very strange. one last question about the hosts file. the network setup section of the install guide recommends separating the localhost name and actual hostname into two separate lines in the hosts file before starting the installation. did you do this before you started the install? if not, i wonder if that had something to do with things getting so mangled. anyway, if you fix it up, hopefully it'll all work fine. --Joe

I did not begin looking at this or editing it until I discovered this issue and there was not an external IP in the hosts file.
