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 host-
name, 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 LOG-
NAME environment variable. Use this option to specify a differ-
ent account username on the MyProxy server. The MyProxy user-
name 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 verify-
ing 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 per-
formed 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 run-
ning. 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 direc-
tory.
