View 1 Replies View RelatedIn my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
I purchased an older Dell (p4 1.8G 256M) just to run some low demand programs. They don't require a GUI - just ssh/cli type of access. will be a server type - no kb or monitor. Can someone give me some pointers where to start at? I've never done a Debian install - the install process may address these questions - but figured I would throw it out here. I've used Ubuntu for several years now but I doubt that it would be the best distro for a legacy system....
View 3 Replies View RelatedI know there are ways to change the login of a linux box (runlevel 3) so that you don't see the regular login prompt but that you get a list with options. You see this with appliances.
My goal is to create a login like some of those appliances have. Instead of just getting a login prompt you can select several options like login, change network configuration, change password, stuff like that. How can I do this? Is there an Open Source tool to configure this?
I have downloaded and setup the SUSE Lifecycle Management Server on vmware using the Live CD Distribution. I have connected it to Susestudio.com as my repository and setup a user account via the backend on pg 96 using the slms-admin-ui-user -o to create my administrator account since I lost the password for the initial login. I created a customer and have the following:
Mirroring Credentials - User Name: (random character)
Mirroring Credentials - Password: (random character)
Also I have a test box for installing the Live CD of our application. Do all appliance created on suse studio have the client to connect to the SLMS server or do need to install a client? If there is no client how do I obtain and add it to the appliance on susestudio.com ? How do I setup appliance as a client?
I am kinda stuck while providing solution for the above problem. I have achieved the fail over using keepalived but not sure how can we replicate the data from one server to other seamlessly and have them in sync with each other. My prime requirement for this project is end user should not notice the fail over and replicated copy of data should be available on the secondary as well.
View 3 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?
I have some .loc files from geocaching's website. I wrote a special script that takes these files and converts them to my Bushnell GPS format and moves them into the correct folder. Now I'd like to associate a double click with my script. However, the .loc file shows up as "XML Document". yes, it's an XML document, but I only want .loc XML documents to be executed by my script. How can I give .loc files their own "type" so I can give them their own "Open With" application and not mess up every other xml file?

Using gnome terminal (Ubuntu 10.10), is there a way to execute the default application associated to a file type, only by typing its name, as it is possible with Windows ?
For example, say I create a mime type associated to every file with the pattern *.abc. Lets say I associate this file type to application 'my_app'.
If I have file 'my_file.abc' in current folder, what I want is that when I enter only 'my_file.abc' at the prompt, it executes 'my_app' feeding it with 'my_file.abc' as first argument. (assuming of course 'my_app' is in the path)

View 2 Replies View RelatedI'm trying to replace an office file server. I would like to avoid just another samba share.
I'm looking for a document repository, a bit more functionality than a plain samba share and very cross-platform.
I've looked a couple minutes at dspace, but that seems like a lot of work just configuring it. Dropbox would be fine except that they only have up to 100g, and it's off-site.
This is NOT for unauthenticated public use.
Here are some features I have in mind:
1. Web front end.
2. Any file format from a one-line text document to a Microsoft Word document to an ISO of a blu-ray disk to a very large database backup, binary or text.
3. Cross-platform clients, mostly Mac.
4. Authenticated via centralized one-login server or maybe by a key such as an SSH public key.
5. Searchable by terms, name or content if the type is appropriate.
6. Pass in the URL for an object and have the server download it.
7. Stores files in native format so if the app breaks I can just get the files.

View 1 Replies View RelatedI will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I am trying to make an application server that would contain simple ones like edit, openoffice, gimp, so on and so forth. I know how to access these using ssh but what I want is that the application runs on that server as it already does, but to open local files and save them locally.

We recently shifted our applcation and database to LINUX from UNIX.so now application server(weblogic 8.1) is on linux and oracle database 9i is on linux.previously there is a process in application server(which access the Database dor the data) which took only 1 hour to run on UNIX after shifting to LINUX the same process is taking 4 to 5 hours to run.
but when individually ran the queries on the database it is quck than UNIX.our ADMIN tried changing the kernel parameters for the database server, but it is still the same.
