tpafd - service discovery server
tpafd [options...] [domain-addr...]
tpafd is a server for use in a Pathfinder light-weight service discovery system.
tpafd is designed to be used as a daemon (i.e., a UNIX server process), but does not daemonize itself (e.g., it does not call fork() and runs in the background).
tpafd must be supplied one or more arguments, where each argument is a server socket address (in XCM format).
For each address, the server will instantiate a service discovery domain, and bind to the socket. Thus, a server process may be used to serve more than one service discovery domain.
-s
Enable logging to console (standard error). Console logging is
disabled by default.
-y <facility>
Set syslog facility to use. For example, -y local0 will make pafd
set the facility to LOG_LOCAL0 on all log messages.
-n
Disable logging to syslog. Syslog logging is enabled by default.
-l <level>
Discard log messages with a severity level below level. For example,
-l notice will filter out any log message a level lower than
LOG_NOTICE (i.e., LOG_INFO and LOG_DEBUG).
-v
Display tpafd version information and exit.
-h
Display tpafd usage information and exit.
Options override any configuration set by a configuration file.
The below example spawns one server process with two service discovery domains; one on a UNIX domain socket "foo", and one answering on TCP port 4711:
$ tpafd ux:foo tcp:*:4711
This example spawns a server process, instantiates one domain, and enables console logging and disables log filtering:
$ tpafd -s -l debug ux:fo
tpafd[126513]: tpafd version 0.0.1 started.
tpafd[126513]: Configured domain bound to "ux:foo".
tpafd[126513]: Started serving domain.
