When the SET-FTP-TELNET-PARAMETERS command is executed (see "Installing FTP and TELNET via SDF command") an option file is generated in which the various FTP server parameters are stored. The default file name for the option file is:
SYSDAT.TCP-IP-AP.nnn.FTPD.OPT
under $TSOS, the execution ID.
If a file with this name exists in the FTP server’s execution ID it is interpreted when the FTP server is started via the FTP server start file (default file name: SYSENT.TCP-IP-AP.nnn.FTPD), and the FTP server is configured accordingly.
You can thus make changes to the FTP server parameters via the option file without needing to start installation again using the SET-FTP-TELNET-PARAMETERS command.
If you want to use a file with a different name as the option file, enter the following option in the start file:
-M option-file-name
Option file and parameter line options
You can also specify the parameter line options supported in earlier versions. In this case you can choose between the familiar option name consisting of one character and the new, more easily recognizable name consisting of several characters.
Mixed application of the option file and options in the parameter line is also possible. Here only option names comprising one character are permitted in the parameter line. If a particular option is specified in both 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:
Each option must be in a separate 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.
Description of the options
The individual options are described below:
With the options that correspond to the parameter line options already supported, the name, which consists of one character, is specified as an alias name.
The options which govern TLS support in the FTP server are marked by the prefix “tls” in the option name.
