• Windows 7 file explorer preview window and password protected word documents

  - by Carbonara

  When using the Windows 7 Explorer with the preview pane open you get a little preview of a file when you click on it. This includes Word, Excel spreadsheets, etc. My problem is if the Word document is password protected. Clicking on it in Explorer automatically asks for the password to display its preview. It does this if you single or double clicking on it. You then get an empty Word instance running (which allows it to display the preview) and another instance of Word with your actual file and you're asked for the password twice in total. This is annoying and untidy. Is there a way of stopping the preview pane from wanting to display password protected documents and thus not asking for the password to display a preview?

• Using cd Command in Windows Command Line, Can't Navigate to D:\

  - by nicorellius

  This may be a stupid question, and I think I have looked elsewhere to find the answer... Might be a path issue, but when I open the command line and type from the C:\>: cd D:\ I cannot get to the D drive. Even if I type: cd D:\<folder name> The command.exe will auto-complete the line with the tab key, so it knows where I'm at. It just doesn't print to screen the result or actually get me there. This problem exists for the network drives as well. Now, if I use the chdir (cd) command like this: chdir D: or cd d: I get the print out of the D:\ below the command but it still says I'm in the C:\. I feel like I'm missing something simple.

• How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

  - by Shwouchk

  I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?

• Determine display or VNC session based on PID

  - by Daniel Kessler

  I frequently VNC into a server where we run many concurrent computationally intensive matlab processes. Sometimes, one of my processes misbehave, which I can see from top, but I have a hard time figuring out which VNC session it's running on, or more specifically, which display it's running on. Suppose I see that PID 8536 looks like a resource hog, and I want to investigate. Because it's a matlab session, I know there is likely an IDE open somewhere, and I want to check to see if anything important is happening before I kill it. We've solved this somewhat awkwardly in the past by identifying which PTY 8536 was launched from, then looking at a process tree to figure out things launched in that context, scrolling up, and seeing the VNC initialization. Seems like there must be a better way to go PID - X Display (or VNC Session).

• how to set up domain name, bad request invalid hostname

  - by user45645

  assume i have a domain name which will be forwarded to my public ip (web server) automatically. in IIS 6, ip is public ip port is 6666, advanced - host value is www.hello.com firewall is open for 6666(web server port) and 53(DNS port), DMZ of router is my physical address in DNS, i have already had a zone called oldhello.com. And i expect a new domain name. So i have addded a new zone called hello.com and checked SOA server (P) is one.hello.local. then added a new host called one, full name is one.hello.com, ip address 192.168.7.3(my address in router) and then add a alias(CNAME) www, full name is www.hello.com, FQDN i choose the host i added before (one.hello.com) i expected that when i type the public ip in browser, can it be changed to domain name automatically. if not set host value www.hello.com, use public ip i can see the web however, after set up host value www.hello.com, browser show bad request invalid hostname

• Distribute Nagios to reduce false alarms

  - by GDR

  I'm currently running a single Nagios instance. From time to time, I'm getting false alarms about timeouts - for example, it says that HTTP is down on some server, but when I open it in my browser several seconds later, it loads fast, and in general there is no trace of an error. What can I do to reduce such false alarms? I'm guessing that it's because of transient network issues on my monitoring server. I guess that setting up another monitoring server on a different network would greatly help, but how do I plug it into Nagios? Is it at all possible with Nagios or do I have to switch to another monitoring system? I like my configs and, if possible, I'd like to stay with Nagios or something compatible (Icinga?)

  - by johnny

  Hi, I have a Dell 2850 and I want to install Windows 2008 Server. Problem is that my C drive only has 16GB of space. The requirements say I need at least 20. I have an open bay for a drive. If I put in another drive, how can I add that to the array and them make it only for the C drive? what do I do? Thank you. edit: I don't want to remove any drives. I just want to add a new one to the existing array. Can I do that and make sure that new drive is for the logical C drive?

• What are 'damaged files' on external hard drive (HFS format for OS X)?

  - by dtlussier

  I have an external HD formatted to default HFS (Mac OS Extended - Journaled) and very once and a while I get a folder called DamagedFiles in the root of the volume. The folder contains a collection of links to files on the drive. In general the files seem fine as I am for example able to open the images or text files without a problem. Is this serious? What can I do to fix this problem? Any advice would be great as I couldn't find anything on here or via Google that addressed this problem in particular. Many thanks.

• How do I bridge a connection from Wi-Fi to TAP on Mac OS X? (for the emulator QEMU)

  - by penx

  I'm trying to setup a bridge between my Wi-Fi connection and an emulator (QEMU). I need a virtual machine to be on the same LAN as the host, with its own IP address. QEMU requires using a TAP (virtual network device) so I have installed tuntaposx, have it running, and can open up QEMU using a TAP: qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -m 256 -net nic -net tap,ifname=tap1 -nographic -append "console=ttyAMA0" I have a script that configures the bridge once QEMU has opened up the TAP interface: sysctl -w net.link.ether.inet.proxyall=1 sysctl -w net.inet.ip.forwarding=1 sysctl -w net.inet.ip.fw.enable=1 ifconfig bridge0 create ifconfig bridge0 addm en1 ifconfig tap1 0.0.0.0 up ifconfig bridge0 addm tap1 ifconfig bridge0 up If I manually set an IP on the VM, I can ping from the VM to the host, but not from the host to the VM. Also, I can't access the rest of the network from the VM - including not being able to set an IP over DHCP. Any ideas?

• Link to user directory displayed with wrong name in start menu

  - by wierob

  In the start menu the link to my user directory is displayed with a wrong name e.g. foo When I click on the link in the start menu the explorer opens my correct user directory but the addressbar still names it foo. However, when I open a cmd from that directory the location is correctly shown as C:\Users\myUserName. Furthermore there is no C:\Users\foo directory. How can I fix this (i.e. ths link in the startmenu should be named myUserName)?

• Can I save a session in Chrome?

  - by EmmyS

  Is there a way to save sessions in Chrome? I'm a longtime Firefox user, and am used to being able to save a session containing multiple tabs so I can go back to it at any time. I'm trying to switch over to Chrome, but without this ability it's not going to happen. I know that I can set the prefs to open the last-opened tabs at startup, but that's not really the same as true session management. I'm perfectly happy to install an extension to do this if one exists. (Not sure if this question belongs here or in superuser...)

• I get a 403 when requesting a JS file from CloudFront

  - by Roland

  This is new to me so please excuse me if I have no idea what I'm talking about (: I'm trying to set up my own CDN with CloudFront and S3 through a subdomain by adding a CNAME to that subdomain to point to the CloudFront. It seems like I get a 403 when trying to load the file, this is the original s3 link : https://s3.amazonaws.com/chaoscod3r_aws_cdn/libs/polyfills/json3_polyfill.js ; which seems to be working after setting the permission to everyone to open / download. But when trying to use the subdomain to request the file : http://cdn.chaoscod3r.com/libs/polyfills/json3_polyfill.js ; it seems like I get that 403. Could anyone help me out with this one ?

• On Windows 7, how can I tell if a recording is multi-channel without third party tools?

  - by engineerchuan

  A customer has an audio that is confidential and can't send it to me. He also would not like to install other tools. He has a basic Windows 7 install. Is there any way to tell whether the recording is one channel or two channel? Normally, I would just get the audio and soxi it. Or, I would tell him to install Audacity or equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get number of channels but bit rate already factors in number of channels. Sorry I'm not giving you a lot to work with.

• How do I get rid of "Trusted Drive Manager"?

  - by Earlz

  I have a Dell laptop that's been experiencing some weirdness lately. Apparently Dell puts "Trusted Drive Manager" on their hardware.. Well, now I keep getting these errors: I tried uninstalling Dell Data Protection, but it says some other package is required for the installation, which I can't install because I'll get another generic error (Dell Data Protection Access Drivers). This error pops up when I first boot, when I open a save file dialog, when I try to do a disk cleanup. How the hell do I get rid of this!?

• Copy-paste stops working on Windows 7

  - by earlyadopter

  Copy-paste functionality stops working after about an hour after each reboot on a Windows 7 64-bit system. Running Google Chrome (with gmail and few other tabs open like Calendar, Reader), MS Outlook (which I don't think has anything to do with the problem — I saw it when outlook was off as well), iTunes (9.1.1.12 if it matters). Would appreciate hints where and what for to look in a registry, and ideas for possible fix. That is not an Internet Explorer problem (I don't even run it) — it happens in all applications. Neither Ctrl-C/Ctrl-V nor context menu right-click Copy-Paste (actually, nothing happens on Copy, so there is nothing in a clipboard to Paste) are working. Drag-and-Drop (where supported) continues working though.

• trouble loggin into a Mac share from a Windows PC on the network

  - by villares

  I have this mixed network and usually log into the Macs from the Windows XP home machines and vice versa. I have no real networking knowledge, things just seem to work, more or less, with the default settings. Now I've got a new Snow Leopard Mac with a shared folder (added the user names of the Windows users at the sharing preferences) and the trouble is some machines can open the share and others can't. I can't see the difference. It feels like some Windows machines have a "cache" and won't ask for the share password, just deny access. I can also see old shares proposed at the Windows "add network place wizard".

• WD Passport Won't Mount

  - by Scott7278

  My WD Passport won't mount. However, it turns on when plugged into my macbook and doesn't make any strange noises. It took a small fall (just a few inches and it was on my couch) and I'm very concerned about physical damage. When I open up disk utility it shows the root 500 GB WD My Passport drive which seems to be OK when I verify it and repair it. However, the "External Hard Drive", the directory underneath the "500 GB WD My Passport drive" is grayed out. When I verify the External Hard Drive it says it needs to be rapaired. When I try and repair it it gives me the following message and does not seem to progress: "Updating boot support partitions for the volume as required." Is there hope for me recovering my data? I stupidly have important data on it that I don't have anywhere else.
