How to change the Notifications Email’s Subject in Plesk.

Last day one of client asked me about this and on checking I can see the pre defined notification email has edit option for the body but not for the Subject.

To get this done, we may need to access the plesk database and change the Subject of the desired notification from “psa.notification” table

Before you start working on this, always take a mysqldump for “psa” so that if any thing goes wrong, you can simply restore from the backup.

ntPHPSelector version 1.1.0 – released with reported bug fix

Last day we have received a complaint saying ntPHPSelector installation was failing on a specific server. Up on checking ( we don’t charge for our plugin support of course ), we could see that it due to an issue in the manage script that prevents it to sort versions on RHEL 5 based systems. We have corrected it and released the fix; it is available to download now. Please note that this doesn’t include any feature changes; no users have to use the new script and re-install it if ntPHPSelector is already running fine on your servers.

Thank you very much for using ntPHPSelector. Please send your feedback to info[at]nixtree.com.

How to stop other domain name point to your IP?

I could see that some domains point their host to my IP. For example, if someone type www.other-domain.net, it redirect to my IP: 255.255.255.255 which is address of my web. Since my domain is hosted on a dedicated IP, the domain www.other-domain.net  will load the content of my site.

There is absolutely nothing you can do about people pointing their DNS at your IP address because it is their DNS. One thing they can do is direct people to your website with their domain name in the URL bar. You can easily redirect visitors to the correct domain by putting this in your .htaccess file.

RewriteCond %{HTTP_HOST} !^www.my-domain.com$
RewriteRule ^/?(.*) http://www.my-domain.com/$1 [QSA,R=301,L]

Also try reporting domain registered companies for abuse.
