Introduction
Samba enables you to change switch between the INTERNAL_DNS
and BIND9_DLZ
DNS back end on your Active Directory (AD) domain controller (DC) without loosing data.
Changing From the Samba Internal DNS Server to the BIND9_DLZ Back End
Run on your domain controller (DC):
- Set up and configure the
BIND9_DLZ
back end. For details, see BIND9_DLZ Back End.
- Shut down the Samba service.
- Migrate the back end:
# samba_upgradedns --dns-backend=BIND9_DLZ
- Use one of the following ways to disable the internal DNS in your
smb.conf
file:
- If you have a
server services
parameter, remove thedns
option. For example:
- If you have a
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate
- If you do not have a
server services
parameter, add the following line:
- If you do not have a
server services = -dns
- Enable the BIND service to start at boot time. See your distribution's documentation for details.
- Start the BIND service.
- Start the Samba service.
Changing From the BIND9_DLZ Back End to the Samba Internal DNS Server
Run on your domain controller (DC):
- Shut down the BIND service.
- Disable the automatic start of the BIND service at boot time. See your distribution's documentation for details.
- Shut down the Samba service.
- Migrate the back end:
# samba_upgradedns --dns-backend=SAMBA_INTERNAL
- Use one of the following ways to disable the
BIND9_DLZ
module in yoursmb.conf
file::
- If you have a
server services
parameter, add thedns
option. For example:
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate, dns
- If you only have the
-dns
option listed in theserver services
parameter, remove the entire parameter:
server services = -dns
- Start the Samba service.
The internal DNS is one of the default settings of the server services parameter. Removing the server services parameter enables all the default servers including the DNS server. |
