Thread: subsitution for rcmd -> local command

hi everyone,

I m looking for a subsitution for rcmd(). i want make a client server application run on a standalone machine.

currently i am going with unix file sockets to replace rcmd() for creating a scoket connection.

my doubts are:
1. is there only one stdin, stdout and strerr sockets for a linux machine or if we open different termnals then will those terminals have their own stdin, stdout, stderr soket descriptors

2. Is it possible for a program running in one terminal to copy the standard io descriptors of other terminal.

3.can a program runnin in one terminal send data to the stdin descriptor of other terminal


i tried doing it but the parent prints the data in its own terminal not in client terminal

You can invoke processes on a remote machine and display their output on the client terminal by using ssh or rsh:

Code:

system("ssh username@hostname /path/to/command");

Or for rsh:

Code:

system("rsh hostname -l username /path/to/command");

Thanks

but the system is a blocking call and usin ssh or rsh wont help.,.

actually what i ws lookin for ws the exact opposite of rcmd something like local command.

as i have an server client program which i want to run on a standalone machine.

so finally got sucessful

what i did is created a UNIX file socket betwwen a server and a client program, and then on the client side closed the sdtin and sdtout descriptors and dupped then to the socket descriptor which i have created so now i dont need to change anythin else in my code .

so what i hv learned is

1. if u want to take out the network part in some server client application use unix file socket

2. if lookin for rcmd subsitute, somethin lik lcmd just do whatever i did.
