  • Exclude localhost from htt_proxy

    - by Chilloutman
    I'm trying to access a server that is running locally on my machine (localhost). I'm using the "wget"-command to download the servers http-response. I've also tried using the "curl"-command to do this, but both (wget and curl) are trying to get through my proxy-server and failing at it: --2010-05-04 09:05:34-- http://localhost:8080/api/getplist ... Proxy request sent, awaiting response... 503 Service Unavailable 2010-05-04 09:05:35 ERROR 503: Service Unavailable. Obviously they shouldn't need to go through the proxy, right? So I disabled the http_proxy: export http_proxy="" And then it worked fine. Disabling the the http_proxy every time or permanently are no options. How can I set it to ignore the proxy settings when accessing "localhost"?

  • Java Program Compilaton on Windows [closed]

    - by Mc Elroy
    I am trying to compile my program on the command line on windows using the java command and it says: Error: could not find or load main class or addition class It is for a program for adding two integers. I don't understand how to resolve the problem since I defined the static main class in my source code here is it: //Filename:addition.java //Usage: this program adds two numbers and displays their sum. //Author: Nyah Check, Developer @ Ink Corp.. //Licence: No warranty following the GNU Public licence import java.util.Scanner; //this imports the scanner class. public class addition { public static void main(String[] args) { Scanner input = new Scanner(System.in);//this creates scanners instance to take input from the input. int input1, input2, sum; System.out.printf("\nEnter First Integer: "); input1 = input.nextInt(); System.out.printf("\nEnter Second Integer: "); input2 = input.nextInt(); sum = input1 + input2; System.out.printf("\nThe Sum is: %d", sum); } }//This ends the class definition

  • Is there a postfix mysql virtual_maps append_at_origin workaround so I can pipe to external scripts?

    - by FilmJ
    I am using virtual domains, and I'd like to setup the server to alias to custom scripts. I manage all accounts using postfix mappings to mysql. It seems that postfix automatically appends a virtual domain regardless of how the forwarded/aliased result comes back. So even though i have: "|/bin/command" postfix is reading it as: "|/bin/command"@mydomain.com Is there any work-around, or setting I can fix? It would seem than append_at_myorigin=no would be ideal, but that's unsupported according to the documentation. Another option, maybe I can skip virtual aliases altogether and use the "/etc/postfix/aliases" table - assuming all emails go to the main domain. I'll try this, but if anyone has any other ideas how to make it work with virtual domains, please let me know as this would be very useful! Thanks.

  • Managing TFS Workspaces

    - by Enrique Lima
    You are the administrator (or since you may be the one that knows the most about it) and you need to do some cleanup on what is connected and perhaps even cleanup after people that have left the organization and left some code checked out in their workspace. What permissions do I need? You will need to have Administer Workspaces permission to perform the following tasks. The commands. In order to execute the commands, you will need to open a Visual Studio Command Prompt, once there you will be able to use the tf command.  This has a nice set of options, which I will be providing a listing for later on in another post. To list all workspaces registered: tf workspaces /collection:<url to your TPC> <workspace>;<owner> To delete a specific workspace: tf workspace /delete /server:<url to your TPC> <workspace>;<owner> If for any reason a workspace has embedded spaces, then surround that with “” (double quotes).

  • Virtualbox errors out when creating or opening VM

    - by user106986
    I installed Virtual-box about a week ago and now every time I either try to start a VM or create a new one I get the error listed below. I am in the vboxusers group. I completely uninstalled and re-installed the application without any change in the error. When I run the command below I receive "command not found". Then when I try to install dkms they systems says it is already installed. Right now I have removed the application and any files and would love to re-install the application again to get it working. I remove the application using: sudo apt-get remove virtualbox* --purge Any ideas? Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

  • Ubuntu 13.04 can only work in recovery mode

    - by zhangyangyu
    I have just updated my 12.10 to 13.04. Everything is updated. But I can only boot to a black screen. I mean after the GRUB interface and purple screen. And I can hear the voice of the password interface. But it is only the black screen. It all works OK in 12.10. But it can work in the recovery mode. I mean go into the recovery mode and choose resume. And then everything is OK. But when loading kernel, the screen is dirty. I don't know why and I have Googled a lot. But no resolutions works. My graphics card is Intel GMA HD 4000, tested as VESA: Intel® Sandybridge/Ivybridge Graphics. I have been trapped in this for a whole day. I do need help. Hope someone can help me. By the way, the kernel is 3.8.0-19 if it helps.

  • Restarting Nagios Using PHP

    - by X-Ware
    I am making a tool that is interacting with NAGIOS where some config files should be added so a restart will be needed. What I need to know is how to restart NAGIOS using PHP code since this tool is written in PHP .. when I try to do this using: shell_exec("service nagios restart"); changes do not take place but when I do this manually by the console all changes I did using the PHP script are applied ... after 2 minutes research I found that I am asking linux to execut this command while I am logged in as apache user so I changed the command to: shell_exec('echo "mypass" | sudo -S service nagios restart'); still having the same problem ... new config files are not read until I restart manually any suggestions will be appreciated :)

  • using sed to replace two patterns within a larger pattern

    - by Hair of the Dog
    Using sed how could I replace two patterns within a larger pattern on a single line? Given a single line of text I want to find a pattern (Let's call this the outer pattern) and then within that outer pattern replace two inner patterns. Here's a one line example of the input text: Z:\source\private\main\developer\foo\setenv.sh(25): export 'FONTCONFIG_PATH'="$WINE_SHARED_SUPPORT/X11/etc/fonts" In the example above the outer pattern is "/^.*([[:digit:]]+):/" which should equal "Z:\source\private\main\developer\foo\setenv.sh(25):" The two inner patterns are "/^[A-Za-z]:/" and "/\/". Another way to phrase my question is: Using sed I know how to perform replacements of a pattern using the "s" command, but how do I limit the range of "s" command so it only works on the portion of the input string up to the "(25):"? The ultimate result I am trying to get is the line of text is transformed into this: /enlistments/source/private/main/developer/foo/setenv.sh(25): export 'FONTCONFIG_PATH'="$WINE_SHARED_SUPPORT/X11/etc/fonts"

  • What is meant by "no password set" for root account (and otthers)?

    - by MMA
    Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

  • non-interactive ssh sudo... prompts for the password in plain text

    - by Iain
    I'm running some non-interactive ssh commands. The ssh authentication is taken care of fine through the ssh agent, but if I run a command that requires sudo then the password prompt in my terminal is plain text. For example: ssh remotemachine "sudo -u www mkdir -p /path/to/new/folder" will prompt me for the password in plain text. Does anyone know how I can get it to use the normal secure prompt or that I can pass the password via a switch? (as then I can set up a secure prompt on this side before I send the command) Any help is much appreciated.

  • Vote for bugs which impact you!

    - by Sveta Smirnova
    Matt Lord already announced this change, but I am so happy, so want to repeat. MySQL Community Bugs Database Team introduced new button "Affects Me". After you click this button, counter, assigned to each of bug reports, will increase by one. This means we: MySQL Support and Engineering, - will see how many users are affected by the bug. Why is this important? We have always considered community input as we prioritize bug fixes, and this is one more point of reference for us. Before this change we only had a counter for support customers which increased when they opened a support request, complaining they are affected by a bug. But our customers are smart and not always open support request when hit a bug: sometimes they simply implement workaround. Or there could be other circumstances when they don't create a ticket. Or this could be just released version, which big shops frighten to use in production. Therefore, sometimes, when discussing which bug to prioritize and which not we can not rely only on "Affects paying customers" number, rather need to make guess if one or another bug can affect large group of our users. We used number of bug report subscribers, most recent comments, searched forums, but all these methods gave only approximation. Therefore I want to ask you. If you hit a bug which already was reported, but not fixed yet, please click "Affects Me" button! It will take just a few seconds, but your voice will be heard.

  • How to select a user and remove all groups they are a member of using Powershell (with Quest)?

    - by Don
    I've read quite a bit online about this and thought I had found a solution, but it doesn't seem to be working like I would expect. I am wanting to get a user based on the username I input, then remove all groups that it is a member of. Basically the same thing as going into ADUC, selecting the user, selecting the Member Of tab, highlighting everything (except domain users of course) and selecting remove. Here's the command I'm trying to use: Get-QADUser -Name $username | Remove-QADMemberOf -RemoveAll Others have said online that it works for them, but so far it hasn't for me. It doesn't give an error, it accepts the command just fine, but when I look in ADUC, the groups are still there for the user. Any suggestions as to what I may be doing wrong? Executing from Windows 7 with domain admin rights, Exchange cmdlets and Quest snapin loaded. Thanks!

  • Network(ing) to the Limit

    - by Oracle OpenWorld Blog Team
     By Karen Shamban While Oracle OpenWorld attendees are networking, there's an Oracle Global IT team that builds and maintains the massive networks that help run the show. The objective? To keep things running as seamlessly and smoothly as possible, constantly evaluate priorities, mitigate risk, and be ready for whatever might happen -- because things do happen when there are 50,000 plus attendees, tens of thousands of devices, unexpected requirements, and a constant flow of up-to-the-minute information. Here's just some of what it takes to keep the conference going, network style: 100 Oracle network, voice, and desktop engineers; security, risk management, and other IT experts, who come in from 17 countries  1000+ network switches 300+ miles of copper and fiber 485 wireless access points 2,500 wired laptops 300 VoIP phones And just where are all these networks and devices deployed? This is what the team had to build and manage: Moscone North, South, and West, including: The keynote hall Oracle DEMOgrounds in the Exhibition Halls Hundreds of session rooms Connection Centers, Social Avenue, Lounges Registration The Howard Street Tent and Taylor Street Cafe tented venues Oracle Square (Union Square) Yerba Buena Gardens Masonic Auditorium Sessions and demos at 8 hotel venues That's a whole lot of networking going on. And here's the kicker: the team has only 4 days to bring get it all up and running across these many venues, and exactly 12 hours to take it all down once the show ends. The Global IT team puts in the equivalent of 152 24-hour days for set-up, 227 24-hour days of support during the conferences, and then tears it all down in about 20 24-hour days. And in case you were wondering, the planning for next year's Oracle OpenWorld starts ... next week. No rest for the weary.  Now THAT's networking!  So hats off to the Global IT team -- the job ain't easy, but somebody's got to do it, and they do it remarkably well.

  • dist-upgrade broke my insatll HELP

    - by diefuchsjagden
    so I ran apt-get update; apt-get dist-upgrade the upgrade failed and I lost the gui, I have an encrypted /home drive. When I run apt-get * (any command) I have all kinds of errors mostly missing depends and thats because apparently my network stack is gone. I have no NIC if I run ifconfig. It doesn't even show up with lspci If I were to do a "clean" install of 10.04 LTS which is what I had on my on my build, will I lose all my data? BTW I was just using Ubuntu's default encryption to manage the encryption using my PSWD as the key so if I were to use the same user name and PSWD would my data be accessible? I can see my data from command line, when or if Xorg does start it just loads a basic window with nothing but a black X in the middle of the screen which I can only assume is my mouse cursor but it doesn't move! Reddit /r/linux had some ideas none of which worked was, no help. And apparently /r/ubuntu is full of jerks because all they did was ridicule me. If I can get my install back I probably will be switching back to either Slackware or Gentoo. The Ubuntu forums were of no help they had the same suggestion as /r/linux. I am about to just run my back up script to my back up drives and nuke everything else but I'd rather not.

  • Why can't I install MySQL on my computer? [closed]

    - by Bea
    I have read a lot of tutorials, but I am still having problems. What I tried: I downloaded mysql-5.5.9-winx64. All that I read says that I can run Setup.exe, but there is no such file in the download. The other option I know there is, is including \mysql-5.5.9-winx64\bin in the PATH variable and then trying to execute the mysql command. When I do that, the error I get is: ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061) I then downloaded mysql-5.5.9-winx64.msi, which is easier to install, but once I followed the instructions and it was installed, I got the same error executing the mysql command. How can I use MySQL? EDIT: I've now removed everything I installed, and I want to start from scratch.

  • How to deploy Windows-8 Enterprise Apps to other users?

    - by TToni
    Windows-8 (Metro) Apps can be installed using "sideloading", bypassing the Windows store in enterprise environments. In principle this is easy: Once you enabled sideloading (which is automatically done when a Win8-machine joins a domain), you can install a signed appx-Package through PowerShell with the "Add-AppxPackage" command. But there is a catch: The App is only installed for the user who executes the command and there is no "-Credentials" parameter! I can probably solve that problem in my specific scenario, where I deploy a self-developed app through TFS build to a virtual machine with a fixed demo user (by using remote powershell in combination with "Add-Job", which does take a credential parameter and because I know the given username and the password). But that is not true in an enterprise environment, where I want to distribute my App to thousands of users. Cracking all their passwords seems a bit over the top, so what would be the "correct" way to do this? I can't find any useful information from Microsoft about this, but maybe one of you already ran into this problem and solved it?

  • Route using certain IP address

    - by spa
    I have a server with two public IPs. Both IPs are added to eth0 using ip addr add. Now I'd like to contact a server which uses IP address filtering. Only requests are allowed which use the second IP address. Is there are way to set this up using the standard route command in Linux? I guess that's not the case. So the only solution I see right now: Setup a virtual device let's say eth0:0 and bind the second IP address to it. Then I can reference the device in the route command. Edit: I can't use the second IP as primary one easily as this IP is used as failover IP.
