    Hi,

    We have a customer with several agents running fine. We installed a brand new autosys agent and we get this error on receiver.log

    Telnet in both direction works fine but autoping fails.
    Agent configuration seems to be fine to me.

    have you ever seen this error?
    It seems to me like it is receiving larger packets than expected but not sure why.

    thanks
    José

    Hi Jose,

    Could it be a port scanner checking the machine?  I'd assume the other agents would get the same thing unless they are excluded from the scan.

    Regards,
    Mike
