[Samba] Problem with DNS configuration and "host" command . . .
I'm following the instructions here --
https://wiki.samba.org/index.php/Setup_a_Samba_Active_Directory_Domain_Controller
I've successfully "tested" my domain controller --
adam at eagle:~$ smbclient -L localhost -U%
Domain=[SMBDOMAIN] OS=[Unix] Server=[Samba 4.1.18-Debian]
Sharename Type Comment
--------- ---- -------
netlogon Disk
sysvol Disk

adam at eagle:~$
adam at eagle:~$ smbclient //localhost/netlogon -UAdministrator -c 'ls'
Enter Administrator's password:

49698 blocks of size 2097152. 46051 blocks available
adam at eagle:~$
*It's when I get to the "host" command that it fails* --
adam at eagle:~$ host -t SRV _ldap._tcp.eagle.smbdomain.com.
Host _ldap._tcp.eagle.smbdomain.com. not found: 3(NXDOMAIN)
adam at eagle:~$
Ubuntu "suggests" configuring a static ip in
'/etc/network/interfaces'
(instead of 'resolv.conf') --
adam at eagle:~$ cat /etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.121.149
netmask 255.255.255.0
gateway 192.168.121.1
dns-search smbdomain.com
dns-nameservers 192.168.121.149
adam at eagle:~$
Here's my 'smb.conf' (as provisioned, no edits) --
adam at eagle:~$ cat /etc/samba/smb.conf
# Global parameters
[global]
workgroup = SMBDOMAIN
realm = SMBDOMAIN.COM
netbios name = EAGLE
server role = active directory domain controller
dns forwarder = 192.168.121.1
idmap_ldb:use rfc2307 = yes
[netlogon]
path = /var/lib/samba/sysvol/smbdomain.com/scripts
read only = No
[sysvol]
path = /var/lib/samba/sysvol
read only = No
adam at eagle:~$
Any suggestions? Thanks.

Set /etc/resolv.conf to point to itself: search smbdomain.com nameserver 127.0.0.1 # or you could use the DCs IP> > adam at eagle:~$ cat /etc/network/interfaces > > # The loopback network interface > auto lo > iface lo inet loopback > > # The primary network interface > auto eth0 > iface eth0 inet static > address 192.168.121.149 > netmask 255.255.255.0 > gateway 192.168.121.1 > dns-search smbdomain.com > dns-nameservers 192.168.121.149Remove the 'dns' lines they do not really belong in this file. See if this fixes your problem, if not report back.

I misunderstood the command -- adam at eagle:~$ host -t SRV _ldap._tcp.smbdomain.com. _ldap._tcp.smbdomain.com has SRV record 0 100 389 eagle.smbdomain.com. adam at eagle:~$ I arrived at the conclusion by following the instructions here -- https://wiki.samba.org/index.php/Testing_DNS_Name_Resolution thx

Thanks for the suggestions. You know how it is. You work on a problem for awhile, and then you put it into words, and all of a sudden, the answer comes to you from some other source (as here)> >> adam at eagle:~$ >> >> Here's my 'smb.conf' (as provisioned, no edits) -- >> >> adam at eagle:~$ cat /etc/samba/smb.conf >> # Global parameters >> [global] >> workgroup = SMBDOMAIN >> realm = SMBDOMAIN.COM >> netbios name = EAGLE >> server role = active directory domain controller >> dns forwarder = 192.168.121.1 >> idmap_ldb:use rfc2307 = yes >> >> [netlogon] >> path = /var/lib/samba/sysvol/smbdomain.com/scripts >> read only = No >> >> [sysvol] >> path = /var/lib/samba/sysvol >> read only = No >> adam at eagle:~$ >> >> Any suggestions?
