# srv-shim

SRV record support for legacy systems.  Built on top of [plumber](https://github.com/the-tetanus-clinic/plumber), part of the [discotech](https://github.com/the-tetanus-clinic/discotech) suite.

It works by intercepting calls to getaddrinfo, which would normally fail due to reliance on A/AAAA records, and using SRV instead for names prefixed with an underscore.

#### Compile-Time Prerequisites

1. [Rust](https://www.rust-lang.org/install.html) (stable recommended but not required)

#### Building

```

cargo build

```

Now, `target/debug/libsrvshim.so` should exist.

#### Usage

Linux/FreeBSD:

```

LD_PRELOAD=target/debug/libsrvshim.so \

curl _my-service._tcp.domain

```

You may also create an entry in `/etc/ld.so.conf` to cause it to be loaded in all processes on the system.

OSX:

```

DYLD_INSERT_LIBRARIES=/abs/path/to/libsrvshim.so \

DYLD_FORCE_FLAT_NAMESPACE=YES \

curl _my-service._tcp.domain

```
