  • 1.  Ping itself take long time...all the local IP addresses

    Customer has a System p server w/ AIX 5.3 TL08 installed and with some IP addresses configured on some interfaces.
    That machine can ping to other machine (icld. gateway) and can be pinged from the others without any problem (time < 5ms).
    But when ping itself by IP addresses, including the 127.0.0.1 and other IP, the time take too long (time = 4000ms)

    The resuls is smth like: ping 127.0.0.1 => ... time = 4000ms
    ping 10.0.91.64 => ... time = 3189ms (local IP on other interface)
    ping 10.0.91.79 => ... time = 2000ms (local IP on other interface)
    .........

    Did anyone experience this?

    Tks in adv.

    never saw this, but first thing to check should be routing.
    as root: route get <destination>
    then investigate the routing table but be aware that aix unlike other unixes adds broadcast routes and interface routes for every ip configured, as well as cloned routes if PMTU discovery is turned on.

    Thank you, I'll look more but there should be no prob w/ routing table since we all have only 1 default route configured on the en0 interface (on all srvs).
    Will update if there are more inputs.

    Can you post the output of,

    ifconfig -a
    netstat -rn
    cat /etc/resolv.conf

    Is this server a server, an LPAR, a WPAR, an LPAR running with VIOS resources?
