  • How to make mounted external drive writable over SFTP

    - by Brandon
    I have a user that I log in with over SFTP to my Ubuntu box. They have permission to write to the home directory of course. The external hard drive gets mounted to /media folder but I can't write to it over SFTP while logged in with that user. How would I set the permissions to allow me to write to the drive?

  • IIS, SSL, and Virtual Directories

    - by yodie
    I'm running a webserver on WS 2k3, IIS 6.0. Some of the content is on that server, but most is in a virtual directory linked to another server. Everything works (almost) fine when no SSL is used. However, when using SSL, I cannot access the files in the virtual directory. Instead I get a generic error 500. Any advice?

  • Web Search for a Hard Drive

    - by zecougar
    Here is the situation. Our organization has a fair amount of data in the form of documents, images, videos stored on a intranet server. We need to be able to expose these documents via some sort of search functionality on the intranet. Provide some mechanism to organize and tag the documents on hard disk. Ideally we'd also like to provide a unified search across documents on the google apps for business instance that we have. Any ideas on how to approach this problem ?

  • Efficient algorithm for Virtual Machine(VM) Consolidation in Cloud

    - by devansh dalal
    PROBLEM: We have N physical machines(PMs) each with ram Ri, cpu Ci and a set of currently scheduled VMs each with ram requirement ri and ci respectively Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram ri. A PM with no VMs is shut down to save power. Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations. My Approach: Brute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by First Fit Decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I used the links. http://dumas.ccsd.cnrs.fr/docs/00/72/52/15/PDF/Esnault.pdf http://hal.archives-ouvertes.fr/docs/00/72/38/56/PDF/RR-8032.pdf Would anyone please clarify the solution or suggest any new approach/resources for better performance. I am basically searching for the algorithms not the physical optimizations and I also know that many commercial organizations have provided these solution but I just wanted to know more the underlying algorithms. Thanks in advance.

  • Can't recover hard drive

    - by BreezyChick89
    My drive got corrupt after a thunderstorm. It used to be 1 partition of 2.5tb but now it shows 2 partitions. It's weird because 300gig free space is about how much it had before corrupting, but it was part of the first partition. I tried $ sudo resize2fs -f /dev/sdb1 Resizing the filesystem on /dev/sdb1 to 536870911 (4k) blocks. resize2fs: Can't read an block bitmap while trying to resize /dev/sdb1 Please run 'e2fsck -fy /dev/sdb1' to fix the filesystem after the aborted resize operation. sudo e2fsck -f /dev/sdb1 e2fsck 1.42 (29-Nov-2011) The filesystem size (according to the superblock) is 610471680 blocks The physical size of the device is 536870911 blocks Either the superblock or the partition table is likely to be corrupt! Abort? n .... Error reading block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes Force rewrite<y>? yes Error writing block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes ... A lot of these. I can't use e2fsck -y because the first question aborts if I say "y". If I put a weight on the 'y' key it fails because none of the errors were really fixed. I asked this question before and tried using gparted but gparted fails because the first thing it does is: e2fsck -f -y -v /dev/sdb1 giving the same error. The disk status says healthy. There are no bad blocks. This is very frustrating because I can see the data in testdisk and it looks like it's all there. I already bought another 2.5tb drive and made a clone using dd. The next step if I can't fix this is to wipe that drive and just move the data with testdisk, but it seems certain folders will copy infinitely until the drive is full because of symlinks or errors so it's also a difficult option. sudo fdisk -l Disk /dev/sdb: 2500.5 GB, 2500495958016 bytes 255 heads, 63 sectors/track, 304001 cylinders, total 4883781168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0005da5e Device Boot Start End Blocks Id System /dev/sdb1 * 2048 4294969342 2147483647+ 83 Linux sudo badblocks -b 4096 -n -o badfile /dev/sdb 610471680 536870911 badfile is empty I also tried changing the superblock with "fsck -b" but all of them are the same.

  • Mount a remote Linux hard drive as another Windows 7 partition during boot?

    - by zhuanyi
    I would like to mount a hard drive on a remote computer (running on CentOS 6) as a Windows drive so that I can install programs to that drive. The primary hard drive for my Windows machine (which is at home) is pretty small, I have a Linux server sitting in a remote data center with a much larger hard drive and allow me to install more stuff. I know most of you are going to say Samba, unfortunately the biggest problem for me in this case is that I can not mount Samba as a network share unless I start OpenVPN or SSH tunneling first, which is not good for my case because I will install some startup programs to the remote drive as well. Therefore, the remote drive has to be ready and work just like another drive BEFORE any of the startup programs start to load. Is that possible? My home PC has Windows 7 Professional 32 bit installed and the remote server is a Xen virtual server running on CentOS 6. I have admin/root permissions for both. Thanks a lot!

  • How to transfer a website hosted online to my Virtual Host

    - by user831740
    I'm doing some work on a webpage, meaning I gotta modify a few things. As a result of this I installed apache and all the things that come associated with it, and also installed Joomla, and I got everything running well. My problem is, I need to make apache run this website locally, so I downloaded the public_html folder from the FTP server on my website, but I have absolutely no idea how to implement the website in order to make it run on apache. I've read a few guides, but they all tell me how to create a new website instead of helping me host a website already done.

  • Installed 11.10 on shared drive, when other partition mounted, HDD shown full

    - by Thebetpet
    I just partitioned a 500GB HDD 50%-50%. I installed ubuntu 11.10 on one half and copied a load of files onto the other. When I don't mount the other partition, it shows I have used 12.1GB and have about 240GB free. The second I mount the other partition, I can't copy any files over and get a disk full message. There is about 10-20GB Free on the other partition. Am I doing something wrong or is this a bug?
