• How to extend Wi-Fi signal across rooms?

  - by Sriram Krishnan

  I moved into a new place and my old Wi-Fi router just doesn't have the range to get into all the rooms. I've been investigating a lot of options and I'm wondering what other folks have done here. Moving the current location of my primary Wi-Fi router is not an option thanks to our cable provider and our landlord. Buy a bigger, beefier router (seems expensive). If so, should I go for one of those draft 802.11n ones to avoid microwave/other Wi-Fi router interference? Set up a router with DD-WRT as a repeater Leech the neighbors' open Wi-Fi access point. Alright, I was kidding about the last one but I'm genuinely curious as to what my best option is.

• How to stop basic Postfix after-queue script from BCC-ing sender?

  - by mjbraun

  I'm building a content filter for Postfix (2.9.3 package installed via apt on an Ubuntu 12.04 test VM) and I'm starting with a very basic Ruby (1.9.3) template and building up functionality. Strangely, when the script is enabled, messages sent are being forwarded on as normal, but also sent back to the sender which is not normal. Disabling the script disables this behavior. Any suggestions about what I have to change to stop that from happening? Thanks for any advice! /etc/postfix/master.cf (only the lines changed from the default) smtp inet n - - - - smtpd -o content_filter=dumper:dummy ... dumper unix - n n - 10 pipe flags=RF user=mailuser argv=/home/mailuser/mailfilter/dumper.rb ${sender} ${recipient}` /home/mailuser/mailfilter/dumper.rb #!/usr/bin/env ruby require 'open3' dir="/home/mailuser/emails" logfile="maillog.log" message = $stdin.read cmd = "/usr/sbin/sendmail -G -i #{ARGV[0]} #{ARGV[1]}" stdin, stdouterr, wait_thr = Open3.popen2e(cmd) stdin.print(message) logfile = File.open("#{dir}/#{logfile}", 'a') logfile.write(stdouterr) stdin.close stdouterr.close exit(0)

  - by dahacker89

  I am facing difficulties installing the MS SQL Server Express 2008 Service Pack 1. I already have MS SQL Server Express 2008 installed and all I want to do is to install the SP1 however I get following error message even though all features are selected, it still tells me to select one or more features: Also just for information, when I open the SQL Server Configuration Manager to manage my SQL Server Services, the following error message is displayed: If anyone who has faced this and has a solution then please let me know, as my aim is to install management studio, but for that I must have SP1 installed at least, and I'm stuck at that point. Thanks.

• Strange port forwarding problem

  - by rAyt

  I've got a strange port forwarding problem. The port forwarding to my internal webserver (10.0.0.10 on Port 80) works without a problem but the port forwarding to a windows server (10.0.0.15) on port 3389 doesn't work. The port 3389 is open. Any ideas? thanks! #!/bin/sh IPTABLES="/sbin/iptables" $IPTABLES --flush $IPTABLES --table nat --flush $IPTABLES --delete-chain $IPTABLES --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE $IPTABLES -t nat -A PREROUTING -p tcp -i eth0 -d 188.40.XXX.XXX --dport 3389 -j DNAT --to 10.0.0.15:3389 $IPTABLES -t nat -A PREROUTING -p tcp -i eth0 -d 188.40.XXX.XXX --dport 80 -j DNAT --to 10.0.0.10:80 $IPTABLES -t nat -A PREROUTING -p tcp -i eth0 -d 188.40.XXX.XXX --dport 222 -j DNAT --to 10.0.0.10:22 $IPTABLES --append FORWARD --in-interface eth1 -j ACCEPT

• Number Tabs in Chrome or Firefox

  - by Bruce Connor

  I like to use the Ctrl or Alt + Number shorcut to jump quickly to a specific tab. Problem is: When you have a lot of tabs open it is hard to look at them and quickly know which one is tab number 7. Is there a way (extension possibly) to show a tab's number in its title? This way each tab would have a number added to its title right beside the favicon. This way you could immediately tell which number you need to press to jump to a specific tab. I use both Chromium and Firefox, so I'm accepting answers for either one (though I'd prefer both =) ).

• Mouse clicks stop working sometimes

  - by AlbertoPL

  I am having a serious issue with my mouse in which it will randomly not be able to click or cause other problems. Here is the breakdown: Sometimes, I can no longer left-click on many of my windows/taskbar (in order to focus them). Even though I can still left click on my desktop icons or the currently active window, I cannot focus any of the others. Other times, when I have a browser open, I will hit to go back one page and it will automatically go forward one page. I know it's a mouse issue because this behavior stops when I unplug the mouse. Things will be fine when I plug the mouse back in, but eventually the behavior starts up again. My mouse is a Razer Diamondback 3G and I am running Windows 7 Professional 32 bit. Any ideas?

• persistant data in tor browser bundle?

  - by Snesticle

  What sort of persistent data is generated by bundled Tor? I recently did an experiment using the Tor Browser Bundle for GNU-Linux. I created two directories, A and B, and placed an identical copy of Tor in each one. Next I placed a simple python script in directory A that both launched the vidalia package and, when exiting the network, deleted the entire contents of A with the exception of itself and rebuilt the bundle from the original archive. What surprises me is that after about ten hours of browsing each, A and B now show a distinct difference in startup time. Also curious is that I get a message in the log of B that never shows up in A: new control connection open which is a notice level advisory. This has nothing to do with what I was originally testing but now I'm interested in what exactly is going on. By the way I do not have to rely on Tor for my personal safety as many are forced to do so even if you just have a hunch I'd be interested in hearing it.

• Converting mp3 to ogg, suggestive?

  - by watain

  I'm thinking about converting my mp3 based music library to ogg, due to ogg being a free and open standard format (I guess there are other reasons too). As far as I know there's a chance of losing some sound quality when converting mp3 to ogg and vice versa (?). Would you suggest converting mp3 to ogg, or is it such a bad idea that I'd have to rip all CDs to ogg instead of converting? (if this would turn up I'd rip to flac anyway I guess). How would I be able to convert mp3 to ogg the easiest way, copying ID3-Tags too? (on a *nix-based environment) Best regards!

• Apache: how to set custom 401 error page and save original behaviour

  - by petRUShka

  I have Kerberos-based authentication with Apache/2.2.3 (Linux/SUSE). When user is trying to open some url, browser ask him about domain login and password like in HTTP Basic Auth. If user cancel such request 3 times Apache returns 401 Authorization Required error page. My current virtual host config is <Directory /home/user/www/current/public/> Options -MultiViews +FollowSymLinks AllowOverride None Order allow,deny Allow from all AuthType Kerberos AuthName "Domain login" KrbAuthRealms DOMAIN.COM KrbMethodK5Passwd On Krb5KeyTab /etc/httpd/httpd.keytab require valid-user </Directory> I want to set nice custom 401 error page with some instructions for users. And I added such line in virtual host config: ErrorDocument 401 /pages/401 It works, when user can't authorize apache redirects him to my nice page. But Apache doesn't ask user login\password as it did before. I want this functionality and nice error page simultaneously! Is it possible to make it works properly?

• In Windows 7, can a program overrride file associations not set in "Set Default Programs"?

  - by KL90

  I am using Windows 7. I installed a media application (KMPlayer) that does not show up in the "Set Default Programs" list. Now in the KMPlayer's preferences, there's a setting to associate file types with itself. But when I tried that, I noticed that the files still default to Windows Media Player. So can I assume that no external application can change the program associated with a file type unless explicitly done via the: [Set Default Programs] or [Associate a file type ... with a program] or the [Open with...] options? Thanks in advance! Btw, I know there are utilities that can help me batch change it. I'm just more curious about the "rules" that Windows 7 has in place regarding file types and their associated programs.

• OpenOffice Writer page style bug?

  - by ttt

  I have a large Open Office odt document. It uses (mostly) four page styles: Left Page, Right Page, Left Chapter, and Right Chapter. The last two are custom styles that simply remove the header. But I have a problem with Chapter 4: if I try to set the style of the first page to Right Chapter, it sets the style of Chapter 3's first page! I've tried it several times, and it always does this. Am I doing something wrong, or is this a bug? Or is my file corrupted?

• vim NERDTree shortcut to an existing function

  - by Ned Batchelder

  I want to use right-arrow to open a node in NERDtree. I see there is NERDTreeAddKeyMap, but I'm too much of a vimscript newb to know how to invoke it properly. I want right-arrow to invoke activateNode. I've done it by adding this line into NERD_tree.vim itself: exec "nnoremap <silent> <buffer> <Right> :call <SID>activateNode(0)<cr>" but I want to do it the right way in my .vimrc

• Visual SVN server Running but cannot access / browse repositories

  - by user1783560

  Operating System: Windows Web Server 2008 R2 Visual SVN Version: 2.5.7 Subversion: 1.7.7 Apache: 2.2.22 I freshly installed the Visual SVN latest version on the server and created one repository in it. In the server management window, it shows that the server is up and running but when I try to browse it in a web browser, it doesn't respond.

• How to install anti-virus without administrative rights?

  - by Rohit

  In situations where the PC has no CD drive and operating a guest account with limited privileges, how to install an anti-virus tool? Malware is not permitting to open any anti-virus vendor's site and also blocking all sites opened via Google that contain the term "online scan". I somehow managed to download through mirror links with a Download Manager as the browser's download was blocked by the malware. But the problem didn't end there. After I downloaded the anti-virus tool, it failed to install because it needed administrative rights. The user didn't know the administrator password. I tried via command line with runas, but it also asks for the administrator password. The OS is Windows XP. How to deal with these type of malwares if there is a scenario that CD drive is not there only Internet is there?

• VPN Error 868 when connecting even if using IP address

  - by Fr33dan

  I am trying to connect to a public VPN from VPNGate. However when I attempt to connect to a VPN from the list using MS-SSTP protocol I get the following error: Error 868: The remote connection was not made because the name of the remote access server did not resolve. If I open a command prompt and ping the address in question it resolves to the IP shown on the listing. If I configure the VPN using that IP address directly I still receive the error even though the name no longer needs to resolve. This was working yesterday but it seems the VPN I was using has been removed from the list. What is happening and how can I fix it?

• Disable "System Memory Testing" via OMSA 6.4.0

  - by EGr

  Is it possible to disable system memory testing via OMSA 6.4.0? I can only find ways to do it using newer versions of OMSA; and I can't even see the setting in 6.4.0. I have quite a few machines that I want to disable this (BIOS) setting on, but I don't want to have to install the new OMSA and reboot. My intentions are to disable the setting so that when the systems are rebooted in the future, they don't need to go through the system memory testing. If it is possible to disable this another way, without OMSA or manually changing the BIOS settings, I would be open to that as well.

• Apache 2.0.55/PHP 5.3.5 Hangs

  - by Rushyo

  Recently inherited a Windows 2k3 server running XAMPP, including ancient copies of PHP, MySQL and Apache. I'm attempting to install a second, up-to-date PHP installation on the machine so I can reference that in future instead of XAMPP's old one. Apache starts up with this new PHP installation happily. Unfortunately, when Apache references the new PHP install, whenever I try a view a page (even a non-PHP page) it hangs. The server simply doesn't respond to any HTTP request - it doesn't crash either. It just sits there with the connection open. There are no errors/warnings/notices in either the PHP or Apache logs. I've pretty much ruled out PHP's extensions (by process of systematic elimination) and most of the INI settings. I've tried reinstalling PHP from scratch. The PHP installation is PHP 5.3.5 x86 thread-safe compiled w/ VC6. The Apache installation is Apache 2.0.55. Anyone encountered similar behaviour?

• I copied a Windows VM from Mac VMWare to Windows VMWare Player. It runs, but very slowly...

  - by thrillscience

  I copied a Windows XP VM that I've been using on my Mac (VMWare Fusion)to a Windows 7 machine that has VMWare 7 installed. I was quite pleased when it started up and appeared to work, but when I actually tried to use it, I noticed it runs very slowly. Unusably so. It takes about 10 minutes, for example, for a Visual Studio 2010 project to open (with VS 2010 running in the VM). Is this supposed to work? Is there any way to fix this VM to get it to run well under Windows VMWare Player?

• Thunderbird message pane

  - by MarkS

  I have just switched from Outlook to Thunderbird and one feature that I am missing is when I would click a folder it would open a message in the message pane automatically. Now it is always blank. I have it set to remember the last one opened so if I switch back and forth it is there. But if I just click a folder the first time that I invoke it -- the message pane is blank. Is there a setting somewhere that I can change. This is Thunderbird 3.0 Thanks Mark

• Microsoft Word 2010 Header and Footer assistance

  - by CBP

  I am using Microsoft Word 2010 to format a book. I need different headers for different parts of the book. I have put them in different sections but my problem is when I click on Header to change or delete certain headers it changes the pages around in my document. For instance when I am looking at the page regularly the writing and section for page 20 is different then the writing and section when I am looking at it with the header and footer open. This is very frustrating because I can not properly change the headers. I hope this makes sense and somebody can explain what is going on and how to resolve this!

• External USB Fingerprint Reader for Pre-boot Authentication for Dell Laptop

  - by cop1152

  My company just purchased several Dell Latitude E6500 laptops with docking stations and external monitors. These laptops have a fingerprint scanner located next to the keyboard. DOCKED users who prefer to use the included fingerprint scanner for pre-boot authentication are forced to open their laptop in order to access the scanner. This is an inconvenience when the laptop is docked. We are looking for an external, usb fingerprint scanner, that will work with the current preboot authentication setup. I assume that this scanner would have to access the existing credentials for authentication....wherever they are stored. So we would require something that would work PRE-BOOT, use the existing credentials, and not interfere with usage when the machine was not docked, such as when the laptop is being used at home. Does anyone have experience with this scenario? Thanks.
