myproxy-logon(1) MyProxy myproxy-logon(1)
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 Cer-
tificate 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 standard location (
/tmp/x509up_u<uid> ).
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, --pshost hostname
Specifies the hostname of the myproxy-server. This option is
required if the MYPROXY_SERVER environment variable is not
defined. If specified, this option overrides the MYPROXY_SERVER
environment variable.
-p port, --psport port
Specifies the TCP port number of the myproxy-server(8).
Default: 7512
-l, --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 creden-
tial 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 life-
time 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 default location ( /tmp/x509up_u<uid> ). 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 X509_USER_PROXY or X509_USER_CERT and
X509_USER_KEY 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 ~/.globus/certificates.
-q, --quiet
Only write output messages on error.
-N, --no_credentials
Authenticate only. Don't retrieve credentials.
-m voms, --voms voms
Include VOMS attributes in the retrieved credential. The VOMS
server name must be provided, as required by voms-proxy-init
-voms. The voms-proxy-init command must be installed and con-
figured to use this option.
EXIT STATUS
0 on success, >0 on error
ENVIRONMENT
MYPROXY_SERVER
Specifies the hostname where the myproxy-server(8) is running.
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 of the form "host/<fqhn>" or "myproxy/<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.
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.
