[tor-relays] OBFS4 Bridge

[pvr6 at sigaint.org]

Have been running an obfs3 bridge for a while. Since I was building a new
Debian server wanted to add obfs4, but when I configure TBB to point to
the obfs4 port [Z] I get "general SOCKS failure" in the TBB log. Changing
it back to use obfs3 and port [Y] works fine. How can I fix it so obfs4
works too?

Here are the relevant lines from torrc:
---
ORPort [X]

BridgeRelay 1
PublishServerDescriptor bridge

ServerTransportPlugin obfs3 exec /usr/bin/obfs4proxy managed
ServerTransportListenAddr obfs3 0.0.0.0:[Y]
ServerTransportListenAddr obfs4 0.0.0.0:[Z]
ExtORPort auto
---

If I do netstat -pan, I see obfs4proxy is listening on both ports on all
interfaces. I tried to add "--log-file logfile" after /usr/bin/obfs4proxy
in torrc but then it wouldn't start the proxy at all. I'm not finding any
other log messages showing a problem. Tor's log is clean, just shows it
starting both proxy instances (which netstat confirms.) Obfs4proxy is the
packaged version 0.0.6.

Not sure where else to look or change. I'd like to get it working but have
commented out the obfs4 line for now.
