GoSNMPServer is an SNMP server library fully written in Go. It provides Server Get,
GetNext, GetBulk, Walk, BulkWalk, Set and Traps. It supports IPv4 and
IPv6, using __SNMPv2c__ or __SNMPv3__. Builds are tested against
linux/amd64 and linux/386.
TL;DR
-----
Build your own SNMP Server, try this:
```shell
go install github.com/slayercat/GoSNMPServer/cmd/gosnmpserver
$(go env GOPATH)/bin/gosnmpserver run-server
snmpwalk -v 3 -l authPriv -n public -u testuser -a md5 -A testauth -x des -X testpriv 127.0.0.1:1161 1
```
Quick Start
-----
```golang
import "github.com/gosnmp/gosnmp"
import "github.com/slayercat/GoSNMPServer"
import "github.com/slayercat/GoSNMPServer/mibImps"
```
```golang
master := GoSNMPServer.MasterAgent{
Logger: GoSNMPServer.NewDefaultLogger(),
SecurityConfig: GoSNMPServer.SecurityConfig{
AuthoritativeEngineBoots: 1,
Users: []gosnmp.UsmSecurityParameters{
{
UserName: c.String("v3Username"),
AuthenticationProtocol: gosnmp.MD5,
PrivacyProtocol: gosnmp.DES,
AuthenticationPassphrase: c.String("v3AuthenticationPassphrase"),
PrivacyPassphrase: c.String("v3PrivacyPassphrase"),
},
},
},
SubAgents: []*GoSNMPServer.SubAgent{
{
CommunityIDs: []string{c.String("community")},
OIDs: mibImps.All(),
},
},
}
server := GoSNMPServer.NewSNMPServer(master)
err := server.ListenUDP("udp", "127.0.0.1:1161")
if err != nil {
logger.Errorf("Error in listen: %+v", err)
}
server.ServeForever()
```
Serve your own oids
-----
This library provides some common oid for use. See [mibImps](https://github.com/slayercat/GoSNMPServer/tree/master/mibImps) for code, See [](https://godoc.org/github.com/slayercat/GoSNMPServer/mibImps) here.
Append `GoSNMPServer.PDUValueControlItem` to your SubAgent OIDS:
```golang
{
OID: fmt.Sprintf("1.3.6.1.2.1.2.2.1.1.%d", ifIndex),
Type: gosnmp.Integer,
OnGet: func() (value interface{}, err error) { return GoSNMPServer.Asn1IntegerWrap(ifIndex), nil },
Document: "ifIndex",
},
```
Supports Types: See RFC-2578 FOR SMI
- Integer
- OctetString
- ObjectIdentifier
- IPAddress
- Counter32
- Gauge32
- TimeTicks
- Counter64
- Uinteger32
- OpaqueFloat
- OpaqueDouble
Could use wrap function for detect type error. See `GoSNMPServer.Asn1IntegerWrap` / `GoSNMPServer.Asn1IntegerUnwrap` and so on.

This library is based on **[soniah/gosnmp](https://github.com/soniah/gosnmp)** for encoder / decoders.
