It is a \fIvery\fR useful diagnostic tool for -\&\s-1SSL\s0 servers. -.SH "OPTIONS" -.IX Header "OPTIONS" -.Ip "\fB\-connect host:port\fR" 4 -.IX Item "-connect host:port" -This specifies the host and optional port to connect to. If not specified -then an attempt is made to connect to the local host on port 4433. -.Ip "\fB\-cert certname\fR" 4 -.IX Item "-cert certname" -The certificate to use, if one is requested by the server. The default is -not to use a certificate. -.Ip "\fB\-key keyfile\fR" 4 -.IX Item "-key keyfile" -The private key to use. If not specified then the certificate file will -be used. -.Ip "\fB\-verify depth\fR" 4 -.IX Item "-verify 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. -.Ip "\fB\-CApath directory\fR" 4 -.IX Item "-CApath directory" -The directory to use for server certificate verification. This directory -must be in \*(L"hash format\*(R", see \fBverify\fR for more information. These are -also used when building the client certificate chain. -.Ip "\fB\-CAfile file\fR" 4 -.IX Item "-CAfile file" -A file containing trusted certificates to use during server authentication -and to use when attempting to build the client certificate chain. -.Ip "\fB\-reconnect\fR" 4 -.IX Item "-reconnect" -reconnects to the same server 5 times using the same session \s-1ID\s0, this can -be used as a test that session caching is working. -.Ip "\fB\-pause\fR" 4 -.IX Item "-pause" -pauses 1 second between each read and write call. -.Ip "\fB\-showcerts\fR" 4 -.IX Item "-showcerts" -display the whole server certificate chain: normally only the server -certificate itself is displayed. -.Ip "\fB\-prexit\fR" 4 -.IX Item "-prexit" -print session information when the program exits. This will always attempt -to print out information even if the connection fails. Normally information -will only be printed out once if the connection succeeds. This option is useful -because the cipher in use may be renegotiated or the connection may fail -because a client certificate is required or is requested only after an -attempt is made to access a certain \s-1URL\s0. Note: the output produced by this -option is not always accurate because a connection might never have been -established. -.Ip "\fB\-state\fR" 4 -.IX Item "-state" -prints out the \s-1SSL\s0 session states. -.Ip "\fB\-debug\fR" 4 -.IX Item "-debug" -print extensive debugging information including a hex dump of all traffic. -.Ip "\fB\-nbio_test\fR" 4 -.IX Item "-nbio_test" -tests non-blocking I/O -.Ip "\fB\-nbio\fR" 4 -.IX Item "-nbio" -turns on non-blocking I/O -.Ip "\fB\-crlf\fR" 4 -.IX Item "-crlf" -this option translated a line feed from the terminal into \s-1CR+LF\s0 as required -by some servers. -.Ip "\fB\-ign_eof\fR" 4 -.IX Item "-ign_eof" -inhibit shutting down the connection when end of file is reached in the -input. -.Ip "\fB\-quiet\fR" 4 -.IX Item "-quiet" -inhibit printing of session and certificate information. This implicitely -turns on \fB\-ign_eof\fR as well. -.Ip "\fB\-ssl2\fR, \fB\-ssl3\fR, \fB\-tls1\fR, \fB\-no_ssl2\fR, \fB\-no_ssl3\fR, \fB\-no_tls1\fR" 4 -.IX Item "-ssl2, -ssl3, -tls1, -no_ssl2, -no_ssl3, -no_tls1" -these options disable the use of certain \s-1SSL\s0 or \s-1TLS\s0 protocols. By default -the initial handshake uses a method which should be compatible with all -servers and permit them to use \s-1SSL\s0 v3, \s-1SSL\s0 v2 or \s-1TLS\s0 as appropriate. -.Sp -Unfortunately there are a lot of ancient and broken servers in use which -cannot handle this technique and will fail to connect. Some servers only -work if \s-1TLS\s0 is turned off with the \fB\-no_tls\fR option others will only -support \s-1SSL\s0 v2 and may need the \fB\-ssl2\fR option. -.Ip "\fB\-bugs\fR" 4 -.IX Item "-bugs" -there are several known bug in \s-1SSL\s0 and \s-1TLS\s0 implementations. Adding this -option enables various workarounds. -.Ip "\fB\-cipher cipherlist\fR" 4 -.IX Item "-cipher cipherlist" -this allows the cipher list sent by the client to be modified. Although -the server determines which cipher suite is used it should take the first -supported cipher in the list sent by the client. See the \fBciphers\fR -command for more information. -.Ip "\fB\-rand \f(BIfile\fB\|(s)\fR" 4 -.IX Item "-rand file" -a file or files containing random data used to seed the random number -generator, or an \s-1EGD\s0 socket (see RAND_egd(3)). -Multiple files can be specified separated by a OS-dependent character. -The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for -all others. -.SH "CONNECTED COMMANDS" -.IX Header "CONNECTED COMMANDS" -If a connection is established with an \s-1SSL\s0 server then any data received -from the server is displayed and any key presses will be sent to the -server. When used interactively (which means neither \fB\-quiet\fR nor \fB\-ign_eof\fR -have been given), the session will be renegociated if the line begins with an -\&\fBR\fR, and if the line begins with a \fBQ\fR or if end of file is reached, the -connection will be closed down. -.SH "NOTES" -.IX Header "NOTES" -\&\fBs_client\fR can be used to debug \s-1SSL\s0 servers. To connect to an \s-1SSL\s0 \s-1HTTP\s0 -server the command: -.PP -.Vb 1 -\& openssl s_client -connect servername:443 -.Ve -would typically be used (https uses port 443). If the connection succeeds -then an \s-1HTTP\s0 command can be given such as \*(L"\s-1GET\s0 /\*(R" to retrieve a web page. -.PP -If the handshake fails then there are several possible causes, if it is -nothing obvious like no client certificate then the \fB\-bugs\fR, \fB\-ssl2\fR, -\&\fB\-ssl3\fR, \fB\-tls1\fR, \fB\-no_ssl2\fR, \fB\-no_ssl3\fR, \fB\-no_tls1\fR can be tried -in case it is a buggy server. In particular you should play with these -options \fBbefore\fR submitting a bug report to an OpenSSL mailing list. -.PP -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 \*(L"acceptable \s-1CA\s0 list\*(R" when it -requests a certificate. By using \fBs_client\fR the \s-1CA\s0 list can be viewed -and checked. However some servers only request client authentication -after a specific \s-1URL\s0 is requested. To obtain the list in this case it -is necessary to use the \fB\-prexit\fR command and send an \s-1HTTP\s0 request -for an appropriate page. -.PP -If a certificate is specified on the command line using the \fB\-cert\fR -option it will not be used unless the server specifically requests -a client certificate. Therefor merely including a client certificate -on the command line is no guarantee that the certificate works. -.PP -If there are problems verifying a server certificate then the -\&\fB\-showcerts\fR option can be used to show the whole chain. -.SH "BUGS" -.IX Header "BUGS" -Because this program has a lot of options and also because some of -the techniques used are rather old, the C source of s_client is rather -hard to read and not a model of how things should be done. A typical -\&\s-1SSL\s0 client program would be much simpler. -.PP -The \fB\-verify\fR option should really exit if the server verification -fails. -.PP -The \fB\-prexit\fR option is a bit of a hack. We should really report -information whenever a session is renegotiated. -.SH "SEE ALSO" -.IX Header "SEE ALSO" -sess_id(1), s_server(1), ciphers(1) |
