PROGRAM:
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.
