myproxy-change-pass-phrase(1)
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.
