just a suggestion, putty does not require an “install” if you can download it to the system you should be able to run it, otherwise put putty on a usb device and use it that way, I assume you are using windows systems as linux has ssh from cli, I would guess MAC OS does too. Thats my 2 cents till a web cli is devised. also ensure on your windos systems you have the “runas” feature enabled to bypass the user level limitations.
