FIFO over NFS

Hi All

I am attempting to setup a FIFO over NFS. Directing and reading from the FIFO works fine on the local machine - however when I direct to the FIFO from a server which has the directory NFS mounted it does not work. The process that reads the write performed by the NFS client to the FIFO on the NFS server does not pickup the write (attempted write) to the FIFO.

Has anyone ever encountered this? Any solutions/ideas?

If I understand you correctly, then what you are trying won't work. A FIFO is a kernel interprocess communication channel that has a named representation in the filesystem. Basically, it is like a device entry in /dev. As such, it can only be local to the machine.

What you are describing is trying to setup a communication channel between two machines. A FIFO is not meant for that purpose. Use a UDP/TCP socket to communicate between machines.
