just tried this by modifying the /etc/default/logitechmediaserver and
LMS did bind to 192.168.1.23.
but again, i had no trouble accessing and playing local music via
desktop browser (of course it has the hotspot nearby).
strange thing is there at the pi itself, there was no audio!
despite the fact on the browser, LMS shows a track is playing

so ultimately i believe this is a networking issue, more specifically
one of the default gateway.
as long as the wifi hotspot is available (and its default gateway),
everything works.
but one would think that LMS with a locally attached music should be
able to play without internet.

you have sized up the situation correctly and thus, your questions are
exactly mine.
that in itself is some consolation.
i would have thought my situation would be quite common (at least not
uncommon) given all the purported cord cutters.

at this point, i've concluded it's a networking issue in raspian9 and
pursue that line,
not necessarily any flaws in squeezelite or lms.

thank you for your thoughts and feedback...

tried it already with both localhost, 127.0.0.1, even 192.168.1.23 (with
LMS set to 192.168.1.23)
same behavior:
all works fine via desktop browser interface 
but not locally at the pi itself.

of course, dr. murphy is active today, even when i take the mobile
hotspot down to the remote corner of the house,
wifi is strong and the pi is able to connect, weakly but still connect.

at this point, my issue is academic but i'm sure curious as to why and
how this gateway thing works or not work

apparently, with Raspian 9, /etc/dhcpcd.conf is used rather than
/etc/network/interfaces
as stated before, specifying "any" gateway for eth0 renders wifi to not
function at all.
when the pi connects to the hotspot, wlan0 gets its gateway assigned to
the hotspot and all's ok.

as for 192.168.1.23, it is used by any other device on the lan; e.g.,
windows desktop and laptop with ethernet cables so that
i can ssh into the pie.   and of course, i can use the browser to view
LMS.

on the browser, i connect to LMS using 192.168.1.23:9000.
that's the static ip addr of raspberrypi's eth0.
LMS shows only one player, squeezelite, at 127.0.0.1.

i didn't expect jivelite to be doing any network requests. it's just UI
for squeezelite.
that's why i'm picking on squeezelite.
tried to turn on debug but of course, it doesn't work. i specified the
-d log=debug option for squeezelite but
the log file is empty. but of course...

naturally i want to keep things simple; i.e., neither 4g router nor pi
as a router.
consider this:
i boot the pi without wifi, only eth0 (without gateway), and using
desktop browser over lan, all works as expected.
so browser is really a functional equivalent to squeezelite running on
pi.
why is squeezelite having trouble to connecting to a localhost server?

i tried this.  kill squeezelite.  verify LMS is listening on 127.0.0.1.
started squeezelite with specific arg -s 127.0.0.1.
still it can't connect!

i believe i mentioned this before.
i can add a "dummy" router to the lan, assign it as the gateway. then
squeezelite works!
BUT when the hotspot comes around, it won't work; i.e., no internet
access.
it seems to be an either/or situation.
and clearly a networking issue within raspian.

i've posed a similar question on the raspian forum and hopefully
some network gurus can help...

d6jg/DJanGo,
yes, my networking knowledge is limited but not at zero level.
please consider these points:

- ALL devices connect to internet via the mobile hotspot. i was very
pleasantly surprised how well this works, as they say seamlessly.
- even lan-connected (i.e. ethernet wired) devices use the hotspot for
internet, so the raspberryPi does not have to be a router, bridge or
access point.
- lan is strictly private and used for direct connections to local
devices, such as, printer, raspberryPi and local network storage.
- without the hotspot, via a browser over lan connection, i have no
trouble connecting to LMS and playing its local music.
- THE (and only) problem is that at raspberryPi itself (it has a local
display managed by jivelite), if i attempt to play music, squeezelite
cannot connect to LMS!

how idiotic is that?
LMS is bound to 127.0.0.1 and the player, squeezelite, is told that its
server is at 127.0.0.1.
and they can talk to each other? 
apparently, they can since as i said, i can play music if i use a
desktop browser
but not at the pi itself.

that is why even a networking neophyte says 
it's gotta be software, specifically squeezelite since it is the
component that's failing!
but why?

time to leave networking and pick on squeezelite

usb works wonderfully and simple to implement on LMS.
i use winSCP from the desktop.

my hotspot is provided by t-mobile. i did not know about data sim.
can it coexist with the cell sim?

as i recall, i built jivelite from scratch (via
https://github.com/ralph-irving/triode-jivelite.git).
surely i shouldn't have to do it again.  
isn't there some magical config file that would tell jivelite to use lan
instead of wlan?

thanks for that.
i was reading the doc wrong.
here's what the log says:

[14:46:50.504244] slimproto:883 connecting to 127.0.0.1:3483
[14:46:50.504824] slimproto:908 unable to connect to server 0

[14:47:00.505734] slimproto:922 connected
[14:47:00.505918] slimproto:933 local player

questions:
1. is server 0 at 127.0.0.1?
2. is 3483 special port for players?
3. so did it eventually connect?  it says "connected".

over at jivelite forum, bunch of people were talking about this!
how did you uninstall/reinstall jivelite exactly?  'cause i made it some
months ago following http://hagensieker.com/jivelite/index.php
instructions.

snooping around the .jivelite directory, i found SlimDiscovery.lua which
had the following line:
{serverInit={ip="192.168.43.252",}
that's the wlan0 address which the hotspot dynamically assigned.
of course, when hotspot goes away, this addr is no longer around.
so i changed it 127.0.0.1 or 192.168.1.23 but neither worked.  jivelite
fails to connect to LMS.
do i need to somehow compile this .lua file?

when i took the mobile hotspot near the pi,
this file magically returned to what it was, 192.168.43.252.
i assume jivelite is doing this but why and how?

yes, i was over at the jivelite forum and it seems some folks had a
similar (but not quite mine) situation where they removed the ethernet
connection, began using wifi and then, jivelite would fail to connect to
lms.  common solution was re-installation or reset with wifi present.  i
was about to follow suit but now believe it would be futile in my case. 
as you point out, problem is jivelite's persistence for wifi. even after
hotspot goes away, it retains the wifi address, so of course, it cannot
connect.  yes, it should be able to handle the simplest configuration
where all are co-resident in the same machine!

as for trying out a 'dummy' dns server, i will look into using a local
router if it can be set up as such.
otherwise, do you know of a windows10 software that can do this quick
and dirty?

thanks guys for your valuable, thoughtful ideas!
d6jg/BosseJ, let me mull over your suggestions but for now,
i 'seem' to have come up with a working solution.

1) plugged in an old linksys router (running dd-wrt) and gave it
192.168.1.1 lan addr.  i did this once before but hated the idea of it
being ON all the time.
2) specified this to be the gateway/router for eth0.  previously this
was a serious problem since when hotspot was nearby, it would not be
used; i.e., no internet and could not stream spotify.
3) solution for #2 was to specify "interface wlan0 / metric 100"
(suggested by epoch1970) in /etc/dhcpcd.conf indicating that we prefer
wifi over wired interface.  with this, now when hotspot appears, pi has
internet access.

and the setup is working out for now... but the questions remain:
1) why can't jivelite deal with the simplest setup of all components
being in the same box? why not default to localhost when any connection
fails?
2) how can i get rid of the linksys router, a 'dummy' gateway?  
3) jivelite being UI for the player squeezelite, why is it talking
directly to LMS?  i imagined the design was
jivelite<-->squeezelite<-->lms.

[SlimDevices: SqueezeCenter] IP addr assigned to LMS

[pavowren]

hello,
i have been looking into this issue for couple of weeks now and feel i'm
at least zeroing into it.
here's the setup:
- LMS installed on a raspberryPi3B+ along with squeezelite and jivelite
- media is local at /mnt/usb
- ethernet connection and wi-fi via a mobile hotspot

problem:
when hotspot goes away, My Music fails attempting to connect to
"raspberryPi"

observations:
- as expected, i have no problem connecting to LMS from a local browser
via http://192.168.1.23:9000/
- BUT it has the old ip addr assigned by the hotspot
Logitech Media Server Version: 7.9.2 - 1530185314 @ Thu Jun 28 14:19:19
CEST 2018
Hostname: raspberryPi
Server IP Address: 192.168.43.252
- yet, via browser, all works including viewing My Music but not at the
raspberryPi itself (jivelite)

questions:
- how does LMS gets its ip addr assigned?  can i make it static to local
eth0 addr, 192.168.1.23?
- since all components are local to raspberryPi, why should ip addr
matter at all?
- lastly, how does brower access work as expected but local access does
not? very frustrating to say the least...

any insights would be greatly appreciated...

thanks folks for your responses!
first, let me clarify my goals and network configuration.
since i've recentlly cut the cord, my internet connection is via mobile
hotspot (galaxy s8+ running oreo 8.1).

- my raspberry pi 3b+ is running raspbian 'stretch'
- it has eth0 connection with static ip address, 192.168.1.23 specified
in /etc/dhcpcd.conf
- eth0 has NO router or gateway specification.  in fact, if i do specify
it, wifi will not work.  i read elsewhere that the system can have only
one gateway, so this make sense i suppose since when wlan0 gets its
dynamic address from the hotspot, it also gets its gateway assigned as
well.
- my LAN has no router or switch. desktop, laptops and the pi all use
the powerline ethernet adapters, so it's simply a backbone with no hub.
i have already tried putting in a physical router but to no benefit.
- when hotspot is available, pi always gets assigned 192.168.43.252 and
everything is beautiful. spotify streaming works and i can play music
stored on the usb stick attached to the pi.
- jivelite is the interface to the soft player squeezelite, and this is
"My Music" i was referring to.

BUT here's the problem:
- when i take the hotspot away (to downstairs to work on the desktop),
of course as expected, i cannot stream spotify.
- but i should be able to play local music (it's on a usb stick plugged
into the pi itself), but cannot.  when i click on My Music icon, it
displays that spinning wheel and the statement "Connecting...  to
raspberryPi" or something close to it.  and it times out eventually.

so my goal is to be able to move the hotspot away and still be able to
listen to local music.
when hotspot returns, spotify and internet radio all work as expected.
not a huge deal but still irritating... and i keep thinking it should
just work!


i hope i have described the situation a bit better this time.
tomorrow, i will ssh into pi and provide the routing info.

Paul, your idea about --httpaddr 192.168.1.23 is something i wanted to
try.
'cause LMS has the "old" hotspot as its addr and now when the hotspot is
gone, of course it won't and can't respond.
do you happen to know where in Raspian the LMS execute command lies?

i'm curious how LMS decides to bind to wifi addr rather than the static
eth0?

yes, wi-fi certainly is not preferable to wired.
yet, the hot spot is speeding at around 3 mbps and i'd assume that is
more than sufficient for radio streaming 64kbps.
unfortunately, wifi hotspot is my only option to internet; recently i
got so irritated with the local isp, i cut the cord totally!

i'm thinking it's some kind of network configuration issue, just don't
know what.

player is set for "Direct Streaming" as it should be.
both the RPi (squeezelite) and NUC (LMS) are connected to the same LAN,
so of course, local music playback is fine.
it's just the internet streaming that's the issue.
when playing a radio station, sqzlite shows "Connecting..." 

problem i believe lies in networking.

ok, good folks, let me step back and paint a clearer picture.

OLD setup:
little RPi had everything on it; LMS, music on usb stick, SqueezeLite,
Jivelite, the works.
and it worked fine for a while. then, it started acting up in various
ways, e.g., LMS just stops playing, volume drops, hdmi display became
non-touch, etc.
so i decided to trim it all the way since i was buying a brand new Intel
NUCi7 kit.

NEW setup:
LMS runs on the new NUC with music on a SSD.
RPi runs squeezelite and jivelite.

Network-wise:
RPi and NUC are on the same LAN with a Linksys router (NO internet, i
cut the cord to Windstream).
RPi has no wifi now.
NUC has wifi connection to the mobile hotspot (T-Mobile) averaging now
about 0.6 Mbps (normally up to 20 Mbps) after using up my monthly
bucket. 

Wishlist:
be able to run both LMS and Roon on NUC.  
they have been successfully installed but there are

Issues:
1) Roon Bridge and SqueezeLite cannot coexist with the Allo DigiOne
output device.
if i stop SqueezeLite, Roon works; otherwise, it does not see it.
2) forgetting Roon for a moment, LMS has problems getting to
mysqueeze.com.
Firefox has no problems going anywhere including mysqueeze.com.
i've installed linux packages from the terminal without any problems.
so, i know the internet access via wifi works.
it would seem LMS is the only guy with issues.

i have pursued the network interface metric angle without success so
far.
any more ideas for me to try will be most welcome...

well, you are absolutely correct about RPi streaming radio directly, not
via LMS.
i re-enabled wifi and RPi has no problems playing internet radio!

however, if only i can get Spotty to install on LMS, i can test Spotify
which i'm assuming (confidently?) will be streamed by LMS.

thank you for your note!

All devices on LAN have static addresses including a Linksys router  
which serves as only AP, so that my phones and tablets can get to other
devices.

As shown below, default gateway on RPi is NUC (192.168.1.150).
but i've had it at Linksys. It didn't seem to matter either way. RPi
cannot get to the internet via NUC
which has the ONLY path to internet via the mobile hotspot.
Thus, my feeble attempts to "bridge" NUC's wired and wifi.

thanks for your persistence.
i am now pursuing your suggestion #1.
unfortunately, what i've learned that usb-tethering on t-mobile is quite
bad, speedwise.
someone complained of throttling down to 0.3mbps or something.

so, please give me some options for specific routers that can wirelessly
connect (for WAN port) to a hotspot.
or at least, some links where i can read up on this particular setup.
thanks to all for bringing up to this point; i'm not there yet but
believe on the right track.

well, networking sometimes works or not works in mysterious ways!
first the good news:
i was finally able to install Spotty; for whatever reason, it would
simply not stick.
i enable it on the plugin page and click to restart LMS, but it would
come right back unchecked but now, at the top of the page.
this went on all morning until just now.  
anyway, i can now stream Spotify (with no stuttering) from LMS with/out
wifi enabled on RPi.
yes, for radio, it does require local wifi on RPi as you pointed out
before.

bad news:
i need the hotspot for internet radio; was hoping to locate it in just
one place, near LMS.
so, what exactly did i do to make it work?
i really don't know.

i did change the metric (using ifmetric) for ethernet interface greater
than wlan but
that made things much worse.  i couldn't browse the net nor could i
connect to NUCi over LAN.
so i undid the change and now, the routing table looks like this:

groundie@NUCi:~$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse
Iface
default _gateway0.0.0.0 UG60000
wlp0s20f3
link-local  0.0.0.0 255.255.0.0 U 1000   00

eno1
192.168.43.00.0.0.0 255.255.255.0   U 60000
wlp0s20f3

and somehow, it all works.
being an ex-engineer, i wish i understood why.
perhaps you have an explanation...

n.b. as for the sim card, it is not a data-sim.  it is in the phone and
i certainly do not want to mess with it at this point.

ok, i have just ordered the WAP.
here's my current understanding:
my Linksys router will remain as it is in AP mode but now its WAN port
will link to the new WAP's ethernet port.
WAP will operate in client mode to the mobile hotspot.
now, all devices on LAN should have internet access.
does this sound right?

hi, just installed a brand new WAP, TL-WA801ND.
fairly quick setup for Client mode with static IP addr 192.168.1.2.
it connects to mobile hotspot successfully; i can see it listed on the
phone.
its ethernet port is directly connected to the WAN port of Linksys with
WAN connection type set to DHCP and LAN static ip addr 192.168.1.1

of course, all my local LAN connections work as before but
i am not getting to the internet via WAP.
i test this by disabling all wifi connections on my desktop and with
only the LAN wired connection, i can not get to internet.

there are few settings & behaviors i don't understand:
1) on Linksys, its status shows WAN ip addr to be 192.168.1.1 (its LAN
addr) despite the DHCP connection type. 
why is this?  shouldn't it get it from the attached WAP?
2) on WAP, i've tried to set its ip setting to what it calls "smart IP
(DHCP)" which i understood that it would be assigned one from the
hotspot.
but that setting didn't seem to help either.

hope you can shed some light...

well, i took a break, had dinner and came down to the office and noticed
WAP had disappeared from the hotspot.
it is not listed as one of the connected devices as before.  i only see
this desktop.
tried rebooting but made no difference.
may have to factory reset and try again...

wrt setting WAP ip addr to ..1.2, i did so for 2 reasons:
1) it allows me to sign into and see its management pages.
2) user manual stated something like this: 
"we recommend you configure this AP with the same subnet and subnet
mask, but different IP addr from your root AP/Router."

in any case, i set it ..2.2 and it did not make a difference.
but then, that's expected since it's not even attaching to the hotspot!
go figure...

earlier when it did connect to hotspot,
i saw it was assigned 192.168.43.170; hotspot itself is at ..43.1.

i'm going to try factory reset and start over...

[SlimDevices: SqueezeCenter] Only streaming from Internet is not working; all else ok.

[pavowren]

hello,
recently i removed LMS (and its local music on usb stick) from obviously
overloaded raspberryPi.
now, LMS v7.9.1 is running on the new Intel NUC i7.
rPi and NUC are on the same LAN.
NUC is using a wi-fi hotspot for internet access.

rPi streams local music just great.
however, internet radio is not streaming; just says "Connecting..."
forever.
despite the fact on the LMS web page, everything looks fine; the radio
station data is shown and clock is ticking.
it would seem LMS and rPi are not talking once the streaming begins...

when i had Spotty plugin working, Spotify playback was constantly
"Buffering..." and of course, sound was stuttering a lot.
at first, i thought it was a DNS issue but log shows otherwise.
what else should i look into?

yes, internet is accessible overall; 
browser works normally and from terminal, i have installed packages...
even browsing TuneIn works (which i'm assuming requires online access).

as i stated, the LMS web page shows the rPi player and timer going.

can you suggest a proxy site? and how would i indicate just radio
streams?
can i specify with wildcards, e.g. opml.radiotime/*

Re: [SlimDevices: SqueezeCenter] LMS and TIDAL PLUGIN?

[pavowren]

Tidal plugin works just fine but how about Connect?
Is there a separate plugin or am I missing something?

hi michael, i found HiTide at https://github.com/shawaj/HiTide.
after install, i had to stop squeezelite.service; output device is used
in exclusive mode.
i had it streaming this afternoon but now tidal service is failing to
start.

tomorrow, i will have to either do a clean install or investigate the
error.

yeah, if that's the case, not good.
hopefully that someone actually built it for rpi4, not cut and paste.
in any case, on my setup, it is behaving quite erratically, working, not
working and
working again

tidal connect is reasonably new, so perhaps they will open it up with a
proper sdk.
