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 creden-
tial 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 ser-
vice (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 environ-
ment 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 host-
name, 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 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.
-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 life-
time, 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 authen-
tication. 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 repos-
itory if this option is given. Since this effectively defeats
the purpose of proxy credential lifetimes, it is not recom-
mended. 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 cre-
dential 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 distin-
guished 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 meth-
ods, 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 creden-
tial is created. Set the X509_USER_CERT environment variable to
override.
~/.globus/userkey.pem
Default location of the private key from which the proxy creden-
tial 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 verify-
ing 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 per-
formed 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 run-
ning. 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 distin-
guished 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_COMPATI-
BILITY 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 direc-
tory.
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 environ-
ment variable to "1024" for 1024 bit RSA keys.
