Thanks Toralf. Took a quick peek but this is gonna require more thought. Tor's IPv6 addrspec states that policies should have brackets...

... but the torrc is looser...

Stem accounts for this by adding brackets when reading from a torrc file, but requiring them from other spots through the control port. So question is 'how is nyx fetching this?'. If its coming from certain control port commands then this is a tor bug, whereas with other spots it's a stem or nyx bug.

Regardless, please file a ticket for this with actual torrc lines that reproduce the issue...

Hi atagar,

    ./run_nyx

gives an empty

    exit policy:

line in that case - is this bug or a feature?

:-)

Example for a wrong line:

    ExitPolicy reject6 <snip>/32

Good is

    ExitPolicy reject6 [<snip>]/32

Tested with latest stem and nyx Git trees.
