I have a resource manager which creates a node under /dev with permissions:

nrw-rw-r--  1 flight flight 0 Aug 26 13:27 server

My id is:

uid=101(nort) gid=0(root) groups=150(flight)

On the local node, I can:

  echo "Log Test" >/dev/.../server

but from another node:

  echo "Log Test" >/net/cs210/dev/.../server

I get permission denied. /etc/passwd and /etc/group are identical on the two systems. All intermediate nodes have world 
execute permission. If I:

  chmod o+w /dev/.../server

I can write from the remote node.

Any idea what the problem might be?
