RE: How to Specify the FTP source IP address ?

It would involve routing in the TCP/IP stack, which requires knowledge
of the complete configuration. I can't imagine why the network would
NOT already be configured to favor the best links. FTP isn't always
secure, so that might be an issue. If you're VIPA, then it's more
complicated. If the other server is in an adjoining LPAR, then
hypersocket would beat OSA. At one time, there was FUD (in my mind
anyway) about LPAR-to-LPAR transfer over the same OSA.

Plus just moving the traffic to the OSA won't fix other parts of the
network. If it's not Gbit all the way to the other server, it won't
matter.

Bottom line, the FTP client can't specify the path, it's the z/OS TCP/IP
admins who can influence path selection.



Hi Len,
you're right , I would like to have the z/OS FTP client cross over
the
preferred one, OSA card ,which is 1 gb/sec ,much faster thatn the rest
ones. Do you know how to specify that ?
