NAME
rtquery
- query routing daemons for their routing tables
SYNOPSIS
rtquery
[-np1]
[-w timeout]
[-r addr]
[-a secret]
host ...
rtquery
[-t op]
host ...
DESCRIPTION
rtquery
is used to query a RIP network routing daemon,
routed(8)
or
gated(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.
rtquery
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
gated(8).
When querying
gated(8),
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.
rtquery
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(8).
This is an undocumented extension RIP protocol supported only by
gated(8).
- -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(8)
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.
