• Getting BootMgr not found errors repeatedly on Win7 x64

  - by abszero

  So here is the basic configuration of the box: Primary RAID 1 (Mirror, Bootable): 2x 300GB WD SATA drives AMD Phenom Quad Core x64 @2.2 ASUS M3N78 Pro Board 4GB RAM Win 7 Ultimate Additionally, this box is a Host OS for several CentOS Boxes via VirtualBox. The box runs like a champ but, for whatever reason, everytime I restart the machine I get a BootMgr not found error when the box tries to boot. I pop in my Win DVD, select 'Repair Windows' then 'Fix Start Up Problems' and everything works fine...once. When I restart the box again I have to go back through this process. Any ideas on what is going on?

• How can I join two simple home networks together using an ethernet cable?

  - by Ilia Jerebtsov

  I want to join two different home networks together like so: PC A1 PC A2 PC B1 PC B2 \ / \ / Gateway A <----- ethr. cable -----> Gateway B | | ADSL modem A ADSL modem B Both networks are of the basic residential type with identical configuration, with all PCs running Vista/7. The point is to temporarily join two apartments in a building for gaming and file sharing, and the holy grail would be: PCs on network A can access PCs on network B and vice-versa (file shares and gaming). Each network uses its own internet connection. Data between networks shouldn't take a trip through the internet (broadband upload speeds are severely capped) A network's internet access should continue working if the joining cable is disconnected with minimal configuration changes. How closely can this be achieved?

• How to get back to having OPEN IN SINGLE INSTANCE" as default for Excel 2007?

  - by rweeks

  In June Mikhail asked the same question but the answer was how to do the opposite (make multiple instances the default). I am trying to get to an answer to Mikhail's question which I rephrase as :- I have same problem with 64 byte Windows 7 and Excel 2007. Excel always used to open in a single instance n o matter how/where I opened the sheets. Because of this I could always copy and paste, etc with full formatting, formulas, etc. Suddenly, Excel switched to opening everything in fresh, separate, multiple instances and destroyed the basic cut and paste options. Wasn't the original question how to go back to everything in a single instance ? I have been searching for the answer to that question (rather than the opposite) Richard

• Firefox / Iceweasel hangs at exit

  - by mxp

  On my Debian (testing) system, I found that for some time now Firefox hangs when exiting. There is no window visible anymore and the process utilizes one CPU core to 100%. No other instances can be started until that process is killed. I tried the Basic Troubleshooting guide but that didn't help. Starting it with iceweasel -safe-mode and then choosing none of the options but just clicking "quit" caused the same behavior. Creating a new profile also didn't change anything. Any ideas what else I could try?

• How many cron jobs are too many?

  - by guitar-

  I have a couple of cron jobs for basic maintenance which aren't very resource-intensive. I also have custom task scheduling (which is just calling a .php file and passing information via GET, ie: cronjob.php?param1=param ...). These can add up pretty quickly. These just call system commands and run external programs (Nmap is one of them). They usually don't take long either. Anyway, can anyone tell me, roughly what point is too many? I know it's hard to say since it depends on what job is being run and how often, but at what point does the crontab program start "struggling"? Anyone have any idea? Thanks.

• Tips for teaching Linux to beginners?

  - by chiborg

  I will teach Linux to people of the ages 20-75 with no prior Linux knowledge. I want to teach some basic concepts (what's an OS, what's a file system) and some practical knowlede: How to install it, network configuration, set up email client, installing software with a packet manager, etc. I have held a system administrators course in the past, but was under the impression that my method of teaching was not adequate. I've explained what I was about to show, showed students on the projector, told them to repeat it on their computers and summarized what they should have learned. They could ask questions all the time. But I fear they remembered only one-third of the knowledge I taught them. I have two questions here: Are there better methods to teach this particular subject in a classroom equipped with computers? Are there some tricks that "slow me down" when I teach stuff that I know inside-out?

• SharePoint 365 / Office 365 helpdesk template

  - by PnP

  I want to use my current Sharepoint 365 for handling helpdesk tickets. I want a really basic helpdesk utility. I tried to install some applications templates and I couldn't. I found that Office 365 does not support application templates (am I right?) I tried to install the help desk template here and also the Help Desk here, but I didn't find a way. I've seen that there is a commercial app, but I'm interested in checking some other options (specially free options).

• Block a URL at browser level

  - by Farseeker

  Does anyone have a solution (that doesn't involve editing the hosts file) to block a particular URL from FireFox? Basic back story is that I'm trying to discipline myself. I'm spending FAR too much time over at Server Fault that I want to genuinely block the site from my work PC so that every time I find myself flicking to it during work time I can't see it, but I'd like to be able to disable it during my lunch break. (So I only spend 40 minutes a day there, rather than 4 hours). That said I don't want to block it at the router, nor for anyone else.

• PHP not working when accessed through a domain name, but works fine when accessed through IP

  - by Allister

  Done a basic setup of Ubuntu Server installing Apache, PHP and mysql through tasksel. When I browse to the IP address of the server it works fine and allows me to render PHP scripts fine. So I added a DNS entry for the server onto my local DNS server, calling it webdev.lazer.net When I go to this domain name through my browser it renders HTML documents fine but if I try to view PHP scripts it doesn't render and downloads in plain text to the browser (As if the PHP parser isn't rendering .php documents). I'm sure its some rookie mistake, but any help would be appreciated. Thanks

• "Windows was unable to complete the format" - Can't format flashdrive!!!

  - by Jake

  I have a 8GB Sandisk Cruzer USB flash drive that I had ruined a while back trying to make it bootable. Anyway now when I click on it I get a message that it needs to be reformatted to be used. So when I try to do that, the formatting starts and suddenly ends with the message "Windows was unable to complete the format". This happens no matter which file system I choose (NTFS, FAT32, exFat) and also which computer I try this on. I am now on a Windows 7 32 bit OS and before tries it on a Vista Home Basic machine. Anyone know any way around this issue? Many thanks.

• Understanding the Linux Root

  - by Zac

  I've been using Linux (Ubuntu) for about 2 weeks now and am still struggling with some basic concept surrounding the root user: (1) Some terminal operations (such as making subdirectories inside a FHS directory such as /opt) require me to prefix the command with sudo - why? I guess what I'm choking on is: if I'm already logged in as a valid system user, why do I have to be a superuser/root in order to modify things that the sysadmin has already deemed me worthy of accessing? (2) Is there a GUI (Gnome, KDE) equivalent to sudo? Is there a way to assume a superuser role through a graphical context, rather than from inside a new shell? (3) I can't access the /root directory logged in as myself... but I installed the system to begin with and was never asked to create a root account! How do I log in as root and gain access to /root?!? Thanks for all feedback & input!

  - by tom smith

  hi. sorry to have to ask such a basic question!! i've got fedora 13, trying to figure out how to change the "I Beam" pointer. earlier, i had a "thin" "I Beam" pointer in my gedit/term windows. now, I have a "thicker/shadow" kind of "I Beam" pointer when i move the mouse over the gedit/term windows. obviously, i've made some change, but i can't figure out what I changed, or where this attribute is set. i've checked google/irc, as well as looked through the "system-preferences-appearance" with no luck.. i saw the customize part of the gui, and could resize the "arrow" but nothing for the "I-Beam". this isn't critical, but it is anoying!! any thoughts/pointers would be helpful. thanks

• Email censorship system

  - by user1116589

  I would like to ask you about any censorship / moderation system. Basic workflow of events: Customer sends email to [email protected] from [email protected] ACME administrator receives notification and can moderate email After moderation administrator confirm an email and send it to [email protected] John answears to [email protected] Before the email is send it is moderated again by ACME administrator What is important, that this functionality is easy to do with some CMS/CMF systems. The problem is that we do not want to use an extra domain and force customer to login an extra system. Customer should only use his own email box or desktop email application. Thank you, Tomek

• PHP+AJAX with MySQL - Query every 2 seconds, too many in TIME_WAIT

  - by Ryan

  I have a basic HTML file, using jQuery's ajax, that is connecting to my polling.php script every 2 seconds. The polling.php simply connections to mysql, checks for ID's newer than my hidden, stored current ID, and then echo's if there is anything new. Since the javascript is connecting every 2 seconds, I am getting thousands of connections in TIME_WAIT, just for my client. This is because my script is re-connecting to MySQL over and over again. I have tried mysql_pconnect but it didn't help any. Is there any way I can get PHP to open 1 connection, and continue to query using it? Instead of reconnecting every single time and making all these TIME_WAIT connections. Unsure what to do here to make this work properly.

• Compiz command plugin won't register keyboard shortcuts

  - by David Moles

  Per this discussion I've enabled the Compiz commands plugin in order to try to bind some keyboard shortcuts to wmctrl actions. CCSM captures my keystrokes just fine, but no matter what keystroke I try or what command I bind it to (everything from my original intention of binding Super-1, Super-2 etc. to wmctrl -o 0,0, wmctrl -o 2560,0, etc., to binding Ctrl-Alt-Shift-L to gnome-terminal). Basic compiz shortcuts for window switching and so on -- even custom ones -- seem to work fine, but the command plugin doesn't seem to be working at all. I also notice the following symptom: when I open the keyboard shortcut tab in CCSM, the keyboard shortcuts often at first appear blank, though if you click on the blank button, the correct value is still there. Also possibly related, I've noticed that gnome-terminal doesn't seem to notice the Super key, though other apps (e.g. CCSM, Emacs) register it fine. Anyway, it seems like something's eating my keystrokes. Any ideas?

• Squirrelmail got error after installation whm

  - by Pleerock

  Just now installed whm/cpanel, created some accounts, created mail account in one of them and entered squirrelmail to check the mail. Unfortunately it gives me an error: Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129 Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:143 (php_network_getaddresses: getaddrinfo failed: Name or service not known) in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129 How do I fix it? I don't know exactly, but I read some sites and maybe the problem in dns? I changed ns1.com to ns1.myhost.com in a Basic cPanel & WHM Setup P.S. Im sure that it server configuration problem, not squirrelmail, other mail clients are not working too..

• How to install Oracle's exp / imp binaries

  - by Sotapanna

  I was browsing the net to find a solution, but I had no luck. :( How can I install Oracle's imp / exp binaries to my CentOS box without installing an Oracle Server? I'm accessing an existing Oracle database on another machine, so I only need a client here. I already installed sqlplus and its dependencies (oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm, and oracle-instantclient11.2-odbc-11.2.0.3.0-1.x86_64.rpm), but that didn't provide those tools. Do I really need to fully install Oracle? My aim is to suck a database dump from the Oracle to my CentOS box. If there is another way to do this without using exp I wouldn't feel bad about NOT using it, but it seems to me there is no alternative.

• Product Recommendation: Good job scheduler for windows servers?

  - by Bret Fisher

  Looking for a mostly-GUI tool that is low cost (less then $1k, but not required) and allows you to create scheduled tasks and jobs without writing vbscript, batch files, or powershell. Something simple that speaks SMB/CIFS, SMTP, LDAP, etc. for such things as "delete some files based on a list of folders from this text file" or "disable all users with expired accounts" or "delete all disabled users not in this AD group". I've seen some of the big multi-OS enterprise task automation systems and they just look way overkill. We're a windows-only shop, Server 2003 or newer and there's got to be a simple non-agent based product that is drag-n-drop for some of this basic automation. Today we use all three languages mentioned above, and the scripts are not as reliable as a workflow-based-tool would be. Thanks.

• Best SQL Server Configuration with this hardware.

  - by DavidStein

  I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

• My Mac is slow but don't know what's slowing it down

  - by duality_

  My Mac (Macbook Pro) is sometimes slow doing basic tasks, like browsing the web or something like that. If I open Activity Monitor, I have (maybe) one program that is about 10 % CPU, others are below 1 %. My CPU usage is not full. I still have more than 2 GB of free memory (out of 5 GB). There is no heavy I/O activity like copying files. My open programs are Google Chrome (6 tabs, none of which are in some way (flash, many DOM objects, Javascript) have IMO, except maybe Gmail), Activity Monitor, Finder, Sublime Text 2 (text editor) and iTerm (terminal). What is causing the slowdown? "Slow" being: taking time to write these characters (I press the keyboard keys but there is a delay before I see them on the screen), changing tabs or programs, etc.

• Cables for building a computer

  - by Faken

  I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

• How to create a Linux Media Server using Ubuntu?

  - by Thomas

  Hello all: I'm an intermediate Linux user and a relative beginner to servers. I would like some help finding resources on setting up a basic server. I have Googled, and am a member of the Ubuntu Forums, but just figure it can't hurt to ask the Stack Overflow community for help as well. I plan on installing on an old laptop (Lenovo Thinkpad R61i or Toshiba Satellite A105). I have downloaded the latest Ubuntu (9.10) but don't know how to do any of the configurations. I just want a server to store my files where I can access (download and/ or stream) from a browser. Any help you can give is greatly appreciated. Thanks! Thomas

• Nokia Pc Suite problems with bluetooth (win7)

  - by wurlog

  I have a new Nokia C5-00 and a HP 620. The Bluetoothdriver are installed and the windows Bluetoothstack finds the mobile. After installing Nokia PC Suite I am asked to choose a connection method. As I click on Bluetooth the Nokia PC Suite shows an error message: "Cannot use the connection type.Check that all the needd hardware,software and drivers are available. (Code: OpenMedia)" I tried to switch it on and off via the "wireless" key on the laptop. The HP Software for the button shows that the Bluetooth is deactivated and advices me to go to the device manager and activate the Bluetooth device. Strangely the Bluetooth symbol (I guess from the windows Bluetoothstack) pops up at the same time and I can use the Bluetooth in it's basic windows features, but still nokia suite won't work. ideas????
