To protect your server against rootkits, backdoors and other security problems it is recommended to install and use Rkhunter on your <a title=\"Linux VPS\" href=\"https:\/\/www.rosehosting.com\" target=\"_blank\" rel=\"noopener noreferrer\">Linux VPS<\/a>. Rkhunter (Rootkit Hunter) is a very useful open source software utility that makes various checks on the local system and scans for known rootkits, local exploits, malware and backdoors. Rkhunter checks to see whether the binary files or system startup files have been modified, and performs various checks on the network interfaces, including checks for listening services and applications. Rkhunter runs on most Linux and UNIX systems. It can be run from the command line, but it can also be scheduled to execute on a daily basis as a cron job.<\/p>\n<p><!--more--><\/p>\n<p>To install the latest version of Rkhunter on your server, execute the following commands:<\/p>\n<pre class=\"brush: bash; gutter: false\">wget http:\/\/downloads.sourceforge.net\/project\/rkhunter\/rkhunter\/1.4.0\/rkhunter-1.4.0.tar.gz\r\ntar xzfv rkhunter-1.4.0.tar.gz\r\ncd rkhunter-1.4.0\r\n.\/installer.sh --install --layout default\r\nrkhunter --update\r\nrkhunter --propupd<\/pre>\n<p>Use the following command to perform a test scan on the local system:<\/p>\n<pre class=\"brush: bash; gutter: false\">rkhunter -c<\/pre>\n<p>Set up a daily cron job on your <a title=\"Linux VPS\" href=\"https:\/\/www.rosehosting.com\" target=\"_blank\" rel=\"noopener noreferrer\">Linux VPS<\/a>:<\/p>\n<pre class=\"brush: bash; gutter: false\">vi \/etc\/cron.daily\/rkhunter-cron.sh<\/pre>\n<pre class=\"brush: bash; gutter: false\">#!\/bin\/sh\r\n (\r\n rkhunter --versioncheck\r\n rkhunter --update\r\n rkhunter -c --cronjob \r\n ) | mail -s 'rkhunter Daily Check' your_email@address.com<\/pre>\n<p>Do not forget to replace &#8216;your_email@address.com&#8217; with your email address.<\/p>\n<p>Execute the following command\u00a0to make the script executable:<\/p>\n<pre class=\"brush: bash; gutter: false\">chmod +x \/etc\/cron.daily\/rkhunter-cron.sh<\/pre>\n<p>That&#8217;s it!
