  • Security: Unable to display current owner

    - by Jim McKeeth
    I have a user with local administrative rights on their Windows 7 64-bit box. They extracted a file from a zip file they downloaded with the Zip shell extension to their desktop on a non-encrypted or compressed NTFS volume. Unfortunately they cannot open it. I tried to take ownership of it and it just reports "Access is Denied" and for the current owner it reports "Unable to display current owner." At this point the file cannot be deleted, executed or modified. I have actually seen this exact same happen in Vista before, but I can't for the life of me remember how to fix it. Any ideas how it happened or how to fix it? I'd be happy just to delete it without a format at this point.

  • Removing a device in "removed" state from Linux software RAID array

    - by Sahasranaman MS
    My workstation has two disks(/dev/sd[ab]), both with similar partitioning. /dev/sdb failed, and cat /proc/mdstat stopped showing the second sdb partition. I ran mdadm --fail and mdadm --remove for all partitions from the failed disk on the arrays that use them, although all such commands failed with mdadm: set device faulty failed for /dev/sdb2: No such device mdadm: hot remove failed for /dev/sdb2: No such device or address Then I hot swapped the failed disk, partitioned the new disk and added the partitions to the respective arrays. All arrays got rebuilt properly except one, because in /dev/md2, the failed disk doesn't seem to have been removed from the array properly. Because of this, the new partition keeps getting added as a spare to the partition, and its status remains degraded. Here's what mdadm --detail /dev/md2 shows: [root@ldmohanr ~]# mdadm --detail /dev/md2 /dev/md2: Version : 1.1 Creation Time : Tue Dec 27 22:55:14 2011 Raid Level : raid1 Array Size : 52427708 (50.00 GiB 53.69 GB) Used Dev Size : 52427708 (50.00 GiB 53.69 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Intent Bitmap : Internal Update Time : Fri Nov 23 14:59:56 2012 State : active, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 Name : ldmohanr.net:2 (local to host ldmohanr.net) UUID : 4483f95d:e485207a:b43c9af2:c37c6df1 Events : 5912611 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 0 0 1 removed 2 8 18 - spare /dev/sdb2 To remove a disk, mdadm needs a device filename, which was /dev/sdb2 originally, but that no longer refers to device number 1. I need help with removing device number 1 with 'removed' status and making /dev/sdb2 active.

  • tools to check password security

    - by tombull89
    Hello again. I'm after a tool to test how long a password could stand up to a hacking/cracking technique such as brute force as two passwords that are critical to a work system is one word that is in the dictionary, and another is a word in the dictionary with a capital letter and a number instead of a letter. I'd prefer it to be offline and free that you can run on a computer to see how long the password will hold out. Maybe even at the windows login prompt but I realise such programmes may be shady and erring on the side of illegal. Anybody have any suggestions?

  • Security Restrictions Downloading From the Internet

    - by Cyper
    Hi, For some reason since we rolled out IE7 to the estate users are unable to download from the Internet, they get an error message "the operation could not be completed due to restrictions on the computer" I have checked the GPO and it allows downloads in the Default domain policy. I am I missing something in GPO or is this problem with IE7. Any help would be much appreciated. Cheers

  • windows 2008 R2 TS printer security - can't take owership

    - by Ian
    I have a Windows 2008 R2 server with Terminal server role installed. I'm seeing a problem with an ordinary user who is member of local printer operators group on the server. If the user opens a cmd window using ‘run as administrator’ they can run printmanager.msc without needing to enter their password again. In printmanager they can change the ownership of redirected (easy print) printers without problems. If, from the same cmd window, they use subinacl to try and change the onwership of the queue to themselves they get access denied: >subinacl.exe /printer "_#MyPrinter (2 redirected)" /setowner="MyDom\MyUsr" Elapsed Time: 00 00:00:00 Done: 1, Modified 0, Failed 1, Syntax errors 0 Last Done : _#MyPrinter (2 redirected) Last Failed: _#MyPrinter (2 redirected) - OpenPrinter Error : 5 Access denied so, same context, same action but one works and one doesn't. Any ideas for this odd behaviour? I'm using subinacl x86 on an x64 server as I can't find anything more up to date. I've tried with icacls and others but couldn't get them to do anything with printers.

  • Software raid 0 with six disks performance

    - by user134880
    I have some problems with disk performance. I have 6 x WD 500Gb RE4 disks. Each disk gives 135Mb/sec throughput. All measurements are made with hdparm with options "-tT" (I know that it is just synthetic test, but I need some start point to make measurements). I have controller with Sil3124 x 4 ports PCI Express 1x So... RAID0 on controller with 2 disks gives 200Mb/s - ok, pcie limit. RAID0 on motherboard with 2 disks gives 270Mb/s - niceeee :) RAID0 on contorller with 4 disks gives 200Mb/s - ok, pcie limit. RAID0 on controller with 4 disks + 1 disks on motherboard = 340Mb/s ... :( RAID0 on controller with 4 disks + 2 disks on motherboard = 300Mb/s .... why? Any ideas? Maybe need more cpu power? Now there is Pentium D Dual core 2.8Ghz, 4Gb RAM. It is dedicated box for storage.. no other activity.

  • Software to hold battery at 50% charge level

    - by Mehper C. Palavuzlar
    My Sony Vaio laptop has a built-in program called "Sony Battery Care" which provides a functionality to hold battery at certain levels of charge while operating. For example, I've set it to 50% and the battery is always kept at that level while on AC power. This mode prevents battery degradation and is more effective as I usually use my laptop with AC power. I'm looking for a similar program to use with other laptops with Windows OS; preferably a free one.

  • Apache Request IP Based Security

    - by connec
    I run an Apache server on my home system that I've made available over the internet as I'm not always at my home system. Naturally I don't want all my home server files public, so until now I've simply had: Order allow, deny Deny from all Allow from 127.0.0.1 in my core configuration and just Allow from all in the htaccess of any directories I wanted publicly viewable. However I've decided a better system would be to centralise all the access control and just require authentication (HTTP basic) for requests not to 127.0.0.1/localhost. Is this achievable with Apache/modules? If so how would I go about it? Cheers.

  • Installing a personal security certificate for Windows Server 2008 Terminal Services user

    - by Rick
    We use StoneEdge Order Manager, which runs under Microsoft Access, on several Windows computers as well as through Terminal Services on Windows Server 2008. Terminal Services users are unable to process credit cards using the First Data Global Gateway on the server. We have followed the necessary setup instructions provided under the user account, which involves adding a certificate in the Internet Options control panel. The Windows XP desktops require this to be done, or a generic 'unable to connect' message is shown when attempting to charge a card. On the server, this message is shown regardless of whether the certificate has been installed. Is there anything else that needs to be done that is specific to Windows Server that is not mentioned in the workstation instructions? Setup Instructions

  • Assembling Software RAID in Live CD for data recovery

    - by Maletor
    I need help recovering some data that's on my RAID which is on a LVM on my server running Ubuntu. What happened was I deleted the logical volume that controlled my swap space which was on a partition on drives sda2, sdb2, sdc2, and sdd2 in RAID1. This foobared my whole system for one reason or another. Booting leave me with grub rescue and an error saying that it is an unknown filesystem. When I boot to a live cd I can see my RAID arrays and I can even start them up. However, it doesn't appear to mount them anywhere so I can't see the data. I am in the live cd now and I have done sudo apt-get install mdadm lvm2 so it should be mounting them correctly. I just can't see why it wouldn't. Please any help is appreciated here. Here is some output. By the way, there are 3 RAIDs, 1) /boot 100mb RAID1, 2) swap 10gb RAID1, 3) root 990GB RAID5 ubuntu@ubuntu:~$ df -h Filesystem Size Used Avail Use% Mounted on aufs 124M 101M 18M 86% / none 2.0G 324K 2.0G 1% /dev /dev/sde1 2.0G 826M 1.2G 42% /cdrom /dev/loop0 667M 667M 0 100% /rofs none 2.0G 164K 2.0G 1% /dev/shm tmpfs 2.0G 28K 2.0G 1% /tmp none 2.0G 92K 2.0G 1% /var/run none 2.0G 0 2.0G 0% /var/lock none 2.0G 0 2.0G 0% /lib/init/rw /dev/md1 91M 73M 15M 84% /media/5ac3dbf1-a6c5-409c-96ae-edc6e27992c7 ubuntu@ubuntu:~$ cat /etc/fstab aufs / aufs rw 0 0 tmpfs /tmp tmpfs nosuid,nodev 0 0 /dev/sda2 swap swap defaults 0 0 /dev/sdb2 swap swap defaults 0 0 /dev/sdc2 swap swap defaults 0 0 /dev/sdd2 swap swap defaults 0 0

  • Virtualization software for windows 7

    - by user23950
    I've been using Shadow User and Deep freeze for windows xp. But I don't think its compatible with windows 7. Do you know of any application that can achieve the same thing? Please don't tell me to use Returnil virtual system because I've had a really bad experience with it when I'm using xp. The system just restarted over and over. And I have just reformatted by that time.

  • Backup software for Ubuntu - which one?

    - by Industrial
    Hi everybody, I have spent some time testing out different backup solutions for my small home office during the last weeks, but still haven't found anything that have been working out too well yet. We can definitely work with a non-GUI script if that's what it takes, if only the requirements are fulfilled: Upload to Amazon S3 Europe. We get unbelievable slow uploading speed to US, so uploading 400+ GB of data will not be happening anytime this year... Incremental backups - only changed files shall be uploaded or we will have a big bill from Amazon in the end of each month.. Files should not be uploaded in one big per-folder archive. This is not efficient at all, since if we change one file in a subfolder, a huge two-digit GB sized file would have to be uploaded during next backup. Not good for economy again, or traffic overhead on our internet connection. What options are available to us? Thanks!

  • domain screensaver control software

    - by Pec
    I'm looking to buy a screensaver control product with granular control. I have about 2000 workstations which require dozens of different timeout values, lock/not locked on resume settings, different screen saver files (that can be frequently updated depending on department), etc. It's looking to be quite an undertaking accomplishing this with domain group policies so I'm hoping you guys have some suggestions of products to use. Hopefully such products would integrate with AD. Thanks

  • How should I track approval workflow when users at every security level can create a request?

    - by Eric Belair
    I am writing a new application that allows users to enter requests. Once a request is entered, it must follow an approval workflow to be finally approved by a user the highest security level. So, let's say a user at Security Level 1 enters a request. This request must be approved by his superior - a user at Security Level 2. Once the Security Level 2 user approves it, it must be approved by a user at Security Level 3. Once the Security Level 3 user approves it, it is considered fully approved. However, users at any of the three Security Levels can enter requests. So, if a Security Level 3 user enters a request, it is automatically considered "fully approved". And, if a Security Level 2 user enters a request, it must only be approved by a Security Level 3 user. I'm currently storing each approval status in a Database Log Table, like so: STATUS_ID (PK) REQUEST_ID STATUS STATUS_DATE -------------- ------------- ---------------- ----------------------- 1 1 USER_SUBMIT 2012-09-01 00:00:00.000 2 1 APPROVED_LEVEL2 2012-09-01 01:00:00.000 3 1 APPROVED_LEVEL3 2012-09-01 02:00:00.000 4 2 USER_SUBMIT 2012-09-01 02:30:00.000 5 2 APPROVED_LEVEL2 2012-09-01 02:45:00.000 My question is, which is a better design: Record all three statuses for every request ...or... Record only the statuses needed according to the Security Level of the user submitting the request In Case 2, the data might look like this for two requests - one submitted by Security Level 2 User and another submitted by Security Level 3 user: STATUS_ID (PK) REQUEST_ID STATUS STATUS_DATE -------------- ------------- ---------------- ----------------------- 1 3 APPROVED_LEVEL2 2012-09-01 01:00:00.000 2 3 APPROVED_LEVEL3 2012-09-01 02:00:00.000 3 4 APPROVED_LEVEL3 2012-09-01 02:00:00.000

  • How does the PPA fit into the scenario of publishing an application to the Ubuntu Software Center?

    - by Mridang Agarwalla
    I've been going through docs for the past couple of hours but I haven't understood what the PPA is? I have a cross-platform Java application that I'd like to publish to the Ubuntu Software Center. My application is open-source and I'm using Github. Apparently, publishing applications to the store isn't as simple as uploading a deb package - am I right? I need to create an account on Launchpad and put all my code there. I don't intend to move from Git to Bzr merely for the sake of publishing to the app store but luckily, one is able to set up source-code mirroring from Github to Launchpad. Since my application is still very premature, it'll have updates fairly often. When I build my application on my machine, do I simply go my Ubuntu App Developer page and upload the new DEB package or do they build my application from source? What exactly is the PPA for? I don't think I'll need too many of the Launchpad features so I'd like to stick to Github if possible. (Publishing for Ubuntu really isn't trivial. I can see why there are so many developers out there who haven't published their applications to the Ubuntu Software Center. Publishing an Android applications has been the easiest so far.)

  • Differences between software testing processes and techniques?

    - by Aptos
    I get confused between these terms. For examples, should Unit testing be listed as a software testing process or technique? I think unit testing is a software testing technique. And how about Test driven development? Can you give me some examples for software testing processes and techniques? In my opinion, software testing process is a part of the software development life cycle. For example, if we use V-Model, the software testing process will be System test, Acceptance test, Integration Test... Thank you.

  • How is a "Software Developer" different from a "Software Consultant"? What makes a consultant?

    - by Kumar
    I have seen a lot of people claiming themselves to be a "software consultant". These consultants do what a normal software developer does, write code, estimate tasks, fix bugs and attend meetings etc. The only difference being the financials, consultants end up earning more. Then how is a software developer different from a "consultant"? In addition to the main question, I would like to know how can a software developer become a consultant? Are there any specific guidelines for a consultant? Do they need to amass certifications and write up research papers? Please do not confuse the software consultant with a management consultant. Software consultants I have seen are not managers.

  • Entry level security engineering positions

    - by Jake
    This is a question that has been bothering me for some time now. I have asked people and have always got mixed replies. It also has to do with how I will start my career. So here goes: Can an entry level software engineer directly get a job in a security engineering position? I am a graduate student in software engineering with a lot of course work in security as well, including web application, network and mobile security. I want to know if in the current industry, can an entry level engineer take the risk to prepare towards finding a security related position, or is it always necessary for a year or 2 development experience before one should think about finding a security position. Thank you.
