# Commands tested in this file: socket.

#
# Running socket tests with a remote server:
# ------------------------------------------
#
# Some tests in socket.test depend on the existence of a remote server to
# which they connect. 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. If all fails, a message is printed and the tests
# using the remote server are not performed.
