sl@0: # Running socket tests with a remote server:
sl@0: # ------------------------------------------
sl@0: # 
sl@0: # Some tests in socket.test depend on the existence of a remote server to
sl@0: # which they connect. The remote server must be an instance of tcltest and it
sl@0: # must run the script found in the file "remote.tcl" in this directory. You
sl@0: # can start the remote server on any machine reachable from the machine on
sl@0: # which you want to run the socket tests, by issuing:
sl@0: # 
sl@0: #     tcltest remote.tcl -port 2048	# Or choose another port number.
sl@0: # 
sl@0: # If the machine you are running the remote server on has several IP
sl@0: # interfaces, you can choose which interface the server listens on for
sl@0: # connections by specifying the -address command line flag, so:
sl@0: # 
sl@0: #     tcltest remote.tcl -address your.machine.com
sl@0: # 
sl@0: # These options can also be set by environment variables. On Unix, you can
sl@0: # type these commands to the shell from which the remote server is started:
sl@0: # 
sl@0: #     shell% setenv serverPort 2048
sl@0: #     shell% setenv serverAddress your.machine.com
sl@0: # 
sl@0: # and subsequently you can start the remote server with:
sl@0: # 
sl@0: #     tcltest remote.tcl
sl@0: # 
sl@0: # to have it listen on port 2048 on the interface your.machine.com.
sl@0: #     
sl@0: # When the server starts, it prints out a detailed message containing its
sl@0: # configuration information, and it will block until killed with a Ctrl-C.
sl@0: # Once the remote server exists, you can run the tests in socket.test with
sl@0: # the server by setting two Tcl variables:
sl@0: # 
sl@0: #     % set remoteServerIP <name or address of machine on which server runs>
sl@0: #     % set remoteServerPort 2048
sl@0: # 
sl@0: # These variables are also settable from the environment. On Unix, you can:
sl@0: # 
sl@0: #     shell% setenv remoteServerIP machine.where.server.runs
sl@0: #     shell% senetv remoteServerPort 2048
sl@0: # 
sl@0: # The preamble of the socket.test file checks to see if the variables are set
sl@0: # either in Tcl or in the environment; if they are, it attempts to connect to
sl@0: # the server. If the connection is successful, the tests using the remote
sl@0: # server will be performed; otherwise, it will attempt to start the remote
sl@0: # server (via exec) on platforms that support this, on the local host,
sl@0: # listening at port 2048. If all fails, a message is printed and the tests
sl@0: # using the remote server are not performed.
