信创下 net-snmp源码编译整理

---

前言

最近在项目上需要获取外设打印机相关节点信息，

---

一、源码地址

源码下载地址 http://www.net-snmp.org

二、依赖的数据源

sudo apt-get install cmake
sudo apt-get install libprel-dev

三、配置编译net-snmp

1. 解压 源码压缩包
2. cd  net-snmp-5.9.1
3.  ./configure --prefix=/usr/local/net-snmp --with-default-snmp-version=“2” --with-logfile=“/var/log/snmpd.log” --with-persistent-directory=“/var/net-snmp”
# configure 配置说明如下：
	#  --prefix=/usr/local/net-snmp  表示 net snmp的安装路径
	# --with-default-snmp-version=“2”表示 snmp版本
	# --with-logfile=“/var/log/snmpd.log” 表示日志文件路径
	#--with-persistent-directory=“/var/net-snmp”表示不变数据存储目录
5. make # 源码编译
6. make install # 安装
7. cd /usr/local/net-snmp/sbin 下执行 ./snmpd -v 输出版本信息。

四、snmpd.conf 配置

1. snmpd.conf是snmp服务的配置文件。
2. 将安装包路径下的 EXAMPLE.conf文件复制到 usr/local/net-snmp/share/snmp,并重命名为 snmpd.conf。
3. 下面为本人配置验证成功可以直接复制替换

#
# EXAMPLE.conf:
#   An example configuration file for configuring the Net-SNMP agent ('snmpd')
#   See the 'snmpd.conf(5)' man page for details
#
#  Some entries are deliberately commented out, and will need to be explicitly activated

#  AGENT BEHAVIOUR
#

#  Listen for connections from the local system only
#agentAddress  udp:127.0.0.1:161             #监听所有接入的网段
#  Listen for connections on all interfaces (both IPv4 *and* IPv6)
agentAddress udp:161,udp6:[::1]:161

#
#  SNMPv3 AUTHENTICATION
#
#  Note that these particular settings don't actually belong here.
#  They should be copied to the file /var/net-snmp/snmpd.conf
#     and the passwords changed, before being uncommented in that file *only*.
#  Then restart the agent

#  createUser authOnlyUser  MD5 "remember to change this password"
#  createUser authPrivUser  SHA "remember to change this one too"  DES
#  createUser internalUser  MD5 "this is only ever used internally, but still change the password"

#  If you also change the usernames (which might be sensible),
#  then remember to update the other occurances in this example config file to match.

#  It's no longer typically necessary to use the full 'com2sec/group/access' configuration

#  r[ou]user and r[ow]community, together with suitable views, should cover most requirements

#
#  Arbitrary extension commands
#
 extend    test1   /bin/echo  Hello, world!
 extend-sh test2   echo Hello, world! ; echo Hi there ; exit 35
#extend-sh test3   /bin/sh /tmp/shtest

#  Note that this last entry requires the script '/tmp/shtest' to be created first,
#    containing the same three shell commands, before the line is uncommented

#  Walk the NET-SNMP-EXTEND-MIB tables (nsExtendConfigTable, nsExtendOutput1Table
#     and nsExtendOutput2Table) to see the resulting output

#  Note that the "extend" directive supercedes the previous "exec" and "sh" directives
#  However, walking the UCD-SNMP-MIB::extTable should still returns the same output,
#     as well as the fuller results in the above tables.


#
#  "Pass-through" MIB extension command
#
#pass .1.3.6.1.4.1.8072.2.255  /bin/sh       PREFIX/local/passtest
#pass .1.3.6.1.4.1.8072.2.255  /usr/bin/perl PREFIX/local/passtest.pl

# Note that this requires one of the two 'passtest' scripts to be installed first,
#    before the appropriate line is uncommented.
# These scripts can be found in the 'local' directory of the source distribution,
#     and are not installed automatically.

#  Walk the NET-SNMP-PASS-MIB::netSnmpPassExamples subtree to see the resulting output
