The extra entries in /etc/hosts are for both IP6 and IP4 the hostname entry with the trailing dot: myserver.example.com. denotes it as a fully qualified domain name, FQDN. If hostname shows the correct hostname with one domain, the problem is else ware. If it is else ware, I suspect your router is adding the example.com to every lookup. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
