• Is there a successor to NTFS?

  - by hak8or

  What I am asking is if there is any file system that is known to be a possible successor of NTFS? I am asking because I just bought a new external, and realized that the path to a file, including the file name itself, cannot add up to more than 255 characters. This is known as the "Long File Name" by microsoft. I am assuming this is due to the file system limitation, so I am searching for any possible alternatives. I have a windows 7 based machine, but I am under the assumption that there would be third party software that would work with windows to make the new file system accessible by windows explorer.

• Understanding how memory contents map into a struct

  - by user95592

  I am not able to understand how bytes in memory are being mapped into a struct. My machine is a little-endian x86_64. The code was compiled with gcc 4.7.0 from the Win64 mingw32-64 distribution for Win64. These are contents of the relevant memory fragment: ...450002cf9fe5000040115a9fc0a8fe... And this is the struct definition: typedef struct ip4 { unsigned int ihl :4; unsigned int version :4; uint8_t tos; uint16_t tot_len; uint16_t id; uint16_t frag_off; // flags=3 bits, offset=13 bits uint8_t ttl; uint8_t protocol; uint16_t check; uint32_t saddr; uint32_t daddr; /*The options start here. */ } ip4_t; When a pointer to such an structure (let it be *ip4) is initialized to the starting address of the above pasted memory region, this is what the debugger shows for the struct's fields: ip4: address=0x8da36ce ip4->ihl: address=0x8da36ce, value=0x5 ip4->version: address=0x8da36ce, value=0x4 ip4->tos: address=0x8da36d2, value=0x9f ip4->tot_len: address=0x8da36d4, value=0x0 ... I see how ihl and version are mapped: 4 bytes for a long integer, little-endian. But I don't understand how tos and tot_len are mapped; which bytes in memory correspond to each one of them. Thank you in advance.

• IE Sessions in Terminal Server

  - by Jacob

  Currently we are using WADE middleware for our order processing operation. We have about 40 operators that use 1 terminal server to open IE 8 to access the WADE middleware. To me, it's random, but every now and then someone will come to me and tell me that IE has a "Page cannot be displayed" or "HTTP Error 500" error. I did a bit of testing on my local machine and I never get this error while doing normal operations. Although, when I open one session with username "test" and then login to the wade admin console as admin, I run into problems. I do not run into problems until I logout of the wade admin. Once I logout of the Wade admin, my "test" session says "page cannot be displayed". This makes me think the IE user sessions on the terminal service are cross talking. Does anyone have any possible settings I can change in IE or do you think this is an issue with the middleware? The Terminal Server is Windows 2003, btw.

• What is wrong with my game loop/mechanic?

  - by elias94xx

  I'm currently working on a 2d sidescrolling game prototype in HTML5 canvas. My implementations so far include a sprite, vector, loop and ticker class/object. Which can be viewed here: http://elias-schuett.de/apps/_experiments/2d_ssg/js/ So my game essentially works well on todays lowspec PC's and laptops. But it does not on an older win xp machine I own and on my Android 2.3 device. I tend to get ~10 FPS with these devices which results in a too high delta value, which than automaticly gets fixed to 1.0 which results in a slow loop. Now I know for a fact that there is a way to implement a super smooth 60 or 30 FPS loop on both devices. Best example would be: http://playbiolab.com/ I don't need all the chunk and debugging technology impact.js offers. I could even write a super simple game where you just control a damn square and it still wouldn't run on a equally fast 30 or 60 fps. Here is the Loop class/object I'm using. It requires a requestAnimationFrame unify function. Both devices I've tested my game on support requestAnimationFrame, so there is no interval fallback. var Loop = function(callback) { this.fps = null; this.delta = 1; this.lastTime = +new Date; this.callback = callback; this.request = null; }; Loop.prototype.start = function() { var _this = this; this.request = requestAnimationFrame(function(now) { _this.start(); _this.delta = (now - _this.lastTime); _this.fps = 1000/_this.delta; _this.delta = _this.delta / (1000/60) > 2 ? 1 : _this.delta / (1000/60); _this.lastTime = now; _this.callback(); }); }; Loop.prototype.stop = function() { cancelAnimationFrame(this.request); };

• Why my AD domain doesn't work on my laptop

  - by Frederick Marcoux

  I have installed Windows Server 2008 R2 on a virtual machine with a bridged network card and installed Active Directory. I configured it and when I try to connect my laptop to the domain name, in this case, creationsmicroweb.ca (doesn't exist, don't try, for local only), I can't get connected. My laptop just doesn't see it. I don't know why! There's a resume of my config: Domain Name: creationsmicroweb.ca Forest: new, principal domain controller IP: Fixed (192.168.1.100) DNS Name: none (just for local, I ignored them) NETBIOS name: MICROWEB If someone as found why, please help me! This is for my business that I'm starting and I can't find why it doesn't work!

• booting FreeBSD 9 from USB stick: boot error

  - by ssc

  I am trying to boot FreeBSD 9 from a USB stick that I created following the official guidelines: dd if=FreeBSD-9.0-RELEASE-i386-memstick.img of=/dev/da0 bs=64k Booting fails with a simple 'boot error'. I have used this USB stick for quite a while for the very purpose of booting / installing new OSs, but I tried a different one anyway - same problem. I have also reproduced the issue on a different machine. I've acquired to image file over torrent which AFAIK has an md5 check built in, but I downloaded it again anyway directly from a FreeBSD mirror. Same result. Does anyone have any success with this ? I did not find anything related online which seems to suggest this is not a well-known problem. Does anyone have a thought where else to search for the cause of the problem ?

• Is it safe to buy a replacement laptop battery that has slightly different voltage than the original?

  - by Hugoagogo

  I'm looking for a new battery for my Acer Aspire 4741g laptop. I am trying to get a higher capacity battery. Many sites (like this one and this one) list batteries that are interchangeable with the battery that came with the laptop (AS10D41). These batteries have higher capacity, but also marginally lower voltage (11.1V vs. 11.8V). Is this a problem? Does it mean that the battery is actually incompatible? The replacement battery I am looking at is AS10G3E, and is listed in many places as being compatible with the AS10D41, but nobody makes any mention of the differing voltages. I am trying to find out what kind of problems a lower voltage battery can cause. I know P=IV; with reduced voltage, will the machine draw more current, possibly damaging components? I'm just speculating, but I'm worried about the chance that using a battery at a lower voltage will damage my laptop.

• How can I create a windows shutdown script from powershell/command-line?

  - by David Rubin

  I've read the TechNet pages that describe using computer/user startup/shutdown scripts, and that's great, but I'd like to create those scripts via the command-line (and not have to click around in gpedit.msc). It looks like scripts.ini and psscripts.ini in %SYSTEMROOT%\System32\GroupPolicy\Machine\Scripts specifies the scripts to run, but those don't exist until running gpedit.msc for the first time. Is it safe to create and edit those directly? Or do I need to muck around with Set-GPO or something similar? Thanks!

• would a dynamic wan disrupt a static lan?

  - by JohnMerlino

  So I found out that the cable company use the DHCP to assign the public ip address dynamically. So a subscriber's public facing ip address can change during the length of their subscription. Now what if you remove DHCP on a particular computer, which you plan to use as a web server, so that the machine has a static, unchanging IP address. If the public ip address was to change, would this confuse the Network Address Translation (NAT) and cause some sort of disruption? Please answer in layman terms, as I'm still grasping concepts here. thanks.

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• How to install nvidia drivers (GT 440 ) on Xubuntu 12.10 , screen res gone to 640x480 :(

  - by shaggyjack

  Hi all after days of endless googling I finally gave in and decided to try and directly ask for help. I have just installed Xubuntu and updated to 12.10 on a pretty old (12 years) machine, and I am now struggling to install the correct drivers for the nvidia 440 gt card.. I have managed to get "additional drivers" but the app does not show in the menu, I went through a few procedures which ended up in my screen going no higher than 640x480, and tried all the sudo apt-get variations with nvidia-current and current updates... I think I got the right version of the drivers ( 93.43.07 ) but they won't install from terminal as they say I am running an X server. So I learnt how to shut the graphic interface but then I try and install them from there but after I write the exact same command (sudo home/username/Downloads/NVIDIA-Linux-x86-96.43.07.pkg1.run ) nothing happens and the terminal says something like command not found. I am desperate for help if anybody could point me in the right direction that would be greatly appreciated. There are lots of similar topics on installing nvidia drivers but I seem to understand that current drivers are no good for my old GPU. So if anybody could show me how to install the right version that would be excellent. Thanks in advance! Jack

• Windows 7 Wireless Network Adapter Stopped Working

  - by Andrew B Schultz

  I have a Windows 7 Ultimate machine where the wireless adapter all of a sudden started having trouble connecting to wireless networks. Whenever I go to a new place and try to connect to a wireless network, it says that the DNS server is not responding, and tells me to go unplug the router and try again. After several locations in a row telling me this, I began to realize something was wrong with my adapter, not the routers. I am no longer asked to identify the security level for any new networks (Work, Home, or Public) like I used to be (it defaults to Public now - with the park bench icon). Often, resetting the router doesn't even work. Running the Windows 7 troubleshooter doesn't give me anything better than the advice to reset the router. However, the adapter will still connect to the wireless network at my main office without any problems. Does anyone know why a wireless network adapter can get so finicky so suddenly? Thanks!

• AWS RDS Timeout

  - by warder57

  I know next to nothing about networking/servers. So I'm assuming I'm missing something obvious. All of the resources I can find on this, either don't work or are outdated. I created a brand new AWS account on the free plan. I created a postgres RDS DB instance. I made sure that this RDS instance is set to publicly accessible. This RDS instance has the default VPC/Security Group settings. In order to connect to this DB from my local machine, I used pgadmin3 and followed the instructions provided on the AWS documentation page. Seen here: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToPostgreSQLInstance.html I've double checked all of the information required to connect: Host: whatever.whatever.us-west-2.rds.amazonaws.com Port: 5432 Username: USERNAME Password: PASSWORD When I try to connect to the database, my connection fails due to a timeout. (During step 4 in the above guide.) Can anyone point me to whatever I am missing? Thanks in advance

• Allow READ access to local folders in 2003SBS AD

  - by Dan M.

  Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

• Recycle remote IIS app pool from the command line?

  - by Ken

  Is it possible to recycle an IIS7 app pool from the command line, on a different machine? I've found APPCMD (appcmd recycle apppool my-app-pool), but it only operates on the host it's run on, AFAICT. I heard a rumor there might be a way to do it with Powershell, but I know nothing about that, and I'm apparently not very good at googling for it. I'm using Vista / Server 2008, if that matters. EDIT: I found something called WinRM that somebody claims is able to run APPCMD itself, but I'm not sure exactly how, yet.

• On VMWare Server, how can I specify which Ethernet port should be the one to be bridged?

  - by DrDavid

  My server has 4 ethernet ports; 1 uses a APIPA address to connect to a DroboElite (that's how they're designed to work), 1 is connected to the LAN, and the other two are unused currently. The issue is that VMWare Server seems to have an affinity to the port that's connected to the Drobo, which means that it can never reach the internet. If I disable the Drobo port, everything works just fine. If I enable the drobo port, nothing works (well, the drobo works, but the virtual machine doesn't ;) ) How can I tell VMWare Server to NOT use the drobo port when I'm bridging the connection?

• Is there a way to customise PPD distribution of printer drivers effectively with Mac Os X server?

  - by glenstorey

  Hi, we have two network printers shared via our 10.5.8 Mac Os Server machine. They have drivers provided by the manufacturer that allow job logging (printing with a print code). I've installed said drivers on the server, but when we distribute the printer on our Mac Os clients (using add printer via bonjour) it deploys older drivers that don't support Job Logging. Is there a way to update the store of print drivers (cups drivers?) on the server so it distributes the updated drivers, rather than the older one?

• Create Virtual Image of Laptop before Formatting

  - by Simon Mark Smith

  I have a 3 year old laptop running Windows XP that I used for business. Although I have not used the laptop in over a year, I now want to re-commission it with Windows 7 and a fresh install. Before I do the fresh install I want to create a Virtual Image of the laptop that I can keep and potentially run on my desktop machine should I ever need to access any of the old files/projects that it contains currently. I know that most people will say just copy the files over to your desktop, but my concern is the configuration of the laptop. I used to use it for development and it has older versions of Visual Studio, SQL Server, Active X controls etc, etc than I currently use so I really want to preserve the environment not just the files. So really I am asking what is the best tool-set/method to achieve this? I understand there are free VM tools available but I have never done this before and would appreciate any help.

• How to disable System service from listening on port 80 in Windows Server 2003

  - by Miky D

  I'm trying to install a service on a Windows Server 2003 machine which is supposed to listen on port 80 but it fails to start because some other service is already listening on that port. So far I've disabled the IIS Admin service and the HTTP SSL service but no luck. When I run netstat -a -n -o | findstr 0.0:80 it gives me the process id 4 as the culprit, but when I look at the running processes that process id points to the "System" process. What can I do to get the System process to stop listening on port 80 and get my service to listen instead?

• Ping Access to a Nested VM !! Plz Help

  - by Shivaramakrishnan

  I have a problem in communication between the host and the nested VM.This is my layout. I have installed KVM on host machine having a single nic interface (public ip) running Ubuntu.On top of this,I have VM running Ubuntu.I have installed KVM in this VM too.I then have a VM inside this running a web server. I am able to ping the host from this web server VM and ssh into it.But from host to VM ,ping is being unsuccessful. The VM (named L1hyp) on host was created using libvirt-manager and has IP of 192.168.122.8. The vswitch interface created at host is in default config (NAT-ed). Its IP is 192.168.122.1. Now this VM is also having a vswitch interface which is in default config (NAT-ed).Its IP is 192.168.100.1. The Web server VM is created on top of this L1hyp VM, is having an IP of 192.168.100.186. The Webserver VM uses 192.168.100.1 as its default gw. The L1hyp uses 192.168.122.1 as its default gw. From Host: ping 192.168.122.8 - SUCCEEDS ping 192.168.122.1 - SUCCEEDS ping 192.168.100.1 - SUCCEEDS ping 192.168.100.186 - FAILS Comes up with Destination Host Unreachable From 192.168.122.1. But there is route to 192.168.100.0/24 subnet from host.Ping to 192.168.100.1 succeeds. From Webserver VM: ping 192.168.100.1 - SUCCEEDS ping 192.168.122.1 - SUCCEEDS SSH from web server VM to host succeeds. Can anyone help me out what needs to be modified to have two way communication between the host and Webserver VM at the earliest? I am pondering over this problem for over a week now.

• Deleted one membership table. Possible to import without breaking relationship?

  - by superexsl

  Hey, I hope this isn't going to be tricky/time consuming, so fingers crossed. I'm working with the ASP.NET membership table. However, I've got quite a few other tables that I've built, and most of them have a relationship with the dbo.aspnet_Membership table. I've accidentally deleted the dbo.aspnet_Membership table and can't get it back. There was no major data on it, (as it's on my local machine), but I would really like to copy and paste that one table from another database I have, mainly for the sake of not breaking the schema. Is this possible? I'm worried if I run the Aspnet_regsql.exe tool, it's going to break the schema and remove all data from the tables as well the relationships (which would take a while to re-establish). Is there any way I can import just the dbo.aspnet_Membership table into my current database? Thanks for the any advice!

• USB device is recognized but has no address

  - by SeanMG

  Good day folks, I'm trying to use a USRP1 with GNURadio if anyone knows what any of that is. I am running Ubuntu on a Windows 7 machine via VMware player. When I connect this USRP1 via USB 2.0 drive to Windows 7 it is recognized as Ettus Research LLC USRP1... When I connect the device to Ubuntu through VMware, it shows: usb device fffe:0002 on my removable devices. When I run lsusb I receive the following: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub Bus 001 Device 004: ID fffe:0002 When I run this program that comes with the USRP driver... uhd_find_devices I receive: -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: type: usrp1 name: serial: 00000000 So when I run this program, it does recognize the fact that this device is connected. However, the device has no address, no name, and has a null serial. I need to know the device address so I can run more programs in GNURadio. Does anyone know what the problem is here? Thanks!

• How to monitor the network traffic on a router?

  - by Adi

  Here's my current network set-up: we have 3 users connecting to a Thomson Gateway router (TG585 v8) provided by my ISP. We are connecting over an ADSL line. The problem is that we have a limited data allowance (60GB) and we always exceed it. I would like to monitor how much traffic each computer makes. The best solution would be to install a software on the router (like OpenWRT) which would monitor how much traffic each computer makes. But I couldn't find any replacement firmware that would support my router. The other solution would be to install a software on each machine and then collect all the data at the end of the mount. But that's not a very good think to do. Plus, the users can always shut down the application. Any suggestions?
