Ubuntu Servers :: Easiest Way To Move 200 Accounts To New Server?
Feb 9, 2010
I'm in the middle of moving my lab to a new server in the middle of the school year.. and need to copy all the user accounts to the new box, hopefully with all the student's passwords and contents of their folders intact.And since we are using the system daily, I need to do it all in an hour or 2.I'm thinking I can just
1. diff /etc/passwd and /etc/shadow from the old the new
2. copy all the student folders to new /home
3. write a script to set the permissions on all the new /home folders to match the user names.
It seems easy and safe so long as I back up the 2 existing files..Any reason not to try? Or is there an easier way?

I've just made my old, dusty computer into an Ubuntu Server. So far, i have installed a well functioned LAMP server, to host my Website. I have also installed a FTP-Server (proftpd) and i was wondering if i could manage my FTP accounts in MySQL so i could make an account creation page for it? If yes, how?

I googled for a while without finding anything about this, so i created an account to make sure that others after me get an actual hit when searching for an answer.I have 13 email accounts in Thunderbird for work-related stuff. Thunderbird by default just adds accounts in a top-down manner without sorting of any kind, not even alphabetically. For most users this is not an issue, but for me and other powerusers who have multiple accounts with an uncountable amount of subfolders it soon becomes a nuisance to have your latest added mailbox all the way down when you actually check it quite often.
Why Mozilla havent included a simple drag'n'drop feature or similar for this is beyond me, but here is how you do it.For example if i wanted my latest added account - which is placed all the way at the bottom by default - to instead be placed at the top of the list, i just delete "account4" from the end of the line, and insert it at the front. Make sure that there is no trailing comma and no whitespaces anywhere.There we go. I hope someone finds this useful, a bunch of my colleagues sure did.

I'm looking for ideas on how to transfer a group of xml files from one server to another server, either in a regular interval or ?I have a listing program, it creates a directory or classified ad type listing. When one of these is created, or an existing one is edited an XML file is created. I need to take these files and get them to another server. I've read about SOAP, FOPEN and of course FTP.

I've running my mails from 3 domains on Google Apps for several time, but I think it's time to set up my own Mail-Server now. I have a vServer and want to migrate my existing mails after setting it up. Now I have 2 questions.
1. Which components do I need / do you prefer for a mail-server(imap, smpt, webinterface)?
2. How do I get all my existing Mails in there?

We have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.
Some information on our web server code...

I have somewhere between 8 and 12 servers, spread amongst different webhosts, all running CentOS 5.3. Everything on the servers has been compiled from source:
> EngineX, PHP, MySQL, Munin, etc
I compile from source because I usually run ./configure to modify the source before installing. What would be the easiest way to keep the server software updated? I am considering creating custom packages from a server which I would keep up to date manually. Then use Capistrano or Puppet to install those packages on all of my servers.

I need to setup a mail server, purely for relaying mail to a MS exchange server. A previous employee used Postfix on CentOS. I have limited Linux knowledge and no experience with any mail server software other than MS Exchange, so we cannot continue with this solution (unless I can find a way of managing it all from a gui). Does anyone know of an MTA that can be configured completely by GUI? Everyone says sendmail has millions of features and loads of documentation, but I simply do not have the time to learn it. I need something that can be configured with minimal knowledge and via GUI, not command line. The only reason I'm not using Exchange is to try to save money, and hopefully it will be more secure.

Are there programs for this? Really really simple page layouts that you can edit and host from a graphical desktop that has your web browsers and Pidgen and VLC media player and everything running on it at the same time?

I am unable to join a W2K or XP machine to a Samba PDC. I have tried to make this work on both 8.04 LTS and 10.04 LTS without success. Everything else works but I cannot add machine accounts "on the fly" using the "add machine script" as provided in the server guide. I have been able to make it work by enabling the root user but not as a user with admin privileges and sudo in the script. Despite multiple attempts including a new 10.04 install and following the instructions (in the 9.10 server guide) to the letter. Does anyone out there have a samba PDC actually running on Ubuntu and able to add machines on the fly without enabling the root account (i.e using SUDO in the script and a user from the admin group)?

I recently Re-did my Postfix configuration using [URL] The thing that that guide did not tell me was how to get email to forward to other accounts or if I can point multiple accounts to the same place like here:
[Code]...
finally I tried putting a .forward record in /home/vmail/domain.com/username directory which didn't work either.

We have a small network consists of 5 servers, providing SSH for several groups of users. We want the users (e.g., me) be able to log in to any of the servers with their own account. So, we define the user accounts in a server that runs NIS service, and configure all the other servers as NIS clients. We also defined several groups for different user groups, so some users belong to several groups. All the user information is populated by NIS. This setup is working in Ubuntu 8.04, AMD64.
Now I upgrade the servers to Ubuntu 10.04 64Bit. The problem is, now if I log in to one of the NIS client servers using SSH, my group membership is lost. However, when I log in directly to the server, the group membership is retained. For example, in the /etc/group file, I defined the user tliu as a number of awww group:
Code:
tliu:x:1004:
agroup:!:2000:tliu,ian,verickson
awww:!:2010:tliu,bstark,verickson
[code]....

I'm using vsftpd as my FTP server. I have set it up so I can access my home directory via FTP, requiring my login.
But I want to make a folder in my documents (or anywhere really), which only my colleague can access. But I don't want to make a local Ubuntu user account. He just needs to be able to send files to this folder, connecting remotely, using his own login details.

I want to use AD sys accounts to logon to linux servers. What is the best and most secure way to do this. This because we want to ensure it is tracable when a server administrator makes changes to a linux server. Now we use root to make changes to the servers.

I have a problem concerning about launching Firefox from NIS accounts. But it works perfectly if is started on terminal by the the local root account.
I have several hosts that's connected to a NIS server. When I tried to launch Firefox from one of these hosts, I got no response (Case 1 below). Here are the scenarios:
Case 1 - Fail to launch Firefox as NIS user: I login as NIS user account on the host, then I tried to launch Firefox by typing "firefox" on the terminal. But then I got no response from the terminal (the web browser didn't appear on the screen).
Case 2 - Success to launch Firefox as root: I login as root on the host, then I tried to launch Firefox by typing "firefox" on the terminal. The browser has appeared on the screen.
Case 3 - Success to launch Firefox as NIS user: I login as NIS user account on the host, then from a terminal, I login as root (using "su"), then I tried to launch Firefox by typing "firefox" on the terminal as root. The browser has appeared on the screen. Then immediately, without closing the browser window, I opened a new terminal as NIS user, then I tried to launch Firefox by typing "firefox" on the terminal as NIS user.

I've been tried to be system admin, programmer, network admin, or network engineer. So, I've been studying this and that... what so ever struggling to find my talent. Back in 2007-2008, I was MS server admin/comm tech. I saw a building running MS server for user computers and Red Hat 9 as a main system server. MS sever was a just one of the user accounts of Linux server. When I log in to Linux, I could see log menu to access MS server. How could somebody make this creative thing?I'm now a Network engineer because working with CISCO router and switch is easier than working as programmer or server admin. I've studied Oracle 10 and VMWARE also but there are ceasless stuffs that I need to study... For now, in regards of my limited brain power, network engineer is proper for me.

I am thinking of getting a domain name or ten I do not know were to point the domain to?
and what do I need to setup if a user wants a domain name to point to his account on the server? ok more like I want to have a few domains pointing to my user accounts I have setup on the server..can I do this directly or do I need a server domain first before users can get a domain name?
I have a basic setup user web space and ftp and mysql setup
what extra would I have to install or not to be able to get a domain pointed to my server and/or user accounts?
I don't seem to be able to find anything specific on how to set this up anywhere.

I am kind of new to servers and need to set up a server in the lab (for 4-5 clients). I heard ubuntu has a different server edition. But I already have ubuntu desktop edition so I was wondering if I really have to install a server edition for my limited functionality. If it is not required to install a full blown server and I can do with the one I have, how do I go about creating accounts for remote login?

We have a web server and are trying to meet a clients requirementes around accountability.Basically, everything in the system should be accomplished using user accounts that are individually identifiable. So basically, no root user, since that's anonymous.So how should we set up these user accounts?Being administrators, we want them to have easy access to files not owned by them, such as ones uploaded using FTP accounts or via apache.We want to be as secure as possible though.
My current thought is to add them to the root group so they have full read access throughout the system, and add them to sudo, but I worry that gives them too much control.

I googled a lot but I didn't find anything about this. I have multiple accounts on the same ftp server (the server is not mine I don't access its configuration)
If I write ftp://hostname on the location bar it lets me login, but only allow me to be in only one account at a time. Putting ftp://hostname on the location again just opens the account I logged into and I'm unable to login to the other account to move files between them conveniently.
Is it possible to log into multiple accounts on the same server?

at the moment we're running an isc dhcpd with about 300 clients to serve. Because of inconsequent maintaining i think we have about over 50 dead static client entries in our dhcpd.conf. So we want to change our construct.Our aim is to allow a mac on the dhcp server to get an ip address. If this mac hasn't registered an ip address from the dhcp server for a time more than 90 days, the host entry gets disabled or deleted automatically. I'm searching for such kind of dhcp server configuration for many days. Have you any idea if there is a possibility to implement such a configuration?

I have recently discovered the following: when I attempt to connect to any of our machines that are OpenSSH 5.x (Ubuntu 10 or OpenSuSE 11.x in our case) as one of the users defined in the NIS domain that fails. For instance, me (user bepstein) can SSH into all those machines but not SFTP.I can SFTP into those machines on the network that are OpenSSH 4.x, however (CentOS 5.3 - 5.4, OpenSUSE 10.3).As a user defined locally on the machine (in /etc/passwd ) I can connect via either SSH or SFTP even if the machine is OpenSSH 5.x.Some further discussion of that issue is available here: http:[url]....

Has thunderbird (recent version) have a "TEST" function ? basically, i'm trying to send messages, with 20+ accounts (different emails, but one domain / SMTP server). one account works fine - the other one doesn't. i go to my "outgoing server" & everything is fine - usernames / ports etc..) The settings for each account do show the right outgoing server. If i 'send later' & close down thunderbird, 7 re-open - it asks me for my password again (which it saves), & then it is able to send the email.
QUESTION :- is there a TESt option that will test each & EVERY account in one timeslot ? Ie, will go through each email address - sends an email to itself (the same address), & sends it. it will then try the server again, to see if the email was received. & then give me a single report, of all the incorrect settings.(I've tried this 1 email account half a dozen times tonight & i dont know *WHY* its not sending on the 1st go.. )
