• how to google a symbol keyword like "$?"

  - by ZhengZhiren

  i saw a trick in a book: in a linux shell, we can use &? to get the return value of a command. For example,we run a command,if it exit normally, the return value is 0. And then we type $?,we will get 0 in the screen. i want to google this kind of usage, so i have to type these two symbol $? in the search blank.But the search engine just return nothing to me... i have looked at the google help page, but still can't find a solution. so my question is: how can i search with this kind of keyword. or if you can give me some advise of the usage of $? or sort of thing, that will be also appreciated.

• Desktop file for my pythin script

  - by Jason94

  Hi! I would like to make a .desktop file for my Python script, but so far the only thing i have is a clickable icon on my desktop! It does nothing when i click it, so im guessing there is something wrong with the execution :) The desktop file: [Desktop Entry] Version=1.0 Type=Python Exec=/home/user/MyDocs/Python/EasySteer/Main.py Name=EasySteer Icon=steering_wheel X-Icon-Path=/usr/share/icons and I also tried: [Desktop Entry] Version=1.0 Type=Application Exec=/usr/bin/xterm "python /home/user/MyDocs/Python/EasySteer/Main.py" Name=EasySteer Icon=steering_wheel X-Icon-Path=/usr/share/icons But nothing works :D if it matters this is for my Nokia N900 mobile phone that runs Maemo linux, but i think the basics are the same.

• Drupal7 doesn't detect MySQL on CentOS, but Wordpress3 does?

  - by jyaworski

  Hey guys. I'm running CentOS 5.5 here with Apache2, PHP5, and MySQL 5. My wordpress install on the same system runs perfectly, but the drupal7 install script only detects SQLite. The mysql module is enabled in php.ini, so that isn't the problem. Do you think it could be something with Drupal 7, or my PHP install? I tested it on localhost (I'm essentially running ArchLinux with Apache) and it installs just fine. I don't see a difference between my local php.ini and my server php.ini. I get this when accessing install.php on the server. SQLite The type of database your Drupal data will be stored in. Your PHP configuration only supports a single database type, so it has been automatically selected. Edit: The mysql PDO module is installed already.

• How can I change shell in Ubuntu?

  - by Sanoj

  I have a Ubuntu Server VPS and I want to use /bin/bash/ as my shell. How can I change my shell? I have root access but I don't work as root. So dash is my default shell now. I have read How do I make Bash my default shell on Ubuntu? and chsh seams to be the preferred way to go. But when I type chsh /bin/bash I get this message: chsh: unknown user /bin/bash And if I just type /bin/bash the Bash shell seams to work fine. How to change it?

• WSUS Updates - Best Practice

  - by What'sTheStoryWishBone

  We have an isolated enviornment of a few hundred servers in which we use WSUS to push updates too. We have thousands of updates which to manage and push to devices testing along the way to ensure the update will not break anything. What are the best practices that you all follow in your enteprise networks to ensure an update does not go out to all the machines that will break something? We currently have ours broken into customized groups for each type of machine. There is one "Test Group" which has one PC of each type which we apply updates to for error checking. Is this a similar procedure others follow or is their an easier safer way to manage the thousands of WSUS updates?

• How to access vm inside a vm via VNC?

  - by can.

  For some reasons I installed virtual machines inside a virtual machine, like this: A( B( C )) where A is the physical machine, B is a vm and the network type is NAT. And C is also a virtual machine and the network type is bridged. The OSes are Ubuntu 12.04 and the hypervisors are kvm. I can access B via VNC and via ssh from A, but for C I can't use ssh because C has no IP address at the start. And I assume I can only access C via VNC. I tried something like(on A): iptables -t nat -A PREROUTING -d $ip-of-A -p tcp --dport 6500 -j DNAT --to-destination $ip-of-B:5900 (I referred to this) But it doesn't work. And I'm reading the man pages of iptables and hope someone could help :)

• OpenSSH (Windows) does not forward X11

  - by Shulhi Sapli

  I'm running Ubuntu 13.04 in VM and I wanted to do X11 forwarding to my host (Win 8), so far it works fine using PuTTY and XMing server for Windows. But I am curious why it doesn't work if I use OpenSSH binaries (it comes together with Git for windows). This is what I've done so far: ssh -X [email protected] (also tried with -Y) then gedit but received error of Cannot open display. echo $DISPLAY came out as empty. So, I try to export DISPLAY=localhost:0.0 but it still won't work. The DISPLAY environment that I set is exactly as when it runs with Putty. I also try changing the DISPLAY to 192.168.2.3:0.0 and other display number as well, but still it won't work. Of course I could just use Putty to make it work, but I was wondering why OpenSSH binaries does not work. I have enabled all settings required in both /etc/ssh/ssh_config and /etc/ssh/sshd_config. If I run with -v option, this is what I get F:\SkyDrive\Projects> ssh -X -v [email protected] OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to 192.168.2.3 [192.168.2.3] port 22. debug1: Connection established. debug1: identity file /c/Users/Shulhi/.ssh/identity type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_rsa type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.1p1 Debian-4 debug1: match: OpenSSH_6.1p1 Debian-4 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc 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 '192.168.2.3' is known and matches the RSA host key. debug1: Found key in /c/Users/Shulhi/.ssh/known_hosts:2 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,password debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/Shulhi/.ssh/identity debug1: Trying private key: /c/Users/Shulhi/.ssh/id_rsa debug1: Next authentication method: password [email protected]'s password: It seems that there is no request for X11 (I'm not sure if there is should be one too here).

• Windows XP, have to use ctrl+alt+delete to log on as local administrator

  - by wickedj

  Hey, I have a weird issue, a user was was logging into a laptop using the local admin account which was working fine. I had to create another account on the system, which was also an admin account, when this happened the 'administrator' account disappeared from the 'choose an account to login with' screen. A quick workaround is available, if the user presses ctrl+alt+delete it brings you to the screen where you can type in the username and password, so by manually typing 'administrator' it can log in. Normally this would be easily fixed, I figured the admin account had somehow been disabled from the local system, but i checked all settings and it is setup fine. The laptop is not part of a domain, so I used the management console to delete the new account and all that succeeded in doing was making the 'choose an account to log in with' screen display no accounts to choose. So far I see nothing else to fix it, the option to change the default logon screen to style where you type the username and password also seems to be missing. any ideas?

• How to modify existing keyboard layout (RU, kbdru.dll)?

  - by Anton

  There's a program I'm thinking of using called Punto Switcher that detects a language I'm typing in and switching entire word between Russian and English. The problem I have with this setup is that even though most of Russian letters "correspond" to English letters, Russian keys are scattered all over the keyboard and I don't feel like learning them all as I type in English mostly. Now, the program is very specific about me using RU, kbdru.dll file, not any other and if I use a custom keyboard under Russian, it doesn't recognize what I type so I think I should change the default RU keyboard. I created my custom keyboard using Microsoft's tool and I need to modify original one. I think it will take more than just replacing a file. Help?

• How to quickly start Programs like "regedit.exe" from the Windows 7 search bar using substring matching?

  - by Palmin

  The search bar in Windows 7 is very convenient to quickly start applications by pressing the Win-key and then entering the name of the application. For applications with a Program Menu entry like Firefox, it is sufficient to type Fire and Firefox will be displayed in the Programs section of the search results. For other applications like regedit.exe, I have to type the full command regedit before the correct choice regedit.exe appears. Is there any way to have regedit.exe appear already when I have just entered a substring? Please note: I have seen Add my applications to Vista’s Start Search, but I don't want to add anything to the Start Menu manually. This question is about if there is some configuration that can be tuned to make the results appear. I have also seen Search behavior of Windows 7 start menu, but my problem is not that the exe appears under Files, regedit.exe correctly appears under Programs, but it should appear already for a substring match.

• Raid1+0: create stripe over two /dev/mdx on partition or not?

  - by Chris

  Given that I haven't found a way to define how a Raid10 is created with mdadm, i went the Raid1+0 solution. How to display/define Mirror/Stripping pairs with mdadm mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdf1 mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdg1 /dev/sdh1 mdadm --create /dev/md10 --level=0 --raid-devices=2 /dev/md0 /dev/md1 My question is about the stripe. For the mirror I create a primary partition over the full HD and set partition type to FD. So, should I do the same for the Stripe? Create partition on /dev/md0 and /dev/md1 (primary over full 'HDD', set partition type correctly) and then do the stripe on the partition? Is there a correct way here or are there any advantages/disadvantages to a solution? Thank you

• Serial Port ttyUSB0

  - by Alex

  I picked up a USB serial null modem cable, so that I can connect up to a headless linux box. As a quick test, I plugged the device into the usb null modem, and the other end I connected to a windows pc. I opened up a terminal on the windows side, with 115200 8N1. On the linux side I opened minicom with the same params. MY problem is that I can type one way from the pc and see the text on the linux minicom side. If I type on the linux side it doesnt show on the pc side. If I reverse the cable it reverses the process. I bet this is a simple issue but I haven't dealt with serial comms in ages. Thanks

• Can't see a Windows XP computer on the network

  - by user56614

  I have two PC's connected to the same router. One is running Vista Home Premium and the other is running XP Pro. I'm trying to reach the shares of second PC from the first PC. I've enabled file sharing on the XP PC, I've disabled firewall and defender, and I can successfully ping it from the Vista PC. Both computers are set to the same workgroup "WORKGROUP". However, if I try to type "\\192.168.1.2" in Windows Explorer (192.168.1.2 being the IP address of the XP PC), I get a message: "Windows can't access \\192.168.1.2... Error code: 0x80004005 Unspecified error". And If I type "net view \\192.168.1.2" in command prompt, I get "System error 53 has occurred. The network path was not found." Am I missing something trivial?

• Using a Group Managed Service Account (gMSA) for a scheduled task

  - by Trevor Sullivan

  Back in Windows Server 2008 R2, when stand-alone Managed Service Accounts (sMSA) were new, they could not be used to execute scheduled tasks. In Windows Server 2012 however, there is a new type of account called the Group Managed Service Account (gMSA). This type of account is supposedly capable of launching scheduled tasks in the task scheduler on clients & member servers inside of a Windows Server 2012 forest/domain functional level. So far, I have: Established a Windows Server 2012 forest/domain Created a Group Managed Service Account (gMSA) Installed the gMSA on a Windows Server 2012 member server And currently I'm having trouble with: Setting a scheduled task to use the gMSA When I attempt to use a gMSA on a scheduled task, I get the error message that says "The object cannot be found" (paraphrased) message. My question is: How do I configure a Scheduled Task to execute using a Group Managed Service Account (gMSA)?

• Can a mapped network drive be reconnected from the command line?

  - by Stephen Jennings

  On a daily basis I find myself in the Windows command prompt needing to access a network drive that is mapped but disconnected. I have yet to find a command that will reconnect this drive without unmapping and remapping (which leads to a password guessing game, since I don't own these computers). I would also like to be able to script this so every night the drive is reconnected if it has become disconnected somehow. The fastest solution I currently have is to: Type "start." to open explorer, Alt-D to focus the address bar, type the drive letter I want and press enter, and wait for it to display the drive contents, then finally, close explorer and go back to the command prompt. I know it's a minor inconvenience, but I'm often doing this through a slow VNC or PCAnywhere connection where doing anything through GUI is awful, so I'm just wondering if there's a better solution.

• msn 2011 extremely laggy at time?

  - by chobo2

  Hi I am using msn 2011 and think they done a terrible job on it. It seems so buggy. At times when I type a message it is like a slide show. If I would type a sentence you could see it really struggle and the sentence would show up seconds after you typed it. This only happens sometimes. I heard this is something to do with some ad's that are making it slow. Does anyone have a fix for this? Also I noticed like 70% of the time when I check auto login(remember my password and username) it forgets that I checked the box the next time I start my computer up. So I end up typing in my username and password. Thanks

• Create my own custom ellipsis bullet point

  - by Airn5475

  I regularly use an ellipsis as a bullet point in a list of items in Word/Outlook 2010. Example: I like summer because... ... it's warm out. ... we go on vacation. ... my birthday is in July. Currently in Word/Outlook if you type certain characters like a hyphen and hit space, it will automatically start a bulleted list using the hyphen. I would really like the same functionality with the ellipsis. When I type the third period and hit space, start a bulleted list. Does anyone know of a way to do this? Registry hack? Hidden Word Setting?

• stop apache from asking for SSL password each restart

  - by acidzombie24

  Using instructions from this site but varying them just a little i created a CA using -newca, i copied cacert.pem to my comp and imported as trusted issuer in IE. I then did -newreq and -sign (note: i do /full/path/CA.sh -cmd and not sh CA.sh -cmd) and moved the cert and key to apache. I visited the site in IE and using .NET code and it appears trusted, great (unless i write www. in front which is expected). But every time i restart apache i need to type in my password for the site(s?). How can i make it so i DO NOT need to type in the password?

• < key triggers sticky alt on Windows 7

  - by Xoundboy

  When using a code editor like Notepad++ or Eclipse I'm experiencing a rather annoying problem: each time I type the < key the keyboard latches into some unexpected mode whereby the subsequent keypress behaves as if the alt key were being held down. The only way to return to normal mode is to hit the escape key twice immediately after I type a < character. The keyboard is a Microsoft Comfort Curve 2000 and the OS is Windows 7. Does anyone have any idea what I should do to stop this behaviour? Thanks

• Flash drive shows in My Computer but can't be accessed.

  - by Mr_Chimp

  I have a flash drive. When I plug it into my (Dell, Windows XP) computer it appears in My Computer as an empty drive - not a disk with no files on, a drive with no disk in! Double-clicking drive J: gives the message "Please insert a disk into drive J" (I get the same if I type in "J:" to the address bar, too...) Someone suggested going to properties and entering a name but it won't let me type in this box. I've looked in the disk manager and again it appears as an empty drive. I'm thinking that it might be fried...Can anyone give me any advice on how to either fix it or tell for sure that it's gone?

• Windows 7 -Can't get access to shared folder from one computer to another.

  - by Carbonara

  I have 2 windows 7 computers and i'm trying to share a folder (that I want password protection on) outside of the homegroup. Both computers are part of the same workgroup and I have the same user account/password combination on both computers plus I have password protected sharing turned on in the network and sharing centre along with file and printer sharing turned on. On computer 1 I have right clicked and selected that I want the folder shared. When I navigate via the network on computer 2 to computer 1 the shared folder shows up on computer 2 but double clicking on it to open it gives me an alert saying I don't have permission to access it, no option to type in the user name and password (according to the help files I shouldn't even need to type the password in if both computers have the same username/password anyway but would need it if I'm logged in as a different user). It's just a blanket denial of access.
