Agreed. Also, check the access rights set on the NAS end. I'm no MAC user either but perhaps your upgraded OS is checking acess rights on the NAS that it wasn't checking before.
Well, I'm about to give up. I've gone through every single permission and access rights option on the NAS, no luck. Again, what completely confuses me is that I can run the script manually from the shell and everything works perfectly. So I know that the NFS directory is mounted, and that root user can read the files in it. But as soon as it's a cron job or a launchd job that runs the script it can see the file, but can't read it.
The log simply says:
Without a doubt the upgrade to Catalina resulted in scripts being run within the context of cron or launchd to use a different environment than that of the command line. This approach of mine works on ALL my other Linux, *nix (SunOS, Solaris, HP-UX, AIX, Linux), heck, even OpenVMS, but no longer on Mac OS X. Grrrrr....
I have set up a samba share on my Linux server. I have a gigabit switch, gigabit NICs in each machine.
I have set up the /etc/samba/smb.conf to support no delay, 8192 send/receive buffers, etc. This helped the rate for Samba go from about 4MB/S to about 10MB/S, but I expect to see about... (1 Reply)

run_xfs_fsr is a xfs filesystem maintenance script designed to run under cron. The system is a home theater personal computer running mythbuntu 10.10, and is accessed remotely for these tests. cron runs a script, (xfs_fsr.sh) at 02:30 that runs the subject script under BASH and sets the...

Ok, so I have been struggling with this for a few days and I think I need an explanation of a few things before I go any further. I'm not sure it's possible to do what I'm trying, so before I pull my hair out, here is what I'm doing:
I have written a program in LiveCode that sits on our... (2 Replies)

nfs, NFS - network file system
DESCRIPTION
The Network File System (NFS) allows a client node to perform transparent file access over the network. By using NFS, a client node oper-
ates on files residing on a variety of servers and server architectures, and across a variety of operating systems. File access calls on
the client (such as read requests) are converted to NFS protocol requests and sent to the server system over the network. The server
receives the request, performs the actual file system operation, and sends a response back to the client.
NFS operates in a stateless manner using remote procedure calls (RPC) built on top of an external data representation (XDR) protocol. The
RPC protocol enables version and authentication parameters to be exchanged for security over the network.
A server grants access to a specific file system to clients by adding an entry for that file system to the server's file.
A client gains access to that file system using the command to request a file handle for the file system (see mount(1M)). (A file handle
is the means by which NFS identifies remote files.) Once a client mounts the file system, the server issues a file handle to the client
for each file (or directory) the client accesses. If the file is removed on the server side, the file handle becomes stale (dissociated
with a known file), and the server returns an error with set to
A server can also be a client with respect to file systems it has mounted over the network; however, its clients cannot directly access
those file systems. If a client attempts to mount a file system for which the server is an NFS client, the server returns with set to The
client must mount the file system directly from the server on which the file system resides.
The user ID and group ID mappings must be the same between client and server. However, the server maps UID 0 (the superuser) to UID -2
before performing access checks for a client. This process prevents gaining superuser privileges on remote file systems.
RETURN VALUE
Generally, physical disk I/O errors detected at the server are returned to the client for action. If the server is down or inaccessible,
the client receives the message:
where is the hostname of the NFS server. The client continues resending the request until it receives an acknowledgement from the server.
Therefore, the server can crash or power down, and come back up without any special action required by the client. The client process
requesting the I/O will block, but remains sensitive to signals (unless mounted with the option) until the server recovers. However, if
mounted with the option, the client process returns an error instead of waiting indefinitely.
