[9fans] rx problem on cpu/auth standalone machine

[Moroo Jun <moroo@nifty.com>]

My plan9 box(named tp560x) is a standalone cpu/auth server.
After updating Plan9, upas cron left error logs on /sys/log/cron as 
follows.

tp560x Jan 12 10:01:15 upas: can't call tp560x: connection refused

So I cheked rx command logged in as upas.

tp560x# rx tp560x ls
rx: auth_proxy: auth_proxy rpc write: bootes: bad key

/sys/log/auth logged as follows.
tp560x Jan 12 02:31:07 tr-fail upas@bootes(192.168.1.32) -> upas@bootes 
no speaks for
tp560x Jan 12 02:31:07 tr-ok upas@bootes(192.168.1.32) -> upas@bootes

At this time, /mnt/factotum/log says,
cpu% cat /mnt/factotum/log
13: no key matches proto=p9sk1 role=server dom?
13: failure no key matches proto=p9sk1 role=server dom?
12: failure upas can't use bootes's keys
12: failure bad key

I reset password and users likes as Plan9 Wiki page.

But no luck.

Cron commands by bootes and rx commad from bootes works fine.

Where should I check?

Thank you.
