Tink vs ngrep
ngrep is a libpcap CLI that greps packets matching a BPF filter and a regex. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
ngrep greps packets. Tink answers “why is this VPS sick?”
Accidental sysadmins land on ngrep because ngrep -d eth0 'HTTP' port 80 shows payloads without a dashboard. Then disk is at 91%, nginx dies, and last night's regex hits do not say what to run. A filling /var is a Tink warning; it is not an ngrep match.
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 ngrep if you already want a packet grep on an SSH session. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | ngrep |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | apt/yum install ngrep, then ngrep -d eth0 'HTTP' port 80 every time traffic looks wrong |
| What you get | Working monitoring, diagnosis, and approved fixes | Matching packet payloads: regex hits on the wire, only while the grep is running |
| 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 interface, which BPF, which regex, and whether anyone was grepping when the flood started |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | libpcap grep. ngrep does not parse auth.log or propose a command |
| Configuration | None after install — heuristics and AI | Interface, snaplen, filter expression, and the regex you hope still matches |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read matching payloads yourself |
| Fix execution | Proposes and executes approved commands with an audit trail | Monitoring only — ngrep cannot drop the flood, restart nginx, or rotate a cert |
| Alerting | Built-in across 8 channels | None by default — ngrep is a live grep; paging is extra |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Live packets only — ngrep 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 — ngrep 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 ngrep either |
| Public status page | Shareable URL with 90-day history | Not included — ngrep has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a packet grep 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 + ngrep. No mechanic you text when /var filled |
| Learning curve | None — works after install | Low to launch; higher to map a regex hit to the process that filled the disk |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want a packet grep and will still SSH in when the box is sick |
When ngrep is the right choice
Keep using ngrep when you already want that exact job:
- Packet grep — you need regex-matched payloads, not a fleet digest.
- Wire-oriented — tcpdump dumps frames; ngrep is the grep on those frames.
- No extra service — a package on the box, not a hub, SaaS, or Telegram bot.
- No conversation layer wanted — some operators prefer a CLI and will never use a mechanic.
The real cost of “just run ngrep”
The package is easy to install. A working ops loop for five Linux boxes is not:
- A complete packet grep still means you SSH into the host and change the box by hand when it gets sick
- Host fill, nginx, certs, and SSH brute-force never appear unless you built extra checks
- A filling /var is a Tink disk warning on every scan — ngrep stays a live grep until you are looking
- A single VPS with nobody logged in still needs a mechanic, not another regex hit
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens ngrep after the outage, and every scan includes a diagnosis a quiet packet grep will not type.
No SSH homework. No silent host. One command install.
