  • How do I prevent Pidgin from loading XMPP chat room history on join?

    - by Mr. Jefferson
    In Pidgin, when I join a chat room, it loads the chat room history. iChat on the Mac has a preference in the Accounts section to set a variable amount of history to load, or disable loading history entirely. How do I do the same thing in Pidgin? Is there a preference somewhere that I've missed? The object is to have the chat room start fresh each day, so I'd also be fine with disabling chat room history entirely on the server if that's possible. But I didn't see that option either when I looked in Server Admin on the server. I found this list of XMPP room types, and it looks like creating a Temporary Room might be the best way to do this, but I don't want to have to create the room manually every morning. Right now I've got Pidgin set to auto-join the room when I log in; I want it to do that without loading history. EDIT: The XMPP multi-user chat spec referenced above also contains a section on managing history. And I got this to work by pulling up the XMPP Console plugin in Pidgin, copying the <presence /> stanza it sent when I joined the room, closing the room, pasting the stanza into the console, adding the <history /> element and sending it. When I opened the room again, I had no history. But it all came back the next time! So: how do I get Pidgin to send the <history /> stanza by default?

  • Selenium server causes crazy load on server - how to prevent?

    - by Eric
    I'm running this linux: Linux host.themepark.com 2.6.32-220.4.1.el6.x86_64 #1 SMP Tue Jan 24 02:13:44 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux And I run the Selenium stand-alone server on my box with this command: java -jar /home/l/cron/selenium-server-standalone-2.24.1.jar > /logs/selenium.log 2>&1 & Here's the problem: as soon as I do that, the server load starts skyrocketing. I even went back and downloaded older versions of the Selenium server, but same results with 2.23.1, 2.23.0, and 2.19.0. Note that the server load starts going nuts before I issue ANY commands to Selenium or do anything else. All I'm doing is firing up the server, per the command above. This used to work perfectly on my server without causing massive server load, so something has changed, but I'm not sure what. My server is a managed VPS so I don't know if there is some kind of auto-update script that kicked in or what... but it's a problem. (Incidentally, even though the server load climbs like crazy, everything still works: after firing up Selenium, my server creates a screen with Xvfb so Firefox will be happy, then a PHP script talks to Selenium to do what it needs to do before shutting everything down. It takes a LONG time, and the load gets all the way up to 8 [!!!] before it is finished, which kills my web server and makes the main site horribly unresponsive... but it does get everything done.) Any suggestions for what is going on, why it's started doing this and/or, most importantly, how I can make Selenium not kill the server when it starts up... would be GREATLY appreciated!

  • On Windows how can I prevent login until a software package has been installed?

    - by Phil Hannent
    I have an MSI which is configured for machine level installation because it is a device driver. I can deploy it via Active Directory and Group Policy just fine. However on a newly booted machine a user can login before the installation has a chance to complete and I get an warning in the event log saying it couldn't complete and will be tried at next reboot. How can I make the login screen wait for the installation to be completed?

  • Can / should I prevent my domain controller doing forward lookups for remote users?

    - by markmnl
    I have a Windows Server 2003 server in the office. I VPN into the LAN remotely. My VPN has a virtual NIC with the Windows Server as the primary DNS since it is a domain controller. When connected to the VPN and I do a nslookup or simply browse the web my VPN's DNS (the office's Windows Server) provides the DNS answers - I beleive becuase it has DNS forwarders so queries it cant answer it forwards and then relays the answer. This is the desired behaviour for workstations in the office (they should query their domain controller first). However for remote VPN users this is not desirable - I do not want my remote office's server to answer DNS queries it is not the authority of (which happends to be 192.168.x.x). Is there any way I can configure this?

  • How can I prevent static when PC is plugged into an amplified speaker system?

    - by Kyle
    I've plugged a computer into an amp, using a 1/8 inch male extension cord, into a female adapter, that adapts into a male microphone 1/4 end. That being said, the amp sits at about half volume all the time because there are other things that play on it. (This issue is not flexible, nor is changing the amp) The problem is that now, even when I mute out the computer, you hear some static in the background. I was wondering some about some solutions (preferably multiple).

  • What can I do to prevent my user folder from being tampered with by malicious software?

    - by Tom Wijsman
    Let's assume some things: Back-ups do run every X minutes, yet the things I save should be permanent. There's a firewall and virus scanner in place, yet there happens to be a zero day attack on me. I am using Windows. (Although feel free to append Linux / OS X parts to your answer) Here is the problem Any software can change anything inside my user folder. Tampering with the files could cost me my life, whether it's accessing / modifying or wiping them. So, what I want to ask is: Is there a permission-based way to disallow programs from accessing my files in any way by default? Extending on the previous question, can I ensure certain programs can only access certain folders? Are there other less obtrusive ways than using Comodo? Or can I make Comodo less obtrusive? For example, the solution should be proof against (DO NOT RUN): del /F /S /Q %USERPROFILE%

  • How can I prevent OpenVPN from clobbering local route?

    - by ataylor
    I have a local network on 192.168.1.0 with netmask 255.255.255.0. When I connect to a VPN though OpenVPN (as a client), it pushes a route for 192.168.1.0 that clobbers the existing one, making my local network inaccessible. I don't to access anything on 192.168.1.0 on the remote machine; I'd like to just ignore it, while accepting the other routes that are pushed. My client is Ubuntu 10.10. How can I skip the one offending route?

  • Prevent important OS X process being swapped out, without code change?

    - by purplie
    I want hotkey-based utilities like Quicksilver or Zooom to respond immediately. But if they have been idle for a while, they (I guess) get swapped out, and respond slowly, sometimes not even responding to the first few keystrokes I wanted to send to them. How can I encourage such processes (i.e. chosen processes, not all processes system wide) to remain in active memory? Or, am I misunderstanding the problem?

  • How to prevent Ubuntu from combining networks on 2 NIC server?

    - by SolarPower
    I've got a Ubuntu Server 10.10 with 2 network interfaces with a cable plugged into both going to switches on completely different networks with different routers. One network is the 10.1.10.X network with a separate gateway/router - the server has an IP of 10.1.10.50 with the gateway IP of 10.1.10.1. The other interface is 10.2.10.X, IP 10.2.10.50, gateway 10.2.10.1. All my Mac machines are on the 10.2.10.X network, and all servers on the 10.1.10.X. The ONLY connection between the two is this machine. From a Mac in my office, I CANNOT ping any computer on the 10.1.10.X network except the Ubuntu machine I'm talking about. However, under the Shared column in Finder, I can see every server on the other network listed. That makes me believe that somehow this Ubuntu machine is letting certain requests span both networks, which is a security problem. Hope this is enough info.

  • What could prevent one Amazon EC2 instance from pinging another instance's Private IP?

    - by ks78
    I have multiple Amazon EC2 instances which need to communicate using private IPs. However, so far I've been unable to ping one instance's private IP from another instance. I can ping external addresses, such as their Elastic IPs and other sites (yahoo, google, etc), so it seems there's nothing wrong with the instances' network configuration. Also, they are all in the same zone, so that shouldn't be an issue. Does anyone have any idea what I could be doing wrong? Could this related to the Security Group settings?

  • How to prevent hard drive from spinning down Windows 7?

    - by JL.
    I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?

  • How can I prevent my volume from changing when initiating a Skype call?

    - by Daniel
    I already know about the option in Control Panel Sound Communications, so please don't bother pointing me there. I am using the Skype Modern UI app and whenever I start a call, it lowers the volume of anything else that I have active. How can I resolve this issue? Also, not sure if this is related, but any Modern UI music apps also lower their own volume when they are not in the foreground. This seems relevant: http://blogs.msdn.com/b/windowsappdev/archive/2012/08/23/media-playback-what-you-need-to-know-about-playing-media-to-make-your-app-shine-in-windows-8.aspx

  • How to prevent ssh git push to set file ownership?

    - by e-satis
    I have a remote bare git repository on an Ubuntu server, where the file are owned by the user my_project and the group my_project, with permissions set accordingly. All commiters are themself in the group my_project. When somebody commit then push from my Ubuntu laptop with the user my_user to the server via SSH, some files in the remote repository are created (updated?) so they now belong to the user and group my_user. Of course, when somebody else want to commit, he is now unable to do so because he doesn't have write permissions. I could set permission to 777 but it's not the best option. Is there any way I can solve this problem while keeping restricted write permissions.

  • How to prevent Microsoft Lync adding startup entry in Windows?

    - by Naresh
    Microsoft lync makes my laptop boot very slowly and if I disable it from startup, the laptop boots fine and quick. However the issue is, if I start lync again, it puts an entry to startup. So I end up disabling again and again before every boot. I try to put my laptop into sleep only as much possible, however there are many times I need to start up. So, please suggest how to do any of the following? How to remove a program from start up, programatically or a windows setting? How to disable Microsoft lync to stop putting an entry into startup?

  • Why did windows change the elevation requirements of my AutoHotKey script, and how can I prevent such in the future?

    - by monsto
    I was working on an AutoHotKey (AHK) script to create prefab mouse movements for a very simple model viewer. I worked on it for a good hour. I zipped the script, posted it to a forum, and thought "oh hey, I should add bla bla bla to the script". When I returned to the program, the AHK script would not work. I could see the mouse movements working in other programs (notepad, chrome, etc), but not where I had been working the previous hour. After several hours of throwing darts at the troubleshooting wall, I discovered that the fix was to set the AHK.exe to Run as Administrator. The question here are multiple Why did Windows 7, in all it's wisdom, suddenly decide that elevation was necessary in the middle of usage? Can these permission requirements somehow be reverted by, say, removing a key from the registry or something? How can this kind of Windows behaviour be avoided in the future?

  • Does stunnel prevent non ssl traffic to "the" specified port?

    - by user432024
    So say I have an arbitrary tcp port 12345 and it's non ssl and I want to put stunnel to secure traffic to it. When stunnel is in front of it does it mean that this port is now tls/ssl only? Or can you still connect to it unencrypted? Basically I want to make sure that this port can only be accessed through ssl/tls and stunel and no other way. Clarification I want to make sure only stunnel port is open. Which is answered in the comments that the unsecured port should be fire-walled but preferably bound to localhost.

  • Can I prevent tv-out from disconnecting when monitor sleeps?

    - by Damon
    I have my TV connected to my computer (windows 7) through an HDMI cable that also carries the sound. I like to put on music on my TV, but the problem is when my monitor goes to sleep back in my office, it switches off the hdmi connection completely and the audio goes back to my PC. I would like a way to stop this from happening without turning off sleep mode entirely. I have an ATi Radeon 5700

  • Is there a way to prevent output from backgrounded tasks from covering the command line in a shell?

    - by Chris Pick
    I would like to be able to run task(s) in the background of a shell and not have their output to stdout or stderr cover the command line at the bottom. Frequently I need to run other commands to interact with the background processes and would like to do so from the same shell without having to open up another terminal or using multiplexer to split the terminal like screen. Ideally there would be some setting that I just don't know about (I commonly use bash or ksh), but a new or different shell or a script would be fine by me. I'm open to any suggestions and appreciate any help, thanks.

  • How to prevent mod_proxy from rewriting redirects into absolute URLs?

    - by Yang
    I have: nginx (port 80) reverse-proxying to apache2 (port 88) reverse-proxying to a web app (port 5001). However, when the web app responds with a redirect like Location: /foo, apache2 rewrites this into Location: http://host.com:88/sub/foo, even though port 88 is publicly inaccessible. I'd like it to just redirect to the relative URL Location: /sub/foo. Any ideas? My apache config (using mod_proxy_http, mod_proxy_html, mod_substitute): <Location /notes/> Allow from all ProxyPass http://127.0.0.1:5001/ SetOutputFilter proxy-html ProxyPassReverse / ProxyHTMLURLMap / /notes/ RequestHeader unset Accept-Encoding AddOutputFilterByType SUBSTITUTE application/atom+xml Substitute "s|127.0.0.1:5001|host.com/notes|" </Location>

  • How do you prevent the dock from switching monitors in OSX Mavericks?

    - by Brad Dwyer
    In Mavericks, Apple introduced a "feature" where if you hover at the bottom of any screen the dock pops up on that screen. This is disrupting my workflow as I am constantly having the dock pop up when I don't want it to and then I have to go to another window and hover at the bottom for several seconds to get it to go away so I can click on what I was trying to in the first place. I don't want the dock to move; I want it to stay on the bottom of my right-most monitor like it always has. How can I adjust this in OSX Mavericks?
