uses the OpenSSL library.

Pure-FTPd is running on your server

The same source code is compiled and run on Linux, MacOS, OpenBSD, NetBSD, DragonflyBSD, FreeBSD, Solaris and its variants, Tru64, Irix, HPUX and AIX. Preinstalled dual packages are available for nearly all supported operating systems.

Pure-FTPd speaks your language

All message servers have been translated into English, German, Romanian, French, Polish, Spanish, Danish, Dutch, Italian, Brazilian Portuguese, Slovak, Korean, Swedish, Norwegian, Russian, Traditional Chinese, Simplified Chinese, Czech, Turkish, Hungarian and Catalan. This helps your customers understand the diagnostics even if they are not native speakers of English. The message is in a standalone file and can easily be converted to a new language or customized. Transparent conversion of the client series to the implemented file system with UTF-8 support.

Good choice for beginners

Beginners can install the Pure-FTPd server in 5 minutes. This can be as simple as installing a package, writing pure-ftpd, and that's all. You already have a server running and the client can start connecting. You don't need to review long and complicated configuration files; this can cause safety and reliability effects of errors that may occur. Pure-FTPd uses a simple command-line switch to enable the features you need. You can limit the number of concurrent users, limit bandwidth, hide system files (chroots), load / download rates, and load new, medium-load to avoid starvation.

Private messages can be viewed during login (even changing wealth files) and when the user is in a new directory. In addition, you can set the maximum percentage to prevent your disk from filling, and new uploads will be canceled after this percentage has been reached.

The FXP protocol (server to server) is applied. This can be used by anyone or only authenticated users. Kiddies uses rough tools to find hidden directories. Pure-FTPd provides protection against this. Secure anonymous access by default. For example, users cannot access point files (.bash_history, .rhosts, ...) unless you explicitly enable them. To see who is doing it, the pure-ftpho command allows you to view the table with the current active session, how much bandwidth each user gets, what files they download or download, where they came from, and so on. Shows.

High flexibility for ISPs and hosting services

  • The system account may have FTP access immediately. Authentication with PAM modules is also supported. Accounts under UID (for example, account logs <500) can be denied.
  • All accounts can be easily selected by default. For easy application, "reliable" groups can be defined without chroots.
  • FTP accounts may be different from system accounts stored in a standalone database. Some accounts may share the same system ID. The default indexing database allows very fast search. It works successfully with more than 1.5 million accounts on the same server. System accounts can be copied to a virtual FTP account, so that users can have different passwords for shell access and FTP access.
  • LDAP authentication is also fully supported. Pure-FTPd has been successfully tested with
    OpenLDAP and iPlanet Directory Server. Use the standard posixAccounts class.
  • Secure default encryption mixes can also be used on any LDAP server, even if they are not supported for this interference.
  • User information can be centered in the MySQL database as if the transactions were made or there were no transactions. All inquiries are fully customizable and can be created with user names, remote customer addresses, local IP addresses and ports. In this way, complex hosting
  • Rules can be easily implemented, even if there are multiple virtual servers on the same host and multiple virtual space with multiple users.
  • Various authentication methods can be chained in any order. For example, SQL accounts, LDAP directories, and fog The tem accounts can be used together with the maan.
  • Custom authentication methods can be added easily. Pure-FTPd supports external authentication modules and a new backend write can be as simple as a few shell arrays.
  • Pure-FTPd supports virtual quota systems: a ccount can have its own quota (maximum number of files, maximum total size) even when they use the same system.
  • Bandwidth restrictions are supported by different settings for uploading and downloading.
  • Each user can be given an individual quota, ratio and bandwidth.
  • Each user can only be allowed to connect to a specific IP address range or only to his or her virtual host.
  • Each user can be limited or restricted separately to the main directory.
  • Each user can only be allowed to connect during the configured time period (eg during business hours only).
  • Anti-ware systems prevent users from processing when they find a directory that can be written publicly. Files owned by anonymous ftp user cannot be downloaded (sysadmins must control them by changing ownership). In addition, FTP users cannot create directories to hide files.
  • Each external shell script can be called after the installation succeeds. Virus scanners and database archives can be easily edited.
  • Maximum concurrency connection can be applied from the same IP address to avoid bandwidth hunger and denial of service attacks.
  • Downloads may be canceled if the system load is too high.
  • The directory list lists the maximum number of files that can be specified. The recursive list is fully supported by the maximum parameter depth. Thus, you can search your users recursively without a simple denial of service.
  • Pure-FTP instructs and provides real-time reports to anyone who does activities on the FTP server, including bandwidth usage. The result can be a complete web page, and it can work as a standard CGI program that is compatible with any web server. XML and text reports are also available and shell script formats are concise and easy to parse.
  • Log files are correct and use standard syslog properties. Additional Apache-like log files (CLF) can be generated. Compatible with all web statistics software. An extended format called statistics is also implemented and works with sophisticated third-party statistics software such as FTPStats and ModLogans. FTP Stats provides detailed user statistics.
  • Home directories can be prepared on request. This is very useful on LDAP and SQL backends: just enter the line in the database and the account is ready to use. There is no need to create any indexes for this user: it is created automatically when it first enters.
  • Some virtual FTP servers can be hosted on the same computer with standalone trusted IP for administration.
  • Access to point files can be restricted so that users can access .ssh directories, .bash_history files, .rhosts files, and so on. Can't read / write.
  • Safe use applies to the user's home directory. Customers cannot disable their account with the "chmod 0 /" command in an unsafe way. The "chmod" command can also be disabled completely.
  • Some Pure FTPd servers with different settings can run on the same host without conflict.
  • Users can monitor symbolic links while chrooting, even when they are out of chroot jail. This unique feature makes the shared content manageable.
  • Index aliases can be enabled to provide shortcuts to public directories.
  • Really load atoms. The web server does not show damaged partial images or PHP scripts when uploading files even when content is updated.

Compatibility with existing specifications, customers and servers

Pure-FTPd has one of the most complete FTP protocol specification applications. It includes the basics of protocol and also modern extensions like MLST / MLSD (list of expandable and safe for mirrors). RFC compatibility is very good, but there are many train customers in real life. Therefore, Pure-FTPd has a solution for many popular Windows client versions that violate the FTP protocol. Pure-FTPd also works with damaged artificial clients that do not stop the path correctly.

So if your settings are currently running with another FTP server, you can safely switch to Saf-FTPd without breaking anything or accepting customer complaints: everything works as it is for them, and the transition is transparent. IPv6 is fully supported. The EPSV protocol extension / EPRT is applied to IPv6 and each configuration option and the logging feature is IPv4 and Works with IPv6. Pure-FTPd is the first to implement ESTA and ESTP. These two commands provide guaranteed FTP data connections to improve protocol-level security.

The firewall is easy: Pure-FTPd can limit the port range for passive connections, force the IPs that are described to hide gateways, or disable passive connections to deal with damaged port forwarders.
