• 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.

• Garbled text in Screen [closed]

  - by Prabin Dahal

  The graphical Interface in my system is garbled with some text. At the beginning I thought it was due to java and tomcat that I installed. But after removing java and tomcat, it is still the same. I am using ubuntu server and i have installed xfce desktop environment with oboard softkey I have added my dmesg output to this message. What is the problem here. I am not able to figure it out. Thank you for your help.

• Squid + Dans Guardian (simple configuration)

  - by The Digital Ninja

  I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

• Forward all traffic through an ssh tunnel

  - by Eamorr

  I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance, Regarding Eduardo Ivanec's question, here is a netstat -i any port 7000 -nn dump from x.x.x.218: 14:42:15.386462 IP 172.16.1.224.40006 > 172.16.1.218.7000: Flags [S], seq 2804513708, win 14600, options [mss 1460,sackOK,TS val 86702647 ecr 0,nop,wscale 4], length 0 14:42:15.386690 IP 172.16.1.218.7000 > 172.16.1.224.40006: Flags [R.], seq 0, ack 2804513709, win 0, length 0 Update 2: When I run the second command, I get the following error in my browser: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://109.123.109.205/index.php Zero Sized Reply Squid did not receive any data for this request.

• Flex 4 + Apache Ant, Cannot Load FlashPunk Libraries

  - by SquareCrow

  I have been searching google, Apache Docs*, and FlashPunk forums looking for an answer to this: I cannot get Ant/Flex to find and compile the FlashPunk libraries. Here is my build.xml. [code] <!-- Fetch the JAR full of Flex tasks if it is not already in the source directory --> <copy file="${FLEX_HOME}/ant/lib/flexTasks.jar" todir="${SOURCE_PATH}"/> <!-- Add flextasks to the project --> <taskdef resource="flexTasks.tasks" classpath="${SOURCE_PATH}/flexTasks.jar"></taskdef> <!-- Release build Flash Player 10.1 --> <target name="build"> <!-- Build the FlashPunk library --> <echo message="building swc..." /> <compc output="FlashPunk.swc" keep-generated-actionscript="false" incremental="false" optimize="false" debug="true" use-network="false"> <include-sources dir="${FLASHPUNK_PATH}/net" includes="**/* flashpunk/utils/* flashpunk/masks/*" excludes="**/*.TTF **/*.png"/> <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/> </compc> <echo message="building swf..." /> <mxmlc file="${SOURCE_PATH}/epOne.as" output="${OUTPUT_PATH}/epOne.swf" debug="false" incremental="false" strict="true" accessible="false" link-report="link_report.xml" static-link-runtime-shared-libraries="true"> <optimize>true</optimize> </mxmlc> </target> [/code] Results in many errors of the type "Definition net.flashpunk.masks:Grid could not be found" even though when I open the directories I can see the *.AS files right there. Sorry if this is very basic. I am piecing together knowledge of Ant from docs and tutorials. *I decided to use Ant because neither FlashDevelop for Windows nor Eclipse for Linux seemto work for me.

• CentOS - massive usage on loopback interface

  Hi, I have a CentOS installation which is running fairly smoothly. Today I ran ifconfig mainly to see what sort of usage has been coming across the ethernet interface, and to also check my link speed. This is what I ended up seeing for the loopback device: lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:10301085132061223274 errors:0 dropped:0 overruns:0 frame:0 TX packets:13981054163812689233 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:11783901785008000095 (0.6 EiB) TX bytes:10333501021200548281 (0.9 EiB) This just feels completely wrong - almost an EiB of data? Any assistance in tracking down the source of these statistics would be greatly appreciated.

• pam_filter usage prevent passwd from working

  - by Henry-Nicolas Tourneur

  Hello everybody, I have PAM+LDAP SSL running on Debian Lenny, it works well. I always want to restrict who's able to connect, in the past I used pam_groupdn for that but I recently got a situation where I has to accept 2 different groups. So I used pam_filter like this : pam_filter |(groupattribute=server)(groupattribute=restricted_server) The problem is that with this statement, passwd doesn't work anymore with LDAP accounts. Any idea why ? Please find hereby some links to my config files : Since serverfault.com only allow me to post 1 link, please find hereunder the link to other conf files : http://pastebin.org/447148 Many thanks in advance :)

• Local network cache of PHP and Apache2 on Win Server 2008 R2

  - by Ahmed Benlahsen

  Software configuration : I have a new server with Windows Server 2008 R2 installed via VMWare. I have installed Apache2.2, PHP5.2 and MySQL5.5 as separate packages. Issue : On my first installation of my application, all works great. When I updated some JS and CSS files and accessed my application again from a PC on local network, I got the old JS and CSS versions. When I access the same application on local server I got the latest versions of those files. Link of my application on local server is : http://localhost/BADIL Link of my application from local network is : http://LOCAL_SERVER_IP/BADIL I think that must be some cache but I don't know where. Maybe on Win Server 2008 R2 or on VMWare? The question is: Why, when I access my application on the server, everything works fine, but when I access the same application from a local network, I do not see the updated versions of JS and CSS files?

• how to use iis 6.0 redirects?

  - by payling

  I'm attempting to use the below reference to create a re-direct for my local site with no luck. http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/6b855a7a-0884-4508-ba95-079f38c77017.mspx?mfr=true I want absolute links on my local site that point online to point to my local site instead. example absolute link [http://online.com/products] when I click the local version I'd like it to redirect to: [http://offline/products] I want to preserve everything after the domain name and append it to the server (local) name so that when I click a link it will redirect to the local site and not the online version. I've tried [http://offline$S] but that doesn't append the "suffix" /products the way I thought it should. What's going on here?

• IDN and HTTP_HOST

  - by Sandman

  So, when I want to link my users to a specific page I always use (in php): "http://" . $_SERVER["HTTP_HOST"] . "/page.php", to be sure that the link points to the page they're currently surfing (and not one of the server aliases). But with IDN names, HTTP_HOST is set to "xn--hemmabst-5za.net" (for example) - which of course works but doesn't look very nice. Is there a way to have HTTP_HOST set to the correct IDN name in these cases (in this case - "hemmabäst.net")? I rather do it in Apache before it comes to PHP, because otherwise I'd have to replace all my usage of $_SERVER["HTTP_HOST"]. Any ideas?

• VPN - force a selective range of ip to run on VPN (linux)

  - by Francesco

  Preface: I know there are similar question here and there however I'm a kind of newbie on Net stuff so I need an answer on this specific scenario, hoping that can help others too as it is a common problem Let say I cannot do anything on the local switch to change the local ip range, I don't want to use any complicate trick as use VMachine to hide the local ip range but I want to use net tools to solve the issue. Scenario my local net assign me an IP of this class 192.168.1.xxx (ex. 192.168.1.116) and my VPN (VPNC) assign me IP of same class 192.168.1.xxx (ex. 192.168.1.247) Obviously I need VPN to access local address (ex. 192.168.1.100) but when I open any address of the class 192.168.1.xx the route point to my local net and not to the VPN ones. I'm on linux and i'd like gui solution (network manager) in case it is not possible let play with route command. here what network manager offer me: Here my actual route once connected to the VPN: Here some route information (route -n) Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 182.71.21.106 192.168.1.1 255.255.255.255 UGH 0 0 0 wlan0 182.71.21.106 192.168.1.1 255.255.255.255 UGH 0 0 0 wlan0 192.168.1.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0 192.168.1.246 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 Here my ifconfig : ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.1.247 P-t-P:192.168.1.246 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:3415 errors:0 dropped:0 overruns:0 frame:0 TX packets:2525 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:3682328 (3.6 MB) TX bytes:402315 (402.3 KB) wlan0 Link encap:Ethernet HWaddr 4c:eb:42:06:a3:a6 inet addr:192.168.1.116 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::4eeb:42ff:fe06:a3a6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:72598 errors:0 dropped:0 overruns:0 frame:0 TX packets:42300 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:76000532 (76.0 MB) TX bytes:13919400 (13.9 MB) The Question So basically I would like to add a rule to force this particular address (192.168.1.100) on the VPN and not on my local net

• Unleash AutoVue on Your Unmanaged Data

  - by [email protected]

  Over the years, I've spoken to hundreds of customers who use AutoVue to collaborate on their "managed" data stored in content management systems, product lifecycle management systems, etc. via our many integrations. Through these conversations I've also learned a harsh reality - we will never fully move away from unmanaged data (desktops, file servers, emails, etc). If you use AutoVue today you already know that even if your primary use is viewing content stored in a content management system, you can still open files stored locally on your computer. But did you know that AutoVue actually has - built-in - a great solution for viewing, printing and redlining your data stored on file servers? Using the 'Server protocol' you can point AutoVue directly to a top-level location on any networked file server and provide your users with a link or shortcut to access an interface similar to the sample page shown below. Many customers link to pages just like this one from their internal company intranets. Through this webpage, users can easily search and browse through file server data with a 'click-and-view' interface to find the specific image, document, drawing or model they're looking for. Any markups created on a document will be accessible to everyone else viewing that document and of course real-time collaboration is supported as well. Customers on maintenance can consult the AutoVue Admin guide or My Oracle Support Doc ID 753018.1 for an introduction to the server protocol. Contact your local AutoVue Solutions Consultant for help setting up the sample shown above.

• Tuxedo Runtime for CICS and Batch Webcast

  - by Jason Williamson

  There was a recent webcast about the new Tux ART solution that we released last month. Here is the link to hear Hassan talk about that Link to Listen to Webcast Below is the market speak about what the webcast is about and what you will hear. From my own experience, there is certainly an uptick in rehosting discussions and projects with customers all around the world. The notion that mainframes can be rehosted on open system is pretty well accepted. There are still some hold out CxO's who don't believe it, but those guys typically are not really looking to migrate anyway and don't take an honest look at the case studies, history and TPC reports. Maybe in my next blog I'll talk about "myth busters" -- to borrow some presentation details from Mark Rakhmilevich (Tuxedo PM for Rehosting). *********** Mainframe rehosting is a compelling approach for migrating and modernizing mainframe applications and data to lower data center cost and risk while increasing business agility. Oracle Tuxedo 11g with CICS application runtime (ART) capabilities is designed to facilitate the migration of IBM mainframe applications by allowing these to run on open systems in a distributed grid architecture. The brand new Oracle Tuxedo Application Runtime for CICS and Batch 11g can significantly reduce your costs and risks while preserving your investments in applications and data. In this on-demand Webcast, hear from Oracle Senior Vice President, Hasan Rizvi, on how Oracle Tuxedo 11g with CICS application runtime capabilities is changing the way customers think about mainframe migration. You'll learn: * What market forces drive mainframe migration and modernization * What technologies and capabilities are available for migrating mainframe transaction processing and batch applications * How Oracle brings rehosting technologies to a new level of scalability, robustness, and automation

• Fast Society Creates Mini and Mobile Temporary Social Networks

  - by ETC

  You’re out on the town or at a convention with a bunch of friends. How do you keep in touch with the entire group simultaneously? Fast Society offers a smartphone-based solution: a temporary social network for group talking, texting, and more. Fast Society was originally an iPhone only application and has recently updated to include and Android app too. The premise is simple: You set up a Fast Society group, link your friends into it, and for that night (or convention weekend) you’re all part of the same mini group. You can text the entire group, share pictures, set up sub-groups (let’s say that half your group is going to stay up late and party while half need to hit the rack to get up early for presentations, you can create a new group for the night owls to communicate), share your location, and send in-app and SMS messages to the entire group.

• iStack for iPad

  - by Jonathan

  The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

• Dual monitor webbrowsing with Firefox - Addon that opens links on the other window?

  - by raegadfsgfsdg

  I often browse news aggressors like Reddit.com and I want to be able to have one Firefox window open on each of my two screens, and when I middle click on a link on my left screen, it will open up the tab on my right firefox window. I know that there are some plugins that can open up new windows, but if I do that I'll have to many windows open and I'd rather manage my open news stories via tab bars rather than with windows (clearer, more efficient to browse, and easier to bookmark). Is there a Firefox addon with which I can middle click on a link and it will open it in a new tab in my other window?
