I connect to Oracle from server successfully. but from client give me an error
Error in .oci.Connect(...) : ORA-12569: TNS:packet checksum failure
what do I do?
Have you tried any of the suggestions? Can you connect on the client via <tt>sqlplus</tt> using <tt>sqlplus user/pass@db</tt>? If yes then <tt>ore.connect("user", password = "pass", conn_string = "db")</tt> should also work. If <tt>sqlplus</tt> works while <tt>ore.connect</tt> still does not, please, paste both the <tt>sqlplus</tt> and <tt>ore.connect</tt> sessions and I'll try to troubleshoot.
