There are syntactical and "tactical" mistakes. First, you cannot write
[-
# code
[+ $output+]
# code
-]
second, variables are written $name not $ name or name,
you should
[-
# code
print OUT $output;
# code
-]
an at last, usually embperl caches entire page before outputting. You must
force it to give results as they appear. And anyway it depends on browsers
decisions how to render the page.

No guarantee of what the PATH variable is for the web server, I would
spell out the full path to ping.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
