  • Make Nginx fail when SSL certificate not present, instead of hopping to only available certificate

    - by Oli
    I've got a bunch of websites on a server, all hosted through nginx. One site has a certificate, the others do not. Here's an example of two sites, using (fairly accurate) representations of real configuration: server { listen 80; server_name ssl.example.com; return 301 https://ssl.example.com$request_uri; } server { listen 443 ssl; server_name ssl.example.com; } server { listen 80; server_name nossl.example.com; } SSL works on ssl.example.com great. If I visit http://nossl.example.com, that works great, but if I try to visit https://nossl.example.com (note the SSL), I get ugly warnings about the certificate being for ssl.example.com. By the sounds of it, because ssl.example.com is the only site listening on port 443, all requests are being sent to it, regardless of domain name. Is there anything I can do to make sure a Nginx server directive only responds to domains it's responsible for?

  • Quick, Linux-compatible unit-aware calculator

    - by endolith
    I want to be able to press a keyboard combination, start typing a mathematical expression that includes units and slightly advanced math (not just a four-function calculator), and get a result immediately, in units that I specify, that I can copy and paste. Currently I open Firefox and press Ctrl+K, type in the search box, and it usually gives me a result in the drop-down from Google Calculator. It doesn't always, though, so I press "=" at the end, wait for a result, remove the equals, wait for a result, realize it doesn't understand the way I typed a unit, open the result in a new tab, etc. it sucks. Wolfram Alpha is smarter, but very much slower, and the output is all images, not text, and I don't have a quick widget for it, if such a thing could even exist. GNU units has a ton of units, which is great, and I can define my own units, which is great, but they have to be written in specific, unintuitive ways, it doesn't handle much advanced math, and I'd need to open a terminal, start units, etc. I hate the command line. I wasted a lot of time trying to make front-ends for units in Deskbar and Launchy, but I'm not a real coder and I don't use either of those anymore. Any other solutions or enhancements of these?

  • Any way to move Office Starter To-Go to a non-flash drive?

    - by Scott Bussinger
    Microsoft's Office Starter edition has an interesting option to create a portable version on a USB flash drive using the "Microsoft Office Starter To-Go Device Manager". This creates a portable version of the Word and Excel starter editions (limited versions of the normal applications that include ads). This would be great for use in Virtual Machines since it requires no registration and has a perpetual license. But I want to copy the files off of the flash drive and just store them in the VHD. The problem is that it appears when you try to run the office.exe executable from anywhere but the USB drive you get the error "Microsoft Office Starter To-Go cannot be launched because it is installed on an unsupported device." Any ideas what it is objecting to and is there a legal workaround for this? A limited but legal and portable version of Word and Excel is a great idea. But tying it specifically to a USB flash drive seems a bit odd. They don't seem to care how many of those flash drives you create so it's not clear what the restrictions are about.

  • Access 2007: How can I make this EXPRESSION less complex?

    - by Mike
    Access is telling me that my new expression is to complex. It used to work when we had 10 service levels, but now we have 19! Great! My expression is checking the COST of our services in the [PriceCharged] field and then assigning the appropriate HOURS [Servicelevel] when I perform a calculation to work out how much REVENUE each colleague has made when working for a client. The [EstimatedTime] field stores the actual hours each colleague has worked. [EstimatedTime]/[ServiceLevel]*[PriceCharged] Great. Below is the breakdown of my COST to HOURS expression. I've put them on different lines to make it easier to read - please do not be put off by the length of this post, it's all the same info in the end. Many thanks,Mike ServiceLevel: IIf([pricecharged]=100(COST),6(HOURS), IIf([pricecharged]=200 Or [pricecharged]=210,12.5, IIf([pricecharged]=300,19, IIf([pricecharged]=400 Or [pricecharged]=410,25, IIf([pricecharged]=500,31, IIf([pricecharged]=600,37.5, IIf([pricecharged]=700,43, IIf([pricecharged]=800 Or [pricecharged]=810,50, IIf([pricecharged]=900,56, IIf([pricecharged]=1000,62.5, IIf([pricecharged]=1100,69, IIf([pricecharged]=1200 Or [pricecharged]=1210,75, IIf([pricecharged]=1300 Or [pricecharged]=1310,100, IIf([pricecharged]=1400,125, IIf([pricecharged]=1500,150, IIf([pricecharged]=1600,175, IIf([pricecharged]=1700,200, IIf([pricecharged]=1800,225, IIf([pricecharged]=1900,250,0)))))))))))))))))))

  • AutoHotkey - Organizing hotkeys so as to use Several hotkeys optimally

    - by Stenemo
    My question is how to structure key combinations in script below most effectively using AutoHotkey. Having searched for exactly how to do this for hours I figured I should post here so others can at least find this solution if they are trying to do the same: http://www.autohotkey.com/board/topic/90013-solved-wasd-fna-left-fnalta-home-fnctrla-ctrl-left-etc/ and How to combine three keys as a hotkey with Autohotkey? My Question is how to use this method most effectively, and is not answered in those threads. My idea would be to use this for everything related to up (etc), e.g.: ; Up Combinations: Ctrl Up, SHIFT + Up, SHIFT + Ctrl Up, [Alt/win + Up easily added and organized using this system] CapsLock & w:: GetKeyState, stateCtrl, LCtrl GetKeyState, stateShift, LShift GetKeyState, stateWin, LWin GetKeyState, stateAlt, LAlt if stateCtrl = D if stateShift = D if stateWin = D Send ^+#{Up}; Ctrl + SHIFT + Win + Up else Send ^+{Up} ; Ctrl + SHIFT + Up else if stateWin = D Send ^#{Up} ; Ctrl + Win + Up else Send ^{Up} ; Ctrl Up else if stateShift = D Send +{Up} ; SHIFT + Up else if stateWin = D Send #{Up} ; Win + Up else if stateAlt = D Send !{Up} ; Alt + Up else Send {Up} ; Up return Also, if there is a better way to do this, that would be great. E.g.: *CapsLock & w:: send {Up} Does almost exactly the opposite of what I want (sends up even if other modifiers are held down). When I hold e.g. control at the same time, I want it to do control + up. Have I missed such a AutoHotkey command? If anyone has a better way to do this that would be great.

  • SCCM 2012 Clients no longer detecting

    - by user3685428
    Here is the scenario I had a fully functioning SCCM 2012 site server with the DP, MP, SUP, Application catalog, etc. roles configured and working. There is only one server on this site. Everything was great but i was not happy with SUP, so i decided to create a separate WSUS server and configure Windows Updates through GPOs. That setup worked great as well so i went ahead and removed the SUP role from SCCM and removed the WSUS feature from my SCCM server (they were configured on the same SCCM Server). I did not notice any problems right away. A couple days later i noticed that the OSD deployments were giving errors, and after a couple hours of trying suggestions from Google, i was able to uninstall PXE and make a few changes and reinstall with WDS to get it working again. Again, thought everything was fine and continued on. The last couple days i have noticed that any new machine deployed or installing the Client will show in the SCCM console as "No" Client. The client machines will show connected to a site but the software center shows "IT Organization" instead of our site like the previous clients. The existing clients all seem to be functioning normally. they still receive application distributions and configuration baselines, etc. Reinstalling, uninstalling and reinstalling, repairing does not fix the problems and this happens on all new clients. ClientLocation.log shows it connecting to the correct MP. Nothing odd in any of the logs except for the ClientMessaging.log which repeats continuously this line: <![LOG[Raising event: instance of CCM_CcmHttp_Status { ClientID = "GUID:0450fde3-ab82-41bf-9c33-87a18113744b"; DateTime = "20140528214824.993000+000"; HostName = "SOUNDWAVE.domain.org"; HRESULT = "0x00000000"; ProcessID = 4092; StatusCode = 0; ThreadID = 3720; }; ]LOG]!><time="16:48:24.994+300" date="05-28-2014" component="CcmMessaging" context="" type="1" thread="3720" file="event.cpp:706"> thanks

  • Understanding Exchange User Monitor (ExMon) Output

    - by SturdyErde
    I recently downloaded and ran ExMon while trying to troubleshoot Outlook connectivity problems due to high CPU usage on Exchange Server 2010 SP2 UR8. The tool provides a great set of data, but I have not yet figured out how to make great use of it. My first question is why the Exchange Server itself shows up as a high-use MAPI client in the ExMon data. Among the users' client versions I see build numbers listed for Outlook 2013, 2010, and yes, even 2007 clients. I also see build number 14.2.387.0, which represents Exchange Server 2010 SP2 Update Rollup 8 (+/- some other patch that makes it not quite match the UR8 number). There are many user rows that list only "::1" and/or the short hostname of my Exchange server in the 'Client IP Addresses' column. Some other columns include the end-user's actual IP address and the Exchange server's IP address. ExMon shows that it is actually Exchange Server that is utilizing the highest percentage of CPU that is used for MAPI calls. I had expected to see 1 IP address and version number for each user reported by ExMon. Instead, most records show multiple version #'s (Exchange ver and Outlook ver) and multiple IPs (Exchange IP and client IP). Can anyone explain the reason for this to me, please?

  • VirtualBox: Can't get Bridged Networking to work (Win7 host)

    - by MikeTheTall
    I'm trying to set up a virtual LAMP server, including sharing files between the guest OS (Ubuntu Server) and the host OS (Windows 7) using samba. I think my problem is that I can't get Bridged (or Host-Only) networking to work in VirtualBox. I can boot the Linux VM just fine with NAT, but then can't access any services on it directly (except after port-forwarding port 80)(my understanding is that port-forwarding works because I'm not running a web server on the host OS, and therefore it can forward traffic to the unused port 80). I don't think that port-forwarding samba traffic (from the host to the guest) will work since I think that the host OS is using those ports. When I turn off NAT and turn bridged networking on I get an error. The VM fails to boot, with a dialog popping up (title: VirtualBox - Error) that says "Failed to open a session for the virtual machine UbuntuServer. Configuration error: Failed to get MAC address (VERR_CFGM_VALUE_NOT_FOUND). I'm hoping that once this is resolved then samba will work ok :) Any advice on this would be great (how to fix it would be wonderful, next steps for troubleshooting would be great, too :) )

  • PHP sessions currupt

    - by Baversjo
    Using symfony framework 1.4 I have created a website. I'm using sfguard for authentication. Now, this is working great on WAMP (windows). I can login to several accounts on different browsers and use the website. I have ubuntu server 9.10 running apache (everything up to date and default configuration). On my server, when I login to the website in one browser it works great. When I on my other computer login with another user account on the public website, the login is successful. But when I refresh/go to another page the first user is shown as logged in instead! Also, when I press logout, It's not showing that I'm logged out after page load. When I press f5 again I'm logged out. As mentioned, all this works as expected on my local installation. I'm thinking there something wrong with my PHP session configuration on my ubuntu server, but I've never touched it.. Please help me. This is a school project and I'm presenting it today :(

  • Host Primary Domain from a subfolder

    - by TandemAdam
    I am having a problem making a sub directory act as the public_html for my main domain, and getting a solution that works with that domains sub directories too. My hosting allows me to host multiple sites, which are all working great. I have set up a subfolder under my ~/public_html/ directory called /domains/, where I create a folder for each separate website. e.g. public_html domains websiteone websitetwo websitethree ... This keeps my sites nice and tidy. The only issue was getting my "main domain" to fit into this system. It seems my main domain, is somehow tied to my account (or to Apache, or something), so I can't change the "document root" of this domain. I can define the document roots for any other domains ("Addon Domains") that I add in cPanel no problem. But the main domain is different. I was told to edit the .htaccess file, to redirect the main domain to a subdirectory. This seemed to work great, and my site works fine on it's home/index page. The problem I'm having is that if I try to navigate my browser to say the images folder (just for example) of my main site, like this: www.yourmaindomain.com/images/ then it seems to ignore the redirect and shows the entire server directory in the url, like this: www.yourmaindomain.com/domains/yourmaindomain/images/ It still actually shows the correct "Index of /images" page, and show the list of all my images. Here is an example of my .htaccess file that I am using: RewriteEngine on RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteCond %{REQUEST_URI} !^/domains/yourmaindomain/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /domains/yourmaindomain/$1 RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteRule ^(/)?$ domains/yourmaindomain/index.html [L] Does this htaccess file look correct? I just need to make it so my main domain behaves like an addon domain, and it's subdirectories adhere to the redirect rules.

  • .NET 2.0 Application now running slow on IIS 7.5

    - by Valien
    I recently moved (and still in testing) an application from a Windows 2003 Server (Physical box) running IIS 6.x to a Windows 2008 R2 Standard (VM) IIS 7.5 server. The application is a .NET framework 2.0 application and is running under a 2.0 App Pool. This site works great except for one thing: Takes forever to get a request back. I've been tracking it with Chrome Inspect Element and it queries the site and can take up to 45 seconds to answer. Now when it does the page(s) render instantly but it's that initial request that's killing it. I see no error logs or issues with the application or Windows Event Viewer or even IIS logs so not sure where to start looking next. Some new changes was that previously the app resided behind a Pix firewall and now is behind a larger network environment in a DMZ zone (and I believe NetScaler is also being used to manage the network). I do not have rights/abilities to look at the network itself but can contact the Data center folks to look deeper into this but I wanted to make sure it's not my application that might be causing the slowdown or IIS. In summary: .NET 2.0 application works great in IIS 6.x Application moved to an IIS 7.5 server and now slow on rendering but when it does render responds back with pages instantly. Edit for solution Found out that it was the SOAP calls that were slowing the site down. In the new datacenter my application cannot request SOAP calls and so they time out after 40-45 seconds or so. Now trying to find out if I can install a proxy server to redirect this...

  • how could application installations/configurations be easier in linux?

    - by ajsie
    although you can do anything in linux it tends to require a lot of tweaking in config files and reading a lot of manuals/tutorials before you can have it running in your way. i know that it gets a lot easier by time, and the apt-get installations with ubuntu/debian is heading the right way. but how can linux be more userfriendly for us in the future? i thought that if more is automated like an IDE environment, eg. typing svn will give us all the commands and description about each command when you move between commands with your keyboard. that would be great. but that's just one example. another is the navigation in the terminal between folders. now you have to type a lot just to jump from/to different folders. would be great with some more automatization here too. i know that these extra features will slow down the server, but its 2010 now, and these features are not that heavy for the cpu, but makes it more userfriendly and encourage maintainance of a server, not frighten u off. what do you think about this? should/could we have more user friendly linux environment in servers, something that has annoyed you a lot? a lot of things are done in the unix way, but maybe we should reinvent the wheel in some areas, cause apparently, its so...repeatingly today and difficult to do easy tasks. it should be easier i think..

  • batch copy files with error log on missing permissions

    - by sc911
    Hi *, I'm searching for a tool to batch-copy files, that should support the following points: copy files from a net-share report any errors show errors only or filter log on errors don't stop on an error also report if a file or a folder could not be copied due to missing permissions if possible it should have a queue where new job can be added while copying I tried the following tools: TerraCopy: takes a lot time to just calculate the time and the size of the job and does not report errors due to missing permissions (it doesn't even add those files to the copy-queue) Karne's replicator: does not report errors due to missing permissions xcopy: does a great job when using the right parameters and piping the output to a file (in the German localization xcopy /k /r /e /i /s /c /h SOURCE TARGET>LOGFILE 2>&1 will do the job. opening the logfile in IE will give you a great monitor). but quing jobs it not possible (ok, you can join them all in a batch-file, but you can not queue jobs while another one is running (hm, thinking of a batch-script that loops through a file with the source-target-config...)) to be continued Which tools do you use? Tell me! Thx sc911

  • CentOS 5 VPN Server won't work

    - by Miro Markarian
    I have a CentOS 5 server configured to be both a L2TP server and a PPTP server + a radius server for hosting the AAA. My problem is that, the L2TP works great and I can connect to it, but can't connect to PPTP and every-time it ends up with error #619 when it gets to the verifying username and password section. Here is the log I got from /var/log/messages Dec 17 07:40:02 serverdl pptpd[8570]: CTRL: Client 5.52.247.62 control connection started Dec 17 07:40:03 serverdl pptpd[8570]: CTRL: Starting call (launching pppd, opening GRE) Dec 17 07:40:03 serverdl pppd[8571]: Plugin radius.so loaded.

I believe it must be a radiusclient issue because both of the PPTP and L2TP services use radius to authenticate. And another thing I think must be the issue is that when assigning IPs to the PPP interfaces, I have done the following config. Is that right? For L2TP: localip 10.10.10.1 remoteip 10.10.10.2-254 For PPTP: localip 10.10.9.1 remoteip 10.10.9.2-254

  • Deploy our own software using Puppet?

    - by Ken
    (Apologies in advance for the stupidity in this question. I'm normally a programmer, not a sysadmin, but I've taken it upon myself to automate some things, and clean up some other things which are automated but not in the prettiest way. :-) I've been looking around at various tools for automation of software deployment to a bunch of servers, like cfengine, Puppet, and Chef. So far, Puppet looks the most appealing, but I've certainly not committed to anything yet. These tools all look like they can do a great job of keeping a bunch of servers up-to-date with prepackaged software. What I don't get is: how does one use a tool (like Puppet) to manage deployments of our own internal software? I think I'm at a loss because I've seen a thousand tutorials showing how to keep Apache ensure => latest (which is pretty cool), but nothing that quite corresponds to my use-case today, which is something more like: when a human being pushes The Button, pull branch A from the version-control repository B run command C to compile it copy the binaries D to servers E1 through E10 on each server, run command F to make all changes take effect Puppet sounds great, and I totally see the advantage of declarative, idempotent configuration over some shell scripts, but I've not seen any tutorials for "you want to update your shell scripts to Puppet (or Chef, or cfengine) so here's what you should do". Is there such a thing? Is it obvious to other people how to take the things provided in the Puppet docs and replicate the behavior I want? Am I just not getting it? What it's sounding like to me, so far, is that the human being (#1) would manually package the software (#2 and #3) external to Puppet, manually update the Puppet config, which would trigger Puppet to update the servers ... maybe? (I'm a little confused here, as I'm sure you can tell.) Thanks!

  • HP tx2510us shuts down without warning, now won't boot, no BIOS codes, screen doesn't light

    - by Tim S
    Hey all, HP tx2150us worked great for a year and a half, rarely it would shut down instead of sleeping. It started running hot sometimes, I installed Win7, worked great, still running hot. Before Xmas, it gave me evidence of video errors - jagged lines, rows missing. That same night, it started rebooting, then it shut off and wouldn't boot. It gave me a BIOS code, I shut it off to look up the code online. When I turned it on again, it won't boot at all. The LEDs all light up, the fan, HD, and optical all spin up, but the screen never lights up and it doesn't try to boot, nor does it blink any BIOS codes. It just acts like it's sleeping, and won't wake up. I suspected heat problems, so I disassembled it, cleaned the crap out of the fan, and reassembled it, breaking the stereo mic connector. Oh well. When I reassembled it, it booted up into Win7 again, but kept shutting down for no discernible reason. After a dozen or so random reboots like that, it is now back to where it was - turns on but doesn't boot or give BIOS codes. The screen never lights, and everything spins up then idles. Any ideas? I really can't afford to buy a new one and I use(d) it to take ALL my notes, that's why I got a tablet in the first place.

  • dom0 enable IPv6 for guests

    - by user98651
    I am looking at deploying IPv6 to my virtual machines. Right now I have v6 working great on the dom0 using a 6in4 provided by Hurricane Electric as I do not have native v6. However, I would like to distribute some of the /48 I am receiving to the domUs (/64 per machine would be ideal, but I am open to your suggestions). Static configuration on the domU side is fine. All I want to accomplish is getting the traffic to pass through the dom0 to the domU. To say the least, I'm still trying to wrap my head around all the virtual interfaces and bridges Xen creates. Yes, I have Googled around for this a bit and have not found anything great. I tried using two "vif-route6" bash scripts with no luck (possibly due to my ignorance with Xen networking). I am still stuck (mainly in how to configure the dom0). I would like to imagine this problem is relatively easy to solve and I look forward to your suggestions and help! Edited post to clarify my end goal: getting IPv6 to domU guests. I am completely open to suggestions but am hoping for something other than setting up a tunnel for every guest.

It requires me to be in sudoers in the first place. amarzaya@linux-debian-gnu:/$ sudo /usr/sbin/visudo We trust you have received the usual lecture from the local System Administrator.

  • The suggested way to handle pip(easy_install) with homebrew?

    - by Drake
    I know there are brew-gem and brew-pip but it is still really easy to get confused. Let's say my Mac OS X is 10.7.2. There are at least, as far as I know, 3 locations for Python modules (assume 2.7): /System/Library/Frameworks/Python.framework/Versions/2.7/ /Library/Python/2.7/site-packages /usr/local/lib/python2.7/site-packages/ (controlled within homebrew) For some Python modules, pip install them into 2, the so-called local/customized Python module location, and everything looks and works great. Ex, readline by *easy_install* (ipython suggested me to install readline by *easy_install* instead of pip) For some, it would try to install some miscellaneous files (ex, man, doc, ...) into system-wide location, which requires sudo! Ex, ipython insisted on installing man and doc into /System/Library/Frameworks/Python.framework/Versions/2.7/share/, which violates permission issue and all I can do is to use sudo. For some Python modules installed by brew, they are symbolic linked to /usr/local/lib/python2.7/site-packages/. Everything seems great except that you have to remember to add this location into PYTHONPATH. I am wondering any suggested and uniform way to handle those mass, or any explanation to make those stuff crystal clear.

  • Nginx load balancing and maintaining URLs

    - by Steve Klabnik
    I'm trying to use nginx as a load balancer, and it's working great. One problem, though. The load balancing box is at 123.123.123.123, and the backend box is 456.456.456.456. So I have this config: upstream backend { server 456.456.456.456; } server { listen 80; server_name 123.123.123.123; access_log off; error_log off; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://backend; } } This works great. I hit 123.123.123.123 in my browser, and the page comes up. But now the URL in the browser says http://456.456.456.456. Do I need to use a rewrite rule or something to keep the url correct? I don't want it to be different when going to different backed servers. None of the tutorials I've read have mentioned anything about this.

  • PHP on several servers with session-sharing

    - by Etu
    there's certanly other threads about this, but I have one more question. We are about to scale the website at work to have more than one server. And we need to share the sessions between the servers. We have been looking into different solutions, one in memcached and use Memcached as sessionhandler in PHP. That will probably work. And the idea would be to run memcached on every machine and let all webservers access all other servers memcached servers, and then we have shared sessions between the machines, yay. (we have no resources to setup with sticky-sessions yet, that's a later project. we need this running, and we need this running now. and we will loadbalance with DNS for a starter) But then... If I want to take one server down, say, for maintenance, or a server crashes, or whatever reason. I don't want the users to just loose their sessions and have to start from the beginning... That's why we need some kind of replication, which Memcached does not support. Then I found http://repcached.lab.klab.org/ -- which has multi-master replication of memcached, which is great, and is what I want. But does it work with 2 machines? Say 3, 5, 10? For future scaling. I also looked into redishttp://redis.io/ -- which also seems great, but is a bit more "shaky" with the php-session-handler support, and no multi-master-replication. The thing is that I like to use memcached, but I want to be able to power down one of two boxes without loosing half of the sessions. Any suggestions?

  • How to do grap data between two file in Linux?

    - by user28167
    I have two .rtf file.... The first one have this content: Apple, Orange, Banana, Noodle, Chip The Second File is something like this: Apple I love eat Apple. Banana I hate Banana. Zoo I want to go Zoo. Noodle Noodle can be a very very very very very very very very very very very long, but still is one line. Chip Don't eat so many chip. Orange Orange is great, not Apple plx. Noodle Water Drinking water is boring. The first file is a "key" of second file. In the second file, the first word is the key of each line. Each key and sentence in second file ONLY have one line. The Second File have many lines with key, but not all the key is shown on file1, but file1's key MUST in the second file. How can I get the result like this: (Need to sort by the key from File1) Apple, Apple I love eat Apple. Orange, Orange is great, not Apple plx. Banana, I hate Banana. Noodle, can be a very very very very very very very very very very very long, but still is one sentence. Chip, Don't eat so many chip.

  • In Windows 7, why won't my display stay off despite the power settings saying it should?

    - by Jer
    I'm completely stumped by this. My simple use case is that when I'm in bed, I use a cordless mouse to browse the web, watch videos, etc. - the monitor is across the room. When I'm going to sleep, I want to shut the monitor off. I also want to be able to turn it back on in the morning. I just want to turn the monitor off and on using only the mouse. I thought of creating a power setting that turned the monitor off asap (the shortest amount of time is one minute; that's fine). I have one that does this. It worked great for almost a year on my old XP machine, and for about four months on my new Windows 7 laptop (which I essentially use as a desktop). All of a sudden a couple weeks ago, it just stopped working - my monitor won't turn off on its own anymore. Here are the settings: I tried other options. Based on the advice here I tried nircmd. This seemed great. I created a shortcut with the command line: "C:\Program Files\nircmd\nircmd.exe" cmdwait 1000 monitor off I click this, and in one second the monitor goes off. However about five seconds later it turns back on, and I've been extra careful to make sure the mouse isn't moving. I have no idea what's going on. Based on both of these things, my only guess is that something could be running in the background which somehow makes the computer think it's in use. I've tried killing as many programs as possible but I still get the same behavior. Any advice? I'm mainly curious about how to debug, but am open to other suggestions about turning the monitor off and on with just the mouse as well.

  • Howto get exit code of a script started in screen session

    - by Bettina
    Hi folks, I am currently creating a backup script which uses screen to start a backup job with rsync inside a screen session. The backup jobs are started as follows. screen -dmS backup /usr/bin/rsync ... As soon as the rsync job is finished, the screen session is terminated automatically. To make sure, that the backup was successful, I would like to check the exit code of the rsync job but unfortunately I really don't know how to get the exit code after the screen was terminated. Does someone have a good idea how to automatically check, if the rsync job was successful or not? Would be great if someone does. I already thought about using a temp file but like this: screen -dmS myScreen "rsync -av ... ; echo $? /tmp/myExitCode" but this unfortunately does not work. Then I thought about using stderr like in the example below: screen -dmS myScreen "rsync -av ... 2 /tmp/rsync-sterr None of my ideas worked out so far, since stderr is not written when I use the command above. :-( ? Would be great if someone has a good idea or even a solution. Cheers, Bettina
