• Calculating Utilization in a Stop-And-Wait Protocol

  - by AlanTuring

  So theres this question in my book and it doesn't state exactly how to go about actually calculating utilization anywhere, and i'm not being able to find any substantial information regarding everything i need to solve this question.(My mid term is next week). Anyway, here's the question: The distance from earth to a distant planet is approximately 9 × 10^10 m. What is the channel utilization if a stop-and-wait protocol is used for frame transmission on a 64 Mbps point-to-point link? Assume that the frame size is 32 KB and the speed of light is 3 × 10^8 m/s. Suppose a sliding window protocol is used instead. For what send window size will the link utilization be 100%? You may ignore the protocol processing times at the sender and the receiver. thanks to anyone who has any idea.

• Ubuntu Upstart script hangs on start and stop

  - by sbwoodside

  I have an upstart script that will start a custom jetty server. When I do sudo start [myservice] nothing happens. Subsequently, sudo status [myservice] show it as: [myservice] start/killed, process 3586. Here's the script in /etc/init/[myservice].conf: description "[description]" author "[my name and email]" start on runlevel [2345] stop on runlevel [016] respawn expect fork script sudo -u www-data /path/to/grafserv-start.sh >> /tmp/upstart.log 2>&1 end-script And here is grafserv-start.sh: #!/bin/bash /usr/bin/java -Djetty.port=3070 -jar /path/to/grafserv/trunk/start.jar echo "Done starting GrafServ" I've tried redirecting the output of the script command to a tmp logfile, but that file is never created. When I start it, I just get a hang, until I ^C. Also, I tried running it with strace but that gave me a lot of stuff about sockets.

• Trackpad and battery on stop working at same time

  - by Alex Krycek

  Gateway E-475M G Windows 7 Professional SP1 Synaptics TouchPad 15.2.20.0 Microsoft ACPI-Compliant Control Method Battery 6.1.7600.16385 It seems that when my battery stops working correctly, my touchpad will also act erratically. Specifically, the computer will charge for a few seconds, then stop charging for another few seconds. This will continue for some time. But if I close the lid, the charging LED will stay lit. As for the touchpad, it'll click or highlight things at random when I can get it to move. As a test, I stopped charging my computer. Now it seems my touchpad is working fine. I've tried to reinstall both the battery and touchpad drivers. I've also started the computer in safe mode, but that didn't help either. Edit: I've now tried booting my computer with an Ubuntu live cd, and the charging problem persists. So, it now seems my computer can only charge continuously as long as it's turned off or sleeping.

• Apache 2.2.16 + PHP 5.2.14 sometimes causes Apache to not stop properly

  - by ZiggyTheHamster

  Sometimes, Apache decides not to shut down nicely. killall apache2 or kill -9 (apache2 PID here) shuts it down so that it can actually start back up without the port being in use. Other posts seem to indicate that PHP 5.2 might have issues hanging up Apache. I'm using the worker MPM on an x86_64 Gentoo Linux system if that helps. Any other things I should consider hanging up Apache besides PHP? Should I be stopping Apache with /etc/init.d/apache2 gracefulstop instead of /etc/init.d/apache2 stop?

• how to stop outgoing email spam

  - by James

  running an email system using roundcube, with about 200 people using it. 99% of them do as they are told and only email clients they have already spoken to, however 1% of them decide to bulk spam bcc emails, which then tripped an aol filter and almost got us banned from our host. I have disabled the guys account but I am worried about something similar happening in the future, what would be the best way to stop this? I read that if aol recieve 3 emails within 60 seconds from the same ip address then its an instant ban, so i am guessing with the big companies like google, their email accounts must have different ip addresses? and if so is there any way to implement a similar feature? Also i have spam assasin enabled, in this case what would be the best configuration for it?

• Stop VLC player from saving effects & filter settings

  - by bocamax

  VLC Player v1.1.11 Windows 7 Ultimate VLC player launches each new video with setting I used once to brighten a dark video. On a second computer, VLC player opens all videos rotated 270 which was a feature I used once. I now have to manually uncheck Image adjust on one computer & uncheck Transform on another for each video to have it play without these custom settings. I've custom mapped VLC Hotkeys that I use extensively. As a result, I do not want to "reset preferences" and lose my Hotkey mapping. VLC Tools Settings Video Effects Basic Image Adjust (Brightness, Contrast, etc.) VLC Tools Settings Video Effects Basic Transform (Rotate 90, 180, 270) Is there a setting I'm not finding to stop VLC from applying a one time adjustment to all videos?

• How to stop blanking screen although I am active on Ubuntu Karmic on old IBM Laptop

  - by Glen S. Dalton

  How to stop blanking screen although I am active on Ubuntu Karmic on old IBM Laptop 600E? After some time of working on the machine the screen goes blank. When I hit ESC on the built-in keyboard (not on the attached USB keyboard where I work) it comes back and everything works fine until the next screen-blanking. I suspect it is some power management issue. When I use an old keyboard that has a ps2 connector it does not happen. So my guess is that the usb keyboard does not update the power management timer that detects when the session was last used? I am using fluxbox window manager. I do not want to disable power management because it is nice that the fan only works at the necessary speed (the fan spped is regulated which I can hear) But I could disable power management for testing purposes.

• STOP: c000021a {Fatal System Error} The initial session process or system process terminated unexpectedly

  - by christof

  I'm encountering such an error after expanding disk space on a virtual machine using Hyper-V. STOP: c000021a {Fatal System Error} The initial session process or system process terminated unexpectedly with a status of (0x00000000) (0xc000012d 0x001003f0).

• Stop RAID 5 from Initializing

  - by Antz

  Hi, I am trying to follow Ictinike's guide on Recovering Intel RAID "Non-Member Disk" Error found here, Ictinike's RAID recovery Guide I have recreated my RAID array as per the instructions. However my RAID array status is then automatically set to: INITIALIZE When I boot back into my Windows XP desktop, the Intel Matrix Storage Utility begins to "Initialize" my drives. This is a long slow process that will take about 20 hours. I suspect all my data will be lost. I have gone back into my bios and disabled my RAID controller to prevent any further initialization and data loss. I have read that initialization will cause data loss. I've also read somewhere that it won't. I am not so confident in the latter. Is there anyway to stop this initialization process so I can continue to follow the steps in the recovery guide? Some system specs: ABIT IP35 Pro Motherboard ICH9R on board RAID controller

• Navigation keys on numeric keypad randomly stop working

  - by Tom Hughes

  Shortly after a restart, the arrow and navigation (Home, End...) keys on my numeric keypad will randomly stop working, and -- regardless of the state of the NumLock -- return only numbers. I notice this the most in browser applications (like this edit box) but the same effect is true on the command line and in desktop applications like Word. I swapped keyboards and now use a Microsoft keyboard (both are USB keyboards) but the same behavior persists. I also tried a clean boot to clean out startup programs but this made no difference. The separate arrow keys and navigation keys between the QWERTY keys and the numeric keypad work fine, but my strong preference (dating back to DOS and MS Flight Simulator) is to use the navigation keys in the numeric keypad.

• Windows XP Pro SP3 stop error code 0x000000F4

  - by Andrew Ford

  I have a system running Windows XP Pro SP3. My wife is the primary user of this system, and the last several days in a row, when she tries to log in to the system it gives her a BSOD with the stop error code 0x000000F4. The rest of the error codes change every time she tries to log on, but that one seems to stay constant. The error it gives me is: A process or thread crucial to system operation has unexpectedly exited or been terminated. The machine will also get stuck in a boot loop, where it keeps giving me the screen saying that windows did not start successfully, and to choose how to start windows. I have tried Safe Mode, Last known Good Config, and Normally, and all have resulted in either a return to the boot loop, or BSOD. What might this mean? How can I fix it, without doing a clean install?

• How to stop a Linux LVM volume group?

  - by thkala

  I am currently dealing with a multiple disk failure on a Linux LVM Volume Group that is backed up by a RAID-5 md device. One disk has been taken out completely and another one is showing a limited number of corrupt sectors, due to what seems to have been a misbehaving power supply. The problem is that once an I/O error hits, md takes the array down, since it does not have enough devices for it to be operational. Where md the only one involved, I could mdadm --stop the array and then recreate it to get all devices active again. Unfortunately, the array is a PV in an LVM volume group and I cannot seem to get the kernel to release it. vgchange -an does not seem to do anything, bar spew out a couple of I/O errors. I am obviously missing something, but how in the name of -insert-favorite-deity- do I get LVM to release the underlying PV without rebooting the server?

• arrow keys stop working to scroll pages

  - by Delirium tremens

  Sometimes, the arrow keys stop working to scroll pages. Sometimes, in Firefox - Tools - Options - Advanced - Accessibility - General, the first checkbox, about using arrow keys to scroll pages, appears checked and some other times, unchecked. When it's unchecked, I check it. When it's checked, I keep it checked. In both times, I click OK. Then, the arrow keys restart working to scroll pages. I'm having to do it all the time. What should I do?

• BSOD STOP 0x0000007B on windows 7

  - by Kartik Anand

  I have windows 7 with Ubuntu installed(Wubi installer). I didn't shut down my computer properly I guess because of which now I am getting the following BSOD STOP Error: 0x0000007B (0x80786B58 0xC0000034 0x00000000 0x00000000) But I am able to boot into Ubuntu without any problems. Now I've ran startup recovery about 3-4 times, tried system restore but nothing changes. I even ran CHKDSK /r /f from recovery console. I've not tried Fixmbr or Fixboot because I am afraid Ubuntu won't be able to boot then. Has anyone ever even able to get through this error?

• Stop jucheck from running

  - by Ken

  I've installed Java on Windows Vista, and every day I get a Vista security warning asking me if I want to run "jucheck". Apparently this is the Java automatic updater. Well, I don't want it to run on its own, ever. I cancel it, and quit it. I right-click on the taskbar and unclick "Check for Updates Automatically", and then click "Never Check", and "Apply". And yet, it never remembers this setting. If I come back to the "Java Control Panel" right after clicking "OK", the very same box is checked again, all on its own. Is there some way to kill jucheck once and for all? If I simply delete jucheck.exe, will Java (other than the automatic check) still work, and will manual updates still work, and will it stop even trying to update every morning?

• Stop windows-7 explorer taskbar icon changing for different locations

  - by Timothy Kane

  If I open an instance of Windows Explorer, a button appears on the taskbar; its icon matches the icon of current location in Explorer. E.g. If I've clicked on a drive (e.g. C:) then the taskbar icon changes to the drive icon. If I select the Pictures Library location, the taskbar icon changes to a little picture symbol. How can I stop this behaviour, so that the taskbar icon always shows the same icon, regardless of where I've clicked in Explorer?

• How do I stop CRM from asking for admin credentials when printing report

  - by Ac0ua

  Problem: When printing a report in CRM, I am asked by the UAC for admin credentials. There is a long URL: https://(crm_hostname)/reserved.ReportViewerWebcontrol.axd?ReportSession=(ID)ControlID=(ID)Culture=1333&UICulture=1033&ReportStack=1&OpType=PrintCab Info: There are three users that have the issue laied out here. They are not admins of any kind. It looks like it is asking for permission to allow SQL Server Reporting Services 2008 to run. When I put my credentials in, it just brings up the Print dialog box (this is fine, just stop asking for credentials). I know this might sound silly but I downloaded and installed "SQL Server Reporting Services 2008" hopping my credentials would give permission right from the beginning. Giving the users local admin, I was told is not an option. Note: I did post this on community (dot) dynamics (dot) com but, they are not a very active website. Thanks for any help even if it just points me in the right direction!

• Stop Munin messages from /var/log/syslog

  - by Sparsh Gupta

  Hello I am using munin on a system which is adding a log entry in syslog everytime the munin-node cron job executes. It is not an issue but it sometimes makes other errors spotting difficult. There are entries like Feb 28 07:05:01 li235-57 CRON[2634]: (root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then /etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then /etc/munin/plugins/apt update 7200 12 >/dev/null; fi) every 5 minutes and I was wondering how can I stop the messages going into syslog. For munin specific errors I anyways have to keep an eye on /var/log/munin/* Thanks Sparsh

• Does SMTP greylisting a) stop much spam and b) stop much legitimate mail?

  - by Whisk

  I've just set up an SMTP server on a relatively little used domain using Postfix and enabled greylisting with SQLGrey. So far it seems to be working OK, and while there's the slight irritation of delays to emails from new senders, I can see from the logs that it's deterring a number of spam messages. In your experience does greylisting effectively stop much spam? Is it a useful addition to e.g. SpamAssassin or is adding it on top overkill/unnecessary? If I were to roll this out to heavier use domains (perhaps with more demanding users) would you anticipate a significant portion of poorly configured mail servers that would end up bouncing or losing messages?

• How to stop ethernet interface in bridge configuration from obtaining IP address via DHCP

  - by user71061

  Hi! I'm trying to configure openvpn in bridging configuration. First step of doing this requires creating bridge interface (br0), bridging together physical ethernet interface (eth0) and logical tap0 interface. This can be done with simple script but I want to use less popular approach, configuring bridge interface entirely via /etc/network/interfaces file (on Debian linux). So I have removed all eth0 definitions form /etc/network/interfaces and replaced if with following br0 definition: auto br0 iface br0 inet static pre-up openvpn --mktun --dev tap0 address 10.0.0.1 netmask 255.255.255.0 bridge_ports eth0 tap0 post-down openvpn --rmtun --dev tap0 This works as I expected, but there is only one problem: interface eth0 is part of bridge interface br0 AND it also receive it's own IP address from my DHCP server (located on same LAN where eth0 is connected). My questions is: how to stop eth0 interface from obtaining it's own IP address? (It should only be part of br0 bridge).

• OS2/Warp - Remotely Stop and Restart a Program

  - by Justin S

  Our current phone system runs off of a legacy OS2/Warp box. Periodically we have to log into the machine and restart OS2RSD.exe and then start it again and the phone system starts working again. The problem is we have to physically get in front of the box and use the GUI to stop and restart the process. Is it possibly to remotely run a script to kill OS2RSD.exe if its running and then start it again? I have been unable to figure this out on my own. The OS is OS2/Warp Version 3 if that helps.

• GVim Stop at end of line with arrows

  - by viking

  When using the arrow keys in Vim on Linux, they act the same way as h and l , stopping when the end of a line is reached. GVim on Windows doesn't do this, instead allowing the arrow keys continue past the end (or beginning) of a line and on to the next line. Is there any way to change the arrow key behaviour and cause them to stop at the end of a line like the character navigation keys? NOTE: I am not looking for a way to get to the beginning or end of a line, I realize that 0 and $ do this.

• How do I stop cropping in iMovie?

  - by Javoid

  I'm not certain if 'crop' is the right term. I'm new to iMovie so I may have some of the terminology wrong. When I import a movie, I allow it to resize to the recommended settings instead of full size. Then I drag it from the lower event pane into the project pane. In the 'preview' pane where the movie can be played, the top and bottom of the movie are cut off a little. It's like its converting it to widescreen by cutting off the top and bottom. After I publish the movie in mobile format (it won't allow any larger) it still has the top and bottom removed. How can I stop this? I even tried importing full (original) size and it still didn't help.

• How do I stop someone from saturating my line & wasting CPU cycles

  - by JoshRibs

  My web host shows inbound & outbound traffic with mrtg. I have a steady 3.5mbps inbound traffic from Nigeria. Even assuming the source IPs & destination ports are blocked with Iptables & verifying nothing is listening on those ports, will the traffic still always pass through the switch & "get" to my server (where my server wastes CPU cycles "dropping" the packets)? Assuming I was setup with a hardware firewall, the traffic would still show in mrtg assuming the firewall is behind the switch? So is there any way to stop someone from saturating your 100mbps line, if they also have a 100mbps line? Other than filing an abuse complaint with the kind folks in Nigeria?

• Stop application windows hiding when app loses focus

  - by Bryan

  How can I stop windows on my mac (Mac OS Snow Leopard) from hiding when the app that owns the window loses focus. Not all apps on the mac do this, but Photoshop and Transmission are perfect examples of apps that exhibit this behaviour. It's frustrating when you want to type notes in another app (e.g. word processor), but refer to the contents of the window that hides when you focus the word processor to start typing your notes! There must be an option (or hack) to disable this? I always thought Apple were supposed to be the masters of UI design, but allowing apps to do this seems wrong.
