  • 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 to setup THIS IPv6 network

    - by Revolter
    I have a network mapped like this : just to experiment IPv6 connectivity, i want to configure my LAN network using IPv6, can some one explain me how to convert the connection between the Desktop and the Laptop to IPv6 without loosing the internet connection ? I don't want to access IPv6 internet, I need to keep my v4. So the end result will be something like an full-IPv6 Laptop accesing IPv4 internet over a some-how-configured Desktop that acting as a NAT.

  • Audio Line-In on Ubuntu/Linux Mint

    - by hahuang65
    I'm currently on Windows, and want to switch to Linux, but some hardware issues are preventing me. Mainly, I have a sound card that supports Line-In. On Windows, anything I plug into the line-in gets outputted to the speakers. However, when I installed Linux, because there is not a control application that comes with the driver, I have no idea how to set this up. I tried going to the sound settings and it doesn't seem to be there. I also want to configure it for 2.1 sound, and do not know how to do that... Anyone here done it before? Thanks in advance for the help!

  • Iptables port mapping from two PCs to one

    - by Anton
    We have 3 PCs, two of it are connected to internet (both of it have 2 NIC) PC1: eth0 - 1.0.0.1 (external IP) eth1 - 172.16.0.1 (internal IP) PC2: eth0 - 1.0.0.2 (external IP) eth1 - 172.16.0.2 (internal IP) PC3: eth0 - 172.16.0.3 (internal IP) Now we want to map port 80 from PC1 and PC2 to PC3. But there is the problem: iptables port forwarding works well from PC1 or PC2, but only in case if PC3 have PC1 or PC2 as gateway. So, question is: can we have port mapping from both PC1 and PC2 regardless of gateway settings on PC3? Thank you in advance.

  • Throughput and why do ISPs sell too much bandwidth?

    - by jonescb
    I hope the question made sense how I worded it. :) I've been wondering, maximum theoretical bandwidth is measured as RWIN/RTT (Window size / round trip time) Source 1 and Souce 2 So if a major city only 100 miles away gives me a ping of 50ms, and I have the default 64kb TCP window size then my maximum throughput will be 12.5Mb/s. Everything further away would give me a higher ping and therefore a lower throughput. Is there any reason to buy something like FiOS with a 50Mb/s or greater connection? Will you ever be able to reach that kind of speed? I know you can increase the TCP window size to increase throughput, but it has to be at both ends which is a deal breaker because you can't control the server. I'm assuming other network protocols like UDP aren't quite as affected by latency as TCP is, but how much of overall network traffic does non-TCP make up vs TCP. Am I just misguided about how throughput works? But if the above is correct, then why should a consumer like me buy way more bandwidth than can be realistically used. Maybe the only reason is for downloading multiple things at once, or one thing from multiple servers/peers?

  • Mirror network packets from WiFi to Ethernet in an ASUS Router RT N53

    - by fazineroso
    I have an ASUS RT N53 router, running the default firmware (Linux 2.6.22 with busybox and uclibc). I need to capture data packets from some Wi-Fi devices I have connected to that router (iPad and some smartphones), but the router is not forwarding any package coming from Wi-Fi devices to the Ethernet Ports. Any idea how can I proceed? Available tools in the router are iptables (no tee option, though), ebtables, brctl... Currently the ethernet and Wifi devices are forming a bridge: # brctl show bridge name bridge id STP enabled interfaces br0 8000.50465dc06be2 no vlan0 eth1 No ebtables rules: # ebtables -L Bridge table: filter Bridge chain: INPUT, entries: 0, policy: ACCEPT Bridge chain: FORWARD, entries: 0, policy: ACCEPT Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

  • Router behind Router--second router (and its clients) cannot be "seen" even after both routers are D

    - by Trioke
    Couple of terminology I guess I should get out of the way for consistency's sake throughout the post: External Router/Modem - SMC 8014WG - External IP 173.32.144.134 - Internal IP 192.168.0.1 Internal Router - LinkSys WRT120N - "External" IP of 192.168.0.175 - Internal IP 192.168.1.1 - Connected via Ethernet Cable (a really long one, from the basement to the second floor) PC - IP 192.168.200 - Connected Wirelessly via WAP2 Personal. Laptop - Used to try and diagnose the problem, a 4th machine to the setup which won't be part of the final setup once everything works. The actual problem: I've tried setting the LinkySys router as a DMZ'd client on the SMC router, and then DMZ'd the actual PC on the LinkSys. So the DMZ looks like this: On the SMZ, client with IP 192.168.0.175 is DMZ'd. On the LinkSys, client with IP 192.168.1.200 is DMZ'd. No dice. I then tried port forwarding the necessary port on the SMC to the LinkSys (lets just say, port 80). Then port forwarded Port 80 on the LinkSys to the PC. Same as the DMZ scenario above, but change DMZ with port forwarding. No dice, still :(. Now here's where I went stupid--and tell me if one should never do this--I enabled both DMZ and port forwarding at the same time. I fired up Opera--my browser of choice ;)--typed in 173.32.144.134:6333 and... ... Third time is the charm they say? Well, clearly not. Otherwise I wouldn't be here ;). To diagnose the problem, I enabled "Allow remote access to the Admin panel" on the LinkSys router, and specified port 6333 as the port to use. I port forwarded port 6333 on the SMC to 192.168.0.175, and access my external IP of 173.32.144.134:6333 in hopes of seeing the Admin panel... No dice (I think I've ran out of dice by now ;)). So to see where the problem was, I connected a laptop to the SMC via LAN cable, and typed in 192.168.0.175:6333, and viola, Admin Panel access! So the problem looks like it lies with the SMC--But that's as far as I've got, I've done the port forwarding, the DMZ'ing, and I've even disabled the built-in firewall for safe measures, but nothing worked. So, here I am. Unable to connect to the PC behind the Internal router externally, and without anything to go on other than to come here and ask for the wisdom of the the superuser folks :). If any more detail is required, just ask. (Apologies in advance, if questions should never be this long winded!)

  • WLAN adapter on Ubuntu Server inside Hyper-V

    - by Firefox333
    I need to set up an Ubuntu server as a router. However we need to make it wireless and wired. I need a WLAN adapter for the wireless part of the router. I get my Internet connection on my server through my wireless adapter from my host but it automatically sees it as an Ethernet adapter instead of as a wireless adapter. Is there any way of making a (virtual) wireless adapter on Ubuntu server 12.04 inside a hyper-v machine?

  • Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

    - by iyl
    I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

  • 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!

  • Network connection via USB

    - by Fco
    Can I get my Nexus One/Android on my local network over USB instead of WiFi and browse to my computer's IP address, the one to which the phone would be connected to, via USB? For instance, let's say my computer has an IP address 100.1.1.1 and when I go to it from the computer I would go to my localhost and see a website I've set up locally in the computer. Then, I connect my phone to that computer via USB. Can I then go to 100.1.1.1 from the browser and see the same website? All this through the USB, no WiFi?

  • Wrong Connection-specific DNS Suffix

    - by mydoghasworms
    I am on a Windows network with a Windows 7 machine. For some strange reason, when I run ipconfig, I see that I have the wrong DNS suffix for my network adapters, e.g. def.companyname.com as oppsed to abc.companyname.com. My colleagues next to me, who are on the same network, have the correct suffix. Where does the problem originate, and is it something I can fix on my machine (and if so, how?), or is this something a network administrator must resolve? (I did ipconfig /release and /renew, but that did not help).

  • My Router is fast when i reset it but slows down seconds later

    - by hglocke
    I have a Belkin N wireless router which until recently worked perfectly fine. Now i have to reset the router every few minutes, otherwise it slows down to a crawl. What can I do? I have tried turning the routers firewall off, but it does not make any difference. As far as I'm aware there have been no recent firmware updates. EDIT: The other devices on my network (laptop and iphone) do not have this problem. I connect to the router using a TP-Link wireless network card and I have already tried uninstalling and installing the driver. Hopefully this will narrow down the problem significantly.

  • wireless printer - entering WPA - is there a quicker way?

    - by camcam
    I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

  • Streaming a large file

    - by Rich
    quick question say i wanted to download a file of considerable size 10gb say and i sent the GET request to a web server to download that file question is, if the client stopped reading the TCP connection, would the entire file still be downloaded, or does it depend on the client sending back an ack or something to the circuit asking for the next packet hope that makes sense This question was originally asked involving the Tor network, but i just want to know how a standard internet connection would handle this Thanks

  • How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

    - by John
    I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

  • DHCP server can't see other machines

    - by William
    Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

  • CSMA between APs in same channel & different SSID ?

    - by Ranganathan
    Would be great if someone clarifies this doubt. Lets assume two Wireless Access Points AP1 & AP2 with these conditions 1. both in the same 802.11 standard 2. same channel 3. using different SSIDs (just like in adjacent apartment houses). In this case, do these two Access points (and the clients associated to them) coordinate via CSMA/CA ? ie., if one of the AP's or a client station is about to transmit, does it wait & observe the other AP's & its clients' transmission before sending the frame in air ? Also, do the clients associated with these different APs coordinate via CSMA/CA ?

  • How do I connect my Windows XP laptop to the internet?

    - by rubysiddhi
    Hello fellow super users, The Past I have a Acer Travelmate 2300 laptop running Windows XP. 6 months ago I moved into a new apartment and got a new internet connection set up. After getting an internet connection installed in my apartment I reinstalled Windows XP and at the same time wiped my drive clean losing all the original Acer software and drivers. Once XP was reinstalled I had to find all the drivers again to get the Travelmate laptop connected to the internet. So, using my Vista laptop which was connected fine, I went to the Acer Travelmate Series drivers download page to download the necessary drivers. I transferred them to my Acer XP machine and installed them the best I could (there were no easy instructions so I just had to find all the executables and run them). I eventually got connected to the internet but not exactly in the way I had hoped for. The Present To be connected to the internet I need to have an Ethernet cord connecting my computer (via the Ethernet port) to my router. This is a problem since it defeats the purpose of having a Wireless LAN card in my Acer laptop. One of the programs I downloaded from the Acer Travelmate Series page was the Acer Wireless LAN Configuration Utility. This program allows me to see the current network I am connected to and all the available networks I could potentially connect to. It reminds me of XP's Wireless Network Connection window/utility where you can see all available wireless networks, refresh the network list and connect to one of the networks. I should mention that my ISP set up a security enabled wireless network with WPA. This network requires a network key if you want to connect to it. I guess my Vista computer has the network key entered into it already. The problem is that I do not know what the network key is. Now obviously you would say just contact my ISP to get the key. And I will but there is just one extra weird issue. I am able to connect to another unsecured wireless network in the Wireless Network Connection window/utility. I can be on it as long as my Ethernet cable is plugged in. So this is not really wireless is it? And this indicates that even if I do get that network key password from my ISP, I will only solve one of the two problems I have. I will only solve being able to get online as long as I am connected to my router via the Ethernet cable. The Main Questions So how do I enable my acer IPN2220 Wireless LAN Card so that I can use my Acer laptop from anywhere with in my apartment? Or should I first get the network key from my ISP to access my security enabled wireless network? And then deal with getting the acer IPN2220 Wireless LAN Card working? Hard & Learned VS Easy & Stupid Of course contacting the ISP would be easier. Have em just come in here and do there thing. The problem with that is that they do not speak English (yeah, im in Poland) and it'd be a hell of a time trying to understand what they are doing (uncomfortable looking over their shoulder). Also, I want to learn how to do this task myself so that I can fix the problem if it ever happens again. You know, be more self sufficient. I look forward to helpful replies. Thanks, Xaviour

  • Preventing apps to access info from wifi device?

    - by heaosax
    Browsers like Chrome and Firefox can use my wifi device to get information about the surrounded APs and pin point my physical location using Google Location Services, I know these browser always ask for permissions to do this, and that these features can also be "turned off". But I was wondering if there's a better way to prevent ANY application to access this information from my wifi device. I don't like anyone on the internet knowing where I live, and I am worried some software could do the same as these browsers but without asking for permissions. I am using Ubuntu 10.04.

  • How to reduce the windows network browsing broadcast timeout or disable this function?

    - by Moi42
    Hello everyone. My residential network is make of 300 vlans (one per room). To browse them we are using a wins server. My problem is that when I try to browse the network, windows first tries to find the neighborhood using some broadcast, and only then does it query the wins server. This "broadcast period" lasts exactly 30 seconds and is very annoying. Can I reduce it, or can I completely disable this broadcast network discovery feature from my system? Thank you for your answers.

  • How do I install Skype on computer so that anyone who logs in does NOT have to go through the initial config?

    - by Matt
    I installed Skype when logged on to the (local) admin account. Now, when I log off that, and log on as myname on the domain, I have to click through the intial setup steps (after you've already run the installer) of Skype. So, I have to click next to get through the mic setup/test, and it asks me if I want to take a pic. How do I get it so that any person who logs in can just open Skype and go straight to the login screen? Windows 7 64 bit, 2008R2
