  • 12.04 Booting into Terminal

    - by user170796
    To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

  • How do I get mouse x / y of the world plane in Unity?

    - by Discipol
    I am trying to make a tiled landscape. The terrain itself is not made from tiles but the world has a grid which I define. I would like to place boxes/rectangles which snap to this grid, at runtime, but in order for me to do that I must get a projection from the user screen to the real-world coordinates. I have tried various examples using the Ray class but nothing worked. It compiles and outputs a constant value no matter where I put the mouse. I have tried to add some tiles and try to detect them but no luck. I also tried with one plane as big as my world but still no luck. I am using C# but even a JS version would be helpful. This technique involves calculating which tile the mouse is under by the x and y positions. Perhaps detecting which tile itself is being pointed to would be a simpler task, at which point I can just retrieve its i/j properties. Update: I got it working thanks to some answers, but the ball freaks out towards the far end of the plane. Why is this? https://www.dropbox.com/sh/9pqnl30lm6uwm6h/AACc2JcbW16z6PuHFLLfCAX6a

  • Windows 8.1 erased Ubuntu 14.04 partition

    - by Caumons
    I had Ubuntu 14.04 installed with a Windows 7 dual boot. Now, I've just replaced W7 by Windows 8, but the Ubuntu partition has disappeared! Running fdisk -l doesn't show /dev/sda5 (which was the Ubuntu partition), if I access to Gparted, it shows the Ubuntu partition as "empty space" and from Windows 8's device manager, this partition also appears as empty space! WTF has happened here? Has the partition been actually erased?

  • Your Presence Matters at the PASS Summit

    - by AllenMWhite
    This year will be my tenth year attending the annual PASS Summit. It's in Seattle again this year, which to me is important because of the proximity to the Microsoft offices and the people on the SQL Server dev team, as well as the CX (formerly CAT) teams that help so many people get the most out of SQL Server. The conference is the biggest event in the world specifically focused on SQL Server. As a result, it's an opportunity to meet many people who are directly focused on the SQL Server platform,...(read more)

  • Howto prevent grubpc 2.02 to display with submenu?

    - by useful
    In the past, we could tweak grub-pc so that it simply shows all OSes/options as a simple list, slightly editing /etc/grub.d/10_linux. How can we do that in the 2.02~beta2-9 release supplied with Trusty Tahr 14.04? With several kernels installed (eg generic and lowlatency) submenu is boring with such a /etc/default/grub when I need to change OS: GRUB_DEFAULT=saved GRUB_SAVEDEFAULT=true GRUB_TIMEOUT=3 # GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux" GRUB_CMDLINE_LINUX="" Thank you

  • Ubuntu boot hangs after message "Running /scripts/init-bottom ... done"

    - by Douglas B. Staple
    I've been trying to copy a Proxmox container based on the Ubuntu Precise Standard template to a VirtualBox VM. I am now stuck at a point where my new Ubuntu/VirtualBox VM hangs after the message "Running /scripts/init-bottom ... done" during boot. I started by installing Ubuntu Server 12.04.4 LTS on a VirtualBox VM. Ubuntu Server 12.04.4 LTS was the closest "official" Ubuntu ISO to the Proxmox container OS I could find. I installed all updates on both the Proxmox container and on the VirtualBox VM. The idea was to get same version kernal running on the ProxMox container and VirtualBox VM. sudo apt-get update ; sudo apt-get upgrade ; sudo apt-get dist-upgrade sudo reboot rsync the entire proxmox container to a temporary directory in the VirtualBox VM: cd / mkdir /tmp/backup rsync -e ssh -av --exclude={/dev,/proc,/sys,/tmp,/run,/mnt,/media,/lost+found,/boot,/selinux} root@my_proxmox_container_hostname:/ /tmp/backup Shut down the virtual machine, and boot the VM with a bootable linux image. I used the Desktop image of Ubuntu 12.04 LTS, ubuntu-12.04.4-desktop-i386.iso Drop to a root prompt. Mount the VM root filesystem: sudo mount /dev/sda1 /mnt Remove files from most of /mnt cd /mnt sudo rm -rf bin etc home lib opt sbin root usr var Move all of the files from /mnt/backup into /mnt sudo mv /mnt/tmp/backup/* /mnt Rebooted system. For me, at this point the system freezes after starting, after the message: Running /scripts/init-bottom ... done I've tried reinstalling GRUB and all manner of other thing. I am almost ready to give up.

    Hello, So I'm stuck with this directory: drwxrwxrwx 2 dan users 980M 2010-12-22 18:38 sessions2 The directories contents is small - just millions of tiny little files. I want to wipe it from the filesystem but have been unable to. My first try was: find sessions2 -type f -delete and find sessions2 -type f -print0 | xargs -0 rm -f but had to stop because both caused escalating memory usage. At one point it was using 65% of the system's memory. So I thought (no doubt incorrectly), that it had to do with the fact that dir_index was enabled on the system. Perhaps find was trying to read the entire index into memory? So I did this (foolishly): tune2fs -O^dir_index /dev/xxx Alright, so that should do it. Ran the find command above again and... same thing. Crazy memory usage. I hurriedly ran tune2fs -Odir_index /dev/xxx to reenable dir_index, and ran to Server Fault! 2 questions: 1) How do I get rid of this directory on my live system? I don't care how long it takes, as long as it uses little memory and little CPU. By the way, using nice find ... I was able to reduce CPU usage, so my problem right now is only memory usage. 2) I disabled dir_index for about 20 minutes. No doubt new files were written to the filesystem in the meanwhile. I reenabled dir_index. Does that mean the system will not find the files that were written before dir_index was reenabled since their filenames will be missing from the old indexes? If so and I know these new files aren't important, can I maintain the old indexes? If not, how do I rebuild the indexes? Can it be done on a live system? Thanks!

  • "Could not claim interface on camera: -6" when trying to connect usb camera (Kinect)

    - by rzetterberg
    I have installed the freenect library from openkinect.org. With that library there is a demo application which you can run from the terminal to test out the Kinect. However when I run this command I get the following output: richard@behemoth:~$ sudo freenect-glview Kinect camera test Number of devices found: 1 Could not claim interface on camera: -6 Could not open device This particular error is thrown by the library libusb by the function libusb_claim_interface and the error -6 corresponds to the LIBUSB_ERROR_BUSY. So my guess is that it has something to do with mounting the usb, rather than specifically the freenect library or the Kinect itself. So my question is how can I find out what resource is using this interface and how can I free it so that I can access it? Edit: What I have tried so far (just to be sure): Rebooted Plugged-out, plugged-in Tried different usb ports Restarted udev Additional information that might be useful: /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

  • OpenSSL support for Ruby: "Cipher is not a module (TypeError)"

    - by smotchkkiss
    The Problem Our systems admin needed to upgrade the packages on our CentOS 5.4 dev server to match the packages on our production server. The upgrade affected ruby and/or openssl. We run a Ruby on Rails issue tracking system called Redmine that is deployed with Passenger on Apache. Everything worked before the server update, but when trying to access the ticket system now, I get the following error: Error message: Cipher is not a module Exception class: TypeError Application root: /home/dev/rails/redmine-0.8.7 I've been trying so hard to fix this problem but I can't seem to beat it. I have tried following this guide: http://iamclovin.posterous.com/how-to-solve-the-cipher-is-not-a-module-error When I try require 'openssl' in IRB, I do see a true return value. However, I'm still seeing the Cipher.rb is not a module TypeError when accessing the ticket system. Possibly (probably) related: I've tried updating Passenger, but when I try passenger-install-apache2-module I see: Checking for required software... * GNU C++ compiler... found at /usr/bin/g++ * Ruby development headers... found * OpenSSL support for Ruby... /usr/lib/ruby/1.8/openssl/cipher.rb:22: Cipher is not a module (TypeError) Any help?

  • Problems setting up a VPN: can connect but can't ping anyone

    - by Fernando
    This is my first time setting a VPN. Clients can connect but can't ping other machines. This is certainly a route problem but i can't find the right way to configure it. Here is a sample example of the two LANS i want to connect: So, i want machines from 192.168.1.0/24 being able to connect with 192.168.0.0/24 as if they were on the same network. For the VPN network, i would like to use the 10.0.0.0/24 range. Here is my server.conf: proto udp port 1194 dev tun server 10.0.0.0 255.255.255.0 push "route 192.168.0.0 255.255.255.0 192.168.0.1" push "dhcp-option DNS 192.168.0.1" push "dhcp-option WINS 192.168.0.1" comp-lzo keepalive 10 120 float max-clients 10 persist-key persist-tun log-append /var/log/openvpn.log verb 6 tls-server dh /etc/openvpn/keys/dh1024.pem ca /etc/openvpn/keys/ca.crt cert /etc/openvpn/keys/server.crt key /etc/openvpn/keys/server.key tls-auth /etc/openvpn/keys/mykey.key 0 status /var/log/openvpn.stats And one of my clients 192.168.1.2: client dev tap proto udp remote my.no-ip.address 1194 route 192.168.1.0 255.0.0.0 192.168.1.1 3 resolv-retry infinite nobind persist-key persist-tun ca "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ca.crt" cert "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\test1.crt" key "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\test1.key" tls-auth "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\mykey.key" 1 ns-cert-type server cipher BF-CBC comp-lzo verb 1 What exactly i am doing wrong?

  • How to configure postfix for per-sender SASL authentication

    - by Marwan
    I have two gmail accounts, and I want to configure my local postfix server as a client which does SASL authentication with smtp.gmail.com:587 with credentials that depend on the sender address. So, let's say that my gmail accounts are: [email protected] and [email protected]. If I sent a mail with [email protected] in the FROM header field, then postfix should use the credentials: [email protected]:psswd1 to do SASL authentication with gmail SMTP server. Similarly with [email protected], it should use [email protected]:passwd2. Sounds fairly simple. Well, I followed the postfix official documentation at http://www.postfix.org/SASL_README.html, and I ended up with the following relevant configurations: /etc/postfix/main.cf smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sender_dependent_authentication = yes sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay smtp_tls_security_level = secure smtp_tls_CAfile = /etc/ssl/certs/Equifax_Secure_CA.pem smtp_tls_CApath = /etc/ssl/certs smtp_tls_session_cache_database = btree:/etc/postfix/smtp_scache smtp_tls_session_cache_timeout = 3600s smtp_tls_loglevel = 1 tls_random_source = dev:/dev/urandom relayhost = smtp.gmail.com:587 /etc/postfix/sasl_passwd [email protected] [email protected]:passwd1 [email protected] [email protected]:passwd2 smtp.gmail.com:587 [email protected]:passwd1 /etc/postfix/sender_relay [email protected] smtp.gmail.com:587 [email protected] smtp.gmail.com:587 After I'm done with the configurations I did: $ postmap /etc/postfix/sasl_passwd $ postmap /etc/postfix/sender_relay $ /etc/init.d/postfix restart The problem is that when I send a mail from [email protected], the message ends up in the destination with sender address [email protected] and NOT [email protected], which means that postfix always ignores the per-sender configurations and send the mail using the default credentials (the third line in /etc/postfix/sasl_passwd above). I checked the configurations multiple times and even compared them to those in various blog posts addressing the same issue but found them to be more or less the same as mine. So, can anyone point me in the right direction, in case I'm missing something? Many thanks.

  • Debian and Multipath IO problem

    - by tearman
    Basically the situation is, I have a box running Debian, the box internally has an Intel SCSI RAID controller which is controlling 2 hard drives in RAID1 mode which is where the OS is installed. Further, I have a QLogic fiber channel adapter that connects the unit to a Fiber Channel SAN. My process of installation is I'll install Debian to the local drives, and leave the QLogic firmware out of it for the time being. Then once I get the unit online, I'll install the firmware drivers. This flops my internal drives from /dev/sda to /dev/sdc, which is a bit annoying, but recoverable. Probably should address these by UUID anyways. Once I get back online, I have to install multipath-tools (the framework is a multipath framework). However, once I reboot the machine again, it fails on boot after discovering multipath targets, saying my local drives are busy and cannot be mounted to /root. Any help in what may be the problem here? Or at least how to disable multipath until after the unit boots and then ignores the internal drives?

  • Why can’t two programs access my webcam simultaneously?

    - by qdii
    I first launch cheese and my webcam turns on. I then run vlc to grab the output of /dev/video0 but it fails with: [0x7f3ea40012e8] v4l2 demux error: cannot set input 0: Device or resource busy [0x7f3ea40012e8] v4l2 demux error: cannot set input 0: Device or resource busy [0x7f3ea4002168] v4l2 access error: cannot set input 0: Device or resource busy [0x7f3ea4002168] v4l2 access error: cannot set input 0: Device or resource busy [0x7f3eb4000b78] main input error: open of `v4l2:///dev/video0' failed Whatever pair of video programs I run (skype, cheese, vlc, etc.), the result is always the same: the second program can no longer use the webcam when the first one has already grabbed the output. However I find it curious as video4linux states: In general, V4L2 devices can be opened more than once. When this is supported by the driver, users can for example start a "panel" application to change controls like brightness or audio volume, while another application captures video and audio. My webcam is seen in lspci as 058f:a014 Alcor Micro Corp. Asus Integrated Webcam, but I don’t even know what the underlying driver is, so I can’t check whether my problem is driver-related or not. Any input would be more than welcome!

  • OpenVPN Bridge LAN-to-LAN Configuration?

    - by Shad Reese
    I'm trying to configure an OpenVPN bridge LAN-to-LAN setup. Currently, I have the OpenVPN bridge Server/Client setup up running. On the server-side my br-lan interface has tap0, eth0, and wlan0 in the bridge group. On the client-side the br-lan interface has eth0 and wlan0 in the bridge group, the client tap0 is outside of the br-lan group. Currently the two bridge groups are connected via the wlanO interfaces (server-side is the Access Point - AP and the client-side is the wireless client). My goal is to connect the two bridge groups with a wireless VPN pipe. My network configuration: Server: br-lan: 10.4.96.50 Client: br-lan: 10.4.96.75 tap0: 10.4.96.100 <---- issued by the VPN server. Unfortunately, I'm stuck with using a bridge instead of a routed OpenVPN setup. My question is how (if possible) do I add the client tap0 interface to the client bridge group, as to ensure all traffic between the server/client bridge groups is using the VPN pipe? SERVER CONFIG FILE. config openvpn sample_server # Set to 1 to enable this instance: option enable 1 option port 1194 option proto udp option dev tap0 option key /etc/easy-rsa/keys/server.key option dh /etc/easy-rsa/keys/dh1024.pem option ifconfig_pool_persist /tmp/ipp.txt option server_bridge "10.4.96.50 255.255.255.0 10.4.96.100 10.4.96.200" list push "redirect-gateway local def1" list push "dhcp-option DNS 10.4.96.14" option duplicate_cn 1 option comp_lzo 1 option max_clients 100 option log /tmp/openvpn.log option verb 3 CLIENT CONFIG FILE: config 'openvpn' 'sample_client' option 'enable' '1' option 'client' '1' option 'dev' 'tap' option 'proto' 'udp' list 'remote' '10.4.96.50 1194' option 'status' /tmp/openvpn-status.log option 'log' /tmp/openvpn.log option 'ca' '/etc/easy-rsa/keys/ca.crt' option 'cert' '/etc/easy-rsa/keys/client.crt' option 'key' '/etc/easy-rsa/keys/client.key' option 'comp_lzo' '1' option 'verb' '5' Thanks in advance,

  • Citrix client slow to launch

    - by user706837
    Was wondering if anyone else experience Citrix client to launch very slowly. While I'm a Windows SA by trade, I consider myself Novice+ on Linux, but I doubt thats the problem. This is the simple scenario: 1. Login to Citrix server to work from home 2. Click on the published application; this typically starts the local Citrix client. 3. Citrix client should start and you're off. Problem is between #2 and #3 I click on the application and 8 out of 9 times there is a 60 second delay and then I get an SSL connection error. I suspect this error is misleading since the connection took too long to open. But I dont know how to prove it (or fix it). I'm able to successfully manually launch wfcmgr without errors; so this leads me to believe Citrix client is installed correctly. I even leave it running thinking this may help, but I don't see a difference with or without this running first. The only times I'm able to connect successfully is when the Citrix client starts up a few seconds after clicking on the application. I've searched online for articles that might help, but tried a number of fixes without much difference. Even tried "ln -sf /dev/urandom /dev/random" as suggested by this article, but no dice:http://forums.citrix.com/message.jspa?messageID=1381276 My System (specs that may be relevant) Sony VAIO Laptop VGN-NW270F Linux Mint 11.04 Problem using: FireFox and Chrome Any help would be appreciated. Just trying to either find an answer or guidance on how to determine why its taking so long to launch the Citrix Client. Thanks

  • How to run some commands after booting from ArchLinux disk? Or how to change some settings in .iso before booting?

    - by Alexander Ovchinnikov
    How to install Arch Linux with traditional installer with only ssh-access to server? There is nice guide: https://wiki.archlinux.org/index.php/Install_from_SSH I try test this on my home vps: Start VPS with any linux bootable cd and login to remote server (vps) wget http://mirrors.kernel.org/archlinux/iso/latest/archlinux-2010.05-netinstall-x86_64.iso dd if=archlinux-2010.05-netinstall-x86_64.iso of=/dev/sda reboot ... I see, it works but without ssh connection... I need make script, which will send this commands after reboot: aif -p partial-configure-network (and write some information about my server ip etc.) /etc/rc.d/sshd start (need to start sshd) echo "sshd: ALL" /etc/hosts.allow (to allow me login to server, by default deny all) passwd (by default its empty, can't login via ssh with empty password) Can I edit .iso or may be /dev/sda? May be I need write script, which will start after system boot and do this things or may be I can set this settings by default and system will start with correct settings (i think its possible at least in 2. and 3.). Thank you!

  • Openfiler iSCSI performance

    - by Justin
    Hoping someone can point me in the right direction with some iSCSI performance issues I'm having. I'm running Openfiler 2.99 on an older ProLiant DL360 G5. Dual Xeon processor, 6GB ECC RAM, Intel Gigabit Server NIC, SAS controller with and 3 10K SAS drives in a RAID 5. When I run a simple write test from the box directly the performance is very good: [root@localhost ~]# dd if=/dev/zero of=tmpfile bs=1M count=1000 1000+0 records in 1000+0 records out 1048576000 bytes (1.0 GB) copied, 4.64468 s, 226 MB/s So I created a LUN, attached it to another box I have running ESXi 5.1 (Core i7 2600k, 16GB RAM, Intel Gigabit Server NIC) and created a new datastore. Once I created the datastore I was able to create and start a VM running CentOS with 2GB of RAM and 16GB of disk space. The OS installed fine and I'm able to use it but when I ran the same test inside the VM I get dramatically different results: [root@localhost ~]# dd if=/dev/zero of=tmpfile bs=1M count=1000 1000+0 records in 1000+0 records out 1048576000 bytes (1.0 GB) copied, 26.8786 s, 39.0 MB/s [root@localhost ~]# Both servers have brand new Intel Server NIC's and I have Jumbo Frames enabled on the switch, the openfiler box as well as the VMKernel adapter on the ESXi box. I can confirm this is set up properly by using the vmkping command from the ESXi host: ~ # vmkping 10.0.0.1 -s 9000 PING 10.0.0.1 (10.0.0.1): 9000 data bytes 9008 bytes from 10.0.0.1: icmp_seq=0 ttl=64 time=0.533 ms 9008 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=0.736 ms 9008 bytes from 10.0.0.1: icmp_seq=2 ttl=64 time=0.570 ms The only thing I haven't tried as far as networking goes is bonding two interfaces together. I'm open to trying that down the road but for now I am trying to keep things simple. I know this is a pretty modest setup and I'm not expecting top notch performance but I would like to see 90-100MB/s. Any ideas?
