I am installing the latest version of ubuntu server following the perfect setup instructions when i type hostname i get back dmproductionsinc.hsd1.comcast.net but when I type hostname -f Iget unknown host I'm pretty confused. I tried following the example, replacing with my info.what to do? I am using a d-link router could this be prob?
if you are doing that from inside the network than you will look at the first device that is connected the to public IP / WAN IP which is the router i say if you using one if you are inside the network and wantting to use the DNS name to look at mysql server than maybe set the DNS name to localhost IP or use localhost than DNS.name.here.com.au
