    I have been working with a DBA on trying to get the listener started, he runs into a error when starting and it points back to loopback interface. here is my output from and ifconfig -a (AIX 5.3):

    en0: flags=1e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
    inet * netmask 0xffffff00 broadcast *
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
    lo0: flags=e08080a<BROADCAST,LOOPBACK,SIMPLEX,MULTICAST,GROUPRT,64BIT>

    As you can see there is no loopback. I need to turn it back on, I can't ping localhost and the 127.0.0.1 localhost is in /etc/hosts. This is from another server successfully running loopback.

    en0: flags=1e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
    inet * netmask 0xffffff00 broadcast *
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
    en1: flags=1e080822,480<BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),CHAIN>
    lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT>
    inet 127.0.0.1 netmask 0xff000000 broadcast *

    Please help me!! Thanks in advance.
