A problem with the upgrade from earlier versions (in Windows). The NetXMS Server installer (full, not minimal) doesn't upgrade the Management Console (although the Administration Console component is marked in the installer window). As a result, after installation I have 2.0-M3 Server and 2.0-M1 Console which are incompatible with each other.

Yes, there was a bug in installer. I just uploaded updated installer to the web site.

Best regards,
Victor

PING subagent:
Since upgrade from V2.0-M2 to V2.0-M3 I have a problem with PING subagent, with no change in the existing configuration I get now always Latency=10k (=timeout) (Icmp.AvgPingTime).
We use NetXMS on Linux x64 compiled from sources. PING subagent is on the NetXMS server.
Is there any known problem?

VPN-connector Subnets tab:
Since V2.0-M3 I can't open the Subnets tab of an existing VPN-connector anymore, I get the following error:
"The currently displayed page contains invalid values." in the Windows x64 Java Console.

Wake-on-LAN:
Now Wake-on-LAN is not working anymore (managed or unmanaged node).

Hi,

seems that all of those related to changes in IP address handling. Are you using IP addresses or DNS names in PING subagent?

Best regards,
Victor

We use IP addresses in PING subagent config:
[ping]
DefaultPacketSize = 46
PacketRate = 4
Target = 172.16.50.1:host.doamin.intern


I've fixed broken WoL. If you are building from sources you can replace line 993 in file src/server/core/interface.cpp from


         UINT32 destAddr = htonl(addr.getAddressV4() | ~(0xFFFFFFFF << addr.getMaskBits()));


to


         UINT32 destAddr = htonl(addr.getAddressV4() | ~(0xFFFFFFFF << (32 - addr.getMaskBits())));


and recompile server.

Best regards,
Victor

Thanks Victor, I can confirm that fixed the one with Wake-on-LAN (for managed and unmanaged nodes).

Hi Victor, in this new update you fixed the broken SNMP in agents and that works great but now I am unable to use SNMP from the server netxms is installed on. It was working in version 2.0-M2. What happens is this:

1. I do a configuration poll on the netxms server node. SNMP is connected to and values read.
2. I try to do a SNMP walk from netxms on the local netxms server node and it fails or gives no results back.
3. If I then do another configuration poll on the netxms server node SNMP fails and isn't found.

I know SNMP works as I can SNMP walk with a separate program without any issues. I tried deleting the netxms server node and having it recreate it self but that did not help. Could it be something to do with the new IPv6 interfaces in this new version?

Basically, SNMP is working for all other nodes except the node netxms server is installed on.

To the "PING subagent" issue:
I made a network dump and saw the IP addresses the subagent uses are in reverse order:
set in agent config: 172.16.50.1
used from PING subagent: 1.50.16.172

I hope you have a short solution, I can fix in the source code.

Hi,

I fixed ping subagent. You can try to replace ping.cpp and ping.h in src/agent/subagents/ping with attached ones and recompile agent. As side effect, it should also work correctly with IPv6 targets (IPv6 addresses in config should be enclosed in square brackets).

Best regards,
Victor

Hi Victor. Thanks for the quick fix. PING subagent is working again! Thanks, Dani

Hi,

I have found a couple of problems with ping after the upgrade from 2.0-M2 to 2.0-M3.

One is the ping agent not working, but have got around that by reversing the IP addresses in the conf file.

The second is the ICMP proxy is not working. I would assume it is related to the same issue as the ping agent?

Thanks, Brett.

Hi,

Another odd thing I have noticed.

I have some win2k3 servers and they are reporting the wrong netmask for interfaces. They have a /23 netmask but NetXMS is reporting /24 and I am getting warnings about the incorrect netmask. Polled with agent.

Also I have two APC UPS units polled via SNMP proxy that are reporting /0 netmask when they have a /24 netmask. Again am getting netmask warnings logged. All other SNMP devices polled via the proxy are reporting correct netmask.

Have done a check on the DB and there are no issues detected.

Netmask was correct in 2.0-M2, and I have tried doing a full configuration poll since upgrade.

Thanks, Brett.

We also see /0 netmasks instead of /24 on HP printers since upgrade from M2 to M3 (server on Linux x64 built from sources).
