    Hello,
    I had capability to ssh into the cs551 account of the machined
    aludra.usc.edu (I am the TA!). I am not exactly sure what changed, but
    I am no longer able to access the account, even thought the prof.
    having access to tha account has verified that my public key is in the
    authorized_keys of the account. So I tried the verbose output and it
    seems that in the final lines of the verbose output by ssh below(before
    it asks me for the cs551 accoutn pwd .. which i dont have) It *tries*
    (no what does that mean) two keys that arent in my .ssh account at all.
    Then if offers the id_dsa key (I would have thought that it would offer
    the id_dsa.pub key?) which i do have (and whose pub key is in the
    aco***!!!) but it still seems to fail and ask for password!!! Any
    suggestion/tips on what might be wrong?
