exclude range/ip, discovery

hi!
How can I exclude IP from the search Discovery?

For example, I have Subnet (s) to scan: 172.17.0.0/16,
and I appear:

You can exclude ip / range? Host is already added to another ip (192.168.x.y)

I'm not a frequent user of that plugin. But to my knowledge, this would be a new feature which seems to be interesting. Of course, you may implement that and post a patch ...

Are you saying that you wish to ignore hosts that have already been discovered on a subnet with an identical sysName?

Please check the latest SVN. I believe it corrects this issue.

I understood it as a request for excluding certain IP subranges from being scanned. E.g. we used quite large class B private nets with a specific IP address policy. So the address ranges is "nearly unused" and it would speed up things excluding those unused areas

It's more like if, say for example, you have hsrp enabled for a router, don't add three devices to the device list for that single subnet. Or if the router is sitting on multiple subnets, don't add it again and again.

That's been incorporated into the latest code.

Network Discovery v 1.3

For example: WS-9

WS-9 config:

Code: Select all

 ip address 192.168.168.137 255.255.0.0
 ip address 172.17.7.254 255.255.255.0
 ip address 172.17.9.254 255.255.255.0

 network 172.17.7.0 0.0.0.255 area 1
 network 172.17.9.0 0.0.0.255 area 1

How do I hide (except IP) addresses do not need me?

I'm pretty sure this was fixed already in the latest release. Remove all of the entries and see if you can repeat that.

I removed all known hosts of Discovery (Console -> Utilities -> Clear Discovery Results), but after a while, the situation is repeated.
I can tell you do something to help to diagnose this problem?

It uses regex to find common hosts. I don't read regex. So, the findhosts.php will need a minor change. What it is yet, I don't know.

You can search for 'isDuplicateHost' in that file and noodle with the code. If you can fix it, I'll get it into the latest code.

please give a URL to the actual version plugin.

Apparently, we are talking about different versions

Very Thanks.
