  • Command Design Pattern

    - by pchajer
    After reading command design pattern, I have a couple of question - Why we are creating concrete command and receiver object on client. Can't this initialization on invoker class? I think client should create invoker and pass it's request to invoker. Invoker should take care of all the stuff. By doing this, We have less dependency on client. The design of class diagram is totally different from actual design.

    - by i.h4d35
    I've been trying to install either Arch Linux or Fedora 17 on VMWare Workstation (7.1.3). After I point to the right ISO image, I get the following error: Booting the kernel PANIC: early exception 0d rip:ffffffff81042dc4 error 0 cr2 0 I am trying to install it on a machine which has a 3rd generation i5 processor. After checking A VMWare panic early exception fix for ivy bridge i3, i5, i7, I tried to turn off the nosmep acpi. This is around, I get the same error but at a different address. Apparently, others have faced this issue before. Thanks in advance.

  • Can't install kernel-uek-headers for currently running kernel

  • Error: "failed to connect to wpa_supplicant - wpa_ctrl_open no such file or directory" using netcfg with wpa_supplicant

    - by user1576628
    I'm trying to set up netcfg so that I can finish installing Arch Linux (using the instructions from the Beginners' Guide and netcfg) and I passed over what was meant to be a short step. Open wifi-menu, select network, enter password. After multiple attempts, I decided to edit the profile manually, which yielded no improvement. Eventually I decided to use netfcg with the more familiar wpa_supplicant. My /etc/wpa_supplicant.conf file is as follows: network={ ssid="my_ssid" #psk="my_wireless_passcode" psk="my_wireless_passcode_hex" } (Replacing generic names with my actual ssid and psk.) And my /etc/network.d/wpa_suppl file reads: CONNECTION='wireless' DESCRIPTION='A wpa_supplicant configuration based wireless connection' INTERFACE='wlan0' SECURITY='wpa-config' WPA_CONF='/etc/wpa_supplicant.conf' IP='dhcp' My ssid is not hidden, wlan0 is the proper interface, and wpa_supplicant works fine on its own, but using netcfg wpa_suppl, it returns failed to connect to wpa_supplicant - wpa_ctrl_open no such file or directory about twelve times before finally telling me the authentication failed. What can I do to fix this?

  • Best distro for eee-pc [closed]

    - by a_m0d
    Possible Duplicate: A minimal Linux distribution for my ASUS EEE PC I am looking at buying an Asus eee PC and would like some input from the community on the different distros / OS's out there for it. I have heard that the Xandros distro that comes with the net-book isn't that great (lack of software, etc.), but I wonder what all the SuperUsers out there think. Please answer with one distro / OS per answer, and list (at least some of) the advantages and disadvantages of your choice. EDIT: To clarify, the version I am looking at is the 701 SSD, with the 8GB hard drive.

  • LightDM will not start after stopping it

    - by Sweeters
    I am running Ubuntu 11.10 "Oneiric Ocelot", and in trying to install the nvidia CUDA developer drivers I switched to a virtual terminal (Ctrl-Alt-F5) and stopped lightdm (installation required that no X server instance be running) through sudo service lightdm stop. Re-starting lightdm with sudo service lightdm start did not work: A couple of * Starting [...] lines where displayed, but the process hanged. (I do not remember at which point, but I think it was * Starting System V runlevel compatibility. I manually rebooted my laptop, and ever since booting seems to hang, usually around the * Starting anac(h)ronistic cron [OK] log line (not consistently at that point, though). From that point on, I seem to be able to interact with my system only through a tty session (Ctrl-Alt-F1). I've tried purging and reinstalling both lightdm and gdm, as well as selecting both as the default display managers (through sudo dpkg-reconfigure [lightdm / gdm] or by manually editing /etc/X11/default-display-manager) through both apt-get and aptitude (that shouldn't make a difference anyway) after updating the packages, but the problem persists. Some of the responses I'm getting are the following: After running sudo dpkg-reconfigure lightdm (but not ... gdm) I get the following message: dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_NAME missing dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_PACKAGE missing After trying sudo service lightdm start or sudo start lightdm I get to see the boot loading screen again but nothing changes. If I go back to the tty shell I see lightdm start/running, process <num> but ps -e | grep lightdm gives no output. After trying sudo service gdm start or sudo starg gdm I get the gdm start/running, process <num> message, and gdm-binary is supposedly an active process, but all that happens is that the screen blinks a couple of times and nothing else. Other candidate solutions that I'd found on the web included running startx but when I try that I get an error output [...] Fatal server error: no screens found [...]. Moreover, I made sure that lightdm-gtk-greeter is installed but that did not help either. Please excuse my not including complete outputs/logs; I am writing this post from another computer and it's hard to manually copy the complete logs. Also, I've seen several posts that had to do with similar problems, but either there was no fix, or the one suggested did not work for me. In closing: Please help! I very much hope to avoid re-installing Ubuntu from scratch! :) Alex @mosi I did not manage to fix the NVIDIA kernel driver as per your instructions.

  • How to configure wpa_supplicant on RHEL6?

    - by Yang Jy
    I am running a version of RHCE6 on my laptop. I uninstalled the default NetworkManager in order that I could configure the network all in the command line. The Ethernet part is okay, but I have problem bringing up the wireless interface. What I got is: Bringing up interface wlan0: Determining IP information for wlan0... failed; no link present. Check cable? I did exactly what this article says. I am not sure if it is because the article is obsolete or something else. Please help.

  • Running a small IPTV station

    - by nixterrimus
    I'm looking to run an iptv station for my dorm. I know I can serve multicast so that's not a problem. The station will serve out podcasts and other cc licensed content. The target endpoint is xbmc- a media center. So far I know that I need to serve an rtp stream over udp that's streaming an mpeg-4 avc main or high profile with aac ( or ac3 ?) audio. I've had some luck using vlc with vlm to stream but it seems limited. What are my other options?  Everything has to run on Linux- hopefully open source. How can I use playlists and not live streams? What are my software options?

  • Repair GRUB bootloader for multiboot system

    - by user1715324
    I have two hard disks – one a 1TB and the other a 250 GB. I installed the OSes in the following order: Windows 7 on the first hard disk (1 TB) After that Kubuntu 12.04 on a partition (/dev/sdb7) on the second hard disk (250 GB) The second drive also contains an NTFS partition. Now, kubuntu's bootloader was installed on the second hard drive's MBR (and successfully detected Windows 7). So, whenever I wanted to load Windows I used to select the first hard disk from the BIOS boot menu and the second hard disk whenever I wanted to load kubuntu. I know I could have set the second hard disk as the default drive, still I prefered this method. The problem started when I installed Linux Mint 13 on the second hard disk (/dev/sdb3) and overwrote kubuntu's original MBR. Now, the GRUB just detects Mint and Windows. The MBR on the 1 TB hard disk is untouched. Is there a way I can modify the MBR on the second hard disk now so that it will show kubuntu and Mint both?

  • How do I disable other monitors while running games in Wine?

    - by Michael Cheng
    My current setup is: * Dual GTS 250 video cards * 3 Monitors * Used nvidia-settings to run each monitor as a separate x session * This is all running on Linux Mint Debian Edition When running games (Starcraft II) in Wine via PlayOnLinux, I've found that the mouse does not get locked. I already tried various solutions littered across the web and none work so I'd rather just disable my other two monitors while playing. Does anyone know of a method where I can turn off my other two monitors (not my primary monitor) while running Wine and then turn then back on afterwards? I don't mind having to manually run a script before and after gaming. Thanks.

  • Ping isn't acting accurate?

    - by Earlz
    I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

  • Coloring The Z Shell[closed]

    - by Richard
    Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt. My .zshrc is Phil's Prompt. My .Xdefaults is: *background: #121212 !black xterm*color0: #353535 xterm*color8: #666666 !red xterm*color1: #AE4747 xterm*color9: #EE6363 !green xterm*color2: #556B2F xterm*color10: #9ACD32 !brown/yellow xterm*color3: #DAA520 xterm*color11: #FFC125 !blue xterm*color4: #6F99B4 xterm*color12: #7C96B0 !magenta xterm*color5: #8B7B8B xterm*color13: #D8BFD8 !cyan xterm*color6: #A7A15E xterm*color14: #F0E68C !white xterm*color7: #DDDDDD xterm*color15: #FFFFFF *foreground: #DDDDDD Help will be appreciated.

  • Socks5 proxy "Dante" leaves many child processes stuck in FIN_WAIT2 / CLOSE_WAIT state

    - by Asad R.
    I'm running dante v1.2.1 as a SOCKS proxy server. The proxy works fine but at the end of the day there are around 40-50 or more child processes of sockd running even though there are no active connections. lsof shows that the child processes all have sockets in the CLOSE_WAIT and FIN_WAIT2 state. These child processes stay in this state unless I manually killall/restart the daemon. I'm running Gentoo Linux on a 2.6.24-23-xen kernel. I recently upgraded from dante v1.1.19-r4 which was giving me the exact same problem. Is this a configuration issue with Dante, my system, or is it a coding issue in the dante code?

  • Munin "Available entropy" when using address space layout randomization

    - by clawspoon
    Having just configured Munin for statistics logging on my gentoo server (hardened profile), I am noticing that my "Available entropy" is consitently in the 200-300 range. This seems way to low, so I checked it manually using the command $ cat /proc/sys/kernel/random/entropy_avail 3544 Odd. Consistently very low values in Munin and practically filled up when checking manually. After thinking about the problem for a while I came to the conclusion that the problem is probably that I'm using Adress Space Layout Randomization which is using the entropy when running commands/programs. Since Munin runs a whole slew of programs all the entropy is used up, and Munin then measures how much entropy there is, resulting in the low values. Does anyone have any experience with this? How can this be avoided?

  • Input not supported message when monitor is powered off then back on

    - by Jason Down
    I've been getting a message on my monitor where "Input not supported" is floating around. This only happens when I manually turn the monitor off and then later turn it back on. Leaving the monitor on and allowing it to go to the screen saver doesn't seem to cause the issue (but I prefer to turn the monitor off if I'm going to be away from the computer for any length of time). Any ideas what might cause this, only when the monitor is turned off manually? Specs: Acer X203w mointor Radeon 9600 Pro Video card Linux Mint 8 Resolution 1680 x 1050 (16:10 - Preferred native resolution for the monitor) Refresh Rate 60hz Here is what is in my xorg.conf file: Section "Device" Identifier "Radeon 9600" Driver "ati" BusID "PCI:1:0:0" Option "XAANoOffscreenPixmaps" Option "AccelMethod" "XAA" EndSection Section "Screen" Identifier "Default Screen" Device "Radeon 9600" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1680x1050" "1440x900" "1024x768" EndSubSection EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" EndSection

  • Oracle Keeps Growing Partner Certifications with Addition of McAfee

    - by Ted Davis
    Viruses stink. Whether it’s the common cold virus, Goatpox virus – yes it exists -- or a computer virus, you name it, viruses stink. When it comes to our computer server infrastructure we all want to make sure our servers are secure from any malware out there. Additionally, installation of anti-virus software is a requirement by many governments and for many enterprises both large and small. Because of the growth of Oracle Linux in their customer base, McAfee recently certified their “McAfee VirusScan Enterprise for Linux” on Oracle Linux.  It delivers always-on, real-time anti-virus protection for Linux environments. Its unique, Linux-based on-access scanner constantly monitors the system for potential attacks. While there have been few viruses found on Linux, you can now feel secure running Oracle Linux in your infrastructure with McAfee on top. We are happy to introduce McAfee into the Oracle Linux family of certified applications.

  • buggy mouse click after a while

    - by sputnick
    The cursor of my mouse is moving as well on my twin view, but after a WHILE, or if I start kde with runlevels (I don't know why, but startx works better) I can't click anything. I have had replaced the mouse with another one, but it's the same problem, so it's not a hardware problem. The problem occurs both with gnome and kde. My config : PC Dell Optiplex 780 archlinux x86_64 (up to date) xf86-input-evdev 2.6.0-4 xorg-server 1.11.2-2 kernel linux-3.1.1-1-ARCH My Xorg log doesn't contains "EE" string for errors. Any clue ?

  • Why is systemd not setting my system time?

    - by Alex Chamberlain
    I'm running Arch Linux. Recently, when I turn on my PC, the system time is set to 1:00 1 January 1970 - presumably the 1:00 o'clock is from the timezone shift. Does anyone have any ideas why systemd isn't setting my system time correctly? Some useful output (I think)... [root@alex-desktop network.d]# timedatectl status Local time: Sun 2013-06-09 16:33:04 BST Universal time: Sun 2013-06-09 15:33:04 UTC RTC time: Sun 2013-06-09 15:18:50 Timezone: Europe/London (BST, +0100) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: yes Last DST change: DST began at Sun 2013-03-31 00:59:59 GMT Sun 2013-03-31 02:00:00 BST Next DST change: DST ends (the clock jumps one hour backwards) at Sun 2013-10-27 01:59:59 BST Sun 2013-10-27 01:00:00 GMT

  • Gnuplot with octave produces only entirely black bar diagrams

    - by Lambda Dusk
    My problem is the following: On my system (Linux Mint 14), the normal octave and gnuplot packages only produce completely black bar diagrams: I have tried to change the colours in any way I could imagine, but no avail: bar(xbin, yy, 'barwidth', 1, 'facecolor', 'r', 'edgecolor', 'b'); xlabel('x_i'); ylabel('p_i'); print -deps bars.eps However, when I plot the graph with the command graphics_toolkit fltk; It looks fine - but fltk doesn't either understand umlauts or LaTeX-style formula notation like p_i (necessary for captions and labels). Maybe I haven't configured something correctly. I just installed octave from the repos and thought it would work. Anyone can help?

Sending select for 192.168.10.198... Lease of 192.168.10.198 obtained, lease time 691200 but when i check with ifconfig i can see that it didn't assign the ip address to eth0. anyone have an idea why udhcpc didn't assign the ip ? Thanx
