I check my /etc/hosts and there are this lines:
127.0.0.1 localhost
192.168.1.2 DiskStation


I have tryed to reinstall serviio packet many times and with th java version 6 and 7 i have the same issue.
Please i need help...
Thaks

I have the exact same problem on alphaos, a arch linux derivative

I have no explanation for you other than a workaround

it seems serviio is expecting a hostname of format "number name"
Speculating here but serviio may expect "ip-number name"?????

so if I set hostname to something like "1 DiskStation" it works.

on linux you do from terminal

  Code:

hostname "1 DiskStation"

You may be able to change /etc/hostname file instead to "1 DiskStation"
if that file is present on your system

with this you avoid the part with

  Code:

java.lang.NullPointerException: replacement
at java.util.regex.Matcher.replaceFirst(Matcher.java:950)

after further digging I came across this thread

https://community.oracle.com/message/7079881

and maybe the developer of serviio could do some variation of this code

  Code:

   /**
    * Best attempt to get the local hostname, with or without the existence of a DNS entry.
    * @author mcarter@uk.ibm.com
    * @return Short version of the local hostname.
    * @throws UnknownHostException There is a problem with the DNS entry for this host and/or this JVM implementation
    * does not return the standard error string.
    */
   public static String getLocalHostName() throws UnknownHostException {
      try {
           return (InetAddress.getLocalHost()).getHostName();
      } catch ( UnknownHostException uhe ) {
          String host = uhe.getMessage(); // host = "hostname: hostname"
          if ( host!=null ) {
              int colon = host.indexOf(':');
              if ( colon>0 ) {
                 return host.substring(0, colon); // Dangerous, this is JVM dependant code.
              }
          }
          throw uhe;
      }
   }

perhaps use something like below in ProfilesDefinitionParser

  Code:

try
  {
       COMP_NAME = InetAddress.getLocalHost().getHostName();
    } catch (UnknownHostException e) {
       log.warn(String.format("Cannot get name of the local computer: %s", new Object[] { e.getMessage() }));
           String host = e.getMessage(); // host = "hostname: hostname"
           if ( host!=null ) {
              int colon = host.indexOf(':');
              if ( colon>0 ) {
                 COMP_NAME=host.substring(0, colon);   
              }
         }
     }


Found another fix that works for me

installed dnsmasq on my computer and configured it to act as a nameserver
now my hostname gets a valid nslookup and also serviio is happy

wich evidently makes me happy

I guess this issue is rare since many broadband routers act as local DNS servers. I've certainly never had it in the time I've run Serviio (spanning two different ISPs).
