Microsoft Security Essentials howto auto download definition updates

- by chris.nullptr

I use Microsoft Security Essentials as my antivirus on my Win7 box. New virus definitions to Security Essentials are installed using Windows Update. However, the updates are marked as optional by default, as opposed to important which means that they don't get installed automatically. I have to select the updates from the list of optional updates and install them manually. Is there a way to change this behavior so that new definitions are marked as important and installed automatically?

What steps can you take to ensure sane build environments when compiling software?

- by Chris Adams

Hi guys, I've been stuck with a compilation problem when building a standardised virtual machine on CentOS 5.4, and I'm in the dark here as to a) why this error is occurring, and b) how to fix it, and in the hope that someone else stumbles across this problem too, I'm hoping someone can help me find the solution here. I'm getting a configure: error: newly created file is older than distributed files! error when trying to compile Ruby Enterprise like below when I try to run the installer, and the solutions offered to on the forums (of checking the tine, and touching the files to update the time associated with them) don't seem to be helping here. What steps can I take to work out what the cause of this problem? [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ sudo ./installer Welcome to the Ruby Enterprise Edition installer This installer will help you install Ruby Enterprise Edition 1.8.7-2009.10. Don't worry, none of your system files will be touched if you don't want them to, so there is no risk that things will screw up. You can expect this from the installation process: 1. Ruby Enterprise Edition will be compiled and optimized for speed for this system. 2. Ruby on Rails will be installed for Ruby Enterprise Edition. 3. You will learn how to tell Phusion Passenger to use Ruby Enterprise Edition instead of regular Ruby. Press Enter to continue, or Ctrl-C to abort.

I've also tried running this after updating time with an ntp-client, so no avail. I tried this after reading this post here of someone having a similar problem [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ date Tue Apr 27 08:09:05 BST 2010 The other approach I've tried is to touch the top level the files in the build folder like suggested here, but this hasn't worked either (an to be honest, I'm not sure why it would have worked either) [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ sudo touch ruby-enterprise-1.8.7-2009.10/* I'm not sure what I can do next here - the problem seems to be the bash configure script that returns this error error: newly created file is older than distributed files!, at line :2214 { echo "$as_me:$LINENO: checking whether build environment is sane" >&5 echo $ECHO_N "checking whether build environment is sane... $ECHO_C" >&6; } # Just in case sleep 1 echo timestamp > conftest.file # Do `set' in a subshell so we don't clobber the current shell's # arguments.

There's nothing I see in the crontab that suggests any hourly tasks are run that might change the state of the system enough make a difference to this script working. I'm totally at a loss when it comes to debugging beyond here. What's the best approach to take here? Thanks

Quickest way to run IISRESET as administrator

- by Chris Adams

Trying to optimize my day here, making do with IIS... When executing IISRESET from the Run dialog or from cmd.exe, I get an access denied error. So executing IISRESET gets annoying - involving both mouse and keyboard: Start - Run - cmd (right-click, Run as Administrator) Agree to the UAC dialog Type iisreset, hit enter I'm looking to be able to run IISRESET as quickly as possible. Ideally I could just go Start - Run - iisreset - Enter, and the UAC prompt would pop up. I tried to enable "Run this program as an Administrator" but it was greyed out, even when I opened the properties dialog as NT AUTHORITY\SYSTEM. Thinking of making a Visual Studio macro and a toolbar button; anyone got any other ideas?

If spaces in filenames are possible, why do some of us still avoid using them?

- by Chris W. Rea

Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. NamingThingsLikeThis.txt -- despite most modern operating systems supporting spaces in filenames. Non-technical people must look at filenames created by geeks and wonder where we learned English. So, what are the reasons that spaces in filenames are avoided or discouraged? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant reasons, other than the practice being a vestigial preference? UPDATE: Thanks for all your answers! I'm surprised how popular this was. So, here's a summary: Six Reasons Why Geeks Prefer Filenames Without Spaces In Them It's irritating to put quotes around them when referenced on the command line (or elsewhere.) Some older operating systems didn't used to support them and us old dogs are used to that. Some tools still don't support spaces in filenames at all or very well. (But they should.) It's irritating to escape spaces when used where spaces must be escaped, such as URLs. Certain unenlightened services (e.g. file hosting, webmail) remove or replace spaces anyway! Names without spaces can be shorter, which is sometimes desirable as paths are limited.

Convert HTACCESS mod_rewrite directives to nginx format?

- by Chris

I'm brand new to nginx and I am trying to convert the app I wrote over from Apache as I need the ability to serve a lot of clients at once without a lot of overhead! I'm getting the hang of setting up nginx and FastCGI PHP but I can't wrap my head around nginx's rewrite format just yet. I know you have to write some simple script that goes in the server {} block in the nginx config but I'm not yet familiar with the syntax. Could anyone with experience with both Apache and nginx help me convert this to nginx format?

Firefox saving password for a 3-field password form in Firefox

- by Chris

I've been requested to find a method of saving passwords on a form that uses three inputs, all set as type="password". It seems that Firefox will only save the password for the first password input. Here's the code foundation, which I simplified. <FORM NAME = "PSWRD" ACTION="index.pgm" Method="POST" TARGET="frame"> <INPUT TYPE="PASSWORD" NAME="PASSWORD1" SIZE="5" MAXLENGTH="5"> <INPUT TYPE="PASSWORD" NAME="PASSWORD2" SIZE="10" MAXLENGTH="10"> <INPUT TYPE="PASSWORD" NAME="PASSWORD3" SIZE="10" MAXLENGTH="10"> <INPUT TYPE="submit" VALUE="ENTER"> </form>

Redirecting a port to a remote server on windows

- by Chris T

I only have command line access to a server and I'm not allowed to disable the antivirus (which blocks netcat). What I would like to do is have a program that listens on port A and when a remote computer connects to it redirect all input/output of that socket to another server on a different port. Basically a small proxy. Is there anything that will let me do this from command line? If not I could try coding something simple that does this with C++

Fighting Spam - What can I do as an: Email Administrator, Domain Owner, or User?

- by Chris S

This is a Canonical Question about Fighting Spam. Also related: How to stop people from using my domain to send spam? There are so many techniques and so much to know about fighting SPAM. What widely used techniques and technologies are available to Administrator, Domain Owners, and End Users to help keep the junk out of our inboxes? We're looking for an answer that covers different tech from various angles. The accepted answer should include a variety of technologies (eg SPF/SenderID, DomainKeys/DKIM, Graylisting, DNS RBLs, Reputation Services, Filtering Software [SpamAssassin, etc]); best practices (eg mail on Port 25 should never be allowed to relay, Port 587 should be used; etc), terminology (eg, Open Relay, Backscatter, MSA/MTA/MUA, Spam/Ham), and possibly other techniques.

SQL Server Express backup/restore error: The Media Family on Device is Incorrectly Formed.

- by Chris

Basically, I'm having this issue: http://www.sqlcoffee.com/Troubleshooting047.htm What I'm doing is running a script I found online (http://pastebin.com/3n0ZfybL) to do a full backup, then rar'ing up the file and moving it to my computer. The CRC of the backup file inside the rar is correct on both computers, so there is no problem with data being corrupted when I transfer it. But then I go and try to restore the database on my dev computer here and I get the errors "sql server cannot process this media family" ... "msg 3013". Why is this happening? I'd test out the backup on the server I'm getting it from, but it's a production server. Edit: I was about to say how I wasn't doing anything stupid like trying to restore the database to an earlier version of SQL Server, but apparently I am: From: Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (Intel X86) Mar 29 2009 10:27:29 Copyright (c) 1988-2008 Microsoft Corporation Express Edition on Windows NT 6.0 (Build 6002: Service Pack 2) To: Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 6.0 (Build 6001: Service Pack 1) Let me get back to this post after I reinstall this.

Using perl 5.8.8 on linux, need the output of a perl 'system' command to be hidden. The command in my code is : system("wget", "$url", "-Omy_folder/$date-$target.html", "--user-agent=$useragent"); I've tried using " /dev/null 2&1" in different places in the system command, like this- system("wget", "$url", "-Omy_folder/$date-$target.html", "--user-agent=$useragent"," /dev/null 2&1"); Can anyone help me with where the redirection to /dev/null should be?

Change the Default Date setting in Word 2010

- by Chris

I am using Word 2010 and Windows 7. You know how when you start typing a date in Word it will automatically suggest what it thinks you want? Like if I start typing “6/29”, a little grey bubble will display “6/29/13 (Press ENTER to Insert)”. How do I get it so the bubble will display the year in a 4 digit format, such as "6/29/2013 (Press Enter to Insert)"? The below picture is how it looks when typing a date into Word. I have already gone to the Date & Time option under the Insert menu and the date format that I want is already selected. I think this is only for using quickparts anyway, so the date automatically updates when you open a document. The Region and Language settings under the Control Panel are correct as well. I thought at one point I found it somewhere under options, but I am sure I looked through everything many times and I can’t find it. I posted this exact question at the Microsoft website and someone replied: Go to the Windows Control Panel and click on Clock, Language and Region and then on Change the date, time, or number format and then modify the Short date format so that it is what you want to be used. So please don't suggest this again, because in my question I did say that I already tried this and it doesn't work, at least not for Word, in this situation. Thanks.

SQLVDI error - attempt to release mutex not owned by caller

- by Chris W

I've started getting some errors in the App event log of one of our database servers (Windows 2003 & SQL Server 2005). The nightly full database backups are completing successfully however immediately after the job success is written to the event log there is a run of entries that say: SQLVDI: Loc=CVDS. Desc=Release(ClientAliveMutex). ErrorCode=(288)Attempt to release mutex not owned by caller. There's five of these logged - the server itself has more than 20 databases on it which are all backed up successfully. The server is backed up by Bacula using a VSS backup. Has anyone got any ideas what would be causing the errors? They seem to have started after a re-boot on Friday to install some patches which included KB960089. Edit: After getting the errors for a few days they've now stopped without any action on my part other than letting the backups continue as they were. It may be a coincidence but they stopped after Bacula completed its weekly full rather than the daily incremental backup.

Network Traffic Log

- by Chris Becke

Background - On my "home" network I have a Linksys WTR45GL router providing my internet access as well as a wireless AP. Connected I have * 2 Windows PCs (wired) * At least one laptop (Wired) * Some 802.11 enabled handheld consoles (PSPs) * A Nintendo Wii * Some windows XP pcs used by the people in the granny flat. Where I live, South Africa, well, 1Gb worth of monthly cap is, while not expensive, costly enough that I'd like to be sure that all the bandwidth used by devices on my network is ... well ... legitimate and not the result of neighbors parasiting my wireless, malware or just the result of "liberal" download policies in my software. I got the Linksys WRT45GL on the understanding that there were custom firmwares (DD-WRT and Tomato) that allowed bandwidth tracking, but there doesn't seem to be any facility to get a log of traffic that can be examined to see (a) which local devices were the biggest consumers of bandwidth and (b) what they were connected to. What tools are there for logging traffic such that, when it gets to that OMG moment in the month when all my bandwidth is gone, I have a chance to find out what the hell used it all up (and hopefully attempt some corrective action).

"Unsupported compression method 98" error when unzipping a file. What tools support it, other than W

- by Chris W. Rea

I'm getting an error message: "unsupported compression method 98" when unzipping a file somebody sent to me. I've tried both an older version of WinZip, and 7-Zip 4.65. I've already asked the person to avoid using a non-standard compression method and re-send the file. I know WinZip (of which they are using a newer version) has compatibility options. But, I'm wondering: What archiving utilities, other than WinZip, support this "compression method 98"? In particular, is there a free and/or open source tool that supports that method? If not, why not? Is the method strictly proprietary to WinZip?

Here are the commands I am using: chown -R apache uploads chmod -R 770 uploads Source: http://www.mysql-apache-php.com/fileupload-security.htm Instead it seems that although it is keeping visitors from seeing the files, it is not allowing apache to serve them. Do you have any ideas?

What would keep a Microsoft Word AutoNew() macro from running?

- by Chris Nelson

I'm using Microsoft Office 2003 and creating a bunch of template documents to standardize some tasks. I know it's standard practice to put the templates in an certain place Office expects to find them but that won't work for me. What I want is to have "My Template Foo.dot" and "My Template Bar.dot", etc. in the "My Foo Bar Stuff" on a shared drive and users will double click on the template to create a new Foo or Bar. What's I'd really like is for the user to double click on the Foo template and be prompted for a couple of items related to their task (e.g., a project number) and have a script in the template change the name that Save will default to something like "Foo for Project 1234.doc". I asked on Google Groups and got an answer that worked....for a while. Then my AutoNew macro stopped kicking in when I created a new document by double clicking on the template. I have no idea why or how to debug it. I'm a software engineering with 25+ years of experience but a complete Office automation noob. Specific solutions and pointers to "this is how to automate Word" FAQs are welcome. Thanks.

os x 10.4 server enable mail for account via terminal

- by Chris

Hello- I have an account on an OS X 10.4 server that I don't have physical access to (must use SSH). For arguments sake, let's call the account 'Bob'. Bob's account exists and appears to be fully functional, however he does not have email. How do I enable, via terminal, email for Bob's account, such that he can receive email at [email protected]? I already have the mail server all set up with several working accounts in it, I just need to add Bob. I have searched all over Google for over six hours now, but can't seem to find an answer that fits my situation. Any help is appreciated. P.S. - I am not adverse to just deleting the account and starting over, if that would make things easier...

Does water damage a fiber optic / cat5 cable

- by chris

One of the buildings I support recently had an adventure with a broken fire sprinkler. Lots of water everywhere. One of the "drains" the water used was the vertical risers between network closets. The cable plant in this building has bundles of cat5e as well as conduit with bundles of multimode fiber optic cables. The fiber is standard multi strand plenum rated stuff that terminates in boxes that have the patches to the switches. As far as I can tell, no water got near the ends of the cables (fiber or copper) but the conduit was saturated, and is likely still saturated because there isn't any air flow to dry the cables out. My gut reaction is that while it didn't do the cables any favors, it likely also isn't going to cause any problems. A little more reading / googling around leads me to believe that the water may cause problems down the road. Some pretty pictures so everyone knows what I'm talking about: Fiber conduit: Vertical riser, going down: Vertical riser, going up: Does anyone have any experience with this sort of damage and how to deal with it? Should we just ask the insurance adjuster to add "pull new structured cable" to the list of things to be replaced? And, if the opinion is "replace it because it'll start failing randomly over time" please include links that describe the specific failure modes, so I've got some ammo to use with the adjuster.

How to jump through an IP ad in firefox?

- by chris

I use firefox with a lot of anti-ad extension, like adblock, NoScript, Ghosty etc. I found this IP 220.191.158.69 always in the list of NoScript, I want to ban this IP. I have checked it, searched it. It is from China telecom damn Ad. I guess NoScript can ban this IP already, but When I do not allow that IP, sometimes a webpage can not be loaded at first time, I need to refresh two or more times. I hate it... So I hope there are some way or browser extensions or script can jump through this damn IP.
