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, --pshost hostname
              Specifies  the  hostname(s)  of the myproxy-server(s).  Multiple
              hostnames 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.

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

       -l, --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

       MYPROXY_SERVER
              Specifies  the  hostname(s)  where the myproxy-server(8) is run-
              ning.  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.

       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.
