• WOL doesn't work if set to anything other than `a` but this setting makes it boot all the time

  - by Elton Carvalho

  I manage a small "cluster" of 4 Xeon machines with Intel boards in my lab. They are all plugged to a 5-port 3-Com switch with static IP addresses like 10.0.0.x. They are all running OpenSuse 11.4 and their /home/ is served by one of the machines (node00) via NFS. They are plugged to an UPS that can keep them on for ca. 15 minutes, but there are lots of electric shortages due to "unscheduled maintenace" that are longer than this. So they end up being powered down without notice. If I set the BIOS to turn them on after power shortages, the issue is that they all boot at the same time and, if node00 decides to run fsck in the /home/ partition, it does not finish booting before the others try to NFS mount their /home/. I am trying to make wake on lan work, so I can choose to boot the NFS clients only after the server has successfully booted. The problem is that when I run ethtool I get an output like this: Supports Wake-on: pumbag Wake-on: g Theoretically, it is set to wake on MagicPacket(tm), according to the manual. But sending the WOL packet using wol -i 10.0.0.255 $MACADDR does not wake up the box after I shut it down with halt. The ethernet link led blinks after I send the packet, so it appears to be getting to the machine. However, if I set it up with ethtool -s eth1 wol bag, the machine always wakes up right after halting, even if I don't send the Magic packet. This means that the device can wake up with LAN activity, but seems to be ignoring the magic packet. Setting wol ag does not wake the box with the MagicPacket. Does setting wol a mean that it should boot with any broadcast message? How can I diagnose the issue of the machine not waking up with the MagicPacket even though I am sending it and it's set up to wake up with it? Thanks in advance!

• Backup files from Linux client to Windows Server

  - by Andrew

  I'm trying to backup my files from my Linux box to my Windows Server 2008 as a push, and when I delete them from my Linux box, they remain on my Windows Server. I've found lots of sources that are similar, but most results were from Windows to Linux. I managed to find slightly more similar cases like Using rsync and cygwin to Sync Files from a Linux Server to a Windows Notebook PC, and rsync from Windows PC to remote Linux server, with the most similar being a backup from Linux to Windows Server, but through a pull from the Windows Server. Initially, I used Unison because I thought having the 2-way capability would come in handy, and I would just have to set some configurations to make it 1-way. Unfortunately, I couldn't find the right configuration, and only managed to synchronize using the command unison "profile" -ui text -auto -silent. When I deleted the files on my Linux box, the files in the Server got deleted too, which of course, isn't what I want. When I tried to find any options for Unison, I only discovered the -force option, which didn't help, since what I wanted was an incremental update to the Server. I found out I could achieve this from using rsync and the -a option (archive), which would keep adding files even if I deleted them from my Linux box. I installed Cygwin on my Windows Server, configured an SSH daemon, but I can't seem to get it working. I've also already configured Windows Firewall to open port 22 (both inbound and outbound). I used the following command from my Linux box: rsync -avrzn /folder/to/be/backed/up/ [email protected]:/cygdrive/c/place/to/store/backed/up/files (a - archive, v - verbose, r - recurse into subdirectories, z - compress, n - dryrun) but it just won't work. Can anyone help me out? I don't mind using either Unison or rsync, as long as it achieves what I want.

• Can I connect a Playstation 3's HDMI output to my monitor's DVI-D input? [migrated]

  - by HankJDoomstorm

  I'm attempting to connect my Playstation 3 to my computer monitor. The monitor has a DVI-D (dual link) input, so before distinguishing between the different DVI varieties, I bought a DVI-I (dual link) to HDMI converter that won't fit into the port on the monitor (not only that, there isn't enough physical space in the back of the monitor to fit that much stuff before it hits the bottom of it). So I grabbed a DVI-D (single link) cable and got a female-to-female DVI-I coupler, and plugged the DVI-D cable into the monitor and the whole mess of converters. The end result was HDMI to DVI-D single link, but my monitor isn't receiving a signal on its digital channel. (For clarity's sake: DVI-D DL input on Monitor, DVI-D SL cable, DVI-I DL female-to-female coupler, DVI-I DL to HDMI converter, HDMI output on PS3) I don't know much about this stuff (obviously), but my educated guess is that the bandwidth of the PS3 is too high for the DVI-D Single Link cable, so nothing's getting through. Will replacing the single link cable with dual link resolve this? If not, is it possible at all? Oh, I should mention I'm aware I won't get audio through the monitor. I have an RCA to 3.5mm converter for that.

• Setting up SSL on JBoss 5

  - by socal_javaguy

  How can I enable SSL on JBoss 5 on a Linux (Red Hat - Fedora 8) box? What I've done so far is: (1) Create a test keystore. (2) Placed the newly generated server.keystore in $JBOSS_HOME/server/default/conf (3) Make the following change in the server.xml in $JBOSS_HOME/server/default/deploy/jbossweb.sar to include this: <!-- SSL/TLS Connector configuration using the admin devl guide keystore --> <Connector protocol="HTTP/1.1" SSLEnabled="true" port="8443" address="${jboss.bind.address}" scheme="https" secure="true" clientAuth="false" keystoreFile="${jboss.server.home.dir}/conf/server.keystore" keystorePass="mypassword" sslProtocol = "TLS" /> (4) The problem is that when JBoss starts it logs this exception (during start-up) (but I am still able to view everything under http://localhost:8080/): 03:59:54,780 ERROR [Http11Protocol] Error initializing endpoint java.io.IOException: Cannot recover key at org.apache.tomcat.util.net.jsse.JSSESocketFactory.init(JSSESocketFactory.java:456) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.createSocket(JSSESocketFactory.java:139) at org.apache.tomcat.util.net.JIoEndpoint.init(JIoEndpoint.java:498) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:175) at org.apache.catalina.connector.Connector.initialize(Connector.java:1029) at org.apache.catalina.core.StandardService.initialize(StandardService.java:683) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:821) at org.jboss.web.tomcat.service.deployers.TomcatService.startService(TomcatService.java:313) I do know that's there's more to be done to enable full SSL client authentication....

• Connect trough remote computer connection

  First, sorry for my english and my poor knowlodge of this subject. I have a dedicated server placed in Germany (windows 2008 R2) and I live in spain. I would like to access internet from my home computer (Windows 7 Pro x64), trough my server in Germany, so I can use a German IP, what I need some times. I have complete acces in to both computers, but I just don't know where to start.

• Network connection keeps dropping - bad hardware?

  - by Bill Sambrone

  Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

• Wake on Demand for Apache server in OS X 10.8

  - by Gary

  Mac OS X Mountain Lion does not have a Web Sharing box in the Sharing system prefs menu. It is thoroughly discussed on the web that the Apache server is available, and that it can be turned on manually in the command line, or by using a convenient Prefs Pane. That works while the computer is awake. But, when my computer goes to sleep, the server stops working, even though Wake for Network Access is checked in the Energy Saver Pref Pane. From the discussion on Bonjour, I see that this problem probably results from the fact that Apache isn't registered with Bonjour. Does that sound likely? If not, please make some suggestions. The connection is via hard-wired ethernet. If registration with Bonjour is the problem, I'd like to know how to register it. You gave a nice description of dns-sd, and the command description says dns-sd -R Name Type Domain Port [TXT...] (Register a service)", but I don't know what to use for "Name" or "Type", or the format of the domain. I tried some dns-sd -B searches and found nothing I could use as a model, and it doesn't show up in Bonjour Browser. Any suggestions would be appreciated.

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• Tracking IP through a socks5 proxy + RDP ?

  - by piro

  Hi all. We were having some issues at work until we found that we are being attacked almost every day. The attacker seems pretty smart - at first he was always using proxy to hide his IP. With scanning I found that they were socks 5 proxy. The last week we had 11 attacks and every time i found the ip i scanned it with nmap. I found that ALL of the 11 different ip addresses were RDP (port 3389 open, and accept rdp connections, checked by myself on ALL of them). So here follow the questions: 1. Can we trace his real IP back through a socks5 proxy ? 2. Can we trace him if he is using some RDP server to hide his ip ? Please do not answer like "Call the owner of the proxy server/RDP..." etc. we already tried it and it didn't work, that's why I am writing here. Thank you very much.

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  EDIT: I can only mark one answer as the correct one but the actual solution was a combination of two comments (updating the BIOS to A15 AND installing the Sigmatel audio drivers). I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime. I can't really afford the downtime to experiment with random drivers all day in case they turn out to be incompatible (Dell still hasn't added Windows 7 to their support site as far as I can tell). Does anyone have any other ideas? Has anyone had this issue and solved it? If so, how? Thanks in advance for your help.

• Best way to troubleshoot intermittent network outages?

  - by Ben Scheirman

  We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

• Firefox will not remember local site cookie

  - by Campo

  This is a weird one. We have a production server (Server 2008) and two staging servers (Server 2008 and Server 2003) I have sites on all of these. They all use cookies. On the Production server when browsing to our site www.supernovainteractive.com there is a cookie that detects when you visted the site and it will not refresh the logo animation (top left hand side) on clicking to another page. This works for all browsers on the production server. I’m not sure what’s going on but for some reason cookies are not working on one site in the 2008 staging server only. This is when browsing using Firefox (3.6.3) they work fine on all other browsers (IE, Chrome, Safari, Opera) In addition, the 2003 staging server works fine. You can test on the Supernova Interactive site by noticing the logo in the top left corner. It uses a cookie to detect if you’ve already seen the animation. Once you’ve seen it once, it doesn’t animate again until tomorrow. Currently, it’s animating every time. I have opened an outside facing port so others can see the issue. Http://exchange.supernova.com:10009 Any ideas on this one? Firewalls are off on the server. Notice you do not get a cookie from Exchange.supernova.com.

• Windows 8 Internet Explorer 11 proxy automation script

  - by Stefan Bollmann

  Similar to this post, I'd like to change my proxy settings using a script. However, it fails. When I am behind the proxy, IE does not connect to the internet. Here I try the first solution from craig: function FindProxyForURL(url, host) { if (isInNet(myIpAddress(), "myactualip", "myactualsubnetip")) return "PROXY proxyasshowninpicture:portihavetouseforthisproxy_see_picture"; else return "DIRECT"; } This script is saved as proxy.pac in c:\windows and my configuration is* in LAN settings: No automatically detected settings, yes, use automatic config script: file://c:/windows/proxy.pac No proxy server. So, what am I doing wrong? ---------------- update -------------- However, when I set up a proxy in my LAN configurations: IE -> Internet Options -> Connections -> LAN Settings check: Use a proxy Server for your LAN Address: <a pingable proxy> Port: <portnr> everything is fine for this environment. Now I try a simpler script like function FindProxyForURL(url, host) { return "PROXY <pingable proxy>:<portnr>; DIRECT"; } With a configuration described above** I am not able to get through the proxy.

• RPC Server Unavailable on Hyper-V cluster when moving resources after the host adapter has failed

  - by Doug Luxem

  On a Windows 2008 R2 SP1 cluster running Hyper-V, a lost network connectivity on the primary host interface. The interface was rapidly flapping up and down, and this was later determined to be caused by a faulty switch port. As this was a clustered server, the host interface was not fault tolerant (seeing as how the whole server was fault tolerant), so connectivity to the host was going up and down. The Hyper-V guests were completely unaffected by the network outage as they used a dedicated trunk on the server separate from the host interface. Additionally, dedicated interfaces for the cluster and live migration networks were fine. In order to diagnose the server, I tried to move all resources (Hyper-V Guests) to other nodes through Failover Cluster Manager. These moves failed with an error RPC Server Unavailable. The only way to move resources was by shutting down the guests, stopping the cluster service on the Node A, allowing other nodes to take ownership of the resources, and restarting the guests. A few other notes: All nodes have Client for MS Networks and File & Printer Sharing enabled on the Cluster and LM networks. Node A was accessible over cluster and LM networks from other nodes (these are private, cluster-only networks); pingable, CIFs, etc. Accessing \\NODEA is done over the Host adapters, as you would expect in this case and is the reason for the RPC Server Unavailable error with that adapter being down. My questions here are - Is there a way to still use Live Migration in a failure scenario such as this to prevent shutting down the Hyper-V guests? How can the network be reconfigured in the future so that the cluster service attempts to use the cluster and/or live migration networks to issue the RPC requests?

• Switched from DVI to HDMI, possible audio artifacts?

  - by I take Drukqs

  I'm using an ASUS VH236H monitor and an EVGA GeForce 570 GTX both of which are brand new. My monitor has an audio out port for speakers/headphones so I plugged in my headphones and made a random selection from my library when I noticed two things: There are static-like artifacts during "louder" parts of songs. There's what seems to be a volume cap in place. When I crank the volume past 100% in VLC the decibel level does not truly increase but the amount of static does. The cable is not new; I yanked it off of my PS3 when my DVI cable broke. It has been used a good amount on my HDTV and PS3 so I doubt it's a matter of burn-in. I like the way the setup works with an HDMI cable as opposed to DVI because my headphones barely reach my rig whereas I have plenty of slack when they're plugged into my monitor. Thanks in advance for any support. Note: I'm using a high quality HDMI cable from monoprice, AKG K702 headphones, and VLC media player.

• Can SSH into remote server but can't SCP?

  I can SSH into remote server just fine using private key authentication with prompt for passphrase. However I'm getting permission denied when I try to SCP a file using the same passphrase. Here's my output: $ scp -v [file] [user]@[remoteserver.com]:/home/[my dir] Executing: program /usr/bin/ssh host [remoteserver.com], user [user], command scp -v -t /home/[my dir] OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /home/[my dir].ssh/config debug1: Applying options for [remoteserver.com] debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to [remoteserver.com] [[remoteserver.com]] port 22. debug1: Connection established. debug1: identity file /home/[user]/.ssh/aws_corp type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3p1 Debian-3ubuntu7 debug1: match: OpenSSH_5.3p1 Debian-3ubuntu7 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.3p1 Debian-3ubuntu7 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '[remoteserver.com]' is known and matches the RSA host key. debug1: Found key in /home/[my dir]/.ssh/known_hosts:12 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/[my dir]/.ssh/aws_corp debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/home/[my dir]/.ssh/aws_corp': debug1: read PEM private key done: type RSA Connection closed by [remote server] lost connection I've searched for answers but can't find quite the same problem or am just being thick.

• Enable SSL with Jetty 8

• What are problems and pitfalls with a public facing Active Directory

  - by Ralph Shillington

  The situation that i'm faced with is this: We plan on using a number of server applications hosted on Amazon EC2 machines, mainly Microsoft Team Foundation Server. These services rely heavily on Active Directory. Since our servers are in the Amazon cloud it should go without saying (but I will) that all our users are remote. It seems that we can't setup VPN on our EC2 instance -- so the users will have to join the domain, directly over the internet then they'll be able to authenticate and once authenticated, use that token for accessing resources such as TFS. on the DC instance, I can shut down all ports, except those needed for joining/authenicating to the domain. I can also filter the IP on that machine to just those address that we are expecting our users to be at (it's a small group) On the web based application servers, I imagine all we need to open is port 80 (or 8080 in the case of TFS) One of the problems that I'm faced with is what domain name to use for this Active directory. Should I go with "ourDomainName.com" or "OurDomainName.local" If I choose the latter, does that not mean that I'll have to get all our users to change their DNS address to point to our server, so it can resolve the domain name (I guess I could also distribute a host file) Perhaps there is another alternative that I'm completely missing.

• Openvpn - stuck on Connecting

  - by user224277

  I've got a problem with openvpn server... every time when I trying to connect to the VPN , I am getting a window with login and password box, so I typed my login and password (login = Common Name (user1) and password is from a challenge password from the client certificate.

• Why does my microwave kill the Wi-Fi?

  - by Ohlin

  Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We've been annoyed by the instability of the Wi-Fi for some time and it wasn't until recently we realized it was correlated to microwave usage. After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more...but still! The router is a Zyxel P-661HNU ("802.11n Wireless ADSL2+ 4-port Security Gateway" with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an "internet connection" light on the router and it doesn't go out when the interruption occurs so I think this is only an internal Wi-Fi issue. Now to my questions: What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system? How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum? Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried? Since we were able to find router settings that cooperate well with our microwave's demand for attention, this question is mainly out of curiosity. But as most people out there...I just can't help the fact that I need to know how it's possible :-)

• How to pin "Visual Studio 2010 Documentation" shortcut to Windows 7 taskbar?

  - by Chris W. Rea

  I just installed Microsoft Visual Studio 2010 at home, on my Windows 7 PC. One of the items installed with VS2010 is "Microsoft Visual Studio 2010 Documentation". I like to have the documentation installed locally and at my fingertips, and so before had always added a shortcut for the help viewer to my Quick Launch toolbar. However, I'm not able to pin the new documentation to the Windows 7 taskbar. It's frustrating. Note carefully: When I launch "Microsoft Visual Studio 2010 Documentation" from the Start menu, it seems to perform two functions: First, it launches the "Help Library Agent", which is a local HTTP server from which the help content is served... similar to the local ASP.NET web development server. Second, it launches the default web browser against the localhost URL corresponding to the port on which the "Help Library Agent" is running, for example: http://127.0.0.1:47873/help/1-1444/ms.help?method=f1&query=msdnstart&product=VS&productVersion=100&locale=en-US ... in other words, the program doesn't leave behind an active foreground process that displays in the taskbar. So, I can't choose "Pin this program to taskbar" as one might do so with a typical program. How can I get a shortcut to "Microsoft Visual Studio 2010 Documentation" in the Windows 7 taskbar? Has anybody got a workaround for this?

• A router that supports connecting with 2 different wifi networks

  - by Allan Deamon

  I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

• DVI splitter not working as expected/confusion between DVI-D and -I

  - by Freakishly

  Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P
