Unfortunately, not at the moment. There should be some working python code somewhere (wiki?) -- I had some working as well at one point a while back. For now, I can use
(edited)bx, which always works for me, but sometimes when it works for me, I am told it's not externally available and I don't know why, but I'm chalking it up to my router being strangeneillm02:39
Ok, nevermind, I ran it just now:

Oh, hell yeah, thanks! Yeah the wiki example was the one I tried that didn't work. I'll give this a whirl!

Can you reach the server's port 9091 (e.g. telnet)? That exact code is working for me using both python2 and python3, so I don't think the version is the issue

Hrm, I'm not sure then. I have had people report connectivity problems to this server in particular in the past even when it was up/responsive to me. Until I can get things moved to another server, I'm not sure what else to try at the moment
