• How to setup VPN on home network

  - by Tone

  I am a software developer. I travel and sometimes have a need to access my files at home and tweak other family members computers. I would like to connect to my home network via VPN and then RDP into whatever machine i need to. Currently i have a Windows Server 08 machine, which is my file server, database server, web server (for development work), source control repository, etc. (and also somewhat of a workstation when i need it to be). I want to use this same machine to run my VPN through. I have a linksys WRTG54 router. My ISP is AT&T DSL, with a dynamic IP address - so i'm assuming I'll either need to request a static IP or sign up with one of those static ip services.. where it keeps your dynamic ip synced up with a static one. While I do understand software engineering I am no expert in networking. What do i need to do to setup my VPN?

• Tips for locating my stolen computer

  - by user379468

  I'm in a bit of a panic, my new Powerbook laptop was stolen. I had no mobile me, or security software installed on the computer. I have the mac address of the computer as well as the serial number. Is there a hacky way to do this? I was even thinking perhaps of trying to use bluetooth, I know I had it set to discoverable. and I know the "name" of the computer, perhaps there is app that can scan the names of bluetooh computers in the vicinity? If there some third party you can get to scan the internet for your mac address? Any glimmer of hope would really help

• "bin/sh: can't access tty; job control turned off” error when running shellcode"

  - by Nosrettap

  I'm writing shellcode to exploit a buffer overflow vulnerability on a server. To do so I have port binding shellcode that I send to the server and then I run (from a linux terminal) the command telnet serverAdress 4444 where 4444 is the port which I have opened up. The hope is that I will receive a shell back that I can use to execute commands. However, I always end up with the command bin/sh: can't access tty; job control turned off I can't change any of the server code, and I believe the shellcode is correct because I got it from this website (http://www.tsirogiannis.com/exploits-vulnerabilities-videos-papers-shellcode/linuxx86-port-binding-shellcode-xor-encoded-152-bytes/). From my research, it appears that this may have to do with the mode that my terminal is running in (something called interactive mode...or something like that). All computers involved are linux machines and the machine that I am on is running the latest version of Ubuntu. Any ideas what this job control error means and how I can fix it?

• Does Windows 8 support the "start in [folder]" property for shortcuts?

  - by FumbleFingers

  I use Foobar2000 to play music, and for years now I've run it in what they call "portable mode". What that means is that the program itself isn't actually "installed" in the traditional Windows sense. All "non-system" dll's required by the application are in the same folder as the executable; earlier versions of Windows find them there, and everything runs fine. But Windows 8 fails because it doesn't find them. I want things set up this way because I keep Foobar2000 on a portable external hard drive, so I can just move it between different computers without having to go through the Windows install process. With all previous versions of Windows, I could either directly run the application from File Explorer, or create a shortcut on the desktop with the "start in folder" property set to the actual folder containing the program. I can still use the first method, but I want a shortcut! Is there any way to do what I want?

• How do I image my hard drive for backup? Or do I just need to backup the files?

  - by NoCatharsis

  I have never imaged a hard drive, so I don't know what software to use or how to prepare my system for imaging. Is this the best way to backup? In the past, I've always just kept a copy of my important files on an external drive and in Gmail or DropBox for smaller stuff, but it would be nice to just take one image and restore from that if something ever goes wrong. Thanks for the help. EDIT: I'm sorry, I forgot to mention the OS. I would like to do this for my home and work computers, which are Vista and XP respectively. And actually I'm about to upgrade to Windows 7 at home, so details on that would be appreciated too.

• System Center 2012 R2 System Discovery Network Utilization

  - by AtomicReaction

  I'm in charge of a deployment of Microsoft System Center Configuration Manager 2012 R2. Currently, I'm working through the discovery methods and trying to decide how to enable automatic discovery of systems and users. On Microsoft's documentation, they warn that Configuration Manager Automatic Discovery traffic can get pretty significant if you aren't careful in your implementation. Can anyone who has used this give me some information on how much traffic I should expect? We currently have around 1000 computers and 4000 user accounts in Active Directory. Thanks!

• Minimum rights to access the whole Users directory on another computer

  - by philipthegreat

  What is the minimum rights required to access the Users directory on another computer via an admin share? I have a batch file that writes some information to a few other computers using a path of \\%COMPUTERNAME%\c$\Users\%USERNAME%\AppData\Roaming. The batch files run under an unprivileged user (part of Domain Users only). How do I set appropriate rights so that service account can access the AppData\Roaming folder for every user on another computer? I'd like to give rights lower than Local Admin, which I know will work. Things I've attempted: As Domain Admin, attempted to give Modify rights to the C:\Users\ directory on the local computer. Error: Access Denied. Set the service account as Local Admin on the other computer. This works, but is against IT policy where I work. I'd like to accomplish this with rights lower than Local Admin. Any suggestions?

• Share the DVB card on windows 7 [closed]

  - by Bashar Kernel

  I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

• Linux QoS (Skype / BitTorent / SIP / HTTP priority)

  - by Andre

  We are configuring a linux box that will act as internet gateway for an office of 30-50 computers. We are using iptables/HTB for traffic shaping. Is there a way to match traffic on L7 level? It's easy to identify traffic by TCP/UDP ports (like SIP and HTTP). But what if we are dealing with Skype & BitTorent? It was surprise for me that there is no powerful and matured sulution for tasks like this. I found only l7-filter (http://l7-filter.clearfoundation.com/) patch for the Linux kernel, but it's no longer supported (it seems to). Moreover it couldn't be compiled with modern Linux kernels. The only option I found was to use a Cisco router. Are there other ways to identify and shape Skype and Bittorent traffic?

• Can DVI look different?

  - by queueoverflow

  I have a desktop with an nVidia GT 9500 which has two DVI slots. I have a 24" TN-Panel TFT on that and it looks pretty good. Then I hooked it onto the DisplayPort of my ThinkPad with the Intel HD 3000 card with an DP-DVI adapter and I think that the fonts look even clearer. Both computers run Kubuntu 12.04, although the ThinkPad is freshly set up, while the desktop is migrated from the previous release. Is this a hardware thing or is it just some setting in the anti-aliasing or sub-pixel-hinting?

• Duplicate of IPSEC certificate template not displaying

  - by Tim Brigham

  I am working on getting IPSEC working on computers outside my domain. I am unable to get a duplicate of the IPSec Offline Request template to show on the web interface. My CA is 2008 R2 Enterprise and the permissions on the template should be adequate to allow me access (my account has read and enroll). If I publish the original template it functions as desired. I also have other custom templates in use (although using autoenrollment). The duplicate is almost identical to the original, excepting that it has a longer validity period and the private key is marked as exportable. How do I debug at this point?

• Mount cifs share anonymously

  - by churnd

  I have a Windows 2003 Server sharing out a few folders as read-only to "Everyone". The server is a domain member, so I'm not able to connect to the share on computers that aren't on the domain without passing some form of credentials. I have a linux box that I want to mount the share on at startup, so I want to put the share mountpoint in fstab. I have this setup by specifying a credentials file that is only readable by root, but I would rather either not use a credentials file or specify some guest/anonymous user. Can I do that, & if so, how?

• Is it possible to boot from internet?

  - by Calmarius

  Let's assume the following situation: you have a computer with empty hard disk, and you don't have a CD, floppy, pen drive nearby to boot the computer from. But you have connection to the Internet. Modern computers support network booting using PXE, but I haven't found anything regarding booting via the internet. So, is it possible to use PXE to load an image from the internet and boot it? By having a running system (even a minimal Linux) in RAM, it should be possible to install it on the hard disk, and build up a working system from here.

• Recover deleted files on windows 2008 file server

  - by aniga

  We have recently been hit by a weird virus which made all files and folders a system files/folders and also it hid all files and folders par some weird ones it created including: ..exe porn.exe secret.exe password.exe etc We have managed to restore the files with attrib command to unhide and unmark them as system files however we have noticed that we are missing some 4 to 5 folders of which (based on my luck) 2 of them are the two most important client we have. I am not sure if these files were deleted by the worm/virus or by my colleagues who are not owning up to them but the files are now gone. Worst of all, we do not have any backup what so ever (Yes I know, we should not have done that but it is a lesson learned and since last night we have created two forms of backup systems one to external device and one on the cloud, but I doubt any of that will help us now) We have 1 Windows 2008 File server and 4 client computers based on Windows 2007. I would be grateful if anyone can help us on how we can recover from this disaster which could potentially put us out of business.

• Ensure a process is running on a remote computer

  - by awilinsk

  We have about ten client computers ranging from Windows XP to Windows 7 that have a little program that runs in the tray. This program needs to be running at all times and sometimes it either crashes or a user exits the program. We would like to be able to check every hour or so to see if this program is running. If it is not running, it should be started. I have tried using powershell on one of our servers to get the process from a remote computer and if it doesn't find it, to start it. But, that fails because it cannot start the process as an interactive user. I tried setting up a task in task scheduler, but Windows XP task scheduler is not very good or configurable. We would like this to be as easy to administer as possible. What would be the best way to do this?

• Computer connects to lan, but not the internet

  - by Jay

  I have a computer with Vista Home that can connect to the router, but it cannot get on the internet. I cannot ping google.com, the request times out. I've tried this on two separate networks and have no trouble with other computers connecting. I've renewed ipconfig, reset winsock, updated the wireless adapter, and the hosts file looks fine. I've tried disabling the firewall as well as a direct wired connection. I did a scan with Norton and it didn't find anything. Is there anything else I can try before resorting to a system restore? Update (Copied from Answer) Windows Update was able to find updates and install them (though, they could have already been downloaded previously). When I pinged Google by using their IP 66.102.9.103, it said it lost 25 percent of the packets. I successfully flushed the DNS but it didn't help. Also, I found safe mode with networking works fine.

• Block Websites at Work

  - by user791022

  At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

• Lighttpd based server issues crop up when port forwarding

  - by michael

  I have four host computers running lighttpd webservers. they are sitting behind a hspa modem, which each occupying a http port between [81 - 84]. 80 is taken by the modem itself. The port forwarding is setup correctly, however, only a portion of any webpage I request from any of the hosts comes through (they all fails after %20 of the page). If I put the host on port 81 into the dmz, it serves pages fine. The others do not respond to the dmz treatment. Is it possible the web content on the hosts somehow require ports aside from their respective http port? Or is it possible that even though the server.port in the lighttpd_ssl.conf file is set, the individual hosts are still expecting to serve on port 80? I am not familiar with lighttpd, nor did i set them up. they are running on video encoders i purchased. I can grab any files from them required for further information on the problem.

• Can i change the subnet on the vpn side of a server without having to change its whole lan (to avoid collission)

  - by Gusty

  Ohai, ive got a xp server with a client connecting via VPN. Problem (as we all know) is that sometimes the subnets clash. Instead of changing the whole server network every time this happens, cant i just have the server appear to have a different subnet to vpn clients? I have no interest in accessing other computers than the server on its LAN. I tried just turning off automatic dhcp in the servers vpn settings and changed it to 172.31.255.x. The client gets the address assigned alright and it can ping 172.31.255.1 but i cannot ping the server name (because the dns on the clients vpn connection points at 192.168.0.1?) wisdom? PS everything worked until the client hit a network with the same subnet as the server lan. thanks

• Using git with cgit for decentralized/centralized development

  - by polemon

  I plan to use git for hosting my projects on my server. I've read about cgit, git-daemon, and I more or less decided to use those tools. But general use is still kind of confusing for me. What do I need to set up on the server, to push my files onto it. And when the files on the server are newer as the files on my computer, how do I merge them? Also, I use, say, two computers where I develop. How do I merge from one computer to the other? Also, when two people are working on the same project, how do they merge their local repos from one another? As you probably can tell by now, I come from SVN, but I've worked with Mercurial and now I'd like to test git.

• How to prevent Google Toolbar being installed in Portable Firefox?

  - by HyperHacker

  Recently, the campus computers installed Google Toolbar in Firefox. Now, I have no use for this toolbar, so I don't want it there. For that and other reasons, I installed Portable Firefox on a USB stick and use that instead. Somehow, when I log into one of these machines and start Portable Firefox, guess what? "Thank you for installing Google Toolbar." No! I don't want some IT guy choosing what extensions to install on my personal Firefox on my USB stick. I can uninstall it but next time I log in, it comes right back. I suppose PF is for some reason reading things from the local disk, or there's some kind of background process installing it? How do I prevent extensions being installed without my consent?

• how can I get rid of duplicate administrators on 2 macbook pro's

  - by BCITY

  I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

• Compatible case?

  - by Rick

  Hello everyone, first of all, I'm not sure where this question should go. So I've looked around and found the 'hardware' tag used in superuser.com please forgive me if I'm posting this on the wrong site. I'm new to the hardware part of computers. I've been looking around for a few months and now is the time to make my choice. I want to build my own computer and I think I got all the items I need. I want to know if the case and the motherboard I've chosen are compatible or if you could tell me how to check if they're compatible I want to know if they fit. Here's the motherboard/processor/memory package And this* is the case I'd like to fit it in. I'm sure that all the other stuff I might need I have with me already. Thanks in advance -Rick *See my comment, I may not post two hyperlinks due to spam protection
