rpcsvchost -- hosting environment for DCE/RPC services SYNOPSIS
rpcsvchost [options] service [service ...] DESCRIPTION
rpcsvchost is a very simple environment for hosting DCE/RPC services. It loads DCE/RPC services from the list of plugins given as arguments, binds to an appropriate set of endpoints and listens for protocol requests. If service is not a relative file name, it is assumed to be the name of a dylib located in /usr/lib/rpcsvc. OPTIONS
-debug, -nodebug rpcsvchost will log debug information and may perform extra diagnostic checks. This option is typically only useful for debugging. -endpoints BINDING [,BINDING] This argument specifies additional endpoints that rpcsvchost should attempt to bind. BINDING must be a comma-separated list of DCE/RPC binding strings that include both the protocol sequence and endpoint fields. -help Prints a usage message and exits. -launchd, -nolaunchd Normally, rpcsvchost attempts to bind all the well-known endpoints specified by the service plugins. If there are no well-known endpoints, it will bind new endpoints on all supported protocol sequences. The -launchd option disables this behavior and causes rpcsvchost to check in with launchd(8) to obtain a set of sockets to bind as protocol endpoints. Launchd sockets vended to rpcsvchost must be named with the appropriate DCE/RPC protocol sequence (eg. "ncacn_np"). -sandbox, -nosandbox When this option is specified, the modules loaded by rpcsvchost will be run in a sandbox. rpcsvchost will attempt to intialize the sandbox using the sandbox profile with the name<module-name>.sb. See sandbox(7) for an overview of the sandbox facility. -register, -noregister When this option is specified, rpcsvchost attempts to register the loaded services with the DCE/RPC endpoint mapper. -stdout Causes rpcsvchost to print log messages to standard output instead of the system log. -wait-for-debugger Causes rpcsvchost to wait for a debugger to attach after it has loaded and initialized its plugins. This is useful for debugging instances of rpcsvchost that are launched by launchd(8). DIAGNOSTICS
The rpcsvchost utility exits 0 on success, and >0 if an error occurs. SEE ALSO
launchd.plist(5), launchd(8), sandbox(7) HISTORY
The rpcsvchost utility first appeared in Mac OS 10.7. Darwin June 2, 2019 Darwin

rpcbind -- portmap SYNOPSIS
rpcbind [-d] [-v] [-h bindip] DESCRIPTION
Rpcbind is a server that converts RPC program numbers into DARPA protocol port numbers. It is a replacement for the older portmap program. rpcbind supports the original version 2 portmap protocol and in addition supports the newer version 3 and version 4 protocols that are neces- sary for IPv6 support. It must be running on the server in order to make RPC calls. When an RPC server is started, it will tell rpcbind what address it is listening to, and what RPC program numbers it is prepared to serve. When a client wishes to make an RPC call to a given program number, it will first contact rpcbind on the server machine to determine the address where RPC packets should be sent. rpcbind is a launchd service. When the first server tries to register with rpcbind the RPC library will contact launchd and arrange for rpcbind to be started. Note it is no longer possible to run rpcbind from the command line. rpcbind logs errors and information using asl(3). rpcbind uses hosts_access(5) for access control; note access control patterns may only reference IP addresses. The following options are available and will need to be added to the rpcbind plist file. -d causes rpcbind errors and debugging information to be printed to the standard error output via asl_log. This option is no longer very useful. -v Enable verbose logging of access control checks. -h Specify specific IP addresses to bind to for UDP requests. This option may be specified multiple times and is typically necessary when running on a multi-homed host. If no -h option is specified, rpcbind will bind to INADDR_ANY, which could lead to problems on a multi-homed host due to rpcbind returning a UDP packet from a different IP address than it was sent to. Note that when specifying IP addresses with -h, rpcbind will automatically add to the list. FILES
/System/Library/LaunchDaemons/ launchd.plist(5) file for rpcbind. Options should be added here. /usr/share/sandbox/ sandbox(7) file for rpcbind. SEE ALSO
hosts_access(5), launchd.plist(5), launchd(8), rpcinfo(8) BUGS
If rpcbind crashes, all servers must be restarted. Version 4 getstat procedure is not implemented and will always return 0 and null values. RPC_SYSTEMERROR. -h option is not supported for IPv6. Darwin May 31, 2019 Darwin
