11.2 - BETA3: SAMBA broken

[creativecave]

Hi, since i updated from 11.1-U6 to 11.2-BETA3 samba doesn't work anymore.
I have 3 Macs here and they all connect perfectly using AFP but SMB is not working.

I have tried to create new datasets and new shares, nothing helps.
SMB service is running!

Can someone help me to identify the problem?
Or point me to the right log file?

Thanks
Eugen

I think, this could be the reason:

Not broken here, at least not when connecting to SMB share from a linux client. 11.2-BETA3 uses an updated SAMBA package, see: https://redmine.ixsystems.com/issues/41380

But where are you seeing this error message?

For you reference:

On FreeNAS basic SAMBA checking at the CLI as root includes:

1. Checking SMB service status and any client connections with smbstaus

2. Checking SMB share names with smbclient -L locahost , just press enter when asked for a password

3. Via the webUI increase SMB service logging level to say "normal" at first. Beware, higher log levels can generate a lot of output.

4. Viewing logs at: /var/log/samba4/log.nmbd and /var/log/samba4/log.smbd

5. Checking SMB server config global section from the output of command testparm or testparm -v

One obvious change I can see is the "server min protocol" is set to SMB2 in 11.1-U6 and has a value of SMB2_02 in 11.2-BETA3. But I've no idea if this is your problem.

Thank you! I will test everything an report back.

I got this message from this little window at the bottom of the Web-UI.

Pease check output.txt for the output of the suggested commands.


Thank you

In your case, as you are getting a winbindd errors it's also worth checking /var/log/samba4/log.winbindd and /var/log/messages

You also need to post the mount command you are using on your MAC client and any error message you see on client when trying to connect to your smb share. When you try to mount your share on the client, at the same time inspect the smbd log on FreeNAS, just use tail -f /var/lo/gsamba4/log.smbd to do that. Make sure you have the syslog written to your pool ( via System > System Dataset )

The command smbclient L -localhost on FreeNAS didn't seem to return anything, which is odd. As this is a MAC problem I'm can't be of more help. If it's not a mis-configuration of server or client and as things were working under 11.1.-U6 it could be a bug due to the samba update in 11.2-Beta3.

Try contacting @anodos whose is a iXsystem SMB expert and posts on this forum.

Let's try clearing the winbind cache:

Code:

service samba_server stop
rm /var/db/samba4/winbindd_cache*
net cache flush
service samba_server start

 

[creativecave]

I already cleared the cache. Here is the output from log.winbindd:

this is the mount command:

Password for freenas.local:

mount_smbfs: mount error: /Volumes/eugen2: Operation not permitted


Usually i mount the shares with "Finder" and it always worked before this update.


Thanks you for helping...

Can you download the winbind core file from /var/db/system/cores, zip it up, and PM it to me?

Also generate a pcap on the FreeNAS server of the failed mount attempt from OS-X.
tcpdump -i <interface> -p -s0 -w /tmp/smb.pcap host <ip of mac>

i.e. "tcpdump -i em0 -p -s0 -w /tmp/smb.pcap host 192.168.42.42"

Hit control-c when the connection fails and download / zip up and PM the resulting file.
