[Dev] web app design question

[M. Mueller/bhu5nji]

I've got a Linux based router  that I want Tier 1 technicians to configure 
and operate (start and stop) using a browser interface.

The router uses text files (.conf) to read its configuration.

The start and stop functions are scripts requiring root priviledges.

I'd like the browser-to-router interface to be secure.

Tier 2 techs use SSH to get at the full system.

Any recommendations on how to implement these requirements?

TIA,
Mike
