Error starting userland proxy: listen tcp4 127.0.0.1:22: bind: address already in use.

After doing the following:

git clone https://github.com/DominicBreuker/stego-toolkit.git
cd ./stego-toolkit/bin
./build.sh
# No indicate of errors in above script.
./run.sh

... I get:

sysadmin@UbuntuDesktop:~/git/stego-toolkit/bin$ ./run.sh 
Starting container now...
docker: Error response from daemon: driver failed programming external connectivity on endpoint keen_dewdney (e3af358b8bb3f91315ba38d3224f257afd43721ba8284d20bc4fcf98567bfe27): Error starting userland proxy: listen tcp4 127.0.0.1:22: bind: address already in use.

Yes, I'm running sshd locally. No, I don't want to stop it or change the port. I want to know which file needs to be edited for the docker container sshd to listen on another port.
