are Plan9-1 and Plan9-2 in different authentication domains? if they
are not, this could explain fact 4. you would have two auth servers serving
the same authentication domain. this would explain how cpu could work
when a direct login does not if you also have trouble contacting the remote
authentication server but not the local one. this would allow plan 9 to know
about the local auth server when drawterm may not.
the long timeouts are sound like dns lookup problems to me. i generally
double-check my ndb entries in cases like this, especially the auth, ip, and
ipnet entries associated with the auth server.
