Dou,
There are a lot of libraries for Ruby that you can use along with
the Watir libraries for other pieces of your testing. If you're
looking for telnet for example you might want to take a look at Ruby's
builtin net/telnet documentation:
http://www.ruby-doc.org/stdlib/libdoc/net/telnet/rdoc/in
That's one of the advantages of using a real programming language like
Ruby. You can go along using Watir, but when it's time to telnet, you can
use Ruby's 'net/telnet' library, too:
http://www.ruby-doc.org/stdlib/libdoc/net/telnet/rdoc/index.html
Likewise database connections, SOAP clients, etc
I don't know whether it's suitable to ask this question here.
Watir is good tool for web testing, but during testing, usually there are a
lot more things to do other than operating the web browser. It may be telnet to
another machine to execute some commands, or just exec some command on the
