RTQUERY(8)              OpenBSD System Manager's Manual             RTQUERY(8)

NAME
     rtquery - query routing daemons for their routing tables

SYNOPSIS
     rtquery [-np1] [-w timeout] [-r addr] host ...

DESCRIPTION
     rtquery is used to query a 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 nu-
     merically and symbolically.

     rtquery by default uses the request command.  When the -p option is spec-
     ified, rtquery uses the poll command, an undocumented extension to the
     RIP protocol supported by gated(8). 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 does not answer the Poll
     command, but recognizes Requests coming from rtquery and so answers com-
     pletely.

     rtquery is also used to turn tracing on or off in routed(8).

     The options are as follows:

     -n      Normally network and host numbers are displayed both symbolically
             and numerically.  The -n option displays only the numeric network
             and host numbers.

     -p      Uses the poll command to request full routing information from
             gated(8). This is an undocumented extension RIP protocol support-
             ed only by gated(8).

     -1      Query 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
             Ask about the route to destination addr.

     -t op   Change tracing, where op is one of the following.  Requests from
             processes not running with UID 0 or on distant networks are gen-
             erally ignored by the daemon except for a message in the system
             log.

               on=tracefile
                       Turn 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 trace-
                       file.
