  • Mail Server using Postfix

    - by unknown (google)
    I have currently set up my web application on Amazon EC2 server. As a well known fact sending email from EC2 has a problem. As a cheap and long lasting solution instead of using "authsmtp" is it possible to rent a server and use it as a Mail Server? I am currently looking for cheap hosting which will give me root access so that it can be configured and used as a relayhost. I am curently using Postfix as MTA. Has any one implemented this before? I am curious about its feasibility of this solution. I guess common requirements are: Dedicated IP which is not black listed Open relay( open to my Server only) Any Tips for Header configurations to keep the mails out of spam folder. This is like exactly cloning authsmtp for personal use. Any suggestions for other Mail Server software instead of Postfix?

  • Door with keypad that can be controlled by website

    - by pbz
    Hi, I'm looking for some kind of the door/system that would allow us to install a door lock with a keypad. When somebody goes to that door they would enter a number that would open the door. The twist is that we need to be able to change the key combination that opens the door from a website. It needs to allow me to programmatically change the key combination required to open the door without somebody physically going there to do it. Any ideas what kind of hardware/software we would need to do this? Thanks a lot!

  • Has the hardware in my modem gone bad?

    - by Tyler Scott
    I contacted CenturyLink about my modem recently and received useless and unrelated information. The problem seems to be that the modem will no longer save settings, the web interface is unusable except in internet explorer for some reason, and the modem keeps resetting. CenturyLink claimed it had to do with signal strength but I checked and it is currently between good and outstanding according to this. All of the lights remain green even when it starts acting up and I lose internet and shortly before it crashes and reboots. Does anyone have any idea what is going on or what I can do to fix it? (Asking CenturyLink again is obviously not going to help.) Update 1: Accessing the syslog from the web interface causes a crash. After it reboots, the log looks like as follows: 01/01/1970 12:01:29 AM Ethernet Ethernet client connected ,ip(192.168.0.2), mac(1c:6f:65:4c:6d:3b) 01/01/1970 12:01:38 AM Wireless 802.11 client connected ,ip(192.168.0.18), mac(d0:df:c7:c2:73:ca) 01/01/1970 12:01:41 AM System Event Line 0: VDSL2 link up, Bearer 0, us=20128, ds=40127 01/01/1970 12:01:43 AM dhcp6s[2028] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:50 AM dhcp6s[2469] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:52 AM radvd[2306] poll error: Interrupted system call 01/01/1970 12:01:56 AM PPP Link PPP server detected. 01/01/1970 12:01:56 AM PPP Link PPP session established. 01/01/1970 12:01:56 AM PPP Link PPP LCP UP. 01/01/1970 12:01:56 AM System Event Received valid IP address from server.

  • Opening offline version of Microsoft Books Online in browser

    - by ercan
    I often use the MSDN website for language reference. In order to make navigation faster, I downloaded the offline version of SQL Server 2005 Books Online from here: http://www.microsoft.com/downloads/details.aspx?familyid=be6a2c5d-00df-4220-b133-29c1e0b6585f&displaylang=en The reason why it is 137MB is that it comes with its own GUI, which, not surprisingly, is rather poor! Apparently though, the pages are written in html. The URIs look like: ms-help://MS.SQLCC.v9/sqlcc9/html/674933a8-e423-4d44-a39b-2a997e2c2333.htm . I can open the URI in IE, but with errors. Do you know if I can open them with Firefox and how? Or is there a simple HTML version of "MS Books Online", for example in a ZIP file?

  • how to split a pcap file into a set of smaller ones

    - by facha
    Hi, everyone I have a huge pcap file (generated by tcpdump). When I try to open it in wireshark, the program just gets unresponsive. Is there a way to split a file in set of smaller ones to open them one by one? The traffic captured in a file is generated by two programs on two servers, so I can't split the file using tcpdump 'host' or 'port' filters. I've also tried linux 'split' command :-) but with no luck. Wireshark wouldn't recognize the format.

  • Workaround with paths in vista

    - by Argiropoulos Stavros
    Not really a programming question but i think quite relative. I have a .exe running in my windows XP PC. This exe needs a file in the same directory to run and has no problem finding it in XP BUT in Vista(I tried this in several machines and works in some of them) fails to run. I'm guessing there is a problem finding the path.The program is written in basic(Yes i know..) I attach the code below. Can you think of any workarounds? Thank you The exe is located in c:\tools Also the program runs in windows console(It starts but then during the execution cannot find a custom file type .TOP made by the creator of the program) ' PROGRAMM TOP11.BAS DEFDBL A-Z CLS LOCATE 1, 1 COLOR 14, 1 FOR i = 1 TO 80 PRINT "±"; NEXT i LOCATE 1, 35: PRINT "??

  • Why does Google Reader use up so much memory?

    - by Ivo
    I'm running the dev version of Chrome and just found out I could see the memory usage of every tab (press shift + ESC to find out yourself). Turns out the Shockwave Flash plugin uses 240 MB of memory and 27% of CPU while having open Google Reader. Killing this page brings it down to 50 MB. I reckon it builts up after reading through about 100 feeds. So my question is: why does it take up so much memory and what should I do to diminish it? Why I care? I often don't restart my browser (or laptop for that matter) and keep the Google Reader tab open for long periods of time. The memory does start to add up that way. Plus I have the feeling, perhaps incorrect, that it slows things down as well looking at the CPU usage. Side note: using Chrome 4 on Windows 7 (32 bit)

  • Changing file extension associations

    - by ldigas
    What is the easiest way to permanently change association (program which opens etc.) for several file extensions at once? What I mean? Let's say you used TextEditorUncool up until now to open txt, dat, bat and abc files. Now you got TextEditorReallyCool and you wish if there was an application which on the left had a name of the program, and on the right a list of file extensions associated with it (which it, let's say, opens). Is there such a thing? Usually programs change this thing during installation (some even ask before), but in the case of portable programs one usually has to do it by hand, and for editors which open a gazillion of different file extensions, it gets tiresome really fast. All ideas welcomed !

  • SOHO NETGEAR wireless router disconnects when downloading torrents

    - by Lirik
    I have a NETGEAR WGT624 wireless router at home which dies when there is a heavy torrent load. I open up my torrent client and it downloads for about 5 to 10 minutes and it continues to increase the number of seeds (goes up to 70-80 seeds), but after that the router simply fails and I have to restart it in order to get an internet connection again. When I connect directly via an ethernet cable the router and open up the torrent client, then it seems to be doing fine, but when I go wireless then the router stops working properly (although all the lights are still blinking as normal). Is there any way that I can fix this? New router firmware? Change some router options? Feed it a cookie? Anything?

  • Is there a way to prevent output from backgrounded tasks from covering the command line in a shell?

    - by Chris Pick
    I would like to be able to run task(s) in the background of a shell and not have their output to stdout or stderr cover the command line at the bottom. Frequently I need to run other commands to interact with the background processes and would like to do so from the same shell without having to open up another terminal or using multiplexer to split the terminal like screen. Ideally there would be some setting that I just don't know about (I commonly use bash or ksh), but a new or different shell or a script would be fine by me. I'm open to any suggestions and appreciate any help, thanks.

  • Pinning Google Chrome's "Application Shortcuts" to the Windows 7 Taskbar

    - by Humphrey
    I love the idea behind Google Chromes Application Shortcuts, but they don't integrate well for me into the Windows 7 taskbar. Ideally, I'd like to be able to have my most used webpages (gmail, calendar, etc) as separate windows, pinned to the Windows 7 taskbar. I've created some application shortcuts on my desktop, but I've come across the following problems. If I open my gmail application shortcut, and then later on open a normal chrome window the new window will also use the gmail icon in the taskbar, even if that window has nothing to do with gmail. (What's weirder, is that this new window then uses a high-res gmail icon, but my actually application shortcut window uses a low-res icon. If I pin the application shortcut to the taskbar, then the icon turns into the regular chrome icon. Any idea's how to fix these issues? Or are they bugs in google chrome? Chrome version: 4.0.249.89

  • Firefox's master password does not protect my web accounts

    - by Mehper C. Palavuzlar
    I've set up a master password in Firefox 3.6 but it's not working as I expected. I always save my passwords within Firefox for frequently visited sites like Facebook, Yahoo! mail, Gmail, Twitter etc. and this way I don't have to type in my password every time I open that site. When I open Firefox, it asks for the master password but when I click Cancel, it opens normally, and lets me directly in my Facebook page, or Yahoo! Mail page. Why doesn't it protect my accounts? This way, anyone using my computer can see my accounts and it's totally pointless for me to use this master password. How can I protect my accounts with saved passwords in Firefox?

  • How to install PHP, Pear, PECL, and APC with Homebrew on Mac OS X?

    - by Andrew
    I'm trying to install APC for PHP 5.3 in the easiest way possible. I love Homebrew so I started down that route. I was able to install PHP 5.3.6 with this command: brew install https://github.com/adamv/homebrew-alt/raw/master/duplicates/php.rb --with-mysql I think this is supposed to install PHP, Pear, and PECL. It seems to install these just fine. Now when I try to install APC: $ pecl install apc downloading APC-3.1.9.tgz ... Starting to download APC-3.1.9.tgz (155,540 bytes) .................................done: 155,540 bytes Warning: require_once(Archive/Tar.php): failed to open stream: No such file or directory in PackageFile.php on line 305 Warning: require_once(Archive/Tar.php): failed to open stream: No such file or directory in /usr/local/Cellar/php/5.3.6/lib/php/PEAR/PackageFile.php on line 305 Fatal error: require_once(): Failed opening required 'Archive/Tar.php' (include_path='/usr/local/Cellar/php/5.3.6/lib/php') in /usr/local/Cellar/php/5.3.6/lib/php/PEAR/PackageFile.php on line 305 How can I fix this?

  • What is the list of special variables available when writing a shell command for a context menu

    - by giovanni.pellicciotta
    When extending the Windows' shell context menu (e.g. for adding an 'Open command here' prompt on directories), a 'command' key needs to be created in the registry. The value of this 'command' key apparently can be any valid command line. I want to know which 'special variables' are available for use inside this command line. For example, I use following command for opening and cmd window from within a directory's context menu (*): cmd.exe /e:on /f:on /s /k pushd "%V" I cannot find any reference to what %V actually means or what the full list of such variables is. (*) Following registry keys are created for this: [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell] @=Open Command Prompt Here" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell\command] @="cmd.exe /e:on /f:on /s /k pushd \"%V\""

  • Why does TeamViewer launch a web server?

    - by OverTheRainbow
    Hello I just read this article which I find concerning: "After 90 minutes of troubleshooting, Nash traced the problem to TeamViewer, which he used to remotely administer the client's servers. It turns out the program had opened up its own webserver on the client's machine as soon as Apache went down and in the process made it impossible for the client, a large provider of business software, to restart its proper website." http://www.theregister.co.uk/2009/07/24/teamviewer_snafu/ I started using TeamViewer recently because it's just much better than UltraVNC (runs on both XP and Vista, the server dials out instead of requiring the user to open a port on their router + better performance than UVNC)... but I thought that TeamViewer had both the server and client connect out to TV's web server for data to flow between the two hosts. Why does TV even need to open a web server on the server host? Thank you.

  • Mac OS X Lion 10.7.2 update breaks SSL

    - by mcandre
    Summary After updating from 10.7.1 to 10.7.2, neither Safari nor Google Chrome can load GMail. Spinning Beachballs all around. The problem isn't GMail; Firefox loads GMail just fine. The problem isn't limited to Safari or Google Chrome; Other applications also have trouble with SSL: Gilgamesh and Safari. Any program that uses WebKit (Google Chrome, Safari) or a Cocoa library (Gilgamesh) to access the Internet has trouble loading secure sites. The various forums online suggest a handful of fixes, none of which work. Analysis Fix #1: Open Keychain Access.app and delete the Unknown certificate. The 10.7.2 update also prevents Keychain Access from loading. The Keychain program itself Spinning Beachballs. Fix #2: Delete ~/Library/Keychains/login.keychain and /Library/Keychains/System.keychain. This temporarily resolves the issue, and lets you load secure sites, but a minute or two after rebooting or hibernating somehow magically undoes the fix, so you have to delete these files over and over. Fix #3: Delete ~/Library/Application\ Support/Mob* and /Library/Application\ Support/Mob*. There is a rumor that the new MobileMe/iCloud service ubd is causing the issue. This fix does not resolve the issue. Fix #4: Open Keychain Access, open the Preferences, and disable OCSP and CRL. This fix does not resolve the issue. Fix #5: Use the 10.7.0 - 10.7.2 combo installer, rather than the 10.7.1 - 10.7.2 installer. When I run the combo installer, it stays forever at the "Validating Packages..." screen. The combo installer itself is bugged to He||. I force-quit the installer, ran "sudo killall installd" to force-quit the background installer process, and reran the combo installer. Same problem: it stalls at "Validing Packages..." Recap The only fix that works is deleting the keychains, but you have to do this every time you reboot or wake from hibernate. There is some evidence that ubd continually corrupts the keychain files, but the suggested ubd fix of deleting ~/Library/Application\ Support/Mob* and /Library/Application\ Support/Mob* does not resolve this issue. Evidently, something is corrupting the keychain over and over and over. Also posted on the Apple Support Communities.

  • Is there a way to browse a media server (MediaTomb) with a media player (VLC)?

    - by twig
    I currently have an EEE PC set up with LinuxMint as my media server using MediaTomb. I use VLC as my media player on another Windows computer to watch videos off the media server. It works fine, but the current process is: Open up browser and navigate to folder Find the file I want to play and copy URL Paste URL into VLC and watch. This is fine for me on the PC, but it is a little troublesome for my parents to grasp (or for me to use on the phone). Ideally I'd like to: Open up VLC Browse to the file (using VLC) Click/select to play If there is any solution which is similar to this, please let me know. I'm willing to change the software on both server and client to accommodate (although it somewhat depends on which formats are supported on the server) Side note: I've tried searching online for this but I find a lot of jargon such as "media server/centre", media streaming, DLNA, UPNP and feel that some people are either using them interchangeably or incorrectly.

  • How do most small businesses acquire Office licenses?

    - by LuckyLindy
    A company I sometimes consult for is relatively small (40 employees), and they have a royal mess of Office licenses. OEM, Retail, Upgrades, O2K/XP/2K3/2K7, etc. They basically buy whatever retail license they can find cheapest online, and have someone track it all in a spreadsheet for compliance purposes. They also use a Microsoft Action pack license for getting another 10 copies of Office/Vista for free. While it all seems to follow Microsoft's licensing rules, it also seems horribly inefficient. I've talked to them about Microsoft's Open license, but they don't see any advantage to it. What do other relatively small businesses do? Are Open licenses popular, or do most of them just buy retail like my client?

  • Please help, I am losing my data?

    - by 5YrsLaterDBA
    I was trying to remove MSDN Library-January 2002 by using Revo Uninstaller. I allowed it to delelet those leftover registry entries(my fault, i should be more careful and don't do that). Now my machine is almost unaccessible, cannot open that Revo Uninstaller to recovery, cannot open Windows Explorer, cannot run CMD command from run, all executable shortcuts are not work anymore. I guess I have to reinstall everything but how can I get my data out of the machine? It is a Dell laptop with Windows XP. I am afraid if I restart my machine, my machine will not come back anymore. Please help.

  • Word 97 installed with Outlook XP - Cannot use Word for default editor from Windows Explorer.

    - by xpda
    I am using Outlook 2002 (Office XP Update) with Word 97 and Excel 97. (The reason is that Microsoft refused to activate my legit copy of office 2003 when I got a new motherboard, Word XP crashed too much, and I prefer the newer Outlook. I would rather not send Microsoft more money to upgrade since they refuse to activate what I've already purchased. Please don't recommend an upgrade.) Now, I can tell Windows Explorer to use Word 97 to open, for example, a .txt file. But whenever I try to open the text file from Explorer, it either (a) started the Windows XP installer, or (b) tells me that the .txt file is an invalid Win32 application. Is there some way to straighten out the registry without reinstalling Windows XP? Excel 97 and Outlook 2002 are working fine.
