Controlling File Transfer
The current Secure Shell protocol and current clients do not transfer
any information about the files to be transferred, only the file
contents as a byte stream. This is sufficient for Unix-type files if the
sender and receiver use the same CCS.
SSH Tectia Server for IBM z/OS needs more information: which transfer format to use, what code sets
are involved, and what the file characteristics are. When SSH Tectia is used at
both ends, the information can be relayed by using the Site commands of
scpg3 and sftpg3, or read from environment variables. When
a third-party Secure Shell client is used together with SSH Tectia Server for IBM z/OS, the
information can be either encoded in the filename (advice string), read from
a file transfer profile, or read from environment variables.
SSH Tectia Server for IBM z/OS needs more information: which transfer format to use,
what code sets are involved, and what the file characteristics
are. Some of this information may be transported in the protocol in
the future versions of SSH Tectia Client. In SSH Tectia Server for IBM z/OS, the information is
either encoded in the filename (Advice String), read from a
file transfer profile, or in case of file transfer client from
environment variables.
