<![CDATA[Active Discovery on 2.0-M4]]>Hi,

at first I installed server 2.0-M4. I setup Active Discovery for two subnets 192.168.10.0/24 and 192.168.11.0/24. The server was in subnet 192.168.10.0/24. Active Discovery found nodes in subnet 192.168.10.0/24 but no node in subnet 192.168.11.0/24. I removed this version and I installed version 1.2.7 with the same settings of Active Discovery. This version found nodes in subnets 192.168.10.0/24 and 192.168.11.0/24 without any problems
Any idea?

Thanks
Ladislav

Best regards,

at first I had no filter. And I also tried to setup filter only for subnet 192.168.11.0/24. But situation was the same in both cases.

If node will be added to NetXMS MAC address will be replaced with correct one read from ARP cache later on. Do you have sny discovery filters that may prevent nodes from being added?

Victor

version 2.0-M5 partly helped. I checked log and server found nodes from subnet 192.168.11.0/24 (but every node has MAC 000000000000  - ?) , but the server didn't add them to NetXMS

Thanks

there is a bug in active discovery code (it was brojken when we add IPv6 support in 2.0-M3). I fix it in 2.0-M5.

Best regards,
Victor

I setup debug 6. In log was
..
Starting active discovery check on range 192.168.11.1 - 192.168.11.255
Active discovery - node 192.168.11.127 responds to ICMP ping
..
Finished active discovery check on range 192.168.11.1 - 192.168.11.255
..

192.168.11.127 was only one address from subnet 192.168.11.0/24 in log.
But node 192.168.11.127 doesn't exist. For example it exists node 192.168.11.34 but server didn't check it. I tried to ping from server to 192.168.11.127 - no response and to 192.168.11.34 - response Ok.

Thank you

Ladislav

try to run server with debug level 6 and check what's in the log regarding active discovery.

Best regards,
