###########################################################################
# Experimental hooks are available to run tests remotely on machines that
# are able to run curl but are unable to run the test harness.
# The following sections need to be modified:
#
# $HOSTIP, $HOST6IP - Set to the address of the host running the test suite
# $CLIENTIP, $CLIENT6IP - Set to the address of the host running curl
# runclient, runclientoutput - Modify to copy all the files in the log/
# directory to the system running curl, run the given command remotely
# and save the return code or returned stdout (respectively), then
# copy all the files from the remote system's log/ directory back to
# the host running the test suite. This can be done a few ways, such
# as using scp & ssh, rsync & telnet, or using a NFS shared directory
# and ssh.
#
# 'make && make test' needs to be done on both machines before making the
# above changes and running runtests.pl manually. In the shared NFS case,
# the contents of the tests/server/ directory must be from the host
# running the test suite, while the rest must be from the host running curl.
#
# Note that even with these changes a number of tests will still fail (mainly
# to do with cookies, those that set environment variables, or those that
# do more than touch the file system in a <precheck> or <postcheck>
# section). These can be added to the $TESTCASES line below,
# e.g. $TESTCASES="!8 !31 !63 !cookies..."
#
# Finally, to properly support -g and -n, checktestcmd needs to change
# to check the remote system's PATH, and the places in the code where
# the curl binary is read directly to determine its type also need to be
# fixed. As long as the -g option is never given, and the -n is always
# given, this won't be a problem.
# These should be the only variables that might be needed to get edited:
