NetEx EFT213 Reference Manual Rel 5.4

This section is intended for users who are currently running the NetEx/eFT Initiator from any local host, regardlessof operating system, and would like to establish a network connection into a IBM z/OS host. Theinformation provided here and in “File Handling Under IBM z/OS NetEx/eFT”, should be enough to help anon-z/OS user start being productive in a very short period of time. z/OS users should also reference thesesections to become comfortable with how NetEx/eFT operates in the environment. The IBM z/OS Time SharingOption (TSO/E) environment is presented to the remote user for interaction.Connecting to an IBM z/OS HostA NetEx/eFT network connection is established into an IBM z/OS environment by means of a process knownas the Multiplex Server (MUX Server). The task of the MUX Server is to listen on the network for remoteconnect/login requests. Upon receiving a connect request, the MUX Server starts a VTAM session and issuesa LOGON command to TSO/E. TSO/E then validates the user ID and password to ensure that proper securityis checked. Finally, the MUX Server, after monitoring a successful logon through TSO/E, starts up aNetEx/eFT Helper program under the TSO/E session. The Helper and remote Initiator then exchange connectioninformation through the MUX Server, and network connection is established.As seen above, connections to an IBM z/OS host typically requires a TSO/E user name and password. Forexample, if a user name on host MVS003 is SMITH with a password of JOHN, type:eFT> connect mvs003 smith johnSome IBM z/OS hosts with additional security packages (such as RACF) may require periodic changing of auser’s password. This can be accomplished in NetEx/eFT by using the TSO/E syntax password/newpasswordFor example, to change the password in the previous example from JOHN to JACK, type:eFT> connect mvs003 smith john/jackAdditional parameters to the TSO/E logon command can be provided in the CONNECT command followingthe password. For example, if one does not want to receive mail messages during logon processing(NOMAIL), type:eFT> connect mvs003 smith john nomailIBM z/OS Remote User’s GuideIf multiple TSO/E logon parameters are required, they must be enclosed in double quotes following the password.For example, to initiate a session with a different logon procedure (PROC) as well as disabling mail,type:eFT> connect mvs003 smith john “proc(MYJCL) nomail”The CONNECT qualifier values ACCOUNT and PROFILE are mapped to the TSO/E LOGON commandkeywords ACCT and PROC. A user can use SET CONNECT to establish default values or the NetEx/eFTresponder on the IBM z/OS host can provide defaults. The following CONNECT command is equivalent tothe previous example:eFT> connect mvs003 smith john -profile MYJCL nomailSome TSO/E logon procedures may prompt for additional information (e.g., security or accounting information).Responses to these prompts can be provided following the TSO/E logon parameters (or a null stringif no logon parameters are required). For example, if the normal TSO/E logon procedure prompts for a departmentcode (ENG01) and a charge number (7743), type:eFT> connect mvs003 smith john “ ” ENG01 7743REF-eFT213-R5.4-08 IBM z/OS Remote User’s Guide Page 35
