Building rConfig-sim from source

rConfig-sim is built with make. There are no code-generation steps and no external build tools beyond the Go toolchain.

Clone and build

git clone https://github.com/rconfig/rconfig-sim.git
cd rconfig-sim
make build

make build compiles both binaries into bin/ as static executables (CGO_ENABLED=0):

• bin/rcfg-sim — the SSH server
• bin/rcfg-sim-gen — the config generator

You can run them straight from bin/, or install them system-wide with make install.

Makefile targets

Target	What it does
make build	Compile both binaries into bin/
make test	Run unit tests (fast, no network)
make integration	Run integration tests (real SSH over loopback; build tag integration)
make bench	Run hot-path benchmarks
make vet	go vet, with and without the integration tag
make fmt	gofmt -s
make install	Install binaries, systemd unit, sysctl and limits drop-ins
make uninstall	Stop/disable units and remove installed files
make generate-configs	Wrapper around rcfg-sim-gen with env-var overrides
make deploy-aliases / make remove-aliases	Manage IP aliases via deploy/ip-aliases.sh
make clean	Remove build artifacts

Verifying the build

./bin/rcfg-sim --help
./bin/rcfg-sim-gen --help

Both print their full flag set with defaults — see the CLI reference.

Running the test suite

make test          # unit tests
make integration   # spins up real SSH listeners on loopback

The unit suite includes the deterministic-output tests that hash the generated config tree; see Determinism & seeds and Contributing.
