• IP Connflict on network

  - by PSU_Kardi

  I keep getting an IP conflict on my home network and can't figure out why. I'm running a Belkin-N wireless router that has an Ethernet connection to my 360 and a wireless connection running to my laptop. It's WPA2 encryption and I have a nice password on my router consisting of letters , numbers and special characters. But for some reason I keep getting IP conflicts at night time...By the time I look into the problem I don't see anyone else on the network. Is my router giving me false positives?

• Function keys require Fn modifer. How can I make them default?

  - by RickMeasham

  On my Dell Studio 15, the function keys, by default, do things like switch the radio on/off or change the brightness or sound. To use them as function keys I have to hold down the Fn modifier. I use function keys as function keys a lot more often than I want to change the volume or brightness. Am I missing an obvious setting somewhere in the control panel (Vista Uber Extreme Something)?

• Can I use TCP as DNS query protocol on Mac OS?

  - by Brian

  Hi, I'm using Mac OS, Snow Leopard 10.6.2, and I'm suffering from UDP packet loss during DNS query. So my web browser is too slow to surf internet nicely. But it worked very well when I tried a DNS query on TCP using dig command. However, I can't find some control switch to change to use TCP during DNS query. Is there a way to change it in Mac OS? Thank you.

• multilog compatibility wrapper for svlogd?

  - by pilcrow

  Has anyone written a compatibility wrapper for svlogd to function as a drop-in replacement for multilog? I'm a fan of UNIX process supervision in the style of daemontools and lately of runit. While runit offers a compatibility mode for many of the daemontools utilities, there is AFAIK no such offering for svlogd. I've got a few systems I'd like to switch over to runit, but I'd rather not modify the .../log/run scripts of every supervised process on those machines. Thanks.

• Mysql replication, Slow resyncing of slave after an error

  - by James Hackett

  I have a slave that got an error about a months or so ago and got way behind the master. I fixed the error and now playing catchup with the master but its going very slowly. Its going at 1.3x real time. I was using less that 10% of the db resources when these writes were first happening so the speed of the server shouldn't be an issue. Is there any settings I can switch to help the slave catch up with the master?

• Disable USB powered light from command line?

  - by Jeff Welling

  I have a nice little USB light which has no off switch, it is 'on' for the duration of being plugged in. My question is, is there a way of disabling the USB port so as to turn off the light while it is still plugged in? Preferably, this could be done from the command line, but if it's possible at all that would be really cool regardless. I use Mac and Linux, but am interested to learn if this is possible in any OS, or if physical hardware prevents usage like this.

• How to prevent dial up networking connection window from coming up on Windows 7?

  - by Tom

  I have PPP over Ethernet connection at home, so I have a dial up connection set up which comes up every time when I log in, so I can connect to the net by clicking on it. This works fine, but now I got a router which does the connection automatically, so there is no need for the dial up networking connecting window to come up. Nevertheless it comes up everytime when I log in regardless of the living net connection already established by the router. It does not cause any error I only have to cancel the dialog, but it's a nuisance and I can't find any setting to make it stop. Of course, I could remove the networking connection altogether, but I'd rather keep it, so I don't have to create it again if sometimes I need to connect to the net directly without the router. Is there a way to stop the connection dialog from coming up without removing the networking connection?

• GPO: Disable WiFi when computer is connected to LAN with wire

  - by r0ca

  Hi all! Is anyone of you know how to disable, thru a GPO, the Wireless connection as soon as the computer is connected to the LAN with a wire. By example, a user is at home with his laptop, connected to his home wifi connection. He leaves and comes to the office but the Wifi is still enabled. He plugs the ethernet cable in the computer and then, both wifi and wire connection are enable. I would like to apply a GPO that does this... Thanks a bunch!

• Recommending simple appliance for DansGuardian, iptables, snort inline

  - by SRobertJames

  I'm currently using a Linksys E2000 with dd-wrt. I'd like to add DansGuardian for Content Filtering and snort-inline for IPS; but those require a more powerful box (mainly, more storage). Can you recommend a good device to use? I'm open to both overwrite-the-firmware (like dd-wrt) and designed-to-be-customized boxes. Requirements: 1. 5+ Ethernet ports, pref. GigE 2. small form factor 3. No noise (office environment) 4. low power 5. Not sure about 802.11 wireless Budget < $400, pref. less.

• Passing parameters to a shell script running as a cronjob

  - by Takashi

  I am new to bash scripting (not programming in general). I am writing a bash script that will run a Python script I have written. I want to be able to do the following: Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo' switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).

• Methodologies for performance-testing a WAN link

  - by Chopper3

  We have a pair of new diversely-routed 1Gbps Ethernet links between locations about 200 miles apart. The 'client' is a new reasonably-powerful machine (HP DL380 G6, dual E56xx Xeons, 48GB DDR3, R1 pair of 300GB 10krpm SAS disks, W2K8R2-x64) and the 'server' is a decent enough machine too (HP BL460c G6, dual E55xx Xeons, 72GB, R1 pair of 146GB 10krpm SAS disks, dual-port Emulex 4Gbps FC HBA linked to dual Cisco MDS9509s then onto dedicated HP EVA 8400 with 128 x 450GB 15krpm FC disks, RHEL 5.3-x64). Using SFTP from the client we're only seeing about 40Kbps of throughput using large (2GB) files. We've performed server to 'other local server' tests and see around 500Mbps through the local switches (Cat 6509s), we're going to do the same on the client side but that's a day or so away. What other testing methods would you use to prove to the link providers that the problem is theirs?

• How do I resolve an "Invalid Transaction" error saving a zone config in Brocade Web Tools?

  - by Frank Szczerba

  When trying to save zoning changes in the Zone Administration tool in Brocade Web Tools, I get the status "Failed to commit changes to fabric" and the messages window shows: --- start of commit (Enable Config) at: Fri Jul 23 2010 19:43:40 GMT+00:00 Invalid Transaction --- end of commit at: Fri Jul 23 2010 19:43:47 GMT+00:00 I've tried refreshing the config and just re-saving what is already on the switch, but can't get this message to go away.

• Need advice to choose correct wi-fi drivers for Dell Vostro 3560

  - by overdriven

  I'm having problems with my Dell notebook's Wi-Fi, it can't see some of the available access points, despite they are close and I used to be connected to them yesterday. Other notebooks and my phone can see them. I believe it's a driver issue, since after installing system I haven't downloaded any network drivers. I went to Dell's website to search for them but I have no idea which should I choose. For my Dell Vostro 3560 and system Windows 8.1 64bit these are available: Intel Smart Connect Technology Application APP_iSCT_W8.1_A00_Setup-TJW84_ZPE.exe (23 MB) Vostro-3560_Network_Application_TJW84_WN_4.2.40.2418_A00.EXE (29 MB) Dell Wireless 1704 WLAN 802.11b/g/n (2.4GHz), Bluetooth v4.0+HS Driver DW1704_W8.1_A00_Setup-K1HGN_ZPE.exe (239 MB) Network_Driver_K1HGN_WN_6.30.223.143_A00.EXE (247 MB) Dell Wireless1703 802.11 b/g/n, BT4.0 + HS Driver Dell Wireless1901 802.11a/b/g/n (2.4GHz and 5GHz), Bluetooth v4.0+HS Driver DW1703_DW1901_Win8.1_A00_Setup-7FPWR_ZPE.exe (265 MB) Network_Driver_7FPWR_WN_10.0.0.263_A00.EXE (272 MB) Realtek RTL8105E/RTL8111E Ethernet Controller Driver LOM_Realtek_W8.1_A00_Setup-0XCVW_ZPE.exe (6 MB) Network_Driver_0XCVW_WN_8.018.0621.2013_A00.EXE (12 MB) Intel® Centrino® Wireless-N 2230 Bluetooth Driver BT_Intel_W8.14_A00_Setup-XR83W_ZPE.exe (31 MB) Network_Application_XR83W_WN_3.1.1307.0362_A00.EXE (37 MB)

• Where is debian storing its network settings?

  I have a debian machine that is supposed to have a static ip, but insists on getting its address from the DHCP server.

• Detect an IP address of a Wireless Access Point device

  - by dempap

  I have a Wireless Access Point device (http://www.szedup.com/show.aspx?id=1706), which I am planning to put into BeagleBoard-xM, in order to achieve wireless communication (LAN). However, I can't find it's IP address. I mean, I have to know it's IP address in order to connect with BeagleBoard-xM via a terminal emulator. For the moment, I have this device connected via Ethernet on my router. My router's setting page shows I have this device connected, but no further information. Is there any way to find the IP address of the Wireless Access Point? I hope of being understood. Any help would be really appreciated.

• Very slow printing from print server

  - by evolvd

  Print server is a VM on Xen The VM is Windows 2003 32bit. During the issue the VM is not being taxed in anyway, cpu, memory, hd read/write, and network speed is all good. The problem that I see is the transfer of the print file from the print server to the printer. The 80Mb file is transferred from the client to the print server in about 2 minutes but then it takes about 2 hours for that file to be sent to the printer. I can't figure out why this would just start to happen. The printer is rebooted every evening and is just used for one large print job in the morning. The server has been rebooted with no effect I changed the spool option to send the entire spool to the server before printing starts and it had no effect. This printer problem did happen to come about after some changes to the Xen environment. The Xen servers changed from using HBA NIC cards to software iscsi and a new switch was put in. I don't think this is related to the problem since all the speeds on the VMs are better now. The changed happened on Saturday and the first print to this printer happened on Monday morning. I'm just putting that out there but like I said I don't think it is related but I don't want to rule it out. At this point I don't have many other options besides the physical layer. I can switch out network cable that goes to the printer and I might be able to print the same job to another printer. I wont be able to test those things out till this afternoon though. Any other ideas or test I could do to try to find the reason for the slow speed? I forgot to say that this is only happening when printing to this one printer. ===Update=== I found out that there are a few printers that currently have this issue, not just the one. There are over 30 printers on the server though so I know it's not happening to all of them. I printed a large pdf doc from the server and it was able to print at the normal speed. If the machine sends the large print request it gets to the server fine but then slow to get from the server to the printer. If sent directly from the printer it gets to the printer at the normal speed. The question now is why is there a speed difference when it comes from the machine and why would it start now?

• VMWare Player: how to avoid always-on-top of other windows

  - by mklhmnn

  This question seems a little bit related, but not fully (I'm not using two monitors nor full-screen mode). I'm running VMWare Player 2.5.4 on Windows XP in normal window mode. Unfortunately, if I switch to other applications, VMWare remains the front-most window. I can avoid it by clicking the other application's title bar or if it pops up a dialog, but how can I avoid VMWare's "always-on-top"-mode completely?

• What are the popular file indexing engines on Linux?

  - by netvope

  It would be nice if you can share your experience on the pros and cons of each of them. Personally I only know Google Desktop and Beagle, and I haven't really used them. I mainly store my files on Windows (and use its integrated indexed search) but I'm trying to see if I can switch over to Linux. Also, can any one of the search indexer run without X? Does any of them provide an API for search queries?

• Routing table change to access Internet over mifi

  - by Randall Blake

  I have two networks at home. One uses a Verizon mifi wireless on 192.168.1.1. The other uses a dlink router on 192.168.0.1. I have one laptop with two nics, one wireless and one not. The wireless nic connects to the mifi. The Ethernet nic connects to the dlink router. It's ip is 192.168.0.2. I also have a laptop with only one nic connected to the dlink on 192.168.0.3. I want to connect laptop 2 to the Internet. Can I do that by adding an entry to the routing table so that destination 0.0.0.0 routes to 192.168.0.2? If I do that, will laptop 1 "know" that it should route traffic from 192.168.0.3 to 192.168.1.1? Thanks for any assistance.

• Home Media Streaming Server

  - by sharjeel

  I'm looking for a Home Media Server which can stream videos to various devices including iPhone, iPad, Windows Machines, Android etc. I wouldn't want to install any client on any device; a web interface will be preferred. Also, it should be able to read videos of as many formats as possible and should stream by transcoding the resolution and format according to device's specifications. I have a fairly powerful machine on which I'm free to install Windows 7 or Linux. The streaming will be done over a g/n WiFi router or Ethernet locally. What is the suggested solution in my case?

• Automatically disable devices to save power and mitigate DMA attack in Windows 7

  - by Martheen Cahya Paulo

  Some OEM include energy saving apps that can switch off certain devices such as webcam or optical drive. Is there any brand-agnostic app out there that can do it? If the list of disabled device is customizable, it would be useful too for mitigating DMA attack (disabling Firewire, PCMCIA, SDIO, Thunderbolt, etc). Even better if it can recognize lock/logoff event, to mimic OSX behavior in mitigating the DMA attack.
