• Recommendations for SSD for server and database use?

  - by Tony_Henrich

  SSDs are a new technology and they are constantly improving. A lot of the posts here were posted in 2009 when SSDs where less mature and not as fast. What was recommend back then is probably out of date today because of better options. The SSD is used to hold SQL Server databases. Size is probably 128G. The database is used with a CMS and web server so web pages need to get their data and render as fast as possible. Which modern SSD is recommended for such a use? Is there an SSD better than Intel X-25 E/M in terms of performance/cost? (I am also evaluating cost between : RAM + UPS (semi persistent) vs SSD for same amount of gigabytes. No RAID is involved)

• Directing multiple domains to one server

  - by dtechie

  Hi I would like to host 5 word-press blogs on my unlimited server space i bought from a web-hosting company similar to hostgator. Now the companies say it is technically not possible to direct more than one domain to the hosting package and i would need to buy multiple hosting packages .

• Apache Bench length failures

  - by Laurens

  I am running Apache Bench against a Ruby on Rails XML-RPC web service that is running on Passenger via mod_passenger. All is fine when I run 1000 requests without concurrency. Bench indicates that all requests successfully complete with no failures. When I run Bench again with a concurrency level of 2, however, requests start to fail due to content length. I am seeing failures rates of 70-80% when using concurrency. This should not happen. The requests I am sending to the web service should always results in the same response. I have used cURL to verify that this is in fact the case. My Rails log is not showing any errors as well so I am curious to see what content Bench actually received and interpreted as a failure. Is there any way to print these failures?

• Manipulating Exchange 2003 shared contacts folder remotely

  - by andybak

  I've got a CRM web app running on a remote server that needs to synchronise it's contacts with the in-house Exchange 2003 shared contacts. Exchange 2003 doesn't appear to support web services. What would the typical approach to this problem be? My initial instinct would be to open port 80 on the Exchange server, run a simple webserver, POST to it and then control Exchange via OLE automation scripting (if that's what people are still calling it!) but there might be a better solution I'm not aware of. Any suggestions?

• What is the proper way to set up the Apache document root in terms of privileges?

  - by racl101

  I have just installed Ubuntu 9.10 server edition on my machine and I wish to run my own personal local server with other users in the same LAN. First, I was wondering what folder directory structure is best for the web root? Should I just use: /var/www/ and start throwing web documents there or should I create a folder elsewhere (maybe the home directory)? Second, in the /var/www/ directory only the root user can create documents in there, however, I wish to have other users be able to create files in the document root and upload them via FTP. Should I change the permissions or the www/ folder? Or again, should I create the document root elsewhere with different permissions? What is the safest way of doing this?

• Linux periodically "losing" ability to connect to server via SSH?

  - by gct

  I know this isn't exactly a programming question, but it popped up in my use of git for programming projects at least. I've got a web server that I use to host my git repos on, but my ubuntu box seems to "lose" the ability to connect to it via SSH. I'll get a "connection refused" error when I try to ssh or use git. Rebooting my local machine will fix the problem, but only temporarily. I can still connect to the web interface just fine, and the problem manifests with other servers as well. I've been working around it by pulling my changes over to my laptop and pushing from there, but that's sub-optimal as you can imagine. Has anyone seen something like this? I'd be tempted to say it's some kind of IP caching problem, but I can't connect even using the IP address of the server directly... Running Ubuntu 9.04

• Prevent specific applications from being run as administrator

  - by Unsigned

  Background Most installation toolkits have the ability to launch, automatically or otherwise, external programs after installation. This is often appears in the installer via such options as "Show readme", or "Start program". Issue The problem is, many of these installers are poorly coded, and do not drop permissions appropriately. For example, starting the application automatically, or opening the application's homepage in the browser, often results in launching the application or browser with the installer's Administrative privileges, or a "High" UAC integrity level! This has the potential to open up security breaches, by opening up the installed application, or a web page (and possibly browser add-ons), that are now running with elevated permissions. (This is the reason I strongly recommend never choosing auto-launch options when installing software.) Question The question is: Is there a way to prevent certain applications (such as a web browser) from ever being launched with Administrative privileges, i.e., an automatic drop-privilege?

• IIS doesn't respond to 127.0.0.1 (external IP works fine)

  - by Jordan

  I have an AWS web server - call it box.company.com. It's running IIS and if I visit http://box.company.com in a web browser (from any machine, including box.company.com), it responds correctly with our site. However, if I visit localhost/ or 127.0.0.1/ when I'm logged into box.company.com, I get a "couldn't connect to host" message. The hosts file has only one entry - the standard "127.0.0.1 localhost" line. Pinging 127.0.0.1 works fine. Pinging localhost correctly resolves to 127.0.0.1 and works fine. I've tried restarting IIS and restarting the DNS Cache. I had this problem once before, and restarting the server fixed it, but I'd like to know what's going on in case this happens again in the future.

• Citrix XenApp application does not have keyboard focus when launched

  - by Jason Pearce

  On new or existing Citrix XenApp 4.5 servers, I am having problems streaming the Allscripts Pro EHR application via the XenApp web interface. When users launch the application via the Citrix XenApp web interface, the application does not have focus, preventing users from typing in their username and password. If they use their mouse to select either the username or password fields, they still cannot enter any text. However, if they do any of the following actions, they can then enter in their username and password and the application runs without problems: Click on the Login button with empty fields. Logon fails but they can then enter their credentials. Minimize the login window and then maximize it. They can then gain keyboard focus to enter their credentials. What might be preventing this particular application from having focus when it launches?

• How to copy a button with shadow effect from PSD to PNG

  - by Alex

  I got a web site design in PSD file from a web-designer. All element s there snap to guides, which is handy when I make a selection to copy an element of design to a PNG file: guides make my selection precise. One button there has two states: normal and hover. Both states contains of several layers. So I am trying to copy both states as PNG files in order to make a nice button in html. The problem is that both states have shadow effects, which go beyond the layers' edges, i.e. when I try to select a button my selection (snapped to guides) does not include an outer part of the shadow. How do I make a precise selection of the button state in such situation?

• Windows 8 apps not connecting to internet with USB dongle/modem

  - by Relborg

  The question pretty much says it all. I have Windows 8 Professional 64-bit and my main/only method of getting connected to the internet is to use this USB dongle/modem I have. Now it works perfectly, but when I go into the Windows "store" app it keeps on saying that I'm not connected to the web. In fact this happens for all "apps", they all think I'm not connected to the web when I actually am. Normal desktop applications e.g. browsers run fine. Is this a bug that has still not been resolved or is there some setting I need to go mess with? Thanks in advance!

• Connect to server in VMWare player while host is not connected to a network

  - by blockcipher

  Hello, I have a linux server VM on my host machine using VMWare player and if I'm on a network, I can connect to the web server on the VM via a web browser. However, I tried to do the same while I was disconnected from a network and I couldn't. The networking is set to Host-only and I did use dhclient/ifconfig to make sure that yes, I did have an IP address assigned to the VM. While I can work around this, the purpose of the VM is to allow us to demo our app from any machine and that machine may not be connected to a network. Thanks.

• Java and Sendmail HELO requires domain address

  - by ealgestorm

  I am trying to set up emailing from a java web application hosted on a linux server (Cent OS) in apache. Sendmail is working fine from the command line as root on localhost but when trying to send emails from the java web app (also on the same server from localhost) the following java exception is thrown. 501 5.0.0 HELO requires domain address EDIT: I have read that some people have found this is due to an incorrect hosts entry currently the hosts file contains 127.0.0.1 Centos-VPS localhost.localdomain localhost and i'm not sure what the Centos-VPS bit at the start is for but this is a clients hosted server so don't really want to break stuff EDIT see the RFC is helpful ... 501 Syntax error in parameters or arguments Now I know what the problem is! (note the sarcasm people.)

• Editing remotely the PHP files on a Centos server

  - by Alex2012

  I have a intranet web server (Centos 6, Apache, PHP) to which I would like to give access to a developer. He will connect by remote desktop from Windows 7 to Ubuntu 12.4 and from here by SSH to /var/www/html folder where it has to create and edit the files. This solution was chosen because: - I could not make a remote desktop connection from Windows to Centos - The web developer need some editor for PHP files and is not allowed to install software on Windows 7 machine - it is more a test solution ( we are all learning to use Linux). When the developer is connected from Ubuntu to Centos by SSH (SFTP) he could save the changes only if on Centos the account used to connect has ownership to that folder. Can you please tell how can I give all required rights. I tried different solutions found on Internet but without to much success. Are there other way to connect to Centos server?

• How to make your apache application accessible within network

  - by guest

  I have a Windows XP machine where I have installed WAMP and made a PHP based web application. I can access the web application from within this machine by using the browser and pointing to: http://localhost/myApp/ --- and the page loads fine. Now I want this site (http://localhost/myApp) to be accessible to all machines within the network (and may be later, to the general public as well). I am quite new to this, how do I make my site accessible to all machines within the network and to the general public in the internet? I tried modifying the httpd.conf file in Apache (WAMP) by changing Listen 80 to Listen 10.10.10.10:80 (where I replaced 10.10.10.10 with the actual IP of this windows xp machine). I also tried "Put Online" feature in WAMP. None seem to work though. How do I make it accessible?

• Is it necessary for a Windows Server 2008 R2 to join a domain so that its IIS can communicate correctly?

  - by Jack

  I have a Windows Server 2008 R2 that is not join to any domain. I have developed an web application that will display the domain name and the username on the server itself. However, when I publish my web application to IIS, it always fail and display different types of error messages (because I change settings such as Enabled ASP.NET Impersonation, Disable Anonymous Authentication, Set Application Pool to Classic and so on) So, I was wondering if it is necessary for the Server to join in a domain so that I can reduce any unnecessary error message and be able to zoom into the correct direction?

• Cannot access internal network on OSX 10.6.6

  - by cabuki

  Last week, I began having trouble connecting to our internal web servers. Usually, a refresh would take care of it or switching to a different wireless network, but as of yesterday, this wasn't enough. We have an internal DNS server using dnsmasq and a private internal host name (us.lcl). Once I started having more issues with the names not resolving, I tried pinging the server. Using the internal host name (s1.us.lcl), it failed. I tried using the IP address, but that also failed. I have no problems accessing external sites with the exception of it being a bit slower than normal. A reboot yesterday at lunch time after following the instructions here seemed to fix the issue, but when I came into the office this morning, it had stopped working. As of this posting, I cannot ping, ssh or access the web server using the internal host name or ip address. I'm the only one running 10.6 in my office and none of my colleagues has this issue.

• Why are Full GCs not running on my gcInterval I set?

  - by Brad Wood

  ColdFusion 10 Update 10 Windows Server 2008 R2 Java 1.7.0_21 I am trying to figure Full GCs to run every 10 minutes. I have used the gcInterval JVM arg in the past on earlier versions of ColdFusion with success, but I have confirmed with verbose GC logs that Full GCs are still happening on the hour (Unless the Old Gen gets so full that it forces a full collection).

• IE session (-nomerge) manager

  - by skrco

  I'm looking for an application that can manage (save/open) multiple Internet Explorer instances (to be precise nomerge sessions), host them in single window and arrange these instances e.g. in tabs, so in result you have double tab bar. In functionality it's similar to Remote Desktop Manager, where you can create Web session, but in embedded mode you cannot set the nomerge option. I've been searching the web, but with no results. So I put this question whether anyone know of such application or workaround. Or I have to write my own app.

• How do I pull a backup from a Linux server to my Windows PC using rsync?

  - by Nogwater

  I'm currently using sftp to download nightly backups (.tar.gz) from my web host to my desktop computer. I think I'd like to switch to rsync to minimize the bandwidth (and time). I have cygwin installed on my PC, but don't use it for much. I have shell access to my web host via ssh (PuTTY). Let's say my source directory is myserver.com:/home/username/backups/, I want to grab all of the .tar.gz files from there, and I want to save them to C:\Backups\ locally.

• "Meet in the middle" with SSH

  - by stillinbeta

  I have an interesting question regarding SSH. I have a machine at school that I'd like to be able to access from elsewhere. It's behind a firewall/NAT, so I can't get at it directly. I have a leased web server that I can SSH into from anywhere. I was wondering if I could do some voodoo with port forwarding to get to my machine at school via the web server. I think this comes down to whether you can do SSH "backwards," which may or may not be possible. Basically: Machine A can access Machine B Machine C can also access Machine B How can Machine A access Machine C?

• Is there a way to use something like RewriteRule ... [PT] for an external URL?

  - by nbolton

  I have a non-apache web server running on port 8000, but this cannot be accessed from behind corporate firewalls. So, I would like to use my apache 2 server as a proxy to this other web server. I've tried using: RewriteEngine On RewriteRule /.* http://buildbot.synergy-foss.org:8000/builders/ [PT] ... but this does not work; I get: Bad Request Your browser sent a request that this server could not understand. However, it worked fine with [R]. Update: Also, when using ProxyPass, I get this error: Forbidden You don't have permission to access / on this server.

• Searching Objects on SonicWALL (NSA 2600, SonicOS 6.1)

  - by Justin Scott

  Ok, this may sound like a dumb question, but does the SonicOS web interface not have a search option for object definitions? One of my clients recently decided to replace their Astaro Security Gateways with SonicWALL firewalls. These sit in front of a small data center full of servers and we have several hundred custom service and address definitions that need to be ported. The SonicOS interface provides a basic list for service and address definitions but no search option to be found. To make it worse, there is no option to list them all on one page (they're paginated 50 at a time) so I can't use the text search on the web browser either. The Astaro units have a nice search option on their definitions so perhaps I just got spoiled by their software. Am I missing something or is there some way to search for an object without paging through the list and finding an entry manually?

• Windows 7 Shortdate Format Ignored

  - by Element

  I am moving a copy of an ASP.net web application running on a windows server 2003 box to a Windows 7 Laptop. On the win server 2003 box the locale was set to United States and shortdate format was M/DD/YYYY. On the Windows 7 machine it is DD/MM/YYYY which is breaking the application. I have tried changing all the locale settings under controlpanel-regions to United States and rebooting with no luck. I also tried explcitly setting the shortdate format to M/DD/YYYY under the region settings but the web application seems to ignore it. How can I change the Windows 7 shortdate format so an ASP.net application will recognize it ?

• PPTP VPN Server issue : server = centOS & client = windows 7

  - by jmassic

  I have a CentOS server configured as a PPTP VPN Server. The client is a Windows 7 with "Use default gateway on remote network" in advanced TCP/IPv4 properties enable. He can connect to CentOS without any problem and can access to: The Box of his ISP (http://192.168.1.254/) The CentOS server The website which is hosted by the server (through http://) But he canNOT access any other web service (google.com or 74.125.230.224) I am a beginner with web servers so I do not know what can cause this problem. Note 0 : The Windows 7 user must be able to access the whole internet through the CentOS PPTP proxy. Note 1 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED it is the same problem Note 2 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED AND "disable class based route addition" CHECKED the Win 7 can access google but with the ISP IP (no use of the VPN...) See Screenshot Note 3 : I have made a echo 1 > /proc/sys/net/ipv4/ip_forward and a iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
