I was doing some work... (and then I got cut off)

on pcp and dslite, and that may have crept into the relevant packages by mistake.

It certainly wasn't ready for prime time, so if it escaped, I'll fix it.

But aside from that I don't actually use these packages at all, nor do I have automated tests. What exactly is breaking?

I usually pull these packages from this build:

https://forum.openwrt.org/viewtopic.php?id=27722

Arokh doesn't use the in tree openwrt packages, I know he uses miniDLNA cvs for example.

For UPNP/NATPMP you only need miniupnpd.

MDNSresponder isn't needed for anything anymore (as far as I can tell). I think Avahi replaces it.

To get MiniDLNA and miniupnpd to work together (they use the same ports), you use minissdpd to manage that.

Basically, I start with Arokh's tarball as a base, and then apply CeroWRT patches on top of that.

miniupnpd is running on port 5000 by default (http://wiki.openwrt.org/doc/uci/miniupnpd)
minidlna is running on port 8200 by default

[b]update: looks like minissdpd might really be required for these 2 to work, because of UDP 1900, not the TCP ports...[/b]

• netalyzr has a check for that
• utorrent has a built-in checker if it can negotiate with the router to open a port
• other PNP/SSDP test programs like: http://www.junegillespie.plus.com/UPnPTest.exe

• Run Windows Media Player 12+ (or any other DLNA device, like a TV) and see if it shows your DLNA under "Other Libraries" and if you can stream a video or a photo (provided you gave minidlna something to index

I am going to updated to latest cero, install these 2 packages and try describe what's wrong with packaging because I believe the daemons should work, it's just getting the scripts to start properly and read right config files and stay daemonized.

Arokh doesn't use the in tree openwrt packages, I know he uses miniDLNA cvs for >example.

Although I have been pulling multiple packages from unstable sources, I'd like to do that less, not more.

For UPNP/NATPMP you only need miniupnpd.

OK.

MDNSresponder isn't needed for anything anymore (as far as I can tell). I think >Avahi replaces it.

Avahi does, although I currently don't have the router issuing multicast queries to itself, but using the local dns.

To get MiniDLNA and miniupnpd to work together (they use the same ports), you use minissdpd to manage that.

I don't build that currently...

Basically, I start with Arokh's tarball as a base, and then apply CeroWRT patches >on top of that.

Call me lazy, but if you can package that up and give me a tarball of the package(s), that would be great. Better, I can give you commit privs to the ceropackages repo.

Let me...

I note that I don't have a problem in pulling something that works from an unstable source, if that's the way to get it to work. I'd merely prefer to pull something that works from a released tarball, if at all possible.

When I get the chance I'll look at adding these packages to cerowrt.

I think by now the in-tree openwrt packages do work, so I'll attempt
to use them as a base.

There's a cerowrt tarball I can work with as a base? It's been a while
since I've worked on the cerowrt base. I've being using arokh's builds
and picking and choosing bufferbloat patches.

The only thing I use Avahi for is to announce time machine/ftp/ssh
servers. I'm not really sure it's necessary to make minidlna/miniupnpd
features work.

A caveat is that miniDLNA can use a good chunk of RAM, especially if
you have BIND running still.

It seems to work fine for me, but I'm using chrony rather than
ntp-client, and dnsmasq rather than BIND, which cuts down on RAM
usage.

What is a good way to test the functionality of these packages?

Hi!

2) UPNP / NATPMP / mDNSresponder - to help different apps reaching out - i am sort of losing grasp of which package does what, they seem to be intertwined (?) but cero has these packages currently (3.3.1-4) broken. 3) miniDLNA - DLNA is a good low-latency (?) / high-throughput use-case within the wireless (laptops, picture frames) and wired (TV, NAS) home network. Also minidlna package is broken too.

Update. I've installed minissdpd, miniupnpd and minidlna-cvs from trondah (http://enduser.subsignal.org/~trondah/latest-release-is-r31219/packages/) and they work. All I needed to correct were the interface names in /etc/config/... to include se00,sw00 and sw10. If proper starting sequence is respected it works: minissdpd, then miniupnpnd, then minidlna.

If I knew how to add these packages to the build, I'd do it.

There's one issue with it though. When my TV is on se00 and my laptop on sw10, they can't discover each other as UPNP queries are broadcast-domain-bound (won't traverse NICs) - so the network fragmentation plays in my disadvantage here. I still need to poke around to see if there's anything I missed or maybe I could use iptables to DNAT it to the other interfaces.

Having said all that, I still need to evaluate performance of minidlna on WNDR3800 and how much memory/cpu stress it could cause with 30.000 files. Unfortunately I can only check with a NTFS drive promptly. Converting it to ext4 is tricky as I don't have enough storage space handy that would allow me to do it quickly enough.

Anyway, this is mostly DLNA talk. If that wouldn't make it into cero, I could live with it, but I'd still like to see miniupnpd for UPNP assisted port forwarding negotiation and since it would be good for the build to allow users to install minidlna externally, minissdp would also be very nice to see (as per the dependcy Hector mentioned)

I'll try to make anything work. But does he have his source packages somewhere?

As for the crossing broadcast domain issue, I'm always into finding those and figuring out how to fix them...

That's his source.

http://enduser.subsignal.org/~trondah/releases/r31216/openwrt-r31216-src.tar.bz2

As far as performance of MiniDLNA, it will use a lot of disk seeks and CPU while it builds its database. But otherwise it mostly sits idle, and serves up files on demand. I personally have a swap file enabled since I hits the limits of the 64MB of RAM.

Please send me cero-specific conf files? and tell me which package sets to use? Openwrt? the other guys?

Also, I have a user reporting that upnp doesn't work the way he expected in that he wanted to open port 22, gets 2022 on both sides, and I don't understand the requested behavior...

I assume the idea is to map <external>:22 => <internal>:22. Since that possibly clashes with the internal sshd, I'd naively expect it to map <external>:2022 => <internal>:22 instead (you don't get the external port you wanted, but a mapping does exist). If it's changing the requested mapping to <external>:2022 => <internal>:2022, that's a bug.

Hi, sorry for no update. I was travelling. I will redo from scratch with latest cero build and document the packages and configs.

Add https://dev.openwrt.org/ticket/8988 along with the appropriate config changes?

Yes, trondah's minissdpd, miniupnpd with config changes are what we need.

I also found one thing here. DLNA does not work on cero between a wireless and a wired peers because FORWARD chain needs to let UDP 1900 through for SSDP multicasts and in the case of PS3 media server also TCP 5001. Anyway, FORWARD chain is a bit restrictive.

I would like to fix this somehow before the next release.

what is the current status of the in tree vs out of tree code?

For UPNP this is required. I tried a git commit today but I'm not familiar
with git that much.

This patch uses cero iface names. Listens only on 'secure' interfaces such
as ethernet and non-guest wlans.
