  • "Must-Have" Firefox Addons?

    - by Jonathan Sampson
    Only one addon per answer, please. What are some of the best addons when it comes to Firefox? My current favorites include: Firebug Firebug integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page. Greasemonkey Allows you to customize the way a webpage displays using small bits of JavaScript. What am I missing?

  • Heartbeat won't successfully start up resources from a cold boot when a failed node is present

    - by Matthew
    I currently have two ubuntu servers running Heartbeat and DRBD. The servers are directory connected with a 1000Mbps crossover cable on eth1 and have access to an IP camera LAN on eth0. Now, let's say that one node is down and the remaining functional node is booting after having been shut down. The node that is still functioning won't start up heartbeat and provide access to the drbd resource from a cold boot. I have to manually restart heartbeat by sudo service heartbeat restart to get everything up and running. How can I get it to start fine from a cold start, when only one server is present? Here is the ha.cf: debug /var/log/ha-debug logfile /var/log/ha-log logfacility none keepalive 2 deadtime 10 warntime 7 initdead 60 ucast eth1 192.168.2.2 ucast eth0 10.1.10.201 node EMserver1 node EMserver2 respawn hacluster /usr/lib/heartbeat/ipfail ping 10.1.10.22 10.1.10.21 10.1.10.11 auto_failback off Some material from the syslog: harc[4604]: 2012/11/27_13:54:49 info: Running /etc/ha.d//rc.d/status status mach_down[4632]: 2012/11/27_13:54:49 info: /usr/share/heartbeat/mach_down: nice_failback: foreign resources acquired mach_down[4632]: 2012/11/27_13:54:49 info: mach_down takeover complete for node emserver2.

  • Why are my Windows 7 updates continuously failing?

    - by Chris C.
    I'm an advanced level user here with an odd issue. I have two Windows Updates that are failing to install, every single time. I'm getting a mysterious "Code 1" error on both updates, an error for which I'm having difficulty finding a solution. The updates in question are: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [May 2011] Because these updates are failing, the Shut Down button in my start menu always has the shield icon next to it, indicating that "new" updates will be installed on shut down. But, of course, they'll fail and when the PC is restarted, the shield icon is still there. When checking the update history and viewing the details of the failed updates, I get the following: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) Installation date: ?6/?29/?2011 3:00 AM Installation status: Failed Error details: Code 1 Update type: Important A security issue has been identified leading to MFC application vulnerability in DLL planting due to MFC not specifying the full path to system/localization DLLs.

  • Modifying y-axis label in pdf Diagram

    - by Andrea
    Hi all, I have mislabelled the y-axis in my pdf graph that I generated from an Matlab file. Unfortuantely, I cant find anymore the data that I used to generate the graph. So I am wondering if there is an free tool that allows me to rename the y-axis in my pdf diagram? Are there any free tools available that could be helpful or is this something "impossible" to do? Many thanks for your help, Andrea

  • Why can't “knife data bag from file” find existing json file on chef server?

    - by ellisera
    Summary: I'm running into a problem with "knife data bag from file", where knife doesn't recognize the .json data bag file pulled down from a remote git repo. Background: I'm currently trying to transition from chef-solo use to chef server while using the cookbooks, data bags and other chef info from our remote git repo. I've currently pulled down a copy of our git repo and set the cookbook path and data bag path in knife.rb. I also loaded the cookbooks, made adjustments, etc. Details: When trying to load our .json data bags by doing "knife data bag add from file FOLDER FILE" it looks like it worked until I do "knife data bag list" and it comes up blank. So I decided to try adding the edit option at the end to see what's being loaded, if it is. This is the error I get: knife data bag from file local_settings test.json -e nano ERROR: Could not find or open file 'test.json' in current directory or in 'data_bags/local_settings/test.json' The data bag file does exist, in the proper location, in a tested, working json file. I've also sometimes gotten an error saying "could not open data bag "local_settings". I would obviously like to keep the data bag path within the appropriate git repo folder to be able to keep track of changes in a more centralized location (our git repo, as opposed to the chef server). Any solutions, advice or pointers in the right direction are appreciated.

  • ip-up does not trigger when using built-in cisco vpn on mac osx lion

    - by Yasser Sobhdel
    I am using Cisco VPN client over lion and I want to make the ip-up and ip-down work. There is no sign of any action taken when I connect or disconnect this VPN connection. I really doubt whether the syntax has been changed or even this kind if connection is triggering the ip-up. Logically, it must be set over ppp but when using the following codes and instructions on them, there is no sign of any output in the log file: http://www.macfreek.nl/mindmaster/Modify_PPTP_Routing_Table http://www.aidanfindlater.com/use-vpn-for-specific-sites-on-mac-os-x Going for error, which there is no sign of it, using the following page: http://hints.macworld.com/article.php?story=20060616150640529 I couldn't find the /var/log/ppp/vpnd.log log file. Also the files are given full permission 0755 or a+x or even 777 using the following command: sudo chmod a+x /etc/ppp/ip-up Any clue on how to debug this would be appreciated. I am totally confused, netstat -rn -f inet doesn't show the routes. Even when the routes are added manually, closing the VPN connection does not run the ip-down and the routes must be deleted manually.

Unfortunately, I didn't find anything that indicated why there wouldn't be such menus with my spreadsheets. Does someone know more about this? Thanks / Rene

  • How to stop Excel 2003 from loading a Gazillion files

    - by Gary M. Mugford
    One of my soon-to-be-ex-friends got an Excel file from another friend of his and decided to click on it. It started opening all kinds of files from within Excel. Over 200 and still counting when he called me. I told him to go to task manager, which showed a LOT of files in the applications tab, but only one Excel.exe in the processes tab. Closing it down there, closed down Excel. I then CrossLooped in to see if I could give him a helping hand. Each time Excel was re-opened, the mass influx of files started. They were all kinds of files, PDFs, Docs, JPGs, even some spreadsheets. It looked like the end of solitaire, with multiple windows opening (XP) and the counter on the lone Excel button on the task bar counting off the files. I did the task manager exit routine and went looking for temp files. I CrapCleaned out the system. Made sure I went through the files created in the last hour and deleted anything with a temp anywhere in it. I also deleted the crappy infected/corrupted file from it's place on the desktop (yeah, I know, I yelled for 15 minutes on THAT subject). Despite a delousing, the restart of Excel, which complained of a deactivated add-in, would start the cascading windows, whether I answered yes or no to that question. Yes, it knew it had a serious crash, but why would it just keep on trying to load the bad file, even when I got rid of it? But here's the real question. WHERE was it loading from? I went through the backup folder and NOTHING was there! So what's the process for starting Excel WITHOUT it trying to do a crash recovery? Sort of makes me feel stupid at times. Thanks for any light you can shed on this issue. GM

  • How to trigger a SQL Agent Job from a client PC

    - by Preet Sangha
    I have SQL Agent job that is automated that a non SQL Admin user may need to occasionaly run. I know I can trigger a SQL Agent Job via sp_execute_job. Can anyone tell me where to find what I need installed on a (Non SQL Server box) client PC in order to run one of - SQLCmd, OSQL or ISQL - commands please, so I can execute the above SQL? Or is there are simpler way perhaps with out calling TSQL or without installing any SQL client tools.

  • Bad Performance when SQL Server hits 99% Memory Usage

    - by user15863
    I've got a server that reports 8 GB of ram used up at 99%. When restart Sql Server, it drops down to about 5% usage, but gradually builds back up to 99% over about 2 hours. When I look at the sqlserver process, its reported as only using 100k ram, and generally never goes up or below that number by very much. In fact, if I add up all the processes in my TaskManager, it's barely scratching the surface of my total available (yet TaskManager still shows 99% memory usage with "All processes shown"). It appears that Sql Server has a huge memory leak going on but it's not reporting it. The server has ran fine for nearly two years, with this only starting to manifest itself in the last 3-4 weeks. Anyone seen this or have any insight into the problem? EDIT When the server hits 99%, performance goes down hill. All queries to the server, apps, etc. come to a crawl. Restarting the service makes things zippy again, until 2 hours has passed and the server hits 99% once again.

  • Site to Site VPN with Fault Tolerence

    - by Nordberg
    Hello, I have a situation where I require an IPSEC tunnel between two sites. Site 2 is a small branch office with basic (ADSL) connectivity and Site 1 is the "main" office with SDSL and ADSL for redundancy should the SDSL fail. From Site 1, all traffic bound for the 172.0.0.0 network will then be sent down another IPSEC tunnel to a supplier's Remote Server. See this page for the basic premise (this is a rough idea and things can be moved about etc...) I am considering specifying Cisco ASA devices as the firewalls for both sites for all connections. Would it be possible to employ something like HSRC to provide a backup at Site 1 should the SDSL go down? I suppose the key aims here are that Site 2 can somehow failover to initiate a VPN to the ASA behind the ADSL at Site 1. I will have a 21 subnet mask on all internet connections so can play with Class C routing if need be... If I'm barking up the wrong tree with HSRC, is there another way I can acheive this without massive expenditure on Barracuda routers et al? Many Thanks.

  • IPMI queries to multiple nodes at once

    - by lorin
    I'm using IPMI to manage some nodes in a cluster. I'd like to be able to submit IPMI queries to all of the nodes in parallel. Something similar to Cluster SSH or tentakel, except that it wraps ipmitool instead of ssh. Are there any tools like that?

  • SVG to JPEG/BMP conversion

    - by stanigator
    I have a svg file that I want to convert to jpeg or bmp (or any other image formats). However, all the conversions that I have used on the various online tools yielded very unclear output images. I don't want to use svg as it is very inconvenient. What would be your suggestions to get around that?

  • How to get html/css/jpg pages server by both apache & tomcat with mod_jk

    - by user53864
    I've apache2 and tomcat6 both running on port 80 with mod_jk setup on ubutnu servers. I had to setup an error document 503 ErrorDocument 503 /maintenance.html in the apache configuration and somehow I managed to get it work and the error page is server by apache when tomcat is stopped. Developers created a good looking error page(an html page which calls css and jpg) and I'm asked to get this page served by apache when tomcat is down. When I tried with JkUnMount /*.css in the virtual hosting, the actual tomcat jsp pages didn't work properly(lost the format) as the tomcat applications uses jsp, css, js, jpg and so on. I'm trying if it is possible to get .css and .jpg served by both apache and tomcat so that when the tomcat is down I'll get css and jpg serverd by apache and the proper error document is served. Anyone has any technique? Here is my apache2 configuration: vim /etc/apache2/apache2.conf Alias / /var/www/ ErrorDocument 503 /maintenance.html ErrorDocument 404 /maintenance.html JkMount / myworker JkMount /* myworker JkMount /*.jsp myworker JkUnMount /*.html myworker <VirtualHost *:80> ServerName station1.mydomain.com DocumentRoot /usr/share/tomcat/webapps/myapps1 JkMount /* myworker JkUnMount /*.html myworker </VirtualHost> <VirtualHost *:80> ServerName station2.mydomain.com DocumentRoot /usr/share/tomcat/webapps/myapps2 JkMount /* myworker JkMount /*.html myworker </VirtualHost>

  • Virtualbox HTTP load testing, host CPU overload issues

    - by aschuler
    I'm doing HTTP load testing benchmarks (using Apache Benchmark and Siege) on a small Java EE 1.7.0 / Tomcat 7.0.26 application running on a Debian Squeeze 6.0.4 x64 virtualized with Virtualbox 4.1.8. The computer host is Ubuntu 11.10 x64. I've modified those parameters in the Tomcat server.xml : <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="200000" redirectPort="8443" acceptCount="2000" maxThreads="150" minSpareThreads="50" /> The application executed on the server takes around 300ms. This app is running well until a certain amount of concurrent connections like those one : ab -n 500 -c 150 http://xx.xx.xx.xx:8080/myapp/ ab -n 1000 -c 50 http://xx.xx.xx.xx:8080/myapp/ siege -b -c 100 -r 20 http://xx.xx.xx.xx:8080/myapp/ A lot of socket connection timed out happens and this completly overload the host processor (but the CPU load inside the VM is normal). Doing an htop on the host, i can see that the Virtualbox processus is running under 300% CPU and never come down even after the load test is finished. (I've allocated 4 processors to the VM, if I allocate only one processor, CPU load goes under 100%). Restarting Tomcat don't do anything, i'm forced to restart the whole VM. I've tryed to launch those ab/siege commands locally on the VM and everything goes well. I first thought it was related to a linux network limit as explained here: Running some benchmarks using ab, and tomcat starts to really slow down So I've modified those TCP parameters : echo 15 > /proc/sys/net/ipv4/tcp_fin_timeout echo 30 > /proc/sys/net/ipv4/tcp_keepalive_intvl echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse It seems to be better, but it continues to overload the host CPU and output socket connections time out at a certain amount of concurrent connections. I'm wondering if this is not related to how Virtualbox handles external concurrent connections.

  • How to migrate data from a Firebird database to PostGreSQL on Linux

    - by Tom Feiner
    Are there any good tools to migrate existing firebird databases to PostgreSQL for Linux systems? I've looked at: FBexport which can be used to dump the data as insert statements, but it's mainly written to export/import from one firebird db to another, not as a migration tool. There's also: Firebird to PostgreSQL Win32 tool, but it's only for win32 systems. Is there any good tool to do this? Or should I just roll my own?

  • Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

    - by Madiyaan Damha
    I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,
