Root Login Alert!

Want to get notified as soon as someone access your root ssh account? This is the best way to do so.

NOTE: This process requires a linux server.

So lets get started!

1. Login to root SSH

2. cd /root

3. pico .bashrc

4. Scroll to the end of the file then add the following:
echo ‘ALERT! – Root Shell Access (YourserverName) on:’ `date` `who` | mail -s “Alert: Root Access from `who | cut -d”(” -f2 | cut -d”)” -f1`” you@yourdomain.com

Replace YourServerName with the handle for your actual server
Replace you@yourdomain.com with your actual email address

5. Crtl + X then Y

Now logout of SSH, close the connection and log back in! You should receive an email address of the root login alert a few minutes afterwards.

Have Fun

Change your hosting company without downtime

Most of the webmasters encounter issues with their host and at the last they need to move. There are too many problems like downtime, sql errors, blah, blah, blah while moving. I have written a small/simple tutorial on how to move your site to a new host without facing any problems.

As you know the first step will be backing up the data.

Secondly get the tools you will need for moving the site.

1) A good, fast and reliable FTP Client. (For ex: FileZilla, SmartFTP, CuteFTP, CoreFTP)

2) Get some details of your new host (IP, Hostname, Your Username and Password, FTP Port)

Don’t forget to inform the visitors that you are moving and the site may be un-available for some time.

Now, Download the files and SQL Database from your old host and upload to the new one. Don’t forget to change the sql details from the script which you use or you will start getting MY-SQL errors. Now, Get the temporary url of your site from your new host and check if your site is working fine or not. Then change the nameservers of your domain name from your domain control panel and take a deep breath.

Now your site will be moved to the new host without any downtime as soon as the DNS is resolved.

Have Fun…
