The gss-client example takes this form on the command line:
gss-client [–port port] [–d] [–mech mech] host service-name [–f] msg
port – The port number for making the connection to the remote machine that is specified by host.
–d flag – Causes security credentials to be delegated to the server. Specifically, the deleg-flag variable is set to the GSS-API value GSS_C_DELEG_FLAG. Otherwise, deleg-flag is set to zero.
mech – The name of the security mechanism, such as Kerberos v5 to be used. If no mechanism is specified, the GSS-API uses a default mechanism.
host – The name of the server.
service-name – The name of the network service requested by the client. Some typical examples are the telnet, ftp, and login services.
msg – The string to send to the server as protected data. If the –f option is specified, then msg is the name of a file from which to read the string.
A typical command line for client application program might look like the following example:
% gss-client -port 8080 -d -mech kerberos_v5 erebos.eng nfs "ls"
The following example does not specify a mechanism, port, or delegation:
% gss-client erebos.eng nfs "ls"
