Sinology reconnect

[pisuke74]

Hi. I've configured nas synology as upnp. After scan.. Works but after a while the synology disappear. I have to do a remount and a new rescan.. Where s the problem? Thanks

Just saying "it doesn't work" is not going to be enough to troubleshoot your issue.

[pisuke74]

right Tim ..

so if i configure as a smb network moodeaudio identify my sinology..but after a while (scan a letter and b letter...) stop scan...

i ve tried upnp but have the same problem

via smb it's mounted at restart.. but only with 2 folder scanned

on sinology it's configured to accept smb 1 to smb 3

It sounds like some sort of network or NAS configuration issue. I don't own a sinology NAS so I'm not going to be able to help but maybe another Synolog user will reply.

[pisuke74]

thanks. i will wait a synology user

In the meantime you could try some basic network diagnostics.

1) Run a 30 second ping test from the Pi to your NAS and see if there are any errors or %packet loss in the ping stats. Below is an example from one of my Pi's to my Router which also functions as a NAS.

Code:

pi@rp3:~ $ ping rt-n66u
PING rt-n66u.home (192.168.1.1) 56(84) bytes of data.

2) Examine the stats for the network interface on the Pi and see if there are excessive number of retires or dropped packets. Example below from one of my Pi's using WiFi (wlan0)

Code:

thanks

all test done. no errors

[Tim Curtis]

Thats good :-) Prolly can rule out network.

Here is the command for the Samba scan

Code:

sudo smbtree -N -b

[pisuke74]

after this command nothing happens

[Tim Curtis]

That suggests several possibilities including (1) SMB broadcasts are being blocked by some network device or (2) the NAS is not advertising its Samba shares or (3) something else on the network is blocking SMB protocol.

You could try using the IP address of your NAS instead of its host name when creating the NAS config in moOde. If there are still issues then I would suspect something on the NAS.
