# sshlowpot
Yet another no-frills low-interaction ssh honeypot in Go.
Accepts SSH connections on a given port (2222 by default), records
authentication attempts and tells the connecting client the authentication
failed.
**Please note that this is not yet production code. In particular, the log
output is subject to change.**
## Installation
Get and build the source:
```bash
go get github.com/magisterquis/sshlowpot
go install github.com/magisterquis/sshlowpot
```
Compiled binaries can be made available upon request.
Make sure IP forwarding is enabled and forward the port. The following
examples assume the external-facing port is 22 and sshlowpot is listening on
2222.
OpenBSD:
```bash
#Assuming the external-facing interface is vio0
[root@box]# sysctl net.inet.ip.forwarding=1
[root@box]# echo "pass in on vio0 from any to (vio0) port 22 rdr-to 127.0.0.1 port 2222" >> /etc/pf.conf
[root@box]# pfctl -vf /etc/pf.conf
[user@box]$ sshlowopt -v
```
Linux:
```bash
[root@box]# sysctl net.ipv4.ip_forward=1
[root@box]# iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 22 -j REDIRECT --to-port 2222
[user@box]$ sshlowpot -v
```
## Usage
```
Usage: sshlowpot [options]
Options are:
-a address
Listen address (default "127.0.0.1:2222")
-key file
SSH private key file, which will be created if it doesn't already exist (default "slp_id_rsa")
-to timeout
SSH handshake timeout (default 1m0s)
-v Enable verbose logging
-ver version
SSH server version string (default "SSH-2.0-OpenSSH_7.0")
```
For the most part, no options are required as long as you can forward your
external port of choice to 127.0.0.1:2222. Please don't run it as root on 22.
## Output
Output should look something like the following (with `-v`):
