I've got two Red Hat Linux boxes, running Red Hat 6.0. I can successfully mount an NFS directory on the client, and list the files, and display them. They all appear to have read-write priviledges, but I'm unable to edit a file, or write in any way to the NFS-mounted directory. This problem arises both as root and as an ordinary user. The NFS server has an /etc/exports file without tabs, and with a (rw) code immediately after the client name (no spaces). The machines as also linked in a NIS server-client relationship, running ypserv 126.96.36.199 (the ypserv 188.8.131.52 originally supplied on the RedHat CD didn't work properly with yppasswd).
A couple of oddities:
1. /proc/filesystems on the NFS server shows
I had expected to see nfs in there, yet nfs support is now supposed to be modular, so hoping that I don't have to rebuild the kernel (worry!)
2. The showmount command described in RedHat's NFS-Tips web document is missing from my machines.
I'm obviously overlooking something simple here. Many thanks in advance for any help.
