try this program i found it in the BTS regarding mutt and NFS: #include <fcntl.h> #include <errno.h> #include <stdio.h> int main (int argc, char *argv[]) { struct flock lck; int fd, ret; if (argc != 2) { printf ("Usage: %s file to lock\n", argv[0]); return 1; } fd = open (argv[1], O_RDONLY); memset (&lck, 0, sizeof (struct flock)); lck.l_type = F_RDLCK; lck.l_whence = SEEK_SET; ret = fcntl (fd, F_SETLK, &lck); printf ("fcntl()=%i, errno=%i\n", ret, errno); return 0; } it is supposed to test whether a lock can be established or not, iirc it returns errno=1 or such on failure (i tried it on userspace-nfs and got different results then with kernel-nfs) i don't know much else about it though. -- Ethan Benson http://www.alaska.net/~erbenson/
