    Networking isssues

    Connecting from client(unix) to virtual server (NT).

    Checked with firewall team and amended the hosts file. I can ping the server from the client.

    Can't tnsping or sqlplus via the link. I've double checked the settings

    Any ideas?



    Client

    tnsnames.ora

    UTOUAT1 =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = uatbckuto01)(PORT = 1521))
    )
    (CONNECT_DATA =
    (SERVICE_NAME = UTOUAT1)

    sqlnet.ora

    NAMES.DIRECTORY_PATH = (TNSNAMES, ONAMES, HOSTNAME)
    names.default_domain=world
    names.default_zone=world

    Server

    hosts file is correct


    Looks like a firewall/NAT issue as its not resolving the correct IP address????
