• Which is the cheapest machine where I can run linux and plug in some webcams? (and with network inte

  - by marc.riera

  I'm looking for a very cheap machine to run a linux distro for security(anti-thief) software. I would like to be able to connect to the network and a couple of webcams. May be ip-webcams or usb-webcams. The idea is having a machine with batteryes, laptop style, but there is no need to have a display/monitor attatched all the time. I'm planning to spend no more than 200$, in case it also gets stolen. Any advice on what to buy? (all modifications to this security plan are welcome) Thanks.

• Can I reprogram a microphone input to be used as an audio output? (on XP)

  - by qftme

  I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

• Avoid putty ssh terminal to crash when disconnecting from server

  - by JBoy

  I'm connecting via ssh to a remote 'live' server where i have some bash scripts automated via the crontab, when an error happens in some of the automation scripts within the server, the connection to the server is killed, this is fine to me, but the problem is that Putty closes the entire window, which is a behavior i don't want. I have checked all around the web, unfortunately the putty site does not have a support page, but nothing. Under putty's option i have tried all the menus expanding all options, but still i cant find the right one, i would expect it to be under Windowbehaviour Do you have an advice? Thx

• Windows 7 Hibernate Problem

  - by goygoycu

  I cannot hibernate windows. When I click "hibernate", my laptop(windows) just locks and the screen goes black. I can unlock without any problem. I do not have any problem with other options such as "sleep" or "shut down". I updated the chipset drivers but it did not help. There is not any option in BIOS about the sleep modes. "Hibernate" is "on" on Windows. Any advice? My Laptop specifications: MSI A5000 3gb system memory, Windows 7 Home Premium 32bit installed, Gentoo linux installed, Grub bootloader(MBR). Hard drive: Around 4gb of free space in windows partition.

• Any way to disable specific CPU idle (Cx) states?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

• PHP / Drupal equivalent of .bat file [closed]

  - by Pamela

  I am new to Drupal and have just started in Drupal 7. I have a very simple .bat file that calls a .txt file to open a ftp connection, get a file off the ftp server and place it on my desktop. Now that I know that works.. (YAY!) I need to figure out how to have it done with a cron job in Drupal, save it somewhere so that I can unzip it somehow and then populate a table in the database with it. Any advice would be greatly appreciated!

• Request to server x Reply from server y

  - by klaasio

  I need some advice from you guys: I'm dealing with a custom loadbalancer/software for which we will use 2 main servers and about 8 slave servers. In short: User sends request to main server, main server will receive and handle the requests, sends a request to a slave server and slave server should send data DIRECTLY to the "user". User - Main server Main server - Slave server Slave server - User The reason for which data should be send directly to the user and not through the main server is because of bandwidth and low budget. Now I have the following idea's: -IPinIP, but that is not possible in Layer7 (so far i know there some expensive routers for that) -IP Spoof, using C/C++ we will make it look like the reply came from main server. But I was thinking, perhaps the reply "slave server - User" could just come from a different IP without causing issues in the firewall from the user or his anti-virus. I don't know so well about "home" firewalls/routers and/or anti-virus software. I guess the user machine wouldn't handle it well?

• Sending email with Windows 8 Mail (Modern UI) being blocked by AVG Firewall

  - by Riaan

  I've setup my Outlook.com email address in Windows 8 Mail (Modern UI) but is unable to send and receive emails when my AVG Internet Security 2012 Business Edition's Firewall is enable. When I disable the firewall, the emails are coming through and are being send. I know that I can most probably open the ports for IMAP on the firewall, but instead I would like to permit the application. Where/how do I find the application path for Windows 8 Mail (Modern UI) to allow all network traffic? (AVG did not show its normal Allow/Disallow notification for 1st time communications) Any advice would be appreciated.

• MongoDB PHP EC2 Setup Configuration

  - by nathansizemore

  I am new to web development and server set up. I am looking for some advice or a link to a tutorial on setting up a production system up. Right now, I have a server (Ubuntu, Apache, MongoDB, and PHP). It receives a request, PHP queries Mongo, and PHP sends out the requested data. How do I make that work with more servers? I've read that you can make a cluster of a primary and two slave nodes which work as separate servers running Mongo, but do those also run PHP? Or is the primary the only one running the PHP? I have read some docs on Mongo site and a video of someone from 10gen going through it, but they are geared towards people that seem to already understand this stuff, I have no idea and need to start from a beginning stage. If anyone can help me understand where PHP (Acting as my API) lives in these clusters, that would be greatly appreciated! Thanks in advance for any help!

• PHP5.3 FastCGI doesn't use global config's values

  - by mega.venik

  There's a Centos6.3 system. Apache 2.2.15 + mod_fcgid + PHP 5.3.3 There's a problem with date.timezone value. It's mentioned in the global /etc/php.ini like this: date.timezone = "Europe/Moscow" And doesn't mentioned in user's local php.ini. As a result, I'm getting lot's of warnings like: Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Helsinki' for 'EEST/3.0/DST' instead in ... Including the date.timezone parameter into the user's php.ini solves the problem, but I don't think, that it's the best solution. Maybe someone have faced this problem and can give an advice? Thanks! P.S. Creating /etc/php.d/timezone.ini with the timezone info aslo does nothing:(

• Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

  - by Minix

  I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

• converting 0+1 raid array to 0

  - by werelord

  I'm currently running raid 0+1; four 500 GB drives in the array.. I'm looking at migrating the array from 0+1 (Stripe+Mirror) to 0 only (stripe).. The goal is to remove the hard drives from the array in order to put them in the newly purchased Drobo, then copy the data from the remaining striped raid to the said Drobo.. Is it sufficient to just remove the drives themselves and change the raid configuration within the nvidia raid config?? Or is there something more that needs to be done?? Does the order matter (i.e. removing drives first or changing the raid configuration??) Is it possible to migrate the array this way without having any loss of data? I'm wary about burning all that data to DVDs (few hundred GB worth) to back it up.. Any other advice from people that may have done this (or have other insight) would be helpful as well..

• Correct usage of Windows Server on network?

  - by Hobart Bosworth

  I have two routers, one with dhcp turned on and the other with it off. this is a functioning home network. Now, I am trying to integrate into it a windows server. Should the windows server be doing the dhcp and dns work? And if so, what will this mean for the existing network? Will I need to reconfigure this? I am currently installing server 2003 onto my server machine. It is connected up to the network on the main router with dhcp. Any words of advice?

• Single PC Satellite Office Firewall

  - by Carl

  We are setting up a small, single PC office about 200 miles away. We plan on getting a cable internet connection but need some advice on a sufficient firewall. We would like to keep it under $100 if possible. 2 options we are considering are: Cisco RVS4000 (got some bad reviews) Linksys WRT120N (running DD-WRT) We need the ability for VPN but other than that we don't need anything special. We just want to keep that PC as safe as possible but easily maintainable because most work will be done remotely. What suggestions or solutions can you recommend for this application?

• Dead USB flash drive

  - by Unsliced

  So a friend has come to me with a problem. They have a dead USB thumb drive which no longer responds when plugged into a machine. I've tried it in a Mac and it doesn't even respond, at least on a Windows XP machine it sees that it is there but can't show it in explorer, just that whatever is plugged in has malfunctioned. There is obviously current because the activity light on the drive illuminates. I'm looking for suggestions, please. I have access to Mac or Windows hardware and am happy to experiment (and even to pay if the solution works!) It's a bit late to recommend regular backups, but in the lack of that, what's the next best forensic advice? Edit: I should stress that, if possible, we're trying to rescue the data, after all, thumb drives are basically disposable and hardly worth the bother if there's no emotional or functional reason for wanting to rescue it!

The Error thrown is : Can't connect to MySQL server on 'xx.x.xxx.xx' (111) Reloading the page often solves the problem The client is using Perl, DBI and SSL to connect to MySQL using the same configuration file each time.

The servers firewall is open to the client's subnet. The mysql user has permissions from the client's subnet. I have my host looking into the problem but so far we're all stumped as to way the occasional connection is (increasingly getting refused) Any advice what to check that would cause the random refusal of connections?

• Personally identifiable information (PII) on shared web hosting

  - by S. Cobbs

  Hey folks, I am providing web hosting services (shared and dedicated) and have had one of my shared hosting clients mention needing an SSL cert for their site where they are collecting insurance quotes in a form, including names and social security numbers. My privacy sense is tingling, and I'm pretty sure it's not legal (in the US) to do this on a shared system, but can't find anything to support my thoughts outside of PCI-DSS, but the customer isn't processing payments through the site so I'm not sure if that applies. I'm reading lots of policy documents where people advise to minimize and manage the PII footprint internally, but as the host I don't want to put all of my customer's clients at possible risk. I'm not looking here for legal advice necessarily, but perhaps someone in a similar position to mine can provide some rule of thumb or point me in the right direction.

• Application got shut down in WinXP if I close the 2nd window of that application.

  - by kinopyo

  I'm using WinXP and here is my question: I run an application, such as Chrome, there would be one app in the task bar, and it's fine. Suppose a new window of Chrome opened(so there would be 2 window and 2 in the task bar), and when I close that,the 2nd one, the whole application just shutdown. And so does chrome, firefox, evernote, Becky!(the email client), even TortoiseSVN. So I think there should be a generic problem cause these applications shutdown, such as the platform - WinXP. Please give me some advice or hint, anything comes to your mind would be helpful!

• Backing Up User Data when data is not in use. Should I be concerned?

  - by jberryman

  This may be a dumb question. I would like to use duplicity to make backups to Amazon S3 of directories, each of which contains a different user's data. Each directory could be written to at any time. So I have two questions: Should I be concerned that a scheduled backup of a directory might occur in the middle of data being written to files in the directory, resulting in a corrupted backup? And if that is a valid concern, how would I go about temporarily delaying an operation while IO was happening, to try to minimize that effect. Thanks for the advice

• VPN between Cisco ASA 5505 AND Sonicwall SOHO3

  - by user41451

  Hello. I am trying to establish a site-to-site VPN tunnel between an old SOHO3 and an ASA 5505. The ASA has a static IP and the SOHO3 is dynamic. I have tried everything my limited knowledge lets me and need some advice on how to proceed! Phase 1 (according to the ASA logs) completes - followed by a message saying "All IPSec SA proposals found unacceptable!" so I guess the settings between the two don't match. I have played with various combinations and nothing seems to work - I am overlooking something, just not sure what it is! Any help would be appreciated.

• Weblogic Class-Path Dependencies EAR

  - by Mo

  I am deploying an EAR in a WebLogic node with many jars defined in the bootstrap (startWeblogicServer.bat) class-path. The problem is that my ear and the bootstrap contain different versions of the same jars, not only that but certain jars contain extracted third party libraries which also differ in version from the WebLogic bootstrap jars causing all kinds of classpath errors. I know you can set preferred jars in the EAR application xml but, this can be very tedious to resolve with regards to jars which include extracted third party libraries in terms of understanding all the dependencies.. Is there a correct approach that i need to be taking here? Am i thinking about this in the wrong way? Any help would be greatly appreciated! So far prefer-web-inf-classes has been recommended but wont work because i'm not deploying a WAR, also prefer-application-packages is what we are currently using but still has the issue described above... Anymore advice out there?? Thanks!
