SICS Client Configuration
Currently, SICS clients are written in Tcl/TK. This means that these programs
are just scripts wich can be edited. Such editing is necessary in order to let
the clients know how to connect to a server. All client configuration
information is kept in an array named INI which is at the very top of the file.
Configurable values in INI are:
- DefUser
- The SICS user name for the initial logon to the server when connecting.
- DefPasswd
- The password of the default user for logon.
- ServerPort
- The port number where the server is listening.
- InterruptPort
- The interrupt port number of the server.
- box
- The computer on which the SICS server is running.
- usPasswd
- The password of the SICS user. This is used as password when setting
user rights from the menu.
- muPasswd
- The password of the SICS managers. This is used as password when setting
user rights from the menu.
- logpath
- Only for the command line client. On request of the SICS users each
command line client logs all I/O into a logfile. This logfile resides on the
computer running the SICS server. This allows SICS managers to check what
user have done to the machine. The logpath element defines the path to the
directory where the automatically
created log files are kept on the computer running the SICS server.
The rest of the parameters and the file is programmers only. Reasonable values
for those parameters can be found in the server configuration file. And of course,
you need to know where the server is running.
At the very top of the client script there is the full path name of the Tcl/TK
interpreter to run in. This must be a wish for the command line client and a
blt_wish for the status display client. This may need to be changed if a client
comes up with: command not found. Valid copies of these executables can be
found in /data/lnslib/bin. Tcl/TK needs own libraries of scripts as well. The
places where these libraries sit is defined through the environment variables
TCL_LIBRARY and TK_LIBRARY. Suitable libraries are under /data/lnslib. For
details inspect /data/lnlib/bin/lns.login. When moving a client to a machine
where the clients need to run stand alone this stuff needs to be copied and
TCL_LIBRARY and TK_LIBRARY properly defined in the .login file.
