I'm assuming you mean "Web Based SSH"... For truthiness:
en.wikipedia.org/wiki/Web-based_SSH
I always considered the approach "too risky" though -- as Scotty would say the more you overwork the plumbing the easier it is to stop up the drain; is it REALLY so hard for someone who has ANY business logging into BASH to install Putty or just use whatever flavor of terminal your *nix machine has built in?
