net-snmp

I am developing a Net-SNMP subagent whose final target will be an ARM board, so I'm using CMake to make it easier to manage building the native and cross-compiled versions. I started testing it on my host platform (x86_64) and it builds and works fine with this CMakeLists.txt file: cmake_minimum_required (VERSION 2.6) project (snmp_agent C) set(snmp_agent_VERSION_MAJOR 1) set(snmp_agent_VERSION_MINOR 0) # Defines path to the net-snmp-config script set(NETSNMPCONFIG "${CMAKE_FIND_ROOT_PATH}/usr/bin/net-snmp-config") # Gets compiling flags and libs linked to Net-SNMP execute_process(COMMAND "$

I'm working on traps using NET-SNMP and the DISMAN Event MIB With the following snmpd.conf configuration: createUser disman MD5 sercrt@1 rouser disman auth agentSecName disman #defaultMonitors yes disk / 90% disk /var 85% disk /opt 95% disk /opt/pkgs 90% disk /ufda 90% proc cron proc rtrcopy 1 1 proc socks1081 1 1 # monitor must have ".." in the line monitor -u disman -r 30 -o prNames.1 -o prErrMessage.1 "Cron not running" prErrorFlag.1 != 0 monitor -u disman -r 30 -o prNames.2 -o prErrMessage.2 "rtrcopy running" prErrorFlag.2 != 0 monitor -u disman -r 30 -o prNames.3 -o prErrMessage.3

Is it possible to programatically change an executable name (ucmd) of a unix process as reported by ps? unix/POSIX way would be nice but Linux specific solution would suffice. I want to change what is reported here > ps -o ucmd CMD zsh ps not this, this I know ;) > ps -o command COMMAND zsh ps -o command thanks P.S. Not trying to create a rootkit, its just that net-snmp looks at this name when checking processes and my program has a different name when called from init and directly from /etc/init.d (etc/rcX.d/SNNname instead of just name). You can do this with the PR_SET_NAME function of prctl

The network device has been configured with snmpv3 users which uses AES192 as the privacy protocol.But when the following command is executed snmpwalk -v3 -l authPriv -u user -a SHA -A authpass -x AES256 -X privpass device_ip:161 oid It throws the following error Invalid privacy protocol specified after -x flag: AES256 but when i tried using AES128 encryption the snmpwalk worked perfectly fine,which made me think if AES192&256 features are supported if not why was it not included. The original SNMP RFC documents do not require those. Thus, along with other reasons Net-SNMP never supports them,

I am using net-snmp version 5.7.3 I implemented the following code into the net-snmp/agent/mibgroup directory: #include <net-snmp/net-snmp-config.h> #include <net-snmp/net-snmp-includes.h> #include <net-snmp/agent/net-snmp-agent-includes.h> #include

案例1：部署Cacti监控平台 案例2：构建Cacti监测系统 1 案例1：部署Cacti监控平台 1.1 问题 本案例要求部署一台Cacti监控主机，并安装相关监控组件，为进一步执行具体的监控任务做准备： 安装net-snmp、net-snmp-utils 安装LAMP及相关依赖软件包 部署Cacti监控平台 初始化监控页面 1.2 方案 使用1台RHEL7虚拟机，安装部署LAMP环境、Cacti及相关的snmp组件包，配置数据库并对Cacti监控平台进行初始化操作。 1.3 步骤 实现此案例需要按照如下步骤进行。 步骤一：准备基础软件包 1）安装LAMP环境 Cacti监控需要通过Web页面展示出来，并且还需要使用MySQL来存储一些变量数据，因此需要先为Cacti准备基础LAMP环境。因为Cacti监控其他主机数据时使用的是snmp协议，所以还需要安装net-snmp和net-snmp-utils软件包。 [root@svr5 ~]# yum -y install httpd php php-mysql php-ldap >php-xml mysql mysql-server net-snmp net-snmp-utils lm_sensors [root@svr5 ~]# service httpd start;chkconfig httpd on //启动httpd服务

Linux安装snmp详解 Snmp一种网络之间的传输协议，通过snmp可以采集很多指标比如cpu、内存及磁盘的信息，现在越来越多的网络设备基本上都支持snmp，本文介绍了snmp的安装过程。 二、安工具/原料 SecureCrt Xftp 三、安方法/步骤 l 从网上下载snmp的相关tar包，然后上传到服务器中，然后解压安装包，执行如下命令：tar -zxvf net-snmp-5.7.2.1.tar.gz l 修改解压后的文件名称，默认解压后的文件名称为tar包前面的内容。执行命令：mv net-snmp-5.7.2.1 net-snmp l 然后进入net-snmp的目录，执行下面的命令：./configure --prefix=/usr/local/net-snmp --with-default-snmp-version="2" --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp" --with-mib-modules="ucd-snmp/diskio" l 输入该命令后，会有一个交互的过程，所有的交互直接回车即可。configure运行完成后，执行make指令。 l make命令执行完毕后，记得切换到root用户执行命令make install，进行安装
