I have my music on a small NAS, which includes a version of minidlna, and I listen over UPnP. My client will play albums, artists and playlists etc. I cannot upgrade either the server nor the client, nor use any other transport or protocol. I would like to be able to play a random selection of music each day, but neither the server nor the client have this feature. How can I best achieve this?

I have a IP camera on my network that is truly plug n play. As soon as I plugged the Ethernet cable in, it was accessible from 'the outside', without me having to touch my router's configuration. So I know my router supports UPnP. I can also NMAP it an see that the UPnP server is listening on 5431. I'm trying to enable a temporary FTP server (changed to port 29 in this case) that I want a friend to be able to access. I installed miniupnp and ran the following command. $ upnpc -l upnpc : miniupnpc library test client. (c) 2005-2013 Thomas Bernard Go to http://miniupnp.free.fr/ or http://miniupnp.tuxfamily.org/ for more information. No IGD UPnP Device found on the network ! miniupnp is apparently having trouble finding my router, or thinks it's not enabling UPnP. How can I troubleshoot this? EDIT: I just managed to get a telnet session into my IP camera. Coincidently it is also running miniupnp, I ran the binary and it returned: # ./upnpc-static -l upnpc : miniupnpc library test client. (c) 2006-2010 Thomas Bernard Go to http://miniupnp.free.fr/ or http://miniupnp.tuxfamily.org/ for more information. List of UPNP devices found on the network : desc: http://192.168.0.1:5431/dyndev/uuid:c03e0f29-4fec-ec4f-290f-3ec03e29ec0000 st: urn:schemas-upnp-org:device:InternetGatewayDevice:1 Found valid IGD : http://192.168.0.1:5431/uuid:c03e0f29-4fec-ec4f-290f-3ec03e29ec0002/WANPPPConnection:1 Local LAN ip address : 192.168.0.30 Connection Type : IP_Routed Status : Connected, uptime=127693s, LastConnectionError : Time started : Wed Feb 4 01:06:15 2015 MaxBitRateDown : 20819000 bps MaxBitRateUp 1209000 bps ExternalIPAddress = 90.220.126.102 0 TCP 80->192.168.0.30:80 'ipcam-h264' '' 1 UDP 41441->192.168.0.4:41441 'Skype UDP at 192.168.0.4:41441 (2956)' '' 2 TCP 41441->192.168.0.4:41441 'Skype TCP at 192.168.0.4:41441 (2956)' '' GetGenericPortMappingEntry() returned 713 (SpecifiedArrayIndexInvalid) So the same program on my IP camera is finding the IGD, wheras my laptop isn't.

I have been trying to harden my Debian system by stopping and disabling the 20 or so unnecessary services listening by default. One of them is called "minissdpd". Apparently this provides "discovery" services to plug-and-play devices, whatever that means. Seems kind of crazy to me that something intended to help local peripherals needs to be listening to Chinese hackers on the other side of the world. What does discovery services even mean? I looked in some vulnerability database, and sure enough minissdpd had a whole slew of vulnerabilities listed. How can they have this enabled in the default distribution? Seriously, its like install Debian, get hacked. Anyway, my main question is: now that I have disabled this service, is something bad going to happen (like plug something in and it won't work)?

I have a raspberry pi with a Wireguard Server and a number of peer's Android, Windows and another Raspberry pi. The tunnel works on all clients (for example i can ping my upnp server). The thing that does not work is that on the Raspi client it does not find the upnp server. I can ping the server but kodi for example can not find it. On the other clients it does work. VLC for example can find the server on these client's but only when i set the allowed addresses to 0.0.0.0/0. I guess that this some routing thing or the way that a upnp server works.? So i did the same thing on the pi but still it can not find the server. But ping is still working. I was wondering if this could be because i connect the pi via wifi? Maybe someone has an idea. Thank you for your help.

I currently use an mpd with 4 configured outputs, wired to speakers in the ceilings as home-made "multiroom" audio system. I would like to add wireless speakers, e.g. one like this . The question is: How can I tell mpd that there is an output which is in fact remote a dlna/upnp (even aiyplay would be fine) ip-device ? Is it possible at all ? **Edit 1:** I found a way , though through pulseaudio and not dlna (which could be a use for one of my Raspberry Pis).

I have a MiniDLNA + Bubble UPnP Server running at home and I would like to access it remotely from my PC at work. I can check that the server is properly accessible though the Bubble UPnP App for Android, where I can enter the URL to my server. There is a wide range of UPnP client software for Linux, but non of them offers the possibility to enter an URL, which is quite hard to believe. During my search I checked all of them listed here on wikipedia , and all of them just search the local network for servers. Does anybody know a UPnP client / controller software which can deal with remote servers?

I have seen that I can use miniupnp to apply port forwarding on my router, and I would like to find another tool to apply DNS and/or DHCP settings on the router. Is this possible? My goal is to have a script that once executed, it configures a VPN and DNS on my server, and also configures the router accordingly ( VPN port forward and DNS pointing to my LAN server ) without any user intervention. Thank you for your help! **Edit::** I have found an interesting python tool that can help me discover UPNP devices on my network and also the UPNP services they provide. I have also understood that I need theLANHostConfigManagement UPNP service in order to modify DNS and DHCP settings on the router. Unfortunately neither of my 3 router devices provide this service, and for obvious reasons. I have understood the risks to allow for such devices for an app to change such settings. But then is there another way how/work around to achieve this convenience? My goal is to have a Raspberry Pi running PiHole or AdGuard Home (DNS) and that can be easily installed in a home network. Is there a creative mind that think of and show me of a way to automate DNS configuration without having the user do it himself, while keeping it safe and local?

This question is probably related to: https://unix.stackexchange.com/questions/19060/fedora-firewall-with-upnp Because newer fedora workstations use firewalld, it's a bit of a different situation. The problem I'm experiencing is that I can't reliably detect UPnP servers with my fedora workstation unless I disable firewalld altogether. I tried adding 1900/UDP to my active zone as well as the service upnp-client (which is the same thing). On the server side of things (gerbera), I only opened 1900/UDP and 49152/TCP - this is detected in an instant when the firewall of the client is disabled. I don't think that the server is at fault as all the other devices do not show up either when firewalld is active - except my router for some reason. (Also, sometimes gerbera showed up after some time without me changing the firewall settings of my workstation). Wireshark gets me this:

Imagine a standard desktop computer. Connected to this computer is a pair of loudspeakers via common 3.5 mm stereo jack (AUX). Everything works fine so far. ---------- Now we have a further speaker in another room of the building that does support receiving of UPnP-streams. How can I configure a Debian-based system to keep emitting the sound on the classic stereo jack **but additionally also stream it via** UPnP, so I can feed both speakers simultaneously?

In home networks based on modern routers supporting UPnP, torrent clients just work: they ask the UPnP gateway to open a port for them when needed. Yet, every guide I have seen about setting up a web server includes steps which manually enable port forwarding on the router. Why aren't web servers using UPnP for this purpose? Is there a technical limitation preventing them from doing so? To make the question less open-ended, how do I configure Apache to use UPnP?

My goal is to have my linux server appear as custom device in Windows' network view, just like routers and printers appear there (with panel URL, version, support links etc.). I believe it is done via UPnP but I couldn't find any resource on how to actually accomplish this. Everything I've found so far was how to host the UPnP server which isn't what I want to do.

I installed firewalld on my Debian 10 laptop. Now Transmission cannot upload properly. If I go in to Edit->Preferences->Network and click [Test Port], it says the port is closed. If I systemctl stop firewalld and restart Transmission, then it says the port is open. How can I use Transmission with a firewall?

I'm using Fedora 15 and Transmission BT client. Transmission can't open ports unless the firewall is disabled. I searched some posts that said add 1900 to the trusted ports, or via a iptable rule: -A INPUT -m state --state NEW -m udp -p udp --sport 1900 -j ACCEPT". However, Transmission can't open ports anyway. I also tested with upnp-inspector, which is better than Transmission, it could detect my upnp router after add 1900 to the trusted ports, but the detection is slower than if the firewall is disabled. Any ideas on how to let Transmission UPnP works with the Firewall?

I have a server which, amongst other things, serves media over DLNA (UPnP) using mediatomb. Clients use *Simple Service Discovery Protocol* (SSDP) to locate the server on the network. I found that the SSDP discovery M-SEARCH queries were not being responded to and eventually tracked the problem down to the fact that the server was using a bridged interface which had *multicast snooping* enabled (because bridges have this enabled by default). I fixed my problem with echo 0 > /sys/devices/virtual/net/br0/bridge/multicast_snooping However, although this works in my situation, I don't understand what it's doing and if there are any implications that I am unaware of. Hence the question.... What is multicast snooping, why does it break SSDP, why it would be wanted and why it is enabled by default on a bridge, and what problems may be caused by disabling it because It's presumably enabled by default with good reason ?

My computer is connected to a router that supports UPnP, however it's not the last router on the way to the WAN. So, mapping there has no effect. I've got VPS and I've made a VPN network (computer VPS). Now I've got two gateways, but GW using tunneled interface has lower metric, so everything goes through it. I want to check whether some certain software maps (creates forwarding) for any port using UPnP. I want to monitor any event regarding UPnP (router discovery, port mapping request, etc.)

I'm a long time fan of Slackware and I've always had a machine serving as my main server/firewall with the latest version installed. I have it now but I'm struggling to find information on how to setup UPnP on it. Can anyone please provide some good links where I can investigate further?

I'm trying to run Rygel , a UPNP media server, on a headless Fedora 20 system. I installed Rygel, and created a dedicated user and systemd unit for it. Rygel starts but it is not listening on the port I asked it to. I think this is because it fails to get a list of network interfaces from NetworkManager. How can I give it permission to talk to NetworkManager over DBUS? **NOTE:** Both NetworkManager and dbus-daemon are confirmed running.

If we add a device that does not support PNP (Plug-an Play), the manufacturer will hopefully provide explicit directions on how to assign IRQ values for it. However, if we don't know what IRQ value to specify, what command line should be used to check if a IRQ value is free or not? lsdev displays info about devices: $lsdev Device DMA IRQ I/O Ports ------------------------------------------------ 0000:00:02.0 7000-703f 0000:00:1f.2 7060-707f 7080-7087 7088-708f 7090-7093 7094-7097 0000:00:1f.3 efa0-efbf 0000:01:00.0 6000-607f 0000:04:00.0 4000-40ff 0000:05:00.0 3000-30ff acpi 9 ACPI 1800-1803 1804-1805 1808-180b 1810-1815 1820-182f 1850-1850 ahci 43 7060-707f 7080-7087 7088-708f 7090-7093 7094-7097 cascade 4 What about this cmd lsdev, is it enough for this task? For example, if we want to know if 1233 is free, we would run this command: lsdev | awk '{print $3}'|grep 1233 **NOTE:** $3 above is used because IRQ value printed in the 3rd column of lsdev output. Then if no output, it means that it is free for us to use?
