This is the command pmfind that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
pmfind - find PCP services on the network
SYNOPSIS
pmfind [-q] [-m mechanism] [-s service] [-r] [-t timeout]
DESCRIPTION
pmfind searches for instances of the specified PCP service being advertised on the network
and prints a list of URLs corresponding to the services discovered.
By default pmfind will search for all supported PCP services, however a specific PCP
service to discover can be specified using the -s option. Supported services are pmcd(1),
pmproxy(1) and pmwebd(1).
The -m option sets the mechanism that pmfind uses when performing service discovery. By
default, or if the keyword "all" is specified, every available mechanism will be used
(iteratively). Supported mechanisms are:
avahi Searches for services which are broadcasting using mDNS via avahi-daemon(8). An
optional suffix ",timeout=N" may be added to limit the amount of time waiting for
the avahi-daemon. N is a floating point number specifying the number of seconds to
wait. The default is 0.5 seconds. This timeout may also be specified by setting
the environment variable AVAHI_DISCOVERY_TIMEOUT to the desired number of seconds.
If both are specified, then the value specified in the environment variable takes
precedence.
probe=<net-address>/<mask-bits>
Actively probes the given subnet for the requested PCP service(s). <net-address>
is an inet or ipv6 network address and <mask-bits> is the number of bits used to
define the subnet. For example, 192.168.1.0/24 defines an 8 bit subnet consisting
of the addresses 192.168.1.0 through 192.168.1.255. An optional suffix
",maxThreads=N" may be added to limit the number of threads used while probing. The
default is the value of FD_SETSIZE or the number of addresses in the subnet,
whichever is less. An optional suffix ",timeout=N" may be added to limit the
amount of time waiting for each connection attempt. N is a floating point number
specifying the number of seconds to wait. The default is 20ms.
The -r option requests that DNS name resolution be attempted for the addresses of any
discovered services. The default is to display the network addresses of any discovered
services.
The -t option sets the maximum amount of time that pmfind will take before interrupting
the service discovery. The argument is a floating point number representing the number of
seconds before timing out. The default is to take as much time as is needed to complete
the process.
The -q option suppresses all output on the standard output stream.
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory
names used by PCP. On each installation, the file /etc/pcp.conf contains the local values
for these variables. The $PCP_CONF variable may be used to specify an alternative
configuration file, as described in pcp.conf(5).
DIAGNOSTICS
The value of the exit status from the command is zero when services were successfully
located, one if no services were found, and two if an error occurred.
In the event of an error, a message will be generated on standard error that is intended
to be self-explanatory.
SIGNALS
pmfind will interrupt the service discovery process when one of the following signals is
received: SIGHUP, SIGPIPE, SIGINT, SIGTERM, SIGXFSZ, SIGXCPU. pmfind will report any
results which were discovered up to point of the interruption.
