tnsping works fine but lsnrctl and sqlplus gives error from remote server

Hi,

When using tnsping from a remote server, i get a proper response, but lsnrctl and sqlplus gives error.

LSNRCTL gives:-

TNS-01189: The listener could not authenticate the user

and when trying to connect to the instance through sqlplus i get :-

ORA-12505: TNS:listener does not currently know of SID given in connect

descriptor

I am using :-

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

PL/SQL Release 11.2.0.3.0 - Production

CORE    11.2.0.3.0      Production

TNS for Solaris: Version 11.2.0.3.0 - Production

NLSRTL Version 11.2.0.3.0 - Production

ON Sparc(SunOs 11)

I tried to ssh from the source to target server and it works fine.
