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.
