I was assigned to write a bash script in backtrack which will reveal the active IP Addresses on a /30 network. Normally I would not have a problem with this, but I just dont understand because would you not need the entire prefix (ex: 192.168.1) in order to ping sweep for a certain IP range?basically what I'm asking is...How do I nmap a list of IP's for a "/30 network" as that's all that we're given.
View 3 RepliesWhen you are performing time consuming operations in bash like installing new software, is it possible to write text that will appear at the prompt when the operation has finished.
E.g
Imagine running:
apt-get install eclipse-platform
Then it will use quite a while to finish while you see the installation log, meanwhile I want to create new folders (workspaces) which Eclipse later will use.
Is this possible without opening a new terminal (or tab)?
I am about to write my first shell script for backing up my server.
These are the steps I have identified so far.
Copy files to be backed up to /srv/backup/ run mysqldump and copy the file to srv/backup/databases run duplicity to backup /srv/backup/* to another folder on my machine
I am writing a bash shell scrip that will be run everyday, and will carry out the three tasks mentioned above.
Note: point 3 (backing up to a local folder) is only a temporary measure - to allow me to understand what I'm doing, since all the tools I am using, are new to me. Once I can backup and restore correctly, I will use duplicity to compress and encrypt the files and upload them offsite.
If my understanding of duplicity is correct (according to the documentation here), the first time I run the script, a FULL backup will be done. Every subsequent backup will then be incremental. I will then force a FULL back on say a weekend.
First things first though - I have a few questions:
I would like to use backup rotation for the 'scheme' described above - I would like some recommendations on what kind/type of rotation to use. Once I have implemented the backup rotation, how can I restore from a particular day back in time (assuming the backup exists of course). ?
I am running Ubuntu 10.0.4

I need to add a feature such that instead of hardcoding the ip address .. it takes them from a list and makes new files for each ip address for logging.. And also when log files are completed , They should be compressed using tar. How should i go about adding both these.. This is my first bash script.
I have for example the following IP addresses:
24.172.220.218
41.239.36.19
63.215.202.234
66.176.124.22
[code]....
How can I sort those IP addresses? I want to sort them using the first 3 numbers I also want to count the number of times that address is repeated This is a batch program.
I am new to linux and am trying to write a script that will ping IP addresses and say either online or unavailable.

I'm on a Dell Inspiron 6000. I installed i8kutils and it works. Fan speed reduces CPU temp from 50C to 44C. A start-up script invokes the i8k module: $ udo /usr/sbin/modprobe i8k force=1 which creates /proc/i8k. The man page for i8kctl is straightforward: a few simple commands to read info from the aforementioned file.So. I know nothing about writing even basic bash scripts. I gave it a go here but I know this is way wrong. Would anyone like to help a guy out? This is my starting point (don't laugh):

i am running backtrack3 with vmware station in window 7. but the problem is when i enter iwconfig it does not show my alpha awus036h. it does not detect my alpha card. if anybody can help me regarding the same???
i have already tried to set it in vmware station menu bar vm=>removable devices to get my wireless but it showing a usb device connected... not showing my wireless..
I have a Toshiba laptop with an Intel Pro Wireless 3945 wireless adapter. If I boot backtrack from a CD, the wireless card is found and I can run airsnort and collect packets. When I use vmaware to boot backtrack3, my wireless card is not found. My network connection is set to bridge in vmware. Does this have something to do with windows using the wireless adapter at the same time vmware is?

View 3 Replies View RelatedI have my email on a separate partition so that my email doesn't get destroyed when I do new linux installs (I have emails from 5 years ago now). I also keep my sylpheed email addressbooks. This partition is writable by anybody and I have also made my user the owner of this partition during each linux install (media/email). When I set up sylpheed I tell it that my email is in /media/email and then it is able to write incoming messages to that location. The problem I am having is that I make symbolic links for my addressbooks from ~/.sylpheed* to /media/email using this:cd ~/.sylpheed*rm addrbook-000001.xmlln -s /media/email/addrbook-000001.xml addrbook-000001.xmlSylpheed finds my addressbook ok on my email partition but changes that symbolic link to a file on ~ when it writes new addresses. What am I doing wrong...I want it to write new addresses to my email partition?
View 4 Replies View RelatedIn school, use SUSE Server and made it by DHCP but in my hand I changed many rules. All are OK at the start but now they requested that they who are principal, and vice principals are want to use the Internet without filtering.
So I've made new rules by using Webmin software to control the SUSE Server. 1st I've gave static IP from LAN x.x.x.40 to x.x.x.45. 2nd IP is x.x.x.12 to x.x.x.15.
At First, there's nothing happen but now I've got problems because Server gave DHCP so that Server gives IP itself and conflict with static IPs. And also I can't find in Webmin software how to disable the DHCP Assign.
