=head1 DESCRIPTION
|
|
|
|
This command implements a generic SSL/TLS client which
|
|
connects to a remote host using SSL/TLS. It can request a page from the server
|
|
and includes the time to transfer the payload data in its timing measurements.
|
|
It measures the number of connections within a given timeframe, the amount of
|
|
data transferred (if any), and calculates the average time spent for one
|
|
connection.

=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-connect> I<host>:I<port>
|
|
|
|
This specifies the host and optional port to connect to.
|
|
|
|
=item B<-www> I<page>
|
|
|
|
This specifies the page to GET from the server. A value of '/' gets the
|
|
F<index.html> page. If this parameter is not specified, then this command
|
|
will only perform the handshake to establish SSL connections but not transfer
|
|
any payload data.
|
|
|
|
=item B<-cert> I<certname>
|
|
|
|
The certificate to use, if one is requested by the server. The default is
|
|
not to use a certificate. The file is in PEM format.
|
|
|
|
=item B<-key> I<keyfile>
|
|
|
|
The private key to use. If not specified then the certificate file will
|
|
be used. The file is in PEM format.
|
|
|
|
=item B<-verify> I<depth>
|
|
|
|
The verify depth to use. This specifies the maximum length of the
|
|
server certificate chain and turns on server certificate verification.
|
|
Currently the verify operation continues after errors so all the problems
|
|
with a certificate chain can be seen. As a side effect the connection
|
|
will never fail due to a server certificate verify failure.
|
|
|
|
=item B<-new>
|
|
|
|
Performs the timing test using a new session ID for each connection.
|
|
If neither B<-new> nor B<-reuse> are specified, they are both on by default
|
|
and executed in sequence.
|
|
|
|
=item B<-reuse>
|
|
|
|
Performs the timing test using the same session ID; this can be used as a test
|
|
that session caching is working. If neither B<-new> nor B<-reuse> are
|
|
specified, they are both on by default and executed in sequence.
|
|
|
|
=item B<-bugs>
|
|
|
|
There are several known bugs in SSL and TLS implementations. Adding this
|
|
option enables various workarounds.
|
|
|
|
=item B<-cipher> I<cipherlist>
|
|
|
|
This allows the TLSv1.2 and below cipher list sent by the client to be modified.
|
|
This list will be combined with any TLSv1.3 ciphersuites that have been
|
|
configured. Although the server determines which cipher suite is used it should
|
|
take the first supported cipher in the list sent by the client. See
|
|
L<openssl-ciphers(1)> for more information.
|
|
|
|
=item B<-ciphersuites> I<val>
|
|
|
|
This allows the TLSv1.3 ciphersuites sent by the client to be modified. This
|
|
list will be combined with any TLSv1.2 and below ciphersuites that have been
|
|
configured. Although the server determines which cipher suite is used it should
|
|
take the first supported cipher in the list sent by the client. See
|
|
L<openssl-ciphers(1)> for more information. The format for this list is a
|
|
simple colon (":") separated list of TLSv1.3 ciphersuite names.
|
|
|
|
=item B<-time> I<length>
|
|
|
|
Specifies how long (in seconds) this command should establish connections
|
|
and optionally transfer payload data from a server. Server and client
|
|
performance and the link speed determine how many connections it
|
|
can establish.

=head1 NOTES
|
|
|
|
This command can be used to measure the performance of an SSL connection.
|
|
To connect to an SSL HTTP server and get the default page the command
|
|
|
|
openssl s_time -connect servername:443 -www / -CApath yourdir -CAfile yourfile.pem -cipher commoncipher [-ssl3]
|
|
|
|
would typically be used (https uses port 443). I<commoncipher> is a cipher to
|
|
which both client and server can agree, see the L<openssl-ciphers(1)> command
|
|
for details.
|
|
|
|
If the handshake fails then there are several possible causes, if it is
|
|
nothing obvious like no client certificate then the B<-bugs> and
|
|
B<-ssl3> options can be tried
|
|
in case it is a buggy server. In particular you should play with these
|
|
options B<before> submitting a bug report to an OpenSSL mailing list.
|
|
|
|
A frequent problem when attempting to get client certificates working
|
|
is that a web client complains it has no certificates or gives an empty
|
|
list to choose from. This is normally because the server is not sending
|
|
the clients certificate authority in its "acceptable CA list" when it
|
|
requests a certificate. By using L<openssl-s_client(1)> the CA list can be
|
|
viewed and checked. However, some servers only request client authentication
|
|
after a specific URL is requested. To obtain the list in this case it
|
|
is necessary to use the B<-prexit> option of L<openssl-s_client(1)> and
|
|
send an HTTP request for an appropriate page.
|
|
|
|
If a certificate is specified on the command line using the B<-cert>
|
|
option it will not be used unless the server specifically requests
|
|
a client certificate. Therefore, merely including a client certificate
|
|
on the command line is no guarantee that the certificate works.
|
|
|
|
=head1 BUGS
|
|
|
|
Because this program does not have all the options of the
|
|
L<openssl-s_client(1)> program to turn protocols on and off, you may not
|
|
be able to measure the performance of all protocols with all servers.
|
|
|
|
The B<-verify> option should really exit if the server verification
|
|
fails.
|
|
|
|
=head1 HISTORY
|
|
|
|
The B<-cafile> option was deprecated in OpenSSL 3.0.
