• Get application security done the right way! Detect, Protect, Monitor, Accelerate, and more…
  • I was playing around with testssl.sh and got this error.

    Fatal error: Neither "dig", "host", "drill" or "nslookup" is present
    
    Fatal error: No IPv4/IPv6 address(es) for "geekflare.com" available

    It was on CentOS 7 and if you are having the same issue then here is how you can fix it.

    This happens when a program can’t find any utility to resolve the IP or domain. You can install the bind-utils to fix the error.

    yum install bind-utils -y

    Run the program again and it should be ok.
