Hi,
I'm using Ruby 1.8. How do I get my server name? I'm running Apache
2 on Fedora Core 6 Linux. I tried "ENV["server_name"]", but got an
error.

Since ENV is a hash, why don't you open up irb and type
ENV.each { |key, value| puts "#{lkey} - #{value}" }
It's a bit quicker than expecting a reply on a mailing list.

You shouldn't get an error - it should give nil for unknown key.
If you're using erb templates, try something like
<%= ENV.inspect %>

It quacks like a hash, so it must be a hash 
Of course, it's not a real Hash instance, but you can work with it as
though it was a Hash.
ENV.each { |key, value| puts "#{lkey} - #{value}" }
There's a typo: not #{lkey}, byt #{key}

I was actually surprised to see that ENV.class returns Object. It
certainly acts like a Hash so...

Right. Sorry about that

Thanks all for your replies but there's something odd. I guess I'm
still confused about how to access values from this thing that is not
quite a hash. In irb, I did as Andrei suggested and thought I saw a
HOSTNAME key, but when I try and print out the value ("puts
ENV['HOSTNAME']"), I get nil. Why does it appear when I print out the
hash but not when I try and access the value individually?

How about
require "socket"
...
host_name = Socket::gethostname

Why did you think leaving out the:
puts ENV['HOSTNAME']
as the next statement would help prove your point?
