nmap is a network mapper that finds hosts and open ports. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
Accidental sysadmins land on nmap because nmap -sV localhost shows what is listening without a dashboard. Then disk is at 91%, nginx dies, and last night's port table does not say what to run. A filling /var is a Tink warning; it is not an nmap open port.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep using nmap if you already want a port map from the outside. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | nmap |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | apt/yum install nmap, then nmap -sV -p- host every time you wonder what is open |
| What you get | Working monitoring, diagnosis, and approved fixes | A scan report: hosts, ports, services, and versions, only while you run it |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Open source. You still pay the person who SSHs in after the outage |
| Hidden costs | None — fully managed | Which CIDR, which timing template, noisy SYN scans, and whether anyone scanned before Redis hit the internet |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Network mapper. nmap does not parse auth.log or propose a command |
| Configuration | None after install — heuristics and AI | Targets, ports, scripts, and whether -Pn hid a host that was actually down |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read port tables yourself |
| Fix execution | Proposes and executes approved commands with an audit trail | Scanning only — nmap cannot bind Redis to localhost, restart nginx, or rotate a cert |
| Alerting | Built-in across 8 channels | None by default — nmap is a one-shot scan; paging is extra |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Live ports only — nmap does not forecast fill time or a quiet NIC going bad later |
| SSH brute-force detection | Built-in — parses auth.log every scan | Not included — nmap does not read host auth.log or journald |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | If the host is down you cannot SSH into nmap either |
| Public status page | Shareable URL with 90-day history | Not included — nmap has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a port table is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire something else into PagerDuty |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | SSH + nmap. No mechanic you text when /var filled |
| Learning curve | None — works after install | Low to launch; higher to map an open 6379 to the process that should not be public |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want a port map and will still SSH in when the box is sick |
Keep using nmap when you already want that exact job:
The package is easy to install. A working ops loop for five Linux boxes is not:
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens nmap after the outage, and every scan includes a diagnosis a quiet port table will not type.
No SSH homework. No silent host. One command install.
