  • Where does Tomcat cache my taglib .jar files?

    - by NogginTheNog
    I'm deploying a .jar file to a tomcat instance (we're running 6.0.18 on Redhat linux) and according to the log output the old .jar is still being used. I've restarted everthing I can think of, have deleted the work directory etc.etc. but to no avail. I'm no tomcat expert, so here's my question: where should I look for to ascertain if tomcat is using a cached jar and how should I prevent it from doing so?

  • Having Textmate warn me when writing to a file that was modified since Textmate last read it

    - by emm
    Scenario: I open a file, I edit it. After I began editing, the file is modified by another program. Finally, I save the file. In that case, Vim would provide that helpful warning: WARNING: The file has been changed since reading it Do you really want to write to it (y/n)? But Textmate will overwrite the file silently, which can result in unpleasant data loss (in my case, a de facto revert on Git). How can I prevent that?

  • "Safely Remove Hardware" icon keeps reverting to "Only show notifications"

    - by Dan Parsonson
    I have the 'Safely Remove Hardware' tray icon set to 'Show icon and notifications' to save a mouse click when removing a USB device but every few weeks the setting reverts to 'Only show notifications'. Does anyone know what causes this and/or how I can prevent it? I'm using Windows 7 SP1 64bit with a fairly bare installation (the machine hosts a set of virtual machines that I use to do my work). Thanks!

  • When disabling the firewire-driver in Windows will this too disable firewire connected through a PCMCIA device?

    - by Christoffer
    The broader overarching question (not seeking an answer to this, but wanted to provide context) is how do I ensure that laptops running Microsoft Windows 7 and exposing DMA-ports (eg. firewire) are disabled once the operating system have loaded. Preventing the Firewire-driver from loading once Windows have booted works as expected, but I've been unable to confirm whether this too will disable a Firewire-port exposed through a PCMCIA-card. My question is hence whether disabling the Firewire-driver will also prevent a Firewire-port exposed through a PCMCIA from functioning?

  • How to leave the teamviewer window with Alt+Tab

    - by rubo77
    I use Teamviewer on Ubuntu (Not sure if the problem is the same on Windows). Whenever I use Alt+TAB to change the focussed window on my computer to another window while the remote window has focus the remote window catches the Alt keydown event but not the Alt release event! So when I get back to the remote Teamviewer window the remote computer still has the Alt Key stuck pressed. How can I prevent that the Alt-key gets stuck on the remote computer?

  • iptables : how to correctly allow incoming and outgoing traffic for certain ports?

    - by Rubytastic
    Im trying to get incoming and outgoing traffic to be enabled on specific ports, because I block everything at the end of the iptables rules. INPUT and FORWARD reject. What would be the appropiate way to open certain ports for all traffic incoming and outgoing?

  • Preventing 'Reply-All' to Exchange Distribution Groups

    - by Larold
    This is another question in a short series regarding a challenging Exchange project my co-workers have been asked to implement. (I'm helping even though I'm primarily a Unix guy because I volunteered to learn powershell and implement as much of the project in code as I could.) Background: We have been asked to create many distribution groups, say about 500+. These groups will contain two types of members. (Apologies if I get these terms wrong.) One type will be internal AD users, and the other type will be external users that I create Mail Contact entries for. We have been asked to make it so that a "Reply All" is not possible to any messages sent to these groups. I don't believe that is 100% possible to enforce for the following reasons. My question is - is my following reasoning sound? If not, please feel free to educate me on if / how things can properly be implemeneted. Thanks! My reasoning on why it's impossible to prevent 100% of potential reply-all actions: An interal AD user could put the DL in their To: field. They then click the '+' to expand the group. The group contains two external mail contacts. The message is sent to everyone, including those external contacts. External user #1 decides to reply-all, and his mail goes to, at least, external user #2, which wouldn't even involve our Exchange mail relays. An internal AD user could place the DL in their Outlook To: field, then click the '+' button to expand the DL. They then fire off an email to everyone that was in the group. (But the individual addresses are listed in the 'To:' field.) Because we now have a message sent to multiple recipients in the To: field, the addresses have been "exposed", and anyone is free to reply-all, and the messages just get sent to everyone in the To: field. Even if we try to set a Reply-To: field for all of these DLs, external mail clients are not obligated to abide by it, or force users to abide by it. Are my two points above valid? (I admit, they are somewhat similar.) Am I correct to tell our leadership "It is not possible to prevent 100% of the cases where someone will want to Reply-All to these groups UNLESS we train the users sending emails to these groups that the Bcc: field is to be used at all times." I am dying for any insight or parts of the equation I'm not seeing clearly. Thank you!!!

  • How to protect myself from promiscuous mode?

    - by Rivari
    I have read that some network adapters can switch to promiscuous mode and get all the packets sent by my router. We have multiple computers here connected to the same router. They all have the WEP key for authentification. So basicaly, this means that anyone of them, using the promiscuous mode, can see all the packets destined to others computers? That's frightening. How can I prevent this?

  • How to reliably keep an SSH tunnel open?

    - by Peltier
    I use an SSH tunnel from work to go around various idotic firewalls (it's ok with my boss :)). The problem is, after a while the ssh connection usually hangs, and the tunnel is broken. If I could at least monitor the tunnel automatically, I could restart the tunnel when it hangs, but I haven't even figured a way of doing that. Bonus points for the one who can tell me how to prevent my ssh connection from hanging, of course!

  • Why is the Windows UI responds slowly after being idle for a long time?

    - by John Isaiah Carmona
    I open these applications in my desktop computer: Visual Studio 2010 Professional IBM Lotus Notes Google Chrome And when it is idle for an hour and I restore the windows, the user interface responds very slowly. My computer auto-lock itself after being idle for 5 minutes. I also minimize the applications using a docklet (RocketDock). Why is it slowing down and how can I prevent it from slowing? My OS is Windows XP Professional SP3, Pentum(R) Dual Core @ 2.80 GHz, 1.99 GB of RAM.

  • Disable Device Stage Capability

    - by coelhudo
    Is it possible to prevent or disable autorun/autoplay/device-stage by modifying regedit? Because of some constraints, I cannot disable by Control Panel options. I found some related questions here, for example, and some solutions provided by Microsoft, mainly involving this key on regedit: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\NoDriveTypeAutorun But none of these solutions worked, neither after rebooting. Is there any other key or value that controls this kind of property?

  • Restricting Window Maximization Size

    - by sdasdadas
    I am currently running Conky to display some text on my background on the far right of the screen. The window is probably 200 pixels wide. Is it possible that when I maximize a window, there is some setting to prevent the window from completely maximizing? I have been manually adjusting the window size up until now. Eg. My resolution is 1024 x 800 but when I maximize any window it should only maximize up to 824 x 800... Thanks!

  • Question about RewriteRule and HTTP_HOST server variable

    - by SeancoJr
    In evaluating a rewrite rule that redirects to a specific URL and say the rewrite condition is met, would it be possible to use HTTP_HOST as part of the URL to be redirected to? Example in question: RewriteRule .*\.(jpg|jpe?g|gif|png|bmp)$ http://%{HTTP_HOST}/no-leech.jpg [R,NC] The motive behind this question is a desire to create a single htaccess file that would match against an addon domain (on a shared hosting account) and an infinite amount of subdomains below it to prevent hotlinking of images.

  • Can't Move Windows to 2nd Monitor without Left Mouse and Cntl Key

    - by John C
    I have 2 very frustrating problems that maybe someone can help me with: I have 2 monitors (different sizes and resolutions) setup with the "Extended" monitor Win7 setup. My problem is this = I can not "move" a window from my Primary Monitor (larger and higher resolution on right side in front of me) to my Secondary 2nd monitor (smaller and lower resolution) with just selecting the title bar with the left mouse button and dragging it to the left. Windows 7 "snaps" it back to the left Primary Monitor when the window is physically in the 2nd window area as I'm holding the left mouse button. I can prevent this problem - by holding down the Cntl Key with the Left Mouse button, but this is extremely annoying to me. Also I typically "lose" focus if I try typing input on the 2nd monitor. Typing is erratic with regard to keystroke accuracy from my keyboard translated into input on the 2nd screen. No problem with typing input on the primary left monitor. I find this extremely annoying in Windows 7 and turning off the "snap" feature via the Control panel does NOT work for me. Win7 stubbornly refuses to move my selected window to my 2nd monitor without me "forcing" Win7 to do this with the Cntrl Key. Please tell me this is not a Win7 feature. Also on my system - Windows Key + Shift, Left arrow Key (pressed together) or the same combo with The Right arrow Key - don't do anything whatsoever. Widows Key with "+" however does maximize current window across both monitors, and I can "restore" it with Windows Key and "-" back to original monitor and size. I have tried various solutions including changing the resolutions of one or both of my monitors and sometimes "temporarily helps" but reverts back to the problem. Also if I swap the logical (not physical) layout so that I tell Win7 the monitors are setup in a reserved situation (Large monitor on the left, and small on the right) - this also sometimes helps for awhile - and is very strange and awkward to work with "backwards". But all of these solutions stop working. The only solution that consistently works for "moving" the screens is to hold the Cntrl Key down as I'm moving window with the left mouse selected on the title bar. Even that however, doesn't prevent the loss of typing focus for me on the 2nd monitor - while at the same time the typing on the 1st monitor is fine. Any help on moving my window screens from one monitor on my 2nd monitor without having to press the Cntrl key while holding down my left mouse button with be appreciated. Also any help on gaining typing "focus" into my 2nd screen with be helpful too. Thanks - John

  • [Disallow: /index.php] seems to block /my-beautiful-sef-url-123

    Hello I have robots.txt that looks like this: User-agent: * Disallow: /system/ Disallow: /admin/ Disallow: /index.php The obvious goal has been to prevent all the ugly URLs from being indexed, as they all begin with "/index.php". But for some reason all URLs like /my-beautiful-sef-url-123 are listed under Crawl errors in Google Webmaster Tools with "URL restricted by robots.txt". (When I test such URL it yields Allowed for both Googlebot and Googlebot-Mobile.) Can anyone help please?

  • Suppress "running out of disk space" Message (per drive) on Windows Server 2003

    - by Shoeless
    We have a database server with separate drives for OS, various data files and the transaction log. Our transaction log spills over onto other volumes as well- this is expected behavior. The problem is that we are constantly getting popups that our transaction log drive is out of space (and that I can free space by deleting old or unnecessary files). Is there some way to prevent this message from popping up for this particular drive?

  • How to check if windows has automatic updates waiting from the command line?

    - by Lee
    If a Windows server (2k3/2k8) is set to "download but not install" updates, is there a way to check from the command line.. perhaps a log file or something I can check with powershell, to see if there are any updates actually waiting to be installed? I'm trying to prevent having to manually log on to each server to check, even though they want the "trigger" pulled manually. We have an automation system in place I can use (CA Autosys) - just not sure what to have it look for.

  • Feasible to use a laptop as a Digital Media Receiver/Extender?

    - by philosaur
    Since the price of many dedicated hardware Digital Media Extenders is only slightly lower than that of a cheap laptop, is there any reason you couldn't use a laptop as a Digital Media Extender? I'm looking for specific reasons that might make this unworkable. For instance, would the small screen/low-power video card of the laptop prevent the movie from playing well on the TV?
