  • Laptop with Windows 7 turns on spontaneously while being in "Sleep" state

    - by alexb
    I own a laptop(HP Pavilion DV7) with Windows 7 installed for already half a year. Usually when I finish my work I do not turn machine off - closing is enough to get is into "Sleep" state. Generally it's okay for me, but recent several days laptop was turning on in night spontaneously, while I was sleeping. I haven't installed any app with "turn-on by schedule on when_dooes_pc_wants"-like features. Checked if there are some "Wake-On-Lan"-like settings in BIOS, haven't found ones. The power-cable is always plugged-in. Does someone have any suggestions regarding that? p.s. laptop is placed right near by bed, so when it turns-on on night - it is quite annoying and a bit scary. I think it's trolling me, please help to stop it :) Thanks.

  • Samsung TV connected to PC for Powerpoint

    - by Skaughty
    I have a 42" Samsung LCD TV connected to a Dell computer with a PCI Radion 9000 via a 35' VGA cable. It's purpose is to run power point presentations over the TV for our retail store. I have tried every combination of button clicking on the video card options, and everything on the TV, and I still get black bars on the top and bottom of the image. It looks like I am watching a old wide screen movie on a full screen TV. The TV's suggested resolution is 1024x768, and that is what the output is set to. I have tried this with a nVida PCI card as well with the same results.

  • Configure PL2303-based USB-to-RS232 adapter to stay awake when no active device is present

    - by casualuser
    I am resurrecting some X10 devices with the aid of a USB-to-RS232 adapter. The problem is, that the adapter only works with the Firecracker device when there is another serial device on the line (the Firecracker is a pass-through device that monitors the RTS and DTR lines to do its magic). Is the PL2303 going to sleep without a real device on the line? Is there an option or command to keep it awake? Is there a cable configuration that would make it work without a real serial device present?

  • Database for heat tolerances of various cables?

    - by I. F.
    Is there any kind of unified database of heat tolerances for networking cables? I've been setting up a number of home/small office networks lately and as a mostly-amateur I could really use some information on what is safe to run behind a radiator, next to a steam pipe, etc. The question I'm up against at the moment is: Can I run normal RJ11 phone line cable (from DSL modem to phone jack) behind a steam radiator without risking a fire? Unlike cat5, I could not find published standards for these, so I'm turning to experts with more experience. This is a cut-rate show. Do I go out and buy more cabling, and if so which, or use the spare that I have?

  • Infected Win XP disk not openable on a Vista computer

    - by Retired57
    How can I read a WinXP partioned disk that is infected and shows up on a USB connection to Win Vista computer as a single partition that Vista cannot see the contents? The XP computer HDD is partioned into 4 partitions. It became infected, and all attempts to clean it have failed. Applications begin to launch, but are then shut down by the infecting agent. Using a major Anti-virus Co. boot disk (which was unable to connect to the Web, probably because the infecting agent stopped it) with virus definitions dated after the disk became infected, the resultant scan showed no infection. I bought a USB cable to connect the IDE drive to my Vista computer, but when I open Win Explorer, it sees the disk, but does not show any contents. It indicates it is a single partition that is valid. However in all the ways I have tried it does not show drive contents. Any suggestions on what to do next?

  • Cannot install windows. Compaq Presario CQ62

    - by Matthew
    I bought a used Compaq Presario CQ62 for cheap, and went to install windows on it. I formatted the partition and went to install when I got this error.... Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error code: 0x80070017 I have used this disk before with no problems, but internet searching suggested I burn one at 2x speed because that helps for some reason... I'm burning one now, but my question is, why would I get this error, OTHER than the disc being bad? I'm pretty certain this one isn't as I have used it before... (ok so the slowly burned cd (using imgburn) didn't work either so it's DEFINITELY not the disc) Thanks in advanced for any answers Also I took one stick of ram out because internet searching also suggested that, but it didn't make a difference. Also I ran memory and hard drive checks and they passed fine. Also I reset the motherboard options to default What could it be!? Help I'm completely stumped...

  • How do I record sound from my CD/DVD player without other system sounds in the mix?

    - by Software Monkey
    Using GoldWave I can record via the "Stereo Mix" channel, but I get no sound on the "CD" channel. Of course, using the stereo mix also mixes in all system sounds, including beeps, etc. I have the analog out on the DVD player connected to the CD-IN connector on the MoBo. I can hear CDs and DVDs playing just fine through my speakers - is this because the CD is also IDE data connection in to deliver the sound to the sound card, then? I specifically want to record a DVD; I can easily rip a CD using GoldWave's built-in ripper. Is there anything I have forgotten or have to enable? Or is it likely I have a damaged cable? My system is an MSI mobo and is running Windows XP SP3.

  • Linux as a gateway (no NAT)

    - by Hugo
    I'm trying to configure a linux server as a gateway/router, but I can't get it to work, and all information I've managed to find is NAT-related. I have a public IP block for the gateway and devices behind it, so I want the gateway to simply route packets to the internet - again: no NATing! I've managed to get the gateway to access the internet successfully (that was just a matter of configuring the IP and GW), and the computers behind it can communicate with it. [EDIT: more info] This is actually an IPv6 block (2800:40:403::0/48) (but I've found that most utilities and instructions can be easily adapted from IPv4 to IPv6 with little hastle). The server has too ports: wan: 2800:40:403::1/48 lan: 2800:40:403::3/48 One of the computers behind it is connected to it via a switch; 2800:40:403::7/48 The wan interface on the server can ping6 www.google.com without issues. The lan interface on the server and the client can mutually ping each other without issues (as well as SSH, etc). I've tried setting the server as a default gateway for the client, with no luck: client # route -A inet6 add default gw 2800:40:403::3 dev eth1 server # cat /proc/sys/net/ipv6/conf/all/forwarding 1 I don't want any filtering/firewalling/etc, just plain routing. Thanks.

  • I just got a virus 6 mins ago, how? Situation.

    - by acidzombie24
    -Edit- for the people who say it isn't a virus. Norton does detect it as a virus, an icon was placed on my system tray and rkpg.exe is in my C: which was placed 6 min ago around the time my computer rebooted on its own causing me to lose data :@. Situation I on Windows XP, behind a Linksys router, I don't have DMZ on so nothing should be connecting to me. I had Firefox, MSN and Visual Studio opened. With C# I programmed a quick application to scan some pages with Internet Explorer. The site it was scanning was deviantART (which is pretty trustworthy), I doubt any banners there would hold a virus. I went to a suspicious site called freetxt.com but that was on Firefox and it didn't load the site. With an extra check I ping it and got this message "Ping request could not find host freetxt.com." The virus seems to be called braviax. Right now it brought up a message saying my computer may be infected? How on earth did it get in? I don't have uTorrent installed or any torrent or p2p applications. Nothing is installed on my computer that I haven't installed before and I know the exact time it installed because I see rkpg.exe on my C drive and my computer restarted on its own around the same time. For the previous 30 minutes actually the previous hour all I did was talk on MSN, not click any links (I went to freetxt on my own) and had that Internet Explorer thing running (which I programmed). How did it get in? I really doubt it came from a banner on deviantART and installed when I loaded the page with the webbrowser-control so something else may have happened? Is there any system defaults I should turn off? I have remote assistance off but even if it was on I shouldn't be infected due to the router not forwarding any ports?

  • DNS point to server on ISP and keep shared host too?

    - by Dwayne
    I know this is probably quite easy to do, but I might just have the right search sorted out... so here is the situation: We have example.com set up as a hosted server along with app1.example.com, app2.example.com and a few others. What I would like to do is set up the right zone file to also make our internal server addressable from the outside world as internalapp.example.com. This server sits behind a firewall (pfsense) and is hooked up to the world via a cable modem that is technically on DHCP from our ISP, but has had the same external IP for the past 15 months so far. What would be the best way to set this up?

  • Connecting to network device behind NAT from local LAN using the external port and IP

    - by lumbric
    I noticed at several different LANs connected to the Internet through a NAT the following phenomena. There is a server in the LAN and there is a port forwarding to reach this server also from outside the LAN through the NAT. E.g. consider a LAN with the address 192.168.0.* and a SSH server at 192.168.0.2 with port 22 and a forwarding from port 2222 at the NAT 192.168.0.1 to 192.168.0.2:22. If the NAT's external IP is 44.33.22.11, one can connect to the SSH server through 44.33.22.11:2222. Surprisingly this works only from outside the LAN. If one tries to connect to 44.33.22.11:2222 from behind the NAT, there is no answer. Of course one could simply use 192.168.0.2:22, but often it is simpler to use the external IP. The typical use case for me is the configuration on a laptop computer. Usually the user uses any arbitrary Internet connection to connect to his home or office server, but sometimes he will use also the LAN to connect to it and it would be annoying to have to different configurations or bookmarks. Why does it fail to connect from inside the LAN? Is there any good work around?

  • Nagios: Is it possible to have multiple IPs for a host?

    - by Aknosis
    In our office we have dual WAN setup, if our cable connection drops we still get connectivity via our T1. The only issue is that our office network is no longer available on the same IP so all Nagios check go critical because they can't connect. What'd be awesome is if I could have Nagios try IP 1 by default but if for some reason its failing on that IP try IP 2. I doubt this is possible with a default install but I'm wondering if there is any add-ons or some other magic that could make this work?

  • exchange server 2010 with multiple domains

    - by air
    i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server. Thanks

  • Planning office network [closed]

    - by gakhov
    I'm planning to setup my office network from scratch and want to ask professional opinions or tips. My office is connected to Internet with Cable connection (100Mb/s). The devices i would like to connect are VoIP Phone (RJ-11), TV (WiFi/LAN), 3 laptops (WiFi), a few smartphones (WiFi), iPad (WiFi), Kindle (WiFi) and, probably, MediaServer (WiFi/LAN). As you can see, the most load will be on WiFi connections (probably, even if TV supports WiFi it's better to connect it by LAN?). So, i need help to choose the best routers combination (or even one?) to support stable connections for all these devices and minimize the total number of routers/adapters. Any thoughts? Thank you!

  • VPN: Disable class based route addition for Windows XP/Vista

    - by brgsousa
    Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

  • plugging in a 3.3V 50pin laptop HDD to USB?

    - by barlop
    I have a 50pin laptop hard drive. 1.8" wide. This 50pin connector concerns me.. Even if I get an adaptor, How can I know which side of the connector takes the power? I don't want to plug it in the wrong way. And I don't have n adaptor.. Could people link me to adaptors too. but main question is, which side to plug it in when I get the adaptor. I want to be sure. I do not want to blow the hdd. For the 3.3V I have a plan. Connecting green and black and using the orange cable(3.3v) to feed power. I am not too worried about that bit. But as I said.. Main thing is I want to know which side is 3.3V hard drive is MK6006GAH

  • Two network adapters in one WindowsXP PC, how to make them work?

    - by Deele
    I have a need to set up network so I can use two ethernet cards inside one Windows (Windows XP SP2) based PC, one for internet connection, second, for internal LAN. How should I configure each NIC, with what IP's, subnet masks and gateways, so I can use inernet on my PC and get in touch with devices on my LAN? I have found that there are some sort of re routing nessesary inside my PC, but how does it work? I have already set up some configuration already, but I can't use it together with PC #1 NIC #1 connected. I need to disconnect, to access NIC WEB interface. Current configuration: Switch #1 and PC #1 NAS #2 are gigabit one's, so I could access NAS with gigabit speed. PC #1 NIC #1 IP XX.XXX.162.106 SN 255.255.255.248 GW XX.XXX.162.105 PC #1 NIC #2 IP 10.0.0.1 SN 255.255.0.0 GW 0.0.0.0 NAS #1 NIC #1 IP 10.0.0.12 SN 255.255.0.0 GW 0.0.0.0 My question is - what exact configuration should I do for every NIC in this LAN, so it would work? Is it possible to achieve internet access for Laptop, that is inside that NIC #2 LAN (should I just set up basic ICS)?

  • Network bandwidth usage dashboard?

    - by SkippyFlipjack
    I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

  • Broken screen on laptop?

    - by John
    I recently damaged the screen on my HP Notebook...now my main concern is that I have Roboform installed and on my taskbar. The trouble is, because the screen is totaled, I can't see anything, and I discovered, to my horror, that I haven't backed any of the IDs and passwords up to a text document. Of course, I cannot access any of my content that hosts an ID name and password at all unless I can access Roboform that is installed on the notebook! Now hopefully I have ordered a SATA/USB cable to access the hard drive that I now removed form the notebook will I be able to access roboform that way and ALL the log-in details?

  • Window 7 not recognizing printer for driver (re)installation

    - by user55406
    OK I am having this printer problem. I had a user delete her printer. Please don't ask, I don't know. She is using an HP deskjet 6940 printer, and for her desktop she has an HP dx2400, with Windows 7. When I plug in the USB cable it should install the new drivers, but it does not. I believe you guys don't need to know my network setup. I could be wrong. If you guys here at serverfault could help that will be great. :)

  • How can I disrupt my roommate's BitTorrent?

    - by bob
    We're on a 50 mb/s Comcast connection and our connection right now is coming in under 1.5 mb/s. Our roommate left for a week with BitTorrent running (Azureus client, we think). Our latency is approaching 300 ms. His door is locked up tight, and both his machine and the router for the house are located inside. I've even flipped the power breaker in the house and that barely works for 2 minutes. His laptop keeps on running, and once the cable modem and router come back up and the machine reconnects, the torrents resume in earnest. I've been running nmap and identified his IP on our LAN. Is there anything I can do over the LAN to make his torrents start to fail or slow down?

  • System With Two Network Adapters [closed]

    - by Synetech inc.
    Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

  • Bay Speaker Panel Installation

    - by JordanD
    I purchased a bay speaker panel that has a molex connector and a sound connector. Do I need to run the sound connector through my tower and somehow out the back into the IO panel? Or is there supposed to be a place on my motherboard for it to connect to? This is a replacement for normal desktop speakers for me to save desk space. Edit: Is there an adapter for the sound cable to the mother board? If so; what is it called? Thanks

  • create symlink to another machine

    - by microchasm
    Hi, I have 2 machines. Both running CentOS. Box1 is webserver with apache, php. Box2 is mysql, and file storage. The files will only be accessible from Box1 within the webapp. I'd like to somehow create a symlink or somesuch on box1 to a folder on box2 where uploaded files can be stored and retrieved. Security in mind, what would be the best way to go about linking these 2 boxes up in a transparent (to apache) way? NB: the boxes are connected directly to each other via a crossover cable; no lan access to box2. Much thanks!
