Network service discovery disabled: What does this mean for me?

1

It looks like avahi-daemon is started when the network connection is established (/etc/network/if-up.d/avahi-daemon). This notification is informing you that mDNS (Avahi) has been disabled. It's only used for a small number of applications that only work on the local network, it won't adversely affect your internet connection or DNS.

The most well known use for mDNS is sharing music with Rhythmbox (or iTunes) over your LAN. It's an Apple technology, but it's largely been ignored in favour of uPNP or DLNA.

To disable it, you must edit the file /etc/default/avahi-daemon as root:

sudo -i gedit /etc/default/avahi-daemon

and add this line (or change it if already exists to):

AVAHI_DAEMON_DETECT_LOCAL=0

MAKE A COPY OF THE FILE: avahi-daemon.conf before you continue for that just in case scenario!.

To stop your network from disconnecting, you just need to edit two files as "root", follow the next few steps.

Press Alt + F2 and enter the following command:

gksudo caja

File System > etc:

avahi:

avahi-daemon.conf:

and edit line 23 to this: (you just need to add ".a" in front of local so you get ".alocal")

Click on Save!.

Now go to: File System > etc > default > avahi-daemon and save a copy of the file, then on line 4, change the 1 to a 0 so it looks like this:

AVAHI_DAEMON_DETECT_LOCAL=0

Save and close all windows and restart and you should now have no connection fallout!.

I hope it helps!.

Thanks for the reply.
Ok. Here are my current settings and my followup question.

DNS Client - Started
Function Discovery Resource Publication - Not started
SSDP Discovery - Not started
UPnP Device Host - Not started

My question is: Inside the firewall settings, under "Allow a Program of Feature through the firewall" I have Network Discovery Enabled for Domain, Home, and Public. But it is still disabled under "Change Advanced Sharing Settings". Is Network Discovery enabled or not? Which setting takes precedence, the settings inside the firewall or the setting inside of "Change Advanced Sharing Settings?"

I will now proceed to enable these services that you have brought to my attention and see if I am able to "turn ON" Network Discover under Change Advanced Sharing Settings. I will repost afterwards. thanks...

We often get requests from people asking how to disable Network Discovery because they either don’t want to see any machines in the Network Resources list or they perceive a performance issue with the feature. I am writing the blog to discuss this feature and explain some of the potential options.

What is Network Discovery?

Network discovery is not a single thing. In general terms it is the process of gathering information about the Network resources near you. It consists of a group of protocols that all report to the Function Discovery platform. Probably the most well-known protocol is NetBIOS Browsing, but it also includes WSD, UPNP, SSDP, and even the registry. Typically you see this information in Network Resources/Network Neighborhood, but any application can potentially be programmed to use it.

I am looking at making a client/server application for Android (Client) and Server (Windows).

The purpose of the app is from the server (PC) it allows the user to scan the network for devices that are compatible with my C# application and then can send messages to and from the client and the server.

I've been reading the Android documentation and found the Network Discovery Service in android at http://developer.android.com/training/connect-devices-wirelessly/nsd.html.

My understanding of how this works is, the android application, sends a broadcast message with the service name, IP and port number that other devices can connect to it via. Therefore in my case the C# would receive this broadcast message and decide whether the service is something my C# application can support, and if so, then establish the socket connection to the android device with the details from the broadcast.

As I say I've found the android developer tutorial for registering the...

Hi there,

I am just wondering what these error messages in my console window means:

Alejandro,


Can you confirm that you are attempting restrict only the server from seeing the devices while simultaneously allowing those devices to have client network discovery settings?


Because, on the off chance that you aren’t, you could easily disable the network discovery settings on the devices themselves and therefore your server would not be able to see them. Again, typically speaking, network discovery settings are controlled by the devices themselves. If you were to disable network discovery on each of those devices, you shouldn’t be able to see them from your server.


If that is not an option, putting the Terminal Server in a different subnet or implementing one of the suggested alternatives such as Group Specific Server Isolation or IPsec Server Isolation is going to be your only viable option.


To quote the provided article for Group Specific Server Isolation, “Server isolation enforces a network...

When you want to transfer data to client machines connected in a network, you first have to establish a connection with them and then copy / move the files and folders. Unlike Windows XP, which often requires users to manually enter the source location (IP address) of system in a network to share data, Windows Vista and Windows 7 offers Network Discovery feature, which allows users to view all the client systems on the network. Windows lets you turn this feature on to easily share files with other computers on a network. When you want to restrict other from accessing your shared folders, you can simply turn Network Discovery off. By default, this feature is enabled, but can be easily disabled. In this post, we will guide you through the process of disabling Network Discovery feature in Windows 7.

First of all go to the control panel and choose the Large Icons option from the View By category.

Once done, choose the Network and sharing center option and then in...

Sorry to bump this post but I see it went unanswered, this issue still exists on Windows 7

If you turn off both the SSDP discovery service and Universal Plug and Play Device Host, all SSDP traffic is not stopped; User Datagram Protocol (UDP) port 1900 traffic may be logged in firewall logs or packet filtering device logs. If you run a trace of the traffic, the following information is displayed in the data section of the packet:

SSDP: Method = M-SEARCH SSDP: Uniform Resource Identifier = * SSDP: HTTP Protocol Version = HTTP/1.1 SSDP: Host = 239.255.255.250:1900 SSDP: Search Target = urn:schemas-upnp-org:device:InternetGatewayDevice:1 SSDP: Mandatory Extension = "ssdp:discover" SSDP: Maximum Wait = 3

Windows Messager sends SSDP packets, it doesn't use SSDP but creates the SSDP packets and sends them itself, (it's SSDP on it's own). You'd have to disable this in the registry.
