I'm trying to access a login page that runs xbap.
[URL]
Doesn't seem to work in Ubuntu - it just downloads the file instead of taking me to a login page. It's not a browser problem as I have the latest version of Firefox, which works fine under Windows XP.

I have just a one line script that runs telnet, and even thoughI've looked around I thought maybe someone could just tell me if there is a way to automatically login to the telnet server without having to type it in everytime. It's more of a hassle type of thing, but no matter what I've tried, I can't get anything to work.

I'm a newbie on Linux and currently in the process of installing it. I'm planning to install the latest version of Apache, MySql, and PHP on the machine with a debugger on it. I haven't decided which debugger is suitable for this environment since I don't have any experience on it.

I hope someone can help me with this. I need to call the same thread multiple times, but only run one thread at a time. So what I do is create the thread which runs then drops out. Run the main loop and after some time pthread_create the same thread again. So in pseudo code
[Code]...
I always presumed if I run a thread and it reaches with a pthread_exit, then the thread was destroyed? However I've found that after I've created the thread several 100 times the programme crashes? So can anyone advise how I call the same thread over and over?

I need to write a shell script that will be run from cron every minute or so. The script will use rsync to keep some folders across several machines in sync. I am very new to shell scripting so some answers might seem obvious but they are not to me:
1. How do I check at the beginning of the script if the script is already running and abort if it is? I saw that most processes use a PID file for that but I am not sure this is the right case for that and in fact how to do it exactly
2. Assuming the list of target machines/dirs to sync are supposed to come from some config file. How should I code that? Just use the normal shell tools that I already know (cut etc) or is there a better way?

I'm trying to do a shell script which are suppose to run a program as a specific user at system boot up. The problem is that I don't know for sure how to make the script add the users password to the prompt when it's necessary.
Basically the program would be run like this:
sudo -u extrema program_name -r /srv/program_name -d
and in this example the password is, "hidden".
How would I make this script run this program as user extrema with the password "hidden" at boot-up? I know how to put the script in the rc.X directory and so on, its more the syntax of the code.

I've browsed the internet, but haven't found a satisfying answer. Hope this forum can help me in the right direction.I'm exploring the possibilities of creating a program that manipulates (writes to) two different video cards.I program in C and hope to avoid high level libraries like Xlib to keep the mem footprint as low and the performance as high as possible. Windowing is not important no desktop environment will be used. Be able to write two pixels (one to each screen) to would do.
How would I go about?To give an idea of the solution I'm looking for:One screen will show thumbnails of images on the hard drive. Clicking an thumbnail on display A will show the selection full screen on display B. On a laptop; preferably thumbnails on the laptop screen and the selected image on the external monitor.Is this possible with just low-level libs or do I need X or some third-party software to make life easy?

For a while now, every time that I log back into my desktop from hard start or from restarting the X server, I get these 3 terminal konsole windows that are open on my first desktop environment. It's seems as though whatever work I was doing when I had those 3 konsole windows open got saved somewhere and is reopening them every time I get back onto the desktop. I've tried to locate the problem by looking in .bash_profile and .bashrc but to no avail. If anyone has a solution to this, that would be awesome.

When ever I log on to Ubuntu 10.10 I have to enter my password twice (three times if there's a time lag and the screensaver kicks in). This is very annoying, I didn't need to do that with previous versions

I have a small problem regarding multiple X sessions. I want 2 X sessions started automatically on boot with 2 different users auto logged in and 2 different sessions running.
On first X session I would like to have gnome running with user1
On second X session I would like to have xbmc running with user2
So far my computer logs user1 in to a gnome session via gdm on boot. But then I have to launch a tty, log in as user2 and then start xbmc in a new X session.
How to make it work? I would also love to have the second X session active after boot. I am running Ubuntu 10.04.

I am running a ubuntu server 10.10 with SSH, and OpenVPN. I use it mainly for the VPN, but I have seen log in attempts such as:
Mar 22 14:52:53 UbuntuSvr sshd[2397]: Invalid user support from 85.217.190.69
Mar 22 14:52:55 UbuntuSvr sshd[2399]: Invalid user student from 85.217.190.69
Mar 22 14:52:57 UbuntuSvr sshd[2401]: Invalid user transfer from 85.217.190.69
Mar 22 14:52:59 UbuntuSvr sshd[2403]: Invalid user user from 85.217.190.69
[Code]...
Is it possible to make it so when some one has tried logging in 5 times with an invalid user/pass that the ip is banned for 10 minutes? I have password auth set to no and am using keys.

i'm trying to set up password-less SSH login between multiple instances on my server. My goal is to be able to monitor all instances, whether I created them or not, with Zenoss.
Current setup: 3 machines
A: Zenoss host- owned by me, Access via putty with my keypair
B: instance- owned by me, access via putty with my keypair
C: instance- owned by teammate, access via putty with their keypair
I'm able to set up password-less SSH login between the instances I have created (A to B), however, I cannot between my Zenoss monitoring instance and any instances not created by me(A to C). Whenever I try to copy the id_rsa.pub file to these instances, I keep getting a Permission denied(public key) error. I believe the problem is that I have log in to my instances using my keypair but must use the the other instances creator's keypair to access their instances.

I know that in previous versions of OpenSuSE one could be in front of the screen/KBD/mouse get things started, and log into another session and get things started there and run some apps, and so on. Now with OpenSuSE 11.x I see no means in which to do so. Is there another way? Point being is that I want to run one application as one user session and another application in yet another user session. Either one I can get to by switching user accounts at one screen/kbd/mouse. Or through VNC. No need to run something like xen or VMWare and incur additional overhead. (It is next on my list to try though.

I have a computer with three video cards and six monitors. Works great on Windows. Trying to get it to run Ubuntu 10.4 as well. It loads fine when I have it configured to run on one adapter; detects both screens, runs ok. But I want to turn the other 4 monitors on and run the whole thing as one extended desktop (one session, etc). So I downloaded and installed the newest ATI driver for Linux, which seems to work, kinda. I ran this to set up the screens:
aticonfig --adapter=all --initial -f Now when I boot, Ubuntu seems to turn on all the screens (3 viewports, each with two cloned displays from what I can tell). When I enter my login info OR move the mouse off the main screen, the screens freeze and the kbd/ms become unresponsive.

I googled a lot but I didn't find anything about this. I have multiple accounts on the same ftp server (the server is not mine I don't access its configuration)
If I write ftp://hostname on the location bar it lets me login, but only allow me to be in only one account at a time. Putting ftp://hostname on the location again just opens the account I logged into and I'm unable to login to the other account to move files between them conveniently.
Is it possible to log into multiple accounts on the same server?

It's been awhile since I've been on here. I suppose that can be considered a good thing, since I made the completely transfer to Ubuntu three months ago and everything's been running completely smoothly. Anyway, security is a pretty big thing to me. I usually change the root password, take sudo off (and default gksu, not gksudo), encrypt my hard drives, etc... One thing I also do is create a separate password for my login keyring. I don't mind having to enter one extra password at login, but it started prompting two times, and now three. It's the same password every time, so my question is..

I use a mencoder line to convert .avi to .mpg (dvd player compatible), it works well but i can only do one file at the time. It requires giving the input and output directories and the files name. I tried using (*.avi *.mpg in the command) on the directory but it just add up all the .avi and convert them into one huge .mpg. My goal is to have a script that would convert all the .avi files from a directory to the same amount of .mpg and also keep the naming of those files. Here is what i work with on single files:
Code:
mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,harddup
-srate 48000 -af lavcresample=48000
-lavcopts
