Re: [tor-talk] Fixing Orchid (again), need help!

[Masayuki Hatta <mhatta@xxxxxxxxx>]

Hi,

Some follow-up on fixing Orchid.

AFAIK Orchid connects one of dir auths and sends a (variable length)
VERSIONS cell, which seems to be correct.  After a while, the
connection to the dir auth is closed and gets:

2018-11-18 14:55:18,919 DEBUG - ConnectionImpl - Closing connection to !bastet!
connectionControlCells.take = Cell: circuit_id=0 command=0 payload_len=3

I think command=0 is weird (padding?), but I don't know what is
supposed to be.  Appreciate any hints.

Best regards,
MH
