Setup seems right but still TNS-12535: TNS:operation timed out
I have Oracle express Edition installed on Fedora 4. I know the listener is started and believe the tnsnames.ora is configured properly but still get a timout when I try to connect with SQL*Plus. I am able to get into SQL with tue GUI tools but want to be able to get into SQL*Plus so I can refresh my skills with writing shell scripts. The only thing I can think is that some port is blocked somewho. I get this timeout when I start a terminal session directly on the computer. I think my environment variables are correct or I would get a different error.
