DSM-G600, DNS-3xx and NSA-220 Hack Forum

If you got debian on your dns-323 you should see multicasts like this if you do a tcpdump:

09:12:57.923899 IP TECRA.5353 > 224.0.0.251.5353:  0 [2a] [4q] PTR? _appletv-pair._tcp.local.[|domain]
09:12:58.790241 IP TECRA.5353 > 224.0.0.251.5353:  0*- [0q] 3/0/0[|domain]

I very strongly doubt that there is an issue on the DNS side. However either your firewall/router is acting up or there is somekind of fw software running on your pc...

ill give that shot and report back the findings

cheers

Fickle,

My Firefly works when I do a cold re-boot of the 323. I can see it in iTunes. I can play from it. BUT...when I access it from my MAC iTunes, or add a CD to the 323 (via iTunes) the server stops.

I have something from Ron Pedde to try to see if it is the Firefly server stopping or if it is the network doing something. Unfortunately I have to install Debian to execute the commands. This is a challenge and will take me a couple of nights to get my head around. You may want to try it. This is the instructions from Ron:

When it appears when it first starts but then disappears later, that's
almost always (well, unless the server crashed) multicast issues.

What's the model on the wireless router?

When it disappears, you can check to see if it's still running from
the console of the dns-232 with something like this:

ron@debian-server:~$ ps auxw | grep -i "mt-daapd"
nobody 2536 0.1 4.0 4096 1228 pts/0 S 22:15 0:00 /usr/
sbin/mt-daapd
nobody 2537 0.7 5.0 8192 1556 pts/0 S 22:15 0:00 /usr/
sbin/mt-daapd
nobody 2538 0.0 5.0 8192 1556 pts/0 S 22:15 0:00 /usr/
sbin/mt-daapd
nobody 2539 0.0 5.0 8192 1556 pts/0 S 22:15 0:00 /usr/
sbin/mt-daapd
nobody 2540 0.0 5.0 8192 1556 pts/0 S 22:15 0:00 /usr/
sbin/mt-daapd
ron 2542 0.0 1.5 1552 460 pts/0 S+ 22:15 0:00 grep -i
mt-daapd

You can see five processes running mt-daapd. That's what it looks
like when it's running. Otherwise, it would look like:

ron@debian-server:~$ ps auxw | grep -i "mt-daapd"
ron 2542 0.0 1.5 1552 460 pts/0 S+ 22:15 0:00 grep -i
mt-daapd

So you can verify if it's a network issue or the server crashing by
seeing if it's still running when it disappears off the network.
Unless you are running a very recent nighly, my bet is on the network.

i have yet to do the cold reboot. i will give that a shot tonight

may have to look into the debian thing as well, but im no linux guy

You don't need a debian install to check if the mt-daapd server is still running

The 'ps' command is available from the busybox v1.6.1 binary in fonz's v.03 fun_plug

Type the 'ps' command that Ron Pedde suggested from the telnet prompt
to see if the mt-daapd server is running.

Thanks for that...
Right. Have done it and this is the response. Have sent it to Ron to get feedback...if you can see anything....many, many thanks:

Ron,

This is the response when it is running:

1330 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1331 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1360 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1361 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf

This is the response after it stopped:

1330 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1331 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1360 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1361 root    /mnt/HD_a2/lnx_bin/mt-daapd -c /mnt/HD_a2/lnx_bin/mt-daapd.conf
1480 root    grep -i mt-daapd

So....there were four running at the beginning and five after it fell over.

Don't know what this means....

Drew

Thanks Mig. That means that the Firefly server is still running and it is a network issue....OR could it be that if the Firefly database is changed or accessed by another computer on the network it becomes corrupted (in some way)? I think this is probably not the reason.

More than likely it is the network not doing multicast properly - that is Ron's suggestion - even though the DNS-323 is now set to promiscuous multicast.

I am using a DLink DSL-604T router/modem. This is where I thought the problem was three weeks ago....and I guess this confirms it.

And so the journey to getting this working continues....

glad to see you got yours working Drew, now my turn. been out a few days so now i need to catch up .. will have to look into my router for IGMP .. though i dont think i saw a setting for it anywhere on the router.. but i will have a 2nd look

cheers

hey Drew,

its an Linksys WRT350N (technically i have two routers, the other is a Cisco 1751) but i am sure this is not the issue, i would think its my linksys.. .. my cisco is only used for NATTING externally to internally ... my linksys is to connect local devices.. then off to the cisco for internet access

cheers

jeez drew, you drew up more on my router than i could find within the help manual

i do recall some of the stuff you mentioned, and yes, somewhat .. difficult to understand

ill run these commands tonight and modify my router accordingly

stay tuned

and thanks

Well...your Firefly server is running. So that is good.

When you do a complete shutdown of the 323 and then restart - does the Firefly server appear in iTunes? If it does, and then disappears, this is pretty much as conclusive as you can get that it is a network issue and multicasting isn't working as it should.

One other thin I noticed in the router is that you have the ability to turn on UPnP and have the router act as a media server. I would try changing the settings in this tab. UPnP turned on - then off - remembering to do a total shutdown in between each different setting you try. I think it is important to shutdown completely and restart. Try UPnP on, and the media server off - I think you can do that as well in the UPnP tab (from memory it is @ page 36 of manual).

Best of luck....

swapped out to a different router, still same issue. this is an older router with very little functionality in respect to firewall. i have removed or disabled any firewall rule within this old router and still the same issue arises.

i do agree that it is not the 323 that is the issue (based on trouble shooting from prior posts .. thanks Drew), just cant identify what the real culprit is..

the search goes on

did you manage to find out about the issue?

Thanks!
