Re:_SMB_authentication…flakiness?

I'll take a look but am reluctant (read: lazy) to install a whole new thing
to do something that worked as recently as yesterday.

Seeing this on the client side:
Jul 10 18:15:18 <kern.crit> www kernel: smb_smb_negotiate: Don't know how
to talk with server xxx (65535)
I assume this was during the testing of smb v1, v1 + v2 and pure v2.

I did install samba on the client so I could use smbclient, hoping for more
debugging info.

smbclient -U www -I omphalos -N /tmp/mnt/storage  //mnt/storage
session setup failed: NT_STATUS_LOGON_FAILURE

and of course, now smbutil doesn't work as it used to.

The client on busybox allows some custom config to added: is there any
logging I can toggle on there?
