You go to the web site with the applet and the applet loads and runs
on the JVM already installed on the machine and most likely displays
in the browser.
It's somewhat more complicated than this, but you can think of an applet
as a specially restricted type of Java program. Unlike a Java application,
applets have some substantial restriction on the types of things that they
can do -- they can only open certain kinds of windows, can only open net
connections according to certain rules, etc. The trade-off you get in
exchange for these restrictions is that an applet is allowed to run in
most Java-capable web browsers.

How does the Yale SSH applet get around the Java security model that
only allows connections back to the machine that the applet was served
from? Are they also doing port forwarding?

Where is a website that provides an applet for making a telnet connection
from a browser?

What use is that? It won't let you telnet to another host, even if you
login to mnet first.

Unfortuneately, I can't test it from here as "This applet also does not
function on Macintosh computers.". However I will make note of it for
the next time I seek to use a PC while traveling (after first trying
telnet://....).
Is there a version somewhere for Macs?

"Due to differences in Java security implementations on the Macintosh, the
Yale-signed web-based SSH applet will not work on a Macintosh."

That's what I love about Java. It really lives up to the promise of
"write once, run everywhere.."

Should be revised to "Write once, run most places maybe if you're lucky"?

Re #31: I think that's an excellent idea. (In the mean time, someone
who wanted to use it could *probably* just install it in their own
public_html directory, I imagine.)

I would agree to put it in my home dir, but I think we are not supposed
to upload java applets there.

Can't recall if there's a policy on applets. They run on the
user's browser and hence don't strain Grex's processing resources.
A concern with posting graphic images - which *is* against policy
- is that they tend to be large and therefore would excessively
tax Grex's limited network bandwidth as hundreds or thousands of
internet users download them, especially if they are inline images
on someone's web page and hence downloaded automatically as people
access the web page. Applets on the other hand tend to be an
order of magnitude smaller than images and are invoked only at the
user's request. So as long as there are no copyright issues with the
applet, I don't see that the same rationale applies as for images.
Do any other staffers recall if we have a policy on applets?

That was my point, expressed better than I expressed it.
There is a 1mb limit on disk usage that one shouldn't exceed.
