srv-shim

SRV record support for legacy systems. Built on top of plumber, part of the 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 (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
