# llbl
"Let Localhost be Localhost" DNS server which resolves `*.localhost` to `127.0.0.1`.
It relies on `/etc/resolver`.
## Installation
```bash
go get github.com/ichiban/llbl/cmd/llbl
```
## Usage
By default, `foo.localhost` doesn't resolve to anything.
```console
$ ping -c 1 foo.localhost
ping: cannot resolve foo.localhost: Unknown host
```
Run `llbl` with `sudo`. While it's running, any domains that end with `.localhost` will be resolved as `127.0.0.1`.
```console
$ sudo llbl
Password:
INFO[0000] listen addr="0.0.0.0:62631"
```
```console
$ ping -c 1 foo.localhost
PING foo.localhost (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.048 ms
--- foo.localhost ping statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.048/0.048/0.048/0.000 ms
```
## Back story
I wanted to test a web app which can be accessed as `*.example.com` where `*` can be any strings.
So I looked it up how to configure /etc/hosts to resolve any `*.example.com` to localhost.
I stumbled upon [a stackoverflow answer](https://stackoverflow.com/a/20446931) that says there's no way to configure /etc/hosts that way. So, instead [I needed to run a local DNS server](https://passingcuriosity.com/2013/dnsmasq-dev-osx/).
For that purpose, [the domain has to be `*.test` but there's a proposal to use `*.localhost`](https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/).
I checked if `foo.localhost` works on my laptop. It didn't. So I made this.
