When the SET-FTP-TELNET-PARAMETERS command is executed (see "Installing FTP and TELNET via SDF command"/"Configuring TELNET using the SET-FTP-TELNET- PARAMETERS installation command"), an option file is generated in which the individual TELNET server parameters are stored as options. The default file name of the option file is:
SYSDAT.TCP-IP-AP.nnn.TELNETD.OPT
If a file of this name exists in the TELNET server’s execution ID, it is interpreted by the TELNET server’s start file (default file name: SYSENT.TCP-IP-AP.nnn.TELNETD) when the TELNET server is started and the TELNET server is configured accordingly.
You can thus make changes to the TELNET server parameters via the option file without needing to repeat installation using the SET-FTP-TELNET-PARAMETERS command.
If you want to use a file with a different name as the option file, specify the following option in the start file:
-M option-file-name
This file is then interpreted in place of any file named SYSDAT.TCP-IP-AP.nnn.TELNETD.OPT which may exist.
The following priorities apply for the options:
Options specified in the start procedure
Options which
are included in the option file specified via the -M option or,
if no -M option was specified, which are included in the default option file SYSDAT.TCP-IP-AP.nnn.TELNETD.OPT.
Option file and parameter line options
In the option file you can also specify the parameter line options supported in earlier versions. Mixed application of option file and options in the parameter line is also possible. If a particular option is specified both in the parameter line and in the option file, the option specified in the parameter line has priority.
Notation of the options in the option file
The various options must be entered in the option file according to the following rules:
Any number of options can be contained in a line
If an option’s arguments extend over more than one line, each line that is to be continued must be terminated with the continuation character “\”.
A line beginning with the character “#” in column 1 is ignored when the file is read in.
No distinction is made between upper and lower case in the option names.
