28 help="Run a glibc test COMMAND on the remote machine HOST, via ssh,
29 passing environment variables, preserving the current working directory,
30 and respecting quoting.
32 If the '--ssh SSH' flag is present, use SSH as the SSH command,
33 instead of ordinary 'ssh'.
35 To use this to run glibc tests, invoke the tests as follows:
37 $ make test-wrapper='ABSPATH/cross-test-ssh.sh HOST' tests
39 where ABSPATH is the absolute path to this script, and HOST is the
40 name of the machine to connect to via ssh.
42 If you need to connect to the test machine as a different user, you
43 may specify that just as you would to SSH:
45 $ make test-wrapper='ABSPATH/cross-test-ssh.sh USER@HOST' tests
47 Naturally, the remote user must have an appropriate public key, and
48 you will want to ensure that SSH does not prompt interactively for a
49 password on each connection.
51 HOST and the build machines (on which 'make check' is being run) must
52 share a filesystem; all files needed by the tests must be visible at
53 the same paths on both machines.
55 ${progname} runs COMMAND in the same directory on the HOST that
56 ${progname} itself is run in on the build machine.
58 The command and arguments are passed to the remote host in a way that
59 avoids any further shell substitution or expansion, on the assumption
60 that the shell on the build machine has already done them
61 appropriately.
63 ${progname} propagates the values all environment variables through to
64 the remote target, except the following:
