# Go Suricata Client
Gosuricata is a Go client library for interacting with suricata using the unix socket
## Prerequisites
* Go 1.12+ installed
* Suricata installed and running
* Suricata socket enabled in the suricata config along with the socket path
* See this [link](https://suricata.readthedocs.io/en/suricata-4.1.3/unix-socket.html#introduction) for enabling the socket
## Installation
Go get the library
```bash
go get github.com/ks2211/go-suricata
```
## Usage
```go
package main
import (
"github.com/ks2211/go-suricata/client"
"log"
)
func main() {
// create the client passing the path to the socket
// defaults are provided
s, err := client.NewSocket("/path/to/socket")
if err != nil {
log.Fatalf("Error conn %v", err)
}
defer s.Close()
// use the client to run command methods
commands, err := s.CommandListCommand()
if err != nil {
log.Fatalf("Error command list %v", err)
}
log.Println("COMMANDS", commands)
runningMode, err := s.RunningModeCommand()
if err != nil {
log.Fatalf("error running mode %v", err)
}
log.Println("RUN MODE", runningMode)
// run a command manually--note you will have to pass in a struct/map/interface
// the type can be marshalled into json
r, err := s.DoCommand("some-command", struct{
Field string `json:"field"`
}{
"test"
})
if err != nil {
log.Fatalf("error running command %v", err)
}
// handle response
retData := map[string]interface{} // or struct
if err := json.Unmarshal(r.Message, &retData); err != nil {
log.Fatalf("error unmarshal data %v", err)
}
log.Println("response", r.Status, retData)
}
```
## Design
The way the library/client is set up:
* The socket client holds a net.Conn with base methods to send/receive messages from the socket
* All v3, v4, and v5 commands are methods of the Socket client. You create 1 client regardless of version, commands not available in a specific version will return an error
* E.g If you are running Suricata v3 but attempt to use the hostbit or memcap commands, they will return an error
* The clients implements most (if not all) commands for that specific Suricata version. The command methods that are not implemented by the library, the user has the option of using the `DoCommand` method to run the command manually.
* Each command returns a JSON response (shown below) with a status and a "message" that is either a JSON object or a string with the response from the command
```json
{
"status": "OK|NOK",
"message": {}|""
}
```
* For implemented methods, the library will parse the message into Go types (either string for string messages or a Go struct for json message)
* For unimplemented methods, the `message` field will be converted to Go's `json.RawMessage`. A user can unmarshal this field into their own Go type.
```go
resp, err := s.DoCommand("command-list", nil)
if err != nil {
// handle err
}
fmt.Println(string(resp.Message)) // prints string of json
response := struct{
FieldA string `json:"field_a"`
}{}
if err := json.Unmarshal(resp.Message, &response); err != nil {
// handle err
}
// work with the response
```

## Testing
*IN PROGRESS*
* In order to run tests, you will need to either run them as sudo/root or have access to the suricata socket
* To run tests, run `go test`. You can pass in the `-run=` flag to run a specific test
* The tests for the base client relies on Suricata Version 3.2
* *TODO*: Most of the test case expected values (e.g interface names, suricata config items) have been hardcoded to my personal machine
* *TODO*: There is a lot of duplicate/repeated code around creating the socket client/closing the connection for each testing method--need test helpers
* *TODO*: Mock the interface for testing
## TODO
* Testing (In progress)
* Tenant commands in V3
* DumpCounters in V3 has a large response, figure out how to handle that
* V4 memcap commands-validate setmampcap
* V5 Commands
* PCAP command support
* General cleanup (idomatic patterns, gofmt, lint, etc)
* Look into codegen since a lot of repeated/duplicate code
