• SQL server environment

  - by Olegas D

  Hello I'm considering a bit of changes in current sales environment. And trying to check all cons and pros. Current situation. SQL server (quite decent HP server - server1) + backup server (smaller Dell server - server2). all sql files and sql server itself are on the server1. If something goes wrong with server1 I will have to manually move to server2. Connecting to the sql server: 1 HQ (where server located) + 4 sites through VPN. Now I'm considering 2 scenarios: Buy some storage system + update existing servers (add ram, upgrade processors) and go for VMWare ESXI. Rent a server at a datacenter + rent virtual server in case real server goes down. Also rent some space at data storage to keep SQL files there. Have anyone considered these things and maybe found some good pros/cons list? ;) Thanks

• Missing menu items for Azure SQL tables within SQL Server Management Studio?

  - by Sid

  I have a table (say Table1) that is replicated via SQL Data Sync Agent across a local SQL Server 2012 as well as an Azure SQL Server (part of Microsoft Azure). Everything about Table1 (schema, table values etc ) is identical to the best of my understanding. However, when I list and right click Table1 from Microsoft SQL Server Management Studio 2012 (SSMS), I get some very different menu options, even for seemingly basic stuff. Lets focus only on the 'Design' menu item: It is visible for Table1 on the local SQL server in SSMS It is missing for Table1 on Azure SQL via SSMS It is visible for Table1 (as Open Table Definition) on Azure SQL when reaching it via Visual Studio 2012 (Server Explorer - Data connections) This is seen in the screenshots below: Now I use scripts from some real stuff (esp when I need to check in the SQL scripts etc) but this difference concerns me to some extent. Am I witnessing just a tools artifact in SQL Server Management Studio when connecting to Azure SQL? or is it something more serious about limitations of Azure SQL itself (although, just seeing the Design surface is so basic!)?

• Debian, CentOS, Slackware, FreeBSD, OpenSolaris and Ubuntu Server Edition: Which one to use for an http web server?

  - by Ako

  I am going to install and administrate a virtual server for a small university. The server should run inside a virtual machine (VirtualBox OSE). It is only used in the university network and is invisible to the outside world. It should run Apache web server for PHP, MySQL and probably a mail server. I don't know which OS to use. Main criteria for choosing include ease of administration and updating, package management and performance. I wonder if anyone has any suggestions? And candidate OSs are: Debian, Ubuntu, CentOS, Slackware, FreeBSD, OpenSolaris. Add any other OS if you know any better alternatives.

• Load balancing + NAT issue on BNT GBE 2-7 gear

  - by Clément Game

  Hi guys, I've got troubles configuring an Hardware load-Balancer with NAT functions. I have the following architecture: Internet === VIP (public) LB (private ip) ==== private addressed servers When a connection is initialised from the outside (internet) , the LB correctly forwards the SYN packet to one of the private servers. But when these servers want to reply with a SYN/ACK there is a problem. the initial SYN packet had as ip header : VIP = Private_server_Address But the private servers cannot reach VIP from their side (this is normal since it's nated), and then provide a correct reply. Have you guys any solution to correctly forward the packets to their correct destination ? Note: The load balancer, which is the default gw for the servers, also has a NAT rule for "masquerading" (actually more SNAT than real masquerading) Regards, Clément.

• scp to remote servers stalls, unable to isolate cause

  - by Rolf

  When I copy a large file (100+mb) to a remote server using scp it slows down from 2.7 mb/s to 100 kb/s and downward and then stalls. The problem is that I can't seem to isolate the problem. I've tried 2 different remote servers, using 2 local machines (1 osx, 1 windows/cygwin), using 2 different networks/isps and 2 different scp clients. All combinations give the problem except when I copy between the two remote servers (scp). Using wireshark I could not detect any traffic volume that would congest the network (although about 7 packets/sec with NBNS requests from the osx machine). What in the world could be going on? Given the combinations I've used there doesn't seem to be any overlap in the thing that could be causing the trouble.

• Nginx + PHP-FPM ignores no-cache headers

  - by Eric Winchell

  I'm using the following header on a php page. // Prevent page caching. header('Expires: Tue, 20 Oct 1981 05:00:00 GMT'); header('Cache-Control: no-store, no-cache, must-revalidate'); header('Cache-Control: post-check=0, pre-check=0', FALSE); header('Pragma: no-cache'); I'm also using a rand=999999999 (with a real random number) in the URLs. But pages are still being cached. Reload works, but first load is cached. Anyone know where I can change this?

• application that could track amount of downloads

  - by user23950

  My ISP only limits me for downloading about 25gb a month. After exceeding the limit, my speed goes down by half for another month. And its really a pain. I'm real addicted on downloading stuff from the internet. My question is: Is there an application that can track the amount/size of downloads in a month. Is there a trick that I could use to fool the eyes of my ISP. If they say 25 Gb limit in a month. Does it include the webpages, manga streams, video & audio streams. Or just direct download and p2p.

• Rsync over ssh with root access on both sides

  - by Tim Abell

  Hi, I have one older ubuntu server, and one newer debian server and I am migrating data from the old one to the new one. I want to use rsync to transfer data across to make final migration easier and quicker than the equivalent tar/scp/untar process. As an example, I want to sync the home folders one at a time to the new server. This requires root access at both ends as not all files at the source side are world readable and the destination has to be written with correct permissions into /home. I can't figure out how to give rsync root access on both sides. I've seen a few related questions, but none quite match what I'm trying to do. I have sudo set up and working on both servers.

• What tool can I use to definitely kill a process on Windows?

  - by Moak

  Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP? I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down. I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

• Retrieve malicious IP addresses from Apache logs and block them with iptables

  - by Gabriel Talavera

  Im trying to keep away some attackers that try to exploit XSS vulnerabilities from my website, I have found that most of the malicious attempts start with a classic "alert(document.cookie);\" test. The site is not vulnerable to XSS but I want to block the offending IP addresses before they found a real vulnerability, also, to keep the logs clean. My first thought is to have a script constantly checking in the Apache logs all IP addresses that start with that probe and send those addresses to an iptables drop rule. With something like this: cat /var/log/httpd/-access_log | grep "alert(document.cookie);" | awk '{print $1}' | uniq Why would be an effective way to send the output of that command to iptables? Thanks in advance for any input!

• 250k connections for comet with node.js

  - by Nenad

  How to implement node.js to be able to handle 250k connections as comet server (client side we use socket.io)? Would the use of nginx as proxy/loadbalancer be the right solution? Or will HA-Proxy be the better way? Has anyone real world experience with 100k+ connections and can share his setup? Would a setup like this be the right one (Quad core CPU per server - start 4 Instances of node.js per Server?): nginx (as proxy / load balancing server) / | \ / | \ / | \ / | \ node server #1 node server #2 node server #3 4 instances 4 instances 4 instances

• Multi-account Google Apps Calendar Free-busy status?

  - by Andrew Bolster

  I have 3 google apps domain accounts and a personal google account, and until recently, there was little need for the google app's calendars to have any real use; Now however the powers that be finally discovered the smart re-scheduler and the other google tools for managing meetings and schedules; unfortunately I'm now in a position where I've got events notifications all over the place and because each of the calendars do not know about each other, I'm losing all of the advantages of rescheduler / free-busy status. TL;DR, 4 calendars, unified 'free busy' status without having to manually copy every event please.

• Optimal Instance Size for EC2 Sharepoint Server

  - by Rob Wilkerson

  I'm surprised that I can't find any info about this, but I'm not a Windows admin and just a novice EC2 user. I have a client who wants to stand up a Sharepoint server on EC2 for internal use. The team is small (10-20) folks and traffic will be light. Mostly, the client is looking for one place to store documents (and revisions of documents) while making access easy for authenticated users anywhere in the world. They've settled on Sharepoint and have other EC2 instances so that seems like the natural fit, but I'm trying to figure out what to recommend for them. I'm currently thinking about a Medium instance. I'm afraid to go smaller because I think Windows would need a fair amount of memory just to run, but I'm very open to suggestions. Any advice would be much appreciated. I expect that the storage itself would happen in an EBS mount, but again, suggestions welcome. Thanks for your input.

• Remapping special keys on the keyboard

  - by thedude

  Hey there. I just bought a new keyboard today, and to my suprise it doesn't include "Next/Previus track" keys, although it has other media keys. It also has useless keys like "Home" which brings up the webbrowser. Or well, it's not actually the "Home" key, it's a special key on the keyboard with a house on it - no idea what it's called. Anyway, so i'd like to remap the "House" key to "Next track". I've tried three different remapping programs now and none of them seem to be working. I think the real problem is that it's a special key, so it's not included in any keyboard remapping applications. The keyboard is a Logitech, can't seem to find the exact model though. Any tips?

• How to change the Windows 7 taskbar icon spacing?

  - by bill weaver

  At home i run Windows 7 with on a widescreen LCD with the taskbar to the left and this works well, but at work i just got upgraded to W7 on a 4:3 LCD and have the taskbar at the bottom. So what's with the taskbar icon spacing? Is there any way to change this? I.e. move them closer together? There's gotta be a registry setting or some fancy Tweak UI application that will reclaim some of that elbow room. That image above represents nearly half the width of my desktop. I know i know, white space is great and it gives it a light, whimsical look. Blah blah. Awesome, but can i get some real estate back please?

• create a bootable usb to automatic repair windows xp system32 files

  - by Edo Post

  Is it possible to create a script/live distro that replaces some system32 files? To explain it a bit more in details: There is a company that has multiple computers (think in 100/1000's) and they all are missing the same system32 files since the company's software removed it. The systems are distributed all over the world and are managed by "normal" people who don't have any knowledge about computers. I want to create a usb stick that i can mail to all those people which contains a script that executes when you boot the usb. this script should replace the missing system32 files without any user input is this possible, and if so how could i manage this?

• ext4: error loading journal

  - by cloudyOutside

  I have an external hard drive with two partitions: A small FAT32 which is mostly empty and works fine and a large ext4 with tons of data, most of which isn't backed up. The ext4 is visible, but can't be mounted. I get an "error loading journal" error. The drive is a Western Digital Caviar Blue 500GB. Roughly 30GB of that is FAT32 and the rest is the ext4. The light on the enclosure turns red when reading from the bad partition. It was made by Cavalry. There wasn't any warning, but coincidentally, I've been thinking lately that I should get two large capacity drives for real backups. Is there anything that can be done? I'm not even sure I have enough storage to backup everything even if it is redeemable.

• How to make a quiet laptop?

  - by psihodelia

  Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be PDF/docs processing, real-time audio processing, web-surfing and Skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend any solution please?

• Problems with Black Box KVM

  - by MrWizard54

  I just recieved a shipment of equipment orderd by my predicessor that includes brand new Dell Optiplex 990 computers, with standard mice and keyboards. Also included were Black Box ServSwitch Secure KVMs. I've worked with KVMs before and hypothetically they should be the easiest thing in the world to deal with, plug it all together, push the button, go. However, for the life of me I can't get the computers to recognize the mouse or keyboard when plugged into the KVM. We've seen this with multiple KVMs across the order. Any one know what I'm missing? Computers are all Dell 990 with Windows 7.

• ESXi 5.1 - Unable to register host

  - by deanvz

  I download and successfully installed ESXi 5.1. I am however unable to get the licence key I received installed. An error occurred when assigning the specified licence key: The system Memory is not satisfied with the 32 GB of Maximum memory limit. Current with 80.00 GB of Memory. Is there now way around this? A quick google revealed that this is a global problem with no real answer or resolution. The only workaround is to remove the physical RAM chips, but as this is in going to be in production I dont want to do that as it would mean down time when I have to reinsert the memory

• scp -q isn't quiet between different hosts

  - by pythonic metaphor

  So scp -q file host:file and scp -q host:file file are both quiet, i.e. don't give the progress meter. But when I run scp -q host1:file host2:file, I still get the progress meter as well as a Connection to host1 closed. message. The progress meter can be gotten rid of by redirected stdout to /dev/null (although I'd rather not have to), but the connection closed messages comes on stderr, which I definitely want to keep in case there's a real error. How can I make scp quiet? Do I have to run ssh host1 "scp -q file host2:file"?

• Graphic Setup tune-up checklist

  - by Click Ok

  I was trying to play the game Warzone 2100 and the games runs fine, with nice speed, but the screen stays with a horizontal lines "flickering"... My PC have a integrated GeForce Go 6100 vga. Ok, not a powerfull vga, but it's not the end of the world to run a "simple" game like this (compared with another games that ask you send your eyes to purchase a expensive vga). So, I think that the problem can be of the configuration of my machine. I use it in first instance for programming jobs, so I underpay attention to video setup. I would like about a checklist to know if my PC is "ready" to games. By example, I know that I need: Lastest vga drivers Updated DirectX and OpenGL What you suggest? There is too some good programs to test performance and suggests improvements in the system? Thank you! PS: I'm using Windows 7

• HP DV5T laptop problems using Adobe in multiple monitors

  - by Rolnik

  I have a dualview arrangement of two monitors that works just fine for 90% of my applications. However, any time I open Adobe Acrobat Reader to the larger monitor, it fails to permit enlarging of the window to fill the entire screen. In other words, it seems Adobe crops the PDF view at about the size of the smaller of the two monitors, despite Acrobat being present in the larger monitor. I'm using nVideo graphics on the laptop, and connecting to the larger monitor through the docking port of a docking station. Any ideas how to get the Acrobat to be aware that it has more screen real-estate and use it fully?
