TFTP client from the ESXi shell

I am automating the installation of a ESXi host with a scripted USB install. I need to fetch some information in a file stored on a router. Thios will be done in the kickstart script, ks.cfg, that is executed when the usb is booted. I see I can use scp and wget, but the guys controlling the router prefer me to use tftp if I can. There does not seem to be a tftp client available in the ESXi shell after install, so I was wondering if I could find a standalone tftp client, package it and include it with the ESXi USB install - or find some other solution for the tftp connection problem. Package a tftp client and include it with the ESXi USB install is not a problem, but I have a problem finding a standalone tftp client I can use.

Any suggestions?

There is no tftp client in ESXi, because VMware have created a lightweight hypervisor, with a small footprint.

You would need to compile a tft client for use with the ESXi kernel.

Thank you.

If you see this guide:
You see the guy includes ovf-tool with the ESXi installation media.

I was thinking of doing the same with tftp, if I could just find a standalone client that is good to use. I guess I will have to do by trial and error maybe.

or build your own, or find a tftp client application, which is supported for that version of the OS.

We do not do anything with the installer, which is bespoke, not supplied by VMware, to ensure it's vanilla and supported by VMware.
