sbin/rtsol now shares source code with usr.sbin/rtsold.
sbin/rtsol is compiled separately for static linkage.

.Op Fl nv

|

.\"
|
||||
.Sh DESCRIPTION
|
||||
.Nm Rtsol
|
||||
sends router solicitation packet to the specified
|
||||
.Ar interface .
|
||||
If there is any router on the network, the router may respond by
|
||||
router advertisement packet.
|
||||
Router advertisement packet contains information about the network,
|
||||
the link-local address of the router, and so forth.
|
||||
The kernel will install the new routing information and address prefix
|
||||
for the
|
||||
.Ar interface ,
|
||||
according to the information.
|
||||
.Pp
|
||||
.Nm
|
||||
implements some quickhack code for notebook computers.
|
||||
.Fl n
|
||||
disables the behavior
|
||||
.Pq the flag stands for no tricks .
|
||||
.Pp
|
||||
If
|
||||
.Fl v
|
||||
is specified,
|
||||
.Nm
|
||||
will generate more messages.
|
||||
This is mostly for debugging.
|
||||
.Pp
|
||||
Router advertisement packet will be processed only if the
|
||||
node is configured as a host, not a router.
|
||||
To accept router advertisement packet,
|
||||
.Xr sysctl 8
|
||||
variables must be set as follows:
|
||||
.Bd -literal -offset
|
||||
# sysctl -w net.inet6.ip6.forwarding=0
|
||||
# sysctl -w net.inet6.ip6.accept_rtadv=1
|
||||
.Ed
|
||||
.Pp
|
||||
Typically this is done in system startup scripts, such as
|
||||
.Xr rc 8 .
|
||||
.\"
|
||||
.Sh RETURN VALUES
|
||||
The program exits with 0 on success, non-zero on failures.
|
||||
.\"
|
||||
.Sh SEE ALSO
|
||||
.Xr rtadvd 8 ,
|
||||
.Xr rtsold 8 ,
|
||||
.Xr sysctl 8
|
||||
.\"
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
