I am a complete newbie to linux. I am currently taking a course at Devry university called netw240. I am in my 2nd week of class and am required to turn in a paper at the end of the coures were I write an automated shell script. I am currently using Fedora 12 on a Vmware player and want to try to write a script that automates the process of Logging user login activity to detect unauthorized remote access attempts.I am looking for pointers on were to start, examples, ect.. anything that can get me started. Also, is this type of script to much for a beginner?
I recently set up an automated shell script (bash on Ubuntu 8.10) to download new files from a server using ftp. Unfortunately the other end of the link is not terribly stable (and there is nothing I can do about this) which has resulted in the script hanging sometimes and then being kicked off again at the time set in the crontab.
This has resulted in multiple hung sessions taking up all the system resources.
The offending section of code is given below.
Code:
I'd like to know if there is a way I can force an exit if the connection hangs or alternatively if something like the Perl Net::FTP can handle these sorts of errors internally.
I am trying to use autoexpect and can't seem to get it working. I installed expect and expect-dev and have the autoexpect example files but when I try the % autoexpect command from the terminal all I get is;"bash: fg: %: no such job" - what do I need to do so I can get this to work? I am trying to create a script for an automated SFTP connection. I created a bash script that works okay but it gets stuck at the password prompt and I heard that autoexpect would be the best way around that
I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code: if [ $# -eq 0 ] ; then d=`pwd` for i in * ; do if test -d $d/$i ; then echo "$i:" code....
how can I create a shell script for ssh where I don't have to type the password manually?I have learned expect command and I have tried multiple examples, but it didn't work.
I am using Linux on my system. I don't have gui for my system, only console is there.
I have some task to create a menu box window using dialog in shell scripting.
I have to take input from user & save it in a file.
But this should like html form as e.g.
Name - ..................... email id - .................. phone - ...................... location - ...................
Submit Cancel
Such window should be displayed on console using dialog & then user will enter his information there as Name,email id, phone,etc & submit it, then it gets saved to a file. Here submit & cancle are buttons. I have to do it in bash shell scripting. Or give me some examples like the above with shell script code.
I was trying to create a shell script which will automatically login to the server 192.168.1.7 and checks if a user exists there or not, if it doesn't exist then it should create the user.I have very little idea about shell scriptThis is what I tried:Quote:
#!/bin/bash pass="sacharje" ssh 192.168.1.7
Now, how to pass that password automatically to the ssh when it asks for the password? (I can't use public key authentication here)
An external service I dont manage pushes mediafiles into a shared directory on my server. I need to move these files into their correct directories automatically. The problem is that if I run my script as a cronjob once every 3 minutes, I notice that the script copies files which are still on their way into my server. So I need to figure out how to have the script check that the files are complete (done downloading) before the script moves the files. This is what I got so far:
Code:
#!/bin/sh # Script by proximity 280709. # Locate correct directory
I am making some scripts to automaticly install linux-software.gcc,kernel,binutils, etc.) I have made a command to extract the packages, but how can I check if I can re-use my already extracted source-archives?
So I have a script that is supposed to check to see if a mail server is up and responsive. What I want to know is how I can send it the telnet escape character. I've tried:VAR=`(sleep 5;echo quit) | (telnet mailserver.timbuktu.net 25 2>&- )`
This works BUT there is a problem as the mail server may have been accidentally firewalled off. If this happens, my automated checking script will hang. What I want to do is send the escape character so that the '>' prompt comes up. They I should be able to send it "quit" even if it is hung on not getting a response from the server. VAR=`(sleep 5;echo -e '^]';sleep 1;echo quit) | (telnet arhqmg01.usarec.army.mil 25 2>&- )`
The above doesn't work. telnet interprets CTRL+] as '^]' but you can't type '^]' and get the same effect. So I guess what I need is to send the actual keystrokes. Like echo "somenumber" ; echo quit
I am using Kde 4.5 in Debian and I get some notifications after start that I need to update something. How can I disable it (I often don't want to waste bandwidth for such things)? I am using Debian Wheezy and Kde 4.5
While I have been using Linux for many years (Slackware), I have found myself facing a special need that I can't quite figure out.I work at a club where I use iMovie on my Mac to create a DVD that plays on all of our TV's displaying our upcoming lineup of bands.In order to save on DVD's, I would like to create a very small form factor PC running Linux with the following requirements: the computer must boot into Linux and log itself in, the computer will boot up with a thumb drive attached containing a movie file of the most Linux compatible video format. After booting up and logging itself in, the video on the thumb drive must start playing automatically in full screen mode and in a continuos loop.So the whole thing needs to be automated from boot to playing movie; only the power button should ever need to be touched.
I am learning PHP to take information submitted in a web-form and store it in a MySQL database, but I also need it to automatically print to the laser printer I have setup. So that a notice or printout is produced of the information.
My question is... what route do I go to automate printing from web-based information in a PHP/MySQL database?
Is it PERL ? or does PHP have a feature to do this?
I want an automated install (via CD or USB) of Ubuntu 10.04 ...on 100 remote machines located all over the country, using a Kickstart configuration file accessible from my web server.
How do I create the boot CD (or USB)?
How do I specifically add the boot parameters to that boot CD (or USB) to tell it the URL to use for it's automated Kickstart install?
This is my first post and I am a linux newbie.. took on the challenge of setting up an ubuntu server with proxy and firewall with vpn access as well.. sounds good? While messing with things, I installed ebox server, know called Zentyal and perform backups, however, when performing a full restore, following instructions and all it does not restore correctly. I ran many attempts with verious configurations and still allways got some errors, such as eboc-ebackup failing to start, etc. most noteably wa sthe ldap error, which i figured out how to fix by restarting once logged into and then rebooting.
I say the Clonezilla options for a full backup, and it sounds great, but does require me to perform a full abckup, while bring the server down to perform. What I wanted to know, was what do you recommend for performing a full backup (possibly to NTFS partition or USB key with FAT32) with automation or even if i had to perform the trigger, just without needing to bring the server down, so when i go into production i dont have any issues backing up anytime?
Some time ago I read a discussion in /r/linux and someone mentioned a script that checks new messages in IRC channel (in irssi client) and if they contain announce urls for torrents, they are passed to a torrent client (rtorrent) for downloading. Sadly, I didn't bookmark it, nor I could find it now. Maybe someone has a similar script?
I'm using Ubuntu 11.04. I'm searching for an automated way of installing the latest version of Flash for Firefox. We are using our machine as a testing server and it would be nice to be assured we always have the latest version of Flash instead of having to manually update it whenever Adobe comes out with an incremental update.
I just finished set up a PXE server, and was wondering is it possible to automated save/redirect files from the client into server? Basically, test will be running on client, and wanted to save the result(text file) into server after done testing.
I decided to try and find a home inventory application. I found one called "Attic Manager" that works in Ubuntu. [URL]
The instructions are to run it from the terminal. That's ok for once and a while, but a pain if used regularly. So I tried to set up a launcher for it. I couldn't seem to get it to work. In the command, I simply put in the path and file name, but can't seem to get it to work.
I would like to create some aliases for bash shell. On other Unix/Linux machines I have done this using the alias command like this: alias rm rm -i
When I type that into a terminal on Ubuntu, it looks like alias is not installed. I get this:
bash: alias: rm: not found bash: alias: rm: not found bash: alias: -i: not found
I tried adding the alias to .bashrc instead, but then I get the same error message every time I start terminal. Just for fun I tried apt-get install alias, just to see what would happen, and it installed something called libperl-alias instead, and alias still doesn't work.
I tried to create logfile for the below shell program but i was not able to get log file,can anyone help me for the below program to create a log file for the shellscript.
How do I create a user account in a shell script? I know this may sound n00bish to you, but I know it's more than just mkdir-ing the home directory and subdirectories.
I came across this script a while back that i found. What i want to do is edit the script to create a default web page in /var/www/html a new user is added through the script.What the script does now is adds a user and sets a password for the user. What possible way (either through a combination of python or c or some other language) could i add to the shell script to do this? I've tried just dointhe command to touch index.html /var/www/html but it puts it on the desktop. Here's the script....
Code: #!/bin/bash # Script to add a user to Linux system
I was planning on using my VPS to grant some of my friends shells. The problem though is that I don't want them doing crazy stuff on it, like using up all my RAM or disk space. I would like to limit them to a very small 25 mb disk space, and allow them only certain application in /usr/bin like python perl irssi screen etc. I do NOT want them to be able to cd out of their home directory. I really want this to be setup like the shell provider SHellium. I can setup the FTP and SSH stuff myself.
I have Disk /dev/cciss/c0d1: 599.9 GB, unallocated on CentOS release 5.4 .
I need to create about 30-40 LVM's worth 500GB as raw devices for sybase . is there a way to script it or anyone already has it ?
The problem is that each time we need to do fdisk /dev/cciss/c0d1 and enter the partition no to create a new one .. how to overcome that problem and automate it in a script ?
