The remote server must be an instance of tcltest and it +# must run the script found in the file "remote.tcl" in this directory. You +# can start the remote server on any machine reachable from the machine on +# which you want to run the socket tests, by issuing: +# +# tcltest remote.tcl -port 2048 # Or choose another port number. +# +# If the machine you are running the remote server on has several IP +# interfaces, you can choose which interface the server listens on for +# connections by specifying the -address command line flag, so: +# +# tcltest remote.tcl -address your.machine.com +# +# These options can also be set by environment variables. On Unix, you can +# type these commands to the shell from which the remote server is started: +# +# shell% setenv serverPort 2048 +# shell% setenv serverAddress your.machine.com +# +# and subsequently you can start the remote server with: +# +# tcltest remote.tcl +# +# to have it listen on port 2048 on the interface your.machine.com. +# +# When the server starts, it prints out a detailed message containing its +# configuration information, and it will block until killed with a Ctrl-C. +# Once the remote server exists, you can run the tests in socket.test with the +# server by setting two Tcl variables: +# +# % set remoteServerIP <name or address of machine on which server runs> +# % set remoteServerPort 2048 +# +# These variables are also settable from the environment. On Unix, you can: +# +# shell% setenv remoteServerIP machine.where.server.runs +# shell% senetv remoteServerPort 2048 +# +# The preamble of the socket.test file checks to see if the variables are set +# either in Tcl or in the environment; if they are, it attempts to connect to +# the server. If the connection is successful, the tests using the remote +# server will be performed; otherwise, it will attempt to start the remote +# server (via exec) on platforms that support this, on the local host, +# listening at port 2048.
