  • Swap implication in Linux and way to increase it

    - by vimalnath
    I used top command to print this on Linux box: [root@localhost ~]# top top - 23:38:38 up 361 days, 12:16, 2 users, load average: 0.09, 0.06, 0.01 Tasks: 129 total, 2 running, 126 sleeping, 1 stopped, 0 zombie Cpu(s): 0.0% us, 0.2% sy, 0.0% ni, 96.5% id, 3.4% wa, 0.0% hi, 0.0% si Mem: 2074712k total, 1996948k used, 77764k free, 16632k buffers Swap: 1052248k total, 1052248k used, 0k free, 331540k cached I am not sure what Swap:0k free means in the last line. Is this normal behavior for a linux box to have value of 0 Thanks

  • VNC connection via SSH proxy machine

    - by pufferfish
    I would like to make a VNC connection from home to a Windows machine at work. The Windows machine is not accessible from the outside, but there is a Linux box that does have port 22 open, so it would seem that this can be done. I suspect it's just a command that "forwards" connections to port 22 on the Linux machine to the Windows machine? Just can't find an example that does exactly this though Thanks in advance!

  • How can I tell which "explorer.exe" process is the main one?

    - by HodofHod
    I have a batch file that changes a few registry files, and then restarts explorer.exe so that they take effect. I'm using the command taskkill /f /im explorer.exe and then explorer.exe which of course kills all the explorer.exe processes, including the explorer windows I have open. Obviously, I am using the option to Launch folder windows in a separate process. Is there any way I can determine which instance of explorer.exe is the main one, and just kill that?

  • How to display hidden Mac OS programs?

    - by LikeToCode
    Every time I minimize an application on my new MacBook, it minimizes, but when I switch to it, all i see is a menu on top saying that I am currently using that program, but it's still hidden. There is no menu command to "unhide" it, only to hide it. Is there a way to unhide it? Is there is a way to unhide it by default when I switch to the app?

  • How to avoid keyboard layout automatically changing on windows

    - by andrecarlucci
    I have two input languages in my language bar (windows xp). The problem is that windows likes changing between them without any intervention. That's really annoying! I know about the shortcuts and already turned off Word language detection, but the problem is everywhere (specially command prompt). I use both languages and I want to change between them only manually. How to turn off this automatic change?

  • Automake thumbnail

    - by Webmaster
    What I need to do is a program that given (as a command line argument) a directory with more directoreies inside, and 4 Pics inside of each dir, the program makes a thumbnail of the 4 files and glues them together (2 rows, 2 columns) and renames that image to the name of the directory. I think it could be done with a combination of a program and shell scripting (I'm experienced in M$, but new to linux). Some real examples would be great. Thanx in advance

  • I wanna save some terminal commands in a file

    - by Jakob Abfalter
    I am using Opensuse 12.3 What I wanna do is, create a link on my desktop for some specific terminal commandos. The backround is, that I do some backup via rsync and don`t wanna type the commandos everytime new. I also dont wanna use a cronjob, since my computer isnt running everytime. Perfect would be some desktop icons, which on clicking execute the command(s). Could somebody tell me how to do this?
