  • How do I add permissions via command line for "everyone" on external HDD

    - by acidzombie24
    I have an external HDD and I kind of messed up the file permissions but when fixing it I thought it is ok bc with my username I can access the files perfectly fine. Now that I use this with two PC (actually ATM I don't have access to my other PC) I can't access these files. The problem is this directory has hundreds of folders with no permission for "everyone". I would like to give it the default permissions including have all access for the user "everyone". How do I do that via command line for these hundreds of folders?

  • Mac firewall blocking nginx (port 80) from external side

    - by Alex Ionescu
    I installed nginx using ports and started it with sudo. Accessing the nginx welcome page from localhost works perfectly, however accessing it from an external computer fails. Doing an nmap on the computer from the outside reveals 80/tcp filtered http So clearly the mac firewall is blocking the port. I then proceed to add the nginx executable to the firewall exception list as seen in this image, however the nmap still shows up as port 80 being filtered and I'm unable to access the webpage. The exact binary that is in the list is /opt/local/sbin/nginx which to my knowledge seems correct Any ideas what I should do? Thanks! P.S. Turning the firewall off does allow me to access the website from the outside world, however that isn't an ideal solution.

  • Replicate portion of an LDAP directory to external server

    - by colemanm
    We're in the process of setting up a Jabber server on Amazon EC2 right now, and we'd like to have our internal users authenticate via LDAP so we don't have to create/manage a separate set of user accounts than the master directory in the office. My question is: is there a way to copy, unidirectionally, a segment of our internal LDAP directory (the user accounts OU) to an external LDAP server and authenticate Jabber against that? We're trying to work around having our externally hosted machines out in the cloud accessing our internal network directly... If we can replicate in one direction only a subset of the user accounts, then if that gets compromised we don't necessarily have a critical security breach into our internal network.

  • Path of Replication

    - by geeko
    I'm currently developing a replication system to keep data in-synch between an arbitrary number of servers. Some of these servers exist in one cluster on one LAN. Others exist somewhere else in the world. I'm wondering what are the pros/cons of different paths that we choose to flow replicated data on between servers? In other words, what are the different strategies to load balance the replication process ?

  • Windows 7 RDP Problem - connecting to external zone with computer names

    - by alex
    I recently installed Windows 7, all is well so far, apart from using RDP to access computers outside my domain. We use a datacenter, outside of our domain. I was using Windows Vista before (not sure if this is relevant) - I could RDP no problem to the machines (using their machine names - Web10 for example) I have changed my IP address to be the same as it was when i was using vista We use a draytek firewall - we use DMZ Host to map my IP to an external ip- which is allowed to access the datacenter I've disabled windows firewall When i try to connect in Remote Desktop client, using Web10, I can't connect, however, if I enter the actual IP address, i can. I have run out of ideas... any help is appreciated!

  • No External Sound

    - by Walter
    I have ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal did alsamixer seems to recognize my soundcard, though the driver is not listed in system - admin -hardware drivers, the only driver listed is my graphics card. I have tried several forums and it seems no one is interested in responding to sound issues. Here's hoping it is different here.

  • Set and Verify the Retention Value for Change Data Capture

    - by AllenMWhite
    Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)

  • Application self aware of external database record modifications.

    - by Khou
    How do you make your application aware that a database record was changed or created by an external application rather than the application itself? Do you add a special check sum to the database record or what do you do to stop external changes to the database? (in case it was hacked and the hacker decides to add a new record or change an existing database record)

  • Windows 7 + NVidia == 640x480 on external projectors

    - by ben2004uk
    Hello, I'm having a major problem and I really need your help! I have a MacBook Air which has the NVidia 9400M. The problem is, when I connect it to an external projector Windows 7 (and Vista) only allow me to connect at 640x480. I need it to use the laptop to present at conferences, as such I need it to work on a number of different projectors - at the moment I need to use OSX and VMWare but it's painfully slow and really doesn't work. At the moment, I'm considering buying a new laptop :( Is there any way to override the screen resolutions provided? I've saw some information around EDID? Thanks Ben

  • How can I stop the panel from showing on an external projector/monitor?

    - by hellocatfood
    In Ubuntu 10.10 (and possibly previous versions), when I connected my laptop to an external source (monitor/projector) and set it not to clone my desktop the display on the external source would not show the (gnome-)panel (just a full-screen desktop with no icons). Since upgrading to Ubuntu 11.04 (using Unity) when I now connect the external source has the panel on there. Is there any way to revert to the previous behaviour in 11.04?
