CentOS 5 Server :: Centralized Storage For Windows And Clients?

May 26, 2011

I have setup openldap and samba for authenticating Windows and Linux clients on my server. They are working fine. Windows users are getting authenticated through server as Primary Domain Controller and Linux clients directly from Openldap directory. But I have little problem that is I want to mount home folders created on server to be available on clients so clients get a centralized storage with some quota on both Linux and Windows clients. Can you help me please how can I do that.

Ubuntu Servers :: On Building Home Data Storage Server?

Jan 18, 2010

I need some advice or tips or maybe your own experiences about building a home data storage or NAS.Here's some thoughts / requirements I think it should have:It should expandable. I'll stick a couple of 1TB HDDs and a little later I'll stick some moreIt should easily integrated to both Ubuntu and Windows 7. Ideally it'll be an integrated part of the filesystem.I'm thinking some sort of RAID as a backing up my data. RAID 1 seems like a such a waste but then again, these days, HDDs are cheap.And when I do add more HDDs, I'd like them to appear as one big storage unit instead of separate drives.Any suggestions and tips on how to go about this is welcome. Questions are plenty: should I go with server hardware or is bigger ATX case and standard hardware enough? I'll need some pointers so keep 'em coming

Server :: Recover RAID5 Storage Array DATA Using Xfs_repair?

Jul 5, 2011

I have an Acer Altos EasyStore SATA NAS box that hung, the only way to reboot was to crash the system (unplug it). Upon reboot it was not recognising the hard drives (it wanted to do a destructive reinitialize). Most of the importent data was backed up, however some was overlooked and we'd quite like to get it back. Removing the disks and placing them in a PC with enough SATA bays to cope, and booting with a live linux distribution (System Rescue CD) I can see the 4 drives are not suffering hardware error and that the original partions exist. Using mdadm I can assemble the Arrays without error (seems to be three but the only one I am concerned with is the RAID5 array of about 3TB). /dev/m1p2 mounts as a loopdevice once an offset is entered. In turn this mounts as an XFS parition. However despite df showing the partition almost to be full. ls -l or ls -a on the mount point shows it to be empty!

I got thusfar using a translation from a German language forum, unfortunately I only speak a little German, and the only other English language post on a simlilar matter I found within that site had no replies. The next step was to unmount loop, then run xfs_chack and xfs_repair on the file system. xfs_check returns that there is are a few dir size and offset errors along with link count mismatches. This I would presume normal for a file system that has become slightly corrupted. xfs_repair (version 3.0.3) gets as far as Phase 3 it finds and corrects zerolength entries, offsets on directories and bogus inode numbers. However the final two lines are:

Code:

realloc failed in blkent_append (2671166480 bytes)
zsh: segmentation fault xfs_repair /dev/loop1

A search on the error missing out data size just returns code to generate it, is anybody able to explain what it means? Also remounting hard drive, ls and varients of still do not return anything. Am I missing some thing (root I am logged in with now would have different credentials presumably to root on the NAS box, so how do I get around this)?

Software :: Centralized Log Server With Web Gui?

Sep 24, 2010

I want to set up a centralized log server, and I have several requisites:

1. The ability to view multiple log files via a web interface or browser.

2. The server's ability to send e-mails to the administrators when a critical condition occurs within the log files.

The logcheck application seems like a good start. However, it does not have a web gui so I was wondering if anyone can recommend a program that either works with logcheck or has the above two requisites on its own.

Security :: Mounting Centralized NAS Server With NFS?

Mar 24, 2011

- we have a bunch of linux servers.

- lots of users work with linux Desktops. They use them as testing servers.

- All the infrastructure has the Authentication services linked by Quest Auth Services againts an AD. This gives us the option of logon scripts, startup scripts, and other things.

- One interesting option this Quest thing gives us is SUDO management. We can edit sudoers file by GPO politics.

- Now we are deploying a NAS server from Hitachi with cifs and NFS mapping capabilities.

- Servers are managed by IT, so nobody can go root except us.

- Desktop users will also mount the NFS shares so they will be able to work with real data and read their own data from servers.

- Desktop users can go sudo su.

- If desktop users go from root to another user, the NFS let them work as they where the other user.

I would like to keep them from swithching users, but only between AD users, they must be able to switch to apache user or postgres user.

Ubuntu :: NTFS For Data Storage?

Apr 13, 2010

I'm now having to access a lot of data on a portable hard drive on a regular basis. The drive needs to be used with three different Windows systems, three Ubuntu machines and two slackware units. The data is backed up once per week.

I have been using Ext2IFS to access the data (stored on Ext3) from Windows but keep having problems. Obviously Ubuntu and Slack have no trouble reading or writing to the drive. Additionally, some sensitive data will be put onto the drive shortly and I would like to encrypt it.

What is the best solution here? Is NTFS reliable enough and is data access and writing reliable enough from Linux? Can I encrypt NTFS and still leave it accessible by Linux? What is the best software to encrypt the drive with (if I can) that is accessible by both Windows and Linux?

Server :: Cluster Storage With The Rock Cluster Storage Operating System?

Jun 8, 2010

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.

Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.

then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.

PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

Ubuntu :: Does An Ext4 Filesystem Being Used Only For Data Storage Require A Swap Space

May 6, 2011

I am running a dual boot system with Win7 on /dev/sda and Ubuntu 10.10 on /dev/sdb

I also have a 250 GB disk I use for storing backup data, /dev/sdc

The two logical partitions on /dev/sdc (/dev/sdc2 and /dev/sdc5) each take up 2.86 GB and I would like to free up that space if possible.

Since the filesystem on /dev/sdc doesn't have an OS on it, does it still require that those two logical partitions exist?

Hardware :: Data Storage Locations Of The Separate Devices Involved In Booting Requested

Oct 18, 2010

I'm trying to get a complete overview of booting so I can multiboot. An explanation of the hardware that stores data and the hardware that runs it with the paths the data takes would be awesome!

Here are some quotes that are not comprehensive.

Quote from [url] "When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program."

System Memory is your RAM is it not? Why are they being specific in stating the address location in the Firmware that BIOS uses? An external EEPROM on the board is totally different from RAM is it not? Does the BIOS data travel to a specific RAM Location?

Is there a small processor connected to BIOS or is everything run with the Main CPU?

What exactly is the "chipset" that is referred to with booting?

Debian :: Building An All-around Homeserver?

Nov 26, 2010

I have been meaning to do this for awhile. I have a relatively decent machine currently running FreeNAS, a BSD based NAS system. It works great as a NAS box, but now I want it to do more. I want it to act as a file server/NAS, also as a router for my home network, so obviously I will add a second ethernet port as well as wireless "N" capability. As a router, I want to have fine control over my home computers. And, I have a multiple camera security setup, using Motion, that I want to run on this machine 24/7. I know Motion doesn't take a huge amount of horsepower, since I am currently running it on an inexpensive laptop running Squeeze.

What I would like advice on is how some other people on this forum would accomplish this. FreeNAS works great for what it was designed for, as well as IPCop, but neither will do all that I want, so I plan to run Debian on it, most likely Squeeze, as it will soon be Stable.

OpenSUSE Network :: Fileserver - Homeserver ?

Sep 19, 2010

Okay, I've been using openSUSE on and off since version 10.0. I have enjoyed it quite a bit. It still hasn't taken over as my main OS, but I have installed 11.3 on my netbook and it is the primary there.

Here's the issue though. I have recently acquired an older HP fileserver. It has a 1ghz PIII, 756mb ram, three SCSI hard drives, as well as a tape drive back up. All in working condition. The motherboard is even a dual socket (multi-processor) motherboard, and I can get a matching processor for around $20 - $30.

I would like to turn this into a server of some sort that I can use at the house to share photos/music/documents/movies etc. Now, I am assuming that if I was using linux completely for all the computers in the house it would be easier to network all this. However, this is not a reality. My wife's computer uses XP Home and this is what she wants. My desktop dual boots Win 7 Ultimate and openSUSE 11.3, and the netbook dual boots XP Home and openSUSE 11.3.

How would you go about setting up the HP as a server. I plan on adding a couple of 500GB hard drives for the storage and possibly purchasing the second processor. I have a linksys router, a zyxel wireless router (set up as a wireless switch) and a 5 port workgroup switch. So attaching everything should fairly simple.

Ubuntu :: U9.10 Homeserver For Fileshare - Samba?

May 14, 2011

I'm relatively new to linux, but i've learned some stuff and still have some goals. I'm seeking some advice on the best way to proceed. if this question is well answered elsewhere, a link to that would be sufficient.

my goal: use a linux box as a password-protected (read/write) fileshare server on a home network, for compatability with windows 7 machines. Files/drives to be shared are on external hard drives for volume reasons.

What I have accomplished so far: ubuntu 9.10 up and running on old desktop using php5, phpmyadmin, mysql - got http home page set up that is accessible over home network remote desktop is enabled, works successfully
external hard drives mount automatically in ubuntu, data is accessible/usable SAMBA is downloaded. Is Samba the best way to proceed? I've tried to read up on the samba's docs, but I still don't exactly understand What it is or How it works, and also whether it will work with Windows 7 Home pcs. do i have to dl software for the windoze pcs, and mess with the registry? is it worth it? Ideally I want other home network users to be able to access the fileshare server without having to mess around on each individual computer....

Are there other options? Is there some way I could mount my external HDs in the folder that my /var/www folder that the server automatically references, and make some kind of http-based directory navigation for file transfer? Would password protecting the home/index page be sufficient to ensure some amount of security? is some kind of FTP a better option? whats a good program or link to check out for ftp?

OpenSUSE Network :: Network Login Starter - Set Up A Server - Centralized Username And Password

Jan 21, 2010

I'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.

Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.

What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication

Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").

So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.

I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.

Ubuntu Networking :: Unable To Access SAMBA Shares Hosted On HOMESERVER?

Jan 6, 2011

I am traveling to the UK next week, and whilst I am there, I need to be able to access my SAMBA shares hosted on my HOMESERVER, via my laptop in england.

I have tried Hamachi before, which works fine on windows, but the linux version is awful, and hardly works. So I need an alternative. I did a bit of googling, but I don't know what "bridged" means when I found a OpenVPN tutorial

I was wondering if anyone could give me some information as to what I'll need, and what I'll need to do on both my homeserver and my laptop?

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.

how both storage devices will be supported by Ubuntu or Debian??

Server :: Building A Storage And Vpn?

May 15, 2011

I am trying to figure out the best server configuration for the following:Low power (I want to plug the server in and forget about it)High redundancy of data (I don't want to loose my music and documents!)The ability to stream music + movies to laptop (maybe subsonic or Jinzora)VPN server with IPsec or OpenVPN NAS $800 budget 2TB with ability to add more drives :Unix Server with software RAID (maybe RAID6)

VPN setup on virtual OS via VirtualBox
NAS setup on virtual OS via VirtualBox

My Questions:What would be the best raid configuration if I wanted at least 2TB of data and the ability to add more disks when the space begins to add up?What would be the best OS to use for setting up a software RAID (is a FakeRAID a better solution)?Does it make more sense to separate the VPN and NAS with different OS's?My goal will be to access my data from any computer from anywhere but mostly just my Laptop from work.

Server :: How To Best Configure Storage Space

Mar 25, 2010

I'm building an Ubuntu 9.10 home server to essentially backup all my PCs to, serve media, and store other large data (I record music and film). Here's what I have as far as storage goes:
4GB CompactFlash: for OS
2x 500GB WD drives: intended for RAID-1 for backup (which I will in turn back to external drive on a weekly basis)
3x TB Hitachi drives: intended for RAID-5 for media and storage

Both RAIDs will be software-driven. Now, a few questions:
From what I've read, I can benefit from using LVM on top of the RAID. Is this true, and besides the complexity and potential difficulties in recovery in case of disaster, is there a downside to LVM?
Would I benefit at all from using smaller logical volumes on the RAID-5, or should I just make one at the full size of the drive?

Also from what I've read, it seems that XFS may be the best filesystem to use, from a stability and performance standpoint. Should I go that route, then? I suppose that if it IS beneficial to have multiple smaller logical volumes, then there may come a point that I need to shrink and grow these logical volumes, and if that's the case, it appears XFS is out of the question. What's the runner-up; Reiser? I currently have /swap and /home partitions on the CF card. I'd at the very least like to remove the /swap partition and just create a swap file on the RAID-5. Should I move my /home partition to the RAID-5 as well?

Server :: Using EMC For Storage - PowerPath And Qlogic

Jul 8, 2011

In our environment we are using EMC for storage. We are using Qlogic provided drivers and PowerPath and the OS is RHEL5.3. Currently we have 2 Luns connected in one of our server (emcpowera & emcpowerb) and storage team has allocated another 100Gb Lun to that system, my doubt is if I execute "ql-dynamic-tgt-lun-disc.sh" script that would be enough to detect the Lun and see the device under /dev/ as emcpowerc or I need to execute "powermt config" and "powermt save" commands also.

General :: Home Media And Storage Server?

i have a spare computer and 4 hds and was planning to make this computer a storage server with a media place aswell... i do have some linux knowledge but never used it for this and am not sure how good it will be initially the media files are in an HD with ntfs format which i want to keep as is... but i was wondering what options i had to make a media folder over network where i could browse and watch from any computer in my network ? is it samba my only options or is there a more media like solution for this ? There will aswell other features i was planning to use on it which made me think of linux, for example, svn server, websever with mysql to testing my applications, connection manager, all these i am sure on how to make and setup... but i am not very familiar with samba hence i am not sure if it is the best options for file sharing aswell as media sharing and/or my only option.i also heard that ntfs might be trouble some for linux in some cases

General :: Clean /var Storage On Dedicated Server?

Feb 4, 2010

The /var directory is 97% full on my dedicated server:

I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).

I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.

I have Putty Access to root but do not know which command to use.

I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.

My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.

I have only a very basic understanding of command line but really need to get this sorted ASAP.

Server :: Creation Of Clustered Storage On CentOS 5.5?

Sep 25, 2010

What I am trying to to is set up a cluster as follows:

- There are four nodes
- Nodes three and four have large amounts of storage that will be used for storing user data.
- Nodes one and two will be running a couple of network services.

I'd like have nodes one and two to have a clustered filesystem just between them to store data for the services run only by them.is it possible to share one filesystem between two nodes and another filesystem between two other nodes? The cluster seems to try to make the storage changes across all nodes. They will not be able to spend the extra money to get the same storage in all four nodes. Here is what I have done. I am using CentOS 5.5. After installing CentOS, I did this:

On all nodes:

Code:

[root@node1 ~]# yum groupinstall "Clustering"
[root@node1 ~]# yum groupinstall "Cluster Storage"
[root@node1 ~]# chkconfig ricci on

[code].....

...which I think makes sense because the cluster was supposed to create the PV and the volume group, but did not. I don't even think it tries. The first time it tries to do anything to another node is when I create a logical volume.

Software :: Secure Storage - Message Server?

Dec 2, 2009

I'm trying to find a program that will allow me to run my own server for secure storage. Ideally, this server will allow me to set up separate users. I've heard of solutions that will automatically email the user when a file is placed in their folder, and the email will contain a link with a session ID that expires after a preset time.

Security is a big deal here as well. Something above and beyond SSL would be ideal, like GPG or PGP, so nothing is ever transmitted in plain text.

This would be a server that is accessible from the internet, and would probably be running on a CentOS system.

A vague description, I know. I'm going off of what others have told me they've seen/used in the past. Now I have a boss that wants to use something similar, but trying to find anything that sounds like this has proven quite difficult. I'm hoping someone here knows of something that might work.
