FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on an Ubuntu 11.04 server.

This tutorial explains how you can integrate ClamAV into ProFTPd for virus scanning on a Debian Lenny system. This is achieved through mod_clamav. In the end, whenever a file gets uploaded through ProFTPd, ClamAV will check the file and delete it if it is malware.

This tutorial explains how you can integrate ClamAV into PureFTPd for virus scanning on a Debian Lenny system. In the end, whenever a file gets uploaded through PureFTPd, ClamAV will check the file and delete it if it is malware.

If you create user accounts on a server, and then allow people to log on to the ftp server under those accounts, there’s a chance that some hacker could find a way out of the chroot jail. That would allow him to access areas of the file system where he has no authorization, and possibly to plant Trojans or other malicious programs.

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

FTP communication is not secure, all communication is plain text and can be easily captured. Despite this serious weakness, few do anything to secure it. There are simple ways to correct this with VSFTPD.

SSL/TLS With FTP

FTP is a file transfer protocol for exchanging files over any TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access). There are many existing FTP client and server programs. FTP servers can be set up anywhere between game servers, voice servers, internet hosts, and other physical servers.

Nautilus, the official file manager for the GNOME desktop, can help you perform tasks from browsing the filesystem to accessing Samba shares on your local network or FTP sites on the Internet -- and more. Here are a couple of tips and tools that will allow you to open a terminal window from Nautilus and resize and rotate images without opening any other program.
