=head1 DESCRIPTION
=head1 OPTIONS
+In addition to the options below the B<s_server> utility also supports the
+common and server only options documented in the
+L<SSL_CONF_cmd(3)|SSL_CONF_cmd(3)/SUPPORTED COMMAND LINE COMMANDS> manual
+page.
+
=over 4
=item B<-accept port>
the TCP port to listen on for connections. If not specified 4433 is used.
+=item B<-naccept count>
+
+The server will exit after receiving B<number> connections, default unlimited.
+
=item B<-context id>
sets the SSL context id. It can be given any string value. If this option
for example the DSS cipher suites require a certificate containing a DSS
(DSA) key. If not specified then the filename "server.pem" will be used.
+=item B<-certform format>
+
+The certificate format to use: DER or PEM. PEM is the default.
+
=item B<-key keyfile>
The private key to use. If not specified then the certificate file will
be used.
+=item B<-keyform format>
+
+The private format to use: DER or PEM. PEM is the default.
+
+=item B<-pass arg>
+
+the private key password source. For more information about the format of B<arg>
+see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)|openssl(1)>.
+
=item B<-dcert filename>, B<-dkey keyname>
specify an additional certificate and private key, these behave in the
a server can support clients which only support RSA or DSS cipher suites
by using an appropriate certificate.
+=item B<-dcertform format>, B<-dkeyform format>, B<-dpass arg>
+
+additional certificate and private key format and passphrase respectively.
+
=item B<-nocert>
if this option is set then no certificate is used. This restricts the
if this option is set then no DH parameters will be loaded effectively
disabling the ephemeral DH cipher suites.
+=item B<-no_ecdhe>
+
+if this option is set then no ECDH parameters will be loaded effectively
+disabling the ephemeral ECDH cipher suites.
+
=item B<-no_tmp_rsa>
certain export cipher suites sometimes use a temporary RSA key, this option
client does not have to send one, with the B<-Verify> option the client
must supply a certificate or an error occurs.
+=item B<-crl_check>, B<-crl_check_all>
+
+Check the peer certificate has not been revoked by its CA.
+The CRL(s) are appended to the certificate file. With the B<-crl_check_all>
+option all CRLs of all CAs in the chain are checked.
+
=item B<-CApath directory>
The directory to use for client certificate verification. This directory
is also used in the list of acceptable client CAs passed to the client when
a certificate is requested.

+
+Set different peer certificate verification options.
+See the L<B<verify>|verify(1)> manual page for details.
+
=item B<-state>
prints out the SSL session states.
print extensive debugging information including a hex dump of all traffic.
+=item B<-msg>
+
+show all protocol messages with hex dump.
+
+=item B<-trace>
+
+show verbose trace output of protocol messages. OpenSSL needs to be compiled
+with B<enable-ssl-trace> for this option to work.
+
+=item B<-msgfile>
+
+file to send output of B<-msg> or B<-trace> to, default standard output.
+
=item B<-nbio_test>
tests non blocking I/O
inhibit printing of session and certificate information.
+=item B<-psk_hint hint>
+
+Use the PSK identity hint B<hint> when using a PSK cipher suite.
+
+=item B<-psk key>
+
+Use the PSK key B<key> when using a PSK cipher suite. The key is
+given as a hexadecimal number without leading 0x, for example -psk
+1a2b3c4d.
+
=item B<-ssl2>, B<-ssl3>, B<-tls1>, B<-no_ssl2>, B<-no_ssl3>, B<-no_tls1>
these options disable the use of certain SSL or TLS protocols. By default
there are several known bug in SSL and TLS implementations. Adding this
option enables various workarounds.
+=item B<-brief>
+
+only provide a brief summary of connection parameters instead of the
+normal verbose output.
+
=item B<-hack>
this option enables a further workaround for some some early Netscape
the preference order, the order of the server cipherlist irrelevant. See
the B<ciphers> command for more information.
+=item B<-serverpref>
+
+use the server's cipher preferences, rather than the client's preferences.
+
+=item B<-tlsextdebug>
+
+print out a hex dump of any TLS extensions received from the server.
+
+=item B<-no_ticket>
+
+disable RFC4507bis session ticket support.
+
=item B<-www>
sends a status message back to the client when it connects. This includes
current directory, for example if the URL https://myhost/page.html is
requested the file ./page.html will be loaded. The files loaded are
assumed to contain a complete and correct HTTP response (lines that
-are part of the HTTP response line and headers must end wih CRLF).
+are part of the HTTP response line and headers must end with CRLF).
+
+=item B<-rev>
+
+simple test server which just reverses the text received from the client
+and sends it back to the server. Also sets B<-brief>.
=item B<-engine id>
-specifying an engine (by it's unique B<id> string) will cause B<s_server>
+specifying an engine (by its unique B<id> string) will cause B<s_server>
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
+=item B<-id_prefix arg>
+
+generate SSL/TLS session IDs prefixed by B<arg>. This is mostly useful
+for testing any SSL/TLS code (eg. proxies) that wish to deal with multiple
+servers, when each of which might be generating a unique range of session
+IDs (eg. with a certain prefix).
+
=item B<-rand file(s)>
a file or files containing random data used to seed the random number
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
all others.
+=item B<-serverinfo file>
+
+a file containing one or more blocks of PEM data. Each PEM block
+must encode a TLS ServerHello extension (2 bytes type, 2 bytes length,
+followed by "length" bytes of extension data). If the client sends
+an empty TLS ClientHello extension matching the type, the corresponding
+ServerHello extension will be returned.
+
+=item B<-no_resumption_on_reneg>
+
+set SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION flag.
+
+=item B<-status>
+
+enables certificate status request support (aka OCSP stapling).
+
+=item B<-status_verbose>
+
+enables certificate status request support (aka OCSP stapling) and gives
+a verbose printout of the OCSP response.
+
+=item B<-status_timeout nsec>
+
+sets the timeout for OCSP response to B<nsec> seconds.
+
+=item B<-status_url url>
+
+sets a fallback responder URL to use if no responder URL is present in the
+server certificate. Without this option an error is returned if the server
+certificate does not contain a responder address.
+
+=item B<-nextprotoneg protocols>
+
+enable Next Protocol Negotiation TLS extension and provide a
+comma-separated list of supported protocol names.
+The list should contain most wanted protocols first.
+Protocol names are printable ASCII strings, for example "http/1.1" or
+"spdy/3".
