You can log in directly to the z/OS® UNIX® shell from a system that is connected
to z/OS through
TCP/IP.
Use one of the following methods:
- rlogin
- You can rlogin (remote log in) to the shell from a system that has rlogin
client support. To log in, use the rlogin command syntax supported at your
site.
- telnet
- You can telnet into the shell. To log in, use the telnet command from
your workstation or from another system with telnet client support.
As shown in Figure 1, each of these
methods requires the inetd daemon to be set up and active on the z/OS system.

from a terminal
There are some differences between the asynchronous terminal support (direct
shell login) and the 3270 terminal support (OMVS command):
- You cannot switch to TSO/E. However, you can use the TSO SHELL command
to run a TSO/E command from your shell session.
- You cannot use the ISPF editor (this includes the oedit command,
which invokes ISPF edit).
- You can use the UNIX vi editor, and other interactive utilities that
depend on receiving each keystroke, without hitting the Enter key.
- You can use UNIX-style command-line editing.
