Java Getting Name/Description for OIDs in MIB

由 末鹿安然 提交于 2019-12-01 05:25:28
I am programming a network management system, and need to be able to print out meaningful names behind the OIDs that are received from SNMP traps. Due to the nature/size of this system, it would not be a good idea to manually map every OID to a meaningful name for every MIB on every device that is being used. With that said, is there a free (commercial use) way of automatically pairing name/description with their respective OID for all OIDs in a MIB; and then those pairings be used in a Java program? In other words, is there a tool or method that will convert a MIB tree to Java objects that

What is a good way to show a floating point number via SNMP?

由 我与影子孤独终老i 提交于 2019-11-30 20:40:36
I am coding an SNMP Agent. I need to send values that have a decimal point to an SNMP Manager. I have a couple options: Truncate the number. Multiply by a constant. Ask Stackoverflow. If I truncate the number I lose a lot of information that I need. If I multiply by a constant, then the manager will display strange units that the end-user would rather not see. (grams instead of kilograms). So, I'm doing option 3. What do I do? The usual, standard way this is done is to define a TEXTUAL-CONVENTION with an integral type (such as Integer32 or Unsigned32) and a DISPLAY-HINT with "d-N" format,

net-snmp sample code to parse MIB file and extract trap related information from it

由 偶尔善良 提交于 2019-11-30 14:18:17
I am using the net-snmp C library on Windows. I want to parse trap-related information from the MIB files. I need some sample code to do this. I didn't find anything useful on http://www.net-snmp.org/ Rahul Here is some sample code to parse MIB files using the net-snmp library. Before you use this code you need to refer or add the Include and Lib directories of net-snmp in your project properties: #include "stdafx.h" #include <net-snmp/net-snmp-config.h> #include <net-snmp/net-snmp-includes.h> #include <net-snmp/definitions.h> #include <net-snmp/library/tools.h> #include <net-snmp/mib_api.h>

Delphi: Get MAC of Router

由 半城伤御伤魂 提交于 2019-11-30 09:17:53
I am using Delphi and I want to determinate the physical MAC address of a network device in my network, in this case the Router itself. My code: var idsnmp: tidsnmp; val:string; begin idsnmp := tidsnmp.create; try idsnmp.QuickSend('.1.3.6.1.2.1.4.22.1.2', 'public', '10.0.0.1', val); showmessage(val); finally idsnmp.free; end; end; where 10.0.0.1 is my router. Alas, QuickSend does always send "Connection reset by peer #10054". I tried to modify the MIB-OID and I also tried the IP 127.0.0.1 which connection should never fail. I did not find any useable Tutorials about TIdSNMP at Google. :-(

How can I check the data transfer on a network interface in python?

由 大憨熊 提交于 2019-11-30 08:44:10
问题 There is a socket method for getting the IP of a given network interface: import socket import fcntl import struct def get_ip_address(ifname): s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) return socket.inet_ntoa(fcntl.ioctl( s.fileno(), 0x8915, # SIOCGIFADDR struct.pack('256s', ifname[:15]) )[20:24]) Which returns the following: >>> get_ip_address('lo') '127.0.0.1' >>> get_ip_address('eth0') '38.113.228.130' Is there a similar method to return the network transfer of that interface?
