grp

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.

• GRP_KEY_FILE: certificate key file. Default: server.key.

• GRP_RADIUS_HOST: radius backend hostname. Default: localhost.

• GRP_RADIUS_PORT: radius backend port. Default: 1812.

• GRP_RADIUS_ACCT_HOST: radius accounting backend hostname. Default: localhost.

• GRP_RADIUS_ACCT_PORT: radius accounting backend port. Default: 1813.

• GRP_RADIUS_TIMEOUT: timeout for radius responses. Default: 10s.

• GRP_IDLE_TIMEOUT: idle timeout for the TLS connection. Default: 60s.
