For example, if you type a host name wrong, or just make up a host name. When you try to connect to a legitimate host that is offline (i.e. its name exists, but the host is not on the network at the time), you get the "timed out" message. The difference is significant and important when you are trying to figure out what went wrong. Fafa's use of the word "offline" to describe a host that doesn't exist at all was not accurate. It is also not generally productive to be rude when asking VOLUNTEERS to help you. The likely response is "fix it yourself", which is my suggestion for this case. - Bob
