netprobe

Overview ¶

Command netprobe is fairpeer's in-network probe binary (NETDEV_SPEC §5.1): run it ON a jump host inside the management network (copy it there manually for now — automated SFTP deployment ships later), point it at a CIDR, and it probes TCP ports and ICMP reachability from that network position — the only way to reach UDP/ICMP-dependent checks through a bastion (SSH tunnels are TCP-only). Output is JSON on stdout; nothing is installed, nothing persists: run-per-scan, delete-when-done.

Usage:

netprobe -cidr 10.30.2.0/24 [-ports 22,23,161] [-icmp] [-concurrency 50]
netprobe -ip 10.30.2.5 -ports 22,23
