• Which server software and configuration to retrieve from multiple POP servers, routing by address to correct user

  - by rolinger

  I am setting up a small email server on a Debian machine, which needs to pick up mail from a variety of POP servers and figure out who to send it to from the address, but I'm not clear what software will do what I need, although it seems like a very simple question! For example, I have 2 users, Alice and Bob. Any email to [email protected] ([email protected] etc) should go to Alice, all other mail to domain.example.com should go to Bob. Any email to [email protected] should go to Bob, and [email protected] should go to Alice Anything to *@bobs.place.com should go to Bob And so on... The idea is to pull together a load of mail addresses that have built up over the years and present them all as a single mailbox for Bob and another one for Alice. I'm expecting something like Postfix + Dovecot + Amavis + Spamassassin + Squirrelmail to fit the bill, but I'm not sure where the above comes in, can Postfix deal with it as a set of defined regular expressions, or is it a job for Amavis, or something else entirely? Do I need fetchmail in this mix, or is its role now included in one of the other components above. I think of it as content-filtering, but everything I read about content-filtering is focussed on detecting spam rather than routing email.

• How does "Compatability Mode" in Windows 7 affect the application?

  - by Robert C. Cartaino

  Background: Based on the answer given to this question: "Skype behaviour in the Windows 7 Superbar" ...you can get Skype to minimize to the system tray (rather than the task bar) by running it in compatibility mode. (red flags going off in my head) That's the behavior that I want but what does "compatibility mode" do to the executing application? I am concerned about changing the execution mode of an entire (important) application to a previous generation just to alter the user interface behavior a bit. So, what does compatibility mode actually do internally? What are the disadvantages, as in "how could the application (Skype) suffer?"

• Time Capsule Refuses to Connect After Interrupted File Transfer

  - by Steve Stifler

  I have a first generation Apple Time Capsule set up as a NAS on my network. I use the built-in hard drive for Time Machine backups, with a 1.5 TB external HDD attached to the Time Capsule over USB. Whenever I cancel a file transfer from the external drive to my Macbook (or quit a video I had been streaming from it, as was the most recent incident), I can no longer connect to the Time Capsule or the attached drive, and I have to unplug it to get it working again. How can I fix this? Is it a network error? Could the Time Capsule be at fault or could it be my computer?

• Hyperthreading vs. SQL Server & PostgreSQL

  - by IanC

  I have read that hyperthreading is a "performance killer" when it comes to DBs. However, what I read didn't state which CPUs. Further, it mostly indicated that I/O was "cut to < 10% performance". That logically doesn't make sense since I/O is primarily a function of controllers and disks, not CPUs. But then no one ever said bugs made sense. What I read also stated that SQL Server could put two parallel query ops onto 1 logical core (2 threads), thereby degrading performance. I have a hard time believing SQL Server's architects would have made such an obvious miscalculation. Does anyone have and data on how hyperthreading on current generation CPUs affects either of the RDBMSs I mentioned?

• Why is Safari on my computer rendering all of the colors -- not just for images -- incorrectly?

  - by richardhenry

  I’m not just talking about image color profile issues; every single color that the browser renders is incorrect. It’s like it’s in it’s own color space (or something!). Screenshot: http://drp.ly/DJk1O (Opera, Safari, Chrome, Firefox) Spot the odd one out? Open this up in Photoshop or similar and try using the eyedropper to select the colour. Safari renders the same hex color completely differently. That color is set using a background-color declaration in CSS, so it should be identical in all four of those browsers. Here’s the HTML I was using: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>untitled</title> <style type="text/css"> body { background-color: #114742; } </style> </head> <body> </body> </html> Literally every website I’m viewing with my install of Safari is displaying colors incorrectly. The blue of the bar on Facebook is slightly less rich. This doesn’t occur on any other Macs I’ve tried. Any idea what’s happened to my Safari install?

• Spammer relaying via Postfix mail server

  - by Paddington

  I have a Plesk 9.5 mail server (cm.snowbarre.co.za) on Ubuntu 8.04 LTS which forwards all SMTP traffic to an anti-spam server cacti.snowbarre.co.za. Many times I see the headers on the anti-spam server to contain from addresses not hosted on the mail server and I have checked and confirmed that my server is not an open relay server. How can a spammer be using my server to relay spam traffic? How can I stop this? Open relay test: paddington@paddington-MS-7387:~$ telnet cm 25 Trying 196.201.x.x... Connected to cm.

• How do I force a server to leave a SharePoint farm

  - by Stefan

  I have two web servers in a SharePoint (WSS 3.0) farm with one database server for the config and content databases. I already moved my content databases to a new database server successfully. But when I tried to move the sharepoint config database using the "stsadm deleteconfigdb" and "stsadm setconfigdb" commands, one of my servers got stuck in an intermediate state. I was able to join one of the web servers with the config database on the new server, but the other server is not able to join because it believes it is already part of the farm (which it used to be, before the move). On the central administration it says the status of the services on the server is "stopping". Even after rebooting all servers involved, uninstalling SharePoint and what not, this status does not change, and because of it, I am not able to join the second server with the new config database. I get random error messages when trying to join the farm. I believe that if I can unstuck this server, it will be able to join the farm again. The farm believes the second server is already part of it, but the web server itself knows its not. Any ideas on how to forcefully kick out a server from the farm?

• How do I make rsync also check ctime?

  - by Benoît

  rsync detects files modification by comparing size and mtime. However, if for any reason, the mtime is unchanged, rsync won't detect the change, although it's possible to spot it by looking at the ctime. Of course, I can tell rsync do compare the whole files' contents, but that's very very expensive. Is there a way to make rsync smarter, for example by checking mtime+size are the same AND that ctime isn't newer than mtime (on both source and destination) ? Or should I open a feature request ? Here's an example: Create 2 files, same content and atime/mtime benoit@debian:~$ mkdir d1 && cd d1 benoit@debian:~/d1$ echo Hello > a benoit@debian:~/d1$ cp -a a b Rsync them to another (non-exisiting) directory: benoit@debian:~/d1$ cd .. benoit@debian:~$ rsync -av d1/ d2 sending incremental file list created directory d2 ./ a b sent 164 bytes received 53 bytes 434.00 bytes/sec total size is 12 speedup is 0.06 OK, everything is synced benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:Hello d2/a:Hello d2/b:Hello Update file 'b', same size and then reset its atime/mtime benoit@debian:~$ echo World > d1/b benoit@debian:~$ touch -r d1/a d1/b Attempt to rsync again: benoit@debian:~$ rsync -av d1/ d2 sending incremental file list sent 63 bytes received 12 bytes 150.00 bytes/sec total size is 12 speedup is 0.16 Nope, rsync missed the change. benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:World d2/a:Hello d2/b:Hello Tell rsync the compare the file content benoit@debian:~$ rsync -acv d1/ d2 sending incremental file list b sent 144 bytes received 31 bytes 350.00 bytes/sec total size is 12 speedup is 0.07 Gives the correct result: benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:World d2/a:Hello d2/b:World

• IIS 7 + Tomcat 7 - how to reach http://localhost:8080/my_app under e.g. http://my_app.local

  - by Sk8erPeter

  In brief: IIS 7 + Apache Tomcat 7 + isapi_redirect.dll: I have a deployed and working Tomcat-application available under http://localhost:8080/my_app. I would like to see the same content under http://my_app.local (and NOT the default Tomcat-site [which you can see below]). How can I do that? Longer explained: I have IIS 7 (7.5.7600.16385) and Apache Tomcat/7.0.22 installed. I deployed an application (let's call it "my_app") in Tomcat, which now can be reached at http://localhost:8080/my_app, works fine. I added a new web site in IIS panel with the path of the Tomcat deployed my_app, which looks like this: "c:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\my_app" I binded the host name my_app.local. After that, I configured isapi_redirect.dll like this (or that). Now, when I open http://my_app.local, I can see the default Tomcat site (see below). BUT under http://my_app.local I would like to see the same content as under http://localhost:8080/my_app. How can I do that? Thank you very much in advance!! my config files: isapi_redirect.properties (I made a dir junction to c:\tomcat, so this also works :) ) workers.properties uriworkermap.properties rewrites.properties (empty)

• Connecting a network printer via a Thecus N2100 - works in Vista, not in Windows 7

  - by Jon Skeet

  I have a Lexmark E250d printer attached to a Thecus N2100 NAS. On Windows Vista I've managed to configure this using an "Internet" printer port with the URL of http://thecus:631/printers/usb-printer. I can add a printer in a similar way in Windows 7, but it never manages to print the test page. If I go to "Configure Port" in Vista, it just has "Security Options" - on Windows 7 it's asking about Raw mode vs LPR mode etc. On Vista I'm using an E250d-specific driver from Lexmark; on Windows 7 there's a Microsoft E250d driver, or a Universal PCL XL driver from Lexmark... I wouldn't expect this different to be related to the problem, but I thought I'd mention it anyway. (Lexmark doesn't have a Windows 7 E250d-specific driver as far as I can see.) Any suggestions? I was thinking of upgrading my main laptop from Vista to Windows 7, but I'd really like to get this sorted first... EDIT: If I connect to http://thecus:631/printers/usb-printer via Chrome while capturing with Wireshark, I get this response: HTTP/1.1 200 OK Date: Wed, 06 Jan 2010 16:47:23 GMT Connection: Keep-Alive Keep-Alive: timeout=60 Content-Language: C Transfer-Encoding: chunked Content-Type: text/html;charset=iso-8859-1 0 No idea what that's meant to be doing... EDIT: On further consultation, this would appear to be the Internet Printing Protocol which is layered on HTTP. Printing a test page successfully from Vista posts to that URL. Will attempt the same on Windows 7...

• Email encoding on IIS7

  - by Ivanhoe123

  All emails sent from the server are displaying Cyrillic letters as weird characters, for example: Можно. Regular alphabet letters are properly rendered. I searched all across the web but was not able to find any solutions. Here is some information about the system: Dedicated server with Windows 2008 and IIS7 Application are in PHP (run as FastCGI) If of any importance, Smartermail is installed on the server The emails are sent using PHPs mail() function through a Drupal website. Encoding on that site is set up properly and there are no display issues on front end. Where is the problem? How can I make Cyrillic letters to be properly encoded? Any help is greatly appreciated.

• Excel 2007 - "The macro may not be available in this workbook" Error

  - by Psycho Bob

  We use an Excel sheet that has been protected to prevent modification of it from end users. All in all they are only able to edit certain tabs to add information that will then be used to generate information on other tabs using equations and such. On the tab with the equations, a button is present called "Prep for Internal Hard Copy Print." This button runs a macro that selects the information on the tab, unprotects it, then sends a print job to the user's default printer that contains the unprotected content. Normally this works like a champ. This time around, however, the macro is throwing the following error: Cannot run the macro "FILENAME.xlsx'!MacroName'. The macro may not be available in this workbook or all macros may be disabled. As far as I can tell, the macros are still present within the workbook. This sheet is normally a .xlsm though the user saved it with a different filename as a .xlsx. Also, the macros appear only as MacroName in the .xlsm file and not "FILENAME.xlsx'!MacroName' as it does in the .xlsx. Finally, when I open the .xlsm it asks if I want to enable the macro content while the .xlsx does not prompt for this. Can anyone tell me what's going on with this sheet or know of a way that I can get the macros working in the .xlsx without having to start over with a different sheet?

• unreadable corrupted ntfs partition - lost clusters reported

  - by Eduardo Martinez

  Hi, partition magic is reporting multiple 'bad file record signature' and 'lost clusters' errors on my 250GB samsung sata disk (connected via usb on a xp sp3). Unfortunately PM is unable to fix. PM shows the drive as being NTFS, detects used space ok and also drive name. But PM browser (right click on partition, browse...) won't show anything (as if disk was empty) Windows Explorer is not even picking the drive name and reports 'the file or directory is corrupted and unreadable' PTDD partition table doctor demo tells me the boot sector is fine, and I can see all disk content on its browser - but crucially cannot copy that content over to a new disk (PTDD browser is pretty arid to say the least) Also tried - photorec-6.11.3 - it actually started to extract files but wouldn't keep file names or any folder structure (maybe I missed sth on the configuration options) - find and mount - intellectual scan went well, the only partition on the disk was detected, then tried to mount into p: but got this error on windows explorer: 'p:\ is not accesible. The media is write protected'. Find and mount allows you to create an image from partition but I don't have a disk big enough at hand. Does anyone know if this will keep the extracted files/folders structure intact? I'm starting to think the disk is pretty screwed and my chances to recover this data are slim. Please someone enlighten me with that marvellous piece of software I am missing :-) Thanks in advance

• Replication keeps popping up on SharePoint databases

  - by Ddono25

  My typical discovery scenario: We receive an alert that the transaction log is growing quickly. We are in Simple Recovery so I go to check it out. Log is already sized to 100GB and is at 80% capacity. I run the "Whats using my log files" script from SQL Server Central and see that Replication is enabled on the database. We do not set up replication, and I don't think Replication can be done on SharePoint content db's as Replication is not supported (requires PK on all tables). This has been occurring on random servers (about 5 so far, all within the past three weeks) and it only occurs on Content Databases. sp_removedbreplication does not always work in removing the Replication either. We have found that we need to run the sp_removedbreplication, change all db owners to SA and reset Recovery Mode to Simple to completely eradicate any vestiges of this bug. How would Replication be enabling itself? We have never set up Replication on these servers. There is no evidence of any type of Replication other than the 'log_reuse_wait_desc' from the DMV query and log growth. Any help on this ghost would be appreciated!

• CCD vs. CMOS webcams

  - by rob

  Several years ago, I tried a CMOS-based webcam and it really sucked. It needed an extremely brightly-lit room to work. Around the same time, I also tried a CCD camera and it worked great. But since then, I've heard that CMOS technology has advanced considerably. Is it still the case that CCD webcams will give you a better picture, or can CMOS webcams also produce a picture of similar quality at moderate to low light levels? What type of camera is used in modern integrated webcams and cameras? If CMOS cameras actually are competitive these days, how do you tell if a webcam has a newer-generation CMOS sensor instead of one of the older sensors?

• ddclient to update namecheap subdomain?

  - by LF4

  I have a subdomain that I want to update with ddclient. I configured the ddclient to get the IP from dyndns but it's not updating the subdomain on namecheap. They said to use yourdomain.com as the login instead of my actual domain. Has anyone been able to get namecheap DNS updated with ddclient? I'm running CentOS 6.2 with ddclient 3.7.3. When I run ddclient I get the following.

• How to configure IIS for SVG and web testing with Visual Studio?

  - by macias

  Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.

• Adding a GET parameter to URL causes 404 error

  - by Adrian Grigore

  I'm trying to install the syntaxhighlightter evolved plugin to my wordpress blog. I've uploaded and activated the plugin, but it did not work. I've looked into the page source code and found out that the plugin style is loaded from the following URL: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css?ver=2.0.320 This causes a 404 error (page not found). The strange thing though is that when I remove the GET parameters, the CSS loads ok: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css What could be causing this problem and how can I fix this? Unfortunately I don't know how to make wordpress drop the GET parameters when loading the stylesheet. EDIT: As I just found out, this happens only in Firefox (3.0.11). IE loads both URLs above just fine. Not that this would be of any help though, so any suggestions would be appreciated. SECOND EDIT: I tried this on my laptop and it works fine with Firefox 3.08. So this really seems to be a browser problem after all.

• Why won't IIS serve my website? - 404 Page Not Found

  - by Giffyguy

  Built a brand new server, with a fresh copy of Windows Server 2003 Enterprise x86 Edition. Installed the .NET Framework 1.1, 2.0, 3.5, and 4.0 Added the "Domain Controller" and "Application Server" roles. Created a new website, pointed it to a local directory: C:\Inetpub\angryoctopus.net\ Added the appropriate headers: angryoctopus.net, www.angryoctopus.net, TCP port 80, all IPs Moved the website content into the local directory. Configured the default document in IIS: Default.aspx Enabled ASP.NET for this website, and set it to the correct version: 2.0.50727 Configured the zone angryoctopus.net in DNS. Tested DNS lookup here to ensure DNS was functional. Opened website in VS 2008 and re-built (and debugged) to ensure the content was functional. I can clearly see that IIS is responding normally, by browsing directly to my server's IP address. Since this does not use the angryoctopus HTTP header, the default website is displayed instead: the "Under Construction" page. And yet, after all of this, angryoctopus.net still returns 404. Does anybody know what could be wrong? What troubleshooting steps have I forgotten? Is there a command-line diagnostic that might provide more information?

• Cloudfront - How to invalidate objects in a distribution that was transformed from secured to public?

  - by Gil

  The setting I have an Amazon Cloudfront distribution that was originally set as secured. Objects in this distribution required a URL signing. For example, a valid URL used to be of the following format: https://d1stsppuecoabc.cloudfront.net/images/TheImage.jpg?Expires=1413119282&Signature=NLLRTVVmzyTEzhm-ugpRymi~nM2v97vxoZV5K9sCd4d7~PhgWINoTUVBElkWehIWqLMIAq0S2HWU9ak5XIwNN9B57mwWlsuOleB~XBN1A-5kzwLr7pSM5UzGn4zn6GRiH-qb2zEoE2Fz9MnD9Zc5nMoh2XXwawMvWG7EYInK1m~X9LXfDvNaOO5iY7xY4HyIS-Q~xYHWUnt0TgcHJ8cE9xrSiwP1qX3B8lEUtMkvVbyLw__&Key-Pair-Id=APKAI7F5R77FFNFWGABC The distribution points to an S3 bucket that also used to be secured (it only allowed access through the cloudfront). What happened At some point, the URL singing expired and would return a 403. Since we no longer need to keep the same security level, I recently changed the setting of the cloudfront distribution and of the S3 bucket it is pointing to, both to be public. I then tried to invalidate objects in this distribution. Invalidation did not throw any errors, however the invalidation did not seem to succeed. Requests to the same cloudfront URL (with or without the query string) still return 403. The response header looks like: HTTP/1.1 403 Forbidden Server: CloudFront Date: Mon, 18 Aug 2014 15:16:08 GMT Content-Type: text/xml Content-Length: 110 Connection: keep-alive X-Cache: Error from cloudfront Via: 1.1 3abf650c7bf73e47515000bddf3f04a0.cloudfront.net (CloudFront) X-Amz-Cf-Id: j1CszSXz0DO-IxFvHWyqkDSdO462LwkfLY0muRDrULU7zT_W4HuZ2B== Things I tried I tried to set another cloudfront distribution that points to the same S3 as origin server. Requests to the same object in the new distribution were successful. The question Did anyone encounter the same situation where a cloudfront URL that returns 403 cannot be invalidated? Is there any reason why wouldn't the object get invalidated? Thanks for your help!

• How to check for bottlenecks in Windows Server 2008 R2

  - by Phil Koury

  I recently switched out a 10 year old server for a brand new server in a small office and upgraded from Windows Server 2000 to Windows Server 2008 R2. After the switch was complete and some configurations were changed around we are running into what appear to be some bottlenecks in the network speed. Accessing programs on the server is slower (resulting in long loading times, slower report generation, etc.) than it was on the old server hardware. I am wondering what options or tools I have, if there are any at all, to find out exactly where these hang ups might be coming from.
