Stupidly simple command line tool to resolve and ping hostnames.
|
|
|
|
|
|
|
|
|
|
I just use the binary to troubleshoot connectivity issues in scratch/alpine containers that don't have ping/dig/curl/wget.
|
|
|
|
|
Just copy the binary to the container, and problem solved.
|
|
|
|
|
|
|
|
|
|
The binary has to be built with `CGO_ENABLED=0` to avoid problems with alpine-based images.
|
|
|
|
|
|
|
|
|
|
Example of use:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
pingish www.google.es
|
|
|
|
|
```
|
|
|
|

# Server
|
|
|
|
|
|
|
|
|
|
You can start a server that will accept requests on `/ping?host=<target>`, using the `--server` flag. e.g.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
pingish --server
|
|
|
|
|
```

To run it as a normal user in ubuntu, you might need to configure your host first: `sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"`
|
|
|
|
|
|
|
|
|
|
And/or set the capabilities of the binary: `sudo setcap cap_net_raw=ep pingish`
