Is this because there is already a listener on that port?

If there is already a listener it shouldnt work... I'll look at it

I wrote a quick fix for it but I'm not sure it will work for you - its been working fine for me.

Still doesn't work - I think it has to do with how we're giving root privilege to the shell we're spawning?
Try running it against the target box

Your previous error appears to be what we were getting when the poison module was broken... does it still not work for you?
