I see a lot of discussions going on in other forums wherein we discuss about domains. I searched google and all I could understand by looking at various results is that domain is some sort of methods using which some PCs can be grouped. Is is something like creating a subnet or more like a service for a network? and what are the differences between a LAN and a Domain?
EDIT: I know about the Domain names but what is the 'domain' in a private network ... like a LAN?
A domain is merely a unique name that an IP address resolves to. Domain names are for humans. A server is found by its IP address.
A "DNS" matches the domain name to its corresponding IP address and sends the request to the server.
A Domain is a group of computers that are managed by a central server. "Domain" was coined by Microsoft, but there are other names for the same configuration for other operating systems.
The Domain is given a unique name, that as JPnyc mentioned, i used by humans. You see these unique domain names everyday on the internet; www.google.com, any website and @mycompany.org, on any email address.
[edit]
To answer that, imagine a company with employees that each use a computer. Those computers are then managed by a central server, called the domain controller, each workstation the employees use is a domain member.Quote:

The domain controller is in charge of things like user accounts and passwords, restricting use and applying individual configuration settings for each user and or computer itself. Anyway, the list goes on and on..... really!

I suppose in a loose sort of way you could think of the LAN as the physical entity (the actual computers) and the backbone (routers, switches etc.) of the whole thing - and think of the domain as a software administrative aid to manage the computers (hosts) and the security of them from an Operating System point of view.Quote:
what are the differences between a LAN and a Domain?
Everything in the same domain shares an element of trust with each other and all do what the domain controller(s) says. One person can manage an unlimited number of hosts and is called the domain administrator. As everything in the same domain will implicitly trust the domain admin this makes management tasks extremely easy. Likewise anything not a member of the domain is not trusted b default unless configured otherwise - making securing the domain from external person(s) easier then it may otherwise be.
A workgroup is similar to a domain except there is no controller available and everything is configured individually on each host. - usually this is the method when there are only a few hosts (say 10 or less) or there are no services which require a domain to be in place.
To add to Nokia's differences, you can have multiple domains available on the same physical LAN. You can also set up "trusts" between domains on a LAN so that they can share resources.
Well, Now the things are quite clearer than before. I thought that 'domains' were related to Linux also. Anyway.... thanks a lot.
SO I think that the 'Active Directory' services are deployed for the management and configuration of the domains? And the active directory is nothing but the container type object with the elements being the resources for the management of the 'domain'?
Anyway what is the 'Linux equivalent' of the 'Windows Server Domain'?
Kind of, there is much more to that capabilities and usage Active Directory than that but in essence I suppose you are correct.Quote:

Crap! :DQuote:

So do I assume that there is nothing in Linux to manage the networks just like Windows? Then how do those big sites and so many companies run Linux in their production centers??
There are similar applications out there but they're not exactly the same (to my knowledge ayway). There are 100's of plugin's for Active Directory to make it compatible with *nix based hosts for certain services and certain functions - and there are things like OPenLDAP etc that will handle the authentication side of things for *nix hosts - but for domain managment, administration and security nothing comes remotley close to Active Directory.
Thanks for throwing away light on the topic.
You told about Windows - *nix network management. Thats good. However one question that still survives is that "what if all the computers on the network are running *nix (Assume LINUX)"? How do they manage their network then?
Hi,
Yesterday, one of my friends, expecting an answer back, asked me if I know how to setup an Exchange server for SMTP, DNS and POP on Windows 2003 server OS. Of course my reply was negative but the question sounds interesting. I am not asking it as a "ask-and-do and earn the credit yourself question" but I want to know how to do it.
I know that many of the AO members have done this thing. So I expect at least a couple of replies back from your side.
This is something I got yesterday while posting a new thread. Its not working till now. Is everything working right (System admins might check this!):

I don't think you will get much help with such an obscure question as that. If you ran into specific problems and asked about thse, then it will be easier to help you out....
Nokia is right...although I believe MS based thier AD on Novell Server and the Groupwise network management.Quote:

I havent used Novell for 10 years or so...so I am unsure of it functionality now.
From what I can remember..MS Domains where much easier to set up...specially the printing ;)

Novell isnt dead yet? lol.

I good overview of eDirectory is here
This links to a good overview of Directory Services as a concept with links to various offerings available.
Read up, and come back with any questions if you have trouble with some of the concepts.
Thats right
AD is MSes version of NDS...I said groupwise...which is the exchange like app
:confused:
see what happens when you dont use it.....you lose it ;)

I still remember setting up Novell on Windows 95 and thinking it was the greatest thing in the world. Times have changed.
The first Novell server I set up...I used floppies, on a 286.
One thing about a Novell server........rarely required a restart...those things just sat in the corner and hummed along for years
Geez........I feel old :(
MLF
Morgana~ you probably won't believe this but I was rummaging around the other day and actually found a set of those floppies............ and Norton 1.0.......... finds all 720 viruses in the known Universe........... :eek:Quote:

:D
Old? I think you have a bit of catching up to do young lady!
720 known viruses.........:LOL:
young lady........flattery will get you everywhere ;)
MLF
Im pretty sure clamav scans for over 94,000 known viruses now haha. That doesnt include heuristics...
oofki old chap................ keep your software up to date!
132,493 as of about 5 minutes ago :D
I would imagine this to be a natural progression regardless of who came up with the concept. Having a database that controls security/permissions across an entire network...... I dont think M$ has to steal that idea! :pQuote:
