Hi,

I configured successfully an introducer node on a debian box. Now I want to configure a client on my OSX box. So I've done :

% tahoe create-client
then ~/.tahoe got created
% tahoe start
then it outputs :

STARTING /Users/guyzmo/.tahoe
/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/twisted/persisted/sob.py:12: DeprecationWarning: the md5 module is deprecated; use hashlib instead

  import sha
Removing stale pidfile /Users/guyzmo/.tahoe/twistd.pid
client node probably started

I'm running :

And the log twistd.log is joined with the ticket.

Just a hint : it fails with en6 in the error log, and en6 has been created by PDAnet to do mobile network tethering.

Thanks for the bug report. I don't recognize this and I'm just guessing, but could you try upgrading to the latest release of Twisted? It shows there that you are using Twisted 8.2.0. The current release is Twisted 10.0.0. Thanks!

Just a hint : it fails with en6 in the error log, and en6 has been created by vmware-fusion to connect to virtual machines (but it's not running).

well, after some investigations, it has not been created by vmware fusion, it's been created by PDAnet, a tool that does mobile phone tethering through USB... basically it's like a point-to-point tun interface, so I shall report the bug to them. Meanwhile, I'm gonna try to find out if I can't work out a patch to just catch that exception and make it ignore it (as that network interface is not meant to be used by tahoe-lafs)

Just so people don't have to click through to the twistd.log to see, here is the fatal error:

The only way I got around this bug is to launch PDAnet while lauching tahoe.

If someone can tell me how can I get full tracebacks in the twistd.log when launching tahoe, I may write a patch that ignores that kind of errors (as all is needed is to have at least one interface working, not all interfaces)... having it around may be useful for a future user that gets into the same kind of troubles I went into.

Replying to guyzmo:

What do you mean? Launching PDAnet while launching Tahoe-LAFS causes this bug to occur? Or does it cause this bug to stop occurring?

guyzmo: on your system, in the configuration that previously failed, does the command ip addr appear to work?

guyzmo, please try to reproduce this with current Tahoe-LAFS trunk.

Note that as a side-effect of the fix to #754 (which will be released in Tahoe-LAFS 1.10.1), setting tub.location without including "AUTO" will skip the local IP auto-detection code entirely, thus allowing a workaround for this problem if the other changes on trunk didn't fix it.
