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.
I have been able to accomplish my goal of creating an AD-like authentication using LDAP,SAMBA and LAM. From what I have seen you can have this type of setup but it doesn't allow the passing of group policies to the desktops of the users.
i want to run a homeserver here for centralized data storage and more...features required:
client compatibility with most Linux distributions, MS Windows 2000, XP, Vista, 7, XBOX! harddisk shutdown if not in use (got some real noisy ones) easy administration?! (maybe web-based?) security! no files or folders over the internet (yet)
i have Centos 5.3 installed with TXT mode i want to create and share one folder to be accesible to me from the network, to download and share files into it with my Host, i created the folder but dont know how to share it,
I am stepping into Linux world ...and I have chosen CentOS. I have installed CentOS 5.5 on a dedicated IBM server successfully. My server has two network cards. I have configured eth0 for lease line internet connection with a live IP (113.xxx.xxx.xxx) and eth1 for local LAN with a static IP (192.168.0.1).
Now, 1. DHCP is working fine and I can access the server from my Windows XP clients. 2. I can access the server with SSH client PuTTY from home ( with the live IP ) and from the local LAN (with static IP 192.168.0.1) 3. I can access my shared server directory 'public' from my XP clients 4. Internet is working on sever and I have updated the server with yum update.
But, I cannot access internet from my XP clients machines.
I read "The Definitive Guide to CentOS" and tweaked the config files in different ways but it did not help. now after two sleepless nights I am here as my last hope.
I admit, I am not aware of every linux terms and commands, but I am getting into it. code...
I have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.
localhost in.tftpd[12727]: tftpd: read: No route to host
I work for a church, with office staff of about 10 people.
We want to set-up a server to store all the office information, (which is now scattered all over the place).
The idea is to give individuals a partition on the server(password protected). There is database software that needs to be accessed by 5 people( it runs on MS Access). Most of the document are MS Word. Of course you can tell me of a better way to do this than my idea.
how to set-up this network. I have to submit my info to church leadership. it will save us buy Window Server and 10 CAL (that ZAR 10k).
At my work, we have several clients (outside clients) that have an FTP login to our FTP Server. Their login then leads them to their home FTP folder. The FTP server is currently a Win2003 box. Because we have so many clients, we would like to implement some form of WebGui that would allow each client to manage their own FTP home folder and user info, such as resetting their password if they lost it.
Is there anything like this available in linux that would provide us with that kind of control/usability?
I have a server (called NAS) that shares out /public, and I also have this same server running KVM with some VM's. I am setting up the first VM now, and one of the things it does is download torrents onto the share. I am connecting it via "mount -t smbfs //nas/public /mnt/nas" from the VM on the host and it seems to work fine. However whenever I add a torrent to the queue on the VM to download, all downloads stop and seem to be disconnected. I can restart them after a few seconds, but they will stop after a few minutes with another disconnect error. I have the network interface bridged, so I thought it was talking directly to the host.
Where 'xxx' is a date/time string down to the second.
Each subdir entry contains a number of files, depending on load at the time.
What we see happening is that a subdir will appear empty from a client (ls -la shows . and .. ) but an rmdir will fail with a 'directory not empty' error. From all 7 clients (mix of Centos 4 and 5). However on the server the files are visible. If we 'touch' the files the clients will then pick them up and process them.
It doesn't appear that waiting any amount of time will make the files visible (we've waited 8 hours while testing).
We've tried different mount options, NFS4, etc. Nothing got rid of the issue. Changing one server to use CIFS however solved it. So it appears to be some bug in NFS.
The problem appears to be intermittent and random, we can go hours without seeing it, or minutes. I'd say it affects fare less then 1% of the files written.
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:
...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.
We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.
I have a network consisting mostly of Windows Vista and 7 clients and an Ubuntu server. The server provides both the DHCP and NTP services through dhcp3-server and openntpd. In my dhcpd.conf, the subnet is declared as follows:
The clients don't seem to be using the NTP server though. When I capture the network traffic with Wireshark during the DHCP process, I also see no mention of the NTP option in the DHCP offer message. I am not quite sure if the clients would have to specifically request that option to receive it or if I have to make another configuration to offer the option.
in my office we are using redhat server and 20 windows client machine. some times while viewing the server stored files or not able to view.yesterday i saw a problem all the files are showing but not able to open a single fine after restarting the computer iam able to open the file.
I can't seem to get the X server to allow access from clients on other hosts. (I know, not exactly a network problem, but. I made the change in /usr/share/gdm/defaults.conf to be : DisallowTCP=false
and this worked on another CentOS system, but it hasn't fixed it on this one. What other things could prevent other clients from connecting to the X server? From the local host, I get :
Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed although the client DOES actually create the window and work! So, maybe this message is a clue.
From the remote host, I get : Error: Can't open display: 10.10.1.20:0.0 Which is not terribly informative. Is there a log somewhere which details why a connect request was denied? The files in /var/log/gdm are not very informative.
Don't work nslookup from clients guest OS.I have LinuxMint 7 and I'm installed VirtualBox on her. I created three guests OS. Two CentOS and XP
Name The first CentOS linux1.starline.ca The second CentOS centos.starline.ca The third XP xp2.starline.ca[code].....
On the clients guest OS nslookup don't work. It write : timed out; no servers could be reached .What is going on? Why nslookup don't work from clients guest OS?On client machine in the file /etc/resolv.conf have record ameserver 168.135.88.2
i have openldap server with phpldapadmin as a gui, i'm gonna use the ldap server just for address book.you can see in the picture how i built my ldap db.
I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.
I would like to install Linux based AntiVirus Server with Windows Clients. As per the existing setup, all Windows machines are using "demo" or "evaluation" copy of antivirus & all antivirus softwares are not same on all windows computers.
Someone is using Trend-Micro ,other is using Avast. Due to above listed problem,i want to implement Linux Based Free AntiVirus Server,which will be connected directly on the internet. The Linux AntiVirus server will updated it's database from Internet automatically.
Inside the Linux Server,all Windows PC's are connected in a same Local Area Connection. All windows XP computers will fetch the updated data from the Anti Virus Server. Also,i am searching MAIL RESPONDER OR POP UP Windows,when any virus found on any client machine. My company needs Cost Effective solution & Linux is the best solution for this.
I want to replace Windows AD with SAMBA I want to know what policies restrictions I can get in SAMBA as compared to windows AD - whether it is possible to restrict clients not to change IP, access cdrom or control panel.
I'm new to Centos 5 (and Linux) and, after installing Centos, I configured Samba, Apche, ... w/o problems (through interactive interface). My problem is tha t I need to use DHCP (all our clients use dynamic IP addresses for the ease) but I don't find dhcpd ... nor the sample config file(s).
Note : the new server I intend to use is actually connected on a LAN with an 'old' DHCP server (still under W2K server), is this the reason why I can't find/activate dhcp on my new machine ???
I have been searching for a software package that will install on CentOS5.4 x86_64 or RHEL5.4 x86_64 that I can allow users to access via the Internet for online web storage, pictures and they can manage their space (quota would be enforced). I am not having much luck finding any software?
I have to set up a box which can manage all the logins in our company and has the feature to manage every possible permission with as much comfort as possible. We are using Linux and AIX therefore my Boss is willing to switch from our Windows DC to a Linux DC. And here lies the problem, I don't really know what is needed to set the Box up to manage the Unix, Samba and LDAP accounts with one tool maybe?
I would like to know which Software exactly is needed and how to manage to get the thing to work together with a security aspect. I configured a Samba DC with LDAP, Kerberos and TLS but it looks like I overdid it because Kerberos is not able to manage the things we need in a manner that the other Admins in my Company would get things done in a short time.
Therefore I would like to get listed all the Software needed and maybe some How Tos how to get thing working, because I am losing my nerves on this matter. In the last 3 weeks I have set up several test boxes but every time something doesn't work. My biggest Problem is to get Samba and LDAP to work together with TLS or another security scenario.
I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.
