在Linux下安装完resin后，每次启动都出现如下错误：
[11:06:45.617] {watchdog-} WatchdogProcess[Watchdog[],7] starting Resin
Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: bogon: bogon
Jul 6, 2010 11:06:46 AM com.caucho.boot.WatchdogProcess runInstance
WARNING: WatchdogProcess[Watchdog[],7] watchdog socket timed out
原因是/etc/hosts文件里没有主机名为：bogon的，解决方法就是在hosts文件中加入bogon，修改后的hosts的文件是：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 bogon localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Local host name unknown: java.net.UnknownHostException:
