Once it is installed you can test it by logging into your machine using the loopback..
I also tested it by finding out what my IP address is on my router, some routers have a little web server in them and so all you have to do is access that little web server, in the DSL routers that QWEST distributes, it is 192.168.0.1 , in some routers it may be 192.168.100.1 . In any case, once you find your IP address for your computer, go to another machine on your network and try it out, for example..
There is a webserver on the net, that if you do a search on google for "whatsmyip" will permit you to obtain your IP address for your machine. If you are on a DSL connection or a internet service provider that gives you a different IP each time, this IP won't be dependable, but if you are creative, you can use my last lesson on scp to copy your local machines current ip address to a web server, then ssh to it by reading that file. There are other ways, but I'll leave that up to you.
