• When should .local be used?

  - by hydroparadise

  So, I've set up a few Win Servs in my time and always did the .local thing when there was a router that sepearated my internal from external networks. Now that I'm setting up an *nix box for the first time, does this concept still apply? Do I still want my FQDNs (/etc/hostname) to show .local or .com for all my machines (mixed: linux servers, win workstations) inside of my network. This question comes in context of always having Active Directory hold my hand every step of the way, where now I'm setting up an DNS machine manually.

• Best way to "stream" music / video to my HDTV from my pc?

  - by loj

  My requirement is simple: I have a laptop and a desktop at home that I often use for various media (music, videos etc.) and I want to know what the best (quickest, most seamless, best quality etc) solution for sending this media to my HDTV (and connected sound system). An example would be I'm listening to some music from youtube on my laptop in my living room and want to quickly send it to my tv (which has a sound system) so that I don't have to listen to it through my laptop. I mainly use linux (but a windows dependent solution would be ok too if its the best option). I would greatly appreciate any suggestions. Oh and a wireless solution would be best.

• No Drivers in Ubuntu 9.10

  - by Chris

  I have a Lenovo G550 and I installed Ubuntu on it through Windows and I have no drivers. No sound, no wireless. I previously had installed it through Windows Vista with no problems at all. I now run Windows 7 and cannot seem to get it to function properly. I tried installing the recommended drivers to make sure the proper ones were installed and that still did nothing. Any one have ANY idea what could be happening? I just don't feel like dealing with it.

• Removing integrated video card drivers broke other hardware?

  - by jsnlxndrlv

  I just purchased and installed an XFX ATI Radeon HD 4650 video card. The installation instructions said to remove the old video card drivers before installing the new driver. I did both things, but now every time I start my computer, the Found New Hardware wizard pops up for the following three devices: PCI Device SM Bus Controller Other PCI Bridge Device Furthermore, my LAN port no longer functions. The cable's connected, and the light on the port comes on, but the computer can't find any servers when I attempt to connect with it. The modem and router are working, and obviously I'm able to use the other computer here to post this. What do I do to fix this?

• DNS for route between WAN & LAN

  - by David Maitland

  I have a few machines set up on my internal 192.168.1.* network and i have one public ip, my router is links all ports to on internal linux machine on my network 192.168.1.3. I want to know how to configure the DNS server on my linux box to forward to internal LAN ip's depending on the host name. EG. computer4.83.22.56.12 would find my box then forward to 192.168.1.4 on the local network. This is so i can run multiple web server under one ip. btw, i use Ubuntu. Thanks Dave

• Windows 7 Desktop as Bluetooth Mixer

  - by J.R. Lillard

  I would like to stream all the audio from my Droid X2 to my desktop running Windows 7 via bluetooth. When I pair the two devices I can make this work but the audio plays through the internal speakers. I am actually wanting to listen to everything through a pair of bluetooth headphones. The end result would be that I could listen to music from my phone but easily pause it to listen to audio from the desktop instead. So far I have not had any luck. I thought about connecting the line out to the line in so I could monitor the line in from my headphones. My current setup is wiring the phone to the line in and then monitoring the line in through the headphones. I'm just wanting to eliminate the wire and go wireless the whole way. Is there something in Windows that prevents it from taking an inbound audio stream and sending it out another device?

• How to set up VLAN network

  - by Paddington

  I'm changing my network from having every device on flat network to using VLans. My problem is that we already have a lot of devices on this network(192.168.20.0/24). From theory, I read that each Vlan has to be a different subnet and then I need to configure virtual interfaces on my Cisco router to cater for inter vlan routing. 1) How can I segment this network with minimum down time on the devices already on the network? 2) Can I just create Vlans and leave all these Vlans in the same layer 3 network so that they can go out of the network (I am not too concerned about inter-Vlan routing) or I have to create subnets which means reconfiguring the existing devices (something I do not want).

• How to set up strongswan or openswan for pure IPSEC with iPhone client?

  - by Shabbyrobe

  I'm having trouble finding concrete, up-to-date information for how to set up strongswan or openswan to be used by the iphone's VPN client. My server is behind a budget linksys NAT router. I found this, but it mentions a whole bunch of .pem files with no reference for how to create them. Unfortunately, the "fine" manuals for both packages were quite inscrutable and unfriendly to a novice. I've set up OpenVPN before and managed to get serviceable results very quickly, but after a day and a half of reading out of date docs, I barely even know where to start. Any help would be greatly appreciated!

• Can't access the Internet in VMware Workstation

  - by asunnysunday

  I'm using VMware 7.1.2 in Windows 7 with Ubuntu 11.04 as a guest OS. In the host OS (Windows 7), I can access the Internet without any problems but in the virtual machine I can't access the Internet. I've tried the following but with no success: Use all methods of connecting to the Internet in "Virtual Machine Settings": Bridged, NAT, Custom; none work. Used cabled and wireless connections on the PC - neither of them work. I've used Ubuntu in VMware for several months - previously the Internet was always accessible. Could the cause of this be because I upgraded to Ubuntu 11.04?

• Get OpenVPN clients names to resolve through dnsmasq

  - by Fake Name

  I have a PFSense box running as an OpenVPN server. There are several remote devices that connect through the VPN (as tap devices). The VPN stuff is working, I can access the remote hardware by looking up the IP assigned to each device on the PFSense router. What I'd like is to have it so I can resolve the remote hardware addresses via DNS while on the local network. Note that this is only local-network - remote-device (they're backup boxes). I don't need to have the remote devices resolve using the local DNS forwarding agent. I have the rest of the devices on the network that need to be accessible via DNS report their name during the DHCP process. However, the IP assignment for OpenVPN tap clients, while it is dynamic (which is why I need DNS), does not seem to use the local DHCP server. How can I have my openvpn server add information for it's clients to the dnsmask resolver? Is this setup even reasonable (I'm not familiar with openVPN at all)?

• Page loading hangs and never times out (Apache)

  - by Lucas -luky- N.

  I have set up Apache2 on a guest Ubuntu 10.04 OS (virtualbox). I have created a "big" HTML file (4MB) with only plain text and when I access a page through my local IP address such as http://192.168.0.100 it successfully loads the entire page. However, when I try to access it through my public IP address the browser loads part of the page and then hangs forever on "loading". I can load a simple webpage though. I'm not sure whether it's an issue with my Apache configuration, Virtualbox, Router or Modem. Any clues? Tried enabling Debug and mod_status but didn't find any useful information.

• 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)?

• How can I connect a wired PC to the internet through my Macs wifi connection?

  - by David Weitz

  So I'll probably be buying a USB wifi adapater if I can't get this to work, but I'm trying. I have a wireless router at home and my Macbook Pro is connected to said wifi. My desktop doesn't have a wifi connection, but I've connected my macbook with my desktop via crossover cable. I enabled internet sharing on my macbook, but my Windows 7 desktop can't get a connection. I tried just regular file sharing and that works fine, but the internet sharing doesn't. I assume the goal is to get my PC to see my mac as the default gateway, but I've had no luck manually setting it. Here's the ifconfig output on my mac and my attempt at settings on windows: http://i.imgur.com/uJfUz.png

• How can I set a network connection as metered?

  - by Sam

  I would like to set a network connection as metered. I can't find how to do this; it seems to have changed in the upgrade from Windows 8 to 8.1. I tried following the steps in the official metered connection FAQ. However, when I open the connection, there is no Data Usage heading nor a Set as a metered connection option. I tried this on two different computers, both running Windows 8.1. I also tried doing this for both wireless and ethernet adaptors. Here's what the connection screen looks like. I've cropped the empty space from the image. How can I set the connection to metered?

• WAN and LAN setup for IPv6

  - by neu242

  We just got a IPv6 /48 range (a gateway and an IP address) for our company, but I'm unsure about how to set it up. We use FreeBSD 8.4 (pfSense 2.1) as a router/firewall. Currently we have IPv4 setup with a WAN towards the internet, and a NAT-ed LAN behind it for office PCs. We want to keep the LAN network for security, and we want IPv6 addresses from the /48 for all office PCs (without NAT). The WAN is configured with the IPv6 gateway 1111:2222:3333::1/48 and interface address 1111:2222:3333::2/48. But when it's configured this way, I guess it's impossible to fit the LAN on a /64 within the /48? I believe I should configure the WAN subnet on 1111:2222:3333:1::/64 and the LAN on a subnet like 1111:2222:3333:2::/64. Is this something I can configure myself, or do I have to ask the ISP to configure that routing for me?

• Taskbar Disappears Over Remote Desktop Connection When Outside Local Network

  - by CMikeB1

  I've got a machine on my home network running Windows Server 2012 (Based on Win8) and rather than attach a monitor I remote desktop in and it works fine on my local network. The problem is, when I try to access it from outside my local network the taskbar disappears completely. When I minimize an application rather than minimize to the taskbar it simply closes the window as small as it can as if the taskbar never existed (see photos at ). I've messed with the connection properties (show/hide desktop background, etc.) with no luck. I've used the following methods to remote in and they all are fine when on the local network and taskbar-less from outside: Remote Desktop Connection on Mac Remote Desktop Connection on Windows Jump Desktop on iOS using RDP To access the computer from outside my local network I'm using a Linksys router and mapping to the server IP, port 3389.

• Remote HTTP to FTP

  - by jamd12

  I am on a very slow download with the internet that I have and unfortunately I only have access to expensive and slow wireless or satelite. I have set up an FTP with a computer supplier locally who has a nice 2 Mbps speed and am trying to set up a way of adding links remotely (Hotfile, rapidshare, Fileserve, etc.) so that they can be downloaded onto the FTP and then transfered a few times a week manually onto a portable HDD. On my home PC I use Internet download manager for all my downloads. Is there a simple way that I can add links remotely to Internet Download Manager on the FTP or perhaps another solution? The OS on the FTP is Linux - I use Windows XP SP3 and Windows 7. I have not used FTP very much before so any suggestions on how best to do this would be much appreciated.

• How do I bridge connections in Debian?

  - by Josh

  In windows I can select Local Area Connection and Wireless Network Connection, right click and select Bridge Connections How can I achieve the same effect in Linux? (Debian to be exact) Pretty much I want Computer B to connect to Computer A via ethernet cable. Well Computer A is connected wirelessly. Allowing Computer B to get on the internet. == UPDATE == I've enabled IP forwarding and used the following iptables command: iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE I'm still unable to access the internet from Computer B though.

• Set Up Remote Desktop at Home

  - by Rev

  I'm sure this has been asked before, but I'm unable to find a clear set of instructions. I'm currently using LogMeIn Hamachi to enable Windows 8's Remote Desktop feature on my home computer (running Win8 Pro x64). Unfortunatley, I can't use this method to access my home computer from my Surface Tablet, as I can't install in the Hamachi client. So how can I set up Remote Desktop without using LogMeIn Hamachi? A link to a noob-friendly tutorial would be greatly appreciated. I haven't been able to find anything that I understand (and I am pretty technical, router stuff just stumps me for some reason). EDIT: And I don't want to use a third party service like TeamViewer, in my experience those tools are laggy and quite horrible. The Remote Desktop feature has been excellent.

• How to bridge two networks via VPN (IPsec)?

  - by polemon

  I'd like to do a Site-to-Site bridging with VPN (IPsec), how do I do that? On the local side, I have a DrayTec Vigor2910, it is supposed to be able to manage IPsec tunnels. Anyway, I need to have several VPN tunnels to various sites, but how exactly do I do that, If the only router I can configure, is the local one? As I understand it, I'd need some sort of VPN server or client, or whatever on the other side. In any event, please clarify that issue. Thanks.

• 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?

• bat file to disable ethernet adaptor and then reenable it after windows log in

  - by jaslr

  When I log into Windows 7 I need to wait 10 seconds and then disable the Local Area Connection (ethernet adaptor) and then reenable it. I have looked through the suggested answer: Enable/disable wireless interface in a bat file but that seems irrelevant as it just toggles the current state. From what I can tell I need to include: netsh interface set interface "Local Area Connection" DISABLED netsh interface set interface "Local Area Connection" ENABLED but I'm unsure of the wait time or how I can have this start after Windows has successfully logged in. What's the best approach here?

• Ubuntu 10.4 No internet

  - by Keeper780

  I have Ubuntu 10.4 dual booted with Windows Vista on a work Lenovo R61 laptop. The home and work wireless connection were working fine. I lost all internet connection at work. The IT guy clearly knew nothing about Linux. Since he 'fixed' it get nothing, no wlan signal the Network manager icon was gone, no internet. I still have the live disc and if I run from the live disc the connections are there and everything works perfectly. How do I restore the internet easily on my laptop. I have been using Linux for 3 Years but I am still a bit of a newbie, this is the first major problem I've had in three years. It's driving me nuts. Thanks
