Just like @aidyw I have a Duet receiver that has done sterling service for years, but the controller died some time ago, and the Duet's been getting flakey on my network. UDAP looked like the tool to attempt a rescue.

My attempts to run the precompiled/packaged copy of UDAP 1.0.0 on Windows failed. The tool was emitting a slew of warnings about missing modules and suchlike so I didn't have much hope.

However, I got an installation on Linux (Debian Buster/Sid) running, once I had sorted out all the missing CPAN dependencies.

Current State

The tool runs without error, finds the Duet (temporarily on a wired ethernet i/f), and reads the settings, which do look a bit hinky. They show a mixture of my old Squeezecenter server address (192.168.0.41), and the current one (192.168.0.40). There's also a lan network address and subnet mask that I don't recognise, but these are maybe factory defaults as the device was always used wirelessly up until now.

Symptoms

I tried to change the settings to try to move the Duet temporarily onto the hard wired interface, just to prove it's working-

UDAP [1] (squeezebox 172dd2)> set lan_network_address=192.168.0.51 lan_subnet_mask=255.255.255.0 squeezecenter_address=192.168.0.40 squeezecenter_name=Holly interface=1

But when I write this to the client and reset it. nothing changes ?! I have to put the Duet back into "init" mode for UDAP to find it (by holding the front panel button until it slow-blinks red), and when I d so and list the settings they are all exactly as they started, nothing has changed.

I've tried power cycling the Duet after writing the settings, but nothing seems to "stick".

Any idea what is happening here? I'm running UDAP as a normal user rather than root, which is generally safer, and there are no access errors showing up. Does UDAP need to run as root to write to the device?

using github master branch I get error ;

./scripts/udap_shell.pl

referring to the original wiki page, the branches is 1.0.x.
github import is not the same ?

with svn 1.0.x I get a discover error

Hi,
I have resurrected an old squeezebox receiver and the controller for it is dead. So I was very glad to find your code to perhaps help me overcome this problem. However I am struggling to overcome compile issue. I have tried a few times as initially I was hitting problems with package dependencies. Having tried resolve these.
I'm using Ubuntu 18.04LTS.

Specifically I ended up copying:

/usr/share/squeezeboxserver/CPAN/HTTP/Net/UDAP/Message.pm
into
./lib/Net/UDAP/Message.pm

i.e. into the local git repo I cloned from this project. I overcame the first dependency problem, but now when I run make test I encounter this:

make test
PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/.t
t/00.load.t ....... 1/5 # Testing Net::UDAP v1.0_01

Now I have to say, this looks like it might too be related to a dependency on a particular file, but I am not useful in any way with perl. Googling this for a day or so has lead me down a perl hellhole.

Please could you suggest what might be the issue and is it not possible to simply include all the specific dependencies for this module into the project on git? Surely this would avoid me having to patch it all together with no knowledge of how or what CPAN is doing or how perl environments works.

Still I sure would like to bring my squeeze receiver back to this world.
Thanks in advance.
