I have created a script which asks the user a few questions and then it configures the wireless network. I'd like to run it somehow while Ubuntu still boots by pressing a key for example. Let's say, while booting, when it comes to the script I made, it will sleep for a few seconds giving the user the oportunity to press the pre-defined key (eg: spacebar). Once pressed, then the script will load.

I have to execute certain commands (like shutdown Tomcat) on several servers so I'm using a loop and ssh. I put the server's IP on a CSV file which I parse, execute the commands for each line and send the output to a file. The problem is that after processing one line the program stops execution. I wonder if someone could lend me a hand with this, I'm new in bash scripting and I ran out of ideas.
The CSV (servers.csv) file looks like this:
Code:
192.168.254.5:Server 1
192.168.254.6:Server 2
...
And the script looks like this:
Code:
#!/bin/bash
while IFS=: read ip name
do
sshpass -p "pass" ssh -o "StrictHostKeyChecking no" root@"$ip" 'sh <CATALINA_BASE>/bin/shutdown.sh' >> output.log
done < servers.csv
I have a file server running Ubuntu 9.04, with 2 1Tb Drives. I did a normal shutdown, and when I attempted to start the server again, it returns an error of Drive error. Then I must press F1 to resume. If I disconnect the 2nd Hard disk it will boot normally after pressing F1. If I leave the Disk connected it just hangs up after pressing F1. I can run it with 1 disk, but I cannot run it headless if I have to press F1 to start it every time.

View 6 Replies View RelatedI am working as system administrator for the past 5 years, but only on Windows XP systems, I recently moved to Linux, frankly speaking a few days ago, and i got many problems with it. may be as i am a beginner. My Problem started with Ubuntu 9.04 amd 64 and now with 10.04 beta.
The main problem I installed the wine (I am aware that wine is not compatible with all softwares of microsoft) and Installed microsoft office 2007 and it installed successfully but after installation when I launched Microsoft Excel it got hanged (only the Microsoft excel) and loading logo stood on top of all applications, then I decided to restart and pressed the restart button from menu on the right top. but there was no further response, then I pressed the reset button after waiting for 3-4 minutes to get rid of that logo of Microsoft in the center of my screen.
Now, when the Ubuntu was booting, Text arrives and disappears fast saying dev/file system has errors the logo of Ubuntu 10.04 and dots of loading at the bottom arrived and text written in the bottom of that "on of the drives needs to be checked, please wait it may take some time" Press 'C' to cancel disk check up. Now, its checking for a long time maybe for 30 minutes and the bottom text disappears and the loading Ubuntu 10.04 logo still remains and nothing happening after that.
I Pressed alt+crtl+del 2 times, it restarts saying that saving some alsa process, then again the same thing after restart. If I press C, it displays in the bottom of Ubuntu 10.04 logo "/File system has errors" and the loading screen remains like that. Now what is the solution and what are the precautions to be taken while using Ubuntu, as I was interested in introducing Ubuntu to marketing managers of offices, who wonder on the Internet all the time finding stuff and getting attacked by viruses. If this type of problems continue in Ubuntu, it will not be safer to use it, as if it wont boot during sudden power failures, that could result in a big problem.
I am running usb version of lucid 10.04.2, with many apt-get installs. Shortly after running awhile, programs will not run, I get either an "input/output error" or "Bus error (core dumped)". (Examples of programs rendered inoperable are top, df, file)
I've read something about a memory leak in Lucid, but in my case, the computer doesnt slow down, things just stop working. Is this a known problem with Lucid? I'm thinking maybe one of my apt-get installs corrupted something. Is this a known problem that has a software update available?
Here is the output of "top" which fortunately currently DOES work, while other progs don't. (the memory usage stays constantly in that 1.5 GB range)

My main problem right now is doing floating point arithmetic within a bash script, with variables.Right now I have a folder called "myExamples" with a script called "run_example" that runs with no issues.I plan to(1) create many folders inside [myExamples], that are named [example10] [example11]...each containing an identical copy of (run_example),(2) modify Line 172 of each copy of (run_example)...in one copy, it would be 3.00, the next copy would have 3.05, etc. (This part doesn't work!)How can I use the available calculator bc code to do floating point operationsMy code is below -
#!/bin/sh
# run from directory where this script is
cd `echo $0 | sed 's/(.*)/.*/1/'` # extract pathname
[code]....
Whenever I got to type the command below:
#iwconfig eth1 essid mynetwork key xxxxxxxx
#dhclient eth1
to use this command, i have to be in su or sudo. Is there a way I could allow all users to invoke these commands without the root password?? I try to make a file (wireless.sh), which consists the commands above, in /usr/local/bin/. Change the mode to 755 (chmod 755 wireless.sh) however, it does not allow me to use this also.

View 1 Replies View RelatedI have created a glade file which so far have two regions in it:
1) On the right division is a toggle button which calls a C script when enabled.
2) I have a drawing area, in which I would like to plot a point (X-Y scatter plot). The plot should be generated dynamically using a C script. I am not sure how the integration between the two is possible for a drawing area.
In glade what properties of drawing area should I set? eg.expose event, realize etc. I was thinking of using cairo for generating the plot.

I'm trying to do a little bit of setup on our new server and could use a hand.I'm working on creating a simple display script that our users can SSH in and invoke, here is what I'm attempting to do.
Requirements.
1. Must run X over ssh on Mac OS X 10.5 or greater
2. Must work in the office, or on the road
Implementation:
1. Set up the system to auth against LDAP (Open Directory)
2. Create a script on the PATH that checks which displays are available, and launches Xephyr for the first available one.
3. Create a client script that performs the SSH and Xephyr command so that users can simply click the script to start an X session.
I have 1 set up, but I'm having issues with 2 and hence 3. For instance, I can start XNest with the following commands.Start my SSH session
ssh ninet@10.0.1.50 -X
Load XNest
Xnest :1 -ac -geometry 1024x768 -once -query localhost

View 1 Replies View RelatedMy computer is connected to the college lan where almost all machines are some variant of Windows OS. If i use Places > Network, while windows network is displayed, mostly it returns unable to mount shares, my workaround for this problem is I use some tool like nbtscan to see which hosts are up and then use network > Connect to Server > windows share and type in the ip address, this mounts the windows share even though Places> network doesn't display such hosts. My question is there some command line way where I can invoke nautilus to mount the windows share, ie the same job connect to server > windows share does? And is there some application like say lan surfer for windows which lists all the folders shared by a windows client.
View 3 Replies View RelatedI have a very strange problem. My computer is unable to boot from any hard disk but is able to boot from any CD or DVD. I have double-checked the BIOS settings and I am unable to figure out why is this happening. I have noticed that the Windows installer boots from the CD only if one presses a key when the message "Pressany key to boot from CD..." is displayed on the screen, otherwise it boots from the first hard disk.I have a triple boot system with Windows 7 (64-bit), Ubuntu 10.10 (64-bit), and Fedora 14 (64-bit). I have a dedicated GRUB2 partion on one of my disks. What I want is a boot-loader (any would do) on a CD/DVD/USB drive to chain load the GRUB2 present on my hard disk, without a delay, that is, without showing any message, menu, warning, etc. So, is there a way to do that?

A problem on first asus eee's is the keyboard: also just typed a letter once, the laptop writes it double (every 200 letters more or less). For example it looks like this while writing: "thiss is a ttest" For Windows XP I found a way to fix it: i increased the time, that limits writing letters twice by fast typing. Its not the time "Repeat Keys" Delay (Keyboard Settings "Key presses repeat when key is held down")! In fakt its the opposite: It limits pressing the key to fast.
