  • How can I register a custom protocol with xdg ?

    - by julien
    I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

  • Please help, I am losing my data?

    - by 5YrsLaterDBA
    I was trying to remove MSDN Library-January 2002 by using Revo Uninstaller. I allowed it to delelet those leftover registry entries(my fault, i should be more careful and don't do that). Now my machine is almost unaccessible, cannot open that Revo Uninstaller to recovery, cannot open Windows Explorer, cannot run CMD command from run, all executable shortcuts are not work anymore. I guess I have to reinstall everything but how can I get my data out of the machine? It is a Dell laptop with Windows XP. I am afraid if I restart my machine, my machine will not come back anymore. Please help.

  • Windows Server 2008 R2 DNS Server Intermittently Unresponsive

    - by Ablue
    Throughout the day out DNS servers (2x Win 2k8 R2 servers) are unable to respond to requests. The requests that fail are all on the .root zone that are either cached or obtained from 1 of 5 DNS servers we forward to before going to root hints. At first I thought the DNS servers we were forwarding to were flaky. So I added some more in. Currently the forwarding list looks like ISP DNS 1 OPEN DNS 1 ISP DNS 2 OPEN DNS 2 ISP DNS 3 I have tried: Turning off root hints. Set record scavenging to 7 days. Using dnscmd /config /EnableEDNSProbes 0 as per this. Packet capture at the DNS server shows that there is a lot of query responses with server failure between lan clients and the local dns server; it does not appear to be forwarding those requests. So maybe a problem with caching? Anyhow, does anything have anything I can try to get this working?

  • Vagrant - Failed login, ssh not set up

    - by motleydev
    This question is two fold because somewhere in my attempts to solve the problem, I created a new one. First: I was trying to vagrant up using a Vagranfile based on the standard hashicorp/precise32 box. Everything worked up until default: SSH auth method: private key where it would eventually time out. Enabling gui in the Vagrantfile showed that the machine never actually logs in. I can use the standard user/pass and log in from that point but the vagrant up process still remains at that prior status. Here's where my understanding might be a little dim. I've tried setting auth method from the insecure_pass_key to my root ~/.ssh/id_rsa or whichever one I wanted to use. I'm not entirely sure where to put a copy of the public key or my authorized keys file. I've got a .vagrant.d folder in my user dir (I'm on OSX) which seems to contain the box images. I've got a .vagrant folder in my directory with the Vagrantfile which seems to contain the specific machine I am building off of. I've tried pouring over the docs and forums but I seem to be missing a key concept here. And Now: After a host of tips/tricks such as rolling back by VirtualBox install, uninstalling/reinstalling Vagrant and VritualBox several times, when I try to run vagrant ssh-config with a Vagrantfile based on the same hashicorp/precise32 it says that the box is not enabled for SSH. Specifically, this error: The provider for this Vagrant-managed machine is reporting that it is not yet ready for SSH. Depending on your provider this can carry different meanings. Make sure your machine is created and running and try again. Additionally, check the output of `vagrant status` to verify that the machine is in the state that you expect. If you continue to get this error message, please view the documentation for the provider you're using. So now I am slightly up a creek. Any help would be appreciated if not just clarifying a concept. Some pertinent info: I'm on OSX Maverics Due to the fact I'm running a dual HD system with system files on one HD and user files on another, my permissions are a little wonky and VBoxManage will only let me run commands via Sudo - not sure if it's pertinent - but maybe. I have no idea what I'm doing. That part is perhaps more important.

  • how to split a pcap file into a set of smaller ones

    - by facha
    I have a huge pcap file (generated by tcpdump). When I try to open it in wireshark, the program just gets unresponsive. Is there a way to split a file in set of smaller ones to open them one by one? The traffic captured in a file is generated by two programs on two servers, so I can't split the file using tcpdump 'host' or 'port' filters. I've also tried linux 'split' command :-) but with no luck. Wireshark wouldn't recognize the format.

  • How to automatically save sessions with multiple windows in FireFox

    - by Matthew Talbert
    I've used primarily FF's built-in session management until recently. Now my needs have become more sophisticated. What I want is to be able to have two windows, one with a fixed set of tabs (approximately 5) and the other with "automatic save". That is, when I start FF, I want 1 window to open with my 5 tabs, and another to open with whatever I had when I shut down FF. I've installed "Session Manager", but I can't seem to get it to do what I want. It will save one window, but when I close one window, it removes that one from the session. Any suggestions to do this with either Session Manager or another plugin would be great.

  • Window Servers 2003 Security After Support Lifecycle

    - by Daniel Fukuda
    Hello, I wanted to ask if let's say that Microsoft has stopped supporting Windows Server 2003 now so there is no any security updates and I use that system for Domain Controller (Windows XP/7 Professional Clients) and File Server only + I'm using ESET NOD23 AntiVirus. Will my system be secure? I'm asking because I don't surf internet on that system nor I will install/open any programs/documents and that server is connected to router without any open ports. "On July 14, 2015, all Windows 2003 support, including security updates and security-related hotfixes, will be terminated."

  • How to set printer permissions using PowerShell / some other script?

    - by Borek
    I need to update printer's permissions in a script, i.e. do the same as I would manually do this way: Open Devices and Printers applet Double-click the default printer (open its queue) Go to Printer - Properties In the properties dialog, go to Security tab Change permissions for Everyone (e.g., check Manage documents permissions) How to do that? For example, in PowerShell, I can do Get-WmiObject -class win32_printer -filter Default=True to get the default printer and there are then methods getSecurityDescriptor() and setSecurityDescriptor() but for instance this command: (Get-WmiObject -class win32_printer -filter Default=True).getsecuritydescriptor().Descriptor return null so I'm not sure if I'm doing it the right way. Does anyone have a working example to set printer permissions? Am I on the right path or should I use something other than WMI entirely? Thanks.

  • How to stop receiving an error reading iCal invitations on Mac sent from Thunderbird?

    - by Matthew Rankin
    When I open an iCal invitation (Mail Attachment.ics file) in Mac Mail.app sent to me from someone using Thunderbird, I receive the following error: The only solution that I've found to date is to save the Mail Attachment.ics file somewhere like the Desktop, open it in a text editor, and delete the blank lines at the beginning and end of the file. This problem appears to only happen when I'm receiving invitations from people using Thunderbird under Windows. Does anyone know of a better way to solve this problem? Is this a bug in Apple iCal, or is Thunderbird not meeting the iCal spec? Configuration Information OS: Mac OS X 10.6.2 Mail Program: Mac Mail.app ver. 4.2 (1077) Calendar Program: Mac iCal.app ver 4.0.1 (1374)

  • Run Rails server on client's local machine for single tenancy [on hold]

    - by rigyt
    We are building a Rails application for a client that wants to run the app locally to be close to their data center for best performance. I had assumed we would use a standard web host. What requirements should we demand of the client's infrastructure..all I can think of so far is remote access for developers and a Linux machine? We don't have server admin expertise so would need to contract this, I doubt the client has the expertise. Does this sound like a recipe for disastor?!

  • Process limit for user in Linux

    - by BrainCore
    This is the standard question, "How do I set a process limit for a user account in Linux to prevent fork-bombing," with an additional twist. The running program originates as a root-owned Python process, which then setuids/setgids itself as a regular user. As far as I know, at this point, any limits set in /etc/security/limits.conf do not apply; the setuid-ed process may now fork bomb. Any ideas how to prevent this?

  • Opening an oracle database crashes the service

    - by tundal45
    I am experiencing a weird issue with Oracle where the service started fine after a crash. The database mount went fine as well. However, when I issue alter database open; command, the database does not open, gives a generic cannot connect to the database error & crashes the service. Oracle support has not seen this issue before so it's pretty scary. The fact that there are no logs that give any leads as to what could be causing this is also scary. I was wondering if good folks over at Server Fault had seen something like this or have some insights on things that I could try. It's Oracle 10g running on Windows Server 2003. Thanks, Ashish

  • 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.

  • Splunk is fantastically expensive: What are the alternatives? [closed]

    - by samsmith
    Possible Duplicate: Alternatives to Splunk? This has been discussed, but it has been several months, so it may be time to revisit it: Earlier discussion RE Splunk alternatives For the record, Splunk rocks. But the pricing is simply beyond what we can consider (When I spoke with Splunk today, the cost for a system to index 5gb/day of data is over $30,000.) That is more than we spend on SQL Server (by a large multiple), more than we spend on a rack of servers (by a multiple), etc. etc. The splunk sales team is correct (that for $30K we get more value and functionality than if we spend the same building our own system), but it doesn't matter. The splunk cost is simply too high (by a multiple). Soooooo, we are looking around! Is anyone out there building a splunk like system? Our basic need: Able to listen for syslog messages on multiple udp ports Able to index the incoming data in an async way Some kind of search engine Some kind of UI An API to the search engine (to embed in our console) We currently need to index 3-5gb/day, but need to be able to scale to 10gb/day or more. We do not need a lot of history (30 days is fine). We use Windows 2008 and 2003 servers. Thanks for your thoughts! UPDATE: We spent two weeks researching commercial and open source options. Our conclusion: Write our own (we are a software company... we know how to write things). We built a great system built on mongodb and .NET that gives us the functions we needed from MongoDB in about one engineering week. We have now completed our implementation. We use two Mongodb servers (master and slave), and are able to log and index any amount of log data (5gb/day, 15gb/day, etc), limited only by disk space. OBSERVATIONS: This space needs a solid solution that is $1000-3000 flat rate. The licensing models used by the commercial firms are based on a "milk the data center ops guys" models. That is their right (of course!), but it leaves a HUGE space open for someone to come in underneath them. My guess is that in another year or two there will be a good open source solution that will be really usable. Thank you all for your input (even if it was self promotion).

  • Why are certain default application associations "locked"?

    - by H.B.
    Edit: As i now have three answers that do not answer the question: This question is not about getting the association to work again. I do not like fighting symptoms, i prefer cures. After associating my MP3 files with MPlayer using the Open with/Choose default program... dialogue i can no longer change that association using said dialogue, the Always use this [...] Checkbox is henceforth always greyed out (Control Panel > Default Programs > Associate a file type or protocol with a program does not let me change it either, it seems to just use the same dialogue anyway). That also happened for MP4s but not for MKVs for example, and if i associate my MP3s with other applications like VLC it does not get blocked. I would really like to know why that is and if i can avoid this beforehand (thankfully i know ways to fix it afterwards already). Edit: Another obervation: The blocking programs (i managed to block it with an association to Visual Studio as well) do not appear in the Recommended Programs of the open-with-dialogue (And the explorer said: "The current program is not recommended, but i won't let you change it, ha!"). Edit: A screenshot as requested: As you can see on the top left (if you know the icon of MPlayer), the file is currently associated with MPlayer. Edit: Ways to fix it (Note: This question is not about fixing it) Using the Default Programs Control Panel > Default Programs > Set Default Programs, select WMP, Choose defaults for this program, check .mp3 This should reassociate the files with WMP and you can create a new association in the explorer. Using the registry (As always, keep your hands off it unless you know what you are doing or if you are fine with accidentally breaking your system) HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > FileExts > .mp3 Here you could for example clean up the open-with-list, and the current default program seems to be saved here as well in the key UserChoice, there you can change the ProgId string to another application, you can associate it with WMP by entering WMP11.AssocFile.MP3 or just pick another application right away. You may need to mess with permissions on the key though, if you cannot change the ProgId value.

  • Visual Studio Paired Editor Panes

    - by Chumpy
    Is there any way to make Visual Studio have "paired" editor panes, somewhat like XCode's Assistant Editor feature? More specifically, I'd like to replicate the XCode feature of having a .cpp file's .h partner be automatically open in an adjacent editor panel. So, when a .cpp file is opened in a text editor panel (let's say, on the left of the screen), its analogous .h file will open in another panel (on the right). That way both can be edited on the same screen at the same time, without the need to manually place both files in their respective editor panes. Hope that makes sense, I'm not really sure what terminology to use in order to search for existing solutions.

  • Starting x11vnc remotely when X server is already running

    - by Madiyaan Damha
    I have a ubuntu linux machine that I have already logged into and X server is running (it is pass the login manager like gdm). I can access this machine through ssh. My goal is to start x11vnc on this machine and attach it to the X server that is already running. When I ssh into the machine and start x11vnc, it says: X11 was unable to open the X DISPLAY ":0", it cannot continue. How can I start x11vnc on the remote machine if I don't have physical access to it and Xserver has already started. The reason I want to do this is because the remote machine has several windows open that I want to work on. Thanks,

  • what might cause a print error in perl?

    - by Mark J Seger
    I have a long running script that every hour opens a file, prints to it and closes the file. I've recently found very rarely, the print is failing, not because I'm testing the status of the print itself but rather due to the fact of missing entries in the file until the system is actually rebooted! I do trap for file open failures and write a message to syslog when that happens and I'm not seeing any open failures so I'm now guessing it may be the print that is failing. I'm not trapping the print failures, which I suspect most people don't but am now going to update that one print. Meanwhile, my question is does anyone know what types of situations could cause a print statement to fail when there is plenty of disk storage and no contention for a file which has been successfully opened in append mode?
