  • Creating a user called 'root'

    - by pnp
    I am creating Virtual Machines using the ubuntu-vm-builder. The syntax goes something like this: ubuntu-vm-builder kvm precise \ --domain newvm \ --dest newvm \ --arch i386 \ --hostname hostnameformyvm \ --mem 256 \ --user john \ --pass doe \ --ip 192.168.0.12 \ --mask 255.255.255.0 \ --net 192.168.0.0 \ --bcast 192.168.0.255 \ --gw 192.168.0.1 \ --dns 192.168.0.1 \ --mirror http://archive.localubuntumirror.net/ubuntu \ --components main,universe \ --addpkg acpid \ --addpkg vim \ --addpkg openssh-server \ --addpkg avahi-daemon \ --libvirt qemu:///system ; I need to enable the 'root' user account after creating each of my VMs (and supply a password for it). I was just wondering whether I can take this short-cut of supplying the username (--user) as root in this command itself. If I supply username as root to create my VMs, am I creating/enabling the root user, or just creating a user named as root? p.s.: any better ways to achieve my task are also welcome. But I don't want to manually meddle with each VM after its creation

  • Preseed Ubuntu installation with full disk encryption

    - by user249264
    I am trying to set up Ubuntu full disk encryption using preseeding. I was able to set things up correctly following the preseed file presented here. But I do not want to provide the default password in the preseed file. Is there a way to let ubiquity fall to the screen that asks for the encryption passphrase just like it does when the username is not provided in the preseed file? When I try to leave the passphrase option empty in the preseed file, I get an error in the installer saying "An error occured while creating the keyfile".

  • SSH Lost Terminal Colors

    - by memecs
    I have to computers with exactly the same configuration (same PS1 etc...). When I ssh from A to B the terminal correctly displays PS1 and file type colors (i.e. blue directories, green executables etc.) But when I ssh from B to A PS1 is set to default and colors disappear. Furthermore, I created public keys to ssh without password from A to B and vice-versa. It works correctly from A to B but it doesn't work from B to A, again I repeated the exact same procedure on both pc: On Host A ssh-keygen ssh-copy-id -i ~/.ssh/id_rsa.pub address.to.host.B On Host B ssh-keygen ssh-copy-id -i ~/.ssh/id_rsa.pub address.to.host.A What could be the problem?

  • Can't login to my XFCE environment from lxdm

    - by Noob
    I installed lxdm as my display manager because I heard its very lightweight. Now after installing it when I select my Desktop as Xfce session I am not able to login. Basically what happens is it waits for sometime and than reload the same login page. On the other hand if I select lxde as my Desktop I am able to login. So, what am I doing wrong here. The other problem I am facing with lxdm is it doesn't show my default user account. I have to select more and enter both my username and password to login into any session.

  • FxCop ... Where have you been all my life?

    - by PhilSando
    I was recently introduced to microsoft's tool that analyzes managed code assemblies called FxCop. It points out possible design, localization, performance, and security improvements against a pre defined set of rules (and also accepts custom rules). At first I was unsure how to go about using it as it seems to be aimed at software developers (.exe and .dll) . Its easy to get around this with the following steps: 1)Create a new folder (i.e C:\Code Analysis) 2)Publish your web application into the new folder 3)Open FxCop and add all the dll files from the newly created bin folder  to be scrutinized. Lots more info / docs available here on msdn and you can also download fxcop free

  • totally stuck trying to SSHing remote server

    - by user9609
    Hey guys, So i've been given access to ssh a server. I have the username/password, but server apparently requires a public key (now bear in mind that i am a noob in ssh). When I do: ssh -p 52 [email protected] terminal says Permission denied (publickey). So I went using ssh-keygen -t rsa and got myself the id_rsa and id_rsa.pub files in /root/.ssh. Chmoded /root/.ssh to 700 and /root/.ssh/* to 600. Tried sshing server.com again, same error. What am I missing? I've been given a Putty Pagant Key file (.ppk) by the SYSADMIN of server.com. Apparently, other users (all Windows) can connect using Putty Pagant.exe. Please help :)

  • Login and redirect to user home page [migrated]

    - by Rich
    The problem I can't currently solve is when a user logs in. They arrive at the site (index.php) and enter username and password, which gets submitted via a Post form back to index.php - if there are incorrect details then they get an error message. But if successful then I would like them to be taken to their user home page - but I can't do this! I am left presenting them with a link to the home page, which is more than a little clunky. Seems there must be an obviously solution - never seen a site before that didn't redirect! Not sure is the answer is PHp, HTML, or Javascript.

  • Speaking in Omaha: December 7, 2011

    - by Bill Graziano
    I’m presenting in Omaha on Writing Faster SQL at 6PM on December 7th.  You can find meeting details on the Omaha SQL Server User Group page. The meeting location requires an RSVP so building security has a list of attendees. The presentation is a series of suggestions on improving performance.  It ranges from simple things like comparing indexed columns to scalar values up to tips for reducing query compiles and asynchronous processing patterns.  Nearly all of these come from specific issues I’ve encountered working on poorly performing SQL Servers.

  • usb keyboard works except in terminal window (SOLVED)

    - by matrixunloaded
    I just installed 12.10 (clean install and updates). USB keyboard and mouse work fine EXCEPT the keyboard does not work in a terminal window (USB mouse is working in terminal). keyboard is Logitech MK320 and associated mouse. I'm typing in a mozilla window on the keyboard at this very moment and when I switch to the terminal window, nothing can be typed. Any ideas? I use terminal mode alot. Thanks matrixunloaded I didn't realize passwords do not show even an asterisk in terminal mode! I'd just installed 12.10 and was pasting a long sudo command and then typing my password (which looked like nothing appearing)

  • How to get KeePass to properly work with Chromium?

    - by Tom
    The two-channel auto-type obfuscation feature of KeePass doesn't work for me with Chromium (on Ubuntu 12.04 64 bits). However, it works just fine with Firefox. Dows anyone know how to fix this? Textboxes in web forms in Chromium seems to have something special that causes this feature to fail. Only some of the username/password characters are being auto-typed. This might be related to this: if I select an entry in KeePass and click "Copy User Name", I can paste it fine with Ctrl+V in any textbox in Firefox, but I can't on Chromium. However, text copied using Ctrl+C from a regular text file (say, from gedit), can be pasted fine on both browsers. What may be wrong? I wouldn't like to deactive this feature for all the entries in my keepass files as I use them on Windows too and they work just fine there (even on Google Chrome for Windows). This feature gives an appreciated extra security measure against spyware/keyloggers.

  • Mozilla Firefox 23 Will Block Mixed SSL Content

The default setting of Firefox 23 will block the content that called on non-https address and page is based on SSL. for example script using https://code.jquery.com/jquery-1.10.2.min.js will not work because code.jquery.com can not be reach on https. the cdn ajax.googleapis.com support SSL so you can try it. if you want to disable this settings you can modify it on about:config security.mixed_content.block_active_content change the value true to false and it will be disable (it’s just for example)

  • Climbing the hacker ladder

    - by cobie
    This is not a question in which I am asking for opinions rather I am asking for first hand experience. I have been programming in python for quite a while and I feel solid enough in python programming. I can come up with algorithms for problems and implement them but I somehow feel I am stuck with remaining an apprentice. What are some first hand experiences on how to climb up the ladder and become better at programming as in learning about browsers security, compilers etc. Personal experiences would be valued in responses.

  • How can I prevent people from looking at a listing of files in parent directory if I haven't uploaded index.html? [closed]

    - by LedZeppelin
    Possible Duplicate: How to restrict the download of all files in a folder? I haven't uploaded index.html or index.php to my root directory. How can I prevent people from looking at a listing of files in parent directory? http://oi56.tinypic.com/sc739e.jpg Also, is it possible for people to obtain a list of all the files in the root directory once I upload index.html? I'm currently using .htaccess and htusers to prompt someone to enter a username and password when they try to access any file in the root directory. This may sound like a weird request but would it be possible to have them come to the site (without an index.html) and just have them not see the files? All it would say on the page would be the following: Index of/ Apache Server at mysite.com Port 80

  • Ubuntu 12.04 freezing on startup

    - by Frank
    Have been looking everywhere to find a solution to this problem but have yet to find a solution. I am running 64 bit 12.04 LTS on a AMD C-50 Dual core 6 gigs ram AMD Ratheon HD 6250. The problem I am experiencing is when ubuntu gets to the wallpaper screen it will sometimes freeze soon after the the image appears or shortly there after gnome loads locking up keyboard and mouse. When I try to log in via the console the same thing happens (this is as ubuntu is loading). At the moment the system is set to auto login previously it was set to ask for password but it did the same thing. Switching to from lightdm to gdm did nothing to alleviate the issue. I have never had so many issues with ubuntu I have to say 12.04 is the most buggy version yet.

  • How can I remove bluetooth-applet in 11.10?

    - by dunderhead
    I tried adding rfkill block bluetooth to /etc/rc.local. This did not work. I tried adding both blacklist bluetooth and blacklist btusb to etc/modprobe.d/blacklist.conf. This did not work. So I went to Synaptic to remove it altogether, but when I marked bluez for removal it said it was going to also remove gnome-shell as well! So naturally I didn't do that. (Is it sane to run a potential security problem like bluetooth by default? And why is something like that so tightly integrated into Gnome shell?) Can anyone tell me how to get rid of this annoying and unnecessary process?

  • Ubuntu 12.10 WiFi Problems

    - by Sean Webber
    I have a 32 bit machine running Ubuntu 12.10 with WiFi on it. I have a WPA2 network at home, but if I leave the USB Adapter plugged in while it boots, it infinitely keeps asking for the network password but never connects. If I plug it in after boot, it will connect but then I can't access ANYTHING on the LAN or Internet because "the DNS servers are unreachable". Now, if I leave the computer on a while, I get lucky sometimes and it MAGICALLY decides to connect for a little bit, lock the machine though and the Internet's gone again. The weirdest thing, is when I am connected but can't get to the internet, I do a netstat or ifconfig wlan0, I do have an IP address and everything. It says I'm connected but its not. I have a Realtek RTL8188CU USB adapter.

    I installed Ubuntu 11.10 recently. After the first bootup the computer freezes so I have to force-quit my computer. Then I turned on my computer after that. I tried connecting to the internet. My (and my neighbor's) wireless networks shown up, but no matter how many times I tried, I can't connect to my home network. I checked the password and the other laptop's internet works (a MacBookPro). It was a wireless network. What's weird is that the Wireless network worked when I was installing ubuntu How can I connect to the internet now? I don't have a wired network. Please Help! Any help will be appreciated Specs: ASUS F81Se, Windows 7 Dual-boot, I remember the wireless card was made by Atheros, 4GB RAM

  • What You Said: How Do You Set Reminders?

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your favorite tricks for staying on top of your tasks with timely reminders. Now we’re back to highlight some great reader tips (including a bit of software older than some of our readers). Most of us have to-do lists longer than we can do in a given day (or week!) and a constantly changing set of demands and next-actions. Having a timely and effective reminder system is the difference between dropping the ball and getting things done; how exactly that reminder system plays out, however, varied greatly from reader to reader. OJMDC sticks with analog reminders: Sticky notes in the middle of my monitor and in my wallet. I’ve tried my phone apps but I typically disregard them. HTG Explains: Is UPnP a Security Risk? How to Monitor and Control Your Children’s Computer Usage on Windows 8 What Happened to Solitaire and Minesweeper in Windows 8?
