APAR status

  • Closed as program error.

Error description

  • When applying the "hls_ipsecpermit" (included in the
    High Security Level) and the HMC IP address is found,
    aixpert should allow all communications to/from HMC only,
    but due to an invalid filter mask, it let other IP source
    address full access to any opened port on VIOS.
    

Local fix

  • From oem_setup_env, use lsfilt to check HMC IP is set
    in rule 2 :
    # lsfilt -v 4 -n 2
    Rule 2:
    Rule action         : permit
    Source Address      : X.Y.Z.AAA  (HMC IP)
    Source Mask         : 0.0.0.0
    Destination Address : X.Y.Z.BBB  (VIOS IP)
    Destination Mask    : 255.255.255.255
     <== snip ==>
    
    Then you need to fix this, to do so, please run the
    following :
    # chfilt -v 4 -n 2 -m 255.255.255.255
    # mkfilt -v4 -u
