* EXIT_SUCCESS and EXIT_FAILURE are defined in stdlib.h, not sysexits.h
so no need to include the latter.
* No need to include pthread.h.
* Remove the no longer used delay() function.
This also removes the reliance on nanosleep().
* Remove get_tcp_windowsize() and set_tcp_windowsize() which are unused.
These days, iperf uses get/setsockopt() with SO_SNDBUF SO_RCVBUF directly.
Don't make OpenSSL detection error out unless --with-openssl explicitly given.
This fixes the out-of-the-box build on macOS, which doesn't include
headers, etc. for OpenSSL by default. The configure script still
errors out if the user specifies a --with-openssl flag but for some
reason the build host's OpenSSL is broken or can't be used.
* Regen.
* Add configurable timeout for the setup of the control connection.
This is specified using the new --connect-timeout option, with an
integer parameter in ms. The iperf3 client will wait for this
amount of time for the setup of the control connection to the
server. If this option is not given, the OS default for TCP
connection setup is used. Specifying a smaller connection timeout
allows faster detection of a down / unresponsive iperf3 server.
The implementation uses a variation on the timeout_connect()
function from OpenBSD's netcat utility.
Fixes#216.
Add an optional mode that requires clients to authenticate with the server.
In this mode, clients need to provide a username and a password, which are checked against a password file on the server. The authentication credentials are protected by an RSA public keypair...the encrypted credentials are sent along with the test parameters.
Operationally the use of this feature places the following additional requirements on the build and installation of iperf3:
o The presence of the OpenSSL headers and libraries to build iperf3, and the libraries available on the client and server at runtime.
o Generation of an RSA public keypair; the private part is used by the server and the public part must be distributed to the clients.
o Username/password pairs for all authorized users, to be stored in a file on the server.
o Loose time synchronization between the server and clients (to within approximately 30 seconds).
o Appropriate command-line flags given on the client and server.
Note that iperf3 can be built and run as before, without fulfilling any of these requirements.
Partial documentation for this feature is included in this commit. It is anticipated that additional documentation text and editing will follow this merge.
Submitted by @ralcini. First suggested by @codyhanson in pull request #242.
* Remove unused hstrerror(), bad nanosleep() message in configure.ac (#503)
* Remove dead code involving h_errno and hstrerror()
h_errno was formerly set as a side effect of a failed
gethostbyname(3) call, but this function has been
deprecated.
