DESCRIPTION
Thertquery
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.
Routed(8) 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 bygated
. -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.
