=head1 NAME
|
||||
|
||||
netdisco-do - Run any Netdisco job from the command-line.
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
~/bin/netdisco-do <action> [-DISQ] [-d <device> [-p <port>] [-e <extra>]]
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This program allows you to run any Netdisco poller job from the command-line.
|
||||
|
||||
The C<-d> option will accept a hostname (that can be resolved to an IP with
|
||||
DNS), an IP address, or IP prefix (subnets in CIDR format). It can be any
|
||||
interface on the device known to Netdisco.
|
||||
|
||||
Note that some jobs (C<discoverall>, C<macwalk>, C<arpwalk>, C<nbtwalk>)
|
||||
simply add entries to the Netdisco job queue for other jobs, so won't seem
|
||||
to do much when you trigger them.
|
||||
|
||||
=head1 ACTIONS
|
||||
|
||||
=head2 discover
|
||||
|
||||
Run a discover on the device (specified with C<-d>).
|
||||
|
||||
~netdisco/bin/netdisco-do discover -d 192.0.2.1
|
||||
|
||||
=head2 discoverall
|
||||
|
||||
Run a discover for all known devices.
|
||||
|
||||
=head2 macsuck
|
||||
|
||||
Run a macsuck on the device (specified with C<-d>).
|
||||
|
||||
~netdisco/bin/netdisco-do macsuck -d 192.0.2.1
|
||||
|
||||
=head2 macwalk
|
||||
|
||||
Run a macsuck for all known devices.
|
||||
|
||||
=head2 arpnip
|
||||
|
||||
Run an arpnip on the device (specified with C<-d>).
|
||||
|
||||
~netdisco/bin/netdisco-do arpnip -d 192.0.2.1
|
||||
|
||||
=head2 arpwalk
|
||||
|
||||
Run an arpnip for all known devices.
|
||||
|
||||
=head2 delete
|
||||
|
||||
Delete a device (specified with C<-d>). Pass a log message for the action in
|
||||
the C<-e> parameter. Optionally request for associated nodes to be archived
|
||||
(rather than deleted) by setting the C<-p> parameter to "C<yes>" (mnemonic:
|
||||
B<p>reserve).
|
||||
|
||||
~netdisco/bin/netdisco-do delete -d 192.0.2.1
|
||||
~netdisco/bin/netdisco-do delete -d 192.0.2.1 -e 'older than the sun'
|
||||
~netdisco/bin/netdisco-do delete -d 192.0.2.1 -e 'older than the sun' -p yes
|
||||
|
||||
=head2 renumber
|
||||
|
||||
Change the canonical IP address of a device (specified with C<-d>). Pass the
|
||||
new IP address in the C<-e> parameter. All related records such as topology,
|
||||
log and node information will also be updated to refer to the new device.
|
||||
|
||||
Note that I<no> check is made as to whether the new IP is reachable for future
|
||||
polling.
|
||||
|
||||
~netdisco/bin/netdisco-do renumber -d 192.0.2.1 -e 192.0.2.254
|
||||
|
||||
=head2 nbtstat
|
||||
|
||||
Run an nbtstat on the node (specified with C<-d>).
|
||||
|
||||
~netdisco/bin/netdisco-do nbtstat -d 192.0.2.2
|
||||
|
||||
=head2 nbtwalk
|
||||
|
||||
Run an nbtstat for all known nodes.
|
||||
|
||||
=head2 expire
|
||||
|
||||
Run Device and Node expiry actions according to configuration.
|
||||
|
||||
=head2 expirenodes
|
||||
|
||||
Archive nodes on the specified device. If you want to delete nodes, set the
|
||||
C<-e> parameter to "C<no>" (mnemonic: B<e>xpire). If you want to perform the
|
||||
action on a specific port, set the C<-p> parameter.
|
||||
|
||||
~netdisco/bin/netdisco-do expirenodes -d 192.0.2.1
|
||||
~netdisco/bin/netdisco-do expirenodes -d 192.0.2.1 -p FastEthernet0/1 -e no
|
||||
|
||||
=head2 graph
|
||||
|
||||
Generate GraphViz graphs for the largest cluster of devices.
|
||||
|
||||
You'll need to install the L<Graph::Undirected> and L<GraphViz> Perl modules,
|
||||
and possibly also the C<graphviz> utility for your operating system. Also
|
||||
create a directory for the output files.
|
||||
|
||||
mkdir ~netdisco/graph
|
||||
~netdisco/bin/localenv cpanm Graph::Undirected
|
||||
~netdisco/bin/localenv cpanm GraphViz
|
||||
|
||||
=head2 show
|
||||
|
||||
Dump the content of an SNMP MIB leaf, which is useful for diagnostics and
|
||||
troubleshooting. You should provide the "C<-e>" option which is the name of
|
||||
the leaf (such as C<interfaces> or C<uptime>).
|
||||
|
||||
If you wish to test with a device class other than that discovered, prefix the
|
||||
leaf with the class short name, for example "C<Layer3::C3550::interfaces>" or
|
||||
"C<Layer2::HP::uptime>".
|
||||
|
||||
~netdisco/bin/netdisco-do show -d 192.0.2.1 -e interfaces
|
||||
~netdisco/bin/netdisco-do show -d 192.0.2.1 -e Layer2::HP::interfaces
|
||||
|
||||
=head2 psql
|
||||
|
||||
Start an interactive terminal with the Netdisco PostgreSQL database. If you
|
||||
pass an SQL statement in the C<-e> option then it will be executed.
|
||||
|
||||
~netdisco/bin/netdisco-do psql
|
||||
~netdisco/bin/netdisco-do psql -e 'SELECT ip, dns FROM device'
|
||||
~netdisco/bin/netdisco-do psql -e 'COPY (SELECT ip, dns FROM device) TO STDOUT WITH CSV HEADER'
|
||||
|
||||
=head2 location
|
||||
|
||||
Set the SNMP location field on the device (specified with C<-d>). Pass the
|
||||
location string in the C<-e> extra parameter.
|
||||
|
||||
~netdisco/bin/netdisco-do location -d 192.0.2.1 -e 'wiring closet'
|
||||
|
||||
=head2 contact
|
||||
|
||||
Set the SNMP contact field on the device (specified with C<-d>). Pass the
|
||||
contact name in the C<-e> extra parameter.
|
||||
|
||||
~netdisco/bin/netdisco-do contact -d 192.0.2.1 -e 'tel: 555-2453'
|
||||
|
||||

|
||||
|
||||
=head2 portcontrol
|
||||
