• Microsoft word slow switching and safe mode

  - by huggie

  I don't know what I did, but recently when I opened Microsoft Word document, I experienced very slow app switch between it and other applications. When I start Word in Word's safe mode (as described here http://wordprocessing.about.com/od/troubleshootin1/qt/safemode.htm ), the issue disappears. Now I don't know where to find out which plugins were loaded that's causing the problem. Or where the normal.dot is if that's the problem. I'm on Windows 7 64 bit. Thanks.

• ASUS P6X58D and 12 GB of RAM

  - by Hunter

  I just assembled my new PC and it screams, BUT it's only recognizing 8 GB of RAM in BIOS and OS rather than the installed 12 GB. In the BIOS the RAM was registering at 1066 MHz so I set it to 1600 MHz. I updated the BIOS to the latest non-beta release. http://www.asus.com/product.aspx?P_ID=wurRaDZ8lo4Ckukj OS: Windows 7 Ultimate 64-bit Motherboard: ASUS P6X58D Premium CPU: Intel Core i7 920 RAM: CORSAIR XMS3 12 GB (6 x 2 GB) 240-Pin DDR3 SDRAM DDR3 1600 HDD: Intel 80 GB SSD SATA II Power supply: Kingwin 1000 W Modular I've installed the Beta BIOS 0808 but no luck!

• Apache + mod_php Ignores SUID?

  - by profitphp

  Does apache or mod_php cause a SUID flag to be ignored when using the shell_exec command from a web accessed PHP script? I'm trying to allow a web accessible PHP script to rename some files which the apache user does not have write access to. I don't want to give it access to write these, as I only want one controlled script to be able to do this. I'm trying to avoid SUDO and the config needed or the headache/insecurity of using a que called from a privileged users cron, and it seemed like I should be able to use SUID to accomplish this. If you need more info, I've got a similar question open over here, but I think its too detailed and people are not seeing what I'm asking. http://stackoverflow.com/questions/6432931/suid-issues-with-php-apache

• DRS: Unknown JNLP Location

  - by Joe

  We are using Deployment Rule Sets to limit access to the older JRE to well-known applications like - but are running into a problem. One business critical applications has the following properties (*s to protect info): title: Enterprise Services Repository location: null jar location: http://app.*.com:52400/rep/repository/*.jar jar version: null isArtifact: true The application downloads a .jnlp file, and uses java web start to execute. Since the location is null, this application cannot be targeted by a location rule. And the certificate hash method only works when the application is cached (being ran more than once). If cache storing is off, which is the case in some situations, how can this application be targeted? Or at least told to run with an older JRE on start? This problem is specifically noted in this bug Thanks!

• DNS Server Spoofed Request Amplification DDoS - Prevention

  - by Shackrock

  I've been conducting security scans, and a new one popped up for me: DNS Server Spoofed Request Amplification DDoS The remote DNS server answers to any request. It is possible to query the name servers (NS) of the root zone ('.') and get an answer which is bigger than the original request. By spoofing the source IP address, a remote attacker can leverage this 'amplification' to launch a denial of service attack against a third-party host using the remote DNS server. General Solution: Restrict access to your DNS server from public network or reconfigure it to reject such queries. I'm hosting my own DNS for my website. I'm not sure what the solution is here... I'm really looking for some concrete detailed steps to patch this, but haven't found any yet. Any ideas? CentOS5 with WHM and CPanel. Also see: http://securitytnt.com/dns-amplification-attack/

• I just ordered 70/10 internet service, and need a new router I think?

  - by data_jepp

  Before I had 25/5 service and the N standard router did just fine. Now it doesn't do the job. Online speedtest reads at 82 so I have the line. But my laptop is getting less than 30 in my room. My laptop has the following WiFi card: http://www.intel.com/content/www/us/en/wireless-products/centrino-advanced-n-6205.html What is this talk about 2.4 and 5GHz? Can my laptop be connected at once over both bands? And would that let me use the full 70Mb over Wi-Fi?

• how to print labels from UPS printer on UPS website

  - by paynes_bay

  I have several computers, in my office, that have UPS printers attached to them. On most of these computers if you go to ups.com, login, and print a shipping label out, it prints out just fine. The website somehow selects the appropriate printer and prints to it. It doesn't present a prompt, asking you to select the printer, the number of pages, etc - it just prints it. Only problem: there's one computer on which it's not doing this and I don't know why. I can see the printer in Printers and Faxes and can print out test pages from the Properties tab, so the printer clearly works - it just isn't printing out from UPS's website. Any ideas?

• How to use multiple SkyDrive accounts on one computer?

  - by user1563721

  Is there any way how to use multiple SkyDrive accounts on one computer running MAC OS X or Windows 8? I would like to sync data from different accounts to different folder and not to merge these accounts to one. The reason is that every SkyDrive has it's storage limits and I'm using every account for different work data. The result should be the following: I have a number of SkyDrive accounts every for different work, let's say: S1 S2 S3 I would like to sync exactly the same number of folders on computer using different accounts to sync them: SkyDriveS1Folder - (folder on computer which syncing the content of S1 SkyDrive) SkyDriveS2Folder - (folder on computer which syncing the content of S2 SkyDrive) SkyDriveS3Folder - (folder on computer which syncing the content of S3 SkyDrive) Is it possible somehow? I found a workaround for Windows machines (http://superuser.com/questions/525932/running-multiple-instances-of-microsoft-skydrive) but is there anything for MAC OS X machines? Or is it possible through any third party application?

• How can I express this nginx config as apache2 rewrite rules?

• How to use NTFS-3G installed using MacPort?

  - by Raiyan Kabir

  After upgrading to Lion I'm having problem mounting NTFS drives in read/write mode. This is because NTFS-3G distributed by http://www.tuxera.com does not work with Lion. As far their suggestion I installed NTFS-3G using MacPort. But as far as I can see it does not come with the usual preference pane. Its not enabled by default. Do anyone know how to enable it? Or how to have the Preference Pane for the NTFS-3G from MacPorts.

• Web browser being selective about the sites that it will visit.

  - by Andrew Doran

  I've been trying to help my father-in-law with this problem but haven't been able to get anywhere. Since the weekend the web browsers on his computer (Chrome and Internet Explorer on Windows XP) will only let him get to certain sites - for example, he is able to conduct his online banking but he cannot visit www.bbc.co.uk, www.amazon.co.uk or www.ancestry.com. There is another computer in the house that goes via the same router and this can connect to both, which suggests it is his machine. I tried running a tracert to www.bbc.co.uk and managed to get through, but the web browser hangs with a message that it is waiting for a response. I tried using the WinSockFix tool in case it was anything to do with a recent registry change but that didn't work either. He can't think of anything that he recently did on his machine to cause the problem. Can anyone help?

• proxy/vpn by dns entry

  - by rcourtna

  I've been using a service by unblock-us.com, which provides a proxy to Canadians/others allowing access to services that are locked down to only US ip addresses. This is easy enough to achieve by setting up a reverse proxy (eg: squid) on a US-hosted server, and then configuring your browser or OS to use that proxy. However, there is something that unblock-us does that I'm not sure how to duplicate. Rather than configuring your OS to use them as a proxy, you can simply change the DNS Server settings on your router to point to their addresses. Any requests to services they support are automatically proxied. The advantage to this is that you don't have to set up every computer in your house, and it "just works" with clients like ps3, xbox, android, etc. Disadvantage is you really don't have control over what gets proxied, as well as there are privacy concerns I suppose. How can I achieve this same functionality on my own us-based slice?

• Disable Memory Modules In BIOS for Testing Purposes (Optimize Nehalem/Gulftown Memory Performance)

  - by Bob

  I recently acquired an HP Z800 with two Intel Xeon X5650 (Gulftown) 6 core processors. The person that configured the system chose 16GB (8 x 2GB DDR3-1333). I'm assuming this person was unaware these processors have 3 memory channels and to optimize memory performance one should choose memory in multiples of three. Based on this information, I have a question: By entering the BIOS, can I disable the bank on each processor that has the single memory module? If so, will this have any adverse effects or behave differently than physically removing the modules? I ask due to the fact that I prefer to store the extra memory in the system if it truly behaves as if the memory is not even there. Also, I see this as an opportunity to test 12GB vs. 16GB to see if there is a noticeable difference. Note: According to http://www.delltechcenter.com/page/04-08-2009+-+Nehalem+and+Memory+Configurations?t=anon, the current configuration reduces the overall data transfer speed to 1066 and in addition, the memory bandwidth goes down by about 23%.

• best practice? Consumer data in MySQL on Amazon EBS (Elastic block store)

  - by jeff7091

  This is a consumer app, so I will care about storage costs - I don't want to have 5x copies of data lying about. The app shards very well, so I can use MySQL and not have scaling issues. Amazon EBS has a nice baseline+snapshot backup capability that uses S3. This should have a light footprint (in terms of storage cost). BUT: the magnolia.com story scares the crap out of me: basically flawless block-level backup of a corrupt DB or filesystem. Is there anything that is nearly as storage efficient as EBS at the MySQL level?

• Trying To Uninstall Exchange 2007 From Server - Stuck On "Mailbox Role Checks"

  - by Matthew Hodgkins

  Hi All, I am trying to uninstall Exchange 2007 on a secodary server which has been decommissioned for quite a while (cleaning up after an old Network Admin). The only roll the server had was "Mailbox Role" (the primary server also has this). I have tried uninstalling using Programs and Features GUI tool but that hung on Mailbox Role Checks. I then tried uninstalling Exchange by running Setup.com /mode:uninstall. It has been stuck on 1% of "Mailbox Role Checks" for over 3 hours now. Is there any other options I have for uninstalling Exchange 2007 so the old server can be removed from the Exchange Management console?

• Como instalar Windows (x86/x64) sobre Linux (Ubuntu)

  - by yorrany

  I installed Ubuntu edition (10.04) on my windows 7, completely eliminating it to the original installation. After I was forced to reverse the process, but could not find tools or explanations of how to do it. To clarify the equipment, it is: a netbook, acer, no optical drive cd / dvd, the process should be fully via USB. I hope I was clear enough, count on the support of you. Thank you. -- Instalei a edição Ubuntu (10.04) sobre meu Windows 7, eliminando completamente a a instalação original. Depois fui forçado à reverter o processo, mas não encontrei ferramentas ou explicações de como fazê-lo.

• Redirect users to internal webpage on first visit

  - by Sihan Zheng

  I have a lan of maybe 20 - 30 computers, and a Windows server 2003 server on hand (I can also run any x86 Linux distro). What I am trying to do, is to redirect users to a webserver inside the LAN the first time they visit certain domains. For example, the first time a user visits "google.com", they will be redirected to 192.168.1.2 (a webserver, where they will be shown a custom webpage), attempts after that will go to google. Pretty much what I am trying to do, is to provide a captive server like service, showing people a custom webpage the first time they try to access certain websites (but not others). I'm pretty flexable on how this can be done, as long as it works. Can you guys give me an idea on how to approach this problem? I am looking for (hopefully) a free solutions. Thanks

• Generating SSL certificates

  - by user73483

  Hi, I was wondering if anyone has any idea in how to generate a signed CA cert and key using openssl? I have found this website (http://dev.mysql.com/doc/refman/5.1/en/secure-create-certs.html) to generate the client and server certs for mysql server but the example is a self-signed certificate. I use the following command for running the server and client using openssl and the generated certs and keys: openssl s_server -accept 6502 -cert server-cert.pem -key server-key.pem -CAfile ca-cert.pem -www openssl s_client -connect 192.168.1.92:6502 -cert client-cert.pem -key client-key.pem -CAfile ca-cert.pem The error output I get is "Verify return code: 18 (self signed certificate)".

• Is MS Forefront Add-in for Exchange server detecting HTML/Redirector.C incorrectly?

  - by rhart

  Users of a website hosted by our organization occasionally send complaints that our registration confirmation emails are infected with HTML/Redirector.C. They are always using an MS Exchange Server with the MS Forefront for Exchange AV add-in. The thing is, I don't think the detection is legitimate. I think the issue is that the link in the email we send causes a redirect. I should point out that this is done for a legitimate purpose. :) Has anybody run into this before? Naturally, Microsoft provides absolutely no good information on this one: http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Trojan%3aHTML%2fRedirector.C&ThreatID=-2147358338 I can't find any other explanation of HTML/Redirector.C on the Internet either. If anyone knows of a real description for this virus that would be greatly appreciated as well.

• What compatibility trade-offs do we need to make in order to use a hardened SSL config for Nginx?

  - by nathan.f77

  I found some hardened SSL settings in github.com/ioerror/duraconf. Here is the header from the config: This is an example of a high security, somewhat compatible SSLv3 and TLSv1 enabled HTTPS proxy server. The server only allows modes that provide perfect forward secrecy; no other modes are offered. Anonymous cipher modes are disabled. This configuation does not include the HSTS header to ensure that users do not accidentally connect to an insecure HTTP service after their first visit. It only supports strong ciphers in PFS mode: ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; # Only strong ciphers in PFS mode ssl_ciphers ECDHE-RSA-AES256-SHA:DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA; ssl_protocols SSLv3 TLSv1; If we were to use these settings on our website, what does "somewhat compatible" mean? For example, would IE6 still be able to connect?

• why use mixed-based replication for mysql

  - by Alistair Prestidge

  I am in the process of configuring MySQL replication and am intending to use row-based-replication but I was also reading up about mixed-based replication. This is where statement-based is the default and then for certain circumstances (http://dev.mysql.com/doc/refman/5.1/en/binary-log-mixed.html) MySQL will switch to row-based. The list is quit vast on when it will switch to row-based. My questions are: Does any one use mixed? If yes why did you chose this over just using one or the other? Thanks in advance

• Handling Junk Email with Apple Mail.app and Gmail

  - by Axeva

  I've just setup my Apple Mail client to work with Google Apps through IMAP. One lingering question is how to best handle SPAM (Junk Mail), however. In their Help section, Google recommends that we disable junk filtering on the client. http://mail.google.com/support/bin/answer.py?answer=78892 This leads me to wonder what we should do when a junk message makes it past Google's filter? Do I just delete the message? If I do, the Google spam filter will never improve and "learn" that the message was junk. Do I have to log in to the web interface at Google to mark the message as spam? That seems a bit arduous for every spam email I get. What's the best way to handle this? Thanks!
