Hi Ivan,

do you have Internet access from your AIX LPAR? Can you download other files?

Hi!

Sounds like general network / proxy related problems.  Can you download files from other websites to that system?

Best regards,

Hi Ivan,

It looks like a firewall issue. I ran into the same problem and had to submit a firewall request to my network team to open that port from my server to the ibm site. Once that got done, I was good to go.

You can try to telnet to see if you can connect.

# telnet public.dhe.ibm.com 443
Trying...
Connected to public.southdata.ibm.com.
Escape character is '^]'.
^CConnection closed.

Good luck,

Rubi

Hi!

That looks like it fails an earlier state protocol wise, before even reaching firewalls.

Two question:  Do you know if this machine is connected directly to the internet? Then it seems you name resolution has a problem.  Probably you just have to add some nameservers?

Or if your machine is not directly connected, but via proxy:  You'll have to set the HTTPS_PROXY="http://yourproxy:yourport/" variable.  Otherwise the script will try to download directly.

Best regards,

What happens if you use the IP instead fo the name? I ran an nslookup on public.dhe.ibm.com to get the IP. 

# telnet 170.225.126.18 443
Trying...
Connected to 170.225.126.18.
