Sorceror 0 Posted October 7, 2018 Share Posted October 7, 2018 After update to 3.5.3.0 version the DLNA server is not discoverable. I'm not sure but the previous version was about 3.2.x I have emby server installed on 18.04 Ubuntu system which is used as server/router.So there are two interfaces 192.168.2.1(local network) and 10.5.214.16 (external network) There is no error message in the server log and the server is binded to the 1900 port.netstat output:udp 1574 0 0.0.0.0:1900 0.0.0.0:* 13240/EmbyServer When I try to "find" the server using DLNA client I can see my request from the local network:[uFW AUDIT] IN=enx801f02d62380 OUT= MAC=80:1f:02:d6:23:80:d8:cb:8a:13:fb:0f:08:00 SRC=192.168.2.120 DST=192.168.2.1 LEN=32 TOS=0x00 PREC=0x00 TTL=128 ID=16239 PROTO=UDP SPT=59263 DPT=1900 LEN=12There is also blocked multicast because external interface ports are blocked:[uFW BLOCK] IN=eth0 OUT= MAC= SRC=10.5.214.16 DST=239.255.255.250 LEN=174 TOS=0x00 PREC=0x00 TTL=4 ID=1793 DF PROTO=UDP SPT=36376 DPT=1900 LEN=154 Should not there be also a local network multicast? Even when firewall is completly disabled the DLNA server is not visible on my local network. Link to comment Share on other sites More sharing options...
Luke 36997 Posted October 7, 2018 Share Posted October 7, 2018 Hi, what is the value of your server's dlna alive message interval setting? Link to comment Share on other sites More sharing options...
Sorceror 0 Posted October 7, 2018 Author Share Posted October 7, 2018 Hi,the alive message interval is now at 1800s which was default value but I also tried values up to 30s. The client discovery interval is also set to 30s Link to comment Share on other sites More sharing options...
Luke 36997 Posted October 8, 2018 Share Posted October 8, 2018 You could try lowering it to 30, then restarting the server. Link to comment Share on other sites More sharing options...
Sorceror 0 Posted October 8, 2018 Author Share Posted October 8, 2018 Interval set, server restarted, but no change. I tried also 10s just to be sure. Link to comment Share on other sites More sharing options...
Luke 36997 Posted October 9, 2018 Share Posted October 9, 2018 Maybe it has to do with the blocked multicast? Link to comment Share on other sites More sharing options...
Sorceror 0 Posted October 9, 2018 Author Share Posted October 9, 2018 Unfortunately it is not working even when the firewall is disabled or when the multicast is unblocked. I posted current settings but i tried to allow external port 1900 or to disable firewall.I am not sure how it really works but the only communication with destination 239.255.255.250 is from my external interface. Should not there be also a local network variant? Or it would be great if i could configure DLNA to listen and communicate only on specific interface.

ghost2015 1 Posted October 15, 2018 Share Posted October 15, 2018 (edited) Hi, there is a problem with dlna server on my installation. I'll try to describe my configuration I have server with 3 network adapters first one is on my local network 192.168.11.0/24 eth0 second connects to remote file servers 10.10.100.0/24 eth1 and the last one interface with real ip 158.255.*.* eth2 when system configured with only one network interface (eth0) then all work fine.. DLNA appears on all my devices and can scan TV, AV... as client ( Play on...) If I configure second interface or all three interfaces dlna stop working on any interface at all... but netstat output says that DLNA listening port 1900 tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 :::8920 :::* LISTEN tcp6 0 0 :::8096 :::* LISTEN udp 20480 0 0.0.0.0:1900 0.0.0.0:* udp 4928 0 0.0.0.0:7359 0.0.0.0:* udp 44800 0 0.0.0.0:44011 0.0.0.0:* how to resolve this issue ?

Luke 36997 Posted October 16, 2018 Share Posted October 16, 2018 Looks like you went back and forth between beta and stable. Please be aware this is not supported. At this point you will either need to go back to the beta version, or do a fresh install of the stable version. Thanks. Link to comment Share on other sites More sharing options...
ghost2015 1 Posted October 16, 2018 Share Posted October 16, 2018 Hi Luke, you are right. It was an experiment, i tried beta version and then rollback to stable, my mistake now I have test clean installation, but DLNA is not working when 2 or more network adapters configured. logs with one and two adapter in attach after install with one network all works perfect DLNA shows on any device and work after I add second network - no DLNA server on any interface Log-1eth.txt Log-2eth.txt Link to comment Share on other sites More sharing options...
Luke 36997 Posted October 16, 2018 Share Posted October 16, 2018 Ok, at the moment I'm not quite sure of the issue as it seems to be working fine in our testing. We'll continue to investigate. Thanks. Link to comment Share on other sites More sharing options...
ghost2015 1 Posted October 16, 2018 Share Posted October 16, 2018 If it will help I can make virtual windows 7 desktop for you and root access to test emby server from virtual desktop ) Link to comment Share on other sites More sharing options...
Luke 36997 Posted October 17, 2018 Share Posted October 17, 2018 Well I have a windows 7 system for testing. How would this be different? Link to comment Share on other sites More sharing options...
ghost2015 1 Posted October 17, 2018 Share Posted October 17, 2018 This will be my current installation on my network with DLNA problem real server vs real situation vs real logs and full access Link to comment Share on other sites More sharing options...
Sorceror 0 Posted October 17, 2018 Author Share Posted October 17, 2018 (edited) Hi,I have been away from the computer lately. There is my latest server log file.But according to other reported issue it seems to me it is indead problem with multiple interfaces.So I disabled my external interface to test it. It is USB->LAN adapter so I just pull it out and now with only one interface DLNA is working again.Could it be that DLNA service is using only the default interface to "respond" even if it is listening to all interfaces?Either way it would be best if we can select the specific interface for DLNA as well as we are able to choose the interface for HTTPS. embyserver.txt Edited October 17, 2018 by Sorceror Link to comment Share on other sites More sharing options...
