I'm struggling to get enableLookups to work on a new Ubuntu 8.10 tomcat 6.0.18 install. Calls to httpServletRequest.getHostName() always return the IP, instead of the host name. I set the access log to resolve hosts and it also shows the ip.
Tomcat 6.0.18 and the same webapp perform the reverse lookups fine on a WindowsXP machine. It doesn't appear to be a permissions problem, as I've temporarily granted AllPermission to my webapp. I've traced it down to java.net.InetAddress.getAddressFromNameService(String host, InetAddress reqAddr) and the subsequent call to sun.net.spi.nameservice.NameService.lookupAllHostAddr(host), which returns null. Inside getAddressFromNameService, the host is the valid host that I wish would be returned. Since the lookupAllHostAddr(host) call fails, getAddressFromNameService then throws an UnknownHostException. I also tried setting -Dsun.net.spi.nameservice.provider.1=dns,sun but that didn't make a difference. Could it be a dns config issue on my ubuntu box (hosted by slicehost)? Using the host command and an IP in question returns the host name that I want to get back from httpServletRequest.getRemoteHost(). Any tips for me? I'm a linux noob.
