Programming :: Detect Keypress Without Needing Return?
Oct 21, 2010I'm witting a piece of code that needs to read key presses. However I cannot use them as stream, but rather need discrete reads. The code is to simulate an io board interface. So When I press say "d" I need to read it in instantly, not wait for return. I've tried sdl, but no luck (I'm reading in a thread and it causes some problems) I'm using linux so can't use conio.h functions, I've tired gatch from cureses but this still waits for return.So in C/c++ is there a way I can read instant key presses.

Programming :: Hashing The Components Of An Tcp Session To Assign/locate The Session In A Hash Table Bucket?
Nov 10, 2010I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

Fedora Servers :: RDP As Console Session?
Aug 29, 2011I have RDP working fine on my machine, however when I am signed in locally to the machine, I get the "console" session, which is fine, but when I want to RDP from another machine, I am put into a separate session, instead of "taking over" the console session.Is there a way to do this, similar to how RDP works on a windows machine?I have tried running the mstsc /console command, but I still get stuck into a non-console session.

View 1 Replies View RelatedDebian :: Console Only Session - Hard Drive Malfunction
Jun 16, 2009My hard drive's file system has become totally mucked up. I had a few partitions on it, 0 is XP, 1 is vista, 2 is Debian, and 3 is the data. I know that it's this hard drive because when I disconnect it, any liveCD runs ok. After failing to boot puppy linux (liveCD), xp (bootmgr not found), debian (ended in kernal panic), I tried GPARTED. The xp and vista partitions are listed as existing, but they show a problem flag, gparted says they are corrupt, and they are not listed as having a start, end, or any data. However, the main data partition does list a start, end, size, and data space used.
I need to either format those or get into something that will let me access the data partition. Gparted either hangs on boot or doesn't recognise the mouse so I can't reformat the bad partitions. Are there any programs that will ignore the bad partitions and let me access the good ones? Any time I go into a linux distro it either ends up in kernel panic or the mouse doesn't respond. It's hard to explain. With GPARTED, sometimes it hangs at the third line, sometimes it fails at "mounting hard drives", and sometimes it makes it to the GUI but I can't use the mouse. Debian alternates between these as well.
If I keep trying it looks like I can boot, and it will recognise the partitions, but I can't use the mouse. I'm kind of familar with bash, is there a way to start up the terminal with no gui? If I could get a terminal up with a hotkey in the GUI or just start up from a terminal (no gui), I could type mv dev/sda3/ or whatnot. If I could get into a terminal of gparted I could format the bad parts of the drive to see if that would work. Otherwise it looks like I'm going to have to zero out the drive with the WD diag tool. The data isn't life or death, but it would save me some time.

Jun 4, 2011I have a question regarding runlevels, shutdown procedure and KDM. I am on a freshly installed Slackware64 13.37 multilib system. The default runlevel in /etc/inittab is set to 3: multiuser w/o X.
Now, I log in as root and issue the command:
Code:
As expected, KDM starts up, and I log in to KDE (or another WM/DE) as a normal users. When I am finished, I either issues
Code:
In Konsole or click on Shutdown in the KDE menu. The shutdown process is initiated, as expected, but then it stops, and a window alerts me, that there is a session open by user 'root'. If I click OK, the machine is finally shut down.
Now, if I interpret this correctly, the behaviour of Slackware64 13.37 has changed here, compared to 13.1. In previous versions, the root seesion was closed, when I changed the runlevel to 4 with the telinit command. Now, the session remains open, obviously.
My question is: Is this the correct behaviour, and isn't this a security whole? An unnoticed (!) open root session while I am surfing the web as an unprivileged user in KDE could be dangerous, I think...
Is it misconfiguration in my system, or is this the way it should be?

Programming :: Python And Curses : Unable To Getch() For A Curses.KEY Event

Ubuntu :: Run Fsck On Keypress During Boot?
Jan 4, 2011I am wondering if there is a way to manually trigger a file system check during boot by pressing/holding a key. Maybe there is already a keyboard shortcut built in to do this?I know that using tune2fs you can modify the number of boots (mounts) between file system checks, or even use "shutdown -rF" to reboot the system and force a file system checkAlso, I do not want to force the user to choose to run/skip the file system check during boot. For example, prompting the user with, "Do you want to run a file system check [y/n]?" each boot (or even each time the system thinks it should run a file system check),s not desirable

View 8 Replies View RelatedUbuntu :: Simulate Keypress Via Keyboard Shortcut?
Feb 21, 2011I have a G15v1. After going through hoops and loops to get it working only to discover that you only needed to install g15daemon through the Ubuntu Software Center, I found myself with one big problem. I migrated from windows just now, and there, I had my macro keys(the extra ones) bound to CTRL+W, CTRL+T and to a simulated mouse-wheel scroll so I could navigate the web more easily. How would I go about doing that? I figured, if I used the System->Preferences->Keyboard Shortcuts thingy and bound my key, in my case XF86Launch5, to a command similar to "simulate keypress CTRL+W"(I know it's totally wrong, just to give you an idea), I might be able to get it working again. Only problem is, I can't find anything like that. Any of you has any clue about it? I googled but I only find C++/Java/coding related results, which are not exactly what I need to do.

Ubuntu :: Grub2 Waits For Keypress After Failed Boot?
Jan 6, 2010Last week I installed minimal Ubuntu Karmic with XBMC live on my HTPC. I'm connecting to my fileserver thru a wireless interface and although that works like a charm most of the time, every once in a while the interface doesn't come up during boot and the PC 'hangs'.
I then press ctrl+alt+del and the pc reboots and the Grub2 boot menu appears, I suppose because the previous boot didn't go well. However, the boot menu doesn't have a timeout, I have to press <enter> to continue booting. My wireless USB-keyboard isn't working at that stage yet, so I'm unable to continue.
This is my /etc/default/grub
Code:
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash xbmc=autostart,nodiskmount,setvolume loglevel=0"
GRUB_CMDLINE_LINUX=""
How can I get it such that Grub always times out, even after a failed boot?

CentOS 5 :: Switch Between Full-screen VNC Instances With One Keypress?
Oct 9, 2010OS: Centos 5.4
VNC Viewer Free Edition 4.1.2 for X
Switching between two instances of VNC viewer in full-screen mode takes three key presses and two mouse clicks. How can the viewer be configured to pass a special key combination to the host operating system instead of the remote OS, so it's possible to switch between full-screen viewers in one key press?
e.g. With the default configuration, if I put the viewers in adjascent workspaces, then the sequence to switch is: F8 MouseClick Ctrl+Alt+Left F8 MouseClick If the key combination Ctrl+Alt+Left was passed to the host then it would be possible to switch workspaces (and therefore viewers) in one key press. When working on multiple remote machines, both physical and virtual, it's often necessary to switch between them frequently. I must switch over 100 times some days. Simplifying the key sequence would be both quicker and more intuitive.
General :: Execute A Program Based On A Keypress From A Specific USB Keyboard?
May 4, 2011I've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.
The button identifies as
Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.
I'd like to know if there's either
a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.
