  • Ubuntu12.10 not installing on new computer?

    - by Joshua
    I'm trying to Install the latest 12.10 Desktop. I have burned the iso file onto a DVD using an ISO burner. I then reboot my computer, and use the boot menu, I choose the DVD and it asks me if I want to try it, install it, or check for defects. Whichever one I choose my screen goes blank and for a bit you can hear my DVD burner, but then it stops and the screen goes completely blank and doesn't so anything. I am using a new HP Pavilion model P7-1455 running windows 8. What is wrong? How can I fix this?

  • Is there a Windows 7 equivalent to the *NIX ability to create a hard link to /dev/null?

    - by minameismud
    I saw another question here that the Windows equivalent to /dev/null is simply NUL. I also know that you can use the mklink command to make sym links (shortcuts) from the command line: MKLINK [[/D] | [/H] | [/J]] Link Target /D Creates a directory symbolic link. Default is a file symbolic link. /H Creates a hard link instead of a symbolic link. /J Creates a Directory Junction. Link specifies the new symbolic link name. Target specifies the path (relative or absolute) that the new link refers to. When I try to use the /j switch to make a hard link ("junction") instead of a simple shortcut to NUL, I get: C:\>mklink /j "C:\Program Files\MyNewHardlinkFolder" NUL Local volumes are required to complete the operation. I can create shortcuts to NUL all day long using the /d switch, but I would much prefer the hard link. Any ideas?

  • How do I shutdown 12.10 when ACPI is set to OFF?

    - by rahi
    I recently installed 12.04 on an HP Spectre XT ultrabook. I installed 12.04 from a USB. When the install was complete, and the computer restarted, I got a blank screen. After some searching, I found that I had to choose "acpi=off" during the installation, which now shows up in the grub screen. Once I was on 12.04, I upgraded to 12.10. The issue now is that when I hit shutdown, the computer hangs on a purple shutdown screen. Usually, at this point, I press the power button on the machine to completely power off the machine. I am new to ubuntu, and would appreciate the help. Thanks.

  • Commands don't have permission when using absplute path

    - by Markos
    I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance.

  • Ubuntu 13.10 alongside Windows 7 - Mission Impossible?

    - by Przemek Jedlikowski
    I just want to install Ubuntu 13.10 alongside Windows 7 HP on my EeePC 1215N. I can't do it when Windows 7 is booted up (wubi.exe hasn't got that option), so I booted it from USB key. Everything's loaded, I double-click Install Ubuntu. I click 'Next ', then I choose that I want to install Ubuntu alongside Windows 7. And the machine restarts. Not resets. Restarts. X server's killed immediately, I can see the console only. What do I have to do now?

    - by Filkor
    When I try to boot from my USB it says: (initramfs) unable to find a live medium containing a live file system I know of lots of questions here about this problem... I've tried every solution but nothing worked. I just ask if anyone here who got a Toshiba Sattelite Pro c650 and found the solution, because I simply cant install Ubuntu 10.04 because of this :((( Other spec: - I have USB 2.0 - Changed all possible settings in BIOS. (AHCI..) - ISO is not corrupted (boot is succesful on my other HP Laptop) Thanks. Edit: But XUbuntu works :/

  • Bizarre SSH Problem - It won't even start

    - by thallium85
    I recently got Ubuntu 12.04 Precise, got it up and running with some MediaWiki software, static IP on the box and router and was able to access the main page even from a cell phone. Everything seemed great... Then I wanted to finally get rid of the monitor and keyboard and login remotely via SSH. I installed openssh-server, let everything point to port 22 for a test run and installed putty on my Windows XP machine. I got a connection refused. Went back and started checking the Ubuntu install itself... (I'm under root from this point on) $ sudo -s $ service ssh status ssh stop/waiting $ service ssh start ssh start/running, process 2212 $ service ssh status ssh stop/waiting Apparently ssh has stopped or is waiting for something.... $ ssh localhost ssh: connect to host localhost port 22: Connection refused I can't even connect to myself... I checked ufw (firewall) to see if port 22 is doing alright... $ sudo ufw status Status: active To Action From 22 ALLOW Anywhere 22/tcp ALLOW Anywhere 22 ALLOW Anywhere (v6) 22/tcp ALLOW Anywhere (v6) sshd_config shows only Port 22 Is ssh not using the right IP address at all? I just don't get what I did wrong here. When this is up and running I will def change the port number, but for now, I don't want to mess with the default install too much until a test run with putty is successful. Edit: Here are my sshd_config file and my ssh_config file. The command /usr/sbin/sshd -p 22 -D -d -e returns: /etc/ssh/sshd_config line 159: Subsystem 'sftp' already defined. Edit: @phoibus moving the sshd_config file and reinstalling did the trick! service ssh status the above command shows that ssh is now running and I am now able to log in from my windows xp computer remotely via putty. Thanks so much! I can now use my monitor for other things!

  • Installing Ubuntu 12.10 on new computer with Windows 8

    - by rft183
    I recently purchased a new HP computer (P6-2330) with Windows 8. I have tried unsuccessfully to install Ubuntu 12.10 64bit alongside Windows 8. The computer is UEFI with Secure Boot enabled. I've tried following the instruction at https://help.ubuntu.com/community/UEFI. I am able to get the GRUB menu to show up. However, as soon as I press Enter on either Try Ubuntu or Install Ubuntu, the screen goes blank. Nothing works at all, not even the Num Lock or Caps Lock keys on the keyboard. I have to use the power button to restart the computer. Does anyone have any suggestions on how to get Ubuntu installed? To clarify, I have actually tried installing using both a USB stick and a DVD. The USB stick gave a blank screen, while the DVD gave the error message "Empty Security Header" after pressing Enter at the GRUB screen.

  • Screen resolution higher than monitor specs

    - by bisi
    Is there any magical or non-magical way to increase screen resolution for my monitor that officially does 1366 x 768? With my graphics card, I could do 1920, and when I actually do that, the image is very "unclean" on the screen... I run Ubuntu 10.10, on an HP Pavilion with a GeForce 315. My monitor is a HD ready Samsung LE32C450... my smaller previous monitor had no problem showing a 1920 resolution, and my obvious mishap was to assume a much bigger screen would support at least this same resolution... Any tips would be greatly appreciated!

  • What is wrong with my expect script?

    - by Bryan
    I'm trying to learn how to use the expect command, to help me automate deployment of some software via shell scripts, and figured I start with something simple to get me started. I've created a file in my home dir called 'foo' using: touch foo And I've created the following script saved as test.exp #!/usr/bin/expect spawn rm -i foo expect "rm: remove regular empty file `foo'?" send "y\r" When I run the script using ./test.exp, it spawns the rm command, but it doesn't appear to send the Y and carriage return. I know I don't have a typo in the expect string, as I've used copy and paste to put in the script. What am I doing wrong?

  • Colored PS1 string

    - by Will Vousden
    Clarification: I want __foo to be executed each time the PS1 string is presented in the terminal, not when the PS1 string is constructed (hence its being in quotes). __foo contains logic that examines the current directory, so its execution must be deferred. I'm trying to use different colours in my Bash PS1 string from within a Bash function: LIGHTRED="\033[1;31m" LIGHTGREEN="\033[1;32m" RESET="\033[m" __foo () { # Do some stuff and genereate a string to echo in different colours: echo -n '\['$1'\]firstcolour \['$2'\]secondcolour' } PS1='$(__foo '$LIGHTRED' '$LIGHTGREEN')\['$RESET'\] \$' Essentially I want __foo to generate part of the PS1 in a bunch of different colours. My attempt doesn't seem to work, though; it produces the following output: -bash: 31m: command not found -bash: 32m: command not found \[]firstcolour \[\]secondcolour $ What gives, and how can I fix it?

  • How to pipe differently the body of the curl answer and the printed output?

    - by Antoine Lizée
    I would like to print in the command line some output of curl, like the http headers, followed by the body of the answer processed by a stdin/stdout program. For instance: Print the status code: curl -s -w "%{http_code} \\n" -o "/dev/null" http://myURL.com And then process the output with a json parsing tool: curl -s http://myURL.com | python -mjson.tool I would like to do both with one command, and I have the feeling that it may be possible thanks to the -o option that makes the difference between the output of curl and the actual answer from the query. The problem is that -o writes directly to a file. Somebody's got a hack?

  • How to rsync a large file, with as little CPU and bandwidth expense as possible?

    - by Johan Allgoth
    I have a 500 GB file that I plan on backing up remotely. The file changes often. I'll be rsyncing it from a desktop to a server. Both can run rsync client or server. What is the proper command for this? The ones I've tried sofar has been taking forever or simply acted strange. Example and results: rsync -cv --partial --inplace --no-whole-file /desktop/file1 myserver.com::module/file1 Seems to work, but only if I do it twice (?!). Also, slow. Does the above command do the checksumming on both computers, or only on the sending one? Is it correct otherwise?

  • Who keeps removing that file?

    - by mgerdts
    Over the years, I've had many times when some file gets removed and there's no obvious culprit.  With dtrace, it is somewhat easy to figure out:  #! /usr/sbin/dtrace -wqs syscall::unlinkat:entry /cleanpath(copyinstr(arg1)) == "/dev/null"/ {         stop();         printf("%s[%d] stopped before removing /dev/null\n", execname, pid);         system("ptree %d; pstack %d", pid, pid); } That script will stop the process trying to remove /dev/null before it does it.  You can allow it to continue by restarting (unstopping?) the command with prun(1) or killing it with kill -9.  If you want the command to continue automatically after getting the ptree and pstack output, you can add "; prun %d" and another pid argument to the system() call.

  • No sound after clean install

    - by John Cheednik
    Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

  • How can I change ACLs recursively using cacls.exe?

    - by maaartinus
    I want to restrict the access for everything inside the work directory to me and the system only. I tried this with the following command: cacls.exe work /t /p 'PIXLA09\Maaartin:f' 'NT AUTHORITY\SYSTEM':f However it doesn't work at all. The following command should show only the two specified users but instead shows a very long list of permissions: cacls.exe work/somedirectory I tried to use /g instead of /p, too. Since I didn't use /e the permissions shouldn't get edited but replaced. Any ideas what's wrong?

  • How do I SCP/FTP to a Coraid SR2421

    - by Pitto
    I need to save data to a Coraid SR2421. I am no expert and I'm trying to understand how this costy piece of hardware works. All I have is a Ethernet cable connecting my laptop and the coraid to a switch and the coraid's console with cursor blinking. Any kind of help would be greatly appreciated. edit and further explanation: I've tried using software on the coraid website but It's not working. So I've contacted the support and they sent me a file to upload on the coraid. It looks like if I upgrade coraid's firmware then I'll be able to use the coraid software on the windows side. That's why I'd need SCP/FTP or any kind of solution to copy a file in the partition that can be read from coraid console command line so I can launch the update command as requested. I hope I was a bit clearer now.

  • tunneling x11vnc through ssh on a non standard port to ubuntu computer tightvnc

    - by user72372
    I have been stuck with setting up my virtual desktop on my ubuntu laptop. I am running ubuntu to ubuntu with x11vnc I start the process on my laptop as follows: " ssh -L5904:localhost:5900 -p Port remoteuser@remoteip." That command works, then I start x11vnc server, "x11vnc -noncache -once -shared -rfbauth ~/.vnc/passwd." This command works and starts connection. Then I open another window on my laptop and type, export VNC_VIA_CMD='/usr/bin/ssh -2 -c aes128-cbc -x -p Port -l User -f -: %L:%H:%R %G sleep 20' (not sure if works). then I type, vncviewer -endcodings Tight -depth 8 -quality 1 -via IPofremotemachine -u remoteuser localhost:01. The first time it work but from now on it just gives me the vncviewer -help screen everytime. I type in the password for my remote machine and then shows -help screen for vncviewer. I think the problem is with Tightvnc viewer but don't know what. Please help. I got some info on www.vanemery.com/Linux/VNC/vnc-over-ssh.html?.

  • Pause and Resume and get the value of a countdown timer by savedInstanceState [closed]

    - by Catherine grace Balauro
    I have developed a countdown timer and I am not sure how to pause and resume the timer as the TextView for the timer is being clicked. Click to start then click again to pause and to resume, click again the timer's text view. This is my code: Timer = (TextView)this.findViewById(R.id.time); //TIMER Timer.setOnClickListener(TimerClickListener); counter = new MyCount(600000, 1000); }//end of create private OnClickListener TimerClickListener = new OnClickListener() { public void onClick(View v) { updateTimeTask(); } private void updateTimeTask() { if (decision==0){ counter.start(); decision=1;} else if(decision==2){ counter.onResume1(); decision=1; } else{ counter.onPause1(); decision=2; }//end if }; }; class MyCount extends CountDownTimer { public MyCount(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); }//MyCount public void onResume1(){ onResume(); } public void onPause1() { onPause();} public void onFinish() { Timer.setText("00:00"); p1++; if (p1<=4){ TextView PScore = (TextView) findViewById(R.id.pscore); PScore.setText(p1 + ""); }//end if }//finish public void onTick(long millisUntilFinished) { Integer milisec = new Integer(new Double(millisUntilFinished).intValue()); Integer cd_secs = milisec / 1000; Integer minutes = (cd_secs % 3600) / 60; Integer seconds = (cd_secs % 3600) % 60; Timer.setText(String.format("%02d", minutes) + ":" + String.format("%02d", seconds)); //long timeLeft = millisUntilFinished / 1000; }//on tick }//class MyCount protected void onResume() { super.onResume(); //handler.removeCallbacks(updateTimeTask); //handler.postDelayed(updateTimeTask, 1000); }//onResume @Override protected void onPause() { super.onPause(); //do stuff }//onPause I am only beginner in android programming and I don't know how to get the value of the countdown timer using savedInstanceState.

  • Open a custom remote powershell remotely

    - by Yann
    I have 2 computers. On the computer A, I have a custom module written in C# for powershell 3.0 and installed via a MSI. I also have a shortcut that open powershell with the module already loaded. I can just double click on my shortcut and run my command Do-Something on this computer without any problem, like the Exchange Server powershell. But now I would like to do it from a remote session on computer B in C#. So my question is, how can I open a remote powershell session to computer A with my module already loaded and the shell configured so I can just run my command and obtain the same result than if I run it on computer A?

  • Added autossh in rc.local, but the dynamic port forwarding won't work

    - by rankjie
    I am using Rasbian on my newly arrived Rasp.Pi, and decided to make it my own proxy server. Now I need to set up a ssh tunnel on the Pi to my Linode server, and make it auto start with the system. What did I do: Add this line to /etc/rc.local autossh -f theRemoteServer -N -D 5555 -L 1234:localhost:22 After I reboot, I found out that I can't use the localhost:5555 as a socks proxy. So I type the command ps -A | grep ssh then I can see the autossh and ssh all running: pi@raspberrypi ~ $ ps -A | grep ssh 2018 ? 00:00:00 sshd 2116 ? 00:00:00 autossh 2119 ? 00:00:00 sshd 2195 ? 00:00:00 sshd 3173 ? 00:00:00 ssh (I've installed autossh, and the command works if I type it manually.) (I use the passwordless key auth, so I don't have to enter password.) Much appreciated and sorry for my poor English.
