Start with RFC 4251, the Secure Shell Protocol Architecture. It will lead you to other RFCs. ssh data transfer has no concept of "text" or "binary". It just moves bytes around. According to the current IBM Ported Tools for z/OS User Guide, z/OS assumes that scp refers to text data and that sftp refers to binary data. If you run the scp client in verbose mode, I think it will tell you excaly what command it is issuing (a form of ssh[1]). FWIW, I've seen web browsers explicitly set "binary" mode on an ftp:// URL because they *assume* that all data everywhere is represented the same way. :-( Alan Altmark z/VM Development IBM Endicott ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
