I am having trouble using scp with NSTask. Only the standard error is sent to my filehandle. I have tried other commands with the code:

Code:

 //create task
        if (openpty(&master, &slave, devname, NULL, NULL) == -1)
        {
            [NSException raise:@"OpenPtyErrorException"
                        format:@"%s", strerror(errno)];
        }
        
        
        
        slaveHandle = [[NSFileHandle alloc] initWithFileDescriptor: slave]; //slave
        
       
       
        masterHandle = [[NSFileHandle alloc] initWithFileDescriptor: master closeOnDealloc:YES];//master
        
        [scp setStandardOutput: slaveHandle];
        [scp setStandardError: slaveHandle];
        [scp setStandardInput: slaveHandle];
        
        [scp setArguments:[NSArray arrayWithObjects: @"-v", filename,@"user@192.168.1.2:Public",  nil]];
        
        
        [scp setLaunchPath: @"/usr/bin/scp"];
        
        [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(readSCP:) 
        name: NSFileHandleReadCompletionNotification 
        object: masterHandle];
        
        [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(endSCP:) 
        name: NSTaskDidTerminateNotification 
        object: scp ];
        
        [masterHandle readInBackgroundAndNotify];
        
        
        [scp launch];

which work. Has anybody run into this problem or see in error in my code. Any help will be appreciated.

I have figured out that ssh uses ttyp0 for stdin/stdout. But I don't have permission to access that terminal. Has anyone had experience forcing the output by other means or a way of getting around the permissions?

thanks,
