IP Scanner and SNMP Scanner Tool
Introduction
The IP scanner and SNMP Scanner Tool is used to discover existing hosts in an IP address range. If these hosts supports SNMP they are fully discovered with SNMP. The LoriotPro IP scanner and SNMP scanner tool updates the LoriotPro directory with the found hosts and applies the polling parameters. In a short delay the discovered host are under polling and monitoring.
The IP scanner and SNMP Scanner tool is very useful to discover hosts that do not use a default router and therefore that cannot be discovered by the LoriotPro SNMP discover process (no arp entries in its table).
The IP scanner function could be used to discover hosts on network portions where SNMP is not authorized or not activated.
The IP scanner and SNMP Scanner tool can be started
for a one shot discover.
The IP scanner and SNMP Scanner tool optionally
fills the Directory with new discovered objects.
Example
Statring IP scanner
From the contextual menu of a network object, select the option:
IP Scanner
Remark: If you want to add the new discovered objects in
a specific container, you should preliminary select it in the Directory.
If you start it with a network object as default object, the IP address range
will be automatically set with the right value.
IP Scanner
The IP Start Address field and IP Stop Address field are set with the right IP address range.
The scan could be performed either with the ICMP (Ping) or the SNMP version V1/V2c protocole.
If you check the ‘Snmp Scan’ option, the process will use RO Snmp Community to carry out the request.
If you want that the discovered hosts are inserted in the Directory, you should check the ‘Add / Update Hosts Database’ option.
Table of options of the IP Scanner tool
| Options |
functions |
| Add/Update Entry |
If this option is checked, the discovered hosts will be added to the Directory. Remark: If this option is not checked, the other options of the ‘Add /Update Hosts Database’ zone are not used. |
| DNS Resolve |
The tool tries to resolv the host name with a DNS query. Remark: This option slows down the scanning drastically. |
| Put In Network If Exist |
If a network container with the right IP network already exists in the Directory, dicovered hosts are directly put in it. Remark: Regarding the network mask used, it is thus possible to have assignation errors. |
| Icmp Polling |
Created hosts will be polled with ICMP ( each 60 s) |
| Snmp Polling |
Created hosts will be polled with SNMP ( each 60 s) |
| Enable Discover Scanning |
Hosts will be used by the Discovered process Remark: Read the chapter discussing about the Discover process for more details. |
