You're still making assumptions here that the host is using DNS, which is by no means the only way to configure host name resolution, and in fact almost all Unix systems use a combination of multiple methods simultaneously. The hostname need not match any A records. For my patch to work, all that matters is that the configured host resolution mechanism can turn the hostname into an IP, and that resolving that IP gets you a domain name. That's guaranteed to work, because if it doesn't your machine is broken. > Just imagine that there was no such thing as `hostname` in kernel. I'm not going to imagine that because it's a requirement of TCP/IP. All machines have a hostname. -- Derek D.
