ubuntu 20.04 snmp 配置 agentx
设置 ubuntu 20.04 静态IP地址
sudo vi /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
ethernets:
ens33:
dhcp4: no
addresses: [192.168.99.32/24] # 修改成自己的IP地址
optional: true
gateway4: 192.168.99.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
version: 2
renderer: NetworkManager
应用配置
sudo netplan apply
使用ip addr检查新地址
ip addr
安装 ssh服务
sudo apt install openssh-server
sudo ufw status
sudo vi /etc/ssh/sshd_config
#/etc/ssh/sshd_config
#其它根据个人需要进行修改，本文只介绍最基本的ssh配置
#Port 22 #ssh的端口设置，建议修改，可以避免端口扫描
Port 22222 #建议修改为5位数的端口，此处作为示例
#PermitRootLogin prohibit-password
PermitRootLogin no #禁止使用root用户连接
sudo systemctl restart sshd
安装 snmpd
sudo apt-get install snmpd snmp
验证
snmpwalk --help
查看端口访问情况
sudo netstat -antup | grep 161
修改/etc/snmp/snmpd.conf配置文件，大概在15行，将下面一行注释掉：
agentAddress udp:127.0.0.1:161
同时去掉下面这一行的注释：
#agentAddress udp:161,udp6:[::1]:161
重启snmpd 服务
sudo service snmpd status
sudo service snmpd restart
命令snmpwalk
snmpwalk -v 2c -c public localhost 1.3.6.1.2.1.1.1
mibs配置文件位置
/usr/share/snmp/mibs
配置文件
sudo vi /etc/snmp/snmpd.conf
python agentx
sudo curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2 get-pip.py
sudo pip install pyagentx
sudo pip install redis
https://github.com/hosthvo/pyagentx
sudo apt install snmp-mibs-downloader
如果 /usr/share/snmp/mibs 里面的文件不全，需要执行上面的命令

# snmpd.conf
# An example configuration file for configuring the Net-SNMP agent ('snmpd')
# See snmpd.conf(5) man page for details
#
###########################################################################
# SECTION: System Information Setup
#
# syslocation: The [typically physical] location of the system.
# Note that setting this value here means that when trying to
# perform an snmp SET operation to the sysLocation.0 variable will make
# the agent return the "notWritable" error code. IE, including
# this token in the snmpd.conf file will disable write access to
# the variable.
# arguments: location_string
sysLocation Sitting on the Dock of the Bay
sysContact Me <me@example.org>
# sysservices: The proper value for the sysServices object.
# arguments: sysservices_number
sysServices 72
###########################################################################
# SECTION: Agent Operating Mode
#
# This section defines how the agent will operate when it
# is running.
# master: Should the agent operate as a master agent or not.
# Currently, the only supported master agent type for this token
# is "agentx".
#
# arguments: (on|yes|agentx|all|off|no)
master agentx
#agentxSocket tcp:localhost:705
#agentxTimeout 5000
#agentxRetries 0
# agentaddress: The IP address and port number that the agent will listen on.
# By default the agent listens to any and all traffic from any
# interface on the default SNMP port (161). This allows you to
# specify which address, interface, transport type and port(s) that you
# want the agent to listen on. Multiple definitions of this token
# are concatenated together (using ':'s).
# arguments: [transport:]port[@interface/address],...
#agentaddress 127.0.0.1,[::1]
agentAddress udp:161

# SECTION: Access Control Setup

# This section defines who is allowed to talk to your running
# snmp agent.
