• Laptop changes closing lid power options based on media/music playing

  - by Backdraft

  Hi, This is on a Lenovo X60 running Windows 7 Professional. This is just a pet peeve of mine, but I was wondering if it were somehow possible to have my laptop autodetect whether any media/music is playing on and change/switch the "Close lid" options under Power Options, ie. when something is playing change state to "Do Nothing" otherwise change state to "Sleep". I guess I can probably set a some key combo up with AutoHotKey to do it, but was hoping Windows could detect and switch my Power Options automatically. Thanks.

• REST-based file server

  - by Chris Wenham

  I need to be able to PUT files and GET them later using nothing but HTTP, so I went searching for something that might match the terms "REST file server" or "HTTP file server" or "REST drop-box", etc. Unfortunately, these terms bring up the wrong kind of results on Google. What I want is the equivalent of an SMB fileshare over HTTP. Some ideal features: Can PUT a file of any type at http://servername/service/any/path/I/want/document.pdf Anyone with access can GET that file at the URL I PUT it at Supports AV scanning on any new file that has been PUT Supports DELETE of existing resources (files) Our shop runs Windows, but I'd be interested to know about Unix software that can do this kind of thing, too. It's to be used in an IT department for private users only. It won't be on a public-facing IP address. Does anything like this exist?

• IE9 HANGS: jquery based webapp hanging ONLY with IE9

  - by Daniele B

  I'm stuck on this issue since days... This is the site I'm talking about. It is a webapp which makes large use of backbone, visualsearch, jquery plugins. This website is not working at the moment with IE8, but it's fine that it works with IE9...if just it would! What happens is that the website hangs when loaded ONLY with IE9 and (this is bizarre!) if the profiler tool of IE9 developer tools is ON it doesn't!! It also happens to oher people (I was notified of that) so I'm pretty sure it's not an issue linked to my browser settings. It makes me think about an error which has something to do with delays, or iterative functions which, in presence of profiler, are forced to delay bte cycles and so to leave free time slots to other functions which render the page. I can update with more details if needed. thanks.

• Tree structured troubleshooting survey which gives solution based on answers

  - by japie1001

  Is there some online tool which let me design a tree structured questionaire/survey which suggests a solution to a problem. Example troubleshooting survey for the problem of black monitor screen: Q1: Is the powercable connected to the monitor? 0 Yes 0 NO If answer is no: "The solution to your problem is to connect the power cable" If answer is yes: Contiue with Q2 Q2: Is the computer turned on: 0 yes 0 no etc Is there something like Google Forms where I can achieve this with online?

• How can Nagios handle non-threshold based plugins?

  - by FliesLikeABrick

  I am writing a Nagios plugin to monitor trends of a certain storage resource utilization (e.g. gradual increases are fine, but an instantaneous/sudden increase or decrease in resource usage may indicate a problem). For what it's worth, it is reviewing the last N entries in an RRD file generated by a custom cacti data source/templates. What is the "right" way to handle Nagios notification config/implementation for this? The problem is that it the plugin would exit as warning/critical for one polling period, but in the next it would be fine (or 3 polling periods later, if I look at 3 polling periods worth of data). I guess the question is: should I just write it in such a way that it will alert for X polling periods, or should I find a way to write it such that manual intervention is required for it to clear (such as logging into the monitoring server or hitting a URL to run a script that submits a passive result)? Your input is appreciated, and if you have any tips for how to implement the latter I'm open to them (I can think of a few ways to possibly implement it)

• Virtual machine management on windows using vagrant and veewee [closed]

  - by Aidan

  I wish to use vagrant and possibly VeeWee to construct and maintain virtual machines to automate some testing of servers etc. I am having problems getting them up and running on windows. Is there any are there any takes-nothing-for-granted setup blog posts or instructions anywhere? I live in a Microsoft world so all this Ruby/Git is new (and exciting!) to me but it does mean that I could do with everything being spelled out to me in excruciating detail! Cheers

• Choose relayhost based on the postfix smtpd instance

  - by Zizzencs

  I'd like to setup a postfix host (using RHEL 5.4's default postfix, which is version 2.3) with the following characteristics: an SMTP listener listens on 10.0.0.1:25 and relays all e-mails to 10.0.0.1:2525 an SMTP listener listens on 10.0.0.1:2525 and relays all e-mails to 10.0.0.2:25 Basically the challenge here is to use two different relayhosts for the different SMTP listeners. Is it possible? Is there a better solution to achieve similar behavior?

• System and Router configuration for setting up a home firewall based on Zentyal

  - by Ako

  I am not much of a system administrator, so please be patient if this looks too simple for you. I have a several computers at home, and all of them connect using an ADSL modem/router (and Wireless AP). I have been attacked several times (mainly from Russia and Ukraine), so I thought I should have some kind of firewall, besides the ESET firewall on my Windows 7. So now I have these (new) configuration: I have a small ADSL modem (Zyxel brand) which has only one Ethernet port. This modem is used to connect to internet and is configured in NAT mode. The interface has is configured with IP address 192.168.1.1. I have an old PC and I have installed zentyal on it. It has two Ethernet ports, eth0 and eth1. Eth0 is connected to the Zyxel modem with IP 192.168.1.2 and is checked as the WAN interface (external). I have another ADSL modem which is also a router with 4 Ethernet ports and Wireless AP. One of the Ethernet ports is connected to eth1 on Zentyal box. The Ethernet port's IP is 192.168.2.1 and Zentyal's eth1 is 192.168.2.2. Now, I want to enable other computers to connect to internet through the router both using Wireless and Ethernet. The problem is that I don't know how to configure the router so it routes connections to the Zentyal box. Does anyone have any clue? Again I am sorry if this looks stupid. Thanks.

• Articles of x386 and later CPU based systems

  - by user32569

  Hi there. I know this is hard question, and possibly not to be answered here, but if there is some article, or more you know about, please post a link. About books, its sad but many great computer books cannot be bought in my country. So, you can find many articles online, which says how memory was mapped back in pre x386 CPU. How there was explicit holes ready for MMIO BIOS, Video BIOS, etc. How there was A20 line for allowing higher memory access etc. Problem is, time changed. Today BIOSes are many times larger, and pure x86 16bit mode is used for booting and ROM flashing only. OS ignore BIOS as they access everything using drivers. And I just want to know, how it works today. I know not so specific question, but I read OS dev wiki, many articles, but all refering to days before massive usage of pure 32bit CPUs.

• Excel 2007: Filtering out rows in a table based on a list

  - by Sam Johnson

  I have a large table that looks like this: ID String 1 abcde 2 defgh 3 defgh 4 defgh 5 ijkl 6 ijkl 7 mnop 8 qrst I want to selectivley hide rows by populating a list of filterd values. For example, I'd like to filter out (hide) all rows that contain 'ef', 'kl', and 'qr'. Is there an easy way to do this? I know how to use Advanced filters to include only the rows that contain those substrings, but not the inverse. Has anyone does this before?

• JavaScript-based applications and text browsers

  - by Vi

  How to use complex AJAX applications with a lot of menus and with X.509 authentications in non-GUI mode with simple browsers? For example, I can login to Webmoney from console using links/lynx/link2 (but not w3m), entering captcha (using aaxine) and do operations there, but can't login not using X.509 certificate (even if I try to separate SSL part using "socat tcp-l:... openssl:...:443,cert=extracted_from_firefox.pem") Is there some program that behaves like fully-fledged browser (build DOM/execute JS/Support all features except of actually displaying things), but without GUI and dependencies on GUI libraries?

• SSLVerifyClient optional with location-based exceptions

  - by Ian Dunn

  I have a site that requires authentication in order to access certain directories, but not others. (The "directories" are really just rewrite rules that all pass through /index.php) In order to authenticate, the user can either login with a standard username/password, or submit a client-side x509 certificate. So, Apache's vhost conf looks something like this: SSLCACertificateFile /etc/pki/CA/certs/redacted-ca.crt SSLOptions +ExportCertData +StdEnvVars SSLVerifyClient none SSLVerifyDepth 1 <LocationMatch "/(foo-one|foo-two|foo-three)"> SSLVerifyClient optional </LocationMatch> That works fine, but then large file uploads fail because of the behavior documented in bug 12355. The workaround for that is to set SSLVerifyClient require (or optional) as the default, so now the conf looks like this SSLCACertificateFile /etc/pki/CA/certs/redacted-ca.crt SSLOptions +ExportCertData +StdEnvVars SSLVerifyClient optional SSLVerifyDepth 1 <LocationMatch "/(bar-one|bar-two|bar-three)"> SSLVerifyClient none </LocationMatch> That fixes the upload problem, but the SSLVerifyClient none doesn't work for bar-one, bar-two, etc. Those directories are still prompted to present a certificate. Additionally, I also need the root URL to accessible without the user being prompted for a certificate. I'm afraid that will cancel out the workaround, though.

• Windows Firewall rule based on domain name instead of IP

  - by DennyDotNet

  I'm trying to allow a service to a set of machines via Windows Firewall. I'd like to add my home machine to the firewall but my home machine has a dynamic ip address. I use dyndns so that I have a hostname which I can always connect to. So I'm trying to see if there is a way I can use my hostname instead of an IP. Thanks Update Let me add a little more information, perhaps there are other ways to resolve my issue. The server is a web server hosted by RackSpace. I only want to allow RDP access from my work (static IP, so no problem) and home (dynamic). My home IP doesn't change too often, just often enough to annoy me. So maybe there is a better way to do this... maybe VPN?

• Set origin for forwarder based on virtual domain in Postfix

  - by Andrew Koester

  I currently have a machine set up to operate with two domains. The main name uses the standard Unix-user delivery, and the second domain is entirely virtual (using virtual_alias_domains and virtual_alias_maps), with the second domain only forwarding mail. However, when mail is forwarded, it still appears to be delivered by the host of the primary domain (presumably set by myorigin.) Is it possible to get it so when mail is forwarded to the virtual domain, it appears to be delivered by it as well? That domain is on another IP and I'd like to use it so the mail stays consistent. Thanks.

• Tool to make screenshot-based "screencast"

  - by liori

  Hello, I'd like to make a simple animation: some screenshots with added text. Something like screencast, but simpler, no audio... and hopefully very quick to produce--this is my main requirement. Googling for "screencasts" gives me full-blown tools to record video and audio, and I don't need them. I can make screenshots manually, then add text in GIMP... but maybe there is something easier, quicker? Very preferably something that works on Linux.

• Is there an FTP client for Windows 7 with a text-based UI? (not text-prompt based, like ftp.exe)

  - by Alan B

  Is there such as thing as a text-mode FTP client for Windows 7 ? By 'text-mode' I mean one that runs in a CMD.EXE window as opposed to a Windows GUI application. It also needs to be something along the lines of FileZilla, i.e. menu-driven as opposed to command-entry clients like NcFTP or indeed the built-in one. edit: To avoid confusion, what I mean is an application similar to that pictured (ZTreeWin File Manager), which runs from CMD.EXE and uses text characters for its UI, within the CMD.EXE window. The built-in FTP client, and things like NcFTP offer a prompt at which you issue commands. That's not what I'm looking for.

• Ubuntu based VPN server behind NAT router?

  - by maartenn88

  I have a small intranet- and file-server inside our company, which can only be reached from inside our own network. I'd like to be able to reach the intranet and files on the server from outside the network, however I don't really like the idea of completely opening security by forwarding the ports on our NAT-router, so I'd prefer to enable a VPN possibility for this. So I have a router, which is the DHCP server and has NAT function, and I have an Ubuntu Server with the files and intranet on it. How do I configure these two so that I can make a VPN connection with my network in order to reach the server? thanks in advance for any answer!

• Fill down in Excel, but based on multiple values

  - by Jenn D.

  I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

• Deleting entire lines in a text file based on a partial string match with Windows PowerShell

  - by Charles

  So I have several large text files I need to sort through, and remove all occurrences of lines which contain a given keyword. So basically, if I have these lines: This is not a test This is a test Maybe a test Definitely not a test And I run the script with 'not', I need to entirely delete lines 1 and 4. I've been trying with: PS C:\Users\Admin> (Get-Content "D:\Logs\co2.txt") | Foreach-Object {$_ -replace "3*Program*", ""} | Set-Content "D:\Logs\co2.txt" but it only replaces the 'Program' and not the entire line.

• Prevent member of administrator group loging in via Remote Desktop

  - by Chris J

  In order to support some build processes on our Server 2003 development servers, we require a common user account that has administrative privs. Unfortuantly, this also means that anyone that knows the password can also gain admin privs on a server. Assume that trying to keep the password secret is a failed exercise. Developers that need admin privs already have admin privs so should be able to log in as themselves. So the question is a simple one: is there anything I can configure to prevent people (ab)using the account to gain administrator on servers they shouldn't have administrator on? I'm aware that devs could disable anything that is put in place, but that's then down to process and auditing to track and manage. I don't mind where or how: it can be via the local security policy, group policy, a batch file executed in the user's profile, or something else.

• Client side certificates in client browsers with unix server for management

  - by user146253

  We are currently running Unix dedicated servers for everything (Web cluster, database, FTP, batch, ...) except for a Microsoft Active Directory Certificate Services. The sole purpose of this Windows box is to provide client side certificates to our clients browsers. All our clients are required to install a client side certificate on order for them to be able to access our website. Is there an alternative in the Unix space? The purpose is to make sure only the approved hardware of an approved client can access our website. I'm open for any solution that provides me with this level of security. We are however talking about thousands of certified computers just so you can factor that in in a proposed solution. Optionally we would also like to be able to revoke access. With Regards.

• Free, web based alternative to Visio?

  - by Lars

  I have used Visio to map out my network structure, and have used the export function to create an HTML page that is searchable by IP, hostname etc. This is a really nice tool and I use it often. However, I would like for users who do not use Internet Explorer to be able to use the search features. What are some alternatives to Visio here? I want to draw a network diagram where objects are searchable. Thanks!

• Dead-simple USB-based Windows partition cloner?

  - by OverTheRainbow

  Clonezilla is a fine open-source tool, but it requires going through several screens. Since I need to save/restore the same Windows partition, I was wondering if someone knew of a tool (open-source or not) that is easier to use and boots off a USB keydrive. Ideally, it'll save the two commands to save/restore a partition, so I just need to boot the host from the USB key, choose the command, and it'll take care of business. Are there solutions that look like this? Thank you. Edit: Here's one among other articles that shows how to tell CZ to run a script to avoid the multiple screens.
