Hi fswarbrick,
As an idea you can do followed:
I.
- git clone your_repo from machine with internet
- copy via ftp or sftp repo folder to mainframe
- you may want to use autotag utility on mainframe in this folder. cd your_repo ; autotag -R -L 12 .
II. As a second option I think you can setup git server with repo you need on some of your Linux or Windows machines in the LAN which have both access internet and mainframe. After that you will be able git clone from your local network server.
Thanks,
Alexander
