Steps for setting up for rlogin

Before you begin:

You need to set up the appropriate security as described in:
You also need to customize the SUBFILESYSTYPE statement in BPXPRMxx to include TCP/IP.

Perform the following steps to set up for rlogin.

Set up security for the inetd and rlogind daemons. See Steps for preparing the security program for daemons.

Establish the connection between TCP/IP and z/OS® UNIX; see z/OS Communications Server for more information.
1. Define port 513 in /etc/services (if this file is to be used) or in the hlq.ETC.SERVICES data set, where hlq is the prefix defined by DATASETPREFIX in the TCP/IP profile ("TCPIP" by default). If /etc/services is defined, it will be used instead of hlq.ETC.SERVICES. The format of the line is:
```
 login		513/tcp
```
2. IPL or re-IPL if needed.
3. Start TCP/IP.
_______________________________________________________________
Customize /etc/inetd.conf. It tells inetd how to handle Internet service requests on Internet sockets. If you do not have that file, copy it from /samples.
Example:
```
cp /samples/inetd.conf /etc/inetd.conf
```
Make these changes in the file:
1. Change the user ID of the login server (which is rlogind) to an ID with daemon authority.
```
login stream tcp nowait OMVSKERN /usr/sbin/rlogind rlogind -m
```
2. Comment out any servers that are not needed by putting a # in the first column.
_______________________________________________________________
Start the inetd daemon. It is typically started from /etc/rc, which is executed when the system is initialized. Put these lines in /etc/rc, or uncomment them out, as the case might be:
```
_BPX_JOBNAME='INETD' /usr/sbin/inetd /etc/inetd.conf&
```
Tips:
- When you start inetd from the shell, you need to do it from an OMVS session.
- If TCP/IP is not yet up, you will receive error messages, but inetd will try again in a few minutes.
- To obtain debugging information, issue:
```
/usr/sbin/inetd -d
```
- To verify that inetd is listening on port 513, issue the TSO NETSTAT INTERVAL command and check the output.

When you are done, you can issue the rlogin command to log in from a remote UNIX system.
