router configuration bug

[tofu]

When you configure the router with a domain name instead of an IP you get a strange error.

connection attempt to router failed: Success (0)

This in no way tells the administrator what is wrong. It would be best if we can get a better error for the misconfiguration.

It does the same for all components.

The option is called <ip/> for a reason. You need to give an IP address not domain name there.

You need a better error message. It is ridiculous that the current error says success. Don't make your users search because you are too lazy to let them know what is really wrong.

[smoku]

Sure.

I will gladly accept and integrate proper patch. :-)
