Unable to mount truenas share on Linux VM

TrueNAS General
1

I’m on 25.10.2.1 - Goldeye

I have an SMB share that I can mount without issue on my Windows 11 machine, but I’ve never been able to mount any TrueNAS share on any Linux machine.

I’m guessing its something in the ACL, but I can’t figure it out. I’ve change and tweaked the settings, but to no avail. When I attempt to mount the share I basically get access denied.

For example. When trying to just see what share’s are available from the command line it get:

[root@jughead ~]# smbclient -L truenas
do_connect: Connection to truenas failed (Error NT_STATUS_IO_TIMEOUT)

Also:

Jun 8 10:35:26 jughead kernel: CIFS: Attempting to mount //truenas/test
Jun 8 10:35:36 jughead kernel: CIFS: VFS: Error connecting to socket. Aborting operation.
Jun 8 10:35:36 jughead kernel: CIFS: VFS: cifs_mount failed w/return code = -115

Nothing is blocking the request.

Port 445 is open:

Starting Nmap 7.92 ( https://nmap.org ) at 2026-06-08 10:22
Nmap scan report for truenas (192.168.0.109)

I can mount other share’s on other NAS’s that I own. I feel this is something with either TrueNAS or the ACL permissions.

I’m using Rocky Linux 8.10,

Is the vm on run on truenas or another hypervisor?
If it’s run on truenas did you set up a network bridge? Otherwise the vm is isolted from the host bye default.

This is a truenas vm.

Set up a network bridge. Interesting. Is there documentation for this somewhere?

Thanks
