Hello,
It looks like you have successfully transferred the agent binary to your machine and then try to execute it but can't. Did the agent binary actually transfer successfully? If so, then please try and run: chmod 555 nolio_agent_aix_6_5_0_b10007.sh
and then try to run: ./nolio_agent_aix_6_5_0_b10007.sh
I'm not familiar with a wget command that downloads and then executes but I'm assuming that you're passing some kind of argument to wget that tells it to execute it after it downloads it. If the suggestion doesn't work then please confirm the exact wget command you are/were using when getting that error (minus the servername) as well as the permissions of the folder that you're in while running the command.
Kind regards,
Gregg
