Tink vs tshark
tshark is Wireshark's CLI packet dissector. It prints protocol trees matching a display filter. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
tshark decodes packets. Tink answers “why is this VPS sick?”
Accidental sysadmins land on tshark because tshark -i eth0 -Y http shows fields without a dashboard. Then disk is at 91%, nginx dies, and last night's pcap does not say what to run. A filling /var is a Tink warning; it is not a tshark http.request.uri.
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 tshark if you already want a packet dissector on an SSH session. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | tshark |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | apt/yum install tshark, then tshark -i eth0 -Y http every time traffic looks wrong |
| What you get | Working monitoring, diagnosis, and approved fixes | Dissected packets: protocol trees, fields, and streams, only while the capture 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 display filter, pcap disk fill, and whether anyone was dissecting when the flood started |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Wireshark CLI dump. tshark does not parse auth.log or propose a command |
| Configuration | None after install — heuristics and AI | Interface, snaplen, capture vs display filter, and whether you left -w running in tmux |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read protocol trees and field names yourself |
| Fix execution | Proposes and executes approved commands with an audit trail | Monitoring only — tshark cannot drop the flood, restart nginx, or rotate a cert |
| Alerting | Built-in across 8 channels | None by default — tshark is a live dissector; paging is extra |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Live packets only — tshark 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 — tshark 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 tshark either |
| Public status page | Shareable URL with 90-day history | Not included — tshark has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a protocol tree 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 + tshark. No mechanic you text when /var filled |
| Learning curve | None — works after install | Low to launch; higher to map an HTTP/2 frame to the process that filled the disk |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want a packet dissector and will still SSH in when the box is sick |
When tshark is the right choice
Keep using tshark when you already want that exact job:
- Packet dissection — you need protocol trees and display filters, not a fleet digest.
- Wire-oriented — tcpdump dumps frames; tshark decodes them; neither is a mechanic.
- 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 tshark”
The package is easy to install. A working ops loop for five Linux boxes is not:
- A complete protocol tree 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 — tshark stays a live dissector until you are looking
- A single VPS with nobody logged in still needs a mechanic, not another HTTP/2 frame
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens tshark after the outage, and every scan includes a diagnosis a quiet packet tree will not type.
No SSH homework. No silent host. One command install.
