Unable to connect to shared drive on CX with AMS 4.1 from any version of MacOS

soundserge · May 12, 2023, 11:23am

For the last couple of weeks I have been unable to connect to the shared (SMB) drive on my CX running AMS 4.1. (I’ve been unable to upgrade to the latest release of AMS, but that’s for another topic)

From three different Macs —2 running MacOS Ventura 13.3.1 and 1 running Big Sur 11.7.6— I am unable to connect to the shared folder /storage/music/flac, whether from Finder or from the command line. I can ping the CX both by IP and hostname as well as nc (netcat) the relevant SMB ports (139 and 445). I’ve tried everything both wired and wireless.

These same Macs are able to connect to other SMB shares I have on the same subnet on a QNAP NAS. I am also able to connect to the Antipodes CX shared folder from a virtual machine running Linux on one of these Macs. And, I can mount the share and browse my music on the CX using the FileBrowserGo iPad app.

Roon Server functions just fine on the CX, streaming to a Meridian endpoint over ethernet. So I know that the CX works and -some- devices are able to access the shared music folder. Just not any of the devices running MacOS. This is preventing me from adding music to my Roon library.

I am aware of the history around poor SMB (client and server) implementation on MacOS, but this used to work just fine and it doesn’t anymore. I’ve tried a range of diagnostics: tcpdump, wireshark, nmap, etc. All signs point to the SMB server on the CX closing the connection during a negotiation stage.

Has anyone else experienced anything similar? Otherwise, the next step is to book a remote session so that we can take a look at what the SMB server side is doing…

SMB to my K-series server has been rock solid from my Macs. I have been uploading music daily for a few years and have never had an issue.

This sounds like a network issue. I would start with rebooting every device between your Mac and the CX. Reboot the CX as well.

Name resolution can be flaky in a mixed environment. From Macs, you have the option to connect to a share using the IP address. Go to Finder and select Connect to Server under the Go menu. Type in the following (but substitute the IP address for your CX):

smb://10.0.0.26/storage

Thanks. Mounting antipodes SMB share had been rock solid for me as well, until about two weeks ago. I’ve already rebooted every device in the chain several times. I’ve also tried using both IP address and hostname.

When I trace the communication between my Mac and the CX (either via increased logging level in the MacOS system log, via packet sniffing, or with nmap, it’s clear that the Mac and the CX are talking the SMB protocol. They find each other just fine. At some point the SMB server just closes the connection for reasons unclear.

I assume the software on your CX has remained static since the last upgrade you applied. (This is a nice benefit of infrequent updates). Try a process of elimination to see if something else in the chain is to blame.

Thanks for thinking along with me. Based on the facts I’ve gathered, the root cause is something specific to the combination of MacOS and the SMB implementation in AMS.

Again, the same Mac will mount all SMB shares on the same subnet as long as they aren’t on the CX. The same Mac will even mount the CX’s SMB share, but only from within a VM running Linux.

The issue started at some point while running AMS 3.x. Meaning, it worked with 3.x for months, and then it just stopped. I had hoped that upgrading to 4.x would fix something, but it didn’t.

If that’s true, why is it only impacting your Mac?

soundserge · May 13, 2023, 9:42am

This is the $64 mln question

soundserge · May 13, 2023, 9:48am

And, mind you, it’s not just -a- Mac, it’s all three Macs.

kennyb123 · May 13, 2023, 5:09pm

Which all share your same network. I’m unaware of any reports outside your home of Macs that are having this same issue. For that reason, I just don’t see how you could arrive at the conclusion that “the root cause is something specific to the combination of MacOS and the SMB implementation in AMS”. I could be wrong of course. I only mention this to encourage you to continue the search for the root cause. Simplify your network chain such that there is a simple path. Also make sure you are connecting to AMS as the guest user. Delete any keychain credentials that might have been saved. Make sure your router isn’t blocking multicast or that you don’t have a VPN that’s mucking with things.

You are right, I left off the qualifier “on my network.” Also, you are of course correct to point out that proper debugging technique dictates that I eliminate as many connections and variables as possible. For the sake of science, I just connected my MacBook to the same switch as the CX, and turned off the WiFi. The symptoms are exactly the same.

I am connecting as the guest user. There are no keychain entries for the CX hostname or its IP address. Multicast is not blocked on my router nor switch as this facilitates discovery of the Roon core. There is no VPN involved.

Here’s what I’m seeing:

From the command line:

MacOS $ mount -t smbfs //guest:@antipodescx/storage/music/flac /Users/<redacted>/roon
mount_smbfs: server connection failed: Socket is not connected
mount: /Users/<redacted>/roon failed with 68
MacOS $

MacOS log for the above command:

To add insult to injury, I installed the OwlFiles file browsing app from the MacOS App Store on the same MacBook. It is able to mount and browse the CX via SMB just fine:

It doesn’t appear to be using the native SMB client though, because I don’t see anything in the system log.

kennyb123 · May 16, 2023, 3:42pm

I think your best bet is to set up a 1-on-1 session with Antipodes and have them do a reinstall of AMS. It does look like the problem is with your CX so maybe something went amiss when AMS was upgraded.

soundserge · June 8, 2023, 5:13pm

Update: during a 1-on-1 session last night, my CX was upgraded to AMS 4.31. Unfortunately, the problem persists. A senior engineer is supposed to follow up.

soundserge · February 9, 2024, 5:27pm

Update; Upgraded to AMSv5 this week and the issues described above have been resolved. In the end it was MacOS insisting on a minimum version of SMB (for security reasons) that AMSv4 didn’t support.
