Conﬁguring gated

Troubleshooting gated

gdc determines the state of gated and produces a reliable exit status during errors, which is useful in shell scripts that manipulate gated. The syslogd facility is used to log all the commands and error messages generated during gdc operation. gated uses these log messages to provide an audit trail of operations performed on the daemon.

For more information, type man 1M gated at the HP-UX prompt.

The gated Routing Table

Sending gated a SIGINT signal causes gated to write information about interface conﬁgurations, task information, and routing tables to the /var/tmp/gated_dump ﬁle.

The ripquery Tool

You can use the /usr/sbin/ripquery support tool to query gated for RIP routing information. ripquery sends two types of commands: a POLL command and a RIP request command. gated responds to a POLL command by listing all routes learned from RIP that are in its routing table. This does not include the interface routes for the local network or routes from other protocols that are announced through RIP. When gated receives a RIP request command on a interface, it announces routes via RIP on that interface. This includes routes from other protocols that are imported by gated on the node.

You can use ripquery with the -poption to query other non-gatedRIP routers. With this option, ripquery initially sends POLL commands and then, if there is no response, sends RIP request commands. The default query (POLL commands) sent by ripquery may not be supported by all RIP routers. For more information, type man 1M ripquery at the HP-UX prompt.

The ospf_monitor Tool

You can use the /usr/sbin/ospf_monitor support tool to query OSPF routers for information on OSPF routing tables, interfaces, and neighbors, as well as data on AS external databases, link-state databases, error logs, and input/output statistics. Running the ospf_monitor command displays a prompt that allows you to enter interactive commands. For details on using this tool, type man 1M ospf_monitor at the HP-UX prompt.
