Blocked network access for dizmoLive

There are situations where an application or service running on the same computer as dizmo might be blocking the network connection to properly use dizmoLive by locking access to the network in an exclusive way. This pages explains how to find the software that is responsible for the problem in order to stop it and make dizmoLive working as expected.

Windows

Open a «Cmd» window by holding down the Shift key and right-click any folder on the desktop. Select the context menu entry, «Open command window here». Now type (or copy-paste) the following command:

netstat -ano | findstr /r 1900

This will usually display something like this

UDP   192.168.0.55:1900                  *:*      1234
UDP   127.0.0.1:1900                     *:*      1234
UDP   [::1]:1900                         *:*      1234
UDP   [fe80::fc29:1234:5678:9abc%4]:1900 *:*      1234

type the following command using the process number found at the end of each line above instead of <pid> (in the example above this is 1234). Repeat this for each process number you get.

tasklist /FI "PID eq <pid>" /FO TABLE

This will display something like

Image Name         PID Session Name     Session #    Mem Usage
============= ======== ============== ===========  ===========
svchost.exe       1234 Services                 0      5,532 K

The answer above means that Windows is using the same network resource like dizmo which is ok as the operating system uses it in a shared way. If however you get the name of a different application try to find it and close it. This should close the blocking application and let you use dizmoLive now.

If you cannot find the application, try the following command in the command window replacing <pid> with the number shown in the PID column (1234 in the example above)

taskkill /pid <pid> /f

Mac OS X

Open the «Terminal» application that usually can be found in the «Utilities» folder inside «Applications». Now type (or copy-paste) the following command:

sudo lsof -i | grep -i ssdp

This will first ask you to type your local Mac user password and then display a line that might look like this

HDHomeRun 1234 user 19u IPv4 0x20e0b26be69749d7 0t0 UDP *:ssdp

indicating that the application named HDHomeRun is using the same network resource as dizmo and is probably blocking it. Try to locate the application and close it. Then try starting dizmo again. If you cannot find the application given, try the following command in Terminal replacing <pid> with the number shown next to the application name (1234 in the example above)

sudo kill <pid>

This should close the blocking application and let you use dizmoLive now.

Linux

Open a «Terminal» window and type (or copy-paste) the following command:

sudo lsof -i | grep -i ssdp

This will first ask you to type your user password and then display a line that might look like this

PlexMed 1234 user 19u IPv4 0x20e0b26be69749d7 0t0 UDP *:ssdp

indicating that the application named PlexMed… is using the same network port as dizmo and is probably blocking it. Try to locate the application or service and close it. Then try starting dizmo again. If you cannot find the application given, try the following command in Terminal replacing <pid> with the number shown next to the application name (1234 in the example above)

sudo kill <pid>

This should close the blocking application or service and let you use dizmoLive now.
