Server :: Setting Up Network Share With Multiple Drives
Aug 12, 2009
I have what will soon become a file server here running Mandriva 2009.1 and I need to set it up for use. There are 6 physical drives, sda-sdf. According to my fstab (pasted below), the OS is installed on sdb.. and for some reason I have a swap partition on sda and sdb. I had a horrible time getting a working installation, and that's probably leftover from a previous attempt.
Question 1: Can I simply edit my fstab to remove the swap on sda, effectively confining all system resources to sdb? The end result I want is all storage space over all drives accessible from a single mount point which can be accessed over the network.
Question 2: Once I sort out the weird fstab, what's the best way to go about setting this up? I imagine I need to format & partition the other drives (all but sdb).. but as far as organizing the free space, what's the best way? Is it possible to have multiple physical drives accessible from a single mount point? Or will the users have to use each drive separately? I was thinking I could create a directory on sdb (in /home?) to use as a root for the network share, and then automount the other 5 physical drives there. Does that make sense?
I have been trying to move away from Windows2000 on Ubuntu for months. I have a few applications that I run on Windows that I have been unable to find usuable equivalents on Ubuntu eg Outlook/Mobile sync application required for my job and a DVB TV card application for home. So it looks like I am stuck ruuning W2K and Linux for at least a while and indeed I have been using GRUB2 to select between W2K and Ubuntu.
I need some basic advice about setting up GRUB2. My philosphy when it comes to PC data is you can never have enough backups and I avoid any single point of failure. So I have always used two hard drives which I keep in sync almost daily with FreeFileSync. I also swap my most critical encrypted data between a laptop and desktop. Then I also alternate external USB drives stored away from my home.
My current partions are
When I installed on the Ubuntu 500GB I let it & GRUB2 take the default options so it boots from Hd1 and I assume certain executables are stored at the begining of the Ubuntu partition as well as configuration files in its file system.
Now I'm replacing the 500GB with a 1.5TB and the old 500Gb will become my backup drive. I want to keep the backup drive bootable in its onw right. If either hard drive fails I want a bootable system and acccess to my data.
So my plan is to use the following partitions.
I can install W2K on the 1.5Tb from scratch or use Acronis to restore an image file. Then I can install Ubuntu from scratch.
OK now for my questions.
1) Can I get GRUB2 to put its executables and configuration files on a small partition of its own? I see no reason why they should be dependant on a specific Ubuntu partition. I have read posts mentioning this but not sure if this has to be a bootable Linux or just a file system with the config files.
2) Can I run update-grub on any Linux and store or copy the config files to the partition in 1?
3) I will use BIOS to determine which hard drive is first to boot. When I run update-grub (or when it runs during the new Ubuntu install on Hd1) I dont want GRUB2 to do anything with Hd2, not even know Hd2 exists, it that an option?
I have a computer, the one I am on now, with Ubuntu 10.10, it should be completely updated... and I can network with other computers, I can access Windows XP and 7 shared locations on other computers, and I can also get Ubuntu on other computers to access this computer's shared files.What I can't do, however, is share my hardrives that are on this computer, I have tried sharing them in /media/ and etc, but it is not working, apparently you have to mount them in some mystical way.
Another problem is getting Windows machines to access Ubuntu computers on the network - which I believe is a Windows problem, so I can figure that out some other time, but importantly, I want to be able to share my hardrives over the network.
If someone can give me some instructions to mounting and sharing hardrives(internal), and even my DVD-Drives, and portable USB devices, would also be fantastic - since, in Windows you can just right click, "share", and it's done.. It is a very useful thing to have, and I don't want to use Windows on this computer anymore, but I have no choice, really, if I can't share my storage to the other computers.
I use Samba, NFS, RSync and FTP/TFTP in my multi-location setup.
Is there a CentOS standard place to put my sharable file space? I've seen /usr/local/, /var, /var/samba, /user and /share. I have gotten to the point of preferring /share, but I want my servers to adhere to standards in case I am not available. Another alternative is to create a user name that matches the group name and using that user's home directory for the shared file space. This would solve the issue of shared departmental mailboxes and backups, not to mention (though apparently, I'm going to) SELinux configuration... Maybe I've just answered my own question...
i have ip's which are 1.1.1.1 and 1.1.1.2. If i log into 1.1.1.1 the outgoing ip shows up as 1.1.1.1 and if i log into 1.1.1.2 the outgoing ip still shows up as 1.1.1.1. I need to set it so that when i log into a 1.1.1.2 to shows up as 1.1.1.2 as the outgoing. Same for when i log into 1.1.1.1 it shows up as 1.1.1.1 on the outgoing end. I need to know how to set it like this. Anyhelp would be greatly appreciated. I am using my VPS as an SSH tunneling. I would to have it set up so that if i log into 1 account the ip will be x.xx.xx.1 and if i log into another account it would be x.x.xx.2 ect. I have been searching for hrs on thsi stuff and no luck at all.
I'm breaking into the OS drive side with RAID-1 now. I have my server set up with a pair of 80 GB drives, mirrored (RAID-1) and have been testing the fail-over and rebuild process. Works great physically failing out either drive. Great! My next quest is setting up a backup procedure for the OS drives, and I want to know how others are doing this.
Here's what I was thinking, and I'd love some feedback: Fail one of the disks out of the RAID-1, then image it to a file, saved on an external disk, using the dd command (if memory serves, it would be something like "sudo dd if=/dev/sda of=backupfilename.img") Then, re-add the failed disk back into the array. In the event I needed to roll back to one of those snapshots, I would just use the "dd" command to dump the image back on to an appropriate hard disk, boot to it, and rebuild the RAID-1 from that.
Does that sound like a good practice, or is there a better way? A couple notes: I do not have the luxury of a stack of extra disks, so I cannot just do the standard mirror breaks and keep the disks on-hand, and using something like a tape drive is also not an option.
I have configured a file server with samba and winbind in RHEL5.I am able to allot permission for the active directory groups to my Linux folder.No issues.But i want to set multiple groups of active directory to get ownership to a single directory. Say there are 3 groups a,b,c to have permissions to a folder of the Linux machine.
I set-up his mail server for him with Postfix but what he wants I have no idea how to do.
Essentially he wants it so that the mail gateway IP corresponds with the dedicated IP of the domain and I have no idea how to accomplish this.
I found some documentation on the web saying that the fix for this was to run multiple instances of Postfix which I tried doing but each time I try to start the second instance I get the error that postfix is already running.
There has to be an elegant way to make this happen, I really hate to tell a client something can't be done even though the concept is a bit pointless, IMHO. I am hoping I can get some feedback here on if this can be done and if it can the easiest way for me to accomplish doing it.
Here is some of the config files (example.com has been put in place of the actual domain names and the ip of 5.5.5.5 is in place of the actual IPs
I've currently got a centos server setup in my home. It has 1 website running on it and I am using DynDNS.com's service to access the server. DynDNS works by redirecting a free url to the IP address of your server. I would like to add a second website under a different url. However, I'm not sure how to add a second IP address (which I would then use with DynDNS to create a new url).
A friend of mine is starting a school this school has computers. I'm assuming windows but that's not that point at the moment. He asked me about setting a main unit that held the kids info and their work complete on the computer. Effectivley what I am asking is how do I set up a server to allow many multiple (at least 50 user at a time) each with their own folder as their home (or desktop I guess is a better word). He also wants a person to be able to add themselves as an account similar to that of signing up for something (ie facebook twitter you know). Oh and ( I almost forgot the most important) how to setup the server to allow the other computer to boot to it via the network...
I have a home Debian server running, and i would like to set it up as a gateway. I have 2 networkcards in it. So internet comes from the modem and on the other card i want to setup a dhcp server and it has to share the internet. But i want it also to connect to a vpn and share the internet of the vpn.. Is that possible?
I'm trying to set up quota limit in samba-3.0.33-3.15.el5_4.1 in CentOS 5.5, by means of the module vfs objects. In the samba howto [1] I found a very brief explanation, but it isn't working for me. The basic idea is to setup a user called 'quota2g' (uid 499) and setup the [homes] share, as it comes by default, to enforce the quota on each user share.quota2g:x:499:499:User quota 2GB:/home/quota2g:/bin/bash
So, at the moment I have a 7TB LVM with 1 group and one logical volume. In all honesty I don't back up this information. It is filled with data that I can "afford" to lose, but... would rather not. How do LVMs fail? If I lose a 1.5TB drive that is part of the LVM does that mean at most I could lose 1.5TB of data? Or can files span more than one drive? if so, would it just be one file what would span two drives? or could there be many files that span multiple drives drives? Essentially. I'm just curious, in a general, in a high level sense about LVM safety. What are the risks that are involved?
Edit: what happens if I boot up the computer with a drive missing from the lvm? Is there a first primary drive?
I have a fileserver that I want to share out samba shares. However, i configured samba to have another netbios (SAN) and my windows box still sees whoopn-SAN which is the name I gave to my server when i installed it. Now I am using 9.10 and I know that i can create a share from the gnome gui in nautilus and that appears to be a windows like share. How can I turn OFF the windows like shares that ubuntu does out of the box and use ONLY samba? I ask because there appears to be a conflict of permissions b/w samba and this stuff.
I am running a NFS share on a Debian Lenny server with to network interface.
Sometimes when booting the server the following messages i shown in syslog:
Code:
If the system is rebooted then NFS is functional again. I would like to know way this happens somtimes so i can repair it, anyone with an idea? Another thing is that i would like to bind the NFS service to a specific interface e.g eth1 is this possible?
Is it possible to use CUPs to share an already networked printer using IPP? The printer itself uses IPP.I know at first look this may seem like a silly thing to do, however I have a special case to set up a "print proxy server" due to security compliance reasons
[URL] To setup a web server at my office (intern). I'm stuck at updating the web server with the given distro's. We dont use DHCP and the computer must have static ip address. I've checked this in /etc/network/interfaces and from what I am seeing, everything is correct (ip address, subnet mask, default gateway, dns servers) however when I go to update I'm still receiving "temporary failure resolving [URL] etc"Is there something I am missing or something that I can change or check? Weird thing is, when I install the ubuntu live disk and have eht0 sets with these values, I can connect to the internet without a problem.
I am trying to setup my home server for test purposes. Now the IP I have assised my home server are 192.168.1.2 192.168.1.3
Port 80 is open in my firewall and Selinux is off at the moment.Now I have my DNS at my registar pointing at my home IP. Will that work? I have my name server configured with my local ip. Should I use my externel?
In my work I want to build up a Linux based network, where windows and linux clients are going to share a Thecus network drive.Each client will have specific permissions for accessing the samba shares. I have installed Ubuntu SRV 10.4 with gui and webmin.
I am setting up my home network. Currently, I have one computer (Munchen) which I have set in my router to receive SSH requests. This works just fine; I can SSH into that box from anywhere. I just put together a new computer, which I want to be a file repository, my ftp server, my http server, etc. What I would like is to be able to SSH into that machine from anywhere, then SSH into the other computers on that network from there.
Here is where I really don't understand the concept of what is going on. I can SSH past the router into one computer just fine either from anywhere (that makes sense to me). I can SSH from my new computer (Chemnitz) into Munchen (which is where the router points to and is running sshd) by using its local IP address, but I can't go from Munchen to Chemnitz (even though the server is running and the firewall should be allowing the connection). [URL]
Details of the system setup are below. Munchen (receives all port 22 requests now) Ubuntu 10.04 Chemnitz (I want to receive all port 22 requests and SSH into other computers on the network from it. Ultimately it will be a file sharing box, hosting a webpage, running an ftp server, etc.) Fedora 14
The office network has a machine we're using as a fileserver, which is running Windows Server 2003. There are several issues with this, but the main one is that the "Terminal Server License Server" was never installed or activated. I managed to do these things, but to continue requires retail keys which are long since lost. So the boss says we're going to make it into a linux server instead. And by we, he means me. A friend recommended Debian so my research starts here. i have a little experience running an ubuntu desktop at home, using the console quite a lot. And a little bit of experience messing with my own server. however, most of this is new territory for me.
The needs of the organisation:
1. We need a shared directory on the server which all valid accounts can access 2. We need a per-user directory on the server for each user, which only that user or root can access. 3. We need a per-user windows desktop, which only that user or root can access.
I'm trying to setup a media server for my Playstation 3 I've opted for the one off of this site PS3 Media Server now the installation instructions in the README don't really say much just make sure you have JRE 6 and run the script which I have done but get a message that I can't even began to cipher which is the following..
Code: ./pms.jar: line 1: PK: command not found ./pms.jar: line 2: h:: command not found ./pms.jar: line 25: h:META-INF/MANIFEST.MFManifest-Version: 1.0 Ant-Version: Apache Ant 1.7.0
share an external USB NTFS drive on my home network. The drive is attached to my desktop box running Debian Lenny. It's accessible on the desktop. I have a directory on the drive that I would like to make accessible to a Windows XP laptop. Read-only would be fine. The laptop has wireless access to the network.
I have OpenVPN running successfully on a CentOS Linux server. All remote clients connect without a problem and can ping the server LAN (10.5.0.0/24) . The server address is 10.5.0.1. All network shares on the server are available to the remote clients via SAMBA shares and this works well.The problem is that I am unable to get the remote clients to access services on the LAN clients. For example, there is a webserver running on a Windows XP PC (on the server LAN @ 10.5.0.2) with no firewall enabled. The remote VPN clients can ping this webserver at 10.5.0.2, but cannot browse the webserver at [URL]. All clients on the server LAN can however browse the webserver. The remote clients are using Windows XP and VISTA with OpenVPN 2.1.1.
I am new to VPNs and networking, but from my research, it seems as if this may be a routing issue. I would appreciate any help you may give in getting the remote clients to access the services on the LAN clients (other than the server @ 10.5.0.1).
I am putting together a server and computer lab at my school for Standardized testing, and am planning on using debian for it. But first, i must prove to the school board that this is a possible and viable option, so right now it is one pc with 1 gig ram (Going to be the server for this experiment), and two others with around 512 mb ram.the problem with all this is, the computers in the lab cannot have hard drives, as there is some sort of licencing issue. So I need to be able to have these two testing computers boot from the server's hard drive.
I have a server on my home network. It's currently running a DNS server (bind9) and an HTTP caching server (squid).What I would like to do is redirect all outgoing port 80 connections to the squid server and also make the server responsible for managing DHCP on the network.
Do I just need to install a DHCP daemon on the server, disable it on the router, then set my server as the default gateway and configure iptables to route all connections like I want? Or is it more complicated than that? Also, would that mean that all communication between two computers on the network will go through the server?
I have two NFS mounted dirs that the users want specific permissions set upon creation of dirs/files, independent from any other machine on the network.
We have a 10.0.0.x network with a working DNS Server (BIND) setup. Recently we purchased Watchguard firewall and configured three networks, so that our internal network can be divided into three networks and talk to each other through firewall routing. So I configured three ips 192.168.0.1,172.16.0.1 and 10.0.0.1 for local network card in the firewall router. I separated three networks and individually configured machines with static ip and given gateway as the above ips. Now, I need to configure DNS server for each zone in the same server which is in the network 10.0.0.x, is this possible?. If yes do I need to setup ip aliases for eth0 in the DNS server with different ips from each network?
