• Vagrant is creating files and folders in my project

  - by SERPRO

  Recently I updated Vagrant (v 1.6.3) and I noticed that in the folder of my project there are some new folders and files like: d20140610-11944-1j6n1cz/ d20140610-15421-1pkz3t8/ vagrant20140610-11944-p76ezc vagrant20140610-11944-p76ezc2 vagrant20140610-11944-yt3bhz vagrant20140610-11944-yt3bhz1 vagrant20140610-15421-mfqrig vagrant20140610-15421-mfqrig1 vagrant20140610-15421-y3r71a vagrant20140610-15421-y3r71a2 vagrant20140610-15421-y3r71a2.lock most of the files are empty, others have text like this: source "https://rubygems.org" source "http://gems.hashicorp.com" gem "vagrant", "= 1.6.3" group :plugins do gem "vagrant-login", nil, {} gem "vagrant-share", nil, {} end The directories have a file named config with this this info: BUNDLE_PATH: "/home/user/.vagrant.d/gems" Is this some kind of debug option? how can I disable it?

• Applying flattened css to xhtml

  - by rahul

  Hi, I try to apply flattened css to xhtml (which get from websites). I am using css4j-0.12.1.jar (from http://www.informatica.info/projects/css/) to process the url html content. For a few urls the code seems to be hang. Even no exception is thrown. For a particular stylableelement or style code doesnot return any value and hangs. For a few websites code hang in, CSSStyleDeclaration.getPropertyValue(style); and for a few websites code hang in, CSSStylableElement.getComputedStyle(); I am using the latest jar. Could you please update me, is there any known issue or fix for this. I am not sure where to post this issue. If anyone knows please update me. Thanks in Advance.

• Force running a program as non-administrator in Vista

  - by Peter Taylor

  I've just installed, on Vista 32-bit, a program which in my opinion shouldn't require administrator rights. It's not installed in a system directory, and its purpose shouldn't obviously require any special privileges. However, the .exe has a UAC shield on it, and it asks me to elevate privileges immediately upon execution. I'm prepared to risk it doing nasty things with the privileges of my user account, but not prepared to risk elevating it. Is there anything I can do short of setting up a virtual machine for it (or downloading the source and compiling it myself)? (FWIW, the program in question is Pencil - pencil.evolus.vn/en-US/Downloads/Application.aspx - but I'm more interested in general answers than app-specific ones).

• Client-based program to track response time for online webservice

  - by Søren Haagerup

  I am helping a customer with general IT support, and they have a problem with a hosted web-based system being slow. The provider of the system blames the client's computer, and the client calls me for help. I blame the provider, but it is hard to get them to do something about it without rock-solid evidence. And every time the provider comes around for a TeamViewer session, everything of course runs smoothly. Does there exist a client program or browser plugin that tracks statistics about response time for specific web services?

• Transfer some information from 1 workbook to another plus 1

  - by Cheryl

  I have 1 workbook with 4 sheets. Some of the information is auto entered from 1 sheet to another. I do not save when closing out. It is entered, printed and deleted. I need to get some of the information off those sheets to a seperate workbook that I save. Example: worksheet 1 info Name dob reason etc I am wondering if I can transfer that information to another sheet to be entered on row one and then the next one on row 2 and so on. Since I do not save the first workbook, will this work?

• Hibernate speed, and hard drive temperature

  - by cometbill

  My computer is taking in the region of 4 minutes or so, to hibernate 4GB of RAM. Also, resting my hand on the top of it is rather hot to the touch, so I ran CrystalDisk Info and that is reporting a temperature of 49 degrees C. I It's a Western Digital 5400 rpm drive, I've had it in the laptop since I bought it for most of the 2.75 years I've had it. Power on Count is 1219 Power on Hours is 3940 hours Boot up time is quicker than resuming from hibernate, too. Is there anything I can / should check ? Advice is greatly appreciated.

• Can't access files on external drive after reformatting Macbook Pro

  - by Peter Wells

  I recently had to reformat my Macbook Pro, and imported my account and settings from Time Machine via the Migration Assistant. Everything on the Mac itself is fine, but now I don't have permission to access almost everything on my external drive. A number of folders have the little red 'no access' sign on them and I can't rename or move anything. Looking at the info for these files, it appears that access rights were attached only to my old user account. Is there some way to reassign these files and folders to my new user account? Thanks.

• How do I force a specific MTU for only certain TCP ports?

  - by Dave S.

  Background I have a set of embedded hardware deployed in the field. These remote machines connect back to my servers at AWS running Ubuntu and I use the iptables mangle chain to lower the MTU to 500 so these devices are happy. For reference, this is the iptables rule I am using: -A POSTROUTING -p tcp --sport 12345 --tcp-flags SYN,RST SYN -o eth0 -j TCPMSS --set-mss 500 Current Problem I'm trying to spin up some servers on the Joyent Cloud using SmartOS, but I can't find any information on selectively changing the MTU like I can on Linux (e.g. all info I've found is on changing it globally, which is not what I want). How would I do it so that all connections on TCP port 12345 get the MTU I want?

• When an Excel file is locked on a network share, how does it know who locked the file?

  - by ScottStonehouse

  We are using Excel 2010 and sometimes users are working from a network share. When a user on the network opens the file in Excel, the file is locked for editing - this is the expected behavior. When another user tries to open the file, Excel gives the message [filename] is locked for editing by 'John Doe' The problem is, the user is always this one particular user's name, no matter who actually has the file open. Where does Excel get this info, and how do I fix it? Update: I should have mentioned that in Excel, under Options (General), the correct user names have been set up. That is not where this user name is coming from.

• How to tell if linux disk IO is causing excessive (> 1 second) application stalls

  - by noahz

  I have a Java application performing a large volume (hundreds of MB) of continuous output (streaming plain text) to about a dozen files a ext3 SAN filesystem. Occasionally, this application pauses for several seconds at a time. I suspect that something related to ext3 vsfs (Veritas Filesystem) functionality (and/or how it interacts with the OS) is the culprit. What steps can I take to confirm or refute this theory? I am aware of iostat and /proc/diskstats as starting points. Revised title to de-emphasize journaling and emphasize "stalls" I have done some googling and found at least one article that seems to describe behavior like I am observing: Solving the ext3 latency problem Additional Information Red Hat Enterprise Linux Server release 5.3 (Tikanga) Kernel: 2.6.18-194.32.1.el5 Primary application disk is fiber-channel SAN: lspci | grep -i fibre 14:00.0 Fibre Channel: Emulex Corporation Saturn-X: LightPulse Fibre Channel Host Adapter (rev 03) Mount info: type vxfs (rw,tmplog,largefiles,mincache=tmpcache,ioerror=mwdisable) 0 0 cat /sys/block/VxVM123456/queue/scheduler noop anticipatory [deadline] cfq

• How to use sshd_config - PermitUserEnvironment option

  - by laks

  I have client1 and client2 both are linux machines. From client1: client1$ssh root@client2 "env" it displays list of ssh variables from client2. Things I did on client2: I want to add new variable to client2 . So I edited sshd_config to PermitUserEnvironment yes and created a file environment under ssh with following entry Hi=Hello then restart sshd /etc/init.d/sshd Now from client1 trying the same command client1$ssh root@client2 "env" didn't provide the new variable "Hi". ref: http://www.raphink.info/2008/09/forcing-environment-in-ssh.html http://www.netexpertise.eu/en/ssh/environment-variables-and-ssh.html/comment-page-1#comment-1703

• how to restore grub

  - by takeshin

  During copying files via lan my Ubuntu Server 10.04 hung up and I had to reset the computer. After reboot, I got: Grub error 17, so I tried the rescue alternate CD, but I got a info, that no partitions were found on the disk. I used testdisk to restore the partitions. Using fdisk -l shows the partitions now, but when the system boots up I does nothing but displays: L234: When I plug the drive to another computer, it is not automatically mounted and I can't access the data. What to do now? How to restore the grub and boot up the system?

• Laptop screen turns off on removing power cord

  - by YatharthROCK

  After a recent upgrade to Windows 8.1 Pro from W8, my laptop's screen turns off as soon as you remove the power cord. It turns back on with no issues when you plug the power back in. Keyboard and mouse input is processed while the screen is off. My settings tell the screen to go off after 2 minutes of inactivity on battery. I was having a battery issue from before where my laptop would should down after 5 minutes of running on battery (despite showing 60% left), but I think that's unrelated. Any other info will be provided on request. Can anyone help me figure out what's going on? How can I stop this behaviour?

• Can I completely convert an Ubuntu desktop installation to a server one? (not just the packages)

  - by Rey Leonard Amorato

  I am aware that the server and desktop editions only differ by the packages installed, and I can install server packages (LAMP etc.) into a desktop edition and get the same thing. However, I want to be able to completely change my desktop installation into a server edition. e.g: when I type uname -a or lsb_release -a it is supposed to say Ubuntu server or something. I currently have an 11.10 desktop installation with LAMP stack installed and the info displayed by apache is "Apache blah blah, on (Ubuntu) server. Where does apache get this information that I am using an Ubuntu desktop installation and not a server one? Is there a config file(s) to edit?

• Virtual system drive is split between separate LUNs

  - by Tigran

  My hardware VMWare guy told me that a Win2008R2 server I have has a D drive that is split between two separate LUNs. He could not tell me if that's a good thing or bad just that it's not standard practice for him. Would you please explain the benefits or drawbacks of this setup? Thanks EDIT Some additional info. What happened was I had D drive already allocated. Then I asked for more. They said there's no more space on whatever LUN my D drive is on so the option they gave me was that part of the D drive will be on one LUN and other part will be on another LUN. Hope that helps

• what does the @ symbol mean in ls -l directory listing?

  - by Andrew Arrow

  When I run ls -l on my mac I see two .yml files: -rw-r--r-- 1 aa staff 6 Apr 15 05:50 s1.yml -rw-r--r--@ 1 aa staff 362 Apr 15 05:49 s3.yml same owner, same permissions but one has a @ at the end of the permisions. The one with the @ shows up in my editor, the one without does not. So there must be some significance. How can I turn on the @ for the file without it? I selected the files in the finder and did get info and everything looks identical between the two files.

• does the *physical* order/location of drives in a mdadm-managed RAID-10 array matter?

  - by locuse

  i've setup a 4-drive RAID-10 array using mdadm-managed, software-raid on an x86_64 box. it'd up & running and works as expected, cat /proc/mdstat md127 : active raid10 sdc2[2] sdd2[3] sda2[0] sdb2[1] 1951397888 blocks super 1.2 512K chunks 2 far-copies [4/4] [UUUU] bitmap: 9/466 pages [36KB], 2048KB chunk atm the four SATA drives are physically plugged into the motherboard's 1st four SATA ports. i'd like to gather the necessary/complete info for catastrophic recovery. reading starting here, http://neil.brown.name/blog, and the mailing list, i'm not yet completely confident i have it right. i understand 'drive order matters'. is that logical, &/or physical order that matters? if i unplugged the four drives in this array, and plugged them each back into different ports on the motherboard or a pci card, as long as i've changed nothing in software config, will the array correctly auto-re-assemble?

• SSL/https setup for herokuapp.com address rather than my actual domain

  - by new2ruby

  I have a subdomain of my site pointed to a rails app at mysite.herokuapp.com. I bought a certificate from godaddy and seem to have that all set up correctly. So that when I go to: http://mysite.herokuapp.com or http://dev.mysite.com it's redirected to: https://mysite.herokuapp.com or https://dev.mysite.com The problem is that when I visit dev.mysite.com, I get the error: Safari can't verify the identity of the website. But when I go to mysite.herokuapp.com, I don't get the error. I wanted this to be set up the other way, so that dev.mysite.com did not cause the error. I'm not sure where I went wrong. I used dev.mysite.com when generating the key and when setting it up at godaddy.com. Any ideas where I should look? P.S. The old site is hosted at dreamhost and the DNS info is stored there as well. So I created a subdomain there of type cname which points to mysite.herokuapp.com.

• Kernel appears to have no modules

  - by George Reith

  Useful info: OS: CentOS 5.8 final Kernel: 2.6.32-042stab056.8 My kernel came prebuilt with the server, I don't know anything about kernels and not a lot about linux however as far as I do know I should have some modules loaded by the kernel. I came across this problem because I am unable to run iscsi as it is expecting certain modules to be loaded. lsmod returns nothing. depmod -a returns: WARNING: Couldn't open directory /lib/modules/2.6.32-042stab056.8: No such file or directory FATAL: Could not open /lib/modules/2.6.32-042stab056.8/modules.dep.temp for writing: No such file or directory I have rebooted and nothing has changed. Does anyone know why this is happening?

• Mac Console.app not logging any messages

  - by karl_

  I recently attempted to overcome the 500 message limitation on console logs using the advice provided here: Mac: Extend or disable 500 Messages Limit of Console I copied the PLIST file onto my desktop, made the modifications, and re-copied into the LaunchDaemon folder. No dice. Unfortunately, this also broke logging in general- the console hasn't logged a message since I attempted this switch. I even went back and undid my changes. Still no logs. What's going on? Is there a way to reinstall Console.app, or revert to original settings?

• nfs server on cygwin slow

  - by Weltenwanderer

  The setup: We run an instance of cygwin nfsd on a Windows 2008 Server (Xeon 3,2 GHz). There are several Sun Solaris and SunOS machines accessing the shares. This is the exports file: /disk3 (rw,all_squash) /disk2 (rw,all_squash) Those paths are soft linked to the relevant cygdrive/d/path/to/dir paths. Some of the folders contain up to 10k files. The Problem: ls -la on the mounted folder on the sun boxes takes 2 - 3 minutes and the general read performance is really bad. cat filename displays the file in slow bursts and this hurts performance on tasks that access those shared files heavily. Processor load is not the issue, the nfs server idles most of the time, the cygwin tasks never get over 1% load.
