Ubuntu Manpage: myproxy-logon - retrieve a credential

NAME

       myproxy-logon - retrieve a credential

SYNOPSIS

       myproxy-logon [ options ]

       myproxy-get-delegation [ options ]

DESCRIPTION

       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.

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 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 non-root.

-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 correctly.

-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 -.

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, 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.

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

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

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.
