• How do I stop Firefox on Ubuntu from trying to load whatever is in my clipboard when I middle-click

  - by therefromhere

  In Firefox on Ubuntu, if I middle-click anywhere on a page that's not a link, it seems to treat whatever text is in the clipboard as a URL and tries to load it. This is annoying, since if I either accidentally click the middle button or (more often) miss a link when trying to middle-click it, I'll either go to whatever URL is in my clipboard or get an alert saying: The URL is invalid and cannot be loaded Is there any way of either: a) Disabling this functionality so that middle-click on a non-link does nothing (maybe an about:config setting?, or b) Making the functionality more intelligent, so that it will only try and open text if it looks like a URL (this seems like a job for a plugin).

• In Nginx can I set Keep-Alive dynamically depending on ssl connection?

  - by ck_

  I would like to avoid having to repeat all the virtualhost server {} blocks in nginx just to have custom ssl settings that vary slightly from plain http requests. Most ssl directives can be placed right in the main block, except one hurdle I cannot find a workaround for: different keep-alive for https vs http Is there any way I can use $scheme to dynamically change the keepalive_timeout ? I've even considered that I can use more_set_input_headers -r 'Keep-Alive: timeout=60'; to conditionally replace the keep-alive timeout only if it already exists, but the problem is $scheme cannot be used in location ie. this is invalid location ^https {}

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

• How to interpret the bash command "usage" syntax?

  - by raoulsson

  How exactly do you have to interpret the output of a commands "usage" output, in bash for example. For example, on my OS X, cp gives me usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory What does the nested options, like -H within -R, indicate? Does upper and lower case have any meaning? When is an argument optional, required? I need to implement a telnet command line against a program of mine and I would like to get this straight.

• What are "Missing thread recordng" erros when running fsck -fy?

  - by ohho

  There is some error reported when I run Disk Utility and verify the root volume on my OS X MacBook. So I boot and CMD-S into the shell mode and run /sbin/fsck -fy. Errors are like: ** Checking catalog file. Missing thread record (id = ...) In correct number of thread records ** Checking catalog hierarchy. Invalid volume file count (It should be ... instead of ...) ** Repairing Volume Missing directory record (id = ...) I'd like to know what is the cause of the above errors? Hopefully I will be more careful in the future to prevent them from happening again. p.s. I am using a SSD and so I assume mechanical hard disk error is less likely. Thanks!

• How to execute a shell script on startup?

  - by vijay.shad

  I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

• Why can't PHP script write a file on server 2008 via command line or task scheduler?

  - by rg89

  I have a PHP script. It runs well when I use a browser. It writes an XML file in the same directory. The script takes ~60 seconds to run, and the resulting XML file is ~16 MB. I am running PHP 5.2.13 via FastCGI on Server 2008 64 bit. I created a task in task scheduler to run c:\php5\php.exe "D:\inetpub\tools\something.php" No error returned, but no file created. If I run this same path and argument at a command line it does not error and does not create the file. I am doing a simple fopen fwrite fclose to save the contents of a php variable to a .xml file, and the file only gets created when the script is run through the browser. Thanks

• sysprep failure on Windows Server 2008

  Before deploying a Azure VM Role, we need to perform %windir%\system32\sysprep\sysprep.exe /generalize /oobe /shutdown But in my case the sysprep fails with the log file %windir%\system32\sysprep\Panther\setuperr.txt saying: 2012-07-05 08:03:57, Error [0x0f0073] SYSPRP RunExternalDlls:Not running DLLs; either the machine is in an invalid state or we couldn't update the recorded state, dwRet = 31 2012-07-05 08:03:57, Error [0x0f00ae] SYSPRP WinMain:Hit failure while processing sysprep cleanup external providers; hr = 0x8007001f I do not always want to create a new image.

Under certain circumstances, I need to tear down the VM Image from azure and re-deploy with some more changes. So sysprep has to run almost twice every week.

• C program runs in Cygwin but not Linux (Malloc)

  - by Shawn

  I have a heap allocation error that I cant spot in my code that is picked up on vanguard/gdb on Linux but runs perfectly on a Windows cygwin environment. I understand that Linux could be tighter with its heap allocation than Windows but I would really like to have a response that discovers the issue/possible fix. I'm also aware that I shouldn't typecast malloc in C but it's a force of habit and doesn't change my problem from happening. My program actually compiles without error on both Linux & Windows but when I run it in Linux I get a scary looking result: malloc.c:3074: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)-bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) = (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)-size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

• Unexpected behavior in Bash

  - by cYrus

  From man bash: A simple command is a sequence of optional variable assignments followed by blank-separated words and redirections, and terminated by a control operator. The first word specifies the command to be executed, and is passed as argument zero. The remaining words are passed as arguments to the invoked command. So it's perfectly legal to write: foo=bar echo $foo but it doesn't work as I expect (it prints just a newline). It's quite strange to me since: $ foo=bar printenv foo=bar TERM=rxvt-unicode [...] Could someone please explain me where I'm doing wrong?

• CruiseControl.Net - not able to see Project Statistics

  - by Anders Juul

  Hi all, I've made a reinstallation of the buildserver and can no longer see the standard graphs of project statistics. The error message shown is "Missing/Invalid statistics reports. Please check if you have enabled the Statistics Publisher, and statistics have been collected atleast once after that." To the best of my knowledge, the ccnet.config file has not been changed in this respect and by inspection it is verified that I have a Statistics / statisticsList-section for the project. Furthermore, the values appear in the Artifacts\statistics.csv and Artifacts\report.xml files. My guess would then be StatisticsGraph.xslt, which I have copied fresh from distribution to both Server\xlst and WebDashboard\xslt (why are they located in both places, by the way!?). Rebuild and check - still same error message. Any hints to how to debug this would be appreciated!

• Wireless internet connection connects but internet does not work (no packets received). Wired does.

  - by Rodney

  When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

• Windows Live Writer fails to start

  - by Albert Bori

  I installed windows live writer and configured it to connect to my xmlrpc enabled blog engine. After doing so, it threw an unrecoverable error and closed down. After attempting to restart windows live writer, it throws the following exception each time: Description: Windows Live Writer has encountered a problem: Invalid URI: The hostname could not be parsed. Problem signature: Problem Event Name: WindowsLiveWriter Problem Signature 01: CreateThis Problem Signature 02: 115 Problem Signature 03: System.UriFormatException Problem Signature 04: 15.4.3555.308 Problem Signature 05: 2.0.50727.5456 Problem Signature 06: Windows Live Writer OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Since I was unable to start windows live writer at all, I tried uninstalling it and removing all files associated with it in my "C:/users/[username]/appdata" folder. After that, I re-installed it and still get the error every time I try to launch the application. Does anyone know how I can get around this?

  - by tim

  ok so i'm working through a tutorial to get rvm installed on my mac. the bash command to get rvm via curl is curl -L https://get.rvm.io | bash -s stable i understand the first half's curl command at location rvm.io, and that the result is piped to the subsequent bash command, but i'm not sure what that command is doing. My questions: -s : im always confused about how to refer to these. what type of thing is this: a command line argument? a switch? something else? -s : what is it doing? i have googled for about half an hour but not sure how to refer to it makes it difficult. stable : what is this? tl;dr : help me decipher the command bash -s stable to those answering this post, i aspire to one day be as bash literate as you. until then, opstards such as myself thank you for the help!

• PostgreSQL didn't install on Ubuntu 11.04

  - by peanut

  On a new copy of Ubuntu 11.04 server I am trying to install PostgreSQL server by apt-get install postgresql. But in the end of installation log I saw: Error: could not create default cluster. Please create it manually with pg_createcluster 8.4 main --start When I ran this command I saw this message: perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en_US:en", LC_ALL = (unset), LC_CTYPE = "UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). Error: The locale requested by the environment is invalid. And no PostgreSQL server started :( What I need to do to become happy on this?

• Why can't I grant exec on dbms_lock.sleep() OR create a procedure using it (but I can run it fine on its own)

  - by Richard Green

  I am trying to write a small bit of PL/SQL that has a non-CPU burning sleep in it. The following works in sqldeveloper begin dbms_lock.sleep(5); end; BUT (as the same user), I can't do the following: create or replace procedure sleep(seconds in number) is begin dbms_lock.sleep(seconds); end; without the error "identifer "DBMS_LOCK" must be declared... Funny as I could run it without a procedure. Just as strange, when I log in as a DBA, I can run the command grant exec on dbms_lock to public; and I get ERROR at line 1: ORA-00990: missing or invalid privilege This is oracle version "Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production"

• Why won't my Windows 7 KMS key work on my Server 2008 KMS server?

  - by Ryan Bolger

  Our Microsoft volume licensing site was recently updated to include our Windows 7 and Server 2008 R2 KMS keys. We have an existing KMS server running on Server 2008 (not R2). In an attempt to be proactive about supporting the new OSes in our environment, I unregistered the old KMS key with slmgr.vbs and tried registering the new key. The registration failed with Error 0xC004F050. The description for that error was "The Software Licensing Service reported that the product key is invalid." What's wrong? I've checked and double checked that for typos against what is listed on the Volume Licensing website.

• Where did this incorrect cached DNS lookup come from?

  - by Stephen Jennings

  Somehow, I've been having a chronic issue where my computer will get an invalid DNS lookup in its cache for either of the two Exchange servers I use from Mail.app. My workplace runs one of the Exchange servers and I run the other (they are totally unrelated, hosted by different companies, etc.). The problem manifests as a certificate domain error. When it happens, I can run nslookup mail.mydomain.com and I see the incorrect IP address (usually owned by either Apple or Akamai), but if I run nslookup mail.mydomain.com 8.8.8.8, I get the correct address. My real quest is to find out why this keeps happening, and to do that, I'd like to know which server is supplying me this bad DNS entry. Is there a way to check my DNS cache to see where this bad lookup came from?

• renaming hard drives (sdc to sdb) on the fly

  - by w00t

  ata2: link is slow to respond, please be patient (ready=0) kernel: [2761026.198796] ata2: soft resetting link kernel: [2761031.226669] ata2.00: disabled kernel: [2761031.226720] ata2: EH complete kernel: [2761031.226753] sd 1:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK After receiving the error above, I couldn't access /dev/sdb anymore. Not wanting to restart the server, I rescanned for the device using echo "- - -" > /sys/class/scsi_host/host1/scan and it readded the drive as /dev/sdc. From what I have found, I need to use echo "scsi add-single-device 0 0 3 0" > /proc/scsi/scsi, "3" being the SCSI ID which corresponds to sdb. Everything nice up to the point I execute the command and get -bash: echo: write error: Invalid argument. All the solutions point to using this method, but I am unable to. Any other method available? Debian 5.0.8 - 2.6.26-1-686
