AT-TFTP Server 2.0

AT‑TFTP Server is a lightweight, high‑performance implementation of the Trivial File Transfer Protocol (TFTP) designed for simple, automated file transfers on local networks. It’s commonly used for PXE network booting, device provisioning, and firmware updates for routers, switches, VoIP phones, and embedded systems. The server supports TFTP option negotiation (such as block size, timeout, and transfer size), concurrent transfers, and can run either as a standalone daemon or under inetd/xinetd. It also offers multicast TFTP for efficient PXE deployments, plus syslog logging and a configurable root/chroot directory for safer file serving.

Key features:

• Standards‑compliant TFTP with option negotiation (RFC 1350, 2347–2349)
• Multicast TFTP for scalable PXE boots
• Multi‑threaded, concurrent transfers
• Standalone or inetd/xinetd operation
• Syslog logging and configurable server root/chroot

Note: TFTP is unauthenticated and unencrypted. Deploy AT‑TFTP Server only on trusted networks, restrict it to specific interfaces, and use read‑only exports where possible. Runs on Unix/Linux; often packaged as atftpd/atftp.
