Does the hostname it has bound to actually resolve to the IP address you are using (on both client and server)?
What is the result (with actual error code) when you connect using SQL Developer without TNS, but just entering hostname, port and service name/sid for your XE instance?I get the same thing as I get with TNS "Status: Failure-Test failed: IO Error: The Network Adapter could not establish the connection" even if I put 192.168.1.135 in the hostname section of SQL Developer or brandon-Linux
So I went back in to the iptables file and it is still clear of any rules.This means nothing and doesn't mean connections are allowed.
