       myproxy-logon - retrieve a credential


       myproxy-logon [ options ]

       myproxy-get-delegation [ options ]


       The myproxy-logon command retrieves a proxy credential from the myproxy-server(8) that was
       previously stored using myproxy-init(1) or myproxy-store(1).   It  can  also  be  used  to
       retrieve  short-lived end entity credentials from a myproxy-server(8) configured to act as
       a Certificate Authority.  In the default mode, the command prompts for  the  MyProxy  pass
       phrase  associated with the credential to be retrieved and stores the retrieved credential
       in   the   location   specified   by   the   X509_USER_PROXY   environment   variable   or
       /tmp/x509up_u<uid> if that environment variable is not set.

       The  myproxy-logon  command  is  also  available under the name myproxy-get-delegation for
       backward compatibility.


       -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 to retrieve is 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.  When used with the -a option, the certificate subject of the
              authorization credential is  used.   Otherwise,  the  certificate  subject  of  the
              default credential is used.

       -t hours, --proxy_lifetime hours
              Specifies  the  lifetime  of credentials retrieved from the myproxy-server(8) using
              the stored credential.  The resulting lifetime is  the  shorter  of  the  requested
              lifetime  and  the lifetime specified when the credential was stored using myproxy-
              init(1).  Default: 12 hours

       -o file, --out file
              Specifies where the retrieved proxy credential should be stored.  If this option is
              not specified, the proxy credential will be stored in the location specified by the
              X509_USER_PROXY environment variable  or  /tmp/x509up_u<uid>  if  that  environment
              variable  is  not  set.   To  write the credential to the command's standard output
              rather than to a file, use -o -.

       -a file, --authorization file
              Use this option to specify an existing, valid credential that you  want  to  renew.
              Renewing  a  credential  generally  requires two certificate-based authentications.
              The client authenticates with its identity, using the credential  in  the  standard
              location  or  specified  by the X509_USER_PROXY or X509_USER_CERT and X509_USER_KEY
              environment variables in addition to authenticating with the  existing  credential,
              in the location specified by this option, that it wants to renew.

       -k name, --credname name
              Specifies the name of the credential that is to be retrieved or renewed.

       -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.

       -n, --no_passphrase
              Don't prompt for a credential passphrase.  Use other  methods  for  authentication,
              such  as  Kerberos ticket or X.509 certificate.  This option is implied by -a since
              passphrase authentication is not used for credential renewal.

       -T, --trustroots
              Retrieve CA certificates directory from server  (if  available)  to  store  in  the
              location  specified  by the X509_CERT_DIR environment variable if set or /etc/grid-
              security/certificates if running as root or ~/.globus/certificates  if  running  as

       -b, --bootstrap
              Unless  this  option is specified, then if the X509_CERT_DIR exists and the CA that
              signed the myproxy-server(8) certificate is not trusted,  myproxy-logon  will  fail
              with  an  error,  to  protect against man-in-the-middle attacks.  If, however, this
              option is specified, myproxy-logon will accept the CA  to  bootstrap  trust.   This
              option implies -T.

       -q, --quiet
              Only write output messages on error.

       -N, --no_credentials
              Authenticate only.  Don't retrieve credentials.

       -m voms, --voms voms
              Add VOMS attributes to the credential by running voms-proxy-init on the client-side
              after retrieving the credential from the myproxy-server(8).  The VOMS VO name  must
              be  provided,  as  required  by voms-proxy-init -voms.  The voms-proxy-init command
              must also be installed and  configured  to  use  this  option.   For  example,  the
              VOMS_USERCONF  environment  variable  may need to be set for voms-proxy-init to run

       -Q file, --certreq file
              Specify the path to a PEM formatted certificate request to use  when  requesting  a
              certificate  from  the  myproxy-server(8),  rather  than  allowing myproxy-logon to
              generate the private key and certificate request itself.  In  this  case,  myproxy-
              logon will not output a private key but will only output the signed certificate and
              (as needed) certificate chain.  To read the certificate request from standard input
              rather than from a file, use -Q -.


       0 on success, >0 on error


              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.

              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.

              Specifies  the  port  where  the  myproxy-server(8)  is  running.  This environment
              variable can be used in place of the -p option.

              Specifies the distinguished name (DN) of the myproxy-server(8).  All MyProxy client
              programs  authenticate the server's identity.  By default, MyProxy servers run with
              host credentials, so 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

              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.

              Specifies a non-standard location for the certificate to be used for authentication
              to the myproxy-server(8).

              Specifies a non-standard location for the private key to be used for authentication
              to the myproxy-server(8).

              Specifies  a  non-standard  location  for  the  proxy  credential  to  be  used for
              authentication to the myproxy-server(8).  Also specifies the  output  location  for
              the  proxy  credential  to  be  retrieved  from the myproxy-server(8) unless the -o
              option is given.

              Specifies a non-standard location for the CA certificates directory.

              Specifies the size  for  RSA  keys  generated  by  MyProxy.   By  default,  MyProxy
              generates  2048 bit RSA keys.  Set this environment variable to "1024" for 1024 bit
              RSA keys.
