Changing Timezone in Wireshark

Hi

I don't think there is an outright method in wireshark to do it.  However you can set you TZ to some other value as described in this link  http://seclists.org/wireshark/2011/Oct/402


Get the list of TZ from here http://en.wikipedia.org/wiki/List_of_tz_database_time_zones


Now start wireshark like so to start displaying Time in EST.  Note this works in GNU/Linux OS.  Not sure about other OS.

$ TZ='America/New_York' wireshark &

Ubuntu not discovering other OS on my friends computer

I got burned by Ubuntu not discovering other OS on my friends computer.  I found the answer in the link shown below.


http://askubuntu.com/questions/11916/how-to-restore-windows-xp-menu-entry-in-grub




All we need to do is include the following five lines under /boot/grub/grub.cfg #40 custom OS detections......





As always try to take backup before you screw up something real bad.

menuentry "Some Operating System (on /dev/sda1)" {
    insmod ntfs
    set root='(hd0,1)'
    chainloader +1
}

http://www.cgsecurity.org/wiki/PhotoRec

Starting with GIT


Initializing giti init To initialize a Git repository
Checking the Status git status git status command to see what the current state of our project is
Adding git status
Git add octocat.txt
To check and add a file to git tracking mechanism.
Committing git commit -m “Add cute octocat story”
Adding All Changes git add '*.txt' Adding all *.txt files alone
Committing all git commit -m “Add all the octocat files” Now committing them.
History git log
Remote Repositories git remote add origin https://github.com/try-git/try_git.git To push the changes of local repo to the server
Pushing Remotely git push -u origin master The -u is to remember origin and master, next time we can just do git push
Pulling Remotely git pull origin master
Difference git diff HEAD
Difference git add octocat/octodot.txt
Staged Difference git diff –staged
Resetting the Stage git reset ocotfamily/octodog.txt

git checkout – octodog.txt
Branching Out git branch clean_up

git checkout clean_up
Removing All The Things git rm '*.txt'

Snort alert count on Google Earth

Requirement

For a long time I wanted to know how could I plot the alerts which each snort sensor is generating on a Google Earth based on geographic location.  If this could be done I could see from which location on the globe am I getting lots of alerts from.

Solution

The solution to my problem was all in the power of KML file.


Pre-requisites

1. Have snort running on many places.
2. Have barnyard to log your alerts (Optional if you are using old version of snort).
3. The last three characters of your sensors should be named after the airport code. (For example: Chennai sensor name "SensorMAA").  If you are wondering how to get all airport codes stick around.
4. View the snort generated alerts using BASE (Since my mysql query will work only on the BASE generated mysql schema).
5. Be able to run my bash script on the server which runs your mysql server.
6. Of-course Google Earth.

Making

Follow along there are a few steps.

1. Download the script and the support files as a zip from here.  The flow chart for creating the script is here.
2. Edit the file "GoogleEarth/Project/conf/mysql.cnf" to contain your IDS mysql credentials.
3. Run the file "GoogleEarth/Project/bash.sh" like ./bash.sh
4. Now Open the file "GoogleEarth/Project/Alerts.kml"
5. You could add bash.sh to a cron job which runs every 5 minutes so that the bar height on Google Earth would get updated automatically.



If you think I am forgetting something you bet your correct, you can get all the airport codes from the file you downloaded. "GoogleEarth/Project/resource/airport_codes.csv"
