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.
