- Refactoring the interface list. It now supports dynamically
added/removed interfaces in a more consistent manner and reloading
the configuration file.
- Add initial support for control socket. RA information in the
daemon can be obtained by rtadvctl(8) instead of SIGUSR1 in a similar
manner to ifconfig(8). The information dump has been removed in favor of it.
(reload the configuration file)
# rtadvctl reload
(show RA messages being sent on each interfaces)
# rtadvctl show
em0: flags=<UP,CONFIGURED,PERSIST> status=<RA_SEND> mtu 1280
DefaultLifetime: 30m
MinAdvInterval/MaxAdvInterval: 3m20s/3m20s
AdvLinkMTU: <none>, Flags: O, Preference: medium
ReachableTime: 0s, RetransTimer: 0s, CurHopLimit: 64
AdvIfPrefixes: yes
(show RA messages being sent only on em0)
# rtadvctl show em0
(rtadvctl -v show provides additional information)
# rtadvctl -v show em0
em0: flags=<UP,CONFIGURED,PERSIST> status=<RA_SEND> mtu 1280
DefaultLifetime: 30m
MinAdvInterval/MaxAdvInterval: 3m20s/3m20s
AdvLinkMTU: <none>, Flags: O, Preference: medium
ReachableTime: 0s, RetransTimer: 0s, CurHopLimit: 64
AdvIfPrefixes: yes
Prefixes (1):
2001:db8:1::/64 (CONFIG, vltime=30d, pltime=7d, flags=LA)
RDNSS entries:
2001:db8:1::128 (ltime=2m40s)
(stop rtadvd)
# rtadvctl shutdown
A remaining issue when reloading the configuration file is that
during that period rtadvd cannot communicate with rtadvctl due to some
additional RA sending for graceful shutdown. This will be fixed later.
