na_rtsold - router solicitation daemon
rtsold [ -dD1 ] interface
rtsold [ -dD1 ] -a
rtsold -k
is the daemon program to send ICMPv6 Router Solicitation
messages on the specified interfaces. If a node
(re)attaches to a link, rtsold sends some Router Solicitations
on the link destined to the link-local scope allrouters
multicast address to discover new routers and to
get non link-local addresses.
rtsold should be used on IPv6 host non-router node only.
Specifically, rtsold sends at most 3 Router Solicitations
on an interface after one of the following events:
Just after invocation of rtsold daemon.
The interface is up after a temporary interface failure.
rtsold detects such failures by periodically probing to
see if the status of the interface is active or not. Note
that some network cards and drivers do not allow the
extraction of link state. In such cases, rtsold cannot
detect the change of the interface status.
Once rtsold sends a Router Solicitation, and receives a
valid Router Advertisement, it refrains from sending additional
solicitations on that interface, until the next
time one of the above events occurs.
When sending a Router Solicitation on an interface, rtsold
includes a Source Link-layer address option if the interface
has its link-layer address.
-
-a
- Autodetect all outgoing ipv6 interfaces. rtsold
will try to find all non-loopback, non-p2p and
IPv6-capable interfaces. If rtsold finds multiple
interfaces, it will send out probes on all of them.
-
-d
- Enable debugging.
-
-D
- Enable more debugging including to print internal
timer information.
-
-1
- Perform only one probe. Transmit Router Solicitation
packet until valid Router Advertisement packet
arrives all the interfaces more than once, then
exit.
-
-s
- Dump output to /rtsold.dump
-
-k
- Kill rtsold daemon.
