NAME

grid-cert-diagnostics - Print diagnostic information about certificates and keys

SYNOPSIS

grid-cert-diagnostics [ -h | -help ]

grid-cert-diagnostics [ -p ] [ -n ] [ -c CERTIFICATE [-H HOSTNAME] [-m { STRICT_GT2 | HYBRID | STRICT_RFC2818 }]]

grid-cert-diagnostics [ -s HOST[:PORT] | -g HOST[:PORT] ] [-m { STRICT_GT2 | HYBRID | STRICT_RFC2818 }]

DESCRIPTION

The grid-cert-diagnostics program displays information about the current user's security environment, including information about security-related environment variables, security directory search path, personal key and certificates, and trusted certificates. It is intended to provide information to help diagnose problems using GSIC.

By default, grid-cert-diagnostics prints out information regarding the environment and trusted certificate directory. If the -p command-line option is used, then additional information about the current user's default certificate and key will be printed.

The grid-cert-diagnostics program can also attempt do diagnose problems connecting to remote GridFTP or SSL-based services.

OPTIONS

The full set of command-line options to grid-cert-diagnostics consists of:

-h, -help

: Display a help message and exit.

-p

: Display information about the personal certificate and key that is the current user's default credential.

-n

: Check time synchronization with the ntpdate command.

-c CERTIFICATE, -c -

: Check the validity of the certificate in the file named by CERTIFICATE or standard input if the parameter to -c is -.

-H HOSTNAME

: When using the -c option above, check that the certificate's identity matches HOSTNAME.

-m STRICT_GT2 | HYBRID | STRICT_RFC2818

: Use the specified mode when comparing host certificate names.

-s HOST[:PORT]

: Connect to the service listening on HOST:PORT and initiate the TLS protocol. Diagnostics will be printed containing the TLS / SSL protocol version and available cipher list. The certificate chain will be verified, and certificate subject name, issuer name, and subjectAltName extensions will be printed. If the :PORT is omitted, the default of 443 is used.

-g HOST[:PORT]

: Similar to the -s option, but use the GridFTP protocol. The initial GridFTP banner response is included in the diagnostic output. If the :PORT is omitted, the default of 2811 is used.

EXAMPLES

In this example, we see the default mode of checking the default security environment for the system, without processing the user's key and certificate. Note the user receives a warning about a cog.properties and about an expired CA certificate.
