i have a client TCP and a Server TCP. i have used bind() only on the server, the port of socket client is given by the OS that's it ?
it retrieves this port from this range (/proc/sys/net/ipv4/ip_local_port_range) ?
That's it ?
Thanks a lot.
Best Regards.

rpc
rpc(n) Tnm Tcl Extension rpc(n)
__________________________________________________________________________________________________________________________________________________NAME
rpc - A simple RPC protocol for Tcl applications.
_________________________________________________________________DESCRIPTION RPC COMMAND
rpc server port
Set up an RPC server listening an port port. This command returns a rpc handle that be used to register Tcl procs that will be
exported by a trivial RPC protocol on top of TCP. This RPC mechanism allows us to write cooperating scripts without worrying much
about the communication protocol.
rpc client host port
Connect to the RPC server running on host with port port. The returned client handle can be used to invoke an exported proc on the
server host.
rpc delete handle
Delete a server or a client RPC handle. All connections associated with the handle will be closed.
rpc register rpchandle proc
Export proc as an RPC callable proc using the server handle rpchandle. Only registered procs can be called by RPC clients.
rpc unregister rpchandle proc
Remove proc from the list of exported procs on server handle rpchandle.
rpc info [rpchandle]
Calling rpc info without any arguments returns a list of all rpc handles that have been created using the rpc server and rpc client
command. Info about a specific rpc file handle rpchandle is returned by using the optional argument. The result is a list contain-
ing the tcp file handle used for the communication and the list of registered commands for a rpc handle and a list of all files that
represent connections to an rpc server. This list is empty if rpchandle belongs to a rpc client.
rpc# [-async] proc arg1 arg2 ...
To invoke a remote procedure proc, use the same syntax as used with a local invocation preceeded by a client rpchandle. The result
of the remote procedure call will be returned or an error if the underlying communication channel signals errors. The -async options
can be used to invoke proc without waiting for it to complete. The async option will never return a result.
