Server :: W2k Pdc To Centos Migration
Feb 14, 2011
I have a Windows 2k server running the AD PDC. 60 desktops users and 6 Windows servers use it as a single sign on server to login. As I plan to install a Centos 5.5 server with Samba for NAS and print sharing, is it possible to migrate the PDC services to the Linux server? I want desktop users and windows servers to authenticate on the Linux server. Is this possible? I have never worked with LDAP services. Worse, should I attempt this migration, it must be completed in a very short time frame.

I have a lightweight admin background, but good enough to set up most servers. I have switched from sendmail to postfix for the first time, but I keep going around in circles on the following...
In sendmail, I used to maintain a table (mailertable) where I would redirect email like this

Im a fairly new linux person and have a hopefully easy question. I am running centos with dovecot and postfix for the mail. Im using imap so all the mail is on the server. Im also using thawte certificates. What is the easiest way to move all of this over to a more stable box? The box i have now is a major POS.

I'm migrating a mailserver from an old to a new mailserver. The new mailserver is based on ISPConfig 3.0.6.1. I would like to migrate what spamassassin learnt in the past from the old mailserver to the new one. Now the question:
- The 2 spamassassin versions are different. Is it a problem?
- Can I just migrate the database with this commands???
Code:
sa-learn --backup > sadb.bkp
sa-learn --restore ./sadb.bkp
-how to migrate SpamAssasins Auto White List and all others SpamAssassins databases?

I happily mapped any incoming email address of any valid hosted domain either to go out to it's final destination via smtp, or if the person has a local mailbox, it delivered locally. Any errors could be forced, and a catch-all for the domain could be directed also.
I've struggled with virtual hosts and transport and a combination of the two to come up with the same result for postfix. I have this feeling I'm missing something really simple, or I am not 'getting it' when I'm doing something postfixy and I still have sendmaily expectations. right path so I will at least know I'm pointing in the right direction and working with the right files to achieve my aims? Postfix is so amazingly powerful and flexible, I'm having trouble figuring this bit out.
I have this feeling I just need a calm hand on my shoulder, a friendly smile and a hand pointing me the right way..

I am not new to linux but switching to ubuntu for the first time. I had WAMP server installed in my desktop. I made a small website using php and saved all its contents in the WWW folder within the WAMP folder present in the C: drive, (where windows is installed). Now I have installed Ubuntu. I want to know that how could I make that website work in ubuntu also. Or you can say that I would like to know that WHERE would I paste my website source code files in Ubuntu so that I dont have to work again from scratch and make the website run easily in Ubuntu.

I have a RAID5 with 5x2TB HD's and I'm planning a major hardware overhaul. My server currently runs on a Pentium4 3.2 Ghz (pre multicore technology) on a SuperMicro mobo. I'm planning to switch to an AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz, 3.7GHz Turbo 6.
So here's the question. Can I just plug my drives to the new board and restart the RAID like nothing happened? I don't have space to backup all my data if I have to recreate the RAID from scratch. Intel and AMD should be binary compatible (I mean the RPM's work) so I should be able to invoke mdadm to assemble the RAID after I install Linux on the new server. Right?

I'm looking into migrating postfix mailboxes and users from an old machine running Fedora5 to a new machine running cenOS. I was wondering, what would be the procedure to migrating over existing postfix mail to the new machine? Is it as simple as copying over /home directories and /etc/passwd etc?

Long time lurker, still a Linux noob but Im learning I currently have a home media server setup with the following hardware specs:
MSI P45 motherboard
Intel Core2Quad Q6600
8GB DDR2 RAM
2x 250GB WD HDD in RAID1 via LVM (boot/swap etc)
8x2TB Hitachi HDD in RAID5 via mdadm (media/data)
The server mainly serves files for HTPCs around the house and runs a few VMs with VMWare server. I have recently picked up the following hardware which I�m thinking about upgrading to:
Gigabyte EX-58-Extreme motherboard
Intel i7 920
12GB DDR3 RAM
My main concern is will I be able to just swap the driving into the new system and everything can just pick up where it left off? More specifically, will mdadm be able to detect the 8x2TB drives attached to the new hardware and re-assemble the array?
My buddy that helped me set this system up isnt sure so I figured I ask here first, the boards do have the same ICH10R southbridge providing 6 of the SATA ports and 2 more will be run off of the extra controller onboard. I dont have a lot of Linux experience switching out core parts but in Windows Ive had great success moving things between various Intel chipsets and architectures from P965 -> P35 -> P45 -> H55 -> X58.

I have a friend that want to migrate his server to a open source mail system. Currently, he's using a system using Maildir. So I decided to use qmail since it has support for Maildir and it has pop3 capability. Courier-imap is the one I'll be using for IMAP. My concern is webmail. Can anyone suggest a webmail that will run using Maildir format and has addressbook and calendar feature. I'll be using a single server only. Please exclude Squirrelmail from the list.

Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

I am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?
Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.

I'm in the process of testing upgrade -yes, upgrade, no fresh reinstall of my old trusty 11.2 to the unknown 11.4. One of the applications I need is VMware. I'm using vmware server, and I'm thinking of migrating to the player version, because the server is
not supported, it seems.I have installed a small test partition with 11.4, and in it I have installed VMPlayer. It looks nice (I had to install a lot of development packages, gcc, kernel-source, etc - nothing new here). Sound in the guest (I'm testing my virtual Windows Me) works; it wasn't working in the server. Nice surprise.
One missing feature is snapshots. The trick is to simply replicate all the files of the virtual machine to a backup. It is huge space wasted, 9 GB for a small machine, but it is doable. One thing I do not know how to do: VMplayer gives a notice that the virtual machine is version "Workstation 5.xx virtual machine", and that this version'x CMOS is not compatible and will use a default cmos instead. But I have not seen anywhere how to choose or change or upgrade the virtual machine type.

After updating to KDE4.7, and upon opening Contact I was asked if I wanted to migrate to Kmail2 now. I said no as I was told that the migration would take a long time. I thought it would ask me again for the migration the next time I would open Kmail. But no, I now have kmail with no past emails, no adress book no nothing. Is there a way to start the migration again.

I haven't used this tool for a couple of months now and in that time I've had to reinstall ubuntu 10.10 for other needs. so I've gotten the tool back because of certain characters that ubuntu won't recognize, but I'm having an issue with it. I get this when I try to run it: Your current encoding was not found, or you are using the C Locale. Please pick a supported language from usr/share/i18n/SUPPORTED and log in again.
I'm not sure exactly how to do this and wanted to ask here first before I screw something up with the unicode. Also this hasn't happened to me the first time I've used this, but also I didn't perform or install as many other options and devices as last time either.

My wife has decided to give linux a try. I've installed Mint Linux 10 for her.Last week (bad timing) I converted her to Thunderbird. Now I have the task of moving all her mail folders and account settings from Thunderbird under Windows 7 to Thunderbird under linux.Other postings say all I have to do is copy the Windows profile directory to her home directory and rename it .thunderbird.
Doesn't work. When I start Thunderbird all it displays is a window for new account details.I tried just copying the <gibberish>.default directory across and renaming it to the one that was there. Again, no luck.Before it started using sqlite things were simple!I backed up with MozBackup, and then noticed that it only works with Windows.

I want to change my old computer,but i want to keep my software.I know that i can install operating systems on new computers' hard disk and then transferring files and settings is possible,i also know that ,i can copy some software on DVDs and use them on my new PC,but ,i do not know exactly how to migrate my operating systems without any loss or disorder. Regarding that my hard disks on old computer,can not be used on new computers because of their connection cable to main-board(sata),although it might be temporarily possible by connecting them to/as CD/DVD ROM site ,so how do i transfer the whole data to new hard disk,without any loss or disorder,and how to configure that all? I ask this because i know some programs do not work if they are moved (even in the same computer) and,operating systems are installed(and configured) in a computer,so is it possible to transfer this installed operating system with a new configuration ? I need this transfer because in many cases i have lost the main source( CD,DVD,or downloaded files,and also some operating systems need activation and or registration,buying and,i won,t be able to install them again.

The thing is I need a bigger server, but at the same time I'm having problems with cpanel and centos and I'm quite bored. So now I want to migrate from my cpanel server to the plesk server keeping the domain and it's content. I tried to create a ticket in plesk support but either I didn't bought the server yet. So, what's the quickier and safest way to migrate? Is there any script?
