I want to have 1-tier client/server architecture using ubuntu edition. I have no idea how to proceed. I have many doubts:1. Which Ubuntu edition will be used i.e. desktop or server? 2. Which manual/book(s)/paper will best describe to proceed further?
View 4 RepliesI'm looking for a write one, read many file synchronization, file system or similar technique. In fact I want a to imitate a zfs_send/zfs_receive similar behaviour on Linux. My requirements are pure local (or in terms of distributed file systems: rack-aware) file handling with remote synchronization. Some random features/requirements I want to achieve are (I use the terms file and "file system" here interchangeable, as I don't care wheter I have to synchronize file based or use full file system supporting that):
Access on files from a specific host is pure local, i.e. the node has a full copy of a file, no parts are distributed. Read and write access is local, the remote side gets synchronized with write changes only Write changes on the remote side are non-blocking and asynchronous No need for concurrent file access, concurrent, distributed locking and so on Every file is changed by a single node only, other nodes have read access The file "owner", thus the node allowed to write files must be changeable Similar techniques (some as technology concept, not usable for me) exist, among those DRBD, MySQL Replication or even pure rsync.
I don't care whether I'm referring to a pure local solution (i.e. between two block devices) or a client/server mode. DRBD won't fit because its a peer to peer solution, I need to synchronize a lot of clients with a central storage through that way where DRBD just mirrors from peer to peer among two nodes and doesn't allow another node to take over the role of the primary node (i.e. node A is master, storage B secondary, I want to change to a thrid node C which becomes master and receives hence a full update from storage B.
Just as a guess, I'd make a local LVM volume on every node where write access happens. In the same time there exists a iSCSI target with multipath to a remote hosts which is shared with every node, again providing a clustered LVM. So I'd need to synchronize a local LVM volume with a remote LVM image. The question is just by which technique I could achieve that (i.e. as RAID 0, where every read and write goes to one node only and doesn't wait the other node to succeed). I could achieve this with rsync by a cyclic push to the remote host, but the problem is, that rsync isn't block based thus I'd need to synchronize every time the whole file, not only changes.

View 6 Replies View RelatedI do not know much at all when it comes to setting up hardware--servers, switches, etc.
I have a 1701HG 2Wire wireless router that I use for my home network. I have an old pentium 3 tower that is just laying around, and I want to be able to host my projects on it for testing. Basically, I just want to be able to do everything on my laptop and then upload it to the server for testing.
I have set up an Ubuntu LAMP server on the desktop and am able to do everything I want via SFTP; however, I want to be able to type in "projectx.local" in a browser on my laptop to go to one test site, "projectz.local" to go to another, etc.
Is this possible, since I do not have the server set up as my gateway? It is merely connected to the router like everything else.

View 8 Replies View RelatedWhilst I have used GUI-based Linux distros for the last few years, I am now struggling somewhat when it comes to setting up a server from the command line. All the howto's I've read so far tell you how to set up certain things, but I don't know what I actually need to set up.Rather than asking the same questions all over again on a forum like this, and generally being a bit of a noob, I wonder if there's a resource somewhere that someone could direct me to in order to know what I need to do to set up a fileserver.
The hardware is all done, and I will probably set up a router distro like IpCop to manage the network, but I'm rather lost as to what packages I need, and how to know what the server is/isn't doing.I've used plenty of command lines in the past (ms dos, amiga dos, BASIC programming etc), just not a linux command line.

View 9 Replies View RelatedI recently built a basic server computer for home use. (this will be for media, documents, music, etc) I have a basic amd mobo, cpu, and dvd drive. I have Ubuntu server 9.10 installed on an 8GB SD card that is attached to a usb dongle. The os loaded just fine And as a storage drive i have a seagate 1TB hard drive.
Then i got to creating shares in samba. I got to editing the smb.conf file and i couldn't figure out how to setup the shares (where exactly the 1tb Hard drive is, how to create directories and what not) Then i realized i needed to format the HDD! but when i go to run fdisk to finally do it, it tells me that it is "unable to open /dev/sda/"
Now i don't know a whole lot about linux as you can tell, but that is the whole reason i set this thing up is for a big learning experience in both linux and network setup.
To sum up, how do i format the 1TB HDD, and how would i set up samba so i could administrate it from my other computer (SWAT is what i've read about)
