The
rtquery
utility is used to query a RIP
network routing daemon, such as
routed(8),
for its routing table by sending a
request or
poll command. The routing information in any
routing
response packets returned is displayed
numerically and symbolically.
The
rtquery
utility by default uses the
request command. When the
-p
option is specified,
rtquery
uses the
poll command, an undocumented extension to the
RIP protocol supported by the commercial
gated
routing product. When querying
gated
, the
poll command is preferred over the
request command because the response is not
subject to Split Horizon and/or Poisoned Reverse, and because some versions of
gated
do not answer the
request command. The
routed(8)
utility does not answer the
poll command, but
recognizes
requests coming from
rtquery
and so answers completely.
The
rtquery
utility is also used to turn
tracing on or off in
routed(8).
The following options are available:
-n
- displays only the numeric network and host numbers instead of both numeric
and symbolic.
-p
- uses the poll command to request full routing
information from
gated
. This is an
undocumented extension RIP protocol supported only by
gated
.
-1
- queries using RIP version 1 instead of RIP version 2.
-w
timeout
- changes the delay for an answer from each host. By default, each host is
given 15 seconds to respond.
-r
addr
- asks about the route to destination
addr.
-a
passwd=XXX
-
-a
md5_passwd=XXX|KeyID
- causes the query to be sent with the indicated cleartext or MD5
password.
-t
op
- changes tracing, where op is one of the
following. Requests from processes not running with UID 0 or on distant
networks are generally ignored by the daemon except for a message in the
system log.
gated
is likely to ignore
these debugging requests.
- on=tracefile
- turns tracing on into the specified file. That file must usually have been
specified when the daemon was started or be the same as a fixed name,
often /etc/routed.trace.
- more
- increases the debugging level.
- off
- turns off tracing.
- dump
- dumps the daemon's routing table to the current tracefile.
