client connect to 10g instance

client connect to 10g instance

Is this right or has something changed in 10g (10.1.0.3.0).  This is on
RHEL4 x86_64.

I am consisting getting an:

ora-12535 (See ora-12535.ora-code.com) tns: operation timed out

when trying to connect from my client windows machine to the Linux server
with 10g Ent ed.

I can perform a loopback with no problem.

See the result of the adapters command and the ldd command:
