The Trivial File Transfer Protocol (TFTP) provides a minimalistic means for transferring files. It is generally used as a part of PXE booting or for updating configuration and firmware on devices which have limited memory such as routers and printers.

This article describes how to set up a tftpd server under Arch Linux using the tftp-hpa package.

Installation

Install the package tftp-hpa which can be found in the official repositories.

Configuration

Create a copy of the tftpd.service unit, and modify ExecStart with the appropriate directory to use as the tftp root.

# vim /etc/systemd/system/tftpd.service
[Unit]
Description=hpa's original TFTP daemon

[Service]
ExecStart=/usr/sbin/in.tftpd -s /srv/tftp/
StandardInput=socket
StandardOutput=inherit
StandardError=journal

Run

Start tftpd:

# systemctl start tftpd.socket tftpd.service

To start tftpd on boot:

# systemctl enable tftpd.socket

Troubleshooting

tftpd startup fails if ipv6 is disabled

If tftpd startup fails without leaving error messages, it might be because ipv6 is disabled and you are not explicitly telling tftpd not to use ipv6. You can make tftpd start by enabling ipv6 or by telling tftpd to only use ipv4, adding the '-4' switch to /etc/conf.d/tftpd

/etc/conf.d/tftpd
TFTPD_ARGS="-l -4 -s /srv/tftp/"
