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 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 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 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 location specified by the X509_USER_PROXY environ-
ment 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 authenticat-
ing 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 pro-
tect against man-in-the-middle attacks. If, however, this
option is specified, myproxy-logon will accept the CA to boot-
strap 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 cer-
tificate 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 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.
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 speci-
fies 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 direc-
tory.
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.
