sh# dbus-send --system --type=method_call --print-reply
--dest=org.freedesktop.sssd.infopipe /org/freedesktop/sssd/infopipe
org.freedesktop.DBus.Introspectable.Introspect | grep -C 2 Ping
</interface>
<interface name="org.freedesktop.sssd.infopipe">
<method name="Ping" />
<method name="ListComponents">
<arg type="ao" name="components" direction="out"
/>
```
