Are you able to produce a patch, or do you want us to work on that?

I can give it a shot if only I was able to figure out how Netdisco and its dependencies development cycle works...

I've tried to patch some source files and then re-run netdisco-do or other components, but my modifications were not taken in account, so I thought that I've been missing some crucial point like compilation.

Can you please point me to some text describing how to apply local patches to Netdisco and test the modified code afterwards? I've been searching but I cannot find anything.

Sorry if it sounds like a newbie question, but I've only patched small scripts and no compilation was involved, never touched something written in Perl as large as Netdisco.

regards

Hi,
I am new to NetDisco and am not sure if there is a VM ready for use that
can used for quick deployment.
If this is not available, can Netdisco be installed on Linux machine?
Please also provide me the URL for downloading the Netdisco version 2 and
also the installation guide. I could only find version 1.3.3 on the
sourceforge page for Netdisco.

Regards,
Ahmer

No there isn't one, but the installation is easy.

Sure, here are the instructions:

Hello,

I installed a new netdisco 2.027007 and integrated the 
App-NetdiscoX-Web-Plugin-RANCID-2.003002. Generally, it works, I just have the 
situation that my rancid-devices are listed without fqdn, but netdisco does 
recognize them with fqdn. So the link that is provided by the plugin points to 
http://rancidurl/hostname.domain, but my rancid config is under 
http://rancidurl/hostname
I also have some devices, that are only accessible by IP, name resolution does 
not work there. Is there a way to modify the url that the plugin sets here?

Thanks and regards
Mana

Good afternoon,

I'm new to netdisco, and I'm running into an issue that I think is
probably simple to resolve, but I'm not sure how to proceed.

I installed netdisco 2.027007 on a CentOS 6.4 server, which went fine.
Given one of the core routers, it detected most of our Cisco routers and
switches, but that's where it stops, and where I get a little bit confused.

Most of our servers are in dell chassis, so they're connected to a switch
in the chassis (a Dell PowerConnect M6220, in most cases), which is
uplinked to one of the core routers.

When I discover a server manually, it collects all the proper information,
but doesn't pick up the Dell switch it's connected to.  Then, when I
manually discover the Dell switch, it collects all the information about
the switch, and on the "Neighbors" map, it shows that it's connected to
the router.  The "Ports" page shows the router in the "Connected Devices"
column with a little link symbol. Awesome.  Finally, when I view the
"Ports" list for the router, though, the Dell switch is nowhere to be
found, and it's not on the "Neighbors" map.

So that's confusing, but it gets a little bit more frustrating.

On the "Ports" page of the Dell switch, under "Connected Devices", for
each port it lists the MAC address, the hostname and the IP of the server
that's connected to that port, but it never ran a discovery on those
servers, so they don't exist as devices within netdisco.  If I discover
them manually, it doesn't create any kind of link between the Dell and the
server. (Though clicking on the IP will do a search for the ip, which
turns up the correct device, but it's not really a "link" as far as I can
tell.)

My guess is that I need to make some configuration changes to netdisco to
get it to treat the Dell as a router or a switch instead of a node, but I
don't really understand how netdisco works, and I'm having trouble finding
documentation on version 2 specifically, so I'm hoping someone can make
sense of my rambling and point me in the right direction.

Thanks,
Patrick

Hi Patrick,

Thanks for using Netdisco and the mail list. There's also an #IRC channel if you use that - #netdisco on freenode.

The "Ports" page shows the router in the "Connected Devices"
column with a little link symbol. Awesome.  Finally, when I view the
"Ports" list for the router, though, the Dell switch is nowhere to be
found, and it's not on the "Neighbors" map.

That could be a bug, as there shouldn't normally be asymmetric links in the web view. We'll come back to this.

On the "Ports" page of the Dell switch, under "Connected Devices", for each port it lists the MAC address, the hostname and the IP of the server
that's connected to that port, but it never ran a discovery on those
servers, so they don't exist as devices within netdisco. If I discover them manually, it doesn't create any kind of link between the Dell and the
server.

I think there's a misunderstanding of terminology here. Switches and routers are Devices. Servers, workstations, printers, etc, are Nodes. You can't drill down into a Node in the web UI as they're the 'leaf', so simply appear attached to the relevant switch port(s). There's no link symbol to a Node.

For the bug, if you can tolerate it for a little time I'd appreciate you waiting for the next release of Netdisco which has a few fixes in this area. Hope that's OK.

regards,
oliver.

Hello,

I'm new at netdisco and have a question.....
Is it possible to implement a script to get the needed information 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).

Stefan
