how to mount remote file system
In my case, there are serveral PCs running Linux in a LAN.
I would like to to mount the directory /A_river of machine-A to the file system of another machine machine-B so that I can access files in that directory.
I do not know how to do this. The situation is complicated by the following needs. I need /A_river of machine-A can be mounted by serveral machine, machine-B, machine-C, machine-D, etc. Shall I repeat the operations on each machine. What is the wise way to do this.
