Another finding fron debug userdb

There is a message
UpdateLDAPUser(): User with name "XYZ" already exists. Unique user name have been generated: "XYZ_LDAP6756"

Then server crashes and in the user database the new generated user " XYZ_LDAP6756" does not exists.

In our company are the users partionally managed based on user HR database. So when is an employe fired, the account in LDAP/AD remains, but the attribute CN (Full Name) is prepended with "S_". NetXMS ldapsync generate new user. So was it working up to version 5

When delete the LDAP user "XYZ" in Netxms, the sync ends without crashing.

Hello,
my NetXMS service on Windows server 2019, MariaDB crashes when start ldap sync. LDAP server is connected, can read data, then starts update the dababase and crashes

output from debug ldap 4

LDAPConnection::initLDAP(): Connecting to LDAP server
LDAPConnection::initLDAP(): servers="X.Y.X.Y:389" port=389 secure=false
LDAPConnection::syncUsers(): search base DN = OU=##############
LDAPConnection::fillLists(): hook script is empty
LDAPConnection::fillLists(): Found entry count: 714

...

LDAPConnection::closeLDAPConnection(): disconnect form LDAP server
LDAPConnection::syncUsers(): read completed, updating user database

now is server terminated

When delete all LDAP users and groups, the sync is ending successfully, but after some time have the same behaviour. Have tried change to the different LDAP search bases and maybe, there are problems with one specific OU with 211 objects. Can you give me a some advice how to activate the right debug?

Thank you. Martin

Only confirmation. The upgrade was successfull now.
Thank you. Martin

Perfect. Thank You very much.

There is not a link_styling_script field (currently running 4.5.6 version(restored from backup)

There is result of query as .csv attachment
SELECT id,filter FROM network_maps WHERE filter <> '';

network_maps.csv

.. have backups, have restored the database. Look's nobody else is observing the same issue. Try activate MariaDB logging if you are ending on updating network maps

.. "Prepare UPDATE network_maps SET link_styling_script=?,filter=? WHERE id=?"

Database log show some processing and is ending with "Prepare UPDATE network_maps SET link_styling_script=?,filter=? WHERE id=?"

In MariaDB log appear message:

Hello,

Hello Filipp,
I forgot to mention, it is MS windows server based installation. For testing have installed a new NetXMS server with sqlite DB and with webui. There is nothing configured, empty. Created the new map, then entered in the map .. and the error message arise. Jetty logs are attached.
The same bahaviour have in production installation NetXMS 4.4.4 + MariaDB + webui. When try open the map, error message appear and map is not displayed.

Hello, have the same question, the same error.

The error ist there in new web gui when display the map. 
Failed to register resource: generated/6b33fe9d.png
Cannot tell since is occuring, but it is there in 4.4.4, 4.4.3 and earlier versions. I tried make clean fresh test server installation and there is the same error.

Hello,
I am using Object Filter in Netxms L2 topology maps. The Object Filter code is lost after every Netxms service restart. Only the "Filter objects" checkbox remain checked. Have you the same experience? I am observing this behaviour from some 3.x version, maybe 3.1 upwards.

Netxms server 3.5.90 running on W2019 server, MariaDB.

Hello Viktor, the port names on links are the same, identical.
Need to mention, the discovery radius is the default (3) and the seed nodes have overlapping radius, it mean, the seed nodes are less than 3 hops. When remove the seed nodes and delete the links, the new links are created correctly. So the @JuraSSik is probably directing to right direction ...
Martin

Hello can somebody explain why are multiple links generated on my maps? And how prevent them.
I think it come with some of 3.0 or 3.1 version. The version had new feature "consolidate multiple nodes in one". I am using Cisco 3650 with hsrp/vrrp as core switches (and up to this version had for these switches multiple objects automaticaly generated). The rest are Cisco SMB 300, 350. Maps are created L2 with multiple seeds.

Thank you. Martin

Thank you, will wait for new release.

Hello Tomas, to be exactly I have a problem with NetObj's "TYPE attribute" when the object is Node.
As mentioned in Documentation, the Node class should inherite all attributes of NetObj class, but the
n->type returns "ERROR: Script finished with error: Error 15 in line XX: Unknown object's attribute"

It happen when the object is node.

The Title of this post should be probably
 The type attribute of NetObj cannot be determined when the object is node - Error Unknown object's attribute"

node=10506;

nodeObject=FindObject(node);

// this is a Node
println("FindObject - Class of node object: " . node . " is " . classof(nodeObject));

try {
println("Type of node object: " . nodeObject->type);
} catch {
  println("Query nodeObject->type. This error should not be displayed, since Node should have the TYPE attribute inherited from NetObj");
}

The function instanceof is not known im my system.
I am currently running 2.0.1 version.

In my case FindObject function returns different classes for Node and Container, but should return only the generic class as mentioned in Documentation.

println(classof(FindObject(10506)));  //10506 is Node, FindObject returns "Node"
println(classof(FindObject(219)));  //219 is Container, FindObject returns "NetObj"

It is not generally big problem, but it differs from the function description in Documentation pages and source code comments.

Martin

According to source codes, the function should return generic object class or null
/**
 * Find object
 * First argument: object id or name
 * Second argument (optional): current node object or null
 * Returns generic object or null if requested object was not found or access to it was denied
 */

If I call the function with a node as argument
o=FindObject(nodeid);
the 
o->type
returns: ERROR: Script finished with error: Error 15 in line XX: Unknown object's attribute

With container ID as parameter is not problem.

So I think the function is returning Node pointer when the argument is the node.

From my point of sight is it wrong behaviour. For this purpose exist FindNodeObject.

Martin

 

Code example
sub main() {

n=FindObject(10506);  // node class type

  println("Name: " . n->name . " ID: " . n->id);
  println("snmpSysName: " . n->snmpSysName); // WRONG - returns a snmpSysname value
  println("Type: " . n->type);  //WRONG - shoul return "2", but returns
            // - ERROR: Script finished with error: Error 15 in line XX: Unknown object's attribute
 
n=FindObject(219);  //Container class type

  println("Name: " . n->name . " ID: " . n->id);
  println("snmpSysName: " . n->snmpSysName); //CORRECT error message, snmpSysName does not exists in netobj"
                  // - ERROR: Script finished with error: Error 15 in line XX: Unknown object's attribute
  println("Type: " . n->type);  //CORRECT - returns "5"

}
