 <\/p>\n

Basically i am a tech-enthusiastic.<\/p>\n

When we seek for any support, Linux admins used to connect and work remotely on our servers which are hosted in a remote location.<\/p>\n

I was so interested to know how they fix the issues , So i came up with this idea of getting the history of terminal commands they typed in to terminal into my mailbox automatically.<\/p>\n

I tried this small script and it worked well.<\/p>\n

I first created a script which will send a mail with the history contents.<\/p>\n

#cd \/tmp<\/span><\/em><\/p>\n

#vi hist.sh<\/span><\/em><\/p>\n

and typed the below lines.<\/p>\n

#!\/bin\/bash
\nNOW=$(date)
\nmail -s “Log $HOSTNAME @ $NOW” balusreekanth@gmail.com <$HOME\/.bash_history<\/em><\/span><\/p>\n

entered !wq<\/span><\/em> to save and quit from vi editor and to make it executable<\/p>\n

#<\/span>chmod -x hist.sh<\/span><\/p>\n

Now the script is ready to send email with the bash history.<\/p>\n

We can test it by executing the script #.\/hist.sh<\/span><\/em><\/p>\n

Now We can add the script to crontab and schedule it to send email periodically .<\/p>\n

I wanted make it to send the command history automatically whenever\u00a0 the .history file is modified whichmeans ,<\/p>\n

whenever someone connected to terminal ,I should receive an mail with a copy of the terminal commands history.<\/p>\n

To achive this I used incrontab . Incrontab is just like cron scheduler , but with additional capabilities<\/p>\n

-which allows us to configure like file ,directory watch etc.,.<\/p>\n

 <\/p>\n

I downloaded incron rpm from http:\/\/pkgs.repoforge.org\/incron\/_buildlogs\/<\/a> and<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

After adding root user to \/etc\/incron.allow<\/span><\/em> , I typed incrontab -l<\/em><\/span>\u00a0 which returnded “no table for root’<\/span>\u00a0 ,because I dont have any jobs configured yet.<\/p>\n

I typed #incrontab -e<\/em><\/span> to create a user table and added this line ~\/.bash_history IN_MODIFY \/tmp\/.\/hist.sh<\/em><\/span><\/p>\n

( assuming we have the script file in temp directory) .<\/p>\n

 <\/p>\n

Voila thats all ! I just received an email<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n
