NAME
fjorker - minimalistic ICMP echo request/reply implementation
SYNOPSIS
fjorker host

DESCRIPTION
fjorker is a secure-by-default ICMP echo request/reply implementation
that follows OpenBSD's philosophy of minimalism and security.
Unlike traditional ping implementations, fjorker:
* Minimizes information disclosure about the source host
* Uses random identifiers instead of process IDs
* Validates sequence numbers in responses
* Has minimal code base for better security
EXAMPLES
