We switched from SFT to MFT. Don't know (or care) why - that was a 30,000-foot decision. Now I am picking up the pieces. Here's my MFT stuff:

Code:
locsite fwfriendly
ASCII CRLF
cd fins
cd CB Reports
PUT 'EXCH300.Z3000ALL.FILE' TESST_3.TXT
QUIT


Here's the flaming results:


Code:
EZA1736I locsite friendly
EZA1460I Command:
EZA1736I ASCII CRLF
EZA1701I >>> TYPE A
200 Command okay,
EZA1460I Command:
EZA1736I cd fins
EZA1701I >>> CWD fins
250 Directory changed to /fins
EZA1460I Command:
EZA1736I cd CB Reports
EZA1701I >>> CWD CB Reports
250 Directory changed to /fins/CB Reports
EZA1460I Command:
EZA1736I PUT 'EXCH300.Z3000ALL.FILE' TESST_3.TXT
EZA1701I >>> SITE FIXrecfm 383 LRECL=383 RECFM=FB BLKSIZE=27959
502 Command SITE not implemented for FIXRECFM
EZA1701I >>> PASV
227 Entering Passive Mode (nnn,nnn,n,nn,nn,nnn)
EZA1701I >>> STOR TEST_3.TXT
150 File status okay; about to open data connection.
EZA2870I TLS security mechanism negotiation failed - data connection closed
425 Can't open data connection.
EZA1735I Std Return Code = 27425, Error Code = 000417
EZA1701I >>> QUIT
221 Goodbye.


1. I can probably put the two CD commands in one
2. What the heck am I missing with the TLS Security error???

Our Network Operations team doesn't realize that there is an IBM mainframe, so they have been absolutely no help. What do you guys suggest? This wasn't happening in test!

With FTP you probably would have to code:
Code:
PGM=FTP,PARM='-a TLS -e -x'

I've faced similar connection issues with handshake, One possible cause is that, atleast one encryption algorithm needs to be common between the client and Server to communicate. If there are no common negotiating algorithms then handshake would fail.

I would look at the allowed protocols in /etc/pagent and compare to what the other side is trying to use.

I finally found a network guy who was willing to work with me and we discovered that the clown who set up the folders on our MFT server had set a higher access authority on the subfolder over the root folder.

This means that we had to develop a "back door" solution to access the production subfolder through the test root folder. These people have jobs and they walk among us, having no accountability for their stupidity.
