SMB bind network interface

[crazystar]

Hello all,

 

I have 4 network interfaces out of which 1 interface is in Management VLAN and the other three are bonded via LACP. I would like to bind the samba service to the bonded interface. I added the following to the SMB extra conf page but doesn't seem to be working.

 

bind interfaces only = yes
interfaces = lo br1

Tried bond1 and br1, both did not work. Any advice?

 

Thanks

No. Apparently you can’t change from the default interface.

What makes you say this?

I tried and couldn’t get it work. SMB for whatever reason was always bound to the main Interface and I couldn’t get it to use the LAGG interface.

How many IP addresses are assigned to Unraid, and what do you get when you run

# netstat -lntp | grep smbd

You should get kinda like

tcp        0      0 127.0.0.1:139           0.0.0.0:*               LISTEN      30554/smbd
tcp        0      0 192.168.2.5:139         0.0.0.0:*               LISTEN      30554/smbd
tcp        0      0 127.0.0.1:445           0.0.0.0:*               LISTEN      30554/smbd
tcp        0      0 192.168.2.5:445         0.0.0.0:*               LISTEN      30554/smbd

which should only list your IPs to the bound interfaces.

 

In my case I have two interfaces and smbd is only bound to br0 and lo; but then again I only one IP assigned to Unraid, so the other VLANs need to use the router to reach Unraid, even it was a local container or VM (unless the VM is Linux and I'm using Plan9 mounting)

tcp        0      0 0.0.0.0:139             0.0.0.0:*               LISTEN      10359/smbd          
tcp6       0      0 :::445                  :::*                    LISTEN      10359/smbd          
tcp6       0      0 :::139                  :::*                    LISTEN      10359/smbd  

 

Thats what I get. Strange thing is that none of my actual ip's show up. I have 3 nics that are attached to my machine. 1x pcie 10g and 2 onboard gbit. I have my 10g set as eth0, one of the other gbit set as eth1 and the eth2 is set as port down. 10g nic 10.10.20.0/24 and 1g nic 10.10.0.0/24. I have docker services running on both devices and can confirm that data is flowing on the respected nic.

 

Below is my samba settings

ntlm auth = yes

#unassigned_devices_start
#Unassigned devices share includes
   include = /tmp/unassigned.devices/smb-settings.conf
#unassigned_devices_end

#use samba on 10g network only
bind interfaces only = yes
interfaces = lo eth0

however when I look at the dashboard at the network activity and start a large file transfer I do not see it going through my 10g but the 1g nic. I have tried switching eth0 and eth1 and the traffic follows the 1g nic.

it's working on my configuration by adding the tag [global] in smb.settings so your lines should be :

 

#use samba on 10g network only

[global]

bind interfaces only = yes

interfaces = lo eth0
