Four Free TFTP Servers for Windows

by

A good TFTP server should be part of every admin’s toolkit. We’ve rounded up some of the best free TFTP server applications we could find and compared them all below. But first some basics:

What is TFTP?

TFTP, or Trivial File Transfer Protocol, is a very basic file transfer protocol. It’s simple, non-extensible, and usually used for transferring small files.  TFTP uses UDP, meaning it’s connectionless with no error checking, hence the term “trivial”. And, it’s best suited for transferring smaller files over a LAN, not a WAN or the Internet.

For a network administrator, TFTP is an essential way of backing up router and switch configuration files, or copying files for operating system upgrades. It could also be used to serve PXE boot files to thin-clients or network-based workstation installation systems.

There are a wide range of TFTP servers available, each with slightly different features. Some are very basic, others include more advanced features like security enhancements. Take a look at the picks we’ve rounded up below – you’re sure to find one that meets your needs!

Our Recommendation: SolarWinds Free TFTP Server (Free Download)

SolarWinds offers a range of free tools that complement their Orion suite of network management products, which we’ve recently reviewed. Their Free TFTP server has been very popular with admins thanks to its flexibility and ease-of-use.

The server can run as a Windows service and includes the ability to transfer large 4 GB files. It also runs as a multi-threaded program, allowing uploads from multiple network devices simultaneously.

On the security side of things, you can authorize specific IP addresses or ranges of IP addresses for transfers – helping to place some control around what is otherwise an unsecured service.

WhatsUp Gold TFTP Server

WhatsUp Gold makes a wide range of great network management software. (We reviewed WhatsUp Gold Premium here.)  Their Free TFTP Server is just as good as any of their paid products.

Their TFTP server supports large file transfers, up to 4 GB, and runs as a Windows service. It also has some great security features – including the ability to restrict client permissions to the server and restrict TFTP server availability by subnet.

It also allows the server to be bound to either a single IP address, or all available addresses on the server – giving you an extra level of control over what ports you’re exposing.

TFTPD32 from Philippe Jounin

TFTPD32 has become the go-to TFTP server for many admins ever since Cisco and 3Com stopped providing TFTP software years ago.

TFTPD32 is free open source, and includes a number of useful additional server features like Syslog, SNTP, DHCP, and DNS. And don’t let the name fool you – there’s a 64-bit version available for newer O/Ses too, called TFTPD64.

The TFTP server component is multithreaded to support multiple uploads at once, and has some security features, as well as interface filtering.
