To get started with Netirk, install it via Go:
go install github.com/himaatluri/netirk
Usage
Basic Commands
Netirk offers a clean and easy-to-use CLI interface. Use the following commands for different operations:
Check Connectivity
Verify the response from a host and inspect SSL details if required.
netirk check --target <hostname> --verify-ssl </hostname>
Example
netirk check --target google.com --verify-ssl
Output:
Getting server certs... ➥ Cert: 0 ￫ CA: false ￫ Issuer: WR2 ￫ Expiry: Monday, 13-Jan-25 08:36:56 UTC ￫ PublicKey: -----BEGIN CERTIFICATE-----
Trace
Diagnose connection details, including DNS resolution time, connection latency, and TLS handshake information.
netirk trace --host <hostname> --port <port> </port></hostname>
Example 1
netirk trace --host https://amazon.com --port 8080
Output:
DNS Resolution done: 7.618718ms Connect Done: 26.686553ms Request failed: dial tcp 54.239.28.85:8080: connect: connection refused
Example 2
netirk trace --host https://amazon.com --port 443
Output:
DNS Resolution done: 7.553307ms Connect Done: 27.578134ms TLS Handshake Done: 83.745488ms Time to first byte: 147.988115ms
Running a Lightweight Server
Netirk also includes a basic HTTP server to test local networking setups.
netirk server
Example:
➜ netirk server Starting a simple HTTP server on port: 8080 2024/11/25 23:46:37 request: GET /host 2024/11/25 23:46:44 request: GET /health
You can use curl to interact with the server:
curl localhost:8080/host curl localhost:8080/health
Output:
hostname-prints/returned healthy
