samba - Aug 2017 - configuring samba for virtualbox guest os host only network

Dear samba users:

I am new on this list and know samba at a very basic level.
I use openSUSE 42.2 Leap with its default samba 4.4.2 version.

This is what I would like to achieve:

I have a guest windows OS in virtualbox 5.1. Occasionally
I have to print documents from this guest OS using my printer
configured in openSUSE. I would like to use samba to share my
printer between the linux host and the guest OS. Virtualbox
uses a network host-only network adapter called vboxnet0.
Unfortunately this adapter only becomes available when
virtualbox program is started. My problem is how to start samba.
If I don't add my eth* network card to smb.conf nmb cannot start:

linux:~ # systemctl restart nmb
Job for nmb.service failed because a timeout was exceeded. See 
"systemctl status nmb.service" and "journalctl -xe" for
details.
linux:~ # systemctl status nmb.service

I don't want samba to use my eth* network.

This is my current smb.conf file:

[global]
     add machine script = /usr/sbin/useradd  -c Machine -d 
/var/lib/nobody -s /bin/false %m$
     domain logons = No
     domain master = No
     local master = Yes
     os level = 65
     preferred master = Yes
     security = user
     wins support = No
     workgroup = SAMBA
     bind interfaces only = No
     interfaces = vboxnet0
     netbios name = LINUX
     passdb backend = smbpasswd
     usershare allow guests = No
     ldap suffix      wins server 
[printer]
     comment = laser-printer
     guest ok = Yes
     path = /var/tmp
     printable = Yes

This worked in openSUSE 12.2 with samba 3.x.

What would be the way to configure samba in this case?

Thanks,

Istvan

Hi,

I would stop forcing Samba to listen on non-existing interface. Doing that
it should listen on every existing interface and if you are lucky, it
should listen on VirtualBox generated interface when it becomes available.

Another way to achieve that, this time keeping "interfaces = vboxnet0"
in
smb.conf, would be to start VirtualBox at startup, doing that the interface
should become available at start up, then you just have to manage that
Samba starts after VirtualBox.

Please come back to tell us how things went.
