no permissions on tnsnames.ora

Hello Guys,

Have had a 9.2 client installed by a 3rd party on linux so pull some data of the linux box and squirt it into a remote oracle db. However I dont have permission to alter the tnsnames.ora file cos I dont have the oracle or root password.
[user_at_server02 admin]$ ls -l tnsnames.ora -rw-rw-r-- 1 oracle dba 337 Jun 3 13:36 tnsnames.ora So I cannot connect to the remote service. Or can I? Is there a workararound for connecting with sqlplus? Would it be normal to ask the hosting team to alter the client config as and when needed?
TIA Kevin
