Is RFC 7440 implemented?

[jeffsilverm]

I am working for a large software company that shall remain nameless.

We are migrating from tftpd-hpa to Windows Deployment Server (WDS) because WDS supports RFC 7440 and I have found no open source TFTP server that does.

Bright ideas, anybody?

Many thanks

It would appear that centos 7.5 with tftp server 5.2.22 (or later or post Feb 2018) has the RFC7440 patch applied. https://rpmfind.net/linux/RPM/centos/7.7.1908/x86_64/Packages/tftp-server-5.2-22.el7.x86_64.html

My fog server that runs on centos 7 appears to have the required version of in.tfpd
