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

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.

Server

There are several TFTP server implementations, some are listed below and iputils also includes a version of tftp.

Note: Make sure not to start different TFTP implementations at the same time. They will fail with an error got more than one socket, because only one may listen to the default TFTP port 69.

tftp-hpa

Install tftp-hpa and then start tftpd.service.

To modify service parameters edit /etc/conf.d/tftpd.

atftp

Install atftp and then start atftpd.service.

To modify service parameters edit /etc/conf.d/atftpd.

Client

Install tftp-hpa and then tftp your day away!

$ tftp
