• Can't detect wireless networks, running ubuntu 9.10 on eeepc 1000he

  - by David Brown

  Hi, I am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them). Any help at all will be greatly appreciated! I googled quite a bit and talked to a human about this but could not fix it. We tried dhclient ra0, which returned There is already a pid file /var/run/dhclient.pid with pid 2438 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.2 Copyright 2004-2008 Internet Systems Consortium.

• Task manager: Windows XP RAM usage doesn't add up

  - by David Oneill

  When using the task manager in Windows XP Pro, the amount of RAM that is listed as being used by the individual processes is not adding up to the total memory used (as listed by the total commit on the performance page). The total sum of all the RAM being used the the processes: 195604 K The amount in use as listed by performance page and the status bar: 280028 K 1) Why is this? 2) How do I reduce the amount of memory used?

• WAMP server not starting and a mystery service is using port 80

  - by David Gard

  I'm using WAMP on Windows 7 and tonight I'm unable to start it (it's been working fine for about 3 years previously). I first checked the logs, but nothing in there. So I checked the Windows Event Viewer (eventvwr), where I saw 2x errors for each attempted start - The Apache service named reported the following error: (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80. The Apache service named reported the following error: no listening sockets available, shutting down. After this, I opened the command prompt and ran netstat -a, and to my surprise there were 3 entries for port 80 - Prot   Local Address  Foreign Address   State TCP   127.0.0.1:80       MyPCName:53831   TIME_WAIT TCP   127.0.0.1:80       MyPCName:57834   TIME_WAIT TCP   127.0.0.1:80       MyPCName:57839   TIME_WAIT From here, I'm kind of lost. As far as I can tell, something is utalising port 80, but I don't know what or why. If anyone is able to suggest what I might do next I'd be most greatful. Thanks.

• Used HDD/ran DiskSmartView/40,000 Power-on-hours?? should i trust it w/ my data, or take it back and bitch?

  - by David Lindsay

  I just bought a used hard drive from a University Surplus Store. Decided to run DiskSmartView to make sure it wasn't ready to fail. 40,000 power-on-hours I don't know if I feel like trusting my data to something that used. I really dont know if thats unreasonably old, but when i compare it to the POH reading i get when testing my other hdds its more than 3x older (my others have 2110 hours, 6150 hours, etc.. It's a Western Digital, so that gives me a little bit of hope(WDC WD4000KD-00NAB0). I could sure use someone else's opinion here. Thanks, DAVE

• How can I compare two directories to compare missing files, when the directories don't have the same structure?

  - by David Dean

  I've been sent a HDD of new and updated files from an organisation that we are working with, but we already have most of the files sitting on our servers, and would like to update our local versions to match theirs. Normally, this would be a job for something like rsync, but our problem is that the directory structure they provide is very poorly organised and we've had to rearrange their files in the past to work best with our systems. So, my question is: How can I find out which files in the set they have provided are new or different to the versions that we have, when the directory structures are different? Once that question is answered, we can update the changed files, and work out where to put the new files on our system, probably somewhat manually.

• Paste string of date format mm/dd/yy to iWork-Numbers

  - by David.Chu.ca

  I have trouble to paste a list of strings in the format of 'mm/dd/yy' into iWork-Numbers. For example: 04/01/10 04/03/10 04/13/10 The result will be: 2004-01-10 2004-03-10 04/13/10 It looks like that Numbers convert the mm into year, then month and last day. Is there any way to paste whatever as they are? Do I have to change settings in Numberers or System preference?

• Copy iMovie 11 project from one account to another user account?

  - by David.Chu.ca

  I have one user account as admin with several iMovie projects. After a period of time, I created a standard user account. Now I want to move admin user's iMovie projects to standard user. What I tried was to copy admin's Movies folder content to standard user by dropping to standard user's public shared dropbox. Then I copied the content to standard user's Movies folder. However, I cannot see iMovie projects in standard user by iMovie app. Is there anyway to move projects from one user to another user? Or copy one user's data to another user? Not sure if I missed anything if just copying Movies folder?

• Why does terminal prompt text becomes black when connecting to Ubuntu with Nomachine NX client?

  - by David B

  I'm using Nomachine NX client for Windows to remotely connect to my Ubuntu. Every now and then I experience a strange phenomena: the text in the prompt of all open terminal windows becomes black, so it can't be viewed over the black background. Typed commands are also black, but the results are in normal colors. So I can run stuff, but can't see what I'm typing... After I close all open terminal windows and start a new terminal window, everything goes back to normal. This is rerally annoying and happens quite often. Any idea why?

• Setup NTPD in Ubuntu to sync Windows AD

  - by David

  I am setting up my Ubuntu 10.0.4 server to sync clock with a Windows 2008 AD.

• WS2008 NTP - Using time.windows.com,0x9 - Time always skewed forwards

  - by David

  I have a domain controller configured to use time.windows.com (with 0x09 flags set). I've noticed that frequently the systems' clock is fast - it varies from 10 minutes to even 45 minutes. I always have to keep resetting the system date/time back to what it should be. When I run "w32tm /query /source" it tells me it's using time.windows.com, and obviously I trust Microsoft not to serve incorrect times, but why is my server's clock fast? EDIT: There are a few Time-Service events in the System log: Event ID: 142 Message: The time service has stopped advertising as a time source because the local clock is not synchronized. Event ID: 139 Message: The time service has started advertising as a time source. These two messages appear in pairs every hour or so. Event 142 appears 14 to 16 minutes after 139 appears. Going back a few months, these events appear: Event ID: 35 Message: The time service is now synchronizing the system time with the time source time.windows.com,0x9 (ntp.m|0x9|0.0.0.0:123-65.55.21.21:123). Event ID: 37 Message: The time provider NtpClient is currently receiving valid time data from time.windows.com,0x9 (ntp.m|0x9|0.0.0.0:123-65.55.21.21:123). Event ID: 47 Message: Time Provider NtpClient: No valid response has been received from manually configured peer time.windows.com,0x9 after 8 attempts to contact it. This peer will be discarded as a time source and NtpClient will attempt to discover a new peer with this DNS name. The error was: The time sample was rejected because: The peer is not synchronized, or it has been too long since the peer's last synchronization. These three events only appear once in the log, back in October.

• Enable FTP Publishing on IIS7?

  - by David Lively

  I've followed the steps in http://learn.iis.net/page.aspx/303/adding-ftp-to-a-web-site/ However, when I get to the part where it says to click "add ftp publishing to website", the option is not visible in the IIS management console. I've verified that the "FTP Publishing Service" is installed in the server manager, and I can see it running in the services applet and via netstat -a. Suggestions?

• Tools for load-testing HTTP servers?

  - by David Wolever

  I've had to load test HTTP servers/web applications a few times, and each time I've been underwhelmed by the quality of tools I've been able to find. So, when you're load testing a HTTP server, what tools do you use? And what are the things I'll most likely do wrong the next time I've got to do it?

• How to block outside network access on a windows 2008 server

• ScreenOS MIP selection for outbound connections

  - by David Mackintosh

  Given a ScreenOS 6.3.0 firewall with this configuration: unset flow reverse-route clear-text set interface "ethernet0/0" zone "Trust" set interface ethernet0/0 ip 192.168.1.1/24 set interface ethernet0/2 ip 10.0.0.1/24 set interface ethernet0/2 mip 10.9.9.10 host 192.168.1.10 netmask 255.255.255.255 vr trust-vr set interface ethernet0/2 mip 10.8.8.10 host 192.168.1.10 netmask 255.255.255.255 vr trust-vr set route 0.0.0.0/0 interface ethernet0/2 gateway 10.0.0.254 ... (and assuming appropriate policies) is there a way to control which MIP the firewall selects for outbound connections initiated by 192.168.1.10? (presumably because I want the upstream 10.0.0.254 to do different things with the packet depending on what its source IP is). Update: OK, my scenario is this: I have two ISP uplinks, each giving me a different IP space. Each ISP will only route the IP space they have assigned me. So in order for the server to be reachable by both ISPs, I need two MIPs for the same server, one on each interface. Inbound traffic will work fine with the 'unset flow reverse-route clear-text' option in use. But for outbound (think an email server sending a message) I need a way to select an appropriate MIP depending on which outbound link I want the system to use, and I want this to be resiliant so that if the link the firewall prefers goes down overnight I don't have to manually flip something to keep the mail flowing. Basically I'm trying to avoid having to buy a link-balancer appliance (or two since I'll need a cluster). Is there a way to do this?

• unzip file on small drive

  - by David Oneill

  I have a zip file that contains many files. Each file in the zip file is about 100MB, and is compressed about 10% (IE it is about 90MB in the zip file). The whole zip file is 20GB, and I'm trying to unzip it onto a drive that has only 30GB free. On Windows 7, how can I unzip a zip file on my laptop's harddrive that doesn't have enough space for both the zipped and unzipped copies of the file? IE can I tell windows to remove stuff from the zip file as it is uncompressed?

• Outlook 2007 "Mark as Not Junk" Dialog Confusion

  - by David

  Outlook 2007's "Not Junk" button opens the "Mark as Not Junk" dialog. The dialog works correctly if I keep the "Always trust e-mail from <email address>" option checked. That is, the message is removed from the Junk folder and returns to the Inbox. However, if I uncheck the "Always trust" box, pressing OK dismisses the dialog, but nothing else happens. Why not? According to Outlook help, "When you mark a message as not junk, you are given the option of adding the sender or the mailing list name to your Safe Senders List or Safe Recipients List." That sure makes it sound like this is just an option, and not necessary for the core functionality of the action. I really don't want to trust a (possibly forged) From: address, but I do want my mail back in the Inbox. I could manually drag it, but I'm assuming that marking a message as not junk also trains some kind of bayesian filter. Am I mistaken? Thanks.

• MMC crashes on Windows Server 2008 x64 - Exchange console, event viewer

  - by David M Williams

  Help! I don't know what happened; this server has been very reliable but suddenly began having problems with a particular .NET 2.0 web site simply hanging - it wouldn't load at all. However, another ASP.NET site was still fine. Reinstalling the site didn't fix it, nor did deleting and re-creating the application within IIS. Trying the event viewer was met with a horrifying "Microsoft Management Console has stopped working". Some Googling led me to believe the .NET framework was the problem. I found a tool called the .NET cleanup tool - http://blogs.msdn.com/astebner/pages/8904493.aspx - which cleaned out .NET entirely. I reinstalled .NET 1.1 and 3.5 (which installed 2.0 and 3.0 as well). Using the .NET verification tool - http://blogs.msdn.com/astebner/pages/8999004.aspx - I believe these have all installed ok. However, my server is in worse shape now. The Exchange 2010 Management Console crashes with an MMC error and now my other (previously reliable) .NET web app now hangs on loading too. I thought I should use Computer Management to remove and re-add the application and web server roles but sure enough, MMC crashes. If anyone can help I will be extremely grateful. Thank you !

• Changing DFS link location from command line

  - by David Collantes

  I have the following AD DFS (Windows 2003 R2): DFS Root name: members DFS Link: me DFS Link Target: \\myserver\meshare DFS Link: you DFS Link Target: \\myserver\youshare I need to change all the link targets to \\theirserver, while keeping everything else the same. I have created the shares meshare and youshare on \\theirserver already, with the files they will hold. How to accomplish this from command line (I will batch it)? Will "dfscmd /move" be the command to use? If so, what would the exact syntax be?

• IIS seems to send email twice

  - by David Brunelle

  Hi, we have a request page in our website that send email to confirm the request. It seem that whenever this page is accessed, some (not all of them) are sent more than once at different time, sometime hours apart. The code (which is an old ASP page) looks fine as it sends only once to the recipient. So I doubt it's a programming related problem. When looking at the Exchange server, the tech told me that he seems to be receiving the request twice at different time, so the problem comes from what's between the code and Exchange. My hypothesis is that IIS seem to 'remember' the page and rerun it for some reason. Any hint on where to start? We have IIS 6 (in french if it makes any difference) with Exchange 2007. IIS is running on a Windows Server 2003 machine (virtual machine I believe) in a DMZ. I don't know about Exchange. Thank you.

• Looking for speech-to-text tool (convert .wav to text)

  - by David

  I have the ability to get .wav files of voice mails emailed to me, but sometimes I'll be sitting in a meeting and I need to know the content of a message without playing it out loud. Are there any good (and, preferably, free) tools for converting .wav files to text? I know Google Voice has this capability, but I can't determine if it'll work on a file-by-file basis. I realize that this is a difficult research problem, but even an 80% solution might be workable.

• CPU installation

  - by David Oneill

  I'm in the midst of building a computer (this is my first time). When I first put the heatsink on the CPU, I was a little off center. Some of the thermal compound came off, so when I re-centered it, it isn't completely evenly distributed. So here's my question: how picky are CPUs in terms of how evenly the thermal compound is? Should I take it apart, clean it, and apply a new layer of compound? Or can I just keep an eye on the CPU temperature? (I'm not overclocking or anything, if that matters)

• I Can Edit SD Card on Windows XP but Not on Windows 7

  - by David C

  I have an 8GB SDHC card which I have used to upload pictures onto my Windows XP machine using an SD card reader ("SanDisk Ultra II"). I could also delete pictures and create folders on the card. I recently obtained a new computer that runs Windows 7 and, while I can view and upload the photos, I am unable to delete photos or create folders. When I attempt to do either of these two operations, the desired option does not appear in the menu ("Delete"/"New Folder"). Also, the shortcut keys do not work (e.g. the Delete key and Alt+F+W+F). I have attempted to change the Properties from Read-only, but am greeted with a "media is write protected". I should add that when I insert the Card Reader back into my Windows XP computer, I am granted full write permissions. Why can't I modify the SD Card from Windows 7? And, related, how can I fix this issue? Let me know if you have any additional questions. Thanks!

• How do I get the line of a javascript error in a Chrome Web Developer stack trace?

  Using Chrome Web Developer, I am analyzing a complex web page linking many javascript files. Web Developer console notes that there is a bug in the javascript. I click on the bug notice in the console, which leads me to a line in a javascript file that I have no control over and did not code. However, I want to trace this error to a line of javascript that I did write in a different file. How do I do that?

• Have rTorrent to move .torrent files

  - by David Alvares

  I am running rTorrent 0.9.2 and have configured it to move completed torrents to a different folder with this configuration line: system.method.set_key = event.download.finished,move_complete,"d.set_directory=~/done/;execute=mv,-u,$d.get_base_path=,~/done/" This is working fine, but I would like it to also move the .torrent file that it creates (from a magnet link into the session directory) into this done directory with the same name as the torrent and a .torrent extension. I tried adding another cp command, but I can not seem to figure out which variable ($d.get_hash did not work) stores the torrent's hash (which is what the .torrent files are named in the session directory). Is there a way to do this with rTorrent, if so how?
