  • Why does the Mac OS X firewall dialog recurringly pop-up and disappear by itself (without letting me

    - by Chris W. Rea
    From time to time, I'll be on my Macbook using a program that accesses the network – whether Firefox, or Sony's Reader Library – really, it seems like it could happen with any program that accesses the network – and for no reason that I can discern so far (that is, it happens intermittently) the OS X firewall dialog pops up to ask me the question: Except it doesn't actually let me click anything before it disappears! That is: the dialog pops up, ... then goes away by itself a second later, then pops up again, ... then goes away by itself a second later, etc. It happens a few times before stopping. It wouldn't be so maddening to be interrupted if I could just be allowed to click "Allow" and make the darn thing go away for good. In Security preferences I have the firewall turned "On", and I would like to keep it that way. Has anybody seen this problem, found the source, and figured out a solution or workaround? Thank you.

  • How can I view my video card's temperature via SSH?

    - by NT3RP
    I've finally managed to set up my two ATI Radeon 6950 video cards in my machine, but the cards can get quite hot. Based on the arrangement of my apartment, I want to be able to SSH into the machine an execute a command to find out the temperature. What I have tried so far is this... export DISPLAY=:0.0 sudo aticonfig --adapter=0 --od-gettemperature However, when I do that via SSH, I get the following error: ERROR - X needs to be running to perform ATI Overdrive(TM) commands If I turn on X forwarding when I remote into the machine, then it just seems to affect my local machine instead of the remote machine. Am I doing this correctly? Is there a better way to monitor my video card's temperature?

  • Windows 7 Sharing issue on RAID 5 Array(s)

    - by K.A.I.N
    Greetings all, I'm having a very odd error with a windows 7 ultimate x64 system. The network system setup is as follows: 2x XP Pro 32 Bit machines 1x Vista ultimate x64 machine 2x Windows 7 x64 Ultimate machines all chained into 1x 16 port netgear prosafe gigabit switch, the windows 7 & vista machines are duplexed. Also there is a router (netgear Rangemax) chained off the switch I am basically using one of the windows 7 machines to host storage & stream media to other machines. To this end i have put 2x 3tb hardware RAID 5 arrays in it and assorted other spare disks which i have shared the roots of. The unusual problems start when i am getting Access denied, Please contact administrator for permission blah blah blah when trying to access both of the RAID 5 arrays but not the other stand alones. I have checked the permission settings, i have added everyone to the read permission for the root, i have tried moving things into sub directories then sharing them. I have tried various setting combinations in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa and always the same. I have tried flushing caches all round, disabling and re-enabling shares & sharing after restart as well as several other things & the result is always the same... No problem on individual drives but access denied on both the RAID arrays from both XP & Vista & Windows 7 machines. One interesting quirk that may lead to an answer is that there is no "offline status" information regarding the folders when you select the RAID 5s from a windows 7 machine yet there is on the normal drives which say they are online. It is as if the raid is present but turned off or spun down but as far as i was aware windows will spin an array back up on network request and on the machine itself the drives seem to be online and can be accessed. Have to admit this has me stumped. Any suggestions anyone? Thanks in advance for any fellow geek assistance. K.A.I.N

  • HP Presario CQ 61-322ER (VV884EA) Wi-Fi hang up!

    - by qgrabber
    I have my new laptop and don't have Windows XP drivers for it. I found that it contains the Broadcom BCM4310 chip, but when I install any Broadcom driver my laptop hangup on installing bcm5*.sys driver. Only power-off button make any effect. After reboot the device list (Device Manager) contains Broadcom WLAN adapter, but it is marked as disabled, for some hardware errror! Also if I disable device before, and install driver - then - all is OK! But when I try to enable it, Windows hang up anyway (no speaker beep, no mouse input, no keyboard input - nothing) What is the solution?

  • 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

  • Can DVI look different?

    - by queueoverflow
    I have a desktop with an nVidia GT 9500 which has two DVI slots. I have a 24" TN-Panel TFT on that and it looks pretty good. Then I hooked it onto the DisplayPort of my ThinkPad with the Intel HD 3000 card with an DP-DVI adapter and I think that the fonts look even clearer. Both computers run Kubuntu 12.04, although the ThinkPad is freshly set up, while the desktop is migrated from the previous release. Is this a hardware thing or is it just some setting in the anti-aliasing or sub-pixel-hinting?

  • How do I improve picture quality while streaming live football (soccer) from my Dell D600 to an HDTV?

    - by Bob
    I have fibre broadband with speeds up to 38mbs, my Dell D600 has its max 2gb ram and has an ATI Mobility RADEON 9000 4xAGP 32mb card in it...Its TV support it says is NTSC or PAL in S-video and composite modes with a 7-pin mini-DIN connector (optional S-video to composite video adapter cable) and a vga port which i am using at the moment... The laptop runs Windows XP, an 80g HD with only windows + necessary updates and anti virus software on it..... There is HDMI on the TV, but not the laptop Fairly slow moving and close up pictures arent too bad, but when the movment is fast(a shot on goal) or in the distance, I cant see the ball and the images go out of focus.

  • VM: Windows 7 host, Linux guest, VT-d?

    - by chx
    I am sick of the driver issues of Linux. So I am planning to switch to Windows 7 as a host and virtualize my Linux into it. My laptop has integrated Intel graphics and supports VT-d. For speed reasons I would like to assign that card to Linux. Now, Parallels could do it but this page says Note: If you have only one PCIe video adapter, its name will be grayed out in the PCI Devices list and you will not be able to allocate it to your virtual machines. I would be perfectly fine with a headless Windows 7 (I can remotely admin from other computers or just the Linux guest) -- is there any VM software that doesn't have this restriction?

  • No outbound internet connection after restarting CentOS 6.3

    - by wnstnsmth
    After restarting a headless CentOS 6.3 machine, it lost outbound internet connectivity, i.e. I can still connect to the server via SSH (ssh root@**.126.18.56), but stuff such as ping google.com gives google.com: unknown host, and yum list some_package gives a lot of network errors. This is what ifconfig gives: eth0 Link encap:Ethernet HWaddr 00:25:90:78:2D:5D inet addr:**.126.18.56 Bcast:**.126.18.255 Mask:255.255.255.0 inet6 addr: fe80::225:90ff:fe78:2d5d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75594 errors:0 dropped:0 overruns:0 frame:0 TX packets:787 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7074741 (6.7 MiB) TX bytes:144391 (141.0 KiB) Interrupt:20 Memory:f7a00000-f7a20000 eth1 Link encap:Ethernet HWaddr 00:25:90:78:2D:5C UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:16 Memory:f7900000-f7920000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:504 (504.0 b) TX bytes:504 (504.0 b) I have absolutely no clue how to debug this, and I find it very strange since I can still connect via ssh. EDIT: Weirdly, /etc/resolv.conf does not contain any entries, or none that I can make sense of: # Generated by NetworkManager search sui-inter.net # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com So is it possible that rebooting the server erased that file? It worked before at least! And how do I solve this? By the way, pinging an IP address works.

  • What's the best multiple monitor setup I can buy for $500 and a macbook?

    - by kevinburke
    I've got a 13' white MacBook from 2008 and I'd like to run one or two external monitors, my budget is $500. I've tried to do research and this is what I was going to get - will these work OK? Two Diamond BVU195 HD USB Display Adapters (DVI and VGA with included DVI to VGA adapter) to plug into the USB port Two Dell ST2310 monitors One external USB hub so I don't use up both of my USB ports Will this work? I've read some people say it does and some people say it doesn't, but I don't know enough to say either way. Also do you have recommendations for a better monitor than the dell sd2310? what's the best setup I can buy for $500? Thanks very much for your help, Kevin

  • Website always having DNS problems

    - by Root
    I moved my website from shared hosting to VPS. When it was in shared hosting all I did is updated my name servers whereas now I got my own VPS server and I used one of my domain sjdpublishing.com as the primary domain for my VPS. I created nameservers as ns1.sjdpublishing.com and ns2.sjdpublishing.com and then my actual website is creativeproperty.com.au which are pointing to ns1.sjdpublishing.com and ns2.sjdpublishing.com I am having repeated problems with my domain creativeproperty.com.au a few weeks back I had a problem which was resolved by flushing DNS and later I got similar problem which was not resolved by flushing DNS, I posted a question here and someone answered me to go to Network Settings in my MAC OSX and remove the IP as in my MAC terminal nslookup creativeproperty.com.au points to my router IP and I fixed this problem Now many of my clients were complaining that they are having same troubles accessing my website. I don't know whether its to flush DNS or change network settings or other issues. Can anyone please check my domain creativeproperty.com.au and sjdpublishing.com are having correct records or not and also can anyone tell me the best solution for this issue?

  • Dual Monitors don't turn off/sleep when they should

    - by Mario
    Details: Dual 25" monitors connected to HP Envy via HDMI and display port via DVI adapter. Power scheme is set up in high performance (Dim Display: Never - Turn Off Display: 15 mins - Computer Sleep: Never) Screensaver is set up to kick in after 10 mins of idle (which happens) 5 minutes later, the screensaver stops. The "Monitor Going to Sleep" notice appears on screen and monitors go to sleep briefly. All is well thus far. Suddenly, the Windows 7 alert sound when a device is unplugged is heard. Monitors then turn back on. Screens are black. Only the mouse cursor is displayed. Backlighting is back on. This only started happening after I obtained and connected the second 25" monitor a few days ago. However, I had a 24" in its place before, and this wasn't happening. Why is this happening and how do I correct this behavior? Thanks in advance.

  • Wifi antenna extension with F-connector/RG-6(RG-59) cable?

    - by rjz2000
    In an older house, the wire mesh in walls surrounding the furnace behave like a Faraday cage and block wifi signals. It is also difficult to lay new cable, however there is television cable to multiple locations due to there once having been a roof-installed, television antenna. It would be relatively trivial to install the wifi router at the center distribution point, then have the antenna broadcasting/receiving the signal plugged in at each of the old television outlets. I assume that it would not be too difficult to find an adapter for SMA <- F-type connectors. The cable is actually RG-59 rather than RG-6, but I assume that it still has relatively good RF isolation along its length, which is no more than a couple hundred feet in any direction. Does anyone know a problem with the idea? Will a router get confused if there is /too little/ interference between the two antenna? Is that length of cable (~100ft) too long for the signal a router broadcasts? I have seen that it is also possible to use old ~$30/each FiOS cable modems available on eBay to extend a network over television cable. However, that seems like a less elegant solution, and might interfere with upnp and dlna services I'd like to have work on a single network. Thanks if anyone has answers or suggestions before I try this project!

  • Samba access works with IP address only

    - by Sebastian Rittau
    I added a Debian etch host (hostname: webserver, IP address: 192.168.101.2) running Samba to a Windows network with a Windows 2003 PDC (IP address 192.168.101.3). The Samba server exports a public guest share, called "Intranet". The server shows up fine in the network, but trying to click on it produces an error dialog, stating I don't have the necessary permissions. So does entering \webserver manually and using \webserver\internet states that the path does not exist. Interestingly, accessing the share by IP address (\192.168.101.2 or \192.168.101.2\intranet) works fine. DNS is configured correctly, and "smbclient //webserver/intranet" on another Linux client works fine. One complicating issue is that the webserver is only a VMware virtual machine running on PDC server. Here is our smb.conf: [global] workgroup = Foobar server string = Webserver wins support = yes ; commenting out these wins server = 192.168.101.3 ; two lines has no effect dns proxy = no guest account = nobody [... snipped some unrelated bits, like logging ...] security = share [... snipped some password-related things ...] domain master = no [intranet] comment = Intranet path = /srv/webserver/contents browseable = yes guest ok = yes guest only = yes read only = yes create mask = 0775 directory mask = 0775

  • Share the DVB card on windows 7 [closed]

    - by Bashar Kernel
    I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

  • File corruption (bad checksums) in large files copied to VMware guest

    - by AllanA
    In setting up a development lab, I've got a desktop system running ESXi 4.1.0 (free license) on SATA RAID 0 (already purchased and configured when I started this job; I'm open to hardware input as it pertains to my problem.) Its guests so far include two Win2008 Server R2 64-bit VMs and on Ubuntu 10.04 64-bit VM. I'm installing onto the Windows servers. We've been copying off some fairly large files (over a gigabyte) for an installation, hoping to install more quickly from a (virtual) hard drive than from the network for from BD-ROM. The problem is that they keep coming up with different checksums from the originals. The file sizes are the same, but md5sum reports different numbers (and so does the installer, as it refuses to continue when the checksums don't match.) I've tried copying directly from the BD-ROM (attaching the OS drive to the host system's physical drive). I've tried copying the large files onto a co-worker's Windows machine from his Blu-Ray drive; when I do that, the checksums match. But when I copy from his machine to the VM guest over a network share, the checksums no longer match. Thinking this meant a corrupt destination drive, I deleted it in vSphere and added another freshly created drive. The problem persists. I'm not sure what to try next.

  • Searching SharePoint site with Windows Explorer

    - by alexsome
    Every week, I manually backup recent versions of the files on my group's SharePoint site. I open the library in Windows Explorer, search for all files modified in the past week, then copy and paste them to a network location. We need this process because our SharePoint site has a quota that we would easily meet if we had unlimited versions, so we keep a history of older versions on the network. Recently I got an upgrade to my work computer and I am unable to search the site using Windows Explorer. When I run the search for files modified in the last week no results are returned. If I run a search with no criteria on the file library, all the files are found but the "modified on" field is blank. So the search results only have the file and type fields. The new computer has Windows XP, just like the old one did. I hope this makes sense. Does anyone have any clue what the problem could be? I'd be happy to provide more info if necessary. It's bugging me to no end and I'm not even sure where to begin looking - it's either a trivial issue or a very obscure one. Thanks a lot.

  • Replicated filesystem and EC2 MySQL

    - by El Yobo
    I'm currently investigating migrating our infrastructure over to run on Amazon's EC2 and am trying to figure out the best way to set up a MySQL service. I'm leaning towards running our own MySQL instances, rather than going with Amazon's RDS, but am still considering the best approach for performance and cost on the instance itself. In order to have persistent data, the MySQL data needs to be on an EBS volume (with some form of striped RAID, e.g. RAID0 or RAID10) to improve persistence. However, EBS IO is limited by the network interface (gigabit, so a theoretical maximum of 128 MB/s), while the ephemeral volumes have no such problem. I did see a suggestion for running two MySQL servers on an instance, with a master running on the ephemeral disk (which we would also RAID) and a slave storing changes to an EBS volume, but this has some additional overhead and complexity (two servers). What I was imagining is using some form of replicated file system such that I could have a filesystem on top of a RAID0 of ephemeral volumes to maximise performance all changes from the above immediately replicated to another RAID1 volume backed by multiple EBS volumes to ensure no data loss The advantages of this would be best possible IO performance for the DB server; no network delay in IO decreased IO on EBS volumes (as all read IO will be done on the ephemeral volumes) so decreased cost good data security, as it's backed onto redundant EBS volumes However, I haven't seen an appropriate system to replicate all changes from one volume to the other; is there a filesystem, or any other approach, which will do this? The distributed file systems, e.g. GlusterFS, DRBD etc seem to focus on replicating disks between servers, can they be set up to do what I'm interested in here? I also haven't seen anything about other's taking this approach. Do I have a solution in need of a problem here (i.e. is performance good enough, so this whole idea is redundant)? Is there some flaw in the plan?

  • Setting up a virtual ftp directory that points to another computer

    - by AngryHacker
    I have II5 sitting on an old Windows 2000 Professional box. It has an FTP site there that allows me to access files. It works great, no problem at all. However, now I need to setup a virtual directory that points to a share on another computer on the network (running Windows XP Tablet Edition). The share requires a user name and password. The network is a simple workgroup (i don't have any domains or any of that). What is the correct procedure for that? I've tried setting a share via UNC and typing in the UserID/Password when asked. But when I finished, the virtual machine showed up as an error in the IIS Manager and couldn't access it. I mapped the share onto a drive and then tried to setup a virtual directory with this drive. Same result. Is there something simple I am missing? Would upgrading any part of the picture help at all?

  • Wi-Fi won't automatically connect (box in Windows configuration gets unchecked)

    - by greg88
    The checkbox that says "Use windows to configure my wireless network settings" keeps getting unchecked (Wirless Network Connection - Change advanced settings - Wireless networks tab.) How do I stop that from happening? (So the wi-fi will reconnect.) When I manually re-check the box, it automatically connects.) I have a D-Link AirPremier DWL-G550 PCI adapter. I installed the newest driver, 5.3.0.46, and that didn't solve the problem. I took the "Atheros Client Utility" (the program window says "D-Link AirPremier Client Utility" when you run it) out of the start menu, rebooted, and that didn't solve the problem. (That utility puts a signal bar similiar to the one MS Windows puts there, and it's gone now.) The D-Link client utility has an option to automatically connect to preferred networks, but it is greyed out. It is also greyed out if I install the driver and utility right off the D-Link installation CD, so the problem isn't that the utility and driver are incompatible versions. I want to use Windows to handle the connection anyway, as the D-Link utility is garbage. Windows XP SP3 w/all current updates.

  • Nginx and Wordpress side-by-side with static directory alias?

    - by user117161
    I'm a Nginx novice, but I have it set up with Wordpress Multisite (subdirectories) and php-fpm, and it's working great as is. This lets me set up Wordpress sites off the web root: domain.com/site1 - a Wordpress network single site, which renders as expected. domain.com/site2 - ditto etc. Concurrently, I can easily create static files in the web root that don't conflict or interact with Wordpress, and they are also rendered normally. domain.com/hello.html - rendered normally domain.com/hello.php - rendered normally, including php processing domain.com/static/hello.php - rendered normally (along as "static" isn't a WP single site name) What I'd like to do, and this is where I'm out of my depth with nginx.conf, is create a root directory domain.com/static and put static sites in there domain.com/static/site3 domain.com/static/site4 and have Nginx check the request that comes into the root request comes in for: domain.com/site3 and before handing off to Wordpress, check to see if it exists in the /static folder checks: domain.com/static/site3 - static content exists there and if so, serves that content while maintaining the root URI. serves: domain.com/site3 (with content from domain.com/static/site3) if not, it lets Wordpress check if /site3 is a Wordpress single network site as it does now, and the process continues normally. In nginx.conf, in the server section, I start with this try_files rule: location / { try_files $uri $uri/ /index.php?q=$uri&$args; } I then include a bunch of Wordpress specific rules as identified at http://codex.wordpress.org/Nginx under the subdirectory section. I can see that rewrite rules might take care of it easily, but in my experimentation I've only achieved a bunch of looping (/static/static/static, etc.) and managed to bypass Wordpress if the looping stopped. Sorry if this is a very long-winded way of asking a simple question, but I'm definitely learning some of this stuff for the first time. Thanks!

  • Why is my rsync so slow?

    - by iblue
    My Laptop and my workstation are both connected to a Gigabit Switch. Both are running Linux. But when I copy files with rsync, it performs badly. I get about 22 MB/s. Shouldn't I theoretically get about 125 MB/s? What is the limiting factor here? EDIT: I conducted some experiments. Write performance on the laptop The laptop has a xfs filesystem with full disk encryption. It uses aes-cbc-essiv:sha256 cipher mode with 256 bits key length.

  • Throughput and why do ISPs sell too much bandwidth?

    - by jonescb
    I hope the question made sense how I worded it. :) I've been wondering, maximum theoretical bandwidth is measured as RWIN/RTT (Window size / round trip time) Source 1 and Souce 2 So if a major city only 100 miles away gives me a ping of 50ms, and I have the default 64kb TCP window size then my maximum throughput will be 12.5Mb/s. Everything further away would give me a higher ping and therefore a lower throughput. Is there any reason to buy something like FiOS with a 50Mb/s or greater connection? Will you ever be able to reach that kind of speed? I know you can increase the TCP window size to increase throughput, but it has to be at both ends which is a deal breaker because you can't control the server. I'm assuming other network protocols like UDP aren't quite as affected by latency as TCP is, but how much of overall network traffic does non-TCP make up vs TCP. Am I just misguided about how throughput works? But if the above is correct, then why should a consumer like me buy way more bandwidth than can be realistically used. Maybe the only reason is for downloading multiple things at once, or one thing from multiple servers/peers?

    I've seen this question asked several times here on SF, but I'm looking for some updated information; specifically concerning Server 2012. I'm in the process of buying a home so I'm trying to get some plans together on how I want to structure my network. Internet speeds aren't the greatest and connections can be unreliable where the house is so I was thinking of having two DSL lines installed. My question is, how could I leverage those two connections to create the best network I can, in terms of speed and reliability. My parents will be moving in with me - they consume a lot of bandwidth as it is, but then add my internet traffic to it, and I'm headed for a lot of frustration. I thought I remember reading somewhere that Server 2012 has some new functionality to utilize multiple connections on multiple NICs in a way that wasn't possible in earlier versions of Server. Not sure if Windows will work but, I'm an application developer and spend the majority of my time in Windows environments. However, I've only recently returned to the Windows world, so I'd like my main server at home to run Win Server 2012 so that I can become more familiar with it.
