• Passwords and Keys in Linux

  - by PeanutsMonkey

  In a fit of desperation when I had my wireless connection die on me, I thought it was a problem with the key I had created at the start when I initially configured the wireless connection and hence deleted it. The option to create the key had presented itself when I created the wireless connection. It no longer asks me to. Now I am back online, do I have re-create the password and key I had before? If so, what do I choose and why? The options I have are as follows; PGP Stored password Password keyring Secure shell key The first and last option seem to be obvious and I have no idea about the differences between the second and third options. Why do I need a stored password or password keyring in all scenarios and not just the wireless issue I ran into? EDIT 0 Further to Belisama's comment, I have amended my question. EDIT 1 As requested, I have attached a screenshot

• Keyboard shortcut to quickly jump to the URL address field in Firefox...

  - by James Burton

  Hi, in Firefox I very often want to quickly enter a new URL in the address field. Therefore it would be very nice to be able to quickly jump to the URL address field with a keyboard shortcut! Today I must move my mouse and place the cursor in that field and also ensure that the current address is selected so I can overwrite it when entering the new URL. Very annoying! I'm sure I'm not the first one to have this need so there is probably a shortcut or an extension that does this already, but I cannot find that information! Thanks in advance, /James

• Batch convert HTML file(s) saved using IE to MHT

  - by ultrasawblade

  I have numerous web sites that I've saved over the years. I used Internet Explorer's "Save As..." option to do this. It saves the original page as an .html document, and page requirements in a linked folder with the same name as a document. I want to convert a bunch of these (over 1000) to the single-file .mht format. This can be done through Internet Explorer or Firefox (using UnMHT extension) by loading the original .html document, then re-saving as an .mht document. It is tedious to do that for the number of files I'm talking about, obviously. I'm wondering if anyone knows of a utility, command line or otherwise, that can accomplish this.

• Have rTorrent to move .torrent files

  - by David Alvares

  I am running rTorrent 0.9.2 and have configured it to move completed torrents to a different folder with this configuration line: system.method.set_key = event.download.finished,move_complete,"d.set_directory=~/done/;execute=mv,-u,$d.get_base_path=,~/done/" This is working fine, but I would like it to also move the .torrent file that it creates (from a magnet link into the session directory) into this done directory with the same name as the torrent and a .torrent extension. I tried adding another cp command, but I can not seem to figure out which variable ($d.get_hash did not work) stores the torrent's hash (which is what the .torrent files are named in the session directory). Is there a way to do this with rTorrent, if so how?

• Nano suddenly putting in weird characters when I type

  - by Cocorico

  I am using a shell and editing a file in nano (similar to pico). A short while ago, it started doing this thing where if I type: $query = "select" * from topics where id='' "; and then I hit Backspace and try to stick the letter 'a' into the id='' part, it changes it to: $query = "select * from koala_topics where id='a='' "; and the cursor jumps around to a few spaces before. Also if I type print At the start of a new line, and then I think "Oh I should have added a tab" and I go back and try to add a tab, it adds a tab AND 2 spaces, and if I put the cursor through the word print, it turns into printnt. Some other weird things have happened too. I uninstalled nano using yum (which is how I installed it), and then re-installed it, thinking that would get me clean preferences (in case that was the problem) but it doesn't fix it.

• Issues importing PST into Archive Mailbox Exchange 2013

  - by atomicharri

  I've completed a successful mailbox import request into the archive mailbox for a particular user. There are no errors to speak of and the size of the archive mailbox has grown to the expected size after import (approximately 6GB). However, in OWA I can't see any of the mail folders inside the archive mailbox, only Deleted Items and RSS feeds folders. However if I run some cmdlets to list the contents of the Archive Mailbox\Inbox folder in the Exchange Shell, the full list of subfolders will come up. If I do a mail item search on the archive mailbox, emails from those individual folders appear as search results! I just can't see the folders in the navigation pane and hence cannot browse any of my old emails. Any help would be appreciated.

• rm failing inside cron script

  - by Nicholas

  I have a cron job calling a bash script which runs fine, except for one line inside it that is suppose to remove all fines in a directory. The result of this line is always 'no such file or directory' even though I have verified (many times) that there are files in that directory. The line in question is as simply: rm /dir1/dir2/dir3/* The script works fine when run manually in the terminal, so it must be something about how the cron is run. I've tried giving 'dir3' and all the files inside it every permission possible, so it shouldn't be a permission problem. (The directory and files are also owned by the user). I've tried specifing 'SHELL=/bin/bash' inside 'crontab'. There is no sticky bit set and there is no alias on the rm command. Interestingly changing the 'rm' command to 'ls' gives the same negative result (unless you remove the trailing '*', and then that works). What am I missing here?

• Seamless Remote Windows on Linux Client

  - by prestomation

  I really like the RemoteApp features of Windows Server 2008 Are there any solutions for similar functionality for Linux clients and a Windows server? We have users that are running Linux on the desktop and rdesktop to a Windows server, mostly for Outlook. It would be nice if Outlook could behave more seamlessly. From what I can tell rdesktop doesn't do that yet, it only implements RDP 5. I've also seen "SeamlessRDP" from Cendio, which is an extension to rdesktop, but I can't get it to work. I think it doesn't work in Vista, but that is just a guess. Any ideas? And thanks in advance. EDIT: I emailed Cendio and they confirmed SeamlessRDP doesn't work with Server 2008 for unknown reasons. It appears there is no way to do this with a 2k8 server. It's either windows clients with RemoteApp or using a pre-Vista OS with seamlessrdp

• How to jump through an IP ad in firefox?

  - by chris

  I use firefox with a lot of anti-ad extension, like adblock, NoScript, Ghosty etc. I found this IP 220.191.158.69 always in the list of NoScript, I want to ban this IP. I have checked it, searched it. It is from China telecom damn Ad. I guess NoScript can ban this IP already, but When I do not allow that IP, sometimes a webpage can not be loaded at first time, I need to refresh two or more times. I hate it... So I hope there are some way or browser extensions or script can jump through this damn IP.

• getting PHP PDO flavors to work on Mac OS X

  - by Jason S

  I'm running OS X 10.5; it looks like it came with Apache and PHP installed (minus some minor configurations which I turned on per this page; I've used Apache before so I know the basics of how httpd.conf works). I've got a pre-existing script which uses PDO. I've got a MySQL database and can easily configure my script to access the database via PDO MySQL or PDO ODBC. The problem is, that even though I enabled the PDO MySQL and PDO ODBC extensions in php.ini, phpinfo() reports the only PDO drivers are sqlite2 and sqlite. I'm guessing the relevant extension .dll or .so files are not present? How do I get them? note: I'm using the built-in install for PHP. (see apple's page on enabling php, which doesn't say anything about configure or adding additional .so files)

• How to pass bash script arguments to a subshell

  - by Ralf Holly

  I have a wrapper script that does some work and then passes the original parameters on to another tool: #!/bin/bash # ... other_tool -a -b "$@" This works fine, unless the "other tool" is run in a subshell: #!/bin/bash # ... bash -c "other_tool -a -b $@" If I call my wrapper script like this: wrapper.sh -x "blah blup" then, only the first orginal argument (-x) is handed to "other_tool". In reality, I do not create a subshell, but pass the original arguments to a shell on an Android phone, which shouldn't make any difference: #!/bin/bash # ... adb sh -c "other_tool -a -b $@"

• Can I use nginx to start EC2 instances on demand?

  - by Gabe Hollombe

  TL;DR - Is there a way to make nginx act as an elastic load balancer that will spin up EC2 instances on demand, allowing for the case when periods of no demand mean no instances will be running? Longer explanation - I have an nginx server that proxy_pass'es requests to a server on EC2. This server doesn't get many requests, so I'd like to keep the server spun down during periods of inactivity (I already have a script to do this). Then, when the instance is spun down and nginx gets a request for that instance, it will time out when trying to get a response from it. At this point, can I somehow trigger a shell command on the server to use EC2's command line tools to spin up the instance, then re-try the user's request after it has started?

• Can not input or print Chinese on PuTTY

  - by hetaoblog

  On Red Hat Enterprise Linux AS release 3, I've set my environment variable as below $ echo $LANG zh_CN.UTF-8 $ echo $LANGUAGE zh_CN.UTF-8 $ echo $SUPPORTED en_US.UTF-8:en_US:en:zh_CN.UTF-8 $ locale LANG=zh_CN.UTF-8 LC_CTYPE="zh_CN.UTF-8" LC_NUMERIC="zh_CN.UTF-8" LC_TIME="zh_CN.UTF-8" LC_COLLATE="zh_CN.UTF-8" LC_MONETARY="zh_CN.UTF-8" LC_MESSAGES="zh_CN.UTF-8" LC_PAPER="zh_CN.UTF-8" LC_NAME="zh_CN.UTF-8" LC_ADDRESS="zh_CN.UTF-8" LC_TELEPHONE="zh_CN.UTF-8" LC_MEASUREMENT="zh_CN.UTF-8" LC_IDENTIFICATION="zh_CN.UTF-8" LC_ALL=zh_CN.UTF-8 Meanwhile I've set PuTTY's transmission encoding as utf-8 and appearance-font setting to have a font as 'Fixedsys' which does support chinese. However, when I try to print a file with Chinese, it can not print it correctly $ cat 1.txt hello¦¦¦ $ and I can not input Chinese correctly on shell.

• httpd.conf variables : What is the difference between ${var} and %{var}?

  - by 108.im

  What is the difference between ${var} and %{var} in httpd.conf? How and when would one use ${} and %{}? http://httpd.apache.org/docs/2.4/configuring.html mentions : The values of variables defined with the Define of or shell environment variables can be used in configuration file lines using the syntax ${VAR}. http://httpd.apache.org/docs/2.4/mod/mod_rewrite.html mentions: Server-Variables:These are variables of the form %{ NAME_OF_VARIABLE } and RewriteMap expansions:These are expansions of the form ${mapname:key|default}. Will ${VAR} be used everywhere in httpd.conf, except in mod_rewrite directive's (like RewriteCond, RewriteRule but except for RewriteMap expansions which use ${} as in RewriteRule ^/ex/(.*) ${examplemap:$1} ) Would a variable set in httpd.conf using SetEnvIf Directive, for use in same httpd.conf, be used as ${var} except when the variable is used with mod_rewrite directive's, where the variable would be used as %{var}?

• PDO - WHat is it? How do I enable it on shared hosting.

  - by Keith Groben

  I have a shared hosting account and PHP5 is installed and running. When I view phpinfo, I can see that mysql pdo is running. I think I need to "link" to it from the php.ini file. But I dont know for sure. I read that I needed to type "extension=pdo.so". I did that, and it did nothing. I contacted my hosting support, they said I need to rename php.ini to php5.ini. Did that and nothing. I am stuck and trying to install Kimai, but cannot without fixing this pdo problem. I have searched for a good hour and can find nothing to help me.

• How to increase video memory in libvirt/KVM gui?

  - by Dejan

  In the 'Virtual Hardware details', it lists the model as 'cirrus' with 9MB of RAM. The RAM field cannot be changed, but how to increate the video RAM? My host OS is RH6 and gust OS is Fedora16. EDIT: From guest OS, when I run xvinfo it displays 'no adaptors present'. I was trying to play a video using gstreamers xvimagesink plugin (XFree86 video output plugin using Xv extension). The problem is that xvimagesink is using hardware acceleration for video performance and hence the error Could not initialize Xv output. I guess I'll have to configure hardware acceleration for the guest.

• WebDAV "PROPFIND" exception in IIS due to network share?

  - by jacko

  Hi all, We're finding continuous exceptions in our event viewer on our live box to the following exception: [snippet] Process information: Process ID: 3916 Process name: w3wp.exe Account name: NT AUTHORITY\NETWORK SERVICE Exception information: Exception type: HttpException Exception message: Path 'PROPFIND' is forbidden. Thread information: Thread ID: 14 Thread account name: OURDOMAIN\Account Is impersonating: True Stack trace: at System.Web.HttpMethodNotAllowedHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Other Specs: Windows Server 2003 R2 & IIS 6.0 We've narrowed it down to occuring when people try to access shares on the box from within the network, and have discovered (we think) that its due to the WebDAV web services extension being previously disabled by past staff. The exceptions are being thrown when trying to access directories that are virtual dirs in IIS, and plain old UNC network shares What the implications for enabling the WebDAV extensions on our live web server? And will this solve our problems with the exceptions in our event log?

• Puppet won't execute command

  - by tom

  Puppet 0.25.4 on ubuntu point blank refuses to execute the following command: exec {"initiate replica set": command => "echo 'rs.initiate()' | mongo", path => ["/usr/bin","/usr/sbin","/bin"], user => "root", require => Class["mongodb"] } I can execute the command as root myself, so I'm guessing perhaps it's an issue with the shell. Unfortunately upgrading puppet isn't an option (and causes other issues anyway). I've tried specifying explicit paths to the binaries instead of relying on the path parameter, and also changing the command to: "bash -c \"echo 'rs.initiate()' | mongo\"" Still doesn't work. Any ideas? I get an error message saying something like "failed to change from notrun to 0"

• Is there a registry key change that will by-pass the Windows Domain Join Welcome page?

  - by user1256194

  I'm scripting some Windows Server 2008 R2 builds using Power Shell. Some software needs to be installed after the server has joined the domain. Since I want to automate everything, I'm looking to by-pass the domain controllers Welcome page using a registry hack script. I work for a large company and the Active Directory people are unwilling to change group policy. I figure if it's a registry key I can script the change, install the software, replace the key and reboot as the final step. Is there a registry key change that will by-pass the Domain Join Welcome page?

• Temporarily disable an AD server

  - by 3molo

  Topology and setup We have main office A, and branch office (abroad) B. Our ISP somehow messed up the MPLS, and office A<B will not be connected until a few days. At location B, we have an AD (and the other two ADs at location A). Location A also have an exchange server. The problems A few users at A have problem to login to their computers running Windows XP, the logon process kind of hangs where "Applying computer policies". Additionally, I can't start the Exchange management shell, it fails on get-recipient because the AD abroad (location B) is unreachable. Solution? I could delete the AD at B, but Im pretty sure it will be a hazzle to re-join it, and since the office is abroad it's not an option to just go there and re-install it - re join, I now wonder how I in location As primary and secondary ADs can temporarily disable AD at location B.

• How to bypass AllowTCPFowarding=no by installing own forwarder?

  - by Eric B.

  In the man pages for sshd_config, for the AllowTCPForwarding option, it states: AllowTcpForwarding Specifies whether TCP forwarding is permitted. The default is “yes”. Note that disabling TCP forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders. How do I install my own forwarder? I have a remote server in which I disabled TCPForwarding a long while ago. I would like to "enable" it for myself only, by using my own forwarder, while keeping the forwarding closed to the other users. I've looked around, but cannot seem to find the right pkgs to accomplish this. Can anyone please elaborate? Thanks! Eric

• Compiling zip component for PHP 5.2.11 in MAMP PRO

  - by Zlatoroh

  Helo I installed MAMP PRO on my Macbook Pro (10.6) some time ago. Now I would like to use zip functions in php. I found that I must add zip.so to my extension folder and edited php.ini. On my computer I have two different versions of PHP one in MAMP folder and other in user/lib which was pre-installed on my system. Now I wish to compile my zip library for MAMP version. I got zip sources for my version of PHP then in terminal called function /Applications/MAMP/bin/php5/bin/phpize so it uses mamp php version ./configure make then I moved compile zip.so to extensions/no-debug-non-zts-20060613. When MAMP is launched it returns this error: [11-Apr-2010 16:33:27] PHP Warning: PHP Startup: zip: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Can some body explain to me how to do this the right way.

• Is there a way to import email from the raw email files?

  - by Chris Schmitz

  I have a client who recently switched hosts. When they switched hosts they didn't backup their email and updated their configuration settings so they lost everything. However, I was able to log in to their old hosting control panel and download their mail folder. I am wondering if there is a way to extract their emails and/or contacts from the files. I'm not sure what type of files they are, there is no extension, but the folder directory is structured like this: mail/ .Drafts/ .Sent/ .Trash/ cur/ new/ theirdomain.com/ tmp/ [email protected] maildir Inside of the theirdomain.com folder, there is a folder for each account and inside of that is a folder called "cur" which has a whole bunch of files with names like 1292945327.H169813P25958.uscentral21.myserverhosts.com,S=10117/2,S and if I preview those files I can see the actual email messages inside of them but I have no idea how to get that information from those files to an email client. Anyone know of a way to work with these files? Thanks in advance for any insight you can share!
