            0509-130 Symbol resolution failed for sshd because:
            0509-136   Symbol __stack_chk_fail (number 230) is not exported from

    Old version of libc library? I'm not sure if the latest SSL is compatible with ancient AIX 6.1...

    Hi Igor

    i followed instruction from this link

    https://www.ibm.com/support/pages/downloading-and-installing-or-upgrading-openssl-and-openssh.

    and it seems that OpenSSL 1.1.1 supported for AIX 6.1

    Probably you have a older AIX 6.1 TL level 
    What is the output of "oslevel -s" ?

    It's just old TL03 without any SP...

    Go to IBM Fixcentral, download 6100-09-00-1391 and 6100-09-12-1864 packages.

    Apply the first one (TL09), then the second (SP12).

    Igor.

    Hi Igor,

    I Couldn't find 6100-09-00-1391 and 6100-09-12-1864 packages,

    below, i found two on IBM Fixcentral look alike, is this SP you mentioned before ?

    6100-09-00-1341  

    6100-09-12-1846

    Hi Ary,

    sorry for my typo - I rewrote the numbers from my phone...

    Your ID's are right :-)

    Just take into account that both steps require system reboot as the kernel and majority of system libraries are updated.

    Regards Igor.

    Check the libc version - the latest for AIX 6.1 is: 

    bos.rte.libc   6.1.9.400

    from TL09 SP12
