# sshlog
|
|
A small tool to log IPs, usernames and passwords from incoming ssh-auth requests.
|
|
|
|
It opens a minimal SSH-Server and listens on IPv4 and IPv6 for auth requests.
|
|
The goal of this little tool is to log the requests coming from bots living inside the wild internet.
|
|
|
|
## Install
|
|
Make sure you have Golang installed and configured.
|
|
```shell
|
|
git clone https://git.sr.ht/~hamburghammer/sshlog
|
|
cd sshlog
|
|
go build
|
|
```
|
|
Now you should be able to execute the newly generated executable with `./sshlog`.
|
|
|
|
## Usage
|
|
Start with:
|
|
```shell
|
|
sshlog -p 2222
|
|
```
|
|
|
|
Output:
|
|
```text
|
|
2021/06/02 23:08:31 Starting ssh logger on port 2222...
|
|
2021/06/02 23:08:52 SRC=127.0.0.1 USERNAME=test PASSWORD=foo
|
|
2021/06/02 23:08:53 SRC=127.0.0.1 USERNAME=test PASSWORD=foof

|
2021/06/02 23:08:54 SRC=127.0.0.1 USERNAME=test PASSWORD=fooof
|
|
```
|
|
|
|
Output with `--json`:
|
|
```text
|
|

|
|
{"date": "2021-09-02T12:44:15+02:00", "src": "127.0.0.1", "username": "test", "password": "foo"}
