  • ubuntu: Installed php-mcrypt but it doesn't show up in phpinfo()

    - by jules
    A web app I'm trying to install on my ubuntu 10.04 LTS requires mcrypt, and is generating this error: Fatal error: Call to undefined function mcrypt_module_open(). I know this is the same question as this one: Installed php-mcrypt but it doesn't show up in phpinfo(), but I tried several things, none of which worked, and have additional questions. I would comment on the original thread but don't have enough reputation to do so; forgive me for the duplicate question. My versions of php and mcrypt are (both installed via apt-get): php: 5.3.2-1ubuntu4.10 mcrypt: 5.3.2-0ubuntu Doing a php -m shows that the mcrypt module is installed. I installed mcrypt and php5-mcrypt via apt-get. Also, I'm using nginx as my web server. I have tried reinstalling mcrypt and restarting nginx, but still can't get mcrypt to show up on phpinfo() and calls to mcrypt are still broken. Here is some more info: $ php -i | grep "mcrypt" /etc/php5/cli/conf.d/mcrypt.ini, mcrypt mcrypt support => enabled mcrypt.algorithms_dir => no value => no value mcrypt.modes_dir => no value => no value I also checked that mcrypt is on in /etc/php5/cli/conf.d/mcrypt.ini and /etc/php5/cgi/conf.d/mcrypt.ini. Lastly, I'm using fastCGI with nginx. I googled around and saw suggestions to restart php5-fpm. I couldn't find php5-fpm in apt-get, I'm not sure if I still need php5-fpm since I already have fastCGI. Is there anything else I'm missing?

  • How do you monitor SSD wear in Windows when the drives are presented as 'generic' devices?

    - by MikeyB
    Under Linux, we can monitor SSD wear fairly easily with smartmontools whether the drive is presented as a normal block device or a generic device (which happens when the drive has been hardware RAIDed by certain controllers such as the one on the IBM HS22). How can we do the equivalent under Windows? Does anyone actually use smartmontools? Or are there other packages out there? The problem is that SCSI Generic devices just don't show up in Windows. If the drives aren't RAIDed we can see them fine. How I'd do it in Linux: sles11-live:~ # lsscsi -g [1:0:0:0] disk SMART USB-IBM 8989 /dev/sda /dev/sg0 [2:0:0:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg1 [2:0:1:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg2 [2:1:8:0] disk LSILOGIC Logical Volume 3000 /dev/sdb /dev/sg3 sles11-live:~ # smartctl -l ssd /dev/sg1 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 26~ Percentage Used Endurance Indicator |_ ~ normalized value sles11-live:~ # smartctl -l ssd /dev/sg2 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 3~ Percentage Used Endurance Indicator |_ ~ normalized value

  • Bash script to run a clamscan on Ubuntu- how to use return values properly?

    - by Marius
    I'm trying to put together a simple script that will scan my home directory with clamscan and give me a warning if any viruses were found. What I have so far is: #! /usr/bin/env bash clamscan -l ~/.ClamScan/$(date +"%a%b%d") -ir /home RETVAL=$? [ $RETVAL -eq 0 ] && notify-send 'clamscan finished. No viruses found' [ $RETVAL -eq 1 ] && notify-send 'clamscan found a virus' && touch ~/Desktop/VirusFound [ $RETVAL -eq 2 ] && notify-send 'clamscan encountered errors. Check the logs' && touch ~/Desktop/ClamscanError find ~/.ClamScan/* -mtime +7 -exec rm {} \; However, I'm unsure about a couple of things: I'm always wary of using rm- as far as I can tell, the find command I've got should be deleting any log files that are more than a week old. I'm also not entirely sure how the return value testing works- I've got a manual that briefly covers bash, which says that the meaning of $? is "match one character", and I'm not entirely sure how that grabs the return value. Should I be using -eq or = for testing the return value? From what I can tell -eq tests strings and = tests numerals, but I'm not sure what the type of the return value is.

  • How do I create a VBA macro that will copy data from an entry sheet, into a summary sheet by date

    - by Mukkman
    I'm trying to create a macro that will copy data from a data entry sheet into a summary sheet. The entry sheet is going to be cleared daily so I can't use a formula just to reference it. I want the user to be able to enter a date, run a macro, and have the macro copy the data from the entry sheet into the cells for the corresponding date on the summary sheet. I've looked around and found bits and pieces of how to do this but I can't put it all together. Update: Thanks to the information below I was able to find some additional data. I have a pretty crude macro that works if the user manually selects the correct cell. Now I just need to figure out how to automatically select the current cell relative to the current date. Sub Update_Deposits() ' ' Update_Deposits Macro ' Dim selectedDate As String Dim rangeFound As Range selectedDate = Sheets("Summary Sheet").Range("F3") Set rangeFound = Sheets("Deposits").Cells.Find(CDate(selectedDate)) Dim Total1 As Double Dim Total2 As Double Dim Total3 As Double Dim Total4 As Double Dim Total5 As Double Total1 = Sheets("Summary Sheet").Range("E6") Total2 = Sheets("Summary Sheet").Range("E7") Total3 = Sheets("Summary Sheet").Range("E8") Total4 = Sheets("Summary Sheet").Range("E9") Total5 = Sheets("Summary Sheet").Range("E10") If Not (rangeFound Is Nothing) Then rangeFound.Offset(0, 2) = Total1 rangeFound.Offset(0, 3) = Total2 rangeFound.Offset(0, 4) = Total3 rangeFound.Offset(0, 6) = Total4 rangeFound.Offset(0, 7) = Total5 End If ' End Sub This version will find the first value on the page and fill in values: Sub Update_Deposits() ' ' Update_Deposits Macro ' Dim selectedDate As String Dim rangeFound As Range selectedDate = Sheets("Summary Sheet").Range("F3") Set rangeFound = Sheets("Deposits").Cells.Find(CDate(selectedDate)) Dim Total1 As Double Dim Total2 As Double Dim Total3 As Double Dim Total4 As Double Dim Total5 As Double Total1 = Sheets("Summary Sheet").Range("E6") Total2 = Sheets("Summary Sheet").Range("E7") Total3 = Sheets("Summary Sheet").Range("E8") Total4 = Sheets("Summary Sheet").Range("E9") Total5 = Sheets("Summary Sheet").Range("E10") If Not (rangeFound Is Nothing) Then rangeFound.Offset(0, 2) = Total1 rangeFound.Offset(0, 3) = Total2 rangeFound.Offset(0, 4) = Total3 rangeFound.Offset(0, 6) = Total4 rangeFound.Offset(0, 7) = Total5 End If ' End Sub

  • How to let MSN or Yahoo Messenger set you to be Invisible or Offline when you are idle for an hour?

    - by Jian Lin
    The short question is: How do we let MSN or Yahoo Messenger set us to be Invisible or Offline when we are idle for half an hour or an hour? The reason is: if I am on 24 hours a day, some people see me as weird. Some people see my value as low, because I am always there. There are ways to set me to "Away" or "Busy" after 10 minutes, but there seems to be no way to set myself to invisible or offline after 1 hour. As I am a software developer, I am very used to turning the computer on 24 hours a day. (for example, for checking email for urgent fixes, and fix issue and push to web server). We don't turn off computer usually even when we sleep, because we may sometimes can't sleep yet and come check on the computer, or wake up in the morning and immediately need to check if everything is ok. But, my MSN and Yahoo Messenger is always on for 24 hours a day, and I found that some girls start to ask me why I am always there 24 hours a day (even though they see me as away or busy, their feeling is that I am always there). What's more, I found that since I am always there, my value actually drop in their eyes, because hard to get = high value, and always there = low value. Some people feel me as having nothing much to do, always in front of computer, or what is he doing in front of computer so much? Now since it is my job, and I need to read emails once in a while, I am in fact in front of the computer more than some other people. I am in front of the computer maybe 10 hours a day, far from 24 hours a day. Is there an easy and automatic solution to this?

  • 16TB Volumes and SNMP On Windows

    - by John K
    As volumes larger than 16TB became more common, it was recognized that the 32 bit value used to report disk size and usage within the standard "HOST-RESOURCES" MIB in SNMP was not large enough to report the proper disk size. Net-SNMP seems to have addressed this issue by simply manipulating the value of "AllocationUnits" to maintain a 32 bit value for disk utilization (since total disk size/usage is equal to the 32 bit space value times the allocation unit), to allow for the calculation of a volume larger than 8/16TB. Presuming you don't have any reporting interest in the allocation unit, this seems like a fine solution. https://bugzilla.redhat.com/show_bug.cgi?id=654384 Window's built in SNMP service, however, seems to continue to suffer from this error, simply reporting the modulo of the used/assigned disk space, resulting in inaccurate disk size reporting. Is there a way to enable Windows to correctly report disk usage for volumes over 16TB? We attempted to simply install Net-SNMP 5.5 x64 and disable Windows SNMP service entirely, however this unfortunately did not fix our issue. I've seen people in the Cacti community mention simply scripting out a solution. Unfortunately, we're using Observium for quick and basic systems monitoring. If the issue can't be correct on the Window's side, can Observium be made to report custom MIBs?

  • Incorrect deployment of WSGI app to AWS using Elastic Beanstalk

    - by Dzmitry Zhaleznichenka
    cross-link to AWS forums I have developed a simple Python web service using WSGI and would like to deploy it to AWS cloud using Elastic Beanstalk. My problem is I cannot make all the options I specify in Elastic Beanstalk configuration to be correctly configured in the cloud. For deployment, I use Elastic Beanstalk CLI utility. I have run eb init command and set up the required parameters. After this, a directory named .elasticbeanstalk was created in my source tree. It has two config files that are used for deployment, namely config and optionsettings. The latter one among the other options contains the WSGI configuration that has to update /etc/httpd/conf.d/wsgi.conf at the instances. After some of my adjustments the file has the following settings: [aws:elasticbeanstalk:application:environment] DJANGO_SETTINGS_MODULE = PARAM1 = PARAM2 = PARAM4 = PARAM3 = PARAM5 = [aws:elasticbeanstalk:container:python] WSGIPath = handler.py NumProcesses = 2 StaticFiles = /static= NumThreads = 10 [aws:elasticbeanstalk:container:python:staticfiles] /static = static/ [aws:elasticbeanstalk:hostmanager] LogPublicationControl = false [aws:autoscaling:launchconfiguration] InstanceType = t1.micro EC2KeyName = zmicier-aws [aws:elasticbeanstalk:application] Application Healthcheck URL = [aws:autoscaling:asg] MaxSize = 10 MinSize = 1 Custom Availability Zones = [aws:elasticbeanstalk:monitoring] Automatically Terminate Unhealthy Instances = true [aws:elasticbeanstalk:sns:topics] Notification Endpoint = Notification Protocol = email It turns out that not all of these options are considered when I start the environment or update it. Thus, when I update NumThreads or NumProcesses, the respective parameters get changed in wsgi.conf as expected. But whatever I write to the WSGIPath and StaticFiles parameters, I'm not able to automatically change the respective values of wsgi.conf, they remain Alias /static /opt/python/current/app/ WSGIScriptAlias / /opt/python/current/app/application.py which drives me nuts. Moreover, when I deploy my application using git aws.push and having the following contents of .ebextensions/python.config file, neither of options I specify in it affects the deployment. option_settings: - namespace: aws:elasticbeanstalk:container:python option_name: WSGIPath value: mysite/wsgi.py - namespace: aws:elasticbeanstalk:container:python option_name: NumProcesses value: 5 - namespace: aws:elasticbeanstalk:container:python option_name: NumThreads value: 25 - namespace: aws:elasticbeanstalk:container:python:staticfiles option_name: /static/ value: app/static/ I wonder what I should do to force AWS use all the parameters I specify in the configuration, namely the WSGI Path and path to my static data.

  • PHP enable sqlite phpinfo states --without-sqlite

    - by Jahmic
    I've seen similar questions but none that address my situation adequately. I'm running Apache and PHP 5.3.6 on a amazon cloud server. phpinfo keeps stating that sqlite is disabled. At least that what it seems from the configure line: './configure' ... '--without-sqlite' In other parts of phpinfo() output: PDO PDO drivers mysql, sqlite PDO Driver for SQLite 3.x enabled SQLite Library 3.6.20 sqlite3 SQLite3 support enabled SQLite3 module version 0.7-dev SQLite Library 3.6.20 Directive Local Value Master Value sqlite3.extension_dir no value no value and at least one the following PHP commands fail: if (!extension_loaded('SQLite') OR !function_exists('sqlite_open')) Yum install states that both sqlite and pdo-lite are already installed. I've tried to enable sqlite by editing my local php.ini by adding: ; Enable sqlite3 extension module extension=sqlite3.so I've checked the main php.ini (/etc/php.ini) and there is nothing specific about disabling it. In fact, there is a sub-conig file loaded in php.d that also specifies this extension as well as another for the pdo-sqlite I'm running of things to look for or try. Any suggestions. How do I find where the PHP configure is stated? Thanks

  • How can I do a large file upload using Sinatra, haml, nginx, and passenger?

    - by mmr
    Hi all, I need to be able to allow a user to upload 30-60 mb files at a time. Right now, I'm solving the problem with a simple form post: %form{:action=>"/Upload",:method=>"post",:enctype=>"multipart/form-data"} - @theModelHash.each do |key,value| %br %input{:type=>"checkbox", :name=>"#{key}", :value=>1, :checked=>value} =key %br %input{:type=>"file",:name=>"file"} %input{:type=>"submit",:value=>"Upload"} This form allows the user to select processing options contained in theModelHash and upload a file for processing. Problem is, this method both freezes the user's UI and also requires that the entire form be reposted when the user presses the 'back' button. I've looked at SWFUpload, but have no idea how to integrate that into my relatively simple app. There's a page here about integrating it with Rails, but I'm using Sinatra, and am new enough to this whole web programming thing that I don't know how to modify those files to work with what I need to do. Is there a how-to to add large file uploads to my form there? Something relatively simple that just adds in a progress bar and doesn't repost? I feel like I'm having to triple the size of my application just to make this feature play nice, and that's bothering me a bit.

  • Excel 2007 pivot table does not aggregate properly

    - by Patrick
    I am using a an excel pivot table to summarize some data and just found a problem. The problem deals with how aggregate values are calculated. Let's say I have a table of data with three columns: Name, Date, Value. If I create a table where Name and then Date are used as Row Labels and Value is the aggregate value, ie Average. The pivot table will look something like this: +John .3450 5/14/2010 1.234 5/15/2010 3.450 5/16/2010 -3.25 What I think should be happening here is that the values for each date are averaged and then those values are averaged to come up with the value in the same row as the Name, John. But that is not what it does. It takes the average for each date, which it shows across from the date, but then instead of taking the average of those numbers, it actually uses the raw data and computes the average for all of John's values. It should show the average of the daily averages to correspond with the tree hierarchy, but instead just shows me the average for all of John's values. It essential will only aggregate at one level, but visually creates sub levels that it is not using. Does anyone know how to change this or understand by what logic this makes sense? Why would I create any sub groupings if I cannot compute aggregates on them?

  • How to create partition when growing raid5 with mdadm.

    - by hometoast
    I have 4 drives, 2x640GB, and 2x1TB drives. My array is made up of the four 640GB partitions and the beginning of each drive. I want to replace both 640GB with 1TB drives. I understand I need to 1) fail a disk 2) replace with new 3) partition 4) add disk to array My question is, when I create the new partition on the new 1TB drive, do I create a 1TB "Raid Auto Detect" partition? Or do I create another 640GB partition and grow it later? Or perhaps the same question could be worded: after I replace the drives how to I grow the 640GB raid partitions to fill the rest of the 1TB drive? fdisk info: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe3d0900f Device Boot Start End Blocks Id System /dev/sdb1 1 77825 625129281 fd Linux raid autodetect /dev/sdb2 77826 121601 351630720 83 Linux Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc0b23adf Device Boot Start End Blocks Id System /dev/sdc1 1 77825 625129281 fd Linux raid autodetect /dev/sdc2 77826 121601 351630720 83 Linux Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x582c8b94 Device Boot Start End Blocks Id System /dev/sdd1 1 77825 625129281 fd Linux raid autodetect Disk /dev/sde: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xbc33313a Device Boot Start End Blocks Id System /dev/sde1 1 77825 625129281 fd Linux raid autodetect Disk /dev/md0: 1920.4 GB, 1920396951552 bytes 2 heads, 4 sectors/track, 468846912 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000

  • So who decided VGA cables should be symetrical ? [closed]

    - by mgb
    < rant So who decided that VGA cables should be the same gender connector at both ends? I just spent an hour trying to fix a server that would apparently boot but wouldn't display any post messages - I needed to change some bios settings. The monitor gives me a helpful error message - "unable to display this resolution". Wondering how it can't show simple VGA res, I reset the bios, when that doesn't work I remove the BIOS battery. The system is in a rack with a keyboard and monitor mounted 6ft away - with the cable running through the normal waist thick rats nest of wiring of wiring. The monitor worked with another system, so it and the VGA cable are good, I brought in another monitor and tried that - still nothing. Eventually I ripped the rack apart to discover that the other end of the VGA connector I was trying to plug into the server was actually plugged into another server box ! And the second monitor I was testing was plugged into the first monitor. An error message like - "I'm actualy plugged into another monitor stupid" - would be useful. So would having a connector with a male end and a female end. < end rant - thank you

  • memory tuning with rails/unicorn running on ubuntu

    - by user970193
    I am running unicorn on Ubuntu 11, Rails 3.0, and Ruby 1.8.7. It is an 8 core ec2 box, and I am running 15 workers. CPU never seems to get pinned, and I seem to be handling requests pretty nicely. My question concerns memory usage, and what concerns I should have with what I am seeing. (if any) Here is the scenario: Under constant load (about 15 reqs/sec coming in from nginx), over the course of an hour, each server in the 3 server cluster loses about 100MB / hour. This is a linear slope for about 6 hours, then it appears to level out, but still maybe appear to lose about 10MB/hour. If I drop my page caches using the linux command echo 1 /proc/sys/vm/drop_caches, the available free memory shoots back up to what it was when I started the unicorns, and the memory loss pattern begins again over the hours. Before: total used free shared buffers cached Mem: 7130244 5005376 2124868 0 113628 422856 -/+ buffers/cache: 4468892 2661352 Swap: 33554428 0 33554428 After: total used free shared buffers cached Mem: 7130244 4467144 2663100 0 228 11172 -/+ buffers/cache: 4455744 2674500 Swap: 33554428 0 33554428 My Ruby code does use memoizations and I'm assuming Ruby/Rails/Unicorn is keeping its own caches... what I'm wondering is should I be worried about this behaviour? FWIW, my Unicorn config: worker_processes 15 listen "#{CAPISTRANO_ROOT}/shared/pids/unicorn_socket", :backlog = 1024 listen 8080, :tcp_nopush = true timeout 180 pid "#{CAPISTRANO_ROOT}/shared/pids/unicorn.pid" GC.respond_to?(:copy_on_write_friendly=) and GC.copy_on_write_friendly = true before_fork do |server, worker| STDERR.puts "XXXXXXXXXXXXXXXXXXX BEFORE FORK" print_gemfile_location defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect! defined?(Resque) and Resque.redis.client.disconnect old_pid = "#{CAPISTRANO_ROOT}/shared/pids/unicorn.pid.oldbin" if File.exists?(old_pid) && server.pid != old_pid begin Process.kill("QUIT", File.read(old_pid).to_i) rescue Errno::ENOENT, Errno::ESRCH # already killed end end File.open("#{CAPISTRANO_ROOT}/shared/pids/unicorn.pid.ok", "w"){|f| f.print($$.to_s)} end after_fork do |server, worker| defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection defined?(Resque) and Resque.redis.client.connect end Is there a need to experiment enforcing more stringent garbage collection using OobGC (http://unicorn.bogomips.org/Unicorn/OobGC.html)? Or is this just normal behaviour, and when/as the system needs more memory, it will empty the caches by itself, without me manually running that cache command? Basically, is this normal, expected behaviour? tia

  • Ruby net:LDAP returns "code = 53 message = Unwilling to perform" error

    Hi, I am getting this error "code = 53, message = Unwilling to perform" while I am traversing the eDirectory treebase = "ou=Users,o=MTC". My ruby script can read about 126 entries from eDirectory and then it stops and prints out this error. I do not have any clue of why this is happening. I am using the ruby net:LDAP library version 0.0.4. The following is an excerpt of the code. require 'rubygems' require 'net/ldap' ldap = Net::LDAP.new :host => "10.121.121.112", :port => 389, :auth => {:method => :simple, :username => "cn=abc,ou=Users,o=MTC", :password => "123" } filter = Net::LDAP::Filter.eq( "mail", "*mtc.ca.gov" ) treebase = "ou=Users,o=MTC" attrs = ["mail", "uid", "cn", "ou", "fullname"] i = 0 ldap.search( :base => treebase, :attributes => attrs, :filter => filter ) do |entry| puts "DN: #{entry.dn}" i += 1 entry.each do |attribute, values| puts " #{attribute}:" values.each do |value| puts " --->#{value}" end end end puts "Total #{i} entries found." p ldap.get_operation_result Here is the output and the error at the end. Thank you very much for your help. DN: cn=uvogle,ou=Users,o=MTC mail: --->[email protected] fullname: --->Ursula Vogler ou: --->Legislation and Public Affairs dn: --->cn=uvogle,ou=Users,o=MTC cn: --->uvogle Total 126 entries found.

  • Importing long numerical identifiers into Excel

    - by Niels Basjes
    I have some data in a database that uses ids that have the form of 16 digit numbers. In some situations i need to export the data in such a way that it can be manipulated in excel. So i export the data into a file and import it into excel. I've tried several file formats and I'm stuck. The problem I'm facing is that when reading a file into excel that has a cell that looks like a number then excel treats it as a number. The catch is that (as far as i can tell) all numerical values in excel are double precision floating point which have a precision of less than 16 digits. So my ids are changed: very often the last digit its changed to a 0. So far I've only been able to convince excel to keep the Id unchanged by breaking it myself: by adding a letter or symbol to the Id. This however means that in order to use the value again it must be "unbroken". Is there a way to create a file where i can specify that excel must treat the value as a text without changing the value? Or its there a way to let excel treat the value as a long (64bit integer)?

  • Changing open-files-limit in mysql 5.5

    - by davidv
    I'm having an issue with mysql 5.5 running on Ubuntu 12.04 with the open-files-limit parameter. I recently noticed some problems due to the 1024 limit, and actually the main system limit was set to 1024, so I modified /etc/security/limits.conf with the following: * soft nofile 32000 * hard nofile 32000 root soft nofile 32000 root hard nofile 32000 After that I check the ulimit value for root and even for mysql user, both returned the new value: 32000, so I assume the change has already been done. I also changed the value at the my.cnf file, setting open-files-limit to 24000, like this: open-files-limit = 24000 Now comes the odd part, when I restart the mysql service and check the open_files_limit variable, it returns that it's still set to 1024, so I'm having the same problems that before (obviously), I tried to use open-files-limit instead open_files_limit in the my.cnf config file, same result, BUT if I override the service command to start the service and start only using mysqld (no additional parameters), the service starts and when I check the parameter it returns 32000... I don't know where it's taking that value from, as it's not set at my.cnf and it's not being given through command line, at least, not for myself. Any ideas about why it's not working the change and how to solve it the normal way (launching it through service...)?

  • Apache caching with mod_headers mod_expires

    - by Aaron Moodie
    Hi, I'm working on homework for uni and was hoping someone could clarify something for me. I need to set up the following: Configure the response header "Cache-Control" to have a "max-age" value of 7 days since access for all image files Configure the response header "Cache-Control" to have a "max-age" value of 5 days since modification for all static HTML files. Configure the response header "Cache-Control" to have a value of "public" for all static HTML and image files. Configure the response header "Cache-Control" to have a value of "private" for all PHP files. My question is whether it is better to use a FilesMatch, or the mod_expires ExpiresByType to best achieve this? I've so far used the following: <FilesMatch "\.(gif|jpe?g|png)$"> ExpiresDefault "access plus 7 days" Header set Cache-Control "public" </FilesMatch> <FilesMatch "\.(html)$"> ExpiresDefault "modification plus 5 days" Header set Cache-Control "public" </FilesMatch> <FilesMatch "\.(php)$"> Header set Cache-Control "private" </FilesMatch> Thanks.

  • domain user disabling screensaver

    - by RASG
    I have the following situation: Due to security reasons the screensaver is activated after 10 minutes, and immediately locks the screen. There are GPOs preventing the user from changing the screensaver parameters and the background image. In order to bypass the background policy, some users are using bginfo The problem is that for some reason now the screensaver doesn't work anymore. The settings are still the same (10 minutes; locked to the user) and comparing snapshots of the registry before and after executing bginfo doesn't show any significant modification. Any hints? EDIT 1: Ok, i figured whats going on, but now i have another question. bginfo refreshes the user settings by reading HKEY_CURRENT_USER\Control Panel\Desktop, which has ScreenSaveActive. If the user set it to 0, disables the screensaver. Why isnt HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop, which sets ScreenSaveActive to 1, being enforced? or if it is being enforced, where is bginfo storing the value 0, and how can it bypass the policy? EDIT 2: I also discovered that after setting any value to HKEY_CURRENT_USER\Control Panel\Desktop\ScreenSaveActive, it can be deleted and the last value will remain active. For some reason HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop\ScreenSaveActive value is not being enforced to the user.

  • Implications of Multiple JobTracker nodes in a Hadoop cluster?

    - by Jim Dennis
    I get the impression that one can, potentially, have multiple JobTracker nodes configured to share the same set of MR (TaskTracker) nodes. I know that, conventionally, all the nodes in a Hadoop cluster should have the same set of configuration files (conventionally under /etc/hadoop/conf/ --- at least for the Cloudera Distribution of Hadoop (CDH). Can we define multiple Job Trackers in mapred-site.xml? Something like: <configuration> <property> <name>mapred.job.tracker</name> <value>jt01.mydomain.not:8021</value> </property> <property> <name>mapred.job.tracker</name> <value>jt02.mydomain.not:8021</value> </property> ... </configuration> Or is there some other allowed syntax for this? What are the implications of doing this. Does each JobTracker get information about the load on each TaskTracker node. In other words can the two JobTracker co-ordinated their scheduling across the TT nodes only based on the gossip information from the TTs or would they need to talk to one another? Is this documented anywhere?

  • Excel or Access: how to group several lines in a table and insert contents in columns? ("split column")

    - by Martin
    I have a table containing data of sold products (shown in the example on the left): Columns: Number of the order Product Name Attribute - specifies what is given in the following field "value", e. g. Customer Name or Product Variant Value - is the value of the Attribute Count - is the number of products of this variant sold in the order That means: Product B has 2 variants "c" and "d" Note that in Order 1 Product B was sold in Variant d only, because the letter "N" in field "D4" means "none". Note, that in OrdnerNo 3 Product B was sold only in Variant c, because for Variant d field "D9" is "N"!! This is confusing, but it is the structure of the original data (which I can not change). I need a way to convert the table on the left in a table like that on the right: one line for each product type Order Number Product Name Customer Name Count (number of products sold in this order) Variant - this is the problem, as it has to be filled with the So all rows with the same OrderNo and same product have to be grouped in to one, and I hope it is clear what I need. I tried to do it with Pivot Tables, but that fails, as the Count is always in each line, no matter if it has Value "N" or not and for the products without variants there is only one line for each order, however for products with variants there are several... So how could I create the right table with a VBA macro in MS Excel or maybe there is a trick in MS Access to do it directly or with an SQL query?

  • Connection timed out on Node.js app running under CentOS

    - by ss1271
    I followed this tutorial to create a simple node.js app on my CentOS: the node.js version is: $ node -v v0.10.28 Here's my app.js: // Include http module, var http = require("http"), // And url module, which is very helpful in parsing request parameters. url = require("url"); // show message at console console.log('Node.js app is running.'); // Create the server. http.createServer(function (request, response) { request.resume(); // Attach listener on end event. request.on("end", function () { // Parse the request for arguments and store them in _get variable. // This function parses the url from request and returns object representation. var _get = url.parse(request.url, true).query; // Write headers to the response. response.writeHead(200, { 'Content-Type': 'text/plain' }); // Send data and end response. response.end('Here is your data: ' + _get['data']); }); // Listen on the 8080 port. }).listen(8080); However, when I uploaded this app onto my remote server (assume the address is 123.456.78.9), I couldn't get access to it on my browser http://123.456.78.9:8080/?data=123 The browser returned Error code: ERR_CONNECTION_TIMED_OUT. I tried the same app.js code which runs fine on my local machine, is there anything I am missing? I tried to ping the server and its address was reachable. Thanks.
