我正在尝试使用 SNMP 终止进程。我知道可以将进程的“状态”字段设置为 4，例如：

snmpset -v 2c -c community_string ipaddress 1.3.6.1.2.1.25.4.2.1.7.PID i 4

我总是收到同样的信息：

数据包错误。原因：不可写（该对象不支持修改） 失败对象：iso.3.6.1.2.1.25.4.2.1.7.PID

我不知道为什么，但是当我使用通常具有所有权限的“localhost”时也会发生这种情况。也许我的设置有问题？这是我的 snmpd.conf 文件：

#  AGENT BEHAVIOUR
#

#  Listen for connections from the local system only
agentAddress  udp:161
#  Listen for connections on all interfaces (both IPv4 *and* IPv6)
#agentAddress udp:161,udp6:[::1]:161

上面的这条消息可能就是它所说的。该变量是只读的，不能编辑。MIB 中指定变量是否可写。你最好先检查 MIB。如果一个变量是只读的，那么你做什么都没关系。

据我所知，使用 SNMP 杀死进程并不常见。至少你通常不会那样做。SNMP 用于管理网络。但是如果你有一个专有的 MIB，你必须检查它，看看它在那里说了什么。
