Public bug reported:
I am running an almost-newly-installed Ubuntu Server 12.04 beta 2.
Here's the output of ifconfig -a:
leo@blackbox:~$ ifconfig -a

During installation, the following manual IP settings - address 10.37.55.20,
netmask 255.255.255.0, gateway 10.37.55.1, nameserver 10.37.55.20 - were given,
and the package tasks "DNS server" and "Virtual Machine host" were selected (as
well as "OpenSSH server"). It all seems to be working, though I haven't tested
the virbr0 VM interface.
I have used <a
href="https://bugs.launchpad.net/ubuntu/+source/samba4/+bug/832465/comments/7";>Roger
Hunwicks' workaround</a> to work around <a
href="https://bugs.launchpad.net/ubuntu/+source/samba4/+bug/832465";>bug
832465</a>, so samba4 now installs without aptitude reporting an error.
Whenever /usr/share/samba/setup/provision is run without using the
option --host-ip , provision apparently chooses virbr0's IP address
(192.168.122.1) and not that of eth0 (10.37.55.20):
leo@blackbox:~$ sudo /usr/share/samba/setup/provision
--realm=irishtown.localonly.rvcomerford.ie --domain=IRISHTOWN --adminpass=[a
password] --server-role=dc

Fixing provision GUIDs
A Kerberos configuration suitable for Samba 4 has been generated at
/var/lib/samba/private/krb5.conf
A phpLDAPadmin configuration file suitable for administering the Samba 4 LDAP
server has been created in /var/lib/samba/private/phpldapadmin-config.php .
Once the above files are installed, your Samba4 server will be ready to use
Server Role: domain controller
Hostname: blackbox
NetBIOS Domain: IRISHTOWN
DNS Domain: irishtown.localonly.rvcomerford.ie
DOMAIN SID: S-1-5-21-1208001617-3832972804-1616836880
This includes when provision is (apparently) run during package
installation.
I assume this might leave samba wrongly configured to serve eth0 and the
10.37.55.0/24 subnet. But I'm not actually sure, partly because there's
no actual mention of IP addresses in the generated /etc/samba/smb.conf ,
whether or not provision is called with --host-ip . When provision is
given --host-ip=10.37.55.20 , the resulting /etc/samba/smb.conf is
# Global parameters
[global]
server role = domain controller
workgroup = IRISHTOWN
realm = irishtown.localonly.rvcomerford.ie
netbios name = BLACKBOX
passdb backend = samba4
[netlogon]
path = /var/lib/samba/sysvol/irishtown.localonly.rvcomerford.ie/scripts
read only = No
[sysvol]
path = /var/lib/samba/sysvol
read only = No
, which seems identical to the result when --host-ip is not specified.
The lines
Looking up IPv4 addresses
More than one IPv4 address found. Using 192.168.122.1
no longer appear in provision's standard output, though.
So it seems that either samba4 is being set up incorrectly, or provision
- and so also samba4 package install - is misleadingly suggesting that
samba4 is being set up incorrectly.
My version of samba4 is 4.0.0~alpha18.dfsg1-4 . However, I've also seen
the same behaviour when trying to set up samba4 from the official
alpha18 tarball on both 12.04 beta 2 and 11.10, and when trying to set
up samba4 using 12.04 beta 2 and packages from the <a
href="https://launchpad.net/~samba-team/+archive/daily";>official Samba
daily builds PPA</a> on 5 April 2012.
