Grp is a extremely simple radsec proxy written in Golang: it only supports
forwarding packets incoming from the TLS 1.2 connection to a radius UDP backend.
It was my first serious Golang program (needs a rewrite...) but the version
v0.1.0 is stable and battle tested serving hundreds of wifi hotspots.
It is well suited for deployment on containers as it keeps itself in the
foreground, logs to stdout and is configured only through environment
variables:
GRP_PORT: port to listen. Default: 2083.
GRP_CA_FILE: CA certificate file. Default: ca.crt.
GRP_CERT_FILE: server certificate file. Default: server.crt.
