  • Centralize proxy settings for all the application on my workstation

    - by Leonardo
    As a consultant, I used to work at different clients premises. It happens frequently that most of them has specific proxy settings, but not all the application I have installed on my laptop get settings from system preferences, for allowing me to change settings in one place. Some of them bypass system preferences completely, proposing their own mask for entering specific data such as username, host and password. I am looking for a convenient and not much intrusive way to share a common access point on which I could enter data, and maybe persist them. An 'automatic' switching would be ideal, for example based on some network identification, but there's no problem for me to enter data manually. I am not an IT expert, but to explain myself clearly, I am looking for a solution like .pac file is for browsers. Relevant OS I am using are MacOSX and Linux (Ubuntu).

  • Audio and video streaming using Network Simulator in Linux

    - by Parth_90
    I am working on a project which is to show the simulation of streaming of audio and video data in wireless networks. I want to show the simulation that involves a base station, with few wireless stations. The base station should start sending data once it computes a certain value . On receiving the data, each wireless must begin communicating with the base station. I have gone through basic NS-2 tutorials from over here but I am not getting how to go about integrating it with my project. Can anyone tell me how to do it using NS2 or any other network simulator?

  • breaking mdadm raid and moving to NTFS

    - by daveyt
    I'm running Ubuntu 8 something and my data is on a mirrored pair of 1TB disks formatted as ext3, and the RAID is via mdadm. I want to move to Windows 7 (yeah yeah I know but Linux aint doing it for me at the moment) and migrate the disks to NTFS. My plan is: Break the MDADM RAID (by failing one disk logically) Format the 'failed' disk as NTFS Copy data from the RAID array to the NTFS disk (dont care about perms) Install Windows, (new separate non RAid disk) and my data disk is available. I've researched this and it seems the easiest way. I dont have another disk to back up to so I think this is my only way. Can anyone see a better/easier way?

  • Interaction .asp with .swf flash - good on IIS6, bad on IIS7

    - by gial
    Hi, all! I can't make my app work after migration from IIS6 to IIS7. Problem is described below. My app: in my app I use 'flash.swf'. This .swf appeals to .asp, which contains only: Response.write "<myNode>test_is_ok</myNode>" .swf must get it and show "test_is_ok". And it is really ok on IIS6 2003, but on IIS7 2008R2 .swf shows me "undefined". Situation: Separate request from IE to .asp gets "test_is_ok" on both computers. If .swf from one computer appeals to .asp on another - nothing works. If I delete .asp, then .swf also shows "undefined", so I think it don't really appeals to .asp on IIS7. Suggest me, please, something, what can help.

  • URI Scheme, launch program in its directory

    - by ZaKlaus
    I have registered URI scheme for my app. When I open it with "Run.." or in browser, it runs in hosted directory. For ex. Ive opened url in webpage, program's working dir is in browser. What I want? I want to run program test.exe located at C:\data\test.exe and to use dir. C:\data so it could use other data in relative path. so test.exe would access file .\file.txt without using absolute path Hope I wrote it understandable, sorry for bad English.

  • *.example.com wildcard domain can be parsed from a single page?

    - by Sean Kean
    For a domain 'example.com' - what is the easiest way to set up a wildcard dns (*.example.com), hosting, and htaccess/httpd.conf/virtualhost, and script on a page so that: how.do.i.setup.a.site.with.wildcards.like.this.example.com or anything.that.is.given.as.a.subdomain.for.example.com is rendered by a page at example.com/index.html - yet keeps the wildcard subdomain in the URL bar and passes the full URL as a parameter for rendering tags in HTML? An example tag is a Facebook comment: { div class="fb-comments" data-href="http://how.do.i.setup.a.site.with.wildcards.like.this.example.com" data-num-posts="2" data-width="500" } I just opened a hosting account with spry.com and have a VPS running Ubuntu 11.04-x86-LAMP - Essentially, what is the most straightforward way of doing this? Thanks so much. (I originally posted this over on stackoverflow but realize its more of a serverfault question)

  • Linux Live CD for old computer

    - by Joel Coehoorn
    I have a pentium II (that's right, pentium II) with a scant 200MB of ram. This was a high-end workstation in it's day. The machine currently runs dos on a raid array, and I need to pull some data from it. I figure my best chance at this is to use a linux live cd to copy the data to one of our active directory network shares (there is a network card in the machine). Unfortunately, my linux skills are abysmal, so I'm not sure where to get started: Where should I look to find a linux cd that will run well on such an old system Since I'm likely gonna need to be command-line only, what do I need to do to configure the network card and mount the network share via the command line? Bonus points: exact syntax needed to copy and convert the entire volume for use in VMware server 2.0, but really just copying all the data should be enough.

  • USB Flash drive corrupt files - Help needed

    - by Michael
    I have a 16gb usb flash drive with 8gb worth of data that I can't afford to lose. When I inserted it into my pc, inside the folder that I was storing the data I saw unintelligible characters and nothing in there would open. I ran, windows scandisk and the files (unfortunately) disappeared. I can see that the drive's space still appears to be taken up with data, about 8gb. What should I do to recover it? Is it possible? Thanks in advance... Michael

  • mirroring linux server to external usb harddrive

    - by DuPie
    My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

  • Can't access files on external drive after reformatting Macbook Pro

    - by Peter Wells
    I recently had to reformat my Macbook Pro, and imported my account and settings from Time Machine via the Migration Assistant. Everything on the Mac itself is fine, but now I don't have permission to access almost everything on my external drive. A number of folders have the little red 'no access' sign on them and I can't rename or move anything. Looking at the info for these files, it appears that access rights were attached only to my old user account. Is there some way to reassign these files and folders to my new user account? Thanks.

  • SFTP through proxy

    - by aerodynamic_props
    I have a large amount of data on scratch space at computer b that I want to get. In my network I cannot directly connect to computer b (ssh exits with "No route to host"); I must first connect to computer a, and then connect to computer b. I cannot move the data from the scratch space on computer b to computer a because of a disk quota that is imposed on me at computer a. How can I move the data from computer b to my computer in this situation?

  • Email error 'Default email client is not properly installed' after installing Bugzilla 3.6.3 on Windows Home Server 2011

    - by Brian Frost
    I have been using Bugzilla fine on the older 32-bit Windows Home Server and I have now started a migration to the newer Windows Home Server 2011 with a new machine and a fresh Bugzilla install of 3.6.3. All goes well until I try to check out the email action and I get 'Could not perform this operation because the defaulty mail client in not properly installed. Is this a security /firewall issue? I dont know enough about servers to know what to look for, so any help will be gratefully appreciated. Thanks.

  • Speed up file access on home network

    - by kurasa
    I have 2 PCs (Windows 7 Ultimate) and a Mac running Windows 7 using vmware fusion on my home network tied together using WRN1000 NETGEAR Router On one of the PC's I have a set of file (MYOB .myo). These use a data source to access the data in the files. Operations (reading,writing) to the .myo on the PC which hosts the files is fine but the other 2 it is painfully slow/unreliable and I am wondering what I can do to speed this up. Some ideas I have are 1. Turn off the Windows firewall on all the windows installations on the home network 2. Buy another router. Specifically a router which I can connect a USB flash drive on the back where I can put the .myo files and all the PC can access the files from the USB flash drive on the router (does this speed things up?) Any advice greatly appreciated on how I can speed up this access to data

  • Is there an encrypted write-only file system for Linux?

    - by Grumbel
    I am searching for an encrypted filesystem for Linux that can be mounted in a write-only mode, by that I mean you should be able to mount it without supplying a password, yet still be able to write/append files, but neither should you be able to read the files you have written nor read the files already on the filesystem. Access to the files should only be given when the filesystem is mounted via the password. The purpose of this is to write log files or similar data that is only written, but never modified, without having the files themselves be exposed. File permissions don't help here as I want the data to be inaccessible even when the system is fully compromised. Does such a thing exist on Linux? Or if not, what would be the best alternative to create encrypted log files? My current workaround consists of simply piping the data through gpg --encrypt, which works, but is very cumbersome, as you can't easily get access to the filesystem as a whole, you have to pipe each file through gpg --decrypt manually.

  • University Assignment: Datacenter/Networking Infrastructure for Hosting Company [closed]

    - by TCB13
    My university assigned me to theorizing a data center for an Web Hosting company. The company should provide the following services: Shared WebHosting; Dedicated Servers; VPS (Virtual Private Server); The bandwith (as resquested) is limited to 10 Gbps. Is there any good book / other info I can read (max 100 pages) about how to design a good data center for hosting, what are the best practices and what should be done from a (logical) network perspective, what security policies should be implemented and how the data center should be built (physically)? Thank you ;)

  • List/remove files, with filenames containing string that's "more than a month ago"?

    - by Martin Tóth
    I store some data in files which follow this naming convention: /interesting/data/filename-YYYY-MM-DD-HH-MM How do I look for the ones with date in file name < now - 1 month and delete them? Files may have changed since they were created, so searching according to last modification date is not good. What I'm doing now, is filter-ing them in python: prefix = '/interesting/data/filename-' import commands names = commands.getoutput('ls {0}*'.format(prefix)).splitlines() from datetime import datetime, timedelta all_files = map(lambda name: { 'name': name, 'date': datetime.strptime(name, '{0}%Y-%m-%d-%H-%M'.format(prefix)) }, names) month = datetime.now() - timedelta(days = 30) to_delete = filter(lambda item: item['date'] < month, all_files) import os map(os.remove, to_delete) Is there a (oneliner) bash solution for this?

  • Backups of Exchange 2007 SP3 using VSS are abnormally large

    - by Stew
    I have recently implemented Veeam backup and recovery 6.0, and have noted when backing up my exchange server via incremental updates, it is transferring way more data than expected. Backup is incremental, and setup to use VSS. VSS is stable and healthy, according to vssadmin. Exchange 2007 SP3 running on Windows Server 2008 R2, just last weekend I installed the latest Rollup for Exchange. I thought the nightly incrementals were large, but perhaps my users really are sending that much mail so I tested taking one incremental backup, waiting 10 minutes and taking a second. The second incremental backup transfered 5.8GB of data. We as an organization are absolutely NOT putting 5.8GB of data on the mail server every 10 minutes. Are there any other veeam users who have seen something similar? Is my test faulted? Are there other considerations for VSS?

  • Can I use the voice & SMS features of my GSM SIM through my laptop?

    - by i..
    My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

  • iPlanet Authentication provider

    - by Travis
    Good day. I have stepped into project that requires a server migration that would change the means of authentication for our CAC/PKI SSL enabled website. We are using iPlanet 7 and Oracle Directory Server Enterprise 7 as our LDAP server. The situation is that the site is still CAC/PKI enabled, but at the firewall. The information we want to authenticate against is now in the http header. How do I configure iPlanet and LDAP to authenticate against the header instead of SSL? Thanks. Edit, Can this be done with IIS keeping the Directory Server EE LDAP in tact or is the ACL iPlanet only?

  • How do I get a new column from a Sharepoint list into Excel?

    - by Jono
    I've been using Excel to process data from a Sharepoint list for a while now. However, I recently added a column to the Sharepoint table, and when I refresh the data in Excel, I don't get the new column. I perform a lot of calculations based on this data, so creating a new worksheet with the "new" Sharepoint list, moving the calculations and the pivots to THAT sheet is more hassle than I'd like to face. Is there a way to force Excel to display this new column that I've added? Maybe by modifying the connection string?

  • VMware Fusion / New Machine / verify VMs?

    - by drewk
    I just got a 15" MacBook Pro with 8GB RAM, 2.66 i7 and 500GB SSD. Very sweet and fast! My old machine was 2.66 Core 2 Duo. I used Migration Assistant to migrate my old MBP to the new. When I started VMware to run Windows and Ubuntu I got the message first This VM has been moved or copied to a new machine. Did you move or copy it? I answered Copied. Then I got the message this CPU is a different configuration than the machine that created the VM. You may get unpredictable results. I answered Open Anyway. Windows XP, Windows 7, and Ubuntu all seem to work OK, but how can I verify? Is there some form of test harness for a VM? I have had a VM degrade and become unusable with very catastrophic data loss (on Parallels...), so I am a bit paranoid. Thanks,

  • Exchange 2007 Email Address Policies

    - by Ryan Migita
    We have recently upgraded to Exchange 2007 (from 2003) and have noticed the change from recipient policies to email address policies. We have two separate domains (let's call them domaina.com and domainb.com) we receive email for, have email address policies and both email address policies are not applied. In our Exchange 2003 environment, domaina.com was the default email address when we created new mailboxes and due to the migration, domainb is the default (and its email address policy is a higher priority). Now, when we create a new mailbox (or edit existing ones), the primary email address becomes domainb.com. Now the question is, is this as simple as putting the email address policies in the correct order? Do I have to apply both policies? What effect will the above changes make to existing mailboxes? Since we do not have any conditions set on the policies, I assume prior to making these changes, I should force all domainb mailboxes to not automatically update email address based on policy? Thanks in advance!

  • How can I delete current session in Chrome?

    - by Eric
    I'm using Google Chrome and want to delete the current session data on the fly. I can do this on Firefox with the web developer extension, but Chrome doesn't seem to have the same option in their webdev extension. So how can I do this? I realize that session data is stored on the server side and tracked in the browser with cookies. So really, I think what I want to do is delete cookies that are set to live for the session lifetime. Is there a way to do THAT in Chrome? "Delete browsing data" lets me delete all cookies from within a certain time period (for example, the last hour), but that could delete OTHER cookies on the site that I don't want to erase. I just want to delete the cookie being used to track my current session. Thanks y'all...

  • PostgreSQL disaster recovery options

    - by Alex
    My customer has quite a large (the total "data" folder size is 200G) PostgreSQL database and we are working on a disaster recovery plan. We have identified three different types of disasters so far: hardware outage, too much load and unintentional data loss due to erroneously executed bad migration (like DELETE or ALTER TABLE DROP COLUMN). First two types seem to be easy to mitigate but we can't elaborate a good mitigation plan for the third type. I proposed to use ZFS and frequent (hourly) snapshots but "ZFS" means "OpenIndiana" these days and our Ops engineers do not have much expertise in it, so using OpenIndiana imposes another risk. Colleagues try to convince me that restoring from PostgreSQL PITR backup can be as fast as restoring from a ZFS snapshot but I highly doubt that replaying, say, 50G of archived WALs can be considered "fast". What other options are we missing? Is ZFS an only viable alternative? Can we get a fast Pg DB restore time in the Linux environment?
