Now I'm trying to get https://twistedmatrix.com/documents/current/_downloads/9620a18fe21cabe0de79cc9c0efe1043/sshsimpleserver.py running locally. To do so it says I need to first do "ckeygen -t rsa -f ssh-keys/ssh_host_rsa_key". ssh-keygen is a command that's commonly available on Linux systems but ckeygen...  that appears to be a twisted thing. When I try to run that on Ubuntu I get a "-bash: ckeygen: command not found" error.

Maybe there's a ckeygen.py file that I need to be running but if so idk where it is. Maybe if I did I could rename it to ckeygen and then copy it to /usr/bin or whatever and run it from there but idk.

Thanks!
