Anyone have a manual for do this ?

Regardless of whether your will find tools or perl scripts like h2n, or manage your configuration files directly, you will need to get yourself familiar with basic DNS concepts and terms. A DNS cluster is a number of nameservers that share DNS records. You may perhaps rather want to setup a DNS server system consisting of a master and slave DNS server for your authoritative zone (domain name) on each node, but also configure for DNS forwarding and perhaps caching to public DNS servers on the internet. You may want to configure primary and secondary DNS records on your client sides in /etc/resolve.conf, perhaps also using some round-robin or timeout options.
I'm afraid Google will be your best friend. You may find below links helpful in your approach:

How to install Java on Red Hat

Does anyone know how to install Java on Red Hat. I'm having problems installing it, and I can't really find any instructions anywhere on how to go about it. Thanks.

Java won't run on Red Hat because of firewall
problems.What ? Since when ? But there are problems with certain versions of RH.
Nothing to do with a firewall though.

It only runs on Sun and Windows 95.
But not the Vax version.

How to configure DNS ???

Hi everybody, please tell me how to configure DNS. Which file is needed configuring???
Thanks alot.

Excuse me, maybe u miss understanding about me. I'm not going to keep that information for myself. I don't know that u are interested in it. I always wanna get knowledge from everybody and share my knowledge ,hope that it is useful to someone.
My problem was: i didn't assign defaultgateway to my networking interface (IP 192.168.1.45). I connect internet through a Lan (through another machine IP 192.168.1.12), so if i wanna to use DNS server, i must route my machine to Gateway in order to connect to DNS server.
Thank u for a straight quote. I'm Vietnamese. We are friends !!!

How to Install Oracle on Red Hat Linux?

My System is having P4 1.8 GHz Processor with 128 MB RAM, 40 GB HDD(7 GB Linux Partition + 1 GB Swap Partition). I have installed Red Hat Linux 9(Server). Now, I want to install Oracle 9 on this syste. But I don't know how to install it. Anyone who knows this, plz, mail me the necessary system requirements alongwith some settings, if any. My Email ID is [email protected]/[email protected]

I think you'll have some problems with 128MB RAM.....<br><br>
:P Nonsense, but I do hope that hard drive is one of those new, fancy flash hard drives, otherwise the system will spend so much time swapping that it won't get past the installer.

How to install 11i on Red Hat Linux 64 bit

I'm having problems installing Oracle 11i on Red Hat Linux 64. I understand that it is not supported, however I need to go through the exercise of implementing OATM and then upgrade to 12.
I've started the install and I continue to hit this problem.
Any advise on how to get around this issue. Oracle Support insist on using 32bit. I do have a co-worker that has been able to install it on Red Hat 64bit.

Hi;
I'm having problems installing Oracle 11i on Red Hat Linux 64. I understand that it is not supported, however I need to go through the exercise of implementing OATM and then upgrade to 12. You mean oracle database 11g or you mean oracle e-business suite 11i? I am little confused
If you mention oracle database 11g than check below

How to invoke rman under red hat

hi, friends, i want to use rman for the database in the red hat. however after i typed the command of rman, no responses come out.
what is the reason?
thanks

Take a look at MetaLink <Note:101050.1>.
Under a default REDHAT LINUX 6.1 and 6.2 install, a KDE program called rman (a file
viewing / editing program) is installed under /usr/bin. If this is listed
prior to $ORACLE_HOME/bin in the users PATH environment then it is
called instead of Oracle RMAN.
Ensure that correct RMAN executable is being run by typing
$which rman
The output will most likely show '/usr/bin/rman'
Execute RMAN by typing in the following:
$ORACLE_HOME/bin/rman
Another solution is to add $ORACLE_HOME/bin before /usr/bin
in the PATH environment variable
Hope that helps.

How to configure DNS server to redirect all web traffic to one external website?

I'd like to use the DNS service on my OS X Server as a way to force all all web traffic to one specific, external website. Not quite sure how to go about configuring it, though - any recommendations?
(BTW, this is, obviously, not our primary DNS server; I intend to silently update the preferred DNS server for users who fail to complete their timesheets in order to force the issue)

Web clients don't generate uniquely-identifiable DNS queries; there's no SRV request or related traffic that you could select on and spoof. So if you do implement this, everything querying the spoofing DNS server will get the spoofed host, or you'll have to spot specific queries that are likely web queries; Facebook, Google, Bing, etc.
If you still want to implement this, then I'd probably replace the DNS server with a runt DNS server (maybe hack dnsmasq or maraDNS, or create yourself a trivial DNS server) and have that always return the specified IP address. This avoids having to hack BIND to be universally authoritative, which is probably on par with hacking a simpler DNS server to always return a fixed IP address, and the latter is probably easier to undo.
A firewall can spot TCP port 80 and port 443 traffic, unlike a DNS server. Firewalling outbound port 80 traffic is more typical of these requests, and either trap that traffic to a specific web page based on the capabilities of the firewall, or the web proxy approach that Camelot suggests. There are folks that tie access into the web proxies into external authentication and related; that'd be able to do what you want. Web proxies are usually combined with firewall blocks, as most sites want only the web proxy to have external access, too. But this is also rather more pieces than a DNS redirect, too.

How to configure DNS to support ipv4 and ipv6

I have a 2008 r2 domain controller in my lab.
i'm doing Exchange 2007, 2010 and 2013. I have mix Windows 2008 r2 servers for other applications.
i'm running into issues where i'm thinking it is time to have both IPV4 & IPV6 to run on all lab machines.
I can't get a clear picture on how to accomplish a mix environment. in the DNS administrator do I create a new "reverze lookup zone" with only the IPV6? or do I have to create a new record in the "forward lookup zone" to with both IPV4
& IPV6 which the later points to the new "reverse lookup zone".
I see a lot of internet article but little on "how to".
or on the DC should I enable the DHCP role to support the IPV6?

1. You assign an IPv6 address to the domain controller/DNS server
One method is letting this site (legitimate) create a random private IPv6 range for you:
http://www.simpledns.com/private-ipv6.aspx
For example:
fd06:fcde:8b4e:d6bd:xxxx:xxxx:xxxx:xxxx
You can configure the x's like this (you cannot leave the x's there):
fd06:fcde:8b4e:d6bd:0000:0000:0000:0001
If you close and open IPv6 properties, or do an "ipconfig /all" you'll see that the IPv6 is abbreviated as follows:
fd06:fcde:8b4e:d6bd::1
That's normal.
If you look in your forward lookup zone, you'll now see this IPv6 address (you may have to register that manually - ipconfig /registerdns - but it seemed to happen automatically for me.
So there is no need to create a separate forward lookup zone for IPv6.
OK, but what about the reverse zone?
2. Create reverse lookup
In DNS Manager (what you call administrator), right-click on reverse lookup zone, select New Zone, click, Next, Next (default values are fine) until you choose between IPv6 and IPv4. Selecft IPv6 of course.
Then enter your prefix as shown here:
That's it. The reverse lookup information is configured automatically (your prefix " backwards").
Now, unlike with the forward lookup zone, my domain controller does not seem to be registering its name in the reverse IPv6 zone: there's only the SOA and NS record.
But that's another question.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

HOw to uninstall OBIEE in Red Hat Linux?

Hello All,
How do I completely uninstall OBIEE in Linux (RHEL 5, in my case)?
I tried running setup again, and it did not have any options for removal. The only options were to update the existing installation or to perform a fresh install.
Should I simply remove the OracleBI and OracleBIData directories? Would that be the way to "uninstall" OBIEE in Linux?
Thank you for any help.
-sb

The majority of the programs in Linux can be uninstalled by simply removing the directory where they are installed. OBIEE is not the exception.
