از دوستان کسی هست برای حل 4 مشکل امنیتی زیر کمک کنه:
Check /tmp is mounted as a filesystem -> /tmp should be mounted as a separate filesystem with the noexec,nosuid options set
Check /var/tmp is mounted as a filesystem -> /var/tmp should either be symlinked to /tmp or mounted as a filesystem
Check VPS FTP PASV hole -> Since the Virtuozzo VPS iptables ip_conntrack_ftp kernel module is currently broken you have to open a PASV port hole in iptables for incoming FTP connections to work correctly. See the csf readme.txt under 'A note about FTP Connection Issues' on how to do this
Check nameservers -> At least one of the configured nameservers:
ns1.site.com
ns2.site.com
should be located in a topologically and geographically dispersed location on the Internet - See RFC 2182 (Section 3.1
