Hi Oliver
Glad you like it and thanks for this very quick Netdisco2 port, I'll
certainly use that somewhen in the future :)
Inclusion in Netdisco2 would be fantastic. As the cpanlib stuff is no
longer included, I see no problem in applying the Netdisco license to
it, I'll change it and send you a pull request.

I do not think it is a problem but you need to install everything from cpan
following the instructions on the site Oliver gave you.
As far as the postgresql error is concerned, if I recall properly
Postgresql uses ident authentication out of the box. So any local user
should be able to connect to a local database if they are given rights in
the database schema. But that is a postgres issue, not a netdisco one
properly speakin ;-), so consult your local copy of the postgresql
documentation to see how it works in fedora 16.

Great, many thanks! I'll include this in the next release of Netdisco
2, then.

Hi Christian,
That's fantastic, many thanks!! I love the extensible design for
each
target platform.
I forked the repo and ported the system to Netdisco 2:
https://github.com/ollyg/netdisco-sshcollector
I made several changes to use modules and code in this fork, to
reduce
the dependencies and take advantage of the ND2 libraries:
* uses ND2 check_mac and store_arp
* resolve DNS of all ARPs and store that with the ARP
* use MCE instead of Parallel::ForkManager and Cache::FileCache
* use ND2 config instead of local config file
* add Makefile.PL so it can be shipped to CPAN
* debug and other minor things in the ND2 style
We could, in due course, include this in the Netdisco 2 distribution
(although the licenses are different, and I need to look into the
implications of that).
regards,
oliver.

Hi
We recently used Netdisco (1.x) in an environment with lots of F5
BigIP
and Cisco ACE balancers. Both do not support obtaining ARP entries
by
SNMP, so we made a script to do it by ssh.
The individual device types are implemented as Perl modules, so
adding
additional hardware should come down to providing the SSH commands
or
maybe an Expect dialogue.
We've seen that there has been some talk about similar cases from
time
to time on this list, so we made it available on github:

That's a nice feature request, so I've just implemented it and this
will be in the next point release.
It's just a little bit awkward that you have to first do a failed
search to get to the Device search tab, but then you will see new
Neighbor ID and Neighbor Type fields in which to search.

I read now a lot of source code and found mac suck do more then the
minimalistic script you showed?
For only pushing mac addresses into the netdisco the script is
probably
enough.
My switch (DGS-1210) doesn't give not enough snmp informations like
vlans. With a script and "debug info" I get the mac address table
with
vlans.
Do you have a hint for me if it's better to extend the netdisco
discover
and mac suck scripts or should I write complete new scripts?
In the next point release of Netdisco 2 will be a helper script called
netdisco-sshcollector which will retrieve the ARP table from any device
supporting SSH command line display of the data. We just need the
command to run, to train the script.
For MAC address tables there is currently no support. Please let us
know if this is required, again with an example if you can.
regards,
oliver.

from
a switch, router or firewall?
Background is, I found a lot of systems I couldn't get the MAC
address
table with snmp, but with scripts over ssh or telnet.
It could use the same technique rancid use (expect).
There's a script which came with Netdisco 1, but it hasn't (yet)
been
ported to Netdisco 2.
http://sourceforge.net/p/netdisco/code/ci/master/tree/bin/firewall_arp
If you're handy with Perl, you could start with this and perhaps the
RANCID config generator script we have with Netdisco 2, and create a
mashup (inserting entries into the node and node_ip DB tables).

Sorry I completely got the wrong end of the stick...
For searching nodes (rather than devices) this can be done, I'll look
into it.
