condor_ping — HTCondor Manual

Attempt a security negotiation to determine if it succeeds
 

condor_ping [-help | -version ]

condor_ping [-debug ] [-address <a.b.c.d:port>] [-pool host name] [-name daemon name] [-type subsystem] [-config filename] [-quiet | -table | -verbose | -long | -format | -af ] token [token [...] ]

condor_ping attempts a security negotiation to discover whether the configuration is set such that the negotiation succeeds. The target of the negotiation is defined by one or a combination of the address, pool, name, or type options. If no target is specified, the default target is the condor_schedd daemon on the local machine.

One or more token s may be listed, thereby specifying one or more authorization level to impersonate in security negotiation. A token is the value ALL, an authorization level, a command name, or the integer value of a command. The many command names and their associated integer values will more likely be used by experts, and they are defined in the file condor_includes/condor_commands.h.

An authorization level may be one of the following strings. If ALL is listed, then negotiation is attempted for each of these possible authorization levels. Note that OWNER is no longer used in HTCondor, but is kept here for use when talking to older daemons (prior to 9.9.0).

-help

Display usage information

-version

Display version information

-debug

Print extra debugging information as the command executes.

-config filename

Attempt the negotiation based on the contents of the configuration file contents in file filename.

-address <a.b.c.d:port>

Target the given IP address with the negotiation attempt.

-pool hostname

Target the given host with the negotiation attempt. May be combined with specifications defined by name and type options.

-name daemonname

Target the daemon given by daemonname with the negotiation attempt.

-type subsystem

Target the daemon identified by subsystem, one of the values of the predefined $(SUBSYSTEM) macro.

-quiet

Set exit status only; no output displayed.

-table

Output is displayed with one result per line, in a table format.

-verbose

Display all available output.

-long

Display result classads.

-format fmt attr

(Custom option) Display attribute or expression attr in format fmt. To display the attribute or expression the format must contain a single printf(3)-style conversion specifier. Attributes must be from the resource ClassAd. Expressions are ClassAd expressions and may refer to attributes in the resource ClassAd. If the attribute is not present in a given ClassAd and cannot be parsed as an expression, then the format option will be silently skipped. %r prints the unevaluated, or raw values. The conversion specifier must match the type of the attribute or expression. %s is suitable for strings such as Name, %d for integers such as LastHeardFrom, and %f for floating point numbers such as LoadAvg. %v identifies the type of the attribute, and then prints the value in an appropriate format. %V identifies the type of the attribute, and then prints the value in an appropriate format as it would appear in the -long format. As an example, strings used with %V will have quote marks. An incorrect format will result in undefined behavior. Do not use more than one conversion specifier in a given format. More than one conversion specifier will result in undefined behavior. To output multiple attributes repeat the -format option once for each desired attribute. Like printf(3)-style formats, one may include other text that will be reproduced directly. A format without any conversion specifiers may be specified, but an attribute is still required. Include a backslash followed by an 'n' to specify a line break.

-autoformat[:lhVr,tng] attr1 [attr2 ...] or -af[:lhVr,tng] attr1 [attr2 ...]

(Output option) Display attribute(s) or expression(s) formatted in a default way according to attribute types. This option takes an arbitrary number of attribute names as arguments, and prints out their values, with a space between each value and a newline character after the last value. It is like the -format option without format strings. This output option does not work in conjunction with the -run option.

It is assumed that no attribute names begin with a dash character, so that the next word that begins with dash is the start of the next option. The autoformat option may be followed by a colon character and formatting qualifiers to deviate the output formatting from the default:

l label each field,

h print column headings before the first line of output,

V use %V rather than %v for formatting (string values are quoted),

r print "raw", or unevaluated values,

, add a comma character after each field,

t add a tab character before each field instead of the default space character,

n add a newline character after each field,

g add a newline character between ClassAds, and suppress spaces before each field.

Use -af:h to get tabular values with headings.

Use -af:lrng to get -long equivalent format.

The newline and comma characters may not be used together. The l and h characters may not be used together.

The example Unix command

$ condor_ping  -address "<127.0.0.1:9618>" -table READ WRITE DAEMON

places double quote marks around the sinful string to prevent the less than and the greater than characters from causing redirect of input and output. The given IP address is targeted with 3 attempts to negotiate: one at the READ authorization level, one at the WRITE authorization level, and one at the DAEMON authorization level.

condor_ping will exit with the status value of the negotiation it attempted, where 0 (zero) indicates success, and 1 (one) indicates failure. If multiple security negotiations were attempted, the exit status will be the logical OR of all values.
