    Hello:
          We have an IBM J45 with Aix 4.3.3 where we have SAP R/3 4.6C + Oracle
    8.0.6 ( develop machine ). I have been patching this AIX 'cause we need to
    upgrade Oracle to 8.1.7, and some AIX patches are required. Once the
    patches had been installed, with the necessary deps, and after rebooting
    the machine the net seems to not work. With smit, disconnecting and
    enabling en2 ( that's the interface linked to the LAN ) I can ping any
    machine in the LAN, any machine in the LAN can ping me, and can connect
    with telnet or other services, but the same AIX machine can't ping or
    connect to is own ip. Walking trougth smit menus and playing with some
    netstat commands, I can see that lo0 device ( loopback ) doesn't seems to
    exist, or at least, is not properly configured. For example: I can't see
    lo0 when netstat -ar reports the routing tables, I can't see lo0 when
    smit->Appl. communication services->TCP/IP->Advanced Conf.->Network
    Interfaces->Network interface controllers, but I can see it when
    smit->Appl. communication services->TCP/IP->Advanced Conf.->Network
    Interfaces->Network Interface Selec->List all network interfaces ( smit
    menus are translated on the fly from spanish ). For more info, here is the
    output of netstat -in

    Nom. Mtu Red Direcc. Ipkts Ierrs Opkts Oerrs Coll
    lo0* 16896 link#1 0 0 9 0

    en2 1500 link#3 0.4.ac.de.55.e8 19044 0 5540 0

    en2 1500 192.168.26 192.168.26.14 19044 0 5540 0

    Any tip?

    TIA, as always
