RUST-SNMP

纯 Rust 的 SNMPv2 客户端库，无需依赖。

支持

• GET
• GETNEXT
• GETBULK
• SET
• 基本的 SNMPv2 类型
• 同步请求
• UDP 传输

目前不支持

• SNMPv1
• SNMPv3
• MIBs
• 异步请求
• 除 UDP 以外的传输

待办事项

• 异步请求
• 遍历功能
• 额外的 ObjectIdentifier 工具方法
• 解耦 PDU 构建/解析与套接字处理
• SNMPv3（需要外部依赖）

示例

GET NEXT

use std::time::Duration;
use snmp::{SyncSession, Value};

let sys_descr_oid = &[1,3,6,1,2,1,1,1,];
let agent_addr    = "198.51.100.123:161";
let community     = b"f00b4r";
let timeout       = Duration::from_secs(2);

let mut sess = SyncSession::new(agent_addr, community, Some(timeout), 0).unwrap();
let mut response = sess.getnext(sys_descr_oid).unwrap();
if let Some((_oid, Value::OctetString(sys_descr))) = response.varbinds.next() {
    println!("myrouter sysDescr: {}", String::from_utf8_lossy(sys_descr));
}

GET BULK

use std::time::Duration;
use snmp::SyncSession;

let system_oid      = &[1,3,6,1,2,1,1,];
let agent_addr      = "[2001:db8:f00:b413::abc]:161";
let community       = b"f00b4r";
let timeout         = Duration::from_secs(2);
let non_repeaters   = 0;
let max_repetitions = 7; // number of items in "system" OID

let mut sess = SyncSession::new(agent_addr, community, Some(timeout), 0).unwrap();
let response = sess.getbulk(&[system_oid], non_repeaters, max_repetitions).unwrap();

for (name, val) in response.varbinds {
    println!("{} => {:?}", name, val);
}

SET

use std::time::Duration;
use snmp::{SyncSession, Value};

let syscontact_oid  = &[1,3,6,1,2,1,1,4,0];
let contact         = Value::OctetString(b"Thomas A. Anderson");
let agent_addr      = "[2001:db8:f00:b413::abc]:161";
let community       = b"f00b4r";
let timeout         = Duration::from_secs(2);

let mut sess = SyncSession::new(agent_addr, community, Some(timeout), 0).unwrap();
let response = sess.set(&[(syscontact_oid, contact)]).unwrap();

assert_eq!(response.error_status, snmp::snmp::ERRSTATUS_NOERROR);
for (name, val) in response.varbinds {
    println!("{} => {:?}", name, val);
}
