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.
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 |
Keep using ngrep 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 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.
