RSRV Configuration Test Plan

Scope

This document describes some of the possible network configurations for RSRV and the expected results.

The expected results are given as the output various IOC shell commands (eg. epicsParamShow/casr/dbcar).

Preparation

This testing should be done on a computer with more than one physical/virtual network interface in additional to the loopback.

On Linux additional tun/tap virtual interfaces can easily be added. In the following examples the addresses 10.5.1.1 and 10.5.2.1 name two such interfacess. Additional interfaces may be present.

ip tuntap add dev tap0 mode tap
ip addr add 10.5.1.1/24 dev tap5
ip tuntap add dev tap1 mode tap
ip addr add 10.5.2.1/24 dev tap5

These can later be removed

ip tuntap del dev tap0 mode tap
ip tuntap del dev tap1 mode tap

Tests

Test #1 Defaults

The default configuration is for RSRV is to bind to the wildcard interface (0.0.0.0), and for libca to search on all local interfaces.
