Ubuntu Manpage: myproxy-init - store a credential for later retrieval

NAME

       myproxy-init - store a credential for later retrieval

SYNOPSIS

       myproxy-init [ options ]

DESCRIPTION

The myproxy-init command uploads a credential to a myproxy-server(8) for later retrieval.
In the default mode, the command first prompts for the user's Grid pass phrase (if
needed), which is used to create a proxy credential. The command then prompts for a
MyProxy pass phrase, which will be required to later retrieve the credential. The MyProxy
pass phrase must be entered a second time for confirmation. A credential with a lifetime
of one week (by default) is then delegated to the myproxy-server(8) and stored with the
given MyProxy pass phrase. Proxy credentials with default lifetime of 12 hours can then
be retrieved by myproxy-logon(1) using the MyProxy passphrase. The default behavior can
be overridden by options specified below.

The myproxy-init command can also upload a credential to a myproxy-server(8) to support
credential renewal. Renewal allows a trusted service (for example, a batch job scheduler)
to obtain a new credential for a user before the existing credential it has for that user
expires. The -R argument to myproxy-init configures the credential for renewal by the
specified service. Renewal requires two authentications. The renewing service must
authenticate with its own credentials, matching the distinquished name specified by the -R
argument, and must also authenticate with an existing credential that matches the
distinguished name of the stored credential, to retrieve a new credential.

A credential may be used either for retrieval or renewal but not both. If both are
desired, upload a different credential for each use, with a different name using the -k
option.

The hostname where the myproxy-server(8) is running must be specified by either defining
the MYPROXY_SERVER environment variable or the -s option.

By default, myproxy-init will create a proxy credential from the user's end-entity
credentials at ~/.globus/usercert.pem and ~/.globus/userkey.pem to delegate to the
myproxy-server(8). To specify an alternate location for the source certificate and key to
delegate, use the X509_USER_CERT and X509_USER_KEY environment variables. To use a proxy
credential as the source of the delegation, set both environment variables to the location
of the proxy credential. To delegate a "legacy globus proxy", set the GT_PROXY_MODE
environment variable to "old". To delegate an "RFC 3820 compliant proxy", set the
GT_PROXY_MODE environment variable to "rfc".

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.

-c hours, --cred_lifetime hours
Specifies the lifetime of the credential stored on the myproxy-server(8) in hours.
Specify 0 for the maximum possible lifetime, i.e., the lifetime of the original
credential. Default: 1 week (168 hours)

-t hours, --proxy_lifetime hours
Specifies the maximum lifetime of credentials retrieved from the myproxy-server(8)
using the stored credential. Default: 12 hours

-C filename, --certfile filename
Specifies the filename of the source certificate.

-y filename, --keyfile filename
Specifies the filename of the source private key.

-d, --dn_as_username
Use the certificate subject (DN) as the default username, instead of the LOGNAME
environment variable.

-a, --allow_anonymous_retrievers
Allow credentials to be retrieved with just pass phrase authentication. By
default, only entities with credentials that match the myproxy-server.config(5)
default retriever policy may retrieve credentials. This option allows entities
without existing credentials to retrieve a credential using pass phrase
authentication by including "anonymous" in the set of allowed retrievers. The
myproxy-server.config(5) server-wide policy must also allow "anonymous" clients for
this option to have an effect.

-A, --allow_anonymous_renewers
Allow credentials to be renewed by any client. Any client with a valid credential
with a subject name that matches the stored credential may retrieve a new
credential from the MyProxy repository if this option is given. Since this
effectively defeats the purpose of proxy credential lifetimes, it is not
recommended. It is included only for sake of completeness.

-r name, --retrievable_by name
Allow the specified entity to retrieve credentials. See -x and -X options for
controlling name matching behavior.

-R name, --renewable_by name
Allow the specified entity to renew credentials. See -x and -X options for
controlling name matching behavior. This option implies -n since passphrase
authentication is not used for credential renewal.

-Z name, --retrievable_by_cert name
Allow the specified entity to retrieve credentials without a passphrase. See -x
and -X options for controlling name matching behavior. This option implies -n.

-x, --regex_dn_match
Specifies that names used with following options -r, -R, and -Z will be matched
against the full certificate subject distinguished name (DN) according to REGULAR
EXPRESSIONS in myproxy-server.config(5).

-X, --match_cn_only
Specifies that names used with following options -r, -R, and -Z will be matched
against the certificate subject common name (CN) according to REGULAR EXPRESSIONS
in myproxy-server.config(5). For example, if an argument of -r "Jim Basney" is
specified, then the resulting policy will be "*/CN=Jim Basney". This is the
default behavior.

-k name, --credname name
Specifies the credential name.

-K description, --creddesc description
Specifies credential description.

-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.

-L, --local_proxy
In addition to storing a proxy credential on the myproxy-server(8) with lifetime
set by --cred_lifetime (default 1 week), create a local proxy credential with
lifetime set by --proxy_lifetime (default 12 hours).

-n, --no_passphrase
Don't prompt for a credential passphrase. Store credentials without a credential
passphrase, to be protected by other methods, such as PAM, SASL, or certificate-
based authentication. This option is implied by -R since passphrase authentication
is not used for credential renewal. Note that the myproxy-server(8) always
requires some type of authentication for retrieving credentials, so if you store a
credential with no passphrase and other authentication methods are not configured,
the credential will not be accessible.

-m voms, --voms voms
Add VOMS attributes to the credential by running voms-proxy-init on the client-side
before storing the credential on the myproxy-server(8). The VOMS VO name must be
provided, as required by voms-proxy-init -voms. The voms-proxy-init command must
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 correctly.

EXIT STATUS

       0 on success, >0 on error

FILES

       ~/.globus/usercert.pem
              Default  location  of  the  certificate from which the proxy credential is created.
              Set the X509_USER_CERT environment variable to override.

       ~/.globus/userkey.pem
              Default location of the private key from which the  proxy  credential  is  created.
              Set the X509_USER_KEY environment variable to override.

       /tmp/myproxy-proxy.<uid>.<pid>
              Location  of  the  temporary  proxy  credential  that  is delegated to the myproxy-
              server(8).  It is removed after the delegation is completed.

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, 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
              GLOBUS_GSSAPI_NAME_COMPATIBILITY above.

       X509_USER_CERT
              Specifies a  non-standard  location  for  the  certificate  from  which  the  proxy
              credential  is  created.  The location may be the path to an end-entity certificate
              (ex.  ~/.globus/usercert.pem) or a proxy (ex.  /tmp/x509up_u<uid>).

       X509_USER_KEY
              Specifies a non-standard  location  for  the  private  key  from  which  the  proxy
              credential  is  created.  The location may be the path to an end-entity private key
              (ex.  ~/.globus/userkey.pem) or a proxy (ex.  /tmp/x509up_u<uid>).

       X509_CERT_DIR
              Specifies a non-standard location for the CA certificates directory.

       GT_PROXY_MODE
              Set to "old" to store a "legacy globus proxy" in the MyProxy  repository.   Set  to
              "rfc" to store an "RFC 3820 compliant proxy" in the MyProxy repository.

       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.

       MYPROXY_KEYBITS
              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.
