• How to properly configure personal domain to send emails and pass spam filters? Is email forwarding enough?

  - by ChocoDeveloper

  I'm using my own domain from Namecheap, and another company for the mail hosting for my personal email. I configured my domain to forward *@mydomain.com to the account I was given in the mail hosting company. I can send and receive emails, but I'm wondering if the emails I send are being flagged as spam sometimes. I remember when I used my own mail server years ago, there were mechanisms for my domain to say "this mail server is allowed to send emails as [email protected]", like adding a TXT record or something. So the questions are: Is email forwarding enough? Will mail servers understand that the mail server is allowed to send emails on my behalf? Is there a testing mail server where I can send an email and be told whether it thinks it's spam?

• Dual boot OSX and Windows 7 natively

  - by Phill

  I'm considering getting one of those new fancy Mac Book Pro's with the fancy screens, but after reading some stuff on the internets about running Windows 7 with bootcamp: https://discussions.apple.com/thread/2770866?start=0&tstart=0 It seems you can't use the integrated graphics with windows, this causes windows to chew the battery life: I am afraid it is not possible. Since Apple introduced dual graphics chip laptops, they kept the low power/embedded GPU hidden under Window and they expose only the power hungry discrete GPU. It feels that this is being done on purpose so that it appears to users that OS X offers a better experience and battery life over Windows. So running bootcamp and windows kills the battery, running in parallels means you don't get accelerated 3d support (or something along those lines), so you don't get the performance out of it. I'm wondering: Is it possible to natively dual boot Windows 7 on a MBP, and if so would/does that give windows access to the integrated graphics to be able to not rape the battery?

• Using Automator to click on an Application-specific button

  - by Roberto Aloi

  I'm new to Automator. I need to launch a specific application and to click on one of its buttons. I've used the "Watch Me Do" feature to register the button click but, in the Automator events log, this action is being reported as "Bring the window XXX to the front." I'm then wondering if a better way exists to "record" a button-click. The reason behind my question is linked to this: http://superuser.com/questions/148386/mac-running-an-automator-task-at-night In fact, using the "Watch me do" approach, Automator is apparently not able to perform the click action when the machine is on sleep and a password is required. Any help would be much appreciated. Thanks.

• Navigating nested RDP sessions

  - by U62

  Often at work I have to RDP into one server in order to get to another. And no, there's no chance of the network getting sorted out such that I can connect to all machines directly :) I'm wondering if anyone has any good tips/tricks for working in this scenario. I tend to open RDP sessions full screen, so the way to get back to my desktop is to click the minimize or restore buttons on the toolbar the drops down from the top of the screen when you are using a full-screen RDP session. The problem is that when you log into A and then from there log into B, A's toolbar covers B's, so there's no easy way to get back to the desktop of A without logging out of B. At least as far as I can see. Maybe there's a keyboard shortcut that can pop you out of the innermost session? At the moment, I try to not use full screen mode on the nested session, but apart from having to remember to set that before I connect, it reduces the workspace and is something I'd like to avoid.

• How do I make Home / End keys behave Windows/Linux like in Terminal.app on Mac OS on Mac Pro laptop?

  - by Nick Gorbikoff

  Hello. I was wondering if somebody knows how to use home/end keys behave in a Windows/ Linux fashion. What I mean is that when I press Apple + Left (Home combo on a mac book pro laptop) it should go to the beginning of the line, and Apple + Right to the end of the line. Right now they change focus to the top of the scroll history. Drives me crazy. Home / End keys behave as expected in TextMate and such but not in terminal, which makes me think it's that app specific. I found some page saying that I need to remap key bindings but I can't do that on every mac i touch. So is there another shorcut in Mac I can use or how do I make Home/End keys behave as expected? Thank you

• Changing The Text Selection Shortcuts on a Mac

  - by Berk U.

  I've recently switched over from a PC to a Mac and I'm wondering if there is any way to edit the text selection/deletion shortcuts on a Mac. I write a lot of code and I've found these shortcuts to be very helpful. Here is a quick overview of the deletion shortcuts (http://lifehacker.com/5803041/the-mac-os-x-delete-key-it-goes-both-ways); the selection shortcuts on the mac are similar, except that you can use arrow keys instead of delete. I'd be happy to learn of any method, though I would much prefer it if someone can come up with a way to do it using KeyRemap4MacBook.

• Is Centos legal?

  - by Jim B

  I'm trying to figure out if centos is legal (or simply grey). Here's what makes me wonder: They seem to go to great pains not to mention that they are based on redhat in the FAQ they mention a policy about using the redhat trademark, but the link no longer exists. When installing it it's not hard to find a lot of redhat code. I don't bother much with the linux world anymore but I had a client that was wondering about it as his auditors picked up on it and wanted to know where his license was.

• Is there any descent open-source search engine solutions?

  - by Nazariy

  Few weeks ago my friend asked me how hard is it to launch your own search engine service with list of websites that suppose to be crawled time to time. First what come at my mind was Google Custom Search however pricing policy is quite tricky and would drain your budget if you reach 500K queries per year. Another solution I found here was SearchBlox, which can be compared to Google Mini service. It's quite good solution if you planing to cover search over small amount of websites but for larger projects it is not very handy. I also found few other search platforms like Lucene, Hadoop and Xapian which seems to be quite powerful solutions to reach Google search quality, and Nutch as a web crawler. As most of open-source projects they share same problem, luck of comprehensive guidance of usage, examples and it's expected that you are expert in this subject. I'm wondering if any of you using this solutions, which of them would you recommend, and what should I be aware of?

• "tar -cfz" versus "tar cf - | gzip": are they different? (or how to improve a backup)

  - by I'm Dario

  I want to speed up my backup done with "tar -cfz", the common way to do it. But day by day my backed up files grow so it becomes slower. I was thinking to take advantage of the several cores available in my server and I was wondering if there is any difference between doing the backup with "tar -cfz" or piping tar to gzip ("tar cf - | gzip"). I guess that there isn't any difference, because the first spawns two processes (tar and gzip), in a similar way like piping it. If there is not difference, do you know any good alternative to do this, without going incremental? I'm looking at pigz too and it looks fine.

• Allowing Remote Connection in IIS on Windows 7

  - by GiddyUpHorsey

  I'm trying to give access to a website in IIS on my Win 7 machine to another person on my network. He's unable to access it. I was wondering if perhaps it was because IIS isn't configured to allow remote connections (I seem to remember having to do this sort of thing on Win XP). I've hunted around in IIS and googled but am not finding a way to configure remote connections on Win 7. Some of the answers I've found seem to refer to Win Server 2008 and talk about a management service in IIS Manager, but it doesn't appear to be present on my machine.

• Using Apache / Kerberos / Keytab to Authenticate Redmine Users Against Active Directory

  - by David Kaczynski

  Please bare with me, as I am still fresh to these technologies. We have a Debian (squeeze) server to which I have root access. It is running Apache, and Redmine is deployed to the server (currently using a local MySQL database for authentication). Apache is configured to use Kerberos and a keytab file to authenticate users against Active Directory. With the current configuration, as soon as a user attempts to access anything over https, the user is prompted for a username / password, which is successfully authenticated against Active Directory. I understand (somewhat) that Redmine has its own LDAP configuration that can be used to authenticate users against an existing Active Directory, but this would require the user to enter their credentials one time for Apache and then a second time for Redmine. I am wondering, Can I somehow configure Redmine to share the Apache authentication method as opposed to requiring the user to enter their credentials a second time? (Using Apache to authenticate against Active Directory is a requirement for a separate application on the server)

• Program complains not enough disk space even if the disk space exists

  - by user1189899

  I have an EXT3 partition mounted in ordered data mode. If a power failure occurs when a program is creating files on that partition, I see that space usage reported is normal and I don't see any partial written files. But when I try to run the same program again after the system comes back up it complains that there is not enough disk space. Even though the free space reported is far more than required. The program always succeeds in normal conditions. Also the problem seems to disappear when the partition is remounted. I was wondering what could be the right way to handle the situation other than unmounting and remounting.

• What type of VPS stats should I look for?

  - by Dave

  I have a few websites that average a total of 10,000 uniques a day across my network. I also have a few mobile apps that pull xml data maybe 5,000 calls a day. My sites aren't anything major just a few wallpaper websites and few other small sites, nothing real database intensive. I currently own a dedicated server and I feel like it's overkill for my network. I'm looking into getting a Virtual Private Server (VPS). I was just wondering what kind of stats I should be looking for to support my network of sites. Thanks

• Hard Disk Space Changes

  - by Write.

  I am currently running on Windows 7 x64, and have observe that my hard disk space is acting a little weird. Currently, my harddisk has 3 partitions, C:, D:, E:. Previously, before I delete a huge folder (30gb of data) from my D: drive, my C: drive has about 1gb left, while my E: drive has about 5 gb left. After deleting the 30gb of data (from D: drive), my space in D: drive has been recovered (but not sure if it's fully recovered), my C: drive which only had about 1gb left increased to 3. While my E: drive which had 5gb left dropped to 1. I was wondering if it has something to do with the fragmentations and whatsoever I always hear about in harddisk. Has anyone encountered similar issues or have an explanation to why it could be happening?

• How secure is the encryption used by Microsoft Office 2007?

  - by ericl42

  I've read various articles about Microsoft's Office 2007 encryption and from what I gather 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi-sensitive documents as long as they use AES and a strong password. Thanks for the information.

• Can I trust that ZFS is consistent between Linux and FreeBSD?

  - by iconoclast

  I'm planning to build a FreeNAS box sometime soon, but if ZFS on Linux eventually proves to be reliable, I might want to switch, just to have a more familiar OS. So I'm wondering if I can trust that the different implementations of ZFS are compatible. In other words, if I just swap out the boot disk from FreeNAS to Linux or OpenIndiana, can I trust that nothing bad will happen to my data? This may seem like a stupid question--obviously it ought to be compatible--but I'm guessing that ZFS isn't commonly used in cases where drives are moved between computers, so I'm hoping someone can provide a better answer than just "it ought to be".

• Disable/enable the proxy on a tab by tab basis in Firefox

  - by Rich

  Is it possible to disable/enable the proxy connection on a tab-by-tab basis in Firefox? I can access the internet with the proxy enabled, and I can access our internal servers with the proxy disabled, but neither configuration allows the other. I have a feeling that Firefox 4's per tab profiles may permit this, but was wondering whether there was a way to achieve this on Firefox 3.6.13, perhaps through the use of an extension. For the moment I'm making do with quickProxy (not QuickProxy which I've just discovered while trying to find quickProxy) which allows me to switch the proxy on and off for the whole browser, but would prefer something more fine-grained.

• Postfix dynamic smtp_helo_name

  - by William

  I have a mail server that relays e-mails for two different domains. I want the smtp_helo_name to be different based on the domain. I'm assuming there is no way to do this via checking the mail headers, so I was wondering if there was a way to do it by sending mail for one domain to one IP, and mail for the other to another. I tried modified master.cf to do this: localhost:smtp inet n - n - - smtpd ip1:smtp inet n - n - - smtpd ip2:smtp inet n - n - - smtpd -o myhostnamee=example2.com And setting smtp_helo_name to $myhostname in main.cf I also tried doing -o smtp_helo_name instead, neither work. Any suggestions would be great. Thanks

• Do superuser's prefer business grade or consumer grade PCs?

  - by joelhaus

  Having burned through a number of consumer grade laptops in recent years, I'm wondering if the additional cost of a business grade computer is a worth while investment. I'm considering getting a laptop with slightly lower specs to justify the added cost. The primary benefits I see are: (i) the notebook will be more reliable, (ii) have a longer life and (iii) the warranty (parts and labor) will be 3 years instead of 1 year. Are there any other considerations one should keep in mind when shopping for a business grade PC? Is purchasing direct from the manufacturer wise or are there other options that should be considered too? Thanks in advance!

• Intel mobile CPU power consumption at idle levels?

  - by Ivan Petrushev

  I was wondering if someone has observations (or specifications) of different mobile processors power consumption levels when idle? Let's define 'idle' with 'browsing web sites trough wifi, no flash, no multitasking'. There are different series processors, recognizable by their first letter. The letter tells about the maximum TDP. For example: T - 30-39W P - max 25W L - 12-19W U - <12W However this is about maximum consumptions during load. Is there any difference in power levels when the CPU is idling?

• Cisco asa 5505 locks up / unresponsive

  - by Chris

  We have a cisco asa 5505 that's new (in service for about 2 months) running 7.2(4) software. Every day around 10a it locks up for approx 10 minutes. We're monitoring it via snmp with stg, and snmp doesn't respond during that time. There's no output in the 'show crash' output. Internet connectivity is also dropped. Wondering if anyone else has seen this and what the fix might be. Currently we're looking at upgrading software, but will need memory upgrade for that. We've forced the speed and duplex on the internal and external interfaces, but the problem is still occurring. It's connected on the internal lan to a netgear 724 gige switch.

• Won`'t read Unicode characters over NFS mount ?

  - by Julz

  Hello, I'm getting this strange issue when trying to play mp3's containing unicode characters ( accents ) over an NFS on OSX, it's all good over AFP, but I'm setup with NFS because it's a linux server on the other end . This is my disk utility setup : nfs://192.168.1.112/Music advanced mount parameters : -P , nolocks nosuid The strange thing is that I can see those files in the finder ( with the accents .. ) but I cant play them !! So Im wondering if it's an unicode issue, since I can see the files properly or a permission issue since I can't play them, but them it wouldn`t make sense that I can't play ONLY the files containing accents .. help ?? Thanks

• Bash Script to Back Up Backs Up Itself

  - by Jay LaCroix

  I have the following bash script that creates a tar.gz of my filesystem on a Kubuntu PC. The problem is, that it also tries to backup the tar.gz backup file, even though I am storing the backup in /tmp and omitting /tmp from the backup. I am wondering why it's backing up the file in /tmp even though I told it not to. #!/bin/bash # init DATE=$(date +20%y%m%d) sudo tar -cvpzf /tmp/`hostname`_$DATE.tar.gz \ --exclude=/proc \ --exclude=/lost+found \ --exclude=/sys \ --exclude=/mnt \ --exclude=/media \ --exclude=/dev \ --exclude=/tmp \ --exclude=/home/jlacroix/Desktop \ --exclude=/home/jlacroix/Documents \ --exclude=/home/jlacroix/Music \ --exclude=/home/jlacroix/Pictures \ --exclude=/home/jlacroix/Projects \ --exclude=/home/jlacroix/Roms \ --exclude=/home/jlacroix/Videos \ --exclude=/home/jlacroix/.VirtualBox\ VMs \ --exclude=/home/jlacroix/.SpiderOak \ / scp /tmp/`hostname`_$DATE.tar.gz jlacroix@Pluto:/share/Recovery/Snapshots sudo rm /tmp/`hostname`_$DATE.tar.gz

• Access Denied on a Drive where All Users list have been deleted in Security Tab

  - by darkstar13

  Hi All, (System is Windows 7 x64) I wanted to restrict access of other people in a certain drive of my computer (Harddisk 1 is partitioned to C & D; I want to restrict Drive D). What I did was go to the Security Tab (under Drive Properties) and remove the All Users entry. My account is an administrator account. I left only Systems and Administrator on the list. However, when I tried to access drive D, I got an Access Denied error, and Security Tab is already missing. I tried to edit Local Group Policy; it does not work. Take Ownership is not available for the Drive as well, but I see it enabled if I select files / folders. Please help. Thanks. Also, I am wondering why, as an Administrator, have my access to that drive denied.
