I am doing some testing for DNS
I got a master DNS(192.168.2.10) and I setup a slave DNS(192.168.2.11) but when I shutdown the Master DNS my linux client cannot resolve using the slave
any idea way?
This is the named.conf
training.com.db
$TTL 86400
@ IN SOA masterdns.training.com root.training.com. (
2009111914 ; Serial number needs to be increase when zone changes

Code:

type slave;
notify yes;
allow-query { any; };
file "data/sec.2.168.192.zone.db";
masters { 192.168.2.10; };

I only have a few groups, so it's not the problem everyone else had. When I've mounted a disk over NFS, I need to have my primary group in order to read in the groups I'm a member of. Secondary groups is not working.

findsmb
FINDSMB(1)FINDSMB(1)NAME
findsmb - list info about machines that respond to SMB name queries on a subnet
SYNOPSIS
findsmb [subnetbroadcastaddress]
DESCRIPTION
This perl script is part of the samba(7) suite.
findsmb is a perl script that prints out several pieces of information about machines on a subnet that respond to SMB name query requests.
It uses nmblookup(1) and smbclient(1) to obtain this information.
OPTIONS -r
Controls whether findsmb takes bugs in Windows95 into account when trying to find a Netbios name registered of the remote machine. This
option is disabled by default because it is specific to Windows 95 and Windows 95 machines only. If set, nmblookup(1) will be called
with -B option.
subnet broadcast address
Without this option, findsmb will probe the subnet of the machine where findsmb(1) is run. This value is passed to nmblookup(1) as part
of the -B option.
EXAMPLES
The output of findsmb lists the following information for all machines that respond to the initial nmblookup for any name: IP address, Net-
BIOS name, Workgroup name, operating system, and SMB server version.
There will be a '+' in front of the workgroup name for machines that are local master browsers for that workgroup. There will be an '*' in
front of the workgroup name for machines that are the domain master browser for that workgroup. Machines that are running Windows for Work-
groups, Windows 95 or Windows 98 will not show any information about the operating system or server version.
The command with -r option must be run on a system without nmbd(8) running. If nmbd is running on the system, you will only get the IP
address and the DNS name of the machine. To get proper responses from Windows 95 and Windows 98 machines, the command must be run as root
and with -r option on a machine without nmbd running.
For example, running findsmb without -r option set would yield output similar to the following
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION

This man page is correct for version 3.0 of the Samba suite.

The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
The original Samba man pages were written by Karl Auer. The man page sources were converted to YODL format (another excellent piece of Open
Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba 2.0 release by Jeremy Allison. The conversion to
DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
