• How to manage iowait over cifs?

  - by Silvia

  For backup purposes we have Cifs file Server running that contains encrypted containers for backing up the more sensitive data. The container is mounted with cryptsetup and loop as a local filesystem and the rsync is used for backups. Because the Cifs server is not the fastest machine ever built, running the rsync process results in an iowait on the servers running the backup which in turn drives Nagios into an email frenzy. The question is, how do reduce the iowait on the server? Configuring Nagios to not report seems more like a workaround then a solution. Stretching the backups over different time intervals is already done with little effect and spending money is also not an option because apparently, we are talking about a "non-critical system".

• Is there a rule of thumb for RAM upgrades?

  - by Retrosaur

  I'm having a hard time figuring out whether or not a certain laptop/computer's RAM can be upgraded or not. Is there a rule of thumb that determines how much max RAM one could add to a system without looking it up via external websites? A little bit of a background information: I work in computer sales at a computer electronics store, so it is virtually impossible for me to install any sort of software that would detect computer specs, and I get a lot of customers who wonder what laptop/desktop RAM upgrades usually are. Is there a certain rule that adding more RAM entails? Does it make a difference if it's a 32-bit or 64-bit machine? OS?

• Finding throuput of CPU and Hardrive on Solaris

  - by Jim

  How do i find the throughput of a CPU and the Hardisk on an open solaris machine. Using MPstat or iostat. I'm having a hard time identifying the throughput if it is given at all in the commands output. Eg. in mpstat there is very little explanation as to what the columns mean http://docs.sun.com/app/docs/doc/816-5166/mpstat-1m?l=en&a=view&q=syscl+mpstat I've been using the syscl column divided by time interval to find the throughput but to be honest i have no idea what a system call truelly is. I'm trying to to analyze a hardrive and CPU while writing a file to the hardisk and when at rest Thanks in advance. Jim

• How to enable extended logging for classic asp on IIS7 on Windows 2008 R2

  - by Neil Trodden

  I had to deploy an application that was not written by me onto the above configuration. It is a rather bizarre hybrid of asp.net and classic asp and it's the classic asp that is proving troublesome. The client is having problems with 500 Internal Server Errors appearing and I can see some of these in the logs but I only get the error code and the page name but little else. What I would like to see is the actual error message to at least give me an idea what is going on (or not going on, depending on your point of view) I don't want to display errors in the browser as I don't know the code well enough and this could (for all I know) display some crazy code where the db password is hard-coded into the site.

• MSDeploy - possible to call setAcl on multiple destinations in one go?

  - by growse

  I'm building a nice little continuous integration environment for our development team, based on TeamCity. It's working rather nicely, as it can build a mix of .NET and PHP projects, and push them to our internal and external platforms. I'm primarily using MsDeploy to push everything to the internal platform, as that's all IIS based. However, there's a number of builds where I need to set directory permissions on the destination directory. I can use the setAcl operator just fine, but that only seems to take a single destination as an argument. Therefore, if I need to alter the permissions on 5 destination directories, I need to call MsDeploy 5 times, which seems a lot of overhead. Is there a sensible way around this? Reading the documentation, I don't think MsDeploy takes more than a single argument for the setAcl operator, but could be wrong. Is there a better way for a build server to set multiple directory permissions in one go?

• Installing gitlab on Debian 6.0.5

  I am using following directions in an attempt to install gitlab on Debian 6.0.5 https://github.com/gitlabhq/gitlabhq/blob/stable/doc/installation.md I am getting an error when i'm running following command sudo -u gitlab bundle exec rake gitlab:app:setup RAILS_ENV=production WARNING: #<ArgumentError: Illformed requirement ["#<Syck::DefaultKey:0x00000004b52198> 1.1.4"]> # -*- encoding: utf-8 -*- Gem::Specification.new do |s| s.name = %q{carrierwave} s.version = "0.6.2" s.required_rubygems_version = Gem::Requirement.new(">= 0") if s.respond_to? :required_rubygems_version= s.authors = ["Jonas Nicklas"] ....more error.... s.add_dependency(%q<mini_magick>, [">= 0"]) s.add_dependency(%q<rmagick>, [">= 0"]) end end WARNING: Invalid .gemspec format in '/usr/local/lib/ruby/gems/1.9.1/specifications/carrierwave-0.6.2.gemspec' Could not locate Gemfile Some pointers to what could cause this would be much appreciated, i have only little experience with RoR and it seems to be related to that.

• Empty /var/log after running cron bash script

  - by Ortix92

  I wrote a little bash script and all of a sudden my /var/log folder is completely empty except for the log I created for the bash script. This is the script I'm running every hour with cron: #!/bin/bash STL_DIR=/path/to/some/folder/i/hid LOGFILE=/var/log/stl_upload.log now=`date` echo "----------Start of Transmission----------" 2>&1 | tee -a $LOGFILE echo "Starting transfer at $now" 2>&1 | tee -a $LOGFILE rsync -av -e ssh $STL_DIR [email protected]:/users/path/folder 2>&1 | tee -a $LOGFILE echo "----------End of transmission----------" 2>&1 | tee -a $LOGFILE printf "\n" 2>&1 | tee -a $LOGFILE I want to be clear that I'm not 100% certain this is related to the empty logs folder. So if anyone could give me a pointer as to what could be going on about the reason why my log folder is empty, that'd be great.

• How to fix White Screen of Death after updating iTunes?

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

• How to improve long text readability in Chrome?

  - by amiregelz

  I need to start reading The TCP/IP Guide. I have to admit that compared to other informative guides/tutorials/articles out there, this guide isn't so cluttered. However, I still find it a little bit hard to read, especially when reading for several hours. I don't know if it's the font, the contrast or the spacing, but this is why I've always preferred learning from books rather than from the internet. What can I do to make this guide more readable? I am reading it on Google Chrome.

• Any "Magic Tricks" For Getting Data Back After Windows 7 Install

  - by user163757

  My old man installed Windows 7 without making a proper backup, and now realizes he left behind some important data. He did a true "clean install", so there is no Windows.old folder in the root directory. However, I believe the format performed on the hard drive was only a quick format, so I am hoping there is some chance at data recovery. I took his hard drive out, and have spent a majority of the weekend researching data recovery options. I paid $70 for the GetDataBack software, but have had little success with it. I can see all of the files I want to restore, however they appear corrupt when I try to open them. With that all being said, does anyone know of a viable way to recover some of this data, or is it a lost cause all together?

• RSync to WebDAV mounted volume very slow

  - by AlexC

  I have a mounted WebDAV store, which I am playing around with to try and put together my own pseudo-DropBox set up. However, it seems very slow to upload larger files (my bandwidth graph goes ok for a little bit, then just stops dead for long periods of time). Has anyone tried this? I'm wondering if the way it gets mounted makes rsync think it's a local drive or something and so may be chattier than it would be if it knew it was a mounted network drive? (I'm new to rsync so may be all wrong here!) I'm syncing using rsync -rv /source/directory/ /mounted/webdav/directory/ This is running using MacOS 10.6, and WebDAV is mounted using the native mounting mechanism.

• Photo Management Software for OS X That Supports Multiple Library Locations

  - by Lance Rushing

  I'm looking at the possibility of changing our photo management software. Thinking about Aperture or Lightroom. And want to know if either supports: Having folders/libraries on separate harddrives/Volumes. Tolerates having network folders occasionally connected Snappy interface A solid enough piece of software as not to crash or behave weirdly. [ so the wife doesn't get stuck and have to call me ;) ] Background The wife is photographer and I'm the computer programmer. Our current setup is Picasa, with a "Recent/Working" folder on the local iMac harddrive, and "Archive" folders on NFS mounted Linux Server, Raid 5, for redundant and extra storage capacity. (the Linux server also syncs with Amazon's EC2) Picasa is doing OK, but I get annoyed when it doesn't do behave properly. Usually around issues when the Linux disk isn't mounted. And overall, I wish Picasa seemed a little more polished and snappier. Thanks, Lance

• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• CRL checking problem windows 2003

  - by Tim Mahy

  Hi all, we have CRL that is valid for 24 hours and has a next update in 12 hours. The CRL is valid from 12:12 AM to 12:12 AM and from 12:12 PM to 12:12 PM. In the logs of the CRL hosting webserver we see that one of our servers not always fetches the CRL at night, in most cases the server that missed the CRL IIS servers 403.16 on 12:13 PM. Is our following theory good: when a windows server misses fetching the CRL on it's nextUpdate but the current CRL is still valid, the fetching is not retried? This leads to a situation that when the CRL expires there is no overlap and gives a little time of 403.16 situations in IIS since the CRL is not thrusted and so all certificates are marked als unsafe? greetings, Tim

• [xUbuntu] Move a window back into the visible area?

  - by Johan

  Hi I have this annoying little problem on my laptop that sometimes after I have used a external monitor (with higher resolution) some applications place them self outside the visible area of my desktop. So the question is how do I move them back into the visible area? (please note that no part of the window is visible so I can't use the mouse) Is there some app that can give me focus to move a application to the mouse pointer or something like that? Please note that I'm running xUbuntu (xfce) on this laptop. Thanks Johan

• Direct DB to Web Server connection

  - by Joel Coel

  I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

• virtual machines

  - by André Alçada Padez

  well, i hope this doesn't get categorized as a boating question, but it really is related to programming. I have windows XP, and i am going to have to have a VM running: Windows 7 Visual Studio 2008 Sql Server 2008 IIS 7 (8 in a little while) Wamp Photoshop CS5 etc... so i was wondering what should i use to be easier to install and configure, and best performance: Virtual Box or Microsoft's Virtual Machine? Thank you Well i tried Virtual Box, it's always crashing for some reason. I think i'm going to try Virtual PC, just to stick to an all Microsoft Solution.

• Running Multiple Instances of Firefox

  - by Aaron Bush

  I am running SysInternal's Desktops 1.02 and FireFox 3.6.2. I have noticed that while I can have IE8 open in multiple Virtual Desktops, you can not Firefox. If you try you get the error message: Firefox is already running, but is not responding. To open a new window, you must close the existing FireFox process, or restart your system. I did a little digging around to work around this and came up with creating a second profile via the Firefox profile manager (accessed by starting FF with the "-p" switch). This unfortunately created a new problem which is my add-ons (of which I use many) do not stay synchronized between profiles. Is there a better approach here?

• Is there a usable HTML web gallery template for Lightroom 2?

  - by Johannes Rössel

  The built-in HTML gallery unfortunately generates invalid HTML markup so its looks are likely more coincidence than proper design. That aside its JavaScript usage prevents using the middle mouse button to open an image in a new tab. A look at the few free HTML gallery templates out there shows me that there seems to be little interest in building an actual HTML gallery which doesn't use JavaScript. Most of them are using JS to build fancy animations or in-page popup boxes containing the image. This may be nice for some people but at least one person who looks at my images is on dial-up and quickly opening all images in individual tabs to let them load and then close the connection is very nice to have there. Anyone seen such a gallery template; i. e. simple, plain HTML without JS? My HTML/CSS skills aren't that good that I can develop such a thing on my own, unfortunately.

• Can I bridge two wired networks with a Netgear WG602 (v4)

  - by Mr. Flibble

  I have two networks and I want to join them. Only one has a router. The other is currently just a bunch of computers joined via a switch. So it looks a little like this: 1. Router + comp1 + comp2 + wireless ap 2. comp3 + comp4 + Netgear WG602 Is it possible to use the WG602 to connect to the WIFI of the main network (the one with the router) and connect via wire to the 2nd network - therefore allowing the computers on network 2 to use the router on network 1?

• Enable Server Status using Plesk 11

  - by Lars Ebert

  I am trying to get apaches server status to work with Plesk 11. But running sudo /usr/sbin/apache2ctl fullstatus results in: Forbidden You don't have permission to access /server-status on this server. __________________________________________________________________ Apache Server at localhost Port 80 'www-browser -dump http://localhost:80/server-status' failed. Maybe you need to install a package providing www-browser or you need to adjust the APACHE_LYNX variable in /etc/apache2/envvars How can I enable server status? So far I have tried to insert <Location /server-status> SetHandler server-status Order Deny,Allow Deny from all Allow from localhost </Location> into the httpd.conf, but I am not sure if it is active. I also tried adding it to /var/www/vhosts/somedomain/conf/vhost.conf but I do not know which domain I have to add this to, as fullstatus seems to query localhost directly. I guess I am a little confused by the use of vhost configuration in Plesk.

• How to change the placement of the left border of tables in Word

  - by mkva

  Hallo everybody I have the following problem: in MS Word, the left-side (and also the right-side) border is not aligned with the rest of the text on a page. It's actually the text in the first column of a table that is aligned with the text outside the table. And the table border is a little bit to the left. I find this layout quite a bit annoying, as I don't want to have any elements on a page outside the range that is used by normal text. Now my question: is it possible to have tables in Word such that the border lines align with the text outside the table? Thanks, Markus

• How to configure citrix presentation server 4.5 login config

  - by Cory

  Hello, I am a little confused as to something my Citrix Server has been doing. When I login to the web login, (username, password, domain); everything logs in ok and I see all the available application. The problem that I was trying to fix is that when I try to start an application, it asks me to login again to the server that is hosting the citrix server. So, is there anyway to have the initial login credentials pass-through to the server login or skip the server login completely? Side note - I do have pass-through authentication enabled on both my internal and external Citrix site. Thanks for the help! Cory
