In regards to the thought on TCP, this is from the OP:

test1- sqlplus '/as sysdba'
test2- sqlplus scott/tiger
test3- sqlplus scott/tiger_at_tnsname

It would appear that these login attempts are taking place on the server.

If that is the case, is this connection via TCP, or IPC?

Doing a tnsping from the box you are testing on will show that.

Is this the same box the user was trying to connect from?

Also, as you are on solaris, have you done a truss on the the sqlplus session?

That would show what is happening when the connection appears to hang.
