Ubuntu Servers :: Use F12 To Execute Script Even When Not Logged On
May 28, 2010
how to bind a script to a F key (F12) that will run as root even when not logged in. I have a headless server on client premises where it'd be easier for them to press F12 to run this script that will be rarely needed than to give them SSH instructions etc. I know this must be do-able, but I can't get my Google-fu on for this question. The only way that I can possibly think of doing it is to touch a file whenever that key is pressed and have the script idly checking for that file every few seconds in a loop.

I have the system setup and working, but I want to put it in a corner and forget about it. Problem is, nothing starts running unless I'm logged in. And if I log out, everything stops again.It's running a LAMP server and has VNC and SSH servers as well. I want all of that to start without having to log in. That way I can remote reboot without worries and connect and login with either VNC or SSH.Everything seems to have an entry in /etc/init.dIs the way it's acting normal behavior? It's a fresh install, then I installed everything I needed from the repos.

I'm a total Linux noob, but I've needed a working development server for a while so I've put together an old celeron box running Ubuntu Server 10.10.The box runs fine, as does the Apache and MySQL servers, even if they did take a little while to fine tune!The problem I have is that vsftpd doesn't respond unless I'm logged on locally or via putty. As long as a local user is logged in, it's fine. If I try to connect when noone is logged in, then the connection times out waiting for the server message, and thereafter I have to login and stop / restart the vsftpd to make it work again.I'm not sure if the vsftpd is set to run on boot or on login and I have no idea how to check. Vsftpd is set to allow only local users, of which there is only one - so I can't check if it would work with any user logged in

After a battle with Ubuntu, Django, Apache and wsgi i could reach the website i set up from another computer via ip-adress (10.37.129.6). i then restarted the server and after booting tried to access the website from outside - permission to / denied with the usual 403 error. trying to fix that, i logged in to the server and suddenly the website was available again. typed logout on the server - no access wt. 403. logged in - website can be accessed.i somehow suspect this is some strange permission problem, but i don't have a clue where to start searching. errorlogs just contain information that a / access request has been denied.

the apche2.conf and vhost file I gave the link are the machine on LAN when site is actually hosted.When some one from internet access the site then I expect a log of IP in access.log instead of which I see the IP of machine which is working as Reverse Proxy server for all such requests.What mistake did I do above.

I want to backup some data on my Fedora box to a external Hard Disk (USB). I mounted the external HD on my box. I wrote a bash script to do that and I scheduled a cronjob to execute the script. When I am online the script executes as planned. However when I am logged out the copy does not work. I also tested this with a cifs mount (via fstab) and that does not work either. I set the script to generate some output at the end and that is OK so the script does run when I am offline. I suppose the mounted locations are not reachable while logged out, is that correct? Is there a workaround so I can reach the mounted locations while logged out?

I have a Dell PowerEdge 2850 running Ubuntu 10.04 Server with SSH and Samba. My problem is that I am unable to execute my adduser.sh script which reads from a text file and adds users to the box and Samba. I have ran chmod a+x to make it executable and placed it in /usr/local/bin.
When I run sudo adduser.sh I get "sudo: unable to execute /usr/local/bin/adduser.sh: No such file or directory".
When I run adduser.sh I get "-bash: /usr/local/bin/adduser.sh: /bin/bash^M: bad interpreter: No such file or directory " I have been using Kubuntu as my home workstation for some time now but I have managed Windows servers but since I was given the freedom to setup this server I chose Linux.

Some time ago I installed LAMP in my server, but now I need to execute .php files from the command-line (in order to execute some manteinance scripts for mediawiki). Seems that the PHP files running in the server are run thru some kind of "module" in apache2. Can I tell apache2 to run a .php file in command-line mode using that php module? Or should I install a fresh copy of php-5? Won't that interfere with apache or mangle the system?

started setting up my 3rd ubuntu server under the OS of Ubuntu Linux 9.04 64 bit. I have configured the server to allow root access and am using this to execute this file. As you can see from the screenshot of PuTTy, the file exists but is refusing to load up. I am also able to nano the file. I have tried moving the file to /root/ and still had no luck.

I'm trying to install phpMyAdmin on my Ubuntu 10.10 server. I type the following command (I don't use "sudo" because I'm logged in as root, I know its not safe):
Quote: apt-get install phpmyadmin and go through the installation. I allow the installation to configure the database, and I chose the correct server (Apache2), when it asks for passwords, I use the same password that I use for the rest of the server (i.e. it is the account password for root, sudo, and my account). Once the installation is complete, I try and access it from a computer on the same network. I type "http://***.***.*.*/phpmyadmin" and I get the message saying the directory isn't there. I go into Webmin to confirm that the directory isn't there, and it isn't.
My questions are (1) Why isn't the phpmyadmin directory in my Apache Server root? (2) Is it installed with apt-get, if so, where? (3) How do I know what server I selected for it to install to? (4) What do I need to do to get it to install correctly?

I was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:
init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?

I've just installed subversion.I need to create a script /etc/init.d/svnserve that will start at boot time.I want to use start-stop-daemon --start so I can track my process and eventually kill it using start-stop-daemon --stop.My problem is that I can't get it to work and the documentation shows no exemple.
I've replaced $DAEMON by the whole line: svnserve -d -R -r $REPO_ROOT and got -d is not an option.I'm not quite sure what to do at that point. If someone has some experience with start-stop-daemon it would be great.

but I have a few Ubuntu server's that are Headless, and rather than walking to the server room with a display i thought, id rather push for a good challenge..So I would like to know how to remotely login to these Server's Desktop environments. not necessarily with more than one user at a time. just need to login to the machine's via VNC or RDC preferably VNC I do my admin work with Apple Remote Desktop. but I have RDC as well..
I set these systems up for my IT Department... and I need them to be super easy to access for the rest of my team. ( I am the only one aside from or Director privy to using the command line ) so in order to make it possible for normal humansI'm installing the desktop enjoyment on each of them now. but..From what I have found in my previous Linux adventures - it is not possible to VNC to system that is not already logged in, in other words if the machine is booted, but at the login window.. I have never been able to connect via VNC, I am only able to do this once the machine is physically logged in to it's desktop nvironment once that has happened I am able to connect with VNC, but,, something tells me this is possible - this is something I do on a regular basis with my OSX server's - and with RDC to manage my active directory server

I am installing VMware-server-2.0.2-203138.i386 on FC 12
Have an error when executing vmware-config.pl initially. When I try again it has the message:-
start of messages;
The following VMware kernel modules have been found on your system that were not installed by the VMware Installer. Please remove them then run this installer again.
vmmemctl
vmci
vmxnet
vmhgfs
vmblock
I.e. - 'rm /lib/modules/2.6.31.12-174.2.3.fc12.i686/misc/<ModuleName>.{o,ko}'
Execution aborted.
End of message
I tried remove them using modprobe e.g.
modprobe -r -v vmemctl the response was "WARNING: All config files need .conf: /etc/modprobe.d/anaconda, it will be ignored in a future release."
Subsequently I tried vmware-config.pl, but have the same error.

I have a web server in my kitchen with apache running on it. Since the upload speed is quite low due to my isp I would like to execute a bash script that uploads a file to another server through a website (which is htaccess protected) The idea in general: Someone with access to my website browses through a folder, copies a file path to an input form and presses "upload". Rather than executing a bash script directly I could have a cron job running in background that finds the path and then uploads the file to the other server I have userspace on and is accessible via sftp/ssh. The file would be than erased later after a couple of days or so. That person would be able to access the file with higher speed some time later without logging in via ssh and doing all that manually.

I am running ubuntu 10.04 as a web/file server. I have set up several cron jobs in the past which until recently were executing normally. However, a few days ago, cron jobs stopped executing after a restart. I was able to fix the problem by deleting and reentering the cron jobs, but only until the next restart. ps -ef lists cron.
Summary:
1.) Cron was working --jobs executed without error and restarts worked fine
2.) Cron jobs stopped executing after a restart about a week ago --ps -e still lists cron
3.) Removing all cron jobs and reentering them by copying and pasting fixes until next restart
4.) Cron job syntax is known to be correct since they were executing before this problem arose.

I am bit lost with configuring my apache2 web server. From the book I am using it says for me to configure apache2 to support PHP I need to execute "./configure --prefix=/usr/local/apache2 --enable-so". From what I can determine Apache2 is located in "/etc/init.d/apache2" folder. I used a Ubuntu 9.04 distro (I386 Server Ed.) to install the server. I added "Kubuntu-desktop" for viewing. Then performed web upgrade to Karmic 9.10. All went well !! Question is; Where do I execute a command to enable PHP support? Once again, the command is to look something like "./configure --prefix=/usr/local/apache2 --enable-so"

I am quite new to this ubuntu business, but i like what I'm seeing so far. Well, almost everything that I'm seeing. I seem to have run into a tricky problem with xubuntu 10.04. I was in the process of customizing my desktop appearance (via Xfce4 Settings manager), and I found a nice theme to go with (dusk I think it was called). I then went on to change the window settings and starting from the bottom most option I browsed the various styles. After a few of these my computer decided to log me out quite suddenly, and I was prompted to login.
This is where the problem is: I type in my password and it logs me in for maybe a half a second only to log me out again. No matter how many times I put in the password I keep getting logged out. So now I'm running xubuntu 10.04 off a pendrive that was used in its initial installation. Is there any way to log back in and stay logged in long enough to undo the window styling at fault? I had put in quite a bit of work migrating files, installing all sorts of things and setting up fancy launchers, and I would prefer not to have to redo it again.

I just recently made a new user so that other people cane my computer when I'm not around, and I have noticed things aren't working right. For example,rted a few files downloading in Firefox and then clicked 'Switch from Fracta', expecting it to be like windows and the downloads would continue in the background while people log into the other account. But the screen just went black. Completely unresponsive.ouldn't let me ctrl-alt-f1 to the command line and alt-sysrq-R,S,E,I,U,B didn't shutdown and restart the pc. Also, It is not uncommon for the computer to freeze when my screensaver starts after however long of inactivity and the computer doesn't respond at all

Whenever I want to shut down, I have to enter my password, because shutting down while other users are logged in is a privileged operation. Now, I couldn't download an update because the update lock was in use. I'd be surprised if someone had targeted my system, especially because I didn't install any obscure .debs or anything recently, but I'd really like to find out if it's been compromised somehow. Say, by obtaining an overview of all users currently logged into my system or something. Is that possible?
