Installation information

The files used in the z/OS® UNIX Telnet server and their locations in the z/OS UNIX file system are as follows:

/etc/services

The ports for each application are defined here. For example:

otelnet xxxx/tcp

where xxxx is the port that inetd should listen on for otelnet.

/etc/syslog.conf

The configuration parameters for usage of syslogd are defined in this file. otelnetd writes to syslog facility local1.

/etc/inetd.conf

The configuration parameters for all applications started by inetd are defined in this file.

/usr/sbin/otelnetd

This is a symbolic link to /usr/lpp/tcpip/sbin/otelnetd. /usr/lpp/tcpip/sbin/otelnetd is a sticky-bit file. The OTELNETD member of SEZALOAD contains the executable code for the Telnet server.

/etc/banner

This file contains a login message that is printed to the client's screen after the client logs in, unless the -h option is specified. Store the banner in this file.

/etc/otelnetd.banner

This file contains a message that is printed to the client's screen prior to the login prompt when the user connects to the server, unless the -h option is specified. Store the banner in this file.

/etc/utmpx

This file is updated by the call to fsumoclp. It contains a list of all the users who are logged in with their associated tty.

/dev/ptypXXXX and /dev/ttypXXXX

These special device files represent pseudoterminals (ptys); they are used by the z/OS UNIX Telnet server and other programs.

Note: For information on allocating more of these files for more connections, see z/OS UNIX System Services Planning.

/usr/share/lib/terminfo

The descriptions of supported terminals are stored here. For more information, see z/OS UNIX System Services Planning.

/usr/lib/nls/msg/C/tnmsgs.cat

The message catalog used by the z/OS UNIX Telnet server is stored here.

If the message catalog does not exist, the software will use the messages hard-coded within the software by default. These messages duplicate the English message catalog that is shipped with the product.

/usr/man/C/cat1/otelnetd.1

This file contains the associated manual (man) pages for the z/OS UNIX Telnet server. It provides online help for the user.
