• Using multiple USB webcams in Linux

  - by rachelderp

  Running more than one USB webcam in Debian/Linux results in the the following error: libv4l2: error turning on stream: No space left on device VIDIOC_STREAMON: No space left on device What initially seemed to be a programming issue in OpenCV turned into a quest for a mysterious hardware/software problem after the same errors were produced by running cheese and xawtv. Apparently it's caused by webcams requesting all the available bandwidth on the USB host controller. With that in mind I decided to run wireshark and capinfos to see just how much bandwidth a single camera used. 4 megabits per second at 320x240 14 megabits per second at 640x480 32 megabits per second at 1920x1080 Interesting! That might explain why two cameras at 320x240 work but any higher resolution fails. It's as if my USB controller is only operating at USB 1 speeds, yet lsusb shows both webcams belonging to a device which supposedly supports 480 megabits per second. One solution proposed forcing the webcams to calculate their bandwidth usage instead of requesting their maximum by running the following commands: sudo rmmod uvcvideo sudo modprobe uvcvideo quirks=128 Unfortunately that made no difference, so I decided to try another solution. A post on StackOverflow suggested telling my webcams to use a lower FPS or compressed video format like MJPEG, but after running v4lctl list it doesn't appear either of my webcams support changing their video mode. And that's where I'm stuck. Why would two webcams operating well below the maximum speed of USB 2 would produce this error? ps: It's not a disk space issue, df displays no change when the webcams are started. pps: If it makes a difference, here's the output of lsusb

• Strange Domain name under the same IP Address

  - by Mike Chip

  There's something really weird happening in my server. But first things first: I wanted to have my website and chose the domain name "myowndomain.com", Now on my domain registrar I point "myowndomain.com" to the address of my recently setup VPS, let's say 50.50.50.50 So I installed everything I needed to run my website, and I started to notice strange queries coming from different IP Addresses. Like these [client 123.123.123.123] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php [client 456.456.456.456] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php or like this (Really a long line, I cut some things) GET /?s=vod-show-id-22-area-%E5%85%B6%E4%BB%96-language-%E9%9F%A9%E8%AF%AD.html HTTP/1.1" 301 295 "http://v.strangedomain.com/?s=vod-s ...[cut]... spider" That above is happening the most. The 'strangedomain.com' returns the same IP address of my VPS which my website is hosted on. The whois of such domain shows it's registered to a chinese. But the street name didn't look so right (like a huge single word), so I think all of that info might be fake, but still might be a chinese. I also noticed that all 'clients' trying to access the 'strangedomain.com' is coming from china. If I type in the browser 'strangedomain.com', I see my website. I'm worried, because my website is actually an e-commerce. I don't know if 'strangedomain.com' WAS a website on 50.50.50.50 in the not so far past, or if it's something else.

• How can I extract data from Toshiba Satellite with a dead Windows installation?

  - by msanford

  I've got a Toshiba Satellite (unknown model number but bought early 2010) running Windows Vista which throws a kernel error on boot. We don't have the restore/recovery CD any more to restore the Windows partition. I have managed to boot to a Live CD version of Ubuntu 10.10 and have mounted the internal hard drive (which takes nearly 8 minutes). I suspect that the hard drive is malfunctioning, however, because copy tasks of even 30 megs of data to an attached and mounted USB flash drive takes over an hour, and some files are mysteriously inaccessible (not a permissions issue). When browsing folders, it takes many minutes to populate the folder window even with a single tiny file. During the copy tasks, the hard disk sounds like it tries to sleep several times in rapid succession, then continues accessing, it sounds, at full throughput. I initially tried using scp (from the shell) to copy data but I encountered the same local problems. I don't know the S.M.A.R.T. status of the hard disk, either. Is there a more effective way of going about recovering the data on the internal disk, assuming that I can't use a recovery CD and am too cheap to bring it in (for now, at least)?

• Why does my router log crazy amounts of blocked traffic on port 1701?

  - by Vlad Seghete

  I have a 2701HGV-B 2Wire modem and router (AT&T). The log is basically full with entries similar to the following with a time between a fifth and a third of a second between entries: src=86.156.7.170 dst=xxx.xxx.xxx.38 ipprot=17 sport=6882 dport=1701 Unknown inbound session stopped src=58.176.22.252 dst=xxx.xxx.xxx.38 ipprot=17 sport=21573 dport=1701 Unknown inbound session stopped src=91.221.6.250 dst=xxx.xxx.xxx.38 ipprot=17 sport=25902 dport=1701 Unknown inbound session stopped ... where the source IP will be different for every entry. The entries accumulate constantly, every single second that the router is on several of them appear in the log. The destination is the WAN address for my router. I understand that this is somehow related to VNCs, but I don't know enough to figure out why my router is getting bombarded with requests for a VNC session. Is there anything fishy going on or is this normal? If it is normal, how do I keep these entries from spamming my log files? Since there's about two or three of them every second, everything else gets drowned out.

• Copy a harddrive from a failed desktop machine using a second working one.

  - by MrEyes

  Heres the scenario: I have PC-A, an old PC that runs Windows XP but now refuses to boot due to a failed motherboard (or maybe PSU). This PC has a single 80gb IDE drive. I also have PC-B, running Windows Vista, this is working fine. I want to copy all the data off PC-As HDD onto PC-B. To do this I have taken the HDD out of PC-A and connected it as a slave to PC-B. PC-B now boots and sees the additional drive. However, when I attempt to access/copy user folders (i.e. Documents and Settings/[username]/*) I am told that I cannot access the folders due to user permissions. I am doing this under an adminstrator account on PC-B. So the question is, how can I "backup" the data? Preferably without making any changes to the drive contents. The reason for this is that it is possible that PC-A is failing due to a bad PSU, so I intend to replace it before writing off the machine. However I would feel much happier if I had a backup of the data on the HDD.

• How can I import tasks into Project that have already been started?

  - by unknown

  I am writing a feature to import tasks from an online bug tracking / project management tool into Microsoft Project, primarily for resource leveling. Currently I am importing all tasks in as Fixed work, and giving them an assignment to a single resource for 100% of the work. The duration is then dynamically calculated, which at import time is equal to the amount of work. However, I am not a project manager by any means, and am having difficulty on how to get the start dates to calculate correctly. I've never used Project either. I am using Schedule From Start and setting the Project Start Date to the date the contract was signed / work was approved. However, this can be in the past, and I do not want current tasks scheduled from that date. Should it be today then? Another problem I have is with tasks that were already started. I have remaining work set, and I was placing a constraint on them to be started on the day the work was first applied. However, the remaining work for the task would be scheduled from that date, which was sometimes in the past. Using task constraints, a project start date, and whatever other settings available to me that I don't know about, what is the correct way to have the tasks scheduled?

• How can I create a macro that acts on a relative reference rather than an absolute reference to cell A1?

  - by Bruce

  I have a master rent statement in an Excel 2007 (macro enabled) spreadsheet that shows all tenants in rows with columns formed by the months. Each tenant then has a separate rent statement sheet like the one below that pulls the data through from the master rent statement and all I do then is to copy the last 4 columns to the right and add them to the right, just renaming the month labelled as ‘rent due’ with the current month and then hiding the previous last 4 columns to the left so that the statement always shows the previous month's activity and the amount due for the current month: I used a macro to speed up the creation of these statements, but then found that in some cases the result was wrong and needed major correction because the macro use absolute references i.e. its starting position was relative to cell A1 whereas some of my rent worksheets commence from a different column and in some cases from a different column and a different row. I have tried recording the macro with 'Use relative references' but when trying to use the macro it only gets part way through its operation before it stops and the message appears: Run time error '1004' Application defined or object defined error with the option to End or Debug or go to Help and then I'm stuck as I don't know how to debug and work in VBA or understand what has gone wrong. I want to record a single macro that always remains relative to the last 'Total Due' column heading (in the sample, it’s cell FF3 but on another worksheet could be cell GA26) and thus enables me regardless of where on the worksheet the rent statement is placed to add through my recorded macro a further four columns with updated dates and a repositioned 'Total Due' summary (in the sample in cells FE23 and FF23). The contents of cells FE23 and FE22 are always the same number of rows from the 'Sample Rent Statement, Service Charge and Sub Total' rows. I've searched on the web and in the help files of Excel 2007 but have been totally stumped by this, so currently I have to re-record a quantity of macros each month to cover all of the permutations of the worksheets in my Excel rent workbook, which is starting to become pointless in terms of saving time. Does someone know a solution to this problem please?!

• What other ways can I load balance EC2 servers without using Elastic Load Balancing?

  - by undefined

  I have a web application that consists of a web server managed by a web hosting firm, a set of EC2 instances in amazons cloud and a MySQL database (hosted on the webserver). MySQL is behind a firewall and is set to allow access from Localhost and from a single IP address which is an Amazon Elastic IP address that is attached to the EC2 instance I have been running up to now. The problem is that I want to look at my scaling up and load balancing strategy for my EC2 instance. To this end I have been investigating the Elastic Load Balancers and Autoscaling tools that Amazon provides and have managed to set this up fine but for one thing - connecting to the MySQL database running on my webserver. I realised (thanks to answers on Serverfault) that I needed to check firewall settings and add the IP address for the load balancer, however Elastic Load Balancers provide you with a DNS name, not an IP address and infact the IP addresses change over time so this will not work. I have been told by the company hosting the database that the way the firewall works is to look up the IP address of the DNS name and store the IP rather than the DNS name. so basically this will not work and the only way to allow access would be to open up the SQL port to allow access from anyone! Is this a viable idea? Should I look at moving my database into the cloud? Is there another firewall that the server company can use? Should I find another way of load balancing (if so what?) tricky one eh? any help appreciated!

• Expand a volume residing on one X-RAID disk installed on a Netgear ReadyNas Duo v2

  - by Sid

  I've got a Netgear ReadyNas Duo v2 (2 disk slots). System is configured with X-RAID which does not provide flexibility but automatically expands based on a sort of RAID-5 logic. I had 2 500 GB hard disk installed, redundant, so I had 500 GB of volume size. I wanted to upgrade the whole system to 3 GB * 2 hard disk maintaining both the data already on the NAS and the data on one of the two 3 TB hard disks. So I did this: Unplugged one disk from the ReadyNas. Now the readynas has 1*500 GB non redundant. Plugged one empty 3 TB hard disk. Now the readynas has 1*500 GB + 1*3 TB, redundant. I waited for the resync. I then unplugged the 500 GB hard disk, so that I have only the 3 TB hard disk with the previous data. Now what I want is to copy the data on my other 3 TB hard disk in the NAS, so that I can plug this other disk in the NAS and use it for redundancy. The problem is that: the NAS has the (single) 3 TB hard disk in X-RAID, but the volume does not expand to 3 TB, it remains fixed to 500 GB. Is there a way to tell the ReadyNas to force expanding the volume to the whole disk without plugging in another hard disk of the same size?

• Install Peppermint OS three on Asus EeePC

  - by Kithoth

  I just had a new Asus EeePC R051CX. Out of the box, the installed OS is Ubuntu 12.04 LTS, but I am trying to install Peppermint OS three (as single boot). Problem. Once on live CD (well, live USB stick...), I'm in trouble in both following situations: Try Peppermint OS Live In this case, the first thing I get is a message reading The system is running in low-graphics mode Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself. I can solely press "return" to accept, then I have a list of 4 options to answer the question "What would you like to do?". But I simply can't do anything at this moment, except switching to console mode or rebooting (keyboard / mouse controls don't allow me to do anything else). Install Peppermint OS Something I really don't understand... it launches the Ubuntu Recovery Media (which was already installed when I received the device)! Also, it says in the bottom ERROR: This recovery media only functions on Ubuntu systems. All I can do is quit (that is, reboot). One last important thing that comes to my mind: this stick worked just fine on the other computers I've tried it on. I really hope someone could bring me the light, a friend of mine told me how cool this OS is for EeePCs. Don't want to give up! Thanks. Edit I finally could install Peppermint, but not by understanding why I couldn't do it the logical way. Instead, I reinstalled Ubuntu myself (erasing the factory one). Then, I could simply boot on my live USB and perform a fresh install of Peppermint. So, I still don't know how and why the mentioned problem occurred.

• 3 Monitor PCI-e Graphics card (without tremendous pain)?

  - by N Rahl

  As we are all painfully aware, the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time. The exact message is: The current settings cannot be applied. Possible issues may include: - Display(s) cannot be enabled. - Setting(s) cannot be applied due to insufficient video memory. So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question: First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment.

• Can a VM perform better when only two cores instead of four cores are presented to it?

  - by arcain

  We had a VMWare VM at work with two cores allocated to it that ran a pretty heinous process in IIS. Under load the process was maxing out the CPU usage on both cores, so we asked our system engineers to present the other two cores of the physical processor to the VM. The engineer immediately said that this would not improve performance at all, but would make the VM perform worse. That statement didn't make much sense to me, and I'm wondering how what the engineer said could be true. Are there actually cases where four cores presented to a VM would cause worse performance than two cores on the same physical hardware? Let's assume an ideal situation where there's only one VM on the host server, so nothing is being shared with other OS instances. I believe the physical server had a single quad core processor, and was most likely hosting multiple VMs. I don't really know what version of ESX was running on the host, nor do I know with certainty what the physical processor config was, but from within the VM I had access to, I saw two 3.33 GHz AMD processors. In the end, I never got to test the engineer's assertion out because (while we were trying to get the VM upgraded) we were able to optimize the process and reduce it's CPU consumption, and 2) we ended up migrating to a different VM on another ESX server which had four cores presented to it.

• System Issues and Major Malfuctions after Failed hibernation Exit

  - by Sarah Seguin

  I have a HP G71-340US that went into hibernation mode for a while and when I tried coming out of it, I got an error message: You're computer cannot come out if hibernation . Status: 0xc000009a Info: A fatal error occurred processing the restoration data. File: \hiberfil.sys Any information that was not saved before the computer went into hybernation will be lost enter=continue So I hit continue and it ran soooo super slow it. It was seriously crawling. Finally I gave up and turned it off manually (IE press and hold the button). It's been a week or two since then and EVERY SINGLE TIME I have tried to to do ANYTHING it takes forever. When I say forever, I literally mean takes 5-7 minutes to load the internet, then the page itself, then to click a link, so on so forth. Eventually everything just goes not responding and I have to give up (4-6 HOURS later). I also cannot access my thumb/jump drives once I've managed to load windows. I was going to try runing malware bytes incase of a virus, but it's windows explorer developes errors and goes not responding on me. Currently I'm running scan disk or check disk and like every file is coming back unreadable. I let it run the last 2 hours straight in chkdesk and I'm only at 6 percent with around 500+ errors and still going. Yes, I've taken logs of the errors via cell phone camera and patience. A week or two prior to this happening I had to change our the hard drive due to blunt force trama next to the mouse. OH! Running on Windows 7: ) And I've tried loading the computer in safe mode and it makes absolutely no difference. Any and all help would be appreciated. I really don't know what to do from here and I'm kind of freaking out. I've googled different part of the error and things that I've done/seen and there are so many different answers/topics that I thought it best to just post the questions.

• Windows takes a very long time to shut down even in safe mode

  - by user1526247

  On Windows 7 the computer freezes for about 5 minutes once it gets to "Shutting down...". I can't remember when it started happening. I just lived with it for a while. The first thing I tried was a full scan using Microsoft Security Essentials. This did not solve the problem. I then went into msconfig and turned off everything I could get away with in the startup and services tabs. This did not solve the problem. I then uninstalled every program on this computer save the most basic programs. This did not solve the problem (did not uninstall drivers or catalyst). I then went through and turned off every single service and did a reboot. This did not solve the problem. I then booted into safe mode and just tried shutting it down. The problem even happens in safe mode. I have tried examining the event logs but with no success. They just say things like "blah blah has entered the stopped state" with no real clues about what program is causing me all this grief. *it may be worth noting that Ubuntu is installed on the same computer and the ubuntu boot loader is the one being used.

• How to make a redundant desktop system with daily snapshots? (Is btrfs ready for use?)

  - by TestUser16418

  I want to configure a desktop system in which the home filesystem would be redundant (e.g. RAID-1), and would have weekly snapshots taken. I've already done this with ZFS, the snapshot system is wonderful, and with send/recv you can easily create backups on external media. Unfortunately, at that point, I want GNU+Linux and not FreeBSD or Solaris, so I'm looking for suggestions for good alternatives. I reckon that my alternatives are: btrfs - it seems to be exactly what I need, it has snapshots and commands that allow you to easily replicate zfs send. Yet all documentation mentions that it's still experimental. I can't seem to find any actual reports on its reliability or usability issues. Can you point me to any information on that issue that could clarify whether it would be a possible choice? I have a large preference for this option, mostly because I don't want to reformat the drives when btrfs becomes ready, but I there's no information on whether it's usable at all, whether it's a silly idea to use it, etc. The question that I cannot get the answer to is what does "experimental" mean. lvm snapshots and ext4 - preferably not, since it can consume an awful amount of space when new files are created. Creating 200 GB files requres 200 GB free space and 200 GB additionally for snapshots. I also have found it unreliable -- failed metadata rewrite results in an unreadable PV. I'm wondering how btrfs would compare here. A single filesystem (ext4) on a RAID-1 array with custom COW snapshots with hardlinks (like cp -al). That's my current preference if I can't use btrfs. So how experimental btrfs is, which should I choose, and do I have any other options? What if I don't keep external incremental backups, would that affect my choice?

• Vim: auto-comment in new line

  - by padde

  Vim automatically inserts a comment when I start a new line from a commented out line, because I have set formatoptions=tcroql. For example (cursor is *): // this is a comment* and after hitting <Enter> (insert mode) or o (normal mode) i am left with: // this is a comment // * This feature is very handy when writing long multi-line comments, but often I just want a single line comment. Now if I want to end the comment series I have several options: hit <Esc>S hit <BS> three times Both of these afford three keystrokes, taken together with the <Enter> this means four keystrokes for a new line, which I think is too much. Ideally, I would like to just hit <Enter> a second time to be left with: // this is a comment * It is important that the solution will also work with different indentation levels, i.e. int main(void) { // this is a comment* } hit <Enter> int main(void) { // this is a comment // * } hit <Enter> int main(void) { // this is a comment * } I think I have seen this feature in some text editor a few years ago but I do not recall which one it was. Is anyone aware of a solution that will do this for me in Vim? Pointers in the right direction on how to roll my own solution are also very welcome.

• Multiple Screen - Keyboard Sharing

  - by nhbdesign

  I run a small architectural firm with several drafters employed, I'm currently setting up a new office space and one of the things on top of my list is a figuring out a way to keep tabs on my drafters work and being able to collaborate in real time. Here's the challenge, they sit in a separate large cubicle room and I'm on the other end of the hallway, the way it is now; every time they’ve got some question on how to proceed on a certain design, they would come all the way to my office, I'd open their file (in read only) give some ideas, save-as new file, they go back copy paste... in short, nonsense. What I've been thinking of is to setup a hardwired solution that should enable me to have an extra monitor on my desktop which is hardwired (through KVM or something) to each of my employees workstations serving as a secondary display, so that I can watch live what they do, interact with them just as if they would have an extra keyboard and monitor in my office, except; I don’t want to have on my desk a separate monitor for each employee.. so I'd want them to be tiled on a single large screen, watching all screens alive, and whenever they ask me (or I just decide..) to step in, I just click on any tile and hurray, I'm in, editing and saving in real time on their workstation. I also want to reserve the option when I want to, to just use that monitor as just an extra screen for my workstation. Is something like that possible in 2013? P.S. I know of TeamViewer and similar internet/software based stuff, but I'm specifically looking for something solid hardwired and maintenance free, and also something that would allow to watch without my employees getting notified every time I do so (I’m not a tough boss though...).

• Is there such a thing as a file hosted container which deduplicates data held within?

  - by Mallow

  Background I have backups of a website which stores all of it's data into a single file. This file is several gigs large and I have many different backups of this file. Most of the data within is mostly the same plus whatever was added or changed to it. I want to keep all the concurrent backups I've made through the years in case I find a horrible surprise of data corruption along the line. However storing a 10gig file every month gets expensive. Seeking Solution I've often thought about different ways of alleviating this problem. One thought that comes up very often combines the idea of a duplicating file system which doesn't require it's own partitioned volume on a hard drive. Something like what truecrypt does, what it calls, "file hosted containers" which when using the truecrypt program allows you to mount and dismount that volume as a regular hard drive. Question Is there a virtual hard drive mounter which uses file-based container which uses data deduplicaiton file system? (This question is a little awkward to put into words, if you have a better idea on how to ask this question please feel free to help out.)

• ProxyPass for specific vhost

  - by Steve Robbins

  I have a web server that it set up to dynamically server different document roots for different domains <VirtualHost *:80> <IfModule mod_rewrite.c> # Stage sites :: www.[document root].server.company.com => /home/www/[document root] RewriteCond %{HTTP_HOST} ^www\.[^.]+\.server\.company\.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^www\.([^.]+)\.server\.company\.com(.*) /home/www/$1/$2 [L] </IfModule> </VirtualHost> This makes it so that www.foo.server.company.com will serve the document root of server.company.com:/home/www/foo/ For one of these sites, I need to add a ProxyPass, but I only want it to be applied to that one site. I tried something like <VirtualHost *:80> <Directory /home/www/foo> UseCanonicalName Off ProxyPreserveHost On ProxyRequests Off ProxyPass /services http://www-test.foo.com/services ProxyPassReverse /services http://www-test.foo.com/services </Directory> </VirtualHost> But then I get these errors ProxyPreserveHost not allowed here ProxyPass|ProxyPassMatch can not have a path when defined in a location. How can I set up a ProxyPass for a single virtual host?

• How to fix missing RAID1 drive

  - by Sodved

  I had to do some fiddling about with my cables inside thebox and now I am getting a "Critical Error" about the RAID disks during startup. I have a gigabyte GA-MA770T-UD3 motherboard. Aparently the RAID controller is an AMD SB710 chip. I'm pretty sure I know what happenned. The first time I rebooted I had forgotten the power cable on one of the disks in the RAID1 (mirror) and let it boot up. So I shut down and put the power back in. So now when it boots up I go into the RAID admin interface (between the BIOS screen and the OS loading): it shows the RAID1 as in error the logical device has one disk and says the other is disconnected or missing the other physical disk shows up as a single disk If I boot to the OS (Windows 7 32 bit) the data all seems to be there. If I go into computer management it says my partition is on a disk and working OK. But the other disk is offline because: "The disk is offline because it has a signature collision with another disk that is online" So I am guessing because I STUPIDLY booted up with only one of the disks powered on, the other disk fell out of synch with the mirror and so now cannot rejoin the mirror. How do I fix this? I want to get the RAID1 mirror working again. There does not appear to be any "Repair" option in the basic RAID admin tool which I get into during startup before the OS boots. I have not made any explicit changes to the online one (but I guess the OS has probably written some admin data).

• Can my employer force me to backup my personal machine? [closed]

  - by Eric B

  Here's the background: Approximately 1.25 years ago, the company I work for was acquired by a larger 400 person company. Before acquisition (and today still) we are all remote employees using our own personal hardware for work-related duties (coding, email, etc). We are approximately 15 employees within the larger organization. Some time after acquisition, the now owning company was slapped with a civil lawsuit. Part of this lawsuit (discovery) is requiring them to retrieve & store from us any related information. Because we were a separate company up until acquisition, there is a high probability that our personal machines might contain information about what the lawsuit alleges (email, documents, chat logs?, etc). Obviously, this depends largely on the person's job function (engineer vs. customer support vs. CEO). All employees are being required to comply. Since acquisition (1.25 yrs), the new company has not provided us with company laptops/desktops. We continue to use personal hardware, licenses, etc for work. Email is via POP3s and not hanging around on the mail server - it's on everyone's client. Documents are spread across personal machines. So, now they want us each to backup our complete personal machines. They are allowing us to create a "personal" folder where we can place personal documents. That single folder will be excluded from backup. Of course, that means total re-arrangement of documents, etc. For most of us, 99% of the data on the machine is NOT related to work. So, what's the consensus? Should we comply? What is their recourse if we do not?

• Why is "start in" needed for Windows scheduled tasks?

  We develop a web application that can be deployed on Windows or Linux. The Linux implementation uses cron, and the Windows one uses scheduled tasks to run a single PHP script that processes all scheduled tasks for our system. The task is scheduled using schtasks during the install process, like: This has always worked both under W2003 and W2008. A week ago a customer reported that scheduled tasks were not running. He is running on Windows 2008. We checked over and over and finally solved the issue by entering the folder that contains the .vbs script as the "start in" folder for the scheduled task. This said, there is no way to set up the "start in..." value from schtasks without using an XML definition of the tasks. XML definitions don't work in Windows 2003, so I would have to add windows version detection to the installer, additional testing, etc (I'd like to avoid this if at all possible). The only atypical thing I noticed about the install is that the system is installed in D:\ as opposed to the default C:\Program Files (x86)\, but I don't see how this would matter. All the paths are absolute in all the scripts. Can anyone suggest a reasonable solution for this?

• Locate devices within a building

  - by ams0

  The situation: Our company is spread between two floors in a building. Every employee has a laptop (macbook Air or MacbookPro) and an iPhone. We have static DHCP mappings and DNS resolution so every mobile gets a name like employeeiphone.example.com, every macbook air gets a employeelaptop.example.com and every macbook pro gets a employeelaptop.example.com on the Ethernet interface (the wifi gets a dynamic IP from a small range dedicated for the purpose). We know each and every MAC address of phones and laptops, since we do DHCP static mapping (ISC DHCP server runs on linux). At each floor we have a Netgear stack of two switches, connected via 10GB fiber to each other. No VLANs so far. At every floor there are 4 Airport Extreme making a single SSID network with WPA2 authentication. The request: Our CTO wants to know who is present at which floor. My solution (so far): Every switch contains an table listing MAC address and originating port. On each switch stack, all the MAC addresses coming from the other floor are listed as coming on port 48 (the fiber link). So I came up with: 1) Get the table from each switch via SNMP 2) Filter out the ones associated with port 48 3) Grep dhcpd.conf, removing all entries not *laptop and not *iphone 4) Match the two lists for each switch, output in JSON or XML 5) present the results on a dashboard for all to see I wrote it in bash with a lot of awk and sed, it kinda works but I always have for some reason stale entries in the switch lookup tables, making it unreliable; some people may have put their laptop to sleep, their iphones drop connections after a while, if not woken up and so on..I searched left and right, we are prepared to spend a little on the project too (RFIDs?), does anybody do something similar? I can provide with the script if needed (although it's really specific to our switches and naming scheme). Thanks! p.s. perhaps is this a question for stackoverflow? please move if it so.

• Optimize Apache performance

  - by Phliplip

  I'm looking for ways to optimize our current web server hosted in-house. I'm trying to supply as much relevant information below. Please let me know if you would require additional information in order to assist. Server is running 1 single website, which is an online pizza ordering platform built on Zend Framework (ver1). On traffic stats from the last month aprox 6.000 pageloads per day, concentrated mainly around dinnertime. Around 1500 loads/hour peaks in that period. We recently upgraded from a 2/2mbit aDSL-line to 100/100mbit fiber, and we still have performance issues at dinner time. We assumed the 2mbit was the issue. Website is pretty snappy in low-load periods. Hardware CPU: Intel(R) Xeon(R) CPU 5160 @ 3.00GHz (3000.13-MHz K8-class CPU) Mem: 328M Active, 4427M Inact, 891M Wired, 244M Cache, 623M Buf, 33M Free Swap: 16G Total, 468K Used, 16G Free (6GB physical, 16GB swap) Filesystem Type Size Used Avail Capacity Mounted on /dev/ad7s1a ufs 4.8G 768M 3.7G 17% / devfs devfs 1.0K 1.0K 0B 100% /dev /dev/ad7s1g ufs 176G 5.2G 157G 3% /home /dev/ad7s1e ufs 4.8G 2.8M 4.5G 0% /tmp /dev/ad7s1f ufs 19G 3.5G 14G 19% /usr /dev/ad7s1d ufs 4.8G 550M 3.9G 12% /var Server OS FreeBSD 8.2-RELEASE Software apache-2.2.17 php5-5.3.8 mysql-server-5.5 Apache footprint (example, taken from # top) 31140 www 1 45 0 377M 41588K lockf 2 0:00 0.00% httpd 31122 www 1 44 0 375M 35416K lockf 2 0:00 0.00% httpd 31109 www 1 44 0 375M 38188K lockf 2 0:00 0.00% httpd 31113 www 1 44 0 375M 35188K lockf 2 0:00 0.00% httpd Apache is using the prefork MPM, APC (Alternative PHP Cache). SSL module is loaded, but not utilized (as in don't really work, thus not used). There is a file containing settings for MPM modules, but as i see it's not included in the httpd.conf file, the include line is commented out. Thus i would guess that the prefork MPM is working of default values too. Here are some other Apache conf values that i found - which are included in https.conf Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 UseCanonicalName Off HostnameLookups Off

• How many guesses per second are possible against an encrypted disk? [closed]

  - by HappyDeveloper

  I understand that guesses per second depends on the hardware and the encryption algorithm, so I don't expect an absolute number as answer. For example, with an average machine you can make a lot (thousands?) of guesses per second for a hash created with a single md5 round, because md5 is fast, making brute force and dictionary attacks a real danger for most passwords. But if instead you use bcrypt with enough rounds, you can slow the attack down to 1 guess per second, for example. 1) So how does disk encryption usually work? This is how I imagine it, tell me if it is close to reality: When I enter the passphrase, it is hashed with a slow algorithm to generate a key (always the same?). Because this is slow, brute force is not a good approach to break it. Then, with the generated key, the disk is unencrypted on the fly very fast, so there is not a significant performance lose. 2) How can I test this with my own machine? I want to calculate the guesses per second my machine can make. 3) How many guesses per second are possible against an encrypted disk with the fastest PC ever so far?
