  • Identifying a CAT6 cable in a bundle

    - by Jon Tackabury
    We had a contractor wire up our office with all the cables leading back to a central location. The only problem is that he didn't label anything, so we have no idea which cables go to which room. One end of the cable is terminated in a wall-jack (in the rooms), the other end is un-terminated and will be punched to a patch panel. Is there a way to identify the cables without having to terminate them? We'd like to group the cables on the patch panel by room, but I don't want to crimp/punch each cable twice. Thanks!

  • What to do if people can't ping me?

    - by slayerIQ
    Today, I installed my new router so I can connect my other pc and my ps3. In my network, there are some other computers these are connected with each other through another router. So I have one modem with 2 routers that make up my network. Everything works fine the only problem I am having is being pinged by other computers in the network. All the computers are on the same subnet 255.255.255.0. There is no problem with my firewall or anything I tested everything. How can I solve this?

  • Windows XP SP3 dissapearing mapped drives

    - by Alan Spark
    I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

  • Problem creating ODBC connection to SQL Server 2008 with Vista

    - by earlz
    Well, I'm trying to get a database schema thing working, first I tried just doing it in Linux where I'm more comfortable, but ODBC seems to be a hack there and I couldn't get it to work. So I figured it shouldn't be too hard in Windows.. Ok, so I created a SQL Server Client Alias so that I can simply same windowsserver to refer to my SQL server. Then, I went to the ODBC configuration in Control Panel. I clicked Add in the User DSN section. I chose Native SQL Server (10), and then clicked next. Then I typed a short name and a description and gave the servername as windowsserver/SQLEXPRESS Then, I click next, give it my user name and password and click next. Then, after like 2 minutes it says "Login Timeout Expired" What can be wrong here? I know the server is configured cause I have SQL Server Management Studio opened up with that server in it. I'm also just trying to connect over regular TCP/IP and my firewall is disabled.

  • Network Bridging on Linux for OpenVPN

    - by Coyote
    I've been following all the OpenVPN Bridge tutorials I can, but I'm still missing something. Does anyone know of a super detailed tutorial\explanation of bridging? If anyone has bridging running, can I get a copy of your interfaces file to see how you've got it going. (Obviously change the ip address, just please change them consistently.)

  • 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.

  • Window 7 image in vmware will allow network connection out but not http

    - by Ormis
    I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I initially asked this on stackoverflow and now my eyes are now opened up to superuser. Thank you for any help you can provide.

  • Extremely poor WiFi reception on new desktop

    - by guy
    I just received a new desktop with a built-in WiFi card (Windows 7 Home Premium x64). However, I am only able to receive any WiFi signal when the computer is within 1-2 meters of a router. Even then, the signal is very weak (Windows 7 says it is "poor"). I have tried this with 2 different routers and see similar results. I have somewhere around a dozen other devices that can connect to both routers with greater signal strength (usually full strength) from much, much further away. When I tried calling support I was instructed to reinstall my drivers and attempt to change the WiFi channel of the router. Neither worked. I was then told that the problem was with my routers and that the computer was functioning normally and that it was certainly not a hardware problem. What would be the cause of this and is there anything I can do to fix it?

  • Everytime I ping my server, it is pinging localhost instead?

    - by esac
    I recently setup a new server for use with SQL. When I tried to connect via SSMS remotely, it failed. When I pinged it, it is pinging localhost, what is going on here?

  • Any consumer routers with Outgoing VPN support?

    - by Brian Lacy
    When I'm working at home, I need to be able to connect to three different outgoing VPNs, two of which happen to use the same internal IP addressing schemes (192.168.0.*). I also need a static address for my VirtualBox VM so I can connect to my testing web server. Are there any routers which will allow me to connect to multiple outgoing VPNs and assign different internal IP addresses through NAT? Is such a thing even possible, or are there alternate solutions available? Thanks!

  • Several border firewalls in the same network

    - by nimai
    I'm currently analyzing the consequences of multipath connections for the firewalls. In that context, I'm wondering if it's really uncommon to have several firewalls at the borders of a network to protect it. The typical case I'd imagine would be a multihomed network, for which the administrator would have different policies for links from different (or not) ISPs. Or maybe even in an ISP's network. What would be the practical (dis)advantages of such a configuration? Could you provide an example of an existing topology using several border firewalls?

  • Server needs to ping outgoing before allowing connection

    - by QuintenVK
    Okay, first our setup: I'm currently working over VPN to a mac mini OSX 10.6 server. We have a testsetup VM running on that, using ubuntu 12.04. Earlier today, there was an outage because of which our mac mini server was reset. Since then, i was unable to initiate a connection to the VM (which i did boot) -- no ssh, no web, ... . I couldn't ssh or web from the mac mini to the vm either. I could do so from within the VM itself, though. Ping did work on all machines. Lastly, I tried pinging from the VM to my laptop. It took a moment, but then it finally started to ping (no timeouts or so). After that, web and ssh magically worked. I then didn't use the machine for about 5 minutes, after which i had to ping from the server to my laptop again before i could setup a connection. I'm in the dark on what this could be, though I think this is something to do with lookups.

  • Download videos from youtube as I see it

    - by Sab
    This may seem a somewhat strange requirement : I want to download youtube videos as I see it. I know that I would have to capture the packets using a program like wireshark , and I do know that this is possible. So lets say I have 3 computers on my network and 1 smartphone. Lets say I view a youtube video on my phone. I now want this video to be recorded on any one of the computers so that I can see it later(record in the sense capture the packets so that I dont have to download it again and waste my bandwidth). Are there any programs which will do this for me? The reason I want this is I use IMediaShare to view youtube videos on my Tv. Now once I see a video if I want to see it at a later point of time I have to download the entire video again.

  • How to link processing power of old computers together?

    - by redIago
    Hey all, I'm sitting on 8 old computers of varied sorts that are more or less useless at this point for any other purpose really. Is there a way I could link their hardware or processing power or whatever together over wifi and use one as like a central computer? Like it would be cool to distribute the processing of some video game or encryption generating program over the collective computers. Any way to do all this? Thanks.

  • How do I configure IIS to allow access to network resources for PHP scripts?

    - by Dereleased
    I am currently working on a PHP front-end that joins together a series of applications running on separate servers; many of these applications generate files that I need access to, but these files (for various reasons) reside on their parent servers. If I, from the command line, issue a bit of script such as: <?php var_dump(glob("\\\\machine-name\\some\\share\\*")); I will get the full contents of that directory, proving that there's no problem programmatically with PHP reading the contents of a UNC share. However, if I try to execute the same script from the web server, I get an empty array -- more specifically, if I use more explicitly functions designed to "open" a directory like it was a file, I get access errors. I believe this to be a permissions issue, but I am not a server/network administrator type, so I'm not sure what I need to do to correct this and get my script running, and the links I've checked out have not been a terrible amount of help, perhaps due to my background, or lack thereof as far as IIS is concerned, coupled with the fact that we are not actually using .NET for this. Relevant Stats: Windows Server 2008 Standard SP2 IIS 7.0 PHP 5.2.9 I will be connecting to two types of servers: a few other nearly-identical Server 2008 machines, and a machine running embedded XP. Links that have not been particularly helpful but maybe I am just misreading: http://support.microsoft.com/?id=306158 http://support.microsoft.com/kb/207671/EN-US/ http://support.microsoft.com/kb/280383/

  • I have a wireless Canon P560 and my computer can't find it

    - by ed
    The printer is wireless and I haven't connected it via USB. I set the configurations for the Wi-Fi access point in the printer and it connected to my Wi-Fi. I have AT&T as the service provider and the 2Wire router. When I access the router in the browser I see that the printer is connected but when I run the software to detect the printer the computer can't find it. I have a Mac with Snow Leopard. I tried to detect the printer with another device and it can't find it. Is there a port that needs to be open for wireless printers? Because I tried putting the routers firewall settings for the device to its lowest and the computer still can't find it. Let me know. Thnx.

  • Windows mounted network drives slow after upgrading switch

    - by Kver
    On our small business network our old 10/100 consumer grade switch gave up the ghost, and we replaced it with a proper business-grade gigabyte switch. After wiring it in our Linux and Mac users immediately got back to working off of network drives; But 2 of our 3 Windows 7 PCs have suddenly experienced a tremendous slowdown with mapped network drives; Windows will become stuck "discovering" a folder causing applications to freeze when trying to open files. It will instantly display and browse files, but the moment you try to open one the bug hits. To remedy this we have our users copying files to the desktop, but it can take a few minutes while windows is stuck "calculating" the time it will take to copy. These aren't big files, mostly excel sheets less than 500KB - these operations are instant on Linux and Mac. (The third Windows machine is having no issues) I've tried remapping the drives, mapping to different drive letters, rebooting, etc. I'm at a loss, because switches are mostly transparent, and it's only after the switch was replaced that the Windows PCs started acting up. What black-magic voodoo am I missing to make Windows work? Thank you.

  • Lan DNS not working after reinstall of Ubuntu 13.10

    - by DrorCohen
    I upgrade my Ubuntu desktop to 13.10. When I say upgrade I mean installed on a new partition from scratch (old partition is available if To the problem: I'm trying to ping a host (Drobo-FS server) by it's host name. I get "Unknown Host". However pinging from another computer on the same lan - works fine (a laptop with 12.04 lts). for that matter every ping from the 13.10 to the local lan by hostname fails, ping with ip works. I don't have a local DNS server but somehow all the other computers in the network find each other by host name - only this new one fails... help appreciated...

  • Connect to a particular network connection from terminal

    - by RanRag
    I am currently using Reliance netconnect USB modem. The problem I am facing is my USB modem disconnects itself at 22:00 PM IST everyday. Now, sometimes what I do is start some downloading and leave my laptop for 2-3 hours in this case if my network disconnects it is a problem for me. So, what I used to do in windows is make a python script and execute rasdial myconnection_name to automate the connection process in my absence. Now I want to achieve something similar in linux. So, what are my alternatives for rasdial like tool in linux to automatically connect to a particular connection . I am using ubuntu 12.04 and here is my nm-tool output.

  • Windows 7 keeps asking for WIFI credentials

    - by RubenGeert
    If I want to log onto our WIFI network, Windows keeps asking for credentials. After many connection attempts (and sometimes some reboots) we finally manage to connect. Then the connection usually stays intact for the rest of the day. But it sometimes takes 15-20 minutes before we're online... Needless to say we're using a single username/password for all failing/succeeding attempts. Does anybody recognize these symptoms? How to troubleshoot this?

  • How to setup IP alias on bridged interface in Ubuntu

    - by Anonymouslemming
    How do I setup an IP alias on a bridge (br0) device on Ubuntu ? If I wait for br0 to come up and then do /sbin/ifconfig br0:0 192.168.10.1 netmask 255.255.255.0 then it works fine. If however I add the following to my /etc/network/interfaces file, it does not work and the network fails to start: auto br0:0 iface br0:0 inet static address 192.168.10.1 netmask 255.255.255.0 At the moment, I have a script in /etc/network/if-up.d/bridge_alias that does this as follows: #!/bin/bash if [ "${LOGICAL}" == "br0" ] && [ "${PHASE}" = "post-up" ]; then echo -n "Starting br0:0 ... " /sbin/ifconfig br0:0 192.168.10.2 netmask 255.255.255.0 echo "Done!" fi What is the right way of doing this though, just using the OS network config files ?

  • Examples of applications where messages are pushed from a server and display on clients immediately

    - by James Hay
    I'm trying to find an example to show where data is sent from a server and is pushed to a/multiple clients which are updated immediately, i.e. the client doesn't make requests for updates. It doesn't matter whether we're talking mobile, desktop or whatever. An even better example would be where there were multiple recipients for the same message. It doesn't matter what the data is or the context it's used in, only the immediacy of receiving it. I was thinking that there might be some example in finance and the stock markets, but I haven't been able to find any through googling. IM clients are a great example of this and are on my list of one ;) If anyone works on applications of this nature or knows of particular implementations, can you give me a quick run down of the use case and if it's commercial software the name of the software. This is all basically for research purposes so doesn't have to be particularly detailed. If anyone can help, thanks.
