minidlna from one server not being spotted

Question

I have minidlna set up on two servers on my subnet. One [serverA] is found by the other server [serverB] and the tv. The other [serverB] is not picked up by either other device. A quick check with both netcat and curl show the other device and port 8200 accessible, i.e. both:

 curl http://10.0.1.112:8200

and

nc -zv 10.0.1.112 8200

are successful. Additionally, I have also enabled allmulti and promisc for eth0 on serverb as per [here].1

Not sure how to proceed.

Answer 1

I got it working by doing two things:

1. Upped the announce rate - changed the notify interval from 900 to 90 in /etc/minidlna.conf, i.e. notify_interval=90

2. Added a multicast route.

   route add -net 239.0.0.0 netmask 255.0.0.0 eth0

   ifconfig eth0 allmulti multicast

I also tried a few other seemingly legitimate changes to /etc/minidlna.conf but they caused things to quit working.
