PROGRAM:

NAME

myproxy-change-pass-phrase - change MyProxy passphrase

SYNOPSIS

myproxy-change-pass-phrase [ options ]

DESCRIPTION

The myproxy-change-pass-phrase command changes the passphrase under which a credential is
protected in the MyProxy repository. The command first prompts for the current passphrase
for the credential, then prompts twice for the new passphrase. Only the credential owner
can change a credential's passphrase. The user must have a valid proxy credential as
generated by grid-proxy-init or retrieved by myproxy-logon(1) when running this command.

OPTIONS

-h, --help
Displays command usage text and exits.

-u, --usage
Displays command usage text and exits.

-v, --verbose
Enables verbose debugging output to the terminal.

-V, --version
Displays version information and exits.

-s hostname[:port], --pshost hostname[:port]
Specifies the hostname(s) of the myproxy-server(s). Multiple hostnames, each
hostname optionally followed by a ':' and port number, may be specified in a comma-
separated list. This option is required if the MYPROXY_SERVER environment variable
is not defined. If specified, this option overrides the MYPROXY_SERVER environment
variable. If a port number is specified with a hostname, it will override the -p
option as well as the MYPROXY_SERVER_PORT environment variable for that host.

-p port, --psport port
Specifies the TCP port number of the myproxy-server(8). Default: 7512

-l username, --username username
Specifies the MyProxy account under which the credential should be stored. By
default, the command uses the value of the LOGNAME environment variable. Use this
option to specify a different account username on the MyProxy server. The MyProxy
username need not correspond to a real Unix username.

-d, --dn_as_username
Use the certificate subject (DN) as the default username, instead of the LOGNAME
environment variable.

-k name, --credname name
Specifies the credential name.

-S, --stdin_pass
By default, the command prompts for a passphrase and reads the passphrase from the
active tty. When running the command non-interactively, there may be no associated
tty. Specifying this option tells the command to read passphrases from standard
input without prompts or confirmation.

EXIT STATUS

0 on success, >0 on error

ENVIRONMENT

GLOBUS_GSSAPI_NAME_COMPATIBILITY
This client will, by default, perform a reverse-DNS lookup to determine the FQHN
(Fully Qualified Host Name) to use in verifying the identity of the server by
checking the FQHN against the CN in server's certificate. Setting this variable to
STRICT_RFC2818 will cause the reverse-DNS lookup to NOT be performed and the user-
specified name to be used instead. This variable setting will be ignored if
MYPROXY_SERVER_DN (described later) is set.

MYPROXY_SERVER
Specifies the hostname(s) where the myproxy-server(8) is running. Multiple
hostnames can be specified in a comma separated list with each hostname optionally
followed by a ':' and port number. This environment variable can be used in place
of the -s option.

MYPROXY_SERVER_PORT
Specifies the port where the myproxy-server(8) is running. This environment
variable can be used in place of the -p option.

MYPROXY_SERVER_DN
Specifies the distinguished name (DN) of the myproxy-server(8). All MyProxy client
programs authenticate the server's identity. By default, the MyProxy client
programs expect the server to have a distinguished name with "/CN=host/<fqhn>" or
"/CN=myproxy/<fqhn>" or "/CN=<fqhn>" (where <fqhn> is the fully-qualified hostname
of the server). If the server is running with some other DN, you can set this
environment variable to tell the MyProxy clients to accept the alternative DN. Also
see GLOBUS_GSSAPI_NAME_COMPATIBILITY above.

MYPROXY_TCP_PORT_RANGE
Specifies a range of valid port numbers in the form "min,max" for the client side
of the network connection to the server. By default, the client will bind to any
available port. Use this environment variable to restrict the ports used to a
range allowed by your firewall. If unset, MyProxy will follow the setting of the
GLOBUS_TCP_PORT_RANGE environment variable.

X509_USER_CERT
Specifies a non-standard location for the certificate to be used for authentication
to the myproxy-server(8).

X509_USER_KEY
Specifies a non-standard location for the private key to be used for authentication
to the myproxy-server(8).

X509_USER_PROXY
Specifies a non-standard location for the proxy credential to be used for
authentication to the myproxy-server(8).

X509_CERT_DIR
Specifies a non-standard location for the CA certificates directory.
