  • What could cause a dual-monitor PC to suddenly stop using one of the screens?

    - by raldi
    I've got a dual-monitor setup using a GeForce 7900GT that was working fine for over a year... then suddenly, only one of the screens works. It's not OS-related, because even on startup, only one screen displays the BIOS checks. In the past, both screens would show it together. I didn't change anything to trigger this The monitor that gets a signal is random -- sometimes the one on the left goes black, sometimes the one on the right. The monitors and their cables are good -- I can switch both or either, and I get a signal just fine. They're plugged in, too. It's not the video card, either -- I have an identical 7900GT in another machine, and swapping the two didn't fix anything. It's not dust on the motherboard -- I pulled everything out, cleaned it off, checked for obvious damage, put it all back together, and no change. My next two steps are going to be to reset the CMOS info and to try swapping out the motherboard. Before I do that, does anyone have any other ideas?

  • Inexpensive (used) hardware for Xen virtualization test?

    - by Jason Antman
    Virtualization is one of the areas where I could really use some experience. I also run quite a few services (web, mail, dns, etc.) out of my home. Since most of my hardware is getting a bit old (I'm running on stuff that was surplused years ago...) I decided that it's about time I start renewing some things, and also play around with virtualization a bit more. My plan is to setup a SAN box (simple iSCSI target, relatively inexpensive gigE switch), get a pair (for starters) of new servers, and start building some new stuff with Xen, specifically planning on playing with live migration and full virtualization. Does anyone have recommendations for used, older "servers" (really anything in a rack-mount form factor, I'm not too worried about things like iLO/iLOM for the test nodes) that support VT-x/AMD-V? I'm biased to HP, but it looks like they didn't make Proliants with VT-x/Vanderpool processors until G6 (for the DL360) or so, which is way out of my price range. I'm looking in the sub-$300 range (or less, if possible), used, probably Ebay. Any recommendations are greatly appreciated. Edit:And, to catch this before the comments start coming - these are personal systems. I have first-generation Proliants still in use (I got them as corporate surplus in 05, they've been running since then, and probably were running since 01 or 02 prior to being sold). I don't need anything shiny and new - I've got a bunch of old boxes, at least one complete replacement for every model in use, and that's fine for me (and easy on the wallet).

  • Windows 8 Communication Sound Setting not working

    - by blackmastiff
    I've been having a problem on my new laptop recently which is familiar but baffling the usual fixes. I'm running Windows 8 with an onboard Realtek soundcard. It's similar to the one on my older computer running Windows 7. The problem is, when I'm in Skype or Mumble, Windows changes the sound output to lower everything else automatically. I've disabled the communications sound change option on the communications tab within sound devices and checked all the applications settings to insure that they are not responsible. They aren't, and I noticed something else. When I'm in the sound properties dialog, and I switch to the microphone tab, the same audio output reduction occurs. This seems to say to me that the microphone must be responsible in some way, but seeing as I uninstalled all the drivers and installed windows drivers instead, I'm confused as to why this would be occurring. Any thoughts? EDIT: I just tried disabling the built in microphone and the sound no longer get changed. More confused now? As soon as I turn it back on, the sound gets dropped again. Incidentally, the fix for this on windows 7 was this question: Windows 7 lowers applications' volume automatically I've got my computer set that way and it doesn't work.

  • Directory service unavailiable, new hardware same settings

    - by Alex
    I'm working on a project with 2 sites connected by a VPN. Site 1 has the main server and there is a secondary server at site 2 which I am trying to replace. The current setup works perfectly however I can't for the life of me get the replacement server at site 2 up and running. I'm trying to replace like for like just upgraded hardware. I have installed the OS (all Server 2003 Standard SP2) and used exactly the same settings as the old server. I have setup Active Directory, DNS Server, DHCP Server and WINS Server configured. I have used all the same settings as the old server (except IP address and name). I can access the active directory but I can't do anything; add, edit, delete all returns "the directory service is unavaliable". No-one can login on any of the computers on site 2 and the internet is down. Plugging the old server back in and connecting it to the network rectifies the issue (so both new and old are connected at site 2), everyone can login and the internet is back (curious since the modem connects direct to the switch, and even with the new server online I can connect to the router via IP but not the net). I really don't have much experience but I've been roped into doing this because my company is too cheap to hire a real network admin. Any suggestions of where I can start to troubleshoot this, its driving me crazy and I only have a day before all the users are back on site.

  • HP LaserJet 1515: Disable "refill" warning

    - by Pekka
    I have a HP LaserJet 1515 connected to a Windows 7 PC. The Magenta cartridge is empty; the printer shows a warning to that effect, and won't let me print even black-and-white documents any more. I can't turn the warning off manually using the printer's small console: When I try to enter any menu, the display says "Menu access disabled". I have no idea why. There is a setting to override the warning, but it can't be changed using the Network interface in the browser (Although it is there on the status page) According to the manual,the HP printing tool is supposed to offer a switch for this, but it won't install on my Windows 7. It just rumbles about for half an hour, to magnificently exit with an "unknown error" requiring a reboot. On second look, the problem seems to be that Windows 7 just isn't supported. There is no download link for the tool when you specify Windows 7 as your OS. I just want to print a black-and-white-document on a printer whose black cartridge is still 65% full. Is this indeed impossible? On second thought, I'm cross-posting this on the HP support forum. I'll update here if anything comes up.

  • Screen recording in Windows 8 makes PC unusable?

    - by Skadier
    OS used: Windows 8 Pro x64 Hi there, I got a weird problem. I tried to record my screen using different screen recording applications like Camtasia7, Hypercam, and some others. So if I hit "record" everything works fine for about 3-4 seconds. Then the PC slows down heavily caused by extremly high IO usage. The PC gets nearly unusable and laggs like hell. I can't switch applications, can't get TaskManager with Ctrl+Alt+Del, or something else without waiting 1-3 Minutes. After about 5-8 Minutes and a bit of luck I am sometimes able to end the process of the recorder and IO calms down very slow(100% IO lasts for about 2 Minutes before becoming normal). I don't know why this happens. Screen recorders that support Windows 8 aren't out afaik but at least Camtasia7 worked with Windows 8 Developer Preview and Windows 8 Release Preview (only had to change record method to .avi). No slow downs or something else. Is there anyone out there who knows this problem too? Is there maybe a solution to this problem?

  • Will the removal of NAT (with the use of IPv6) be bad for consumers? [closed]

    - by Jonathan.
    Possible Duplicate: How will IPv6 impact everyday users? (World IPv6 Day) As I understand when we have finally made the switch to IPv6 not only will NAT be unnecessary but it is incompatible with IPv6? Will that mean that ISPs will have to serve multiple IP addresses per customer? Will they provide a range of addresses for each customer or as each device connects will they get an IP address that isn't necessarily near that of the other devices in their house? But overall will this be bad for the Internet users? as surely it will allow ISPs to see exactly how many devices are being used, and so allow them to charge for the use of additional IP addresses? And then if that happens, what happens when you try to connect an extra device to your network? Will it simply not get an IP address? In my home we have about 15-20 devices connected at once, but for places where there are hundreds of devices, it seems like the perfect opportunity for ISPs to charge more? I think I may have it completely wrong, so is there somewhere where there is an explanation of who things will work when IPv6 becomes the norm?

  • Computer Turns on Briefly then right back off again.

    - by goddamnyouryan
    So yesterday I came home from work and went to turn my computer on....it turned on for about 5 seconds then promptly turned right back off again...before I ever saw anything on the screen. I tried again, same result. After several attempts, I've found that the length at which it turns on differs. After trying multiple times in a row, it only stays on for about 3 seconds. If I let it rest for a bit it sometimes will stay on for up to a minute (though it never boots, the screen stays black the whole time). I'm not sure what is causing this issue...I built this computer a little more than 2 years ago and this is the first issue I have ever had with it. I did all the usual checks: -It's not the power switch -The capacitors on the motherboard all seem to be in working order -The PSU seems to be fine as it lights up, fan spins, and will sometimes stay on for about a minute period My hope is that the thermal paste on the cpu has degraded and just needs to be re-applied. Does that seem like a reasonable assumption? I'm going to tear the thing apart and do a minimum system build when I get home, but any heads up as to what I should be looking for would be much appreciated. Any thoughts?

  • I have just created a subnet for a local network, connecting to a standalone server on another network, now I cannot connect to the internet

    - by Seth
    I am just learning some new aspects of servers and networking. We have a network of 5 subnets that all interconnect with each-other. In order to get two computers on the subnet that we were setting up, I changed the IP from the subnet where the standalone server is on (where they used to be set up)to the local subnet we are remotely hooking up. Likewise I also changed the gateway to coincide with the new subnet. Only problem is that since doing this, I am unable to establish a connection to the internet. I can ping the server and correspong gateway & DNS server, but cannot get connected to the internet. We do have a dumb-switch (non-programmable) connected that receives both the internet and private network inputs and distributes (or should do so) to about 5 other computers. Bottom line, I cannot currently connect to the internet, and am wondering what could be causing this.. It is likely something very obvious and pardon me being more vague than I probably should be, but I could use some help resolving this! Thanks for any help!

  • How can I assign DHCP leases from a script?

    - by devicenull
    I have an environment where there is one DHCP server servicing a number of different hosts/vlans. The switches are configured to forward the DHCP requests over (via ip-helper) and include information about the port (option 82). I'd like to take that information and translate it into an actual lease for the server. I don't think it's particularly feasible for me to pregenerate a list of available leases, but I should be able to determine an address for a lease as it comes in. Is there an DHCP server that can execute a script when it receives a request? (Note: I'm looking to assign the IP from the script, not have the DHCP server assign an IP then execute the script) Edit: So, ultimately I'm trying to provide DHCP/PXE services over a large number of distinct vlans. This is so we can do OS installs via PXE booting without having to have a separate PXE vlan. I've got the switch config down no problem, and I have the DHCP server recognizing option 82. I need a way to pull DHCP assignments from another system (this other system would know what subnet to use on what vlan), but I do not want to have to pregenerate a list of vlan:DHCP range pairs.

  • Linux 'top' utility widly inaccurate (more so for multi-CPU/core hardware)?

    - by amn
    Hi all. After using 'top' for long time, albeit basically, I have grown to distrust it's '% CPU' column reports. I have a 8-core (quad core Intel i7 920 with hyperthreading) hardware, and see some wild numbers when running a process that should not use more than 5% overall. top happily reports 50%, and I suspect it is not so. My question is, is it a known fact that it's inaccurate when several CPUs/cores are present? I used 'mpstat' from the 'sysstat' package, and it's showings are much more conservative, certainly within my expectations. I did press '1' for 'top' to switch it to show all the core and us/sy/io stats, but the numbers are substantially higher than with 'mpstat'... I know that my expectations can be unfound as well, but my gut feeling tells me 'top' is wrong! :-) The reason I need to know is because the process I am monitoring only guarantees quality of service with CPU usage "less than 80%" (however vague that sounds), and I need to know how much headroom I have left. It's a streaming server.

  • oracle access on vmware fusion

    - by gaudi_br
    Hello, I'm running snow leopard and I'm doing some development that requires some network knowledge. I've installed vmware fusion 3.0 and I've set up a virtual machine with windows 2003 server. I need to mimic the exact configuration of another server in the network, so I really need to run the versions I'll be mentioning here. Besides, I set up two network configurations on the VM: one NAT config (so that I can have internet access) and one host-only config (because I need to use another server's mac adress and my local area network might have a problem with it) From the installation of windows 2003, I then installed oracle 10.2.0.1. During the installation I received a warning about the primary ip-address of the system being dhcp assigned, but I ignored it (maybe it was a mistake)... Now, from experience, unless the DHCP assigned address changes, I should be able to access the guest system's database from the host system, so I went to safari and tried to access the oracle em. As it turns out, because my computer is on a company network, the company's DNS doesn't know about the virtual machine, unless of course I switch to a bridged network config. However, I don't want to do that because I don't to mix up the domains. So I guess the question is, how can I define my own dns or router, or whatever it is that I need to define so that whenever I try the guest system's ip address form the host, it will use the vmnet1 or vmnet8 interface define by vmware and bypass the dns configuration of my local area network. I'd also like to know what to do incase I want to change ip addresses on the guest machine without having oracle go haywire (I've noticed a few folders on the structure which are specific for the very first IP Address)... Any help would be appreciated. Thanks in advance.

  • Where does Firefox store cerificates and how to delete one?

    - by majid4466
    Hi all, The root cause of my problem is not known to me, whatever it is, I experience frequent DNS failures. When it happens I cannot browse to my Gmail inbox. I use two DNS settings. One is the public DNS server offered by OpenDNS, and the other is Google's free DNS server. When this happens I switch from the active setting to the other one and the problem goes away. But there is a side effect to this. When browsing to Gmail fails to load, after switching the DNS I receive an error saying the security certificate the site uses is only valid for OpenDNS. This my wild guess at what is going on: OpenDNS fails to resolve mail.google.com to its IP, My ISP sends me a page showing search results for 'mail.google.com' Since I have received some sort of page instead of a timeout, the browser, mistakenly, binds the certificate it has cached for 'mail.google.com' to the new domain. This search page is not served by https so not exception is thrown by the wrong binding After switching the DNS, the domain is correctly resolved to Gmail server's IP and since his is on https the handshake is triggered. Now, because of the wrong binding, which passed quietly as no handshake was involved, I receive the error saying the certificate used by 'mail.google.com' is only good for openDNS I don't know much about DNS, less about https and the process of establishing a secure connection. How correct is my explanation? How can I delete the wrong association and/or the certificate? Thanks for listening. P. S. The problem goes away by itself, but sometimes it takes several hours before Gmail works again.

  • Nginx and 1000 WordPress Installs - Optimization

    - by GTE
    Hey, I'm trying to create a rather unusual (imo) configuration where I have: nginx php-fastcgi mysql 1000 seperate WordPress installs (with WP Super Cache). Each WP install corresponds to a seperate subdomain. Furthermore, I have 1000 cron jobs being called every hour that in turn call a WP plugin (using wget) which retrieves data from an API and posts it to the respective blog. This is all being run on a virtual server with 1024MB of RAM, 4 shared processors, etc. The server is not doing well, especially during the times that the cron jobs are being executed. Nginx constantly throws 504 errors and the site has a significant lag. 1) Am I crazy for having 1000 individual WP installs? Should I be using WP-MU and will this help significantly? (I have certain plugin restrictions that I prefer having seperate installs but could switch if need be.) 2) Instead of having 1000 unique cron jobs - should be calling say a bash script that will then process the 1000 HTTP requests I need? Could this be done in a succesive order instead of a sequential one? 3) Any other kind of suggestion you may have for optimization? Should I be proxying to Apache instead of just using nginx, etc. Any kind of advice would be appreciated. Thanks in advance

  • Is it possible to automate a driver change on Windows for a plug&play peripheral ?

    - by Gnoupi
    Is it possible to automate a change of driver for a same peripheral, under Windows ? Typically to switch between two ones. (I'm talking about the kind of driver which doesn't require the computer to reboot, typically). I have a peripheral for which I use the constructor's driver in some cases, but also a modified driver in other cases. Not that the changing driver is really annoying, but I would like to know if it would be possible to make it easier, like for example in a shortcut. I know the name of the driver, even which files involved. For more details, the concerned peripheral is a "Xbox360 Gamepad for Windows" (or something like this). The base driver is good for new games, but it doesn't handle correctly older ones (some issues with axes, and vibrations). The modified driver makes it behave like a classic controller, but then it doesn't work correctly on new games (typically using the new version of dxinput linked to the "Games for Windows"). However, this is not a question specific to this gamepad, I'm asking in general about automating this change of drivers. I currently use Windows XP, so my question is mostly about it, but I'm also interested in the same issue for later versions (Windows 7, most likely). I'm not really sure if this is even possible, but in case someone has an idea, I'm asking.

  • Map Subdomains to Folders Owned/Run by Other Apache/PHP/Cpanel Users

    - by kristofferR
    I run a small service for Norwegian customers where they get automatically installed and configured Wordpress blogs on their own domains ready immediately after payment is finished. It's quite similar to Page.ly and WPEngine, just aimed at Norwegian customers with Norwegian Wordpress, support, billing etc. The backend is WHM/CPanel (Apache, PHP, mySQL), with a script running immediately after payment that installs and configures Wordpress and sends the customer an email with their username and password. Newly registered domains takes some time to propagate though, so for a day or two my customers unfortunately have to use a temporary URL before I can switch them over to their own domains. Right now my system uses mod_userdir ("serverIP/~cpanelusername"). However, it's not an optimal solution. It looks unprofessional, is confusing, and is quite problematic for both my customers and me. I'd rather prefer the temporary URL for their blogs to be "theirdomainwithoutextension.host.no", with "host.no" being a domain I own and served from the same server as the customer sites. I can easily modify the script to create the subdomains on my "host.no"-domain, but how can I seamlessly map the subdomains to folders owned/ran on/by different CPanel/Apache/PHP users?

  • How do I disable DirectDraw and Direct3D acceleration on Windows 8? [closed]

    - by Favourite Chigozie Onwuemene
    Some old games that i would really like to play run slowly on some graphic drivers when direct3d acceleration is enabled. I have tried many suggestions but none seems to work. The only thing i have not tried is disabling direct3d acceleration. Is it possible to disable DirectDraw and Direct3D acceleration on my Windows 8 pc? There are certain bad versions of GeForce drivers that cause this problem. This is a problem in the drivers themselves and is unfortunately completely outside our control. The recommended way to fix this problem is to update your graphics card drivers (go to NVIDIA's web site for this). Alternatively, there is a workaround that alleviates or solves the slowdown problem altogether. Try this: Right-click on your desktop and select "Properties". Go to the "Settings" tab and click on "Advanced...". Click on the "Troubleshooting" tab and move the slider to the left until it says that all DirectDraw and Direct3D accelerations have been disabled (around the middle of the range). Finally, click on "OK". Note that this workaround might cause other games on your computer to slow down, so you may have to switch back and forth between settings, but it's certainly worth a try if you can't obtain an updated graphics driver. -source: interactionstudios

  • Some pages begin to load and stop on Chrome

    - by corsiKa
    I'm using Chrome (Version 22.0.1229.94). About 20% of pages simply stop loading after a second or two. Sometimes, I'm able to click an early link after a second or third reload. If I attempt to close the page, it continues to hang for a few (10-30) additional seconds, then closes. However, if I switch to other tabs, it works just fine. If I don't change tabs and wait long enough, it says that there's something on the page that's taking too long to run and offers to let me kill it. Only a select number of sites fail to load, and they do so consistently. None of the stackexchange sites or google fail, but others like realclearpolitics and wowwiki do. I visit those sites every day, and this is the first time it has failed like this. If it were just one site, I would say someone messed something up in their deployment. But it seems incredibly peculiar that suddenly, half a dozen popular sites all mysteriously have the same symptoms. If I attempt to load the pages in Firefox or IE9, they load just fine. Nothing new has been installed, regarding Chrome or otherwise. Antivirus reports no abnormalities. System is regularly patched. Restarting both chrome and the computer have had no effect.

  • WebSphere hung threads, how can I track then down?

    - by Puzzled
    We have an application running on WebSphere (unfortunately it is 6.1 which is no longer supported, it has not yet been migrated in production to a later version) which becomes entirely unresponsive because of hung threads. As far as I can tell we entirely exhaust one of the thread pools. I have activated hung thread detection and I get a core/thread dump when hung threads are detected. The server can run for several days without problems but has crashed twice this week. When load the core/thread dump in "IBM Thread and Monitor Dump Analyzer for Java", it tells me that there are a certain number of hung threads (this time it was 2, last time 11) and multiple (usually around 40) threads "waiting on condition" and some running threads. I believe one of the thread pool has around that size (50). Now what I see in there are threads waiting for locks, having locks or in wait. Most of them show a stack track which always ends like this: at java/lang/Object.wait(Native Method) at java/lang/Object.wait(Object.java:231) Now, how can I track this down to either a server configuration problem, application issue, WebSphere problem or something else? How is this supposed to help me track down the problem when almost everything in there refers to IBM code? I cannot ask IBM's help as 6.1 is now an unsupported version of WebSphere and while work has been done to make it work under WebSphere 7 we are not yet ready to switch to it in Production yet.

  • Allow more websocket connections

    - by Switz
    I want to load balance my node.js (DerbyJS to be specific) application on a basic Linode (512MB ram). It can probably take more than one process running at once. The querys/database does not concern me as I'm not doing anything intensive. The problem at the moment is that it can only handle up to ~40 websocket connections at once. I would love if I could get that number in the few hundred+ range. I anticipate a lot of traffic on launch due to the fact that it's a highly niche community with an engaged audience, but after it should be fine with just ~20-40 connections at once, which it handles perfectly as of now. I don't mind spending a bit of money for a week or two worth of running, but I also don't want to switch production environments. How can I test the process to see how many instances I am able to run on the box? Will increasing the number of processes increase the amount of websockets I can handle, or is that a limitation of the server's network? I have an old Macbook Pro running Linux sitting next to me that has 2GB ram and a 2.8 Dual Core Processor. Could I use this to handle some of the extra load? I could probably load balance with nginx to its IP. I'm on a FiOS home network. If you have any suggestions, I'd really appreciate it. Thanks

  • Internet keeps connecting and disconnecting

    - by OmerPT
    I have a PC running 32bit Windows 7 Professional. My wireless internet card is Edimax EW-7128G, it is inside my computer case and it is connected to an antenna. My problem is: I have a wireless connection to my router, the signal is fine and it's not slow or anything, but it just keeps disconnecting every 30 seconds or so, then connects back, then it disconnects, then connects back and so on. This is new - it only started about a week ago, everything worked just fine until then. I know it's not a problem with the router because: Other computers can connect to it easily and they work just fine, no disconnections (My phone too). I know it's not a problem with the computer or the wireless card itself because: I have Ubuntu installed side-by-side with my Windows, and when I switch to Ubuntu the internet works great. This caused me to think it's probably a problem with the wireless card drivers installed on windows (Ubuntu auto-installed them, I installed them manually on windows): I tried uninstalling them, and then installing them back again, sadly that didn't help. I'm kind of lost here - can anyone think of anything else I should try? Thanks :)

  • VLAN across a router to give wireless access to remote sites?

    - by Don
    I've been looking online for this answer, but getting conflicting information. I was under the impression that you couldn't use a VLAN across a router, but maybe it's possible (according to some documentation I see online)? I was hoping someone could clear it up for me. Here's what I'm working with: We have a remote site with a handful of users. We recently gave them an access point (Cisco 1142n) for internal wireless. It's plugged into a switch and working fine (getting IPs from the same DHCP scope as the wired users are getting). Private wireless is set on VL50. At the home office we have private wireless for our internal network working and on VL50, with a test VLAN setup for VL60, which points to our DSL line for the time being. Both private and public wireless works fine internally (not crossing a router). VL50 is named the same at both sites for consistency in naming. If we wanted to give the remote site access to the public wireless (VL60), would that be possible across the routers? For more information, currently the site is connected to the home office via a T1 connection, Cisco routers on both ends. I didn't think it was possible due to the nature of VLANS being layer 2. But, I am from from an expert on this and would appreciate any instruction as to the actual truth of the matter. The end result I'm going for is, how to get our remote sites access to a public (outside) connection along with their private connection, without actually having a DSL (or similar type line) dropped at their location? Thanks in advance for your thoughts.

  • what is best multi-server configuration with OpenVPN

    - by sebut
    We have a number of Database severs running MongoDB on Debian plus a number of Application servers also on Debian. The db servers hold replicating db clusters, so they need to talk to each other. Application servers need to talk to all db servers (for reasons of fault tolerance). The servers are potentially spread across multiple hosting centers, so we need secure channels between all servers. The number of servers is bound to grow, so we need a VPN solution that's easy to maintain and expand. This is why I feel that SSH that we use for testing might not be up to the task and OpenVPN seems the way to go. I have ruled out TAP, since I understand that this would mean all traffic going to all the servers - perhaps this is a misunderstanding and TAP acts more like a switch? With TUN devices I imagine that all DB servers would live in their own separate subnet, they would also need a client configured to be able to connect to each of their peers. The application servers could live in a common subnet range with a client config only. Does this sound like a reasonable setup? Strangely, on the web I did not find anything about multi-server with OpenVPN. Thanks for all insights and ideas!

  • Looking for a nice and handy bandwidth limiter

    - by Spirit
    Here's the thing. My ISP are f*gs. Most of the time the network is realy good, but then again there are times when it sucks. They say we have 20mbp/s. Me and my brother are usually playing dota and it's fine. One of us plays the other's watching streaming or both of us are playing or something like that. But sometimes like one of these days one is lagging even if the other is watching youtube at 360p quality. So I do know that there are many bandwidth limiters out there. But what could you recommend given my situation. I like both of us to be able to install it and it would be good idea to have something like ON/OFF switch. When he is not here I would like to turn that thing off. But when one of us plays I would like to turn it ON and whatever I do, to be limited to 10 or 8mbps. That way we will not interrupt each other. Thanks guys :)
