• Accessing local files through an http:// address

  - by RexE

  I would like to access a folder of mp3 files on my local Windows machine through http:// addresses. For example, typing http://localhost:9999/songs/test.mp3 into my browser would play test.mp3, which sits in a specified folder on my C: drive. What is the very simplest way to do this? (Background: a program I'm using wants me to enter the URLs of these files, but assumes they are remote and accessed over http. It doesn't accept URLs of the form file://C/Users.... So, I'd like to give these local files addresses that makes them "look" remote.)

• How to to specify network address for a dhcp client

  - by drecute

  I have setup and configured a DHCP server on a sparc running Solaris 10. Now I want to test the DHCP server by creating a DHCP client on another computer running Solaris 11.

• Ubuntu won't boot, only displays GRUB terminal

  - by Badea Sorin

  I have a problem with my Ubuntu 11.04 installation. I've installed Ubuntu 11.04 from Windows, it worked fine for days, but today it won't boot. When I start the machine, GRUB loads. There is the Windows 7 loader, I select Ubuntu from there and after that, I should see the Ubuntu GRUB menu, where I'd select the mode to boot Ubuntu. However, I can't see that anymore. I directly get to a GRUB terminal. Can anyone help me with this? How would I recover my data or reset the boot loader?

• Major permission repair needed on Mac Os

  - by Luke1111

  I made the fatal error of copying and pasting a sudo command into my terminal without double checking it, here it is. sudo -R mysql / What this does (for those that don't know) is recursively change the owner every file from the root down to mysql!! obviously not what i was intending This has of course played havoc with my system, the first thing i did was the apple permission repair but that only works for files that it has an idea of though it has changed a lot of file ownerships back to root. It seems that many library files are still owned incorrectly, as a lot of problems don't work. What i propose doing as a temporary fix until i can reinstall mountain lion is to recursively set all ownerships that are mysql to Luke. I'm not sure what they should precisely but this is still better than nothing. Is this possible using a shell script? I realise that this won't fix the problem properly and i will have to reformat but i need the machine in a workable state just for this week.

• Windows 2003 - logging off the Administrator account makes web applications inaccessible

  - by Saravana

  Consider a web application installed on a Windows Server 2003 SP2 machine with the admin account. The application is accessible in the server as well as in the network when at least one session of the admin account is logged in. If there are no active sessions of the admin account, the web application is not accessible via the network, nor accessible locally when logged in with another user account. What would cause the web application to be inaccessible there's no Administrator session? Please suggest anything that might help find the solution.

• How to repair Java in Ubuntu after trying to switch to Java 6 using update-java-alternatives

  - by Kau-Boy

  I tried to switch from Java 5 to Java 6 using the "update-java-alternatives" command like explained on this page: https://help.ubuntu.com/community/Java But afterwards I get the following error when I tried to execute java: root@webserver:~# java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I also tried to reinstall the java binaries using "apt-get" but I didn't succeed reinstalling it. I would like to post the "apt-get" errors, but unfortunately I don't know how to print out the error messages in English and not in German. My system is a Ubuntu 8.04 ROOT server.

• How do I modify these VPN connection settings for Xfce?

  - by Dave M G

  I have signed up for a VPN (Virtual Private Network) service, and I configured it for use on my computer that runs Gnome Classic with the following instructions: In Terminal, install openvpn packages with sudo apt-get install network-manager-openvpn. 1. Restart the network manager with sudo restart network-manager 2. Run sudo wget https://www.xxxxxxx.com/ovpnconfigure.zip 3. Extract the files from the zip with unzip ovpnconfigure.zip. 4. Move cert.crt to /etc/openvpn 5. Open the Network Manager on the menu bar. 6. Choose add and select the OpenVPN connection type, and click Create. 7. Enter Private Internet Access SSL for the Connection Name. 8. Enter xxxxxx.xxxxxxxx.com for the Gateway 9. Select Password and enter your login credentials. 10. Browse and select the CA Certificate we saved in Step 3. 11. Choose Advanced and enable LZO Compression. 12. Apply and exit. 13. Connect using the Network Manager. It worked, but now I want to set up access to the same VPN service on another machine that runs Mythbuntu, which uses Xfce as its desktop manager. So every point from 5 on doesn't apply. How can I modify the above instructions so that I can get my VPN service working with Xfce. As a further note, while I can access the Xfce desktop directly if I need to, it's more convenient for me to access it via the command line and SSH from on of my other computers. A command line process would be ideal. (I looked for this, and found instructions only for PPTP access, whereas I need OpenVPN.)

• Nagios: Which services should I monitor on different roles of servers?

  - by Itai Ganot

  I've started working in a new workplace and my first task is to build a Nagios server and configure it to monitor the servers in the network. Since I'm starting from scratch I wanted to hear from you, experienced users, which checks should I configure for each role? For example, there are some basic checks which I run on each Linux machine I monitor: SSH, Ping, Load, Current Users, Swap Usage, etc... Now my question is, which specific checks should I run for a DataBase server, for a Networking Switch, for Httpd servers? (I currently monitor how many httpd processes are running) Thanks in advance

• How to send a pipe with psexec?

  - by Pierre-Alain Vigeant

  I'm trying to execute a pipe on a remote server by using psexec. The command that I'm trying to execute is psexec \\servername DSQUERY USER -name *userpart* | DSGET USER -samid -display Currently, the | pipe symbol get executed locally which is not what is wanted (since dsget does not exist on my machine). I tried to use quote around the whole command psexec \\servername "DSQUERY USER -name *userpart* | DSGET USER -samid -display" but that resulted in psexec trying to run that whole quoted sentence as one executable, which obviously does not exist. How can I pass a pipe symbol to the remote server so that it can execute it?

• Disappearing Windows Explorer pinned items

  - by surfmadpig

  This has happened twice now in three months: After rebooting, ALL the pinned items from my Windows Explorer taskbar jumplist are gone. Also, recent items from Windows Explorer are much fewer, only one or two if I remember correctly. After the first time I re-pinned the items I wanted, but about a month later it happened again. I re-pinned All other pinned items in other jumplists (e.g. Word) are fine and have never disappeared. Googling for the problem showed that ccleaner can affect this, but I personally do NOT use any cleaners or related progs on this machine. I also think that both times it happened it was after a windows update, although I can't recall what kind of update it was. After each time, Little Registry Editor showed invalid references in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs , but I had NOT used it prior to the deletions. Any ideas on why this happens and how to prevent it?

• Windows Server vs Sharing

  - by Mark Lawrence

  Not sure if this is the right place for this question. I have a friend that owns a small business running 3 local machines, that are connected to the internet, and a server that each local machine connects to. He has recently bought a newer server, and by server I mean a Windows Vista box. He wants to use this purely to store data that the 3 local machines can access, kind of like a glorified external hard drive. Im suggesting to fore-go the server option and simply setup sharing on the 'server' box. Interested in hearing any suggestions as to whether the server idea is preferable?

• Umbraco on Windows 7 64-bit

  - by HeavyWave

  I'm trying to install Umbraco CMS on Windows 7 64-bit and I get the following exception: [HttpException (0x80004005): Could not load file or assembly 'ImageManipulation, Version=1.0.2105.41209, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant minimum permission required. The application pool's trust mode is set to 'Full', all the user permissions are just as on other sites hosted on the same machine. I went through all relevant topics on Umbraco's forum, but all advices are about the trust level. How do I fix this?

• Streaming video in Virtualbox jumpy

  - by Kevin

  I am trying to get Netflix to work on my Ubuntu netbook. I know it will not run in Linux so I am trying it in my Win XP virtual machine. It streams the video but the sound and video are out of sync and the video often freezes and jumps. I have tried Firefox, Chrome, and even IE. I am thinking my Atom N455 processor does not work well with virtualization. All other apps in the VM work fine. The only issue is streaming [YouTube is jumpy too].Does anyone know of Virtualbox settings I can try to possibly fix this issue or am I out of luck?

• What determines the time to first ping response in an OS?

  - by Stuart Woodward

  When a server (say Windows, Linux) is rebooted, it will take some time to respond to ping. I'm assuming that the software firewall has to be up before pings will be returned as there might be a setting to disable ping responses. Everyone knows that Windows and Linux have have totally different architectures so lets treat them separately. The answer I'm looking for is "After XXX is running, pings will be returned." It would be helpful to know where in the boot order this is too. i.e. at the start or end. I ask because we get questions from a customer about why it takes so long to respond to ping after creating a Virtual Machine. I'm sure this is just an artefact of the OS boot behaviour.

• Word 2003: Bullet style renamed; is there some way to reverse this?

  - by Margaret

  I have a machine that seems to have had its bullet style permanently changed - I previously was creating a document which had a question/answer format, where the answers were bullet points, so I created a style for them. The problem is, it seems to have stuck. If you click the "Bullet" button, the paragraph is formatted in the style. I've tried deleting the style in Normal.dot, and even deleting the Normal.dot file in the entirely - neither seems to fix the problem. Anyone have any other bright ideas on how to fix it?

• Troubleshooting VMware on Ubuntu

  Summary of different problems while using VMware products on Ubuntu. This article is going to be updated from time to time with new information about running VMware products more or less smoothly on Ubuntu. Following are links to existing articles: Running VMware Player on Linux (xubuntu Hardy Heron) Running VMware Server on Linux (version 1.0.6 on xubuntu) Using ext4 in VMware machine   VMware mouse grab/ungrab problem (Source: LinuxInsight) Upgrading GTK library in Ubuntu since Karmic Koala gives you a strange mouse behaviour. Even if you have "Grab when cursor enters window" option set, VMware won't grab your pointer when you move mouse into the VMware window. Also, if you use Ctrl-G to capture the pointer, VMware window will release it as soon as you move mouse around a little bit. Quite annoying behavior... Fortunately, there's a simple workaround that can fix things until VMware resolves incompatibilities with the new GTK library. VMware Workstation ships with many standard libraries including libgtk, so the only thing you need to do is to force it to use it's own versions. The simplest way to do that is to add the following line to the end of the /etc/vmware/bootstrap configuration file and restart the Workstation. export VMWARE_USE_SHIPPED_GTK="force" The interface will look slightly odd, because older version of GTK is being used, but at least it will work properly. Note: After upgrading a new Linux kernel, it is necessary to compile the VMware modules, this requires to temporarily comment the export line in /etc/vmware/bootstrap.

• Troubleshooting USB Hub on Snow Leopard MacOSX

  - by calmcajun

  I just bought a Belkin F5U701-BLK 7-port USB Hub and when I plug it into my iMac it does not seem to recognize it. Do I need to reboot my machine or install a driver? If I have to install a driver where do I get it from? I tried going to Belkin's website to search for drivers and and support info for the hub but I could not find anything. Edit: The USB hub is powering the other devices but my iMac does not recognize both hard drives.

• Can't find generic USB audio driver for a Samson COU1 USB microphone

  - by user10321

  I am unable to use a Samson USB CO1U microphone on a PC running XP, SP3. When I plug it into the USB port, Windows generates the sound indicating that it has found new hardware, and the green LED on the mic lights. But, it does not work, and the device manager reports that it cannot find a driver after searching. The same mic works on a Vista machine. Samson has no driver on their Web site, and insists that the generic audio driver in Windows should work. (http://www.samsontech.com/PRODUCTS/productpage.cfm?prodID=1810). I cannot find a generic USB audio driver at Microsoft.com. Can anyone help? Larry

• Mac OS X: pushing all traffic through a VMWare VM

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• rsync - how to set/keep directory permissions?

  - by Dylan

  I'm using CwRsync to connect from my Windows development machine to a linux webserver : rsync -avuz -e ./ssh --exclude=".svn" /cygdrive/c/xampp/htdocs/project123/ [email protected]:/home/user123/public_html This syncs my development project directory nicely and fast to the server. But after doing this, all directory properties are reset to the local user 'user123' only, so the website is not available anymore. I need to manually reset those properties. Why is this happening, and how to prevent it? PS. coming from a Windows environment I'm having a really hard time understanding rsync. I copied the above command from some examples... just need to get this one small thing working too...

• Unable to install Kaspersky anti virus 2011 on XP

  - by Guruprasad

  I recently tried installing Kaspersky antivirus 2011 on my XP (service pack 2) . Everytime I try to install through setup file, it initiates and then I get a pop up message saying Windows XP not compatible ( Sorry could no get the complete error message ) there is also options which come up saying "continue anyway" but it wont allow to click as the system gets hung . I also tried to skip from incompatible software by following the instructions on Kaspersky's website by creating a short cut to setup file and modifying the target field in it but still I get the same message. It also asks me to reboot before I install but it is still the same . Does this mean that I wont be able to install this antivirus software on my machine ? I also wrote to the Kaspersky support but seems they will take ages to reply.

• Domain name is forwarding to my localhost, no idea why

  - by Dustin Fineout

  On my local development machine, I have a WAMP setup (Windows Vista Home Premium, Apache 2, MySQL and PHP 5). One of my projects is rehash.dustinfineout.com, which may be related to the problem... For some reason, when I try to visit http://www.rehash.com in a browser, it forwards automatically to 127.0.0.1 loopback/localhost. I discovered this entirely accidentally. I have already looked at the http.conf and extra/httpd-vhosts.conf Apache configuration files and these are not causing it. I also checked the windows hosts file but that had no entries in it either (C:/WINDOWS/System32/drivers/etc/hosts - maybe there is another location I need to check). Any ideas? Just to clarify, rehash.com is NOT my domain.

• What are some efficient ways to set up my environment when working on a remote site?

  - by Prefix

  Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

• Able to ping but does not get the data

  - by Dany

  I am facing a problem in my client server program; when using wireless I can ping but not receive any data. There is a source which receives a streaming request from client via server. This works fine when all the machines are connected through LAN cable but when I put all the computers in wi-fi network, all the machine are able to ping each other but when the client send the stream request to the server the ping request between server and client says destination unreachable. It works all well until the client does not send the streaming request. What might be the issue?

• Upgrade went wrong, laptop essentially 'bricked'

  - by hexagonheat

  I have an old netbook I was trying to upgrade from 10.04 to 10.10. Ubuntu was in the process of upgrading when everything completely froze. I left it sit for an hour but it would not respond to anything. So I powered down the machine and it didn't have the necessary files to run Ubuntu. I went to the terminal and it told me to put in some command that I can not remember to 'rebuild' something. That takes me to now, when I turn on the laptop it comes up with a screen "GNU GRUB version 1.98+20100804-5ubuntu3.3" and has a bunch of options such as: 1. Ubuntu, with Linux 2.6.35-32-generic 2. Ubuntu, with Linux 2.6.35-32-generic (recover mode) etc. (there are like 15 of these with different numbers after 2.6.35 and the word 'generic'. It doesn't seem to matter what I pick, it will go to the "Ubuntu" loading screen with the colored dots but then every time it will freeze and I have to reboot to the same thing. I can't seem to get a terminal prompt anywhere either. Any ideas? I can't think of what to do :(
