The glibc documentation blows for this, but what getdomainname comes from uname(2), not from any DNS-related configuration. Debian only ever sets this if you're using NIS. There's no real great way to get the current hostname; a lot of applications do a reverse DNS lookup on the primary network interface, with appropriate handwaving to define primary. Easiest might be to punt to hostname --fqdn, or an equivalent to its algorithm - which appears to be fetch the hostname from uname, do a DNS lookup on that, and a reverse DNS lookup on the result. -- Daniel Jacobowitz CodeSourcery, LLC - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
