I don't think that there is a bug in this code path. You need Gtk >=
3.14 (basically Jessie). Please clone the repository again as I messed
up the initial commit.

The user running tormonitor must have access to Tor control socket
*and* to Tor SOCKS port. In Tails/Jessie:

    sudo iptables -I OUTPUT 1 -p tcp --dport 9050 -d 127.0.0.1 -m owner
        \ --uid-owner vidalia -j ACCEPT
    sudo -u vidalia tormonitor

Tor Monitor provides this info.

Tor Monitor doesn't provide this feature yet. It would be very easy to
add, even though I'm not sure I find it desirable: currently we only
*monitor* Tor. Do we also really want to *control* it?

That would be quite easy to add it there is a consensus that it is
useful.

Easy to add, even though I'm not convinced for the same reason as

It would be possible (and I think desirable) to add a bandwidth graph to
Tor Monitor and I already thought about it. But I don't know how to
implement that in Gtk yet, and I'd better see this as a fun item than
as a required feature. Patches are welcome though, and if there is a
consensus that it is required I'll do it.

I agree on that. Currently Tor Monitor provides circuit and associated
streams, and infos on relays in a circuit. We could add the logs easily
and the bandwidth graph less easily to provide a nice monitor. I'm not
sure that the other features are desirable.
