network SKILL.md skillB
network from bug-ops/zeph is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bug-ops/zeph/network@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Network diagnostics, DNS lookup, port scanning, and connectivity testing. Use when the user asks to check if a host is reachable, trace network routes, resolve DNS records, inspect open ports, debug HTTP requests, check SSL/TLS certificates, test bandwidth, diagnose network latency, or troubleshoot connectivity issues using ping, traceroute, dig, nslookup, netstat, ss, curl, and related tools.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Network Diagnostics
Before running commands, detect the OS and load the matching reference for
platform-specific syntax:
- **Linux** — `references/linux.md` (ss, ip, iptables/nftables, iproute2)
- **macOS** — `references/macos.md` (lsof, ifconfig, pfctl, networkQuality)
- **Windows** — `references/windows.md` (PowerShell: Test-NetConnection, Get-NetTCPConnection)
OS detection:
```bash
uname -s 2>/dev/null || echo Windows
```
## Quick Reference
| Task | Command |
|------|---------|
| Check host reachability | `ping -c 4 host` |
| Trace route to host | `traceroute host` |
| DNS lookup | `dig +short host` |
| Reverse DNS | `dig -x IP` |
| Check specific port | `nc -zv host port` |
| HTTP status | `curl -sI -o /dev/null -w "%{http_code}" URL` |
| SSL certificate | `openssl s_client -connect host:443 </dev/null` |
## Diagnostic Workflow
### Is a service accessible?
1. **DNS resolves** — `dig +short host`
2. **Host reachable** — `ping -c 2 host`
3. **Port open** — `nc -zv -w 3 host 443`
4. **HTTP responds** — `curl -sI -o /dev/null -w "%{http_code}" https://host`
5. **SSL valid** — `openssl s_client -connect host:443 </dev/null 2>/dev/null | openssl x509 -noout -checkend 0`

How to install
mdr add bug-ops/zeph/network@sha256:fc3b8629989a9330The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
