Child Folder inheriting a permission that parent folder does not have (NTFS)

- by just.another.programmer

I'm reconfiguring roaming profiles on my network to use proper NTFS security settings according to this article. I have reset the following permissions on the roaming profile parent folder: CREATOR OWNER, Full Control, Subfolder and files only User group with profiles, List folder, Create folders, This folder only System, Full Control, This folder, subfolders, and files Then I select one of the actual roaming profile folders and follow these steps to fix the NTFS settings: Click Security, Advanced Uncheck "Allow inheritable permissions..." Choose "Remove..." Recheck "Allow inheritable permissions..." Click "Apply" After I choose apply, I get the following permissions listed on the roaming profile folder: Administrators (MYDOMAIN\Administrators) Full Control, This folder only CREATOR OWNER, Full Control, Subfolders and files only System, Full Control, This folder, subfolders, and files Where is the Administrators entry coming from!? There is an entry on the root of the drive for Administrators to have full control, but the Roaming Profile Parent folder is not set to inherit any permissions, and it does not have the administrators permission.

On a Mac, how are connections (possibly by spyware) made to outside internet addresses during initia

- by TT

I am trying to secure a Mac after discovering that network links are being established to some unwanted internet sites. Using 'lsof -i' (list open 'files', internet) I have seen that launchd, ntpd, firefox, dropbox and other processes are either 'LISTENING' or have 'ESTABLISHED' links to a site or sites which I suspect have to do with spyware. I have been trying to find startup files and preference lists that initiate thise links but can't find them. I could easily reinstall the OS and restore data from a backup but I'd prefer to know how to fix this as I have six Macs to look after. Thanks...

Test disk recovery

- by AIB

I had a 250GB hard disk having several NTFS partitions. The disk was a dynamic disk (created in windows). Now when I formatted windows (which was in another disk), the dynamic disk is shown as offline. I tried using the testdisk tool to recover the data and created a partial backup. Testdisk is able to list all partitions in the disk. All partitions are shown as type 'D' (Deleted). I want to change the 'D' to 'P' (Primary), 'L'(Logical), 'E' (Extended) appropriately and build a new partition table. If I can write the partition table to disk, the disk will be of 'basic' type and should be readable in all OS. What should be the appropriate partition types? I checked the files on the partitions and no OS was ound. So none of the partitions were bootable. Will randomly selecting P,L,E hurt the data in anyway?

Debian Squeeze locale settings

- by regularfry

I have a problem with a slightly customised Debian image that I'm trying to do some headless work on. The problem is that the installed locales list has been reduced to this: C en_GB en_GB.iso88591 en_GB.iso885915 en_GB.utf8 POSIX However, when I log in as root (with an otherwise as-vanilla profile), I find this: ~# set | grep LC_ LC_CTYPE=en_US.UTF-8 That's the only LC_ environment variable set, and presumably that means that it's being explicitly set somewhere (and given that /etc/default/locale only contains LANG=en_GB, I can't see any other alternative). However, I can't see where it is being set, and the fact that it's wrong is preventing, for example, postgresql-8.4 from installing. I know I can do an LC_CTYPE=en_GB apt-get install postgresql-8.4 to work around this, but I'd really like to understand where this setting comes from, and I really dislike the idea of installing an otherwise-unnecessary locale to make this go away. So: where does this LC_CTYPE setting come from, and how do I make it go away?

Intermittent connection issues with atheros ar9285

- by MrStatic

I have an asus K50IJ which has an atheros ar9285 wifi chip. It has decided to start to randomly drop internet. Although the card doesn't seem to notice it has. It will show full signal instead of say 3 bars. I tried to look at the atheros site for the latest driver but they don't even offer driver downloads. I then checked the asus site and it doesn't even list that card in the downloads for this laptop. I run Windows 7 64bit. It will drop either every minute or once a day while I am doing intensive bandwidth usage and when I am just idling.

deleting old unused images

- by Ayyash

As we move on with our content-based websites, lots of images get dumped in our images folder, but we rarely come across self-committed monkyes that delete their files once they do not need it, which means, we end up with a huge list of images in one folder, and it is very tricky to clean it up. My question is (and i dont know if this is the right website to ask it), is there a tool that allows me to find out if an image has been requested by web in the last (n) months? my other general question is, how do you do it? how do you take control of your images folders? what policy do you enforce on developers to clean up? what measures do you take in order to decide what goes and what stays if you end up with an out-of-control situation? my suggestion was to rename the images folder, create a new one, copy the basic ones and wait for someone to complain about a broken image! :) i find this to be the most efficient.

Consequences of changing a password in Windows

- by Borek

I'm having 2 machines on my home network where I have the same account name but different passwords. I believe there should be advantages to having a single one (I hope :) but also think that changing it on one of the machines will do something - I'm just not sure what exactly. Will my stored passwords in IE and Chrome still work? Scheduled tasks? Etc. I'm looking for a list of things that I should watch out for after I change the user password.

shutdown -i all computers in active directory domain

- by Sihan Zheng

I'm not sure if this is possible, but this is my goal: At the end of the day, I want to be able to turn off all the computers in the domain from a client. My account has sufficient privileges to shutdown any single computer remotely using shutdown -I, and I can RDP into any computer in the domain. However, is there an automated technique that does this? the computers in the domain are predictably named (computer1, computer2, etc), but than manipulating a list of 2000 computers in shutdown -I is pretty clumsy. Is there a way to shutdown every single computer in the domain from a single client? The domain server is windows 2003, and the clients all run windows xp thanks

Downtime scheduling - can it be automated?

- by Nnn

When servers need to have scheduled downtime at my workplace we follow a process roughly like the following: Propose time for work to take place on specific box/s Lookup list of stakeholders for specific box/s Seek approval from stakeholders (service owners/management etc) via email Incorporate changes to proposed time if necessary, repeat step 2 until.. Now everyone is happy with the time, send out a notification via email of the time, ask Staff who care about when the box is going down manually add it to their calendars some stakeholders the staff doing the work Do the actual work Is there an OSS project that we could use to automate this process? My googling has been fruitless so far. Will we need to build something ourselves? Would anyone else be interested in something like this?

Huge email sizes when using mail merge in Word 2010

- by Nic

So I've designed an HTML template to send out some emails on. The code is fine, everything looks great there, and it tests just fantastically. I was sending out putting my recipients in the BCC field, but I decided to make it a little more personal and open the file in Word and do an email merge. The HTML file itself is 3.06kb and contains an img src to an absolute URL, which is about 125kb (a little large, I know, but it's very important). When I merge the file from Word 2010 - Outlook 2010, the email size jumps to about 250kb. It's not much, I know, but I'm a gigantic nerd and I'm stuck thinking it should be about 5kb with MIME overhead. Here's the file list on one of the test emails: File Size image001.png 104366 image002.gif 43 MESSAGE 1259 Mime.822 152575 TEXT.htm 5712 Since the img src is specified, I'm not sure why these are coming through. If this is an issue inherent to Outlook, I'd be happy to explore other options.

Mysterious winamp ratings that come from nowhere

- by Phenom

Winamp gives the option to rate songs. This is not a new feature. Everytime I would reinstall Windows and reinstall Winamp my ratings would all go away as expected, and I would have to re-rate everything. However, this time when I reinstalled Winamp, after using it for a few days, songs would appear in my top rated list as being rated. Some of these I remember rating a long time ago before I reinstalled Windows, and some of these I don't remember ever rating. Where are these ratings coming from?

Creating Persistent Drive Labels With UDEV Using /dev/disk/by-path

- by Matt

I have a new BackBlaze Pod (BackBlaze Pod 2.0). It has 45 3TB drives and they when I first set it up they were labeled /dev/sda through /dev/sdz and /dev/sdaa through /dev/sdas. I used mdadm to setup three really big 15 drive RAID6 arrays. However, since first setup a few weeks ago I had a couple of the hard drives fail on me. I've replaced them but now the arrays are complaining because they can't find the missing drives. When I list the the disks... ls -l /dev/sd* I see that /dev/sda /dev/sdf /dev/sdk /dev/sdp no longer appear and now there are 4 new ones... /dev/sdau /dev/sdav /dev/sdaw /dev/sdax I also just found that I can do this... ls -l /dev/disk/by-path/ total 0 lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-0:0:0:0 -> ../../sdau lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:1:0:0 -> ../../sdb lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:2:0:0 -> ../../sdc lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:3:0:0 -> ../../sdd lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-0:4:0:0 -> ../../sde lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-2:0:0:0 -> ../../sdae lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:1:0:0 -> ../../sdg lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:2:0:0 -> ../../sdh lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:3:0:0 -> ../../sdi lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-2:4:0:0 -> ../../sdj lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:02:04.0-scsi-3:0:0:0 -> ../../sdav lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:1:0:0 -> ../../sdl lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:2:0:0 -> ../../sdm lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:3:0:0 -> ../../sdn lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:02:04.0-scsi-3:4:0:0 -> ../../sdo lrwxrwxrwx 1 root root 10 Sep 19 18:08 pci-0000:04:04.0-scsi-0:0:0:0 -> ../../sdax lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:1:0:0 -> ../../sdq lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:2:0:0 -> ../../sdr lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:3:0:0 -> ../../sds lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-0:4:0:0 -> ../../sdt lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:0:0:0 -> ../../sdu lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:1:0:0 -> ../../sdv lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:2:0:0 -> ../../sdw lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:3:0:0 -> ../../sdx lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-2:4:0:0 -> ../../sdy lrwxrwxrwx 1 root root 9 Sep 19 18:08 pci-0000:04:04.0-scsi-3:0:0:0 -> ../../sdz I didn't list them all....you can see the problem above. They're sorted by scsi id here but sda is missing...replaced by sdau...etc... So obviously the arrays are complaining. Is it possible to get Linux to reread the drive labels in the correct order or am I screwed? My initial design with 15 drive arrays is not ideal. With 3TB drives the rebuild times were taking 3 or 4 days....maybe more. I'm scrapping the whole design and I think I am going to go with 6 x 7 RAID5 disk arrays and 3 hot spares to make the arrays a bit easier to manage and shorten the rebuild times. But I'd like to clean up the drive labels so they aren't out of order. I haven't figured out how to do this yet. Does anyone know how to get this straightened out? Thanks, Matt

Log of cron actions on OS X

- by Doug Harris

Does the cron which comes with OS X log its actions anywhere? I'm not looking for output of any particular cron job, but rather log of what cron is doing. On a couple linux machines I've checked, there's /var/log/cron which has contents like: Apr 26 11:00:01 localhost crond[27755]: (root) CMD (/root/bin/mysql-backup) Apr 26 11:01:01 localhost crond[27892]: (root) CMD (run-parts /etc/cron.hourly) Apr 26 11:07:01 localhost crond[28138]: (root) CMD (/usr/local/bin/python /home/ user1/scripts/pythonscript.py) Apr 26 11:18:18 localhost crontab[28921]: (user2) LIST (user2) Apr 26 11:18:22 localhost crontab[28929]: (user2) BEGIN EDIT (user2) Apr 26 11:18:59 localhost crontab[28929]: (user2) REPLACE (user2) This shows when jobs ran, when users viewed or edited crontabs, etc. This stuff is nowhere that I've found on my Snow Leopard machine.

Subversion problem, repo has moved

- by Rudiger

Hi, I've set up subversion on a CentOS fresh install. Web view works fine and gives no errors and requests password but when I try and access it through svn client (xcode) it gives the error 175011 (Repository has been moved). I've tried some of the solutions out there but no success. My subversion.conf: <Location /repos> DAV svn SVNParentPath /var/www/html/repos # Limit write permission to list of valid users. # Require SSL connection for password protection. SSLRequireSSL AuthType Basic AuthName "Authorization Realm" AuthUserFile /etc/svn-auth-conf Require valid-user </Location> My Apache DocumentRoot: /var/www/html I've only set up one svn repository so far so there shouldn't be any conflicts there. If you need any more info let me know. Thanks

Are there any good apps for managing vCard vcf files?

- by Lunatik

I've just got an Android handset and the import of the SIM contacts from my old phone has left them in a mess; lack of capitalisation, funny character substitutions, odd delimiters etc. I have exported the contacts list as a vcf and while I could manually edit this file, I was really after a desktop app that could do formatting, search & replace etc. There are Android apps that do this but, as much as I like the phone's UI, the prospect of sorting hundreds of contacts via it doesn't exactly fill me with joy. A quick Google just threw up lots of questionable download sites, hoping someone can suggest a lightweight alternative

Getting back the old alt-tab windows switching behavior in Windows 7?

- by Carlos A. Ibarra

When you run more than 6 applications on Windows 7 and you press alt-TAB, icons representing the first 6 applications and the desktop appear on the first row of the grid and you can cycle with alt-TAB-TAB... through the 6 most recently used windows the usual way, but the 7th and other less recently used windows don't follow the same rules. Instead they get grouped together according to their application but disregarding whether they were recently used or not. This new behavior is mentioned here. I am very used to the old way of cycling and the new system is driving me crazy. I tend to have 20 or so windows open at one time and I frequently need to alt-tab to the 7th or 8th window on the stack but it doesn't work the same anymore. Does anyone know how to put back the old behavior, so that alt-tab-tab-tab... goes through the whole list in most-recent to least-recent order?

What resources are best for staying current about information security?

- by dr.pooter

What types of sites do you visit, on a regular basis, to stay current on information security issues? Some examples from my list include: http://isc.sans.org/ http://www.kaspersky.com/viruswatch3 http://www.schneier.com/blog/ http://blog.fireeye.com/research/ As well as following the security heavyweights on twitter. I'm curious to hear what resources you recommend for daily monitoring. Anything specific to particular operating systems or other software. Are mailing lists still considered valuable. My goal would be to trim the cruft of all the things I'm currently subscribed to and focus on the essentials.

Editing sudoers file to restrict a user's commands

- by devin

Is it possible to edit the sudoers file so a user can use sudo for any command except for a specified one? I reverse is true, I believe, that the sudoers file can be setup so that a user can only execute a given list of commands. EDIT: the commands I really want to take away are halt and reboot... this makes me think there are special system calls for halt and reboot. Can you take system calls away from a user? If not, is it because the unix permission system abstracts over system calls neglecting this?

Running mysqlimport on a MyISAM table for hours, Data_length stays at 0

- by Yuriy

I'm trying to import a fairly large file (5Gb, ~130M records) into a MyISAM table (mysql 5.1.61). It's been running for more than 5 hours now with no errors displayed, and I can see "LOAD DATA INFILE ..." in the process list. However, when I run SHOW TABLE STATUS, "Data_length" for the table being updated is still 0. I wonder if that's normal - if not, I should probably abort the import to see what's wrong. "Update_time" displayed by SHOW TABLE STATUS is up-to-date and changes quickly. Is it normal for "Data_length" to remain zero while mysqlimport is successfully running?

Difference between *:80 and _default_:80 in Apache2

- by Johannes Ernst

I'm trying to understand the difference between the following two terms: *:80 _default_:80 in the Apache configuration file. The documentation here is unclear to me, and the only mailing list conversation that I could find here does not shed any (comprehensible, to me) light on the matter either. I have a bunch of name-based virtual hosts declared like this: <VirtualHost *:80> ServerName example.com ... and I'd like to have an entry that fires when none of those match, i.e. when a request comes in without a virtual host name, or with a virtual host name that has not been declared. Should I use *:80 or default:80?

Reminders about unresponded emails?

- by ulidtko

In my daily e-mail often happens the following scenario: I send somebody an email which describes some problem and requests an action from the recipient. Typically, I wish to ensure that this action was taken, or at least somehow resolved; when this happens, the email recipient should notify me with a response email about what was done, and what was not and why. But, sometimes emails don't get read by the recipient, or he forgets to reply to me. At the same time, I cannot constantly keep in memory the list of all emails for which I was waiting an answer and still didn't receive it. So I wonder, is there in any email client such a feature which would allow me to somehow mark specific outgoing emails as "demanding reply"? The mail client could in this case notify me if any "demanding reply" emails still aren't replied for a long time.
