Ssh Listening Service Snapshot Ss Or Netstat Fallback

Enumerates locally listening TCP/UDP sockets using ss -tuln with stderr suppressed and limits output to the first 20 lines. If ss is unavailable, it falls back to netstat -tulpn, also truncated to 20 lines. This conditional snapshot indicates automated network service discovery to quickly assess exposed ports and potentially identify competing services, security tooling, or pivot opportunities.
