Hello,
I've created new DNS servers and changed all of the clients /etc/resolv.conf to point to them, but when I check the old DNS logs, I see that the clients are still querying it. Does anybody know why?

Hello,
I'm using CentOS 5.3, and I connect to a VPN in order to work. The problem is that I'm constantly accessing things on the local network and the remote network. But once I'm connected to the VPN I can't access local addresses by name, I have to use the ip-address.

I am trying to setup a CentOS 6.2 server that will be doing 3 things DHCP, DNS & Samba for a very small office (2 users). The idea being this will replace a very old Win2k server. The users are all windows based clients so only the server will be Linux based.

I have read many tutorials on bind and i understand the A,MX, CNAME records.
Internally, on a LAN we can install bind and create all these records and we can tell all PC and servers to use this bind as DNS server.that's fine.

getopt
getopt(1) General Commands Manual getopt(1)Name
getopt - parse command options
Syntax
set - - getopt optstring $*
Description
The command breaks up options in command lines for easy parsing by Shell procedures and checks for legal options. The optstring option
letters are recognized if a letter is followed by a colon, the option expects an argument which may or may not be separated from it by
white space. For further information, see
The special option, specified by two minus signs (- -), delimits the end of the options. If the delimiters are used explicitly, recognizes
it; otherwise, generates it. In either case, places the delimiter at the end of the options. The positional parameters ($1 $2 ...) of the
shell are reset so that each option is preceded by a single minus sign (-) and is in its own positional parameter; each option argument is
also parsed into its own positional parameter.
Examples
The following code fragment shows how you can process the arguments for a command that can take the options a or b, as well as the option
o, which requires an argument:
#!/bin/sh5
set -- getopt abo: $*
if [ $? != 0 ]
then
echo $USAGE
exit 2
fi
for i in $*
do
case $i in
-a | -b) FLAG=$i; shift;;
-o) OARG=$2; shift 2;;
--) shift; break;;
esac
done
This code accepts any of the following as equivalent:
cmd -aoarg file file
cmd -a -o arg file file
cmd -oarg -a file file
cmd -a -oarg -- file file
Diagnostics
The command prints an error message on the standard error when it encounters an option letter not included in optstring.
