The s_time 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.
OPTIONS
-help
Print out a usage message.
-connect host:port
This specifies the host and optional port to connect to.
-www page
This specifies the page to GET from the server. A value of '/' gets the index.htm[l] page. If this parameter is not specified, then s_time will only perform the handshake to establish SSL connections but not transfer any payload data.
-cert 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.
-key keyfile
The private key to use. If not specified then the certificate file will be used. The file is in PEM format.
-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.
-CApath directory
The directory to use for server certificate verification. This directory must be in "hash format", see verify for more information. These are also used when building the client certificate chain.
-CAfile file
A file containing trusted certificates to use during server authentication and to use when attempting to build the client certificate chain.
-no-CAfile
Do not load the trusted CA certificates from the default file location
-no-CApath
Do not load the trusted CA certificates from the default directory location
-new
performs the timing test using a new session ID for each connection. If neither -new nor -reuse are specified, they are both on by default and executed in sequence.
-reuse
performs the timing test using the same session ID; this can be used as a test that session caching is working. If neither -new nor -reuse are specified, they are both on by default and executed in sequence.
-nbio
turns on non-blocking I/O.
-ssl3
these options disable the use of certain SSL or TLS protocols. By default the initial handshake uses a method which should be compatible with all servers and permit them to use SSL v3 or TLS as appropriate. The timing program is not as rich in options to turn protocols on and off as the -bugs
would typically be used (https uses port 443). 'commoncipher' is a cipher to which both client and server can agree, see the 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 -prexit option of BUGS
