Re: PTF download failures

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

We use the FTP method 99 44/100ths percent of the time. WOrks great.

Things I have seen that bollix up the process:

Firewalls. Examples:
	Cisco Firepower often thinks the PTF images are PDFs (Not making that 
up!) and complains they are 'too big to be valid' so they disconnect 
after some number of bytes.
	Simple download limits. File too big, you only get part of it.
	Connection timeout in the firewall where the transfer takes longer than 
the timeout. This is a problem with FTP due to the whacko port stuff it 
does (Control port 21 but data port = random.)

Seems like it would die at roughly the same spot on one of the largest iso images.  I had opened up a case with IBM.  They did a BUNCH of stuff but basically pointed to an issue with our network.  Our network consultant wasn't too helpful so I just use FileZilla to get them from IBM's site to my PC and then use FileZilla again to put them on the lpar.  This works.
