PortcheckR

PortcheckR is a small CLI tool to check reachability of ports and services on a host, aggregate the results, and optionally send a report by email.

Features

• Check multiple targets with -P port:PROTO:init (example: 21:FTP:1).
• Per-protocol handlers (FTP, SMTP/SMTPS, POP3/POP3S, IMAP/IMAPS, SSH, TELNET, HTTP/HTTPS, etc.) with a TCP fallback.
• Output combined report to stdout and optionally send it by email when -M is provided.
• Use --mail-test to force sending the report even when no NG (failure) occurred.

Requirements

• Rust (stable toolchain)
• Network access to target host and SMTP server when sending mail
• ICMP (ping) checks may require root privileges on some systems

Build

cargo build --release

Usage examples

• Basic check and print:

./target/release/portcheck -H example.com -T 5 -U MyUnit -P 80:HTTP:1 -P 22:SSH:1

• Send report by mail when an NG is detected (default mail server is localhost:25):

./target/release/portcheck -H host -T 5 -U MyUnit -P 21:FTP:1 -M ops@example.com -S mail.example.com:587 -F portcheck@example.com

• Mail test: send report even if all checks are OK:

./target/release/portcheck -H host -T 5 -U MyUnit -P 80:HTTP:1 -M ops@example.com --mail-test
