  • complex cron job schedule

    - by Bob
    I know I can do this if I call a script to check, but I am curious if I can do this with just the cron. I need to run a job once/year on the first Saturday of July If that Saturday is July 4th, run it July 5th.

  • Nodejs for processing js and Nginx for handling everything else

    - by Kevin Parker
    I am having a nodejs running on port 8000 and nginx on port 80 on same server. I want Nginx to handle all the requests(image,css,etc) and forward js requests to nodejs server on port 8000. Is it possible to achieve this. i have configured nginx as reverse proxy but its forwarding every request to nodejs but i want nginx to process all except js. nginx/sites-enabled/default/ upstream nodejs { server localhost:8000; #nodejs } location / { proxy_pass http://192.168.2.21:8000; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; proxy_redirect off; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }

  • Design Patterns for Coordinating Change Event Listeners

    - by mkraken
    I've been working with the Observer pattern in JavaScript using various popular libraries for a number of years (YUI & jQuery). It's often that I need to observe a set of property value changes (e.g. respond only when 2 or more specific values change). Is there a elegant way to 'subscribe' the handler so that it is only called one time? Is there something I'm missing or doing wrong in my design?

  • SCCM not processing hardware Inventory

    - by Sreekumar
    We have some workstations that will not import hardware inventory into the SCCM 2007 database. What I've done: Client - verified workstation object is discovered in SCCM - installed ccm client on workstation - manually ran hardware inventory action - verifed Inventory report was sent successfully "Successfully sent report Destination:mp:MP_HinvEndpoint, ID ..... - watched file on client enter and exit temp folder on client. - successfully ran MP Spy to verify client communicates with server - uninstalled client, deleted ccm and ccmsetup folders and reinstalled. Server - no entries in MP_Hinv.log file that coorespond with time stamp of workstation - no entries in dataldr.log file that coorespond with time stamp of workstation Where are these files going? All T/S blogs expect entries in these logs. This is driving me crazy.

  • AD FS 2.0: Troubleshooting Event 364 and ThrowExceptionForHRInternal / NullReferenceException

    - by Shawn Cicoria
    Ran into a situation today where after AD FS federation server was installed, configured and up & running, “all of a sudden” it stopped working. Turned out that another installer that affected the default web site, also seemingly affected the AppPools associated to all Applications under the Default Web site. By changing the “Enable 32-bit Applications” either through IIS admin or via command line appcmd set apppool /apppool.name:MyAppPool /enable32BitAppOnWin64:false Back to normal…

  • No password is complex enough

    - by Blue Warrior NFB
    I have one user in my AD domain who seems to not be able to self-select a password. I may have another one, but they're on a different enough password-expiration schedule that I can't remember who it is right now. I can set a password via ADU&C just fine, but when he tries it via C-A-D he gets the "doesn't meet complexity" message. Figuring he was just doing something like 'pAssword32', I did some troubleshooting of my own and sure enough it doesn't want to take a password that way. He's one of our users that habitually uses a local account and then maps drives using his AD credentials so he doesn't get the your password will expire in 4 days, maybe you should change it prompts, so he's a frequent "my password expired, can you fix it" flyer. I don't want to keep having him set it via ADU&C over my shoulder every N days. I'm just fine setting temp passwords of 48 characters of keyboard-slamming and letting him change it something memorable. My environment is at the Windows 2008 R2 functional level, and I am using fine-grained password policies. In fact, I have two such policies: For normal users (minimum length, remembered passwords) For special utility accounts The password complexities I've tried match both policies for length and char-set selection. The permissions on the User object themselves look normal, SELF does indeed have the "Change Password" right. Is there some other place I should be looking for things that can affect this?

  • Would you attend this type of event..

  • Red Hat 5.4 slow processing

    - by yucefrizk
    I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt). I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller. any idea what could be the reason of this slowness?

  • Renicing complex multithreaded applications in Linux

    - by Vi
    Applications (especially big Java and C++ ones) often shows up as multiple lines in htop, each have separate PID and separate nice level. Also application can spawn a lot of child processes (like as in aptitude update), so I need to affect both parent one (to make new children have new priority) and child ones (to bring the effect immediately, not after the child terminates) How can I apply "renice" or "ionice" or "schedtool" to already launched big application?

  • Cloud services can't be reached from complex customer infrastructure

    - by Nock
    We have several services running on a cloud, they all are hosted on Windows Server 2012 R2, have public IP address and specific port. Some of our customers can't reach them because for "some reason" the ports are cut between a firewall between them and us. (some customers are using a shared internet connection in a multi tenant office and they can't change firewall communication) Well, you get it, we don't have the possibility to make all the firewall "allowing" the communication. My customers all runs Windows 7 at least. What is the best counter solution in such case, using Microsoft (Windows Server) technologies? The best would be some kind of tunneling communication or VPN, but the customer should also be able to access his/her enterprise resources. Bby the way, today we using IPSec using Windows Firewall to secure the communication, is IPSec tunneling a solution for us? Otherwise, is there a service in Windows to enable some kind of VPN between a client and a server but only for a given set of servers?

  • Bad HD video deinterlacing processing

    - by Guy Fawkes
    I have Ubuntu 12.04 32-bit with Unity. My system configuration is: CPU: Core 2 Quad Q6600 (2.4 GHz) RAM: 8192 Mb DDR2 Kingston Video: Palit GeForce GTX 260 216 SP, and my screen resolution is 1680x1050. I also have Window 7 Ulitimate installed, and I can see the same files in Media Player Classic without any horizontal lines. I've installed vdpau driver, NVIDIA drivers 304.51, and MPlayer 2 (within SMPlayer). I've disabled "Sync to VBlank" option in CCSM (because in other way, by default, MPlayer process use about 50-60 percents of my processor load), tried to swich between different deinterlace options in SMPlayer, used "-vc ffh264vdpau,ffmpeg12vdpau" (without quotes) parameters for MPlayer, switched to "Ubuntu 2D", but, finally, have no results. Any suggestions? How must I to set up MPlayer?

  • Prevent Linux from processing incoming ICMP Host unreachable packets

    - by bbc
    I have a test setup with one host on a network (10.1.0.0/16) talking via TCP to another one on another network (10.2.0.0/16) and a gateway in the middle. Sometimes, the TCP connection is lost and while scanning the trace (pcap), I looks like it's because of just one ICMP Host unreachable message sent by the gateway to 10.1.0.1 at some point. 10.1.0.1 then sends a TCP RST to 10.2.0.1. In my opinion, the gateway (pfSense) is broken or not configured correctly but anyway, for testing purposes, I'd like to block this kind of ICMP on the host (10.1.0.1) before it has an influence on my TCP connection (or does it? I'm not even sure). I've tried iptables: iptables -I INPUT -i eth0 -p icmp --icmp-type host-unreachable -j DROP but while it does a good job at preventing userpace applications like ping from receiving these ICMP messages, my TCP connection still comes to an end when the alleged "killer ICMP packet" is sent by the gateway. Am I right about how it is processed? If yes, then what can I do to achieve my goal?

  • Freelance for moderately complex admin support

    - by ongraphs
    Mailing lists and question/answers works great for problems that are independently encountered by several people. But sometimes we (as in experienced amateurs) run into problems that aren't so common, nobody has blogged about it and experts advice not readily available. For IT-admin related stuff can someone please recommend how can amateurs pay experts and get hands on advice. The kinds of problems I am talking about are like setting up nxserver or openvpn on freeBSD box. The install/config is not so simple, the documentation not easy for non-it professionals. Therefore getting step by step advice would be quite helpful. Thanks sandeep

  • Event Handlers and Automatic Postback in ASP.NET 3.5 Web Controls

    In one of last week s tutorials Creating Database-Driven ASP.NET 3.5 Input and List Web Controls you learned how to create a dynamic input web control that instead of setting values statically stored its list and values directly from the MS SQL server 2 8 database. This tutorial is a sequel to that article. It deals mostly with the server side coding aspect of dynamic web controls. It is recommended that you read the earlier tutorial first as the Visual Web Developer Project in that tutorial will be used extensively in this article....

  • Software that can identify and remove foreground objects from image

    - by Antonio2011a
    I am interested in removing extraneous objects from an image. More specifically the situation is that there is a series of images of a particular background. In each image there are objects in the foreground, however these objects differ across the series of images in terms of their location. Note that some objects always exists in the foreground. The background is static. An example might be a busy tourist spot and you want to remove the people or tourist buses from the image. I'd like the software to take the series of images and as much as possible reconstruct the background. Is there software available that has this capability? If so what are the steps necessary to use that functionality? Similarly if anyone knows a lot about image processing, are there any image processing algorithms that could handle this? Thanks.

  • Complex (?) Unix Text Replace Command

    - by Matrym
    What's the command line equivalent of: For every file that contains "AAA" within its contents, find "BBB" and replace it with "CCC" Thus, the command would match and replace BBB in a file: <html> <head></head> <body> AAA Hello world! BBB </body> </html> But Not in a file: <html> <head></head> <body> Don't match me! BBB </body> </html> Thanks in advance!

  • Complex nagios command

    - by gonvaled
    I have defined the following command for one of my service checks: define command{ command_name mycommand command_line $USER1$/check_by_ssh -p $ARG1$ -l nagios -i /etc/nagios2/keys/key1 -H $HOSTADDRESS$ -v -C 'source $USER10$ ; command.py -a get --alert-name $ARG2$ -q' } The problem is that it seems that nagios is parsing the command with the semicolon, and producing garbage which can not be executed. I have tried also putting a backslash \;, to no avail. If I run the command directly on the shell, it works. Which means that this is not a problem with check_by_ssh, but a problem on the parsing of the nagios configuration file. How can I debug this? Is there a way to get a listing of all the commands that nagios has parsed when reading the configuration files?
