    exec(): 0509-036 Cannot load program /usr/sbin/sshd because of the following errors:
            0509-130 Symbol resolution failed for sshd because:
            0509-136   Symbol __stack_chk_fail (number 230) is not exported from
                       dependent module /usr/lib/libc.a(shr.o).
            0509-136   Symbol __ssp_canary_word (number 245) 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" ?
